PART I
ITEM 1. BUSINESS
Overview
We are a biopharmaceutical company focused on discovering, developing and commercializing novel small-molecule therapeutics derived
from our boron chemistry platform. We have demonstrated that our organization, utilizing our boron chemistry platform, is highly productive and efficient at creating novel clinical product candidates.
We have discovered, synthesized and developed seven molecules that are currently in development, and we believe that our organization and boron chemistry platform have the potential to continue to
yield clinical candidates at a similar pace and efficiency in the future. While drug development is often uncertain and occasionally uneven, our current portfolio of product candidates and our ability
to efficiently fill our own pipeline provide us with a unique opportunity to create a valuable and sustainable biopharmaceutical company.
We
believe that our expertise in boron chemistry enables us to identify compounds that interact with known drug targets in novel ways and also inhibit drug targets that have been
historically difficult to inhibit with traditional chemistry. We have applied this expertise across a range of fungal, inflammatory, bacterial and parasitic diseases that represent significant unmet
medical needs. We have discovered and advanced into clinical development multiple differentiated product candidates that we believe have significant disease-modifying potential and attractive
pharmaceutical properties. We believe that our product candidates may offer significant improvements over the standard of care for diseases that represent large, well-defined commercial
opportunities.
The
productivity of our internal discovery capability has enabled us to generate a pipeline of both topical and systemic boron-based compounds. We have discovered seven product
candidates that have reached development. Our lead product candidates include two topically administered dermatologic compoundstavaborole (formerly referred to as AN2690), an antifungal
for the treatment of onychomycosis, and AN2728, an anti-inflammatory for the treatment of atopic dermatitis and psoriasis. In addition, we have discovered three compounds that we have
out-licensed for further developmentGSK2251052, or GSK '052 (formerly referred to as AN3365), a systemic antibiotic for the treatment of infections caused by
Gram-negative bacteria that is licensed to GlaxoSmithKline LLC, or GSK; AN8194, for the treatment of an animal health indication that is licensed to Eli Lilly and Company, or Lilly;
and AN5568, also referred to as SCYX-7158, for human African trypanosomiasis (HAT, or sleeping sickness), which is licensed to Drugs for Neglected Diseases initiative, or DNDi.
We
have entered into and are seeking partnerships to expand the therapeutic application and commercial value of our boron chemistry platform. In October 2007, we entered into a research
and development collaboration, option and license agreement with GSK for the discovery, development and worldwide commercialization of boron-based systemic anti-infectives. In July 2010,
GSK exercised its option to license GSK '052, and we are actively conducting research to discover additional systemic anti-infectives with GSK. In September 2011, we amended and
expanded our research and development collaboration with GSK to provide GSK the option to extend its rights around the bacterial enzyme target leucyl-tRNA synthetase (LeuRS), as well as to
add new programs for tuberculosis (TB) and malaria using Anacor's boron chemistry platform. In August 2010, we entered into a collaboration with Lilly, under which we are collaborating to discover
products
for a variety of animal health applications. In August 2011, we announced that we achieved our first development candidate in animal health under this collaboration. In February 2011, we entered into
a research and development option and license agreement with Medicis Pharmaceutical Corporation, or Medicis, to discover and develop compounds directed against a target for the potential treatment of
acne. In addition, we are applying our boron chemistry platform to the development of treatments for various neglected diseases in collaboration with leading not-for-profit
organizations, including DNDi, Medicines for Malaria Ventures, or MMV, Sandler Center for Basic Research in Parasitic Diseases and the Institute for

Health. In March 2012, DNDi commenced the first human clinical trial for AN5568, the first oral drug candidate for sleeping sickness.
The following table summarizes the current status and the anticipated next steps in the development plans for our clinical-stage
product candidates:
Tavaborole
is our lead topical antifungal product candidate for the treatment of onychomycosis, a fungal infection of the nail and nail bed. Onychomycosis affects approximately
35 million people in the United States, and new prescriptions to treat this disease continue to grow. Lamisil (terbinafine), a systemic drug approved for onychomycosis, had worldwide peak sales
of $1.2 billion in 2004, before generic entry. According to IMS Health, for the 12-month period ending December 31, 2010, 1.4 million new prescriptions were filled in
the United States for both branded and generic versions of terbinafine. Despite its high labeled efficacy (38%), we believe the usage of branded and generic terbinafine has been limited due to safety
concerns related to liver toxicity. The leading topical drug for onychomycosis, Penlac Nail Lacquer (ciclopirox), had U.S. sales of $125.0 million in 2002, before generic entry. According to
IMS Health, for the 12-month period ending December 31, 2010, over
2
Table of Contents
375,000
new prescriptions were filled in the United States for branded or generic ciclopirox. While ciclopirox has been shown to be safe due in part to its topical administration, we believe the usage
of branded and generic ciclopirox has been limited due to its low labeled efficacy (5.5% - 8.5%).
We
believe tavaborole can potentially offer significant improvements over the standards of care for onychomycosis by combining the safety of a topical drug with significant efficacy. Due
to its unique boron chemistry, tavaborole has demonstrated enhanced nail penetration properties, a novel mechanism of action with potent antifungal activity and, due in part to its topical
administration, no observed systemic side effects in human dosing. Tavaborole inhibits an essential fungal enzyme, leucyl-transfer RNA synthetase, or LeuRS, required for protein synthesis. The
inhibition of protein synthesis leads to termination of cell growth and cell death, eliminating the fungal infection. We reported positive results from three Phase 2 clinical trials and held an
end-of-Phase 2 meeting with the United States Food and Drug Administration, or FDA. In August 2010, we filed a Special Protocol Assessment, or SPA, request with the FDA
and reached agreement on the major parameters associated with the design and conduct of our two current Phase 3 clinical trials of tavaborole. We completed enrollment in both Phase 3
trials in the fourth quarter of 2011.
AN2728
is our lead topical anti-inflammatory product candidate for the treatment of atopic dermatitis and psoriasis. Atopic dermatitis is a chronic rash characterized by
inflammation and itching. In 2007, Datamonitor reported that atopic dermatitis affected approximately 40 million people across the seven major pharmaceutical markets. The condition most
commonly appears in childhood, with up to 20% of children in the United States affected, and it can persist into adulthood. Skin affected by atopic dermatitis can often be broken and chafed from
scratching which allows bacterial or viral access that can lead to secondary infections. Current atopic dermatitis treatments attempt to reduce inflammation and itching to maintain the protective
integrity of the skin. Antibiotics, antihistamines, topical corticosteroids and topical immunomodulators, either as monotherapy or in combination, are the current standard of care for atopic
dermatitis. However, these can be limited in utility due to insufficient efficacy or unwanted side effects. Psoriasis is a chronic inflammatory skin disease that affects approximately
7.5 million people in the United States and over 100 million people worldwide. Approximately 80% of psoriasis patients have mild-to-moderate disease, which is
mainly treated with topical corticosteroids and vitamin D analogs. However, topical corticosteroids and vitamin D analogs are limited in their use by patients due to their long-term safety
and/or their tolerability profile. In spite of these limitations, according to IMS Health, approximately 3.9 million prescriptions were filled for these topical therapies to treat psoriasis in
the United States in 2009.
We
believe that AN2728 has the potential to be an effective treatment for atopic dermatitis and psoriasis with an attractive safety profile in a topical application, and thus provide an
alternative to treatment with topical corticosteroids and topical immunomodulators for atopic dermatitis and topical corticosteroids and vitamin D analogs for psoriasis. Due to its boron-based
structure, AN2728 binds
with the active site of the enzyme phosphodiesterase-4 (PDE-4) in a novel manner, inhibits its activity, and reduces the production of a range of pro-inflammatory cytokines
that are thought to be associated with atopic dermatitis and psoriasis.
In
December 2011, we reported the results of a Phase 2a trial of AN2728 and AN2898, our second topical anti-inflammatory product candidate for the treatment of atopic
dermatitis. The primary endpoint for both compounds was successfully achieved after 28 days of twice-daily treatment. In the final analysis, 68% of AN2728-treated lesions showed
greater improvement in Atopic Dermatitis Severity Index (ADSI) score versus 20% for vehicle (P = 0.02) and 71% of AN2898-treated lesions showed greater improvement in ADSI score
versus 14% for vehicle (P = 0.01). There were no severe adverse events reported that were considered related to either study drug.
In
June 2011, we successfully completed a final Phase 2b trial for AN2728 in psoriasis in which patients were randomized to receive either AN2728 or vehicle, a design that matched
the anticipated
3
Table of Contents
conduct
of our future Phase 3 trials. In October 2011 we held an End-of-Phase 2 meeting with the FDA to discuss the design of Phase 3 trials of AN2728 in
psoriasis and, in November 2011, we filed an SPA and reached agreement with the FDA on the major parameters associated with the design and conduct of the Phase 3 trials of AN2728 in psoriasis.
GSK '052
is our lead systemic antibiotic for the treatment of infections caused by Gram-negative bacteria. Gram-negative bacterial infections are
increasing in prevalence, especially in hospitals, and represent a serious public health challenge due to their growing resistance to currently available drug therapies. According to the
New England Journal of
Medicine
, it is estimated that there were 1.7 million hospital-acquired Gram-negative and
Gram-positive infections and approximately 100,000 associated deaths in the United States alone in 2002. The
New England Journal of Medicine
also indicates that Gram-negative bacteria are responsible for more than 30% of hospital-acquired infections and account for approximately 70% of hospital-acquired infections in the
intensive care unit. IMS Health estimates there were 40 million days of Gram-negative therapy administered in the United States in 2009. Gram-negative bacterial
infections are becoming a major global health issue as their growing resistance to currently available drug therapies is rapidly increasing. Furthermore, recently approved Gram-negative
antibiotics have been limited to new versions of existing antibiotics, which carry the risk of rapid resistance development from pre-existing mechanisms of resistance. Preclinical studies
suggest that GSK '052 could be a novel approach for the treatment of infections caused by a broad range of Gram-negative bacteria, including
E.
coli
,
Klebsiella pneumoniae
,
Citrobacter spp.
,
S. marcescens
,
P. vulgaris
,
Providentia
spp.
,
Pseudomonas aeruginosa
and
Enterobacter spp.
Due
to its unique boron-based chemical structure, GSK '052 specifically targets the bacterial enzyme LeuRS which is required for protein synthesis. The inhibition of protein
synthesis leads to termination of cell growth and cell death, eliminating the bacterial infection. In preclinical safety, pharmacology and toxicology studies, GSK '052 showed robust activity
against multi-resistant Gram-negative bacteria with no cross resistance to existing classes of antibiotics. In a Phase 1 proof-of-concept trial,
GSK '052 demonstrated a promising safety profile and linear dose-proportional pharmacokinetic properties, reaching blood levels that were many times higher than the anticipated
efficacious dose. If approved, we believe GSK '052 would be the first new class of antibacterial agents to treat serious hospital-acquired Gram-negative infections in thirty years.
In addition, we believe GSK '052 has the potential to be the first antibiotic specifically targeting infections caused by Gram-negative bacteria that can be administered by both IV
and oral routes, which would allow patients to continue on the same antibiotic therapy they received in the hospital once they are discharged.
Following
the completion of the Phase 1 trial, GSK exercised its option to obtain an exclusive license to develop and commercialize GSK '052 and has assumed responsibility
for further development of the product candidate and any resulting commercialization. Upon exercise of the option in July 2010, we received a fee of $15.0 million. In June 2011, GSK initiated
two Phase 2b trials for complicated urinary tract infections, or cUTI, and complicated intra-abdominal infections, or cIAI. In September 2011, GSK was awarded a contract with the U.S.
Department of Health and Human Services' Biomedical Advanced Research and Development Authority, or BARDA, to support the ongoing development of GSK '052. The contract provides up to
$94 million in funding for up to four years to support studies to evaluate the efficacy of GSK '052 against bioterrorism threats, Phase 2 clinical trials for ventilator-associated
pneumonia, and Phase 3 trials for complicated intra-abdominal infections.
In
March 2012, GSK voluntarily discontinued certain of its current clinical trials of GSK '052 due to a recently identified microbiological finding in a small number of patients
in the Phase 2b trial of GSK '052 for the treatment of cUTI. While we believe the microbiological finding seen in the cUTI study is not related to the safety of GSK '052, the
potential to negatively impact efficacy led GSK to voluntarily discontinue that study as well as the Phase 2b study in cIAI and one of two Phase 1 studies in healthy volunteers. GSK is
in the process of obtaining and analyzing additional information from all
4
Table of Contents
enrolled
subjects. Upon completion of this analysis, GSK will consider options for the future development of GSK '052. Pending the continued development of GSK '052, we would be eligible
to receive potential development milestones up to $75.0 million, commercial milestones up to $175.0 million and double-digit tiered royalties with the potential to reach the
mid-teens on annual net sales.
In
August 2010, we entered into a research agreement with Eli Lilly and Company, or Lilly, under which we are collaborating to discover products for a variety of animal health
applications, and Lilly is responsible for worldwide development and commercialization of compounds advancing from these efforts. In August 2011, Lilly selected AN8194 as the first development
candidate in animal health under this collaboration, and we received a $1.0 million milestone payment. In addition, we will be eligible to receive payments upon the achievement of development
and regulatory milestones, as well as tiered royalties, escalating from high single digit to in the tens, on sales depending in part upon the mix of products sold. Such royalties continue through the
later of expiration of our patent rights or six years from the first commercial sale on a product-by-product and country-by-country basis.
In
December 2007, we established a partnership with DNDi to develop new therapeutics for sleeping sickness, visceral leishmaniasis and Chagas disease. In March 2012, DNDi commenced
Phase 1 human clinical trials of AN5568 for sleeping sickness. AN5568 is a product of Anacor's boron chemistry and the first oral drug candidate for sleeping sickness.
Our
clinical pipeline also includes two additional product candidates that may extend and expand the market opportunity of our dermatology portfolio. AN2718, our second topical
antifungal product candidate, has the potential to treat onychomycosis and fungal infections of the skin. AN2898, our second topical anti-inflammatory product candidate, has the potential
to treat atopic dermatitis and psoriasis. In December 2011, AN2898 successfully met the primary endpoint in the Phase 2a trial in atopic dermatitis.
Boron Chemistry Platform
All of our current research and development programs, including our seven development-stage product candidates, are based on compounds
that have been internally discovered using our boron chemistry platform. Boron is a naturally occurring element that is ingested frequently through consumption of fruits, vegetables, milk and coffee.
Boron has two attributes that we believe confer compounds with drug-like properties. First, boron-based compounds have a unique geometry that allows them to have two distinct shapes,
giving boron-based drugs the ability to interact with biological targets in novel ways and to address targets not amenable to intervention by traditional carbon-based compounds. Second, boron's
enhanced reactivity as compared to carbon allows us to design molecules that can hit targets that are difficult to inhibit with carbon chemistry.
Despite
the ubiquity of boron in the environment, researchers have faced challenges in evaluating boron-based compounds as product candidates due to previously limited understanding of
the physical properties necessary to provide boron-based compounds with the chemical and biological attributes required of pharmaceutical therapies as well as difficulty in chemical synthesis.
We
have developed expertise and an understanding of the interactions of boron-based compounds with key biological targets relevant to treating disease. This know-how is
primarily related to methods for modulating boron's reactivity to optimize reactions with the target and minimize unwanted chemical reactivity. Our advances have enabled the efficient optimization of
disease-modifying properties for our lead compounds and their rapid progression from the research stage into clinical trials.
Additionally,
we have discovered new methods of synthesis of boron compounds, allowing for the creation of new compound families with broad chemical diversity and retention of
drug-like properties. These new compound families expand the universe of biological targets that can be addressed by small-
5
Table of Contents
molecule,
boron-based compounds. We have been in operation since 2002 and began generating clinical candidates in our second year of operations. Since that time, we have discovered and synthesized
thousands of boron-containing molecules and, of these, seven have reached development stage. The rate of discovery of molecules and promotion to clinical development has occurred at a relatively
constant rate.
We
believe our focus on boron-based chemistry provides us with multiple advantages in the small-molecule drug discovery process. These advantages include:
-
-
Novel access to biological targets.
Due to the unique
geometry and reactivity of boron-based molecules, our boron-based compounds are able to modulate existing biological targets and can address targets not amenable to intervention by traditional
carbon-based compounds. This may enable us to treat diseases that have not been effectively addressed by carbon-based compounds, for example, by developing antibiotic or antifungal therapies that kill
pathogens that have become resistant to existing drugs.
-
-
Broad utility across multiple disease areas.
Our compounds
have exhibited extensive preclinical activity in multiple disease areas, including fungal, inflammatory and bacterial diseases, which are our core areas of focus, as well as in parasitic, cancer and
ophthalmic indications and for applications in animal health.
-
-
Rapid and efficient synthesis of drug-like
compounds.
Our proprietary technological advances in the synthesis of boron-based compounds, coupled with our rational drug design
capabilities, have enabled us to rapidly create large families of boron-based compounds with drug-like properties. We believe that these advances have made manufacturing of boron-based
compounds economical on a commercial scale.
-
-
Unencumbered intellectual property landscape.
We believe
the intellectual property landscape for boron-based pharmaceutical products is relatively unencumbered compared to that of carbon-based products, providing an attractive opportunity for us to build
our intellectual property portfolio.
Our Strategy
Our objective is to discover, develop and commercialize proprietary boron-based drug compounds with superior efficacy, safety and
convenience for the treatment of a variety of diseases. The key elements of our strategy to achieve this objective are to:
-
-
Drive rapid, efficient discovery of novel boron-based
compounds.
We believe the unique characteristics of boron and the expertise we have developed allow us to design novel product
candidates that target a broad range of diseases and drive a rapid and efficient drug development process. During our first ten years of operations, we have discovered and advanced seven compounds
that are currently in development and, in addition, have other active research and development programs ongoing.
-
-
Focus development activities in our core therapeutic
areas.
We intend to focus our development activities in our core therapeutic areas of fungal, inflammatory and bacterial diseases. To
fully leverage our boron chemistry platform, we have established and will continue to pursue development partnerships in these therapeutic areas.
-
-
Commercialize our products ourselves in specialty markets in the United
States.
We intend to build a sales force to focus on domestic specialty markets, such as dermatology and podiatry. We have entered into
and will continue to seek commercialization partners for products in non-specialty and international markets.
6
Table of Contents
-
-
Leverage partnerships for non-core therapeutic
areas.
We believe boron chemistry has utility in a broad range of diseases outside of our core therapeutic areas. To maximize the value
of our boron chemistry platform and to provide non-dilutive capital to support development in our core therapeutic areas, we have entered into and will continue to seek partnerships early
in development for compounds in non-core areas, such as parasitic, cancer and ophthalmic indications and for applications in animal health.
-
-
Expand and protect our intellectual property.
We intend to
expand and aggressively prosecute our intellectual property in the area of boron chemistry and boron-based compounds. Since a relatively limited amount of research has been done in the area of
boron-based drug development, we believe that we can establish a defensible and valuable intellectual property portfolio.
Our Product Candidates
Our Topical Antifungal Programs
Our most advanced product candidate is tavaborole, a topical treatment for onychomycosis, which is a fungal infection of the nail and
nail bed. We have reported positive results from three Phase 2 clinical trials and completed enrollment in two Phase 3 trials in the fourth quarter of 2011.
Onychomycosis is primarily caused by dermatophytes, which are fungi that infect the skin, hair or nails. The infection involves the
nail plate, the nail bed and, in some cases, the skin surrounding the nail plate. Onychomycosis causes nails to deform, discolor, thicken, become brittle and split and separate from the nail bed.
Toenails affected by onychomycosis can become so thick that routine trimming of the nails becomes difficult. The condition can also cause pain when individuals wear shoes, leading to difficulties
walking. Onychomycosis can also lead to social embarrassment due to the unsightly appearance of the infected nails and because it may be perceived to be an active infection and contagious.
According
to
Podiatry Today
, 35 to 36 million people in the United States have onychomycosis. Over 95% of onychomycosis infections
are infections of the toenail, according to a report in
U.S. Dermatology Review
. According to the manufacturer of Lamisil, 47% of those affected by
onychomycosis are not receiving treatment. For those who do seek treatment, options include debridement, oral or topical drugs or a combination of debridement and drug therapies. Debridement consists
of scraping, cutting away or removal of the affected nail. Onychomycosis may persist or worsen if not treated. Onychomycosis often recurs in susceptible individuals because the fungi that cause
onychomycosis are present in many common locations such as floors, the soil, socks and shoes. Consequently, the nail can be reinfected, and additional courses of treatment are frequently required even
after successful treatment.
Lamisil
(terbinafine), a systemic drug approved for onychomycosis, had worldwide peak sales of $1.2 billion in 2004, before generic entry. According to IMS Health, for the
12-month period ending December 31, 2010, 1.4 million new prescriptions were filled in the United States for both branded and generic versions of terbinafine. Despite its
high labeled efficacy (38%), we believe the usage of branded and generic terbinafine has been limited due to safety concerns related to liver toxicity. Penlac Nail Lacquer (ciclopirox), the only U.S.
approved topical agent for onychomycosis, had U.S. sales of $125.0 million in 2002, before generic entry. According to IMS Health, for the 12-month period ending December 31,
2010, over 375,000 new prescriptions were filled in the United States for branded or generic ciclopirox. While ciclopirox has been shown to be safe due in part to its topical administration,
7
Table of Contents
we
believe the usage of branded and generic ciclopirox has been limited due to its low labeled efficacy (5.5% - 8.5%).
Current therapies for onychomycosis include debridement and drug therapies. Debridement is time consuming and only marginally effective
in eliminating the fungal infection. Drug therapies are available in two types, either oral therapies such as Lamisil, or topical therapies such as Penlac. According to the Lamisil product label, 38%
of patients treated in clinical trials with a 12-week course of therapy achieved 100% clear nail and mycological cure. However, Lamisil has been associated with rare cases of liver
failure, some leading to death or liver transplant. We believe this risk of liver failure limits acceptance of this therapy by both physicians and patients. Patients are recommended to undergo liver
function tests prior to initiating Lamisil treatment and those patients with pre-existing liver disease cannot be treated with it.
Penlac
is approved for use in onychomycosis in conjunction with frequent debridement. In the two clinical trials cited on Penlac's product label, even with frequent debridement, only
5.5% and 8.5%, respectively, of patients treated with Penlac achieved 100% clear nail and mycological cure. We believe that a significant barrier to effective treatment by current topical therapies is
the difficulty of formulating the drug product to penetrate through the nail plate and reach the site of infection.
By addressing the limitations of current therapies, we believe tavaborole has a potential safety and efficacy profile that can make it
a best-in-class therapy for the treatment of onychomycosis. We have completed three Phase 2 clinical trials in which tavaborole demonstrated statistically significant
efficacy relative to vehicle and had no observed systemic side effects. We believe that the clinical data that we have generated to date demonstrates the potential advantages of tavaborole relative to
Lamisil and Penlac. Tavaborole is currently being evaluated in two Phase 3 trials for onychomycosis.
We
have designed tavaborole, our topical antifungal, with three distinguishing characteristics:
-
-
Enhanced nail penetration properties.
We utilized our
expertise in medicinal chemistry to design tavaborole with enhanced nail penetration properties, allowing for improved delivery of the compound through the nail plate to the nail bed, the site of
onychomycosis infection. Preclinical studies utilizing human nails indicate that tavaborole is able to penetrate the nail plate 250 times more effectively than Penlac.

Novel mechanism of action with potent antifungal activity.
We have
utilized our expertise in boron-based chemistry to design tavaborole with potent antifungal activity. Tavaborole inhibits an essential fungal enzyme, leucyl-transfer RNA synthetase, or LeuRS, required
for protein synthesis. The inhibition of protein synthesis leads to termination of cell growth and cell death, eliminating the fungal infection. We have shown that this inhibitory activity requires
the presence of boron within the compound, as the replacement of the boron atom with a carbon atom in tavaborole inactivated the molecule. The unique boron-based mechanism of action underlying
tavaborole was detailed in the June 22, 2007 issue of the journal
Science
.

No detected systemic side effects after topical dosing.
We
have conducted clinical trials to assess systemic absorption of tavaborole. The results of these trials found that topical treatment with tavaborole resulted in low or no detectable levels of drug in
the blood or urine. No treatment-related systemic side effects have been observed in any of our clinical trials, and we believe it is unlikely that treatment of onychomycosis with tavaborole will
result in significant systemic side effects.

We
have completed three Phase 2 clinical trials which demonstrated that tavaborole is efficacious as defined by the percentage of patients achieving clear nail growth and negative
fungal culture. We believe that these data have demonstrated that tavaborole's efficacy should be in a range that is at least twice that of Penlac and may approach that of Lamisil. In addition, in our
Phase 1 and Phase 2 clinical trials, we have shown that tavaborole achieves significant nail penetration, results in little or no systemic exposure and is well-tolerated
across a range of doses.
In the fourth quarter of 2011 we completed enrollment in two Phase 3 clinical trials for tavaborole in onychomycosis. The
Phase 3 program consists of two double-blind, vehicle-controlled trials of approximately 600 patients each. Vehicle refers to the topical solution without the active ingredient.
Two-thirds of the patients were randomized to receive tavaborole at the 5.0% concentration, or dose, compared to one-third who receive vehicle once daily for 48 weeks.
The primary efficacy endpoint is a composite endpoint measuring complete cure of the great toenail at week 52, which is consistent with the FDA endpoint requirement for Lamisil. Complete cure requires
both a mycologic cure and a completely clear nail. Mycologic cure is achieved when the fungus present in the nail plate is killed by treatment. Achieving a clear nail requires a complete elimination
of the diseased portion of the nail by replacement with a new healthy growing nail and nail bed. Given the slow rate of nail growth, which is approximately one to two millimeters per month, the
industry standard for conducting Phase 3 clinical trials of onychomycosis is to evaluate the nails over a 12-month period, in order to allow sufficient time for patients to grow a
new nail. In August 2010 we filed an SPA request with the FDA and reached agreement on what we believe are the major parameters associated with the design and conduct of our Phase 3 trials for
tavaborole. The Phase 3 trials are being conducted at clinical sites in the United States, Canada and Mexico. Guidance meetings have also been completed with the European Medicines Agency and
regulatory authorities in Japan. Based upon these discussions, we anticipate that our Phase 3 development program will help support approval in these regions, although an additional comparator
trial will likely be required in these regions.
Our Phase 2 clinical trials of tavaborole enabled us to define multiple well-tolerated, efficacious doses and a
dose-response relationship. We have also demonstrated that topical application to the toenails has led to little or no detectable systemic drug exposure in blood or urine. Results from
these trials supported the selection of the 5.0% dose of tavaborole for the Phase 3 clinical trials and enabled appropriate statistical calculations for the design of those trials.

In our Phase 2 clinical trials, we enrolled onychomycosis patients representative of a wide clinical spectrum of the disease. We believe
that the results of these trials indicate that tavaborole may effectively treat patients who are representative of the population that would seek treatment for onychomycosis.

The primary objectives of Study 200/200a were to demonstrate that the efficacy of tavaborole could be differentiated from vehicle, and
to select the appropriate dose of tavaborole for Phase 3 clinical trials. A total of 187 patients were enrolled at multiple sites in Mexico and the United States. Enrolled patients were
randomly assigned to be dosed with the vehicle or one of the following concentrations of tavaborole solution: 2.5%, 5.0% or 7.5%. The double-blind nature of the trial ensured that neither the patients
nor the investigators were aware of which of the four treatment options was being applied. Patients dosed themselves daily for the first three months and three times per week for the remaining three
months of the six-month treatment period. After an additional six months of follow-up, complete and partial responders were identified and post-treatment effects
were assessed.
The
study's primary endpoint was the number of patients with at least two millimeters of clear nail growth and negative fungal culture at the end of the six-month treatment
period. At this time point, 27% of patients receiving the 2.5% dose, 26% of patients receiving the 5.0% dose and 32% of patients receiving the 7.5% dose were observed to achieve the trial's primary
endpoint, compared to 14% of patients receiving the vehicle. Overall, significantly more patients treated with tavaborole
achieved the primary endpoint, compared with the vehicle (P-value of 0.03). Of 187 enrolled patients, four subjects experienced five episodes of skin irritation, and four of these episodes
were observed in patients receiving tavaborole at the highest dose level. Based upon these results, we believe the 5% dose will offer patients the best combination of efficacy and tolerability and
therefore, we selected this dose for advancement into our Phase 3 clinical trials.
Study 201: Open-Label (first, second and third cohorts)Safety and Efficacy
The objective of Study 201 was to determine the safety and efficacy of 5.0% and 7.5% topical solutions of tavaborole in treating
onychomycosis. A total of 60 patients were enrolled at multiple sites in Mexico in the first two cohorts. Half received a 5.0% daily dose and the other half received a 7.5% daily dose for a period of
six months, with a subset of patients receiving an additional six months of follow-up assessment. The trial was open-label, such that both investigators and the patients knew
which dose was being administered. The study's primary endpoint was the number of patients with at least two millimeters of clear nail growth at six months and a negative fungal culture. At the end of
the six-month treatment period, 43% of patients receiving the 5.0% dose and 53% of patients receiving the 7.5% dose were observed to have achieved the trial's primary endpoint.
The
primary objective of the third cohort of Study 201 was to evaluate the safety of a longer treatment period of tavaborole in onychomycosis. In this open-label trial,
patients received a 5.0% dose once daily for up to 360 days. A total of 29 patients were enrolled in this cohort, which indicated that 5.0% tavaborole solution applied daily for 360 days
was well-tolerated by most subjects. At the end of the 12-month period, tolerability was shown to be similar to what was previously seen with 24 weeks of treatment. In
addition, 14% and 24% of the patients treated in the third cohort reached the endpoint of at least two millimeters of clear nail growth and negative fungal culture at six months and twelve months,
respectively. Seven percent of the third cohort patients demonstrated a completely clear nail and negative fungal culture after twelve months of dosing.
The objective of Study 203 was to determine safety and efficacy of lower dosing and less frequent dosing of tavaborole in treating
onychomycosis. Two groups of 30 patients were enrolled at multiple sites in the United States. Half applied a 1.0% daily dose for six months and the other half applied a 5.0% daily dose for the first
month, then three times per week for the remaining five months of treatment. A subset of each treatment group was followed for an additional six months after the end of treatment. The study's primary
endpoint was the number of patients with at least two millimeters of
10

clear
nail growth at six months and a negative fungal culture. At the end of the six-month treatment period, 30% of patients receiving the 1.0% dose and 50% of patients receiving the 5.0%
dose achieved the primary endpoint.
We believe we have completed all of the preclinical toxicology studies required for marketing approval, including a chronic
(nine-month) dermal minipig study, two-year mouse and rat carcinogenicity studies and definitive characterization of ADME (absorption, distribution, metabolism, and excretion)
in animals.
In February 2007, we entered into an exclusive license, development and commercialization agreement with Schering-Plough Corporation,
or Schering, for the development and worldwide commercialization of tavaborole. Under the agreement, Schering paid us a $40.0 million upfront fee and $9.5 million for our
development-related transition activities and assumed sole responsibility for development and commercialization of tavaborole. In addition, Schering invested $10.0 million in a preferred stock
financing completed in December 2008. In October 2009, the end-of-Phase 2 meeting with the FDA was completed. In November 2009, Schering merged with
Merck & Co., Inc., or Merck, and in May 2010, pursuant to a mutual termination and release agreement, we regained the exclusive worldwide rights to tavaborole. Merck did not
retain any rights to this compound. Upon returning rights to tavaborole in May 2010, Merck transferred back to us all materials and documents relating to tavaborole and paid us $5.8 million.
The sponsorship of the U.S. Investigational New Drug, or IND, from Schering to Anacor was completed in May 2010.
AN2718 is our second topical antifungal in clinical development for onychomycosis and fungal infections of the skin and utilizes the
same mechanism as tavaborole. AN2718 appears to be well-suited to target organisms that cause common skin and topical fungal infections, including
Trichophyton
and
Candida
fungi. Based on preclinical studies and in comparison to tavaborole, we believe
that AN2718 has greater potency against the dermatophytes
T. mentagrophytes
and
T. rubrum
and results in
similar nail penetration. These studies suggest that, like tavaborole, AN2718 also has significantly greater nail penetration than Penlac.
Our
Phase 1 data for AN2718 has also indicated that AN2718 has a low skin irritation profile across multiple doses and that it would thus be suitable for the treatment of skin
fungal infection. This Phase 1 data, which we announced in March 2009, was from a 21-day skin irritation trial. In the trial, we compared AN2718 gel at 1.5%, 2.5%, 5.0% and 7.5%,
and AN2718 cream at 0.3% and 1.0% to their respective vehicles. All doses of AN2718 gel, cream and vehicle were applied to the skin of normal volunteers for 21 days using
semi-occlusive, or semi-air and water-tight, adhesive patches. Application sites were then evaluated daily for signs of irritation. The irritation indices for all AN2718 doses
were very low and comparable to vehicle.
Our Topical Anti-Inflammatory Programs
AN2728 is our lead topical anti-inflammatory product candidate for the treatment of atopic dermatitis and psoriasis,
chronic inflammatory skin diseases that affect millions of people worldwide. To date, AN2728 has demonstrated initial tolerability and activity against atopic dermatitis in one Phase 2a trial
and against psoriatic lesions in three Phase 1b, one Phase 2a, one Phase 2 and two Phase 2b clinical trials. In October 2011, we held an
End-of-Phase 2 meeting with the FDA to discuss the design
11
Table of Contents
of
Phase 3 trials of AN2728 in psoriasis and in November 2011, we filed a SPA, and reached agreement with the FDA on the major parameters associated with the design and conduct of the
Phase 3 trials of AN2728 in psoriasis.
Given
the safety profile exhibited by AN2728 in 13 clinical studies, the positive outcome from the Phase 2a atopic dermatitis trial and the large unmet medical need in atopic
dermatitis relative to psoriasis, we intend to focus AN2728 development activities in 2012 on additional Phase 2 trials in atopic dermatitis and will defer the start of Phase 3 trials in
psoriasis.
Atopic dermatitis is a chronic rash characterized by inflammation and itching and usually occurs in people who have a personal or
family history of asthma or seasonal or perennial allergic rhinitis. In 2007, Datamonitor reported that atopic dermatitis affected approximately 40 million people across the seven major
pharmaceutical markets. The condition most commonly appears in childhood, with up to 20% of children in the United States affected, and it can persist into adulthood. Atopic dermatitis is the eighth
most common disease in persons under 25 years of age and is a common cause for pediatric healthcare visits, nonetheless, it continues to be frequently misdiagnosed, misunderstood and
ineffectively treated. While the exact cause of atopic dermatitis is not known, patients have a number of characteristics, including: a family tendency towards atopy, i.e., asthma, hay fever
and atopic dermatitis; an impaired skin barrier function; dry skin; a lower than normal threshold for itching; increased susceptibility to bacterial as well as viral, fungal and yeast skin infections
and abnormal immune and/or inflammatory responses. The secondary infections and/or greater than normal levels of bacterial colonization may be due to deficiencies in these patients' innate immunity.
At least some of the inflammatory responses are driven by host responses to the super antigens of Staphylococcus aureus. Lesions of atopic dermatitis are commonly red, elevated, scaly, excoriated and
oozing patches and are often accompanied by intense, unrelenting pruritus. The lesions lichenification, a thickening of the skin with exaggerated skin lines, is considered to be atrophic response to
chronic rubbing.
Current atopic dermatitis treatments attempt to reduce inflammation and itching to maintain the protective integrity of the skin.
Antibiotics, antihistamines, topical corticosteroids and topical immunomodulators, either as monotherapy or in combination, are the
current standard of care for atopic dermatitis. However, these can be limited in utility due to insufficient efficacy or unwanted side effects. The most recently approved non-steroidal
topical therapies for atopic dermatitis were Protopic and Elidel, topical immunomodulators, which received Black Box warnings from the FDA in 2005.
Psoriasis is a chronic inflammatory skin disease that affects approximately 7.5 million people in the U.S. and over
100 million people worldwide. Patients can be categorized as mild, moderate or severe, with approximately 80% of patients having mild to moderate forms of the disease. Psoriasis is
characterized by thickened patches of inflamed, red skin covered with thick, silvery scales typically found at the elbows, knees, scalp and genital area. The disorder ranges from a single, small,
localized lesion in some patients to a severe generalized eruption. Patients with mild-to-moderate psoriasis are typically treated with a combination of topical therapies,
while patients with moderate-to-severe psoriasis are typically treated with a combination of topical and systemic therapies. The recent introductions of new systemic biologic
therapies have provided new treatment options for patients with moderate to severe disease and have greatly expanded amounts spent on drugs to treat psoriasis. According to LeadDiscovery, sales of
psoriasis drugs in the seven major pharmaceutical markets (United States, Japan, France, Germany, Italy, Spain and the United Kingdom) were $2.5 billion in
12
Table of Contents
2008.
In 2009, over 4.5 million prescriptions were written for patients with psoriasis in the United States, with approximately 3.9 million of these prescriptions written for topical
therapies.
Most psoriasis patients use more than one type of treatment at any given time and may rotate treatments over time as their disease
severity changes or they develop complications. Although current treatments attempt to decrease the severity of the disease, none of them cures the disease. Currently available treatments can be
classified as topical, oral, injectable or phototherapy. According to IMS Health, 84% of all prescriptions for psoriasis within the United States in 2009 were for topical treatments. The most common
topical treatments are corticosteroids, vitamin D derivatives, such as Dovonex (calcipotriene), topical retinoids, such as Tazorac (tazarotene), and crude coal tar preparations. Taclonex is also a
treatment for psoriasis and is a combination of
calcipotriene and the high potency corticosteroid betamethasone dipropionate. The most common oral treatments are the immunosuppressive drug methotrexate and the oral retinoid acitretin. A number of
injectable biologic drugs in the market include Amevive, Enbrel, Humira, Remicade, Stelara and Simponi. The majority of these drugs are monoclonal antibodies, complex protein molecules, some of which
act by the inhibition of TNF-alpha. In addition to topicals, orals and injectables, psoriasis is also treated with ultraviolet light exposure. Typically, physicians initiate treatment by
prescribing topical therapies to treat mild or moderate forms of psoriasis, followed by light therapy or oral treatments if the patient's disease does not improve. For patients who do not respond to
oral treatments or light therapy, or for those who have moderate-to-severe psoriasis, physicians will prescribe injectable biologic treatments.
Current
topical therapies have demonstrated varying levels of efficacy. However, their use has been limited due to issues of safety and tolerability. Long-term use of topical
corticosteroids is associated with atrophy, or thinning, of the skin and has the potential to suppress the body's ability to make normal amounts of endogenous corticosteroids, which limit the duration
of safe treatment with these therapies. Vitamin D derivatives can cause skin irritation, and some patients report burning sensations associated with their use. Topical retinoids can also cause skin
irritation and have been shown to cause birth defects. Thus, their use must be avoided during pregnancy. Oral and injectable drugs have greater activity than topical therapies, but also have
well-documented and significant systemic side effects, such as liver toxicity, increase in blood fats and suppression of the immune system. In addition, injectable biologic drugs are very
expensive, costing tens of thousands of dollars annually. Ultraviolet light treatments can be effective, but require multiple visits to the doctor's office each week and may increase patients' risk of
developing skin cancer.
We believe that AN2728 will have comparable efficacy to that of topical immunomodulators in treating atopic dermatitis and comparable
efficacy to that of topical mid-potency corticosteroids and vitamin D analogs in treating psoriasis, but with a better safety and tolerability profile. AN2728 is a novel boron-containing
small molecule that inhibits PDE-4 and reduces the production of pro-inflammatory cytokines thought to be associated with atopic dermatitis and psoriasis. If approved, AN2728 would be the
first topical non-steroidal treatment that inhibits TNF-alpha release. Because AN2728 has a novel mechanism of action, it can potentially be combined with topical
corticosteroids and vitamin D analogs for patients with mild-to-moderate psoriasis. In addition, patients with severe psoriasis who combine topical and systemic therapies may
use AN2728.
In December 2011, we announced the results of a Phase 2a trial of AN2728 and AN2898, our second topical
anti-inflammatory product candidate, for the treatment of atopic dermatitis. The primary endpoint for both compounds was successfully achieved after 28 days of twice-daily
treatment. In the
13
Table of Contents
final
analysis, 68% of AN2728-treated lesions showed greater improvement in ADSI score versus 20% for vehicle (P = 0.02) and 71% of AN2898-treated lesions showed greater
improvement in ADSI score versus 14% for vehicle (P = 0.01). There were no severe adverse events reported that were considered related to either study drug.
In
June 2011, we reported results from the final Phase 2b trial to evaluate the safety and efficacy of AN2728 in patients with mild-to-moderate psoriasis
under the anticipated conditions of expected Phase 3 trials to provide preliminary indications of efficacy and local tolerability and systemic safety when treating all or nearly all of the
plaques on each subject. 68 subjects were randomized in a 2:1 ratio, AN2728 to vehicle. Subjects treated with AN2728 showed improvement over vehicle at each of the recorded timepoints during the
12-week study period with peak efficacy (defined by proportion of subjects achieving complete or near complete clearance of treated psoriasis plaques) of 26% occurring after six weeks of
treatment with AN2728.
In
October 2011 we held an End-of-Phase 2 meeting with the FDA to discuss the design of Phase 3 trials of AN2728 in psoriasis and, in November 2011,
we filed a SPA and reached agreement with the FDA on the major parameters associated with the design and conduct of the Phase 3 trials of AN2728 in psoriasis.
Given
the safety profile exhibited by AN2728 in 13 clinical studies, the positive outcome from the Phase 2a atopic dermatitis trial and the large unmet medical need in atopic
dermatitis relative to psoriasis, we intend to focus AN2728 development activities in 2012 on additional Phase 2 trials in atopic dermatitis and will defer the start of Phase 3 trials in
psoriasis.
AN2728 has demonstrated initial tolerability and activity against atopic dermatitis in one Phase 2a study, and against psoriatic
lesions in three Phase 1b, one Phase 2a, one Phase 2 and two Phase 2b clinical trials. For AN2728, all three of our completed Phase 1b microplaque trials showed
significant activity over vehicle. Subsequently, our four completed Phase 2 trials confirmed the results of the microplaque studies when applied by the patient.

We have completed a Phase 2a study of AN2728 and AN2898, our second topical anti-inflammatory, in atopic dermatitis.
In this multicenter, randomized, double-blind, vehicle-controlled, bilateral comparison study, 46 patients with mild-to-moderate dermatitis were randomized (1:1) to receive
either AN2728 Ointment, 2% vs. Ointment vehicle or AN2898 Ointment, 1% vs. Ointment vehicle, applied twice daily to two similar target lesions on the trunk or extremities for six weeks. Lesion
severity was measured by the ADSI score, which is the sum of the severity scores of five clinical features (erythema, pruritus, exudation, excoriation and lichenification) from 0 (none) to 3 (severe)
for each feature, for a total score of 0 to 15. The primary endpoint for both compounds was successfully achieved after 28 days of twice-daily treatment. In the final analysis, 68% of
AN2728-treated lesions showed greater improvement in ADSI score versus 20% for vehicle (P = 0.02) and 71% of AN2898-treated lesions showed greater improvement in ADSI
score versus 14% for vehicle (P = 0.01). There were no severe adverse events reported that were considered related to either study drug. In addition, lesions treated with AN2728 showed a 66%
mean improvement in ADSI score at day 28 compared to 39% mean improvement in ADSI score for lesions treated with vehicle (P < 0.01). Lesions treated with AN2898 showed a 68% mean
improvement in ADSI score at day 28 compared to 45% mean improvement in ADSI score for lesions treated with vehicle (P = 0.02). Finally, the proportion of lesions achieving total or partial
clearance (ADSI score
£
2.0) at day 28 was 52% for lesions treated with AN2728 compared to 16% for lesions treated with vehicle and 48% for lesions treated
with AN2898 compared to 33% for lesions treated with vehicle.
We have completed three Phase 1b clinical trials of AN2728. These trials utilized a microplaque design in which each patient had
small areas of a large psoriatic lesion treated with various medications for 12 days. Each of the treatment areas was evaluated at days one, eight and twelve. The primary endpoint for each of
these trials was the change in thickness of the psoriatic lesion as measured by sonography, and the secondary endpoint was improvement based on clinical score as evaluated by a physician. No
treatment-related adverse events were observed in these trials.

In March 2007, we completed our first Phase 1b microplaque clinical trial of AN2728 in patients with psoriasis. The study enrolled 12 patients for a
12-day treatment and compared AN2728 5.0% ointment, AN2728 5.0% cream, Betnesol-V cream (betamethasone valerate, a mid-potency corticosteroid) and Protopic ointment
(tacrolimus, an immunomodulator), vehicle cream and vehicle ointment. This study demonstrated that AN2728 caused a significant reduction in the thickness of psoriatic lesions compared to both
vehicles, at a P-value of 0.025. The mean percent reduction in infiltrate thickness for AN2728 was 54%, as compared to 48% for Protopic and 72% for Betnesol-V. The results of
the secondary endpoint paralleled the results of the primary endpoint.
In
December 2007, we completed our second Phase 1b microplaque clinical trial of AN2728 in patients with psoriasis. This study was a dose-ranging study designed to
compare 0.5%, 2.0% and 5.0% AN2728 ointment, Betnesol-V cream, Protopic, and the ointment vehicle. Based on the primary endpoint, which was the change in the thickness of the inflammatory
infiltrate, all three concentrations were significantly better than the ointment vehicle (P-values less than 0.003). The mean percent reductions for 5.0%, 2.0% and 0.5% AN2728 ointment
were 36%, 35%, and 26%, respectively. The percent reductions for Betnesol-V and Protopic were 59% and 34%, respectively.
In
March 2008, we completed our third Phase 1b microplaque trial in patients with psoriasis. This was a study designed to compare 0.3%, 1% and 2% AN2728, Betnesol-V
and vehicle. The
study enrolled 12 patients for a 12-day treatment. In the study, 1% and 2% AN2728 demonstrated significant improvement over vehicle and 0.3% AN2728 demonstrated a strong trend in
superiority over vehicle.
In
February 2012, we announced results for a Maximal Use Systemic Exposure (MUSE) study in psoriatic patients and a local tolerability study in healthy volunteers. The MUSE study was
designed to obtain a full pharmacokinetic profile in psoriatic patients under Phase 3 maximal use conditions. The multi-center, open label study enrolled 33 patients with extensive psoriasis
with a mean involvement of 38% of total body surface area. Patients applied AN2728 Ointment, 2% twice daily for eight days. No serious adverse events were reported and no subjects discontinued early
from the study. Application of AN2728 Ointment, 2% on larger body surface areas resulted in higher plasma exposure levels but did not correlate with greater adverse events. The local tolerability
study was designed to examine the potential irritancy of AN2728 Ointment, 2% when applied to sensitive skin areas such as the face, skin folds (groin, armpits), genitals, etc. This single-center,
double-blind, vehicle-controlled study randomized 32 adult healthy volunteers (3:1) to receive AN2728 Ointment, 2% or Ointment vehicle. Subjects applied study drug as instructed twice daily for
21 days to sensitive skin areas. At each of seven visits, each tolerability parameter was graded on a scale of 0 (none) to 3 (severe) in intervals of 0.5. Overall, almost 99% of the nearly
8,700 tolerability measurements were scored as 0 (none). None of the treated anatomic areas appeared to be particularly sensitive to irritation by the study drug or vehicle. No serious adverse events
were observed in the trial. Adverse events occurred at a low rate and were generally mild.
Psoriasis is often bilateral and symmetrical, meaning that patients with psoriasis commonly have similar areas of psoriasis on opposing
sides of their body. Three of our Phase 2 studies of AN2728 for the treatment of psoriasis were designed as bilateral studies in which patients treat one of their plaques with one treatment and
a similar plaque or the other side of the body with a comparison treatment. This allowed patients to serve as their own control.
In
March 2008, we completed a Phase 2a bilateral trial of AN2728 to characterize the safety profile and to assess efficacy. In this trial, patients, in a double-blinded fashion,
treated one of their areas of psoriasis with AN2728 5.0% ointment and a matching area on the opposite side of the body with the vehicle alone. The trial treated 35 patients with
mild-to-moderate psoriasis. The primary endpoint was the proportion of patients in whom the AN2728-treated area improved more than the
16
Table of Contents
vehicle-treated
area based on the overall target plaque severity score, or OTPSS. The OTPSS is a scoring system used by investigators that characterizes severity of disease, which ranges from zero (no
evidence of disease) to eight (very severe). Based on the OTPSS after four weeks, the trial achieved its primary endpoint, with 69% of the AN2728 treated plaques demonstrating a lower score than the
vehicle treated plaques as compared to 6% of the vehicle treated plaques (P-value less than 0.001). Significant differences were also noted after two weeks and three weeks and in all
secondary endpoints, including scaling, erythema and plaque elevation. In addition to no serious adverse events, there were no treatment-related adverse reactions or application site reactions.
In
December 2008, we completed a Phase 2 double-blind bilateral trial comparing 5.0% AN2728 ointment and vehicle using a design similar to our Phase 2a study but using a
longer treatment duration. In this Phase 2 study, patients with mild-to-moderate psoriasis applied AN2728 and vehicle twice daily for 12 weeks in order to define
the optimal duration of therapy. Results showed statistically significant reductions in the OTPSS, as well as in the individual signs of psoriasis, such as erythema, scale and plaque thickness at
several time points. Compared to those treated with vehicle, psoriasis plaques treated with AN2728 achieved a lower OTPSS in a significantly greater proportion of patients after as few as two weeks of
treatment, with optimal responses seen at six and eight weeks (P-value less than 0.001 and 0.01, respectively). Thirteen percent of the treated plaques cleared completely and 43% of the
plaques achieved clear or almost clear with a two-grade improvement from baseline. Treatments were generally well-tolerated with the most common side effect being irritation at
the application site. During the course of the trial, one serious adverse event was reported in a patient who developed a rash after receiving an injection of penicillin outside of the trial for a
sore throat and needed to be hospitalized for this non-life threatening reaction.
In
June 2010, we completed a 145-patient randomized, double-blind, vehicle-controlled, multicenter, Phase 2b bilateral dose-ranging trial to evaluate the
safety and efficacy of 0.5% and 2.0% AN2728 ointment, applied either once or twice daily for 12 weeks for the treatment of mild-to-moderate psoriasis. Compared to those
treated with vehicle, psoriasis plaques treated with AN2728 achieved greater improvement in the OTPSS in a significantly higher proportion of patients after six weeks in the 2.0% AN2728 twice daily
dosing group (P-value less than 0.001), which was the primary endpoint of the trial. A dose response was also observed across the four dosing groups for this outcome. Additionally, of
those plaques treated for 12 weeks with 2.0% AN2728 twice daily, 54% achieved complete or near complete clearance with at least a two-grade improvement from their baseline severity
score.
In
June 2011, we completed the final Phase 2b trial to evaluate the safety and efficacy of AN2728 in patients with mild-to-moderate psoriasis under the
anticipated conditions of expected Phase 3 trials to provide preliminary indications of efficacy and local tolerability and systemic safety when treating all or nearly all of the plaques on
each subject. 68 subjects were randomized in a 2:1 ratio, AN2728 to vehicle. Subjects treated with AN2728 showed improvement over vehicle at each of the recorded timepoints during the
12-week study period with peak
efficacy (defined by proportion of subjects achieving complete or near complete clearance of treated psoriasis plaques) of 26% occurring after six weeks of treatment with AN2728.
AN2898 is our second anti-inflammatory product candidate for atopic dermatitis and psoriasis. Like AN2728, AN2898 is a
novel boron-containing small molecule that inhibits PDE-4 and reduces the production of pro-inflammatory cytokines believed to be associated with atopic dermatitis and psoriasis.
In
February 2009, we initiated a Phase 1b study evaluating AN2898 in 12 patients with plaque-type psoriasis for 12 days. This was a microplaque study conducted
in a similar fashion as the AN2728 microplaque trials. Achieving its primary endpoint, this study demonstrated that AN2898 caused a
17
Table of Contents
significant
reduction in the thickness of psoriatic lesions compared to vehicle, at a P-value less than 0.0001. The mean percent reduction in infiltrate thickness on day 12 for AN2898 was
39%, as compared to 60% for Betnesol-V, the positive control. The results relative to the secondary endpoint (clinical response) paralleled those of the primary endpoint.
In
a cumulative irritation trial completed in the first quarter of 2009, AN2898 ointment at 5.0% and its vehicle were applied daily to the skin of normal volunteers under occlusive,
adhesive patches for four consecutive days. Application sites were evaluated daily for signs of irritation. No irritation potential was seen for 5.0% AN2898 ointment or the vehicle.
In
December 2011, we completed a Phase 2a study of AN2898 in atopic dermatitis. In this multicenter, randomized, double-blind, vehicle-controlled, bilateral comparison study, 46
patients with mild-to-moderate dermatitis were randomized (1:1) to receive either AN2728 Ointment, 2% vs. Ointment vehicle or AN2898 Ointment, 1% vs. Ointment vehicle, applied
twice daily to two similar target lesions on the trunk or extremities for six weeks. The primary endpoint for both compounds was successfully achieved after 28 days of twice-daily treatment.
Our Systemic Antibiotic Program
GSK '052 is our lead systemic antibiotic product candidate for the treatment of infections caused by Gram-negative
bacteria. In July 2010, GSK exercised its option to obtain an exclusive license to develop and commercialize GSK '052. GSK has assumed responsibility for further development of the product candidate
and any resulting commercialization. In June 2011, GSK initiated two Phase 2b trials for cUTI and cIAI. In March 2012, GSK voluntarily discontinued certain of its current clinical trials of GSK
'052 due to a recently identified microbiological finding in a small number of patients in the Phase 2b trial of GSK '052 for the treatment of cUTI. While we believe the microbiological finding
seen in the cUTI study is not related to the safety of GSK '052, the potential to negatively impact efficacy led GSK to voluntarily discontinue that study as well as the Phase 2b study in cIAI
and one of two Phase 1 studies in healthy volunteers. GSK is in the process of obtaining and analyzing additional information from all enrolled subjects. Upon completion of this analysis, GSK
will consider options for the future development of GSK '052.
Gram-negative infections are a type of bacterial infection caused by a broad class of bacteria called
Gram-negative bacteria and are most commonly acquired and treated in the hospital setting. Many commonly used antibiotics do not work against Gram-negative bacteria and
resistance to existing therapies continues to be a growing problem. According to the
New England Journal of Medicine
, it is estimated that there were
1.7 million hospital-acquired Gram-negative and Gram-positive infections and approximately 100,000 associated deaths in the United States alone in 2002. The
New England Journal of Medicine
also
indicates that Gram-negative bacteria are responsible for more than 30.0% of hospital-acquired
infections and account for approximately 70.0% of hospital-acquired infections in the intensive care unit. IMS Health estimates that there were 40 million days of Gram-negative
therapy administered in the United States in 2009. According to the
Archives of Internal Medicine
, hospital-acquired infections related to sepsis and
pneumonia alone caused $8.1 billion in additional hospital costs in 2006.
Traditionally, Gram-negative infections have been treated with antibiotics, particularly beta-lactams,
including penicillins, cephalosporins and carbapenems, and quinolones, including flouroquinolones. However, the effectiveness of existing antibiotics has been declining due to increasingly prevalent
drug resistance. Bacteria develop resistance to drugs through genetic mutations or by acquiring genes from
18
Table of Contents
other
bacteria that have become resistant. For example, in a recent survey of resistance rates of Gram-negative bacteria to current therapies in the United States, the resistance of
E. coli
to
fluoroquinolones has been dramatically increasing. For example, resistance of
E. coli
to
ciprofloxacin increased from 4% in 1999 to 30% in 2008 and resistance of
E. coli
to levofloxacin increased from 10% in 2003 to 30% in 2008. Over the
same period, resistance of another Gram-negative bacteria,
Klebsiella pneumoniae
, to third generation cephalosporins, such as ceftriaxone
and ceftazidime, increased from virtually no resistance to 15%. The same survey also showed that by 2008, 17%-19% of
Pseudomonas aeruginosa
were resistant to fluoroquinolones, 10%-70% were resistant to third generation cephalosporins and 7%-15% were resistant to carbapenems, such as meropenem and imipenem.
Therefore, there is an ongoing need for novel antibiotics to combat the widespread proliferation of antibiotic resistance, particularly for Gram-negative bacteria. Additionally, currently
marketed products have side effect profiles that can include nausea, diarrhea, vomiting, rash, insomnia, and potential liver toxicity. Also, currently approved antibiotics specifically targeting
infections caused by Gram-negative bacteria are only available in either IV or oral formulations, but not both, so patients cannot continue on the same antibiotic therapy they received in
the hospital once they are discharged.
GSK '052 is a novel boron-based, small molecule product candidate that targets the bacterial enzyme leucyl tRNA synthetase. The
inhibition of protein synthesis leads to termination of cell growth and cell death, eliminating the bacterial infection. Preclinical studies suggest that GSK '052 could be a novel approach for the
treatment of infections caused by Gram-negative bacteria, including
E. coli
,
Klebsiella
pneumoniae
,
Citrobacter spp.
,
S. marcescens
,
P.
vulgaris
,
Providentia spp.
,
Pseudomonas aeruginosa
and
Enterobacter spp.
GSK '052
has demonstrated a favorable profile in preclinical safety and toxicology studies. Results from a Phase 1
proof-of-concept trial showed that GSK '052 demonstrated a promising
safety profile and linear dose-proportional pharmacokinetic properties, reaching blood levels that were multiple times higher than the anticipated efficacious dose. Subject to GSK's
decision to continue further development, we believe GSK '052 could represent the first new class antibacterial to treat serious hospital-acquired Gram-negative infections in thirty years.
In addition, we believe GSK '052 has the potential to be the first antibiotic specifically targeting infections caused by Gram-negative bacteria that can be administered by both IV and
oral routes, which, for the first time, would allow patients to continue on the same antibiotic therapy they received in the hospital once they are discharged.
In November 2009, we initiated a Phase 1 dose-escalating clinical study for GSK '052, to evaluate the safety,
tolerability and pharmacokinetics of GSK '052 in healthy volunteers. The randomized, double-blind, placebo-controlled, dose-escalation study enrolled 72 subjects. Participants in this
study received GSK '052 in single or multiple doses for treatment durations of up to 14 days and included doses that achieve blood levels that are approximately four times the expected
efficacious blood levels based on our preclinical studies. In June 2010, we reported Phase 1 results showing that GSK '052 appeared to be safe and well-tolerated. In July 2010, GSK
exercised its option to obtain an exclusive license to develop and commercialize GSK '052. Upon exercise of the option, we received a fee of $15.0 million. In June 2011, GSK initiated two
Phase 2b trials for cUTI and cIAI. In September 2011, GSK was awarded a $94 million contract with the U.S. Department of Health and Human Services' Biomedical Advanced Research and
Development Authority, or BARDA, to support the ongoing development of GSK '052 including studies to evaluate the efficacy of GSK '052 against bioterrorism threats, Phase 2 clinical trials for
ventilator-associated pneumonia, and Phase 3 trials for complicated intra-abdominal infections.

In
March 2012, GSK voluntarily discontinued certain of its current clinical trials of GSK '052 due to a recently identified microbiological finding in a small number of patients in the
Phase 2b trial of GSK '052 for the treatment of cUTI. While we believe the microbiological finding seen in the cUTI study is not related to the safety of GSK '052, the potential to negatively
impact efficacy led GSK to voluntarily discontinue that study as well as the Phase 2b study in cIAI and one of two Phase 1 studies in healthy volunteers. GSK is in the process of
obtaining and analyzing additional information from all enrolled subjects. Upon completion of this analysis, GSK will consider options for the future development of GSK '052.
Our Animal Health Program
AN8194 is a boron-based compound currently in development for an undisclosed indication in animal health. In August 2010, we
established a research and development agreement with Lilly to create and develop new therapeutics for animal health. In August, 2011, Lilly selected AN8194 as its first development candidate for
which we received a $1 million milestone payment.
The animal health market is focused on providing a quality life to animals that are generally categorized as companion animals or food
animals. The market is driven primarily by two main factors: pet owners in the United States and Europe demanding more advanced and expensive treatments for companion animals, and the growing world
population has increased the demand for food animals requiring improvements in livestock health care and feeding in food animal production. Pharmaceutical products in animal health include vaccines,
antibiotics, antifungals, anti-parasitics and medical feed additives. The market for animal health products is approximately $20 billion a year with an annual growth rate averaging
over 6% in the last 10 years. The top-selling animal health products are anti-parasitics for companion animals and generate annual sales of almost a $1 billion a
year.
Our boron chemistry platform has demonstrated the potential to treat a number of diseases caused by bacteria, fungi and parasites, some
of the leading causes of diseases in animals. As a result of some of our work in human neglected diseases, we identified the opportunity to address unmet medical needs in animals as well. Lilly funded
the research that resulted in the discovery of AN8194 and will be responsible for its future development and commercialization. Anacor is eligible
to receive additional development and regulatory milestones as well as tiered royalties from the high single digits to low double digits on future sales.
Our Neglected Diseases Initiatives
AN5568 is a boron-based compound currently in Phase 1 clinical trials for sleeping sickness. In December 2007, we established a
partnership with DNDi to develop new therapeutics for sleeping sickness, visceral leishmaniasis and Chagas disease. In March 2012, DNDi commenced Phase 1 human clinical trials of AN5568 in
sleeping sickness. AN5568 is a product of Anacor's boron chemistry and the first oral drug candidate for this indication.
Sleeping sickness threatens millions in 36 countries in sub-Saharan Africa and is fatal if left untreated. The disease is
caused by parasites transmitted by the bite of a tsetse fly and is often asymptomatic for years until the infection reaches "stage 2" where it crosses into the central nervous system and brain.
Without effective treatment, sleeping sickness is fatal.
20

Currently available treatments are limited to drugs developed decades ago that are either highly toxic, difficult to administer in
resource-limited settings, or are only effective in one stage of the disease. In addition, prior to being treated, the stage of the disease must be determined using a diagnostic spinal tap to extract
cerebrospinal fluid from the patient. Two-thirds of all reported sleeping sickness cases are found in the Democratic Republic of the Congo (DRC), where healthcare is often inaccessible to
large parts of the population due to violent conflict, great distances patients must travel to health facilities, and extreme poverty.
In pre-clinical studies, AN5568 demonstrated safety and the ability to cross the blood-brain barrier making it efficacious
against stage 1 and stage 2 of the disease. In addition, its oral formulation, short duration of therapy and excellent pre-clinical safety profile imply that it could change
the way sleeping sickness is treated, reduce its incidence in humans, and contribute to elimination of the disease.
Research Activities
Our internal research activities include follow-on research to our existing compounds as well as investigation of novel
activity of our boron chemistry platform in multiple therapeutic applications. Key efforts currently include the further development of topical and systemic PDE-4 inhibitors for the treatment of
inflammatory diseases, the development of novel anti-infectives against targets not covered in our existing GSK collaboration, and work on novel kinase inhibitors.
Neglected diseases are defined as diseases that disproportionately affect the world's poorest people, including tuberculosis, or TB,
malaria, visceral leishmaniasis, Chagas disease, sleeping sickness, and filarial worms. Despite the fact that these diseases cause significant morbidity and mortality worldwide, and that the current
standards of care are difficult to administer, have significant toxicities and are increasingly becoming less effective due to resistance, there has been little investment in developing new therapies
for these diseases due to the absence of a reasonable expectation of a financial return.
Our
boron chemistry platform appears to be particularly well suited for the treatment of these types of infectious diseases, and we feel a responsibility to apply our technology to the
development of new treatments. Until such time as we are profitable, however, we are committed to doing that research only when we can use grants and other non-dilutive sources of funding
in a cash-neutral manner.
In
recent years, a number of foundations and governments have created public- private partnerships to address this gap by funding promising technologies that may result in new drugs. In
December 2007, we established a partnership with the DNDi to develop new therapeutics for sleeping sickness, visceral leishmaniasis and Chagas disease. In March 2012, DNDi initiated the first
Phase 1 clinical trial of AN5568 in humans for sleeping sickness. In May 2009, we established a collaboration with the Global Alliance for TB Drug Development. In April 2010, we entered into a
research collaboration with the MMV to identify lead compounds for the treatment of prophylaxis of malaria and in March 2011 we also entered into a development agreement with MMV to develop compounds
for the treatment of malaria. In December 2010, we entered into a collaboration with the Sandler Center for Drug Discovery at the University of California at San Francisco to discover new drug
therapies for the treatment of river blindness, a parasitic disease that is the second leading cause of
21
Table of Contents
infectious
blindness worldwide. In March 2011, we announced the establishment of our joint research agreement with the Institute for OneWorld Health to discover antibacterial compounds for treating
diarrheal diseases.
Our
work in this area also allows us the potential benefits of expanding the chemical diversity of our boron compounds, understanding new properties of our boron compounds, receiving
future incentives, such as the potential grant of a priority review voucher by the FDA, and, ultimately if a drug is approved, potential revenue in some regions.
Collaboration with GSK
In October 2007, we entered into a research and development collaboration, option and license agreement with GSK for the discovery,
development and worldwide commercialization of boron-based systemic anti-infectives. Under the agreement, we are currently working to identify and develop product candidates in three
target-based project areas. The collaborative research term of the agreement is six years, subject to an extension of up to two years if agreed to by both parties.
Pursuant
to the agreement, GSK paid us a $12.0 million non-refundable, non-creditable upfront fee in October 2007. In addition, GSK invested
$30.0 million in a preferred stock financing completed in December 2008. Subsequently, in November 2010, GSK invested an additional $5.0 million in our common stock in connection with
our initial public offering.
In
July 2010, GSK exercised its option to obtain an exclusive license to develop and commercialize GSK '052 (formerly known as AN3365), our lead systemic antibiotic for the treatment of
infections caused by Gram-negative bacteria. Upon exercise of the option, we received a licensing fee of $15.0 million. GSK assumed responsibility for further development of the
product candidate and any resulting commercialization. In June 2011, GSK initiated two Phase 2b trials for complicated urinary tract infections and complicated intra-abdominal infections. In
March 2012, GSK voluntarily discontinued certain of its current clinical trials of GSK '052 due to a recently identified microbiological finding in a small number of patients in the Phase 2b
trial of GSK '052 for the treatment of cUTI. While we believe the microbiological finding seen in the cUTI study is not related to the safety of GSK '052, the potential to negatively impact efficacy
led GSK to voluntarily discontinue that study as well as the Phase 2b study in cIAI and one of two Phase 1 studies in healthy volunteers. GSK is in the process of obtaining and analyzing
additional information from all enrolled subjects. Upon completion of this analysis, GSK will consider options for the future development of GSK '052. Pending continued development of GSK '052, we
would be eligible to receive potential development milestones up to $75.0 million, commercial milestones up to $175.0 million and double-digit tiered royalties with the potential to
reach the mid-teens on annual net sales.
In
September 2011, we amended and expanded our agreement with GSK and received a $5.0 million upfront payment. The amended agreement provides an option for GSK to expand its
rights around the bacterial enzyme target LeuRS in return for a milestone payment ranging from $5.5 million to $6.5 million, depending upon the timing of such payment. Any future work
under the collaboration directed towards LeuRS will be funded by GSK through a collaborative research program under which Anacor and GSK would pursue additional drug candidates to candidate selection,
following which, GSK would have the right to undertake further development and commercialization. Anacor would be eligible for additional milestones, which range from up to $189.4 million to
$264.0 million in the aggregate per product candidate, and royalties in the high single digits on sales of resulting products. In addition, the amendment to the collaboration adds a new program
for TB, under which GSK will fund Anacor's TB research activities through to candidate selection. Upon meeting candidate selection
criteria, GSK will have the option to license TB compounds and would be responsible for all further development and commercialization. Anacor would be eligible for additional milestones and royalties
on sales of resulting products. The amendment also includes the option for GSK to acquire rights to
22
Table of Contents
Anacor's
malaria program, currently being developed through a collaboration with MMV. Anacor and MMV will continue to conduct preclinical, Phase 1 and Phase 2 proof of concept studies,
and GSK will have the option to license the program on an exclusive worldwide basis upon achieving Phase 2 proof of concept. Upon exercise of this option, Anacor would receive
$5 million, less $1.7 million that will be paid to MMV as reimbursement for previously received funding and that will be reinvested in future anti-malarial research. Anacor
would also be eligible for additional milestones and royalties on sales of resulting products. GSK is obligated to pay us tiered royalties with on annual net sales of products containing licensed
compounds in jurisdictions where there is a valid patent claim covering composition of matter or method of use of the product and lesser royalties for sales in jurisdictions where there is no such
valid patent claim. Such royalties shall continue until the later of expiration of such valid patent claims or ten years from the first commercial sale on a product-by-product
and country-by-country basis.
To
date, in addition to the $17.0 million upfront payments and $15.0 million option exercise fee, we have received $10.1 million for achievement of performance
milestones, including GSK '052 milestones for lead declaration, candidate selection and first patient dosing in a Phase 1 clinical trial. We have also received milestone payments for lead
declarations in two other GSK programs.
The
agreement provides for a joint research committee to oversee the research collaboration, and a joint patent subcommittee responsible for coordination of intellectual property
developed by the collaboration, including patent application filing. We and GSK have appointed an equal number of members to each such committee and decisions are made on a consensus basis, except
that ultimate decision-making authority with respect to determining whether candidate selection criteria have been met, is vested in GSK. Unless earlier terminated, the agreement will continue in
effect until expiration of all payment obligations under the agreement. GSK retains the unilateral right to terminate the agreement in its entirety upon six months prior written notice to us and
immediately with respect to any project. Either party may also terminate the agreement, on a project-by-project basis or in its entirety, for any uncured material breach of the
agreement by the other party. Either party may also terminate the agreement upon specified actions relating to insolvency of the other party. In the event of unilateral termination by GSK, all rights
granted by us to GSK with respect to the project to which such termination applies would terminate and we would retain the rights to any compounds relating to such project. In the event of termination
by GSK for cause, GSK would have a perpetual exclusive license under our intellectual property to develop and commercialize any project compounds to which such termination applies, subject to GSK's
payment to us of specified royalties on sales of such compounds. In the event of termination by us for cause, we would have a perpetual exclusive license under GSK's intellectual
property to develop and commercialize any project compound to which such termination applies, subject to payment by us to GSK of specified royalties on sales of such compounds.
For
a specified period following the effective date of the agreement, subject to certain exceptions, we may not research, optimize, develop or commercialize outside of the collaboration
any compounds that we progressed through the project, or any other compounds directed against the same target, unless GSK's option to such compound terminated without being exercised or GSK later
terminates its license to such compound after exercising such option. If we choose to develop such compounds after expiration of GSK's option or termination of GSK's license, we may be required under
certain circumstances to make certain regulatory milestone and royalty payments to GSK for such compounds.
Upon
a change of control of either party, the agreement would remain in effect. Upon a change of control of Anacor, GSK has the right to elect to exercise any remaining options to
license and commercialize compounds then under development pursuant to the research collaboration.

Collaboration with Eli Lilly and Company
In August 2010, we entered into a research agreement with Eli Lilly and Company, or Lilly, under which we will collaborate to discover
products for a variety of animal health applications and Lilly will be responsible for worldwide development and commercialization of compounds advancing from these efforts. The collaboration combines
our boron-based technology platform and drug research capabilities with Lilly's expertise in the area of animal health. We received an upfront payment of $3.5 million and we will receive a
minimum of $6.0 million in research funding with the potential of up to $12.0 million in research funding, if successful. In August 2011, we achieved our first development candidate in
animal health under this collaboration and received a $1.0 million milestone payment. In addition, we will be eligible to receive payments upon the achievement of development and regulatory
milestones, as well as tiered royalties, escalating from high single digit to in the tens, on sales depending in part upon the mix of products sold. Such royalties continue through the later of
expiration of our patent rights or six years from the first commercial sale on a product-by-product and country-by-country basis.
Unless
earlier terminated, the agreement continues in effect until the termination of royalty payment obligations. The agreement allows for termination by Lilly upon written notice, with
certain additional payments to us and a notice period that has a duration dependent on whether the notice is delivered
prior to the first regulatory approval of a product under the agreement or thereafter. In addition, either party may terminate for the other party's uncured material breach of the agreement. In the
event of termination by us for material breach by Lilly or termination upon written notice by Lilly, Lilly would assign to us certain trademarks and regulatory materials used in connection with the
products under the agreement and grant to us an exclusive license under Lilly's patent rights covering such products, and we would pay to Lilly a reasonable royalty on sales of such products should we
desire an exclusive license. In the event of termination for material breach by us, Lilly will be entitled to a return of all research funding payments for expenses we have not incurred or irrevocably
committed.
Collaboration with Medicis
In February 2011, we entered into a research and development option and license agreement with Medicis to discover and develop
boron-based small molecule compounds directed against a target for the potential treatment of acne.
Under
the terms of the agreement, we received a $7.0 million upfront payment from Medicis and will be primarily responsible, during a defined research collaboration term, for
discovering and conducting early development of product candidates which utilize our proprietary boron chemistry platform. Medicis will have an option to obtain an exclusive license for products
covered by the agreement. We will be eligible for future research, development, regulatory and sales milestones of up to $153.0 million, as well as high single-digit to in the tens royalties on
sales of products that Medicis licenses pursuant to its option. Following option exercise, Medicis will be responsible for further development and commercialization of the licensed products on a
worldwide basis.
If
Medicis exercises its option for a product candidate, the agreement will continue in effect until the expiration of royalty payment obligations, which obligations will run through the
later of patent or regulatory exclusivity and 7 years from first commercial sale, on a product-by-product basis. Upon the expiration of such payment obligations for a
product under the agreement, Medicis will retain an exclusive, fully paid and royalty-free right and license in such product. The agreement allows for at-will termination by
Medicis upon written notice, and either party may terminate for the other party's uncured material breach of the agreement or specified activities related to insolvency. In the event of
at-will termination by Medicis or termination by us for material breach or insolvency activities by Medicis, all rights granted by us to Medicis would revert to us, and Medicis would be
required to grant to us a non-exclusive license under its patent rights covering products under the agreement. If we
24
Table of Contents
materially
breach the agreement prior to the completion of the research collaboration term and exercise of the option, Medicis would be entitled to either terminate the agreement or continue with the
agreement and terminate the research collaboration term, in which case Medicis would have a right to reduce its financial obligations to us or recover its costs to mitigate the damages resulting from
such breach.
We
have agreed not to research or develop, with respect to the target that is the subject of the agreement, any small molecule products in a specified field for use in humans for a
period of 11 years. Medicis has agreed not to research or develop with respect to the target that is the subject of the agreement any boron-containing compound for 9 years from the date
of the agreement or, if a certain milestone is not met, for 4 years from the date of the agreement.
Sales and Marketing
Our strategy is to develop a sales force targeting dermatologists and other specialty markets in the United States and to collaborate
with other companies for sales into primary care markets. In addition, we plan to enter into agreements with third parties to commercialize our products outside of the United States.
We
expect that if tavaborole and AN2718 are approved, primary care physicians will write a significant portion of prescriptions for these compounds in the United States, and we expect
half of overall sales will be within the United States. Accordingly, we plan to enter into a partnership for tavaborole after the completion of Phase 3 clinical trials. We also anticipate that,
if tavaborole, AN2718, AN2728 and AN2898 are approved, dermatologists and podiatrists will write a significant number of tavaborole and AN2718 prescriptions, and dermatologists will write a majority
of prescriptions for AN2728 and AN2898, which we expect to address with our own sales force in the United States. If AN2728 and AN2898 are approved, we intend to sell these products for atopic
dermatitis and psoriasis to dermatologists in the United States, and license commercialization rights to these product candidates to third parties for sales outside of the United States.
Intellectual Property
Previous efforts to produce boron-based drugs have been centered largely on boronic acids as serine protease inhibitors, such as the
oncology treatment Velcade. Our research concentrates on different biological targets and uses novel boron-based compounds where we believe there is little existing intellectual property held by
others. Some of our intellectual property related to our product candidates was initially developed by us or our subcontractors. In the course of our development and commercialization collaborations,
intellectual property relating to our product candidates may be developed by us and/or our collaborators, such as GSK, Lilly or Medicis.
As
of February 1, 2012, we were the owner of record of 12 issued U.S. patents (U.S. Pat. No. 7,390,806; U.S. Pat. No. 7,888,356; U.S. Pat. No. 7,652,000; U.S.
Pat. No. 7,465,836; U.S. Pat. No. 7,968,752; U.S. Pat. No. 8,106,031; U.S. Pat. No. 7,582,621; U.S. Pat. No. 7,767,657; U.S. Pat. No. 8,039,451; U.S. Pat.
No. 7,816,344; and U.S. Pat. No. 8,039,450) and 7 non-U.S. patents (2 South African patents, 2 Australian patents, 2 New Zealand patents, and 1 Russian patent). We are
actively pursuing, either solely or with a collaborator, 32 U.S. patent applications 12 provisional and 20 non-provisional), 13 international (PCT) patent applications and 140
non-U.S. patent applications in at least 39 jurisdictions, including Australia, Brazil, Canada, China, Europe, Hong Kong, India, Israel, Japan, Mexico, New Zealand, Russia, South Africa,
and South Korea. Of these actively pursued applications, 1 international (PCT) patent application and 3 non-U.S. patent applications are solely owned by a collaborator as of
February 1, 2012.
Our
patent filings seek to protect innovations created by us and/or our collaborators, such as composition of matter (compound or pharmaceutical formulation), method of use, and process
of

production.
As of February 1, 2012, claims have issued in the United States (U.S. Pat. No. 7,582,621 and U.S. Pat. No. 7,767,657), Australia, New Zealand, South Africa, and Russia
which cover, among other embodiments, methods of using tavaborole to treat onychomycosis as well as pharmaceutical formulations containing tavaborole. As of February 1, 2012, claims have issued
in Australia, New Zealand, South Africa, and Russia that cover, among other embodiments, methods of using AN2718 to treat onychomycosis as well as pharmaceutical formulations containing AN2718. Due to
the existence of an expired U.S. patent relating to a non-pharmaceutical use of the compounds, we are not pursuing a claim solely covering tavaborole or AN2718 as a compound. As of
February 1, 2012, claims have issued in the United States (U.S. Pat. No. 8,039,451) and Australia which cover, among other embodiments, AN2728 as a compound as well as pharmaceutical
formulations containing AN2728. As of February 1, 2012, claims have issued in Australia which cover, among other embodiments, AN2898 as a compound as well as pharmaceutical formulations
containing AN2898. U.S. Pat. No. 7,816,344 claims GSK '052 as a compound as well as part of a pharmaceutical formulation. U.S.
Pat. No. 7,390,806, U.S. Pat. No. 7,465,836, U.S. Pat. No. 7,968,752, U.S. Pat. No. 8,106,031, and U.S. Pat. No. 8,039,450 claim compounds which do not relate to our
current product candidates. U.S. Pat. No. 7,465,836, U.S. Pat. No. 7,888,356, and U.S. Pat. No. 8,039,450 claim pharmaceutical formulations that do not relate to our current
product candidates. U.S. Pat. No. 7,465,836, U.S. Pat. No. 7,652,000, U.S. Pat. No. 7,888,356, and U.S. Pat. No. 7,968,752 claim methods of using compounds which do not
relate to our current product candidates.
Our
agreement with GSK provides that we will retain all of our right, title and interest in intellectual property for which we possess the right to license or sublicense as of the
effective date of the agreement and throughout the term of the agreement. Each party will remain the sole owner of intellectual property developed by its personnel under the research collaboration.
Intellectual property that is jointly developed by GSK and us under the collaboration will be jointly owned by GSK and us, subject to exclusive licenses that may be granted to GSK or us pursuant to
the terms of the agreement.
Our
agreement with Lilly provides that we will retain all of our right, title and interest in intellectual property for which we possess the right to license or sublicense as of the
effective date of the agreement and throughout the term of the agreement. Each party will remain the sole owner of intellectual property developed by its personnel under the research collaboration.
Intellectual property that is jointly developed by Lilly and us under the collaboration will be jointly owned by Lilly and us, subject to exclusive licenses that may be granted to Lilly or us pursuant
to the terms of the agreement.
Our
agreement with Medicis provides that we will retain all of our right, title and interest in intellectual property for which we possess the right to license or sublicense as of the
effective date of the agreement and throughout the term of the agreement. Each party will remain the sole owner of intellectual property developed by its personnel under the research collaboration.
Intellectual property that is jointly developed by Medicis and us under the collaboration will, under certain circumstances, be jointly owned by Medicis and us, subject to exclusive licenses that may
be granted to Medicis or us pursuant to the terms of the agreement.
Our
commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection of our current and future product candidates and the methods used to
manufacture them, as well as successfully defending these patents against third-party challenges. Our ability to stop third parties from making, using, selling, offering to sell or importing our
products depends on the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities. There can be no assurance that our pending patent applications
will result in issued patents.

Manufacturing and Supply
Our current product candidates are low molecular weight molecules that are synthesized chemically and, therefore, we believe they are
easier to manufacture at relatively lower cost than biologic drugs from cell-based sources. All of our current clinical drug product manufacturing activities are in compliance with current
Good Manufacturing Practices, or cGMP, and are outsourced to qualified third parties with oversight by our employees. We have limited in-house, non-GMP manufacturing capacity
for research activities. We rely on third-party cGMP manufacturers for scale-up of the active ingredient, process development work and to produce sufficient quantities of product
candidates for use in clinical trials. We intend to continue to rely on third-party cGMP manufacturers for any future clinical trials and large-scale commercialization of all of our compounds for
which we have manufacturing responsibility. We have established multiple sources of supply for the reagents necessary for the manufacture of our compounds. We believe this manufacturing strategy will
enable us to direct financial resources to the development and commercialization of products rather than diverting resources to establishing a manufacturing infrastructure.
Prior
to entering into the agreement with Schering in 2007, we had successfully outsourced tavaborole cGMP manufacturing to a contract manufacturer at a scale that would have been
sufficient to conduct
Phase 3 clinical trials. Under our agreement with Schering, the formulation for tavaborole was finalized and manufactured at one of Schering's GMP facilities. In November 2009, Schering merged
with Merck and in May 2010, we regained the worldwide rights to tavaborole. As part of the transition from Merck to us, we received sufficient drug product to initiate and sufficient active ingredient
to complete our planned Phase 3 clinical trials of tavaborole. We have transferred tavaborole drug product manufacturing to a third party that operates in compliance with cGMP regulations and
will need to scale up and manufacture additional active ingredient and drug product, potentially at other third party manufacturing sites, in order to complete our NDA submission. We outsource global
process development work and product manufacturing to third parties for AN2728 and our other product candidates.
Competition
If approved for the treatment of onychomycosis, we anticipate tavaborole and AN2718 would compete with other approved onychomycosis
therapeutics including:
-
-
Systemic treatments:
Lamisil, also known by its generic
name, terbinafine, is marketed by Novartis. Terbinafine is available from several generic manufacturers. Sporanox, also known by its generic name, itraconazole, is marketed by Johnson & Johnson
and is available as a generic as well.
-
-
Topical treatments:
Penlac, also known by its generic
name, ciclopirox, is marketed by sanofi-aventis. Several versions of ciclopirox are available as generics.
In
addition to approved onychomycosis therapeutics, the marketing of several over-the-counter products is directed toward persons suffering from onychomycosis,
even though none of these products is FDA-approved for onychomycosis treatment.
There
are also several pharmaceutical product candidates under development that could potentially be used to treat onychomycosis and compete with tavaborole. Product candidates in
late-stage development include a novel topical triazole that completed Phase 3 development in December 2011 and was developed by Dow Pharmaceutical Sciences, or DPS, a wholly-owned
subsidiary of Valeant Pharmaceuticals International, an undisclosed topical product candidate in Phase 3 development by Promius Pharma, LLC, a wholly-owned subsidiary of
Dr. Reddy's Laboratories, and a topical reformulation of terbinafine in Phase 3 development by Celtic Pharma Management L.P. There are also
27
Table of Contents
several
companies pursuing various devices for onychomycosis, including laser technology. At least three lasers have received FDA clearance for the treatment of onychomycosisthe PinPointe
FootLaser, Cutera's GenesisPlus and the JOULE ClearSense laser system. In addition, there are a number of earlier stage therapeutics and devices in various stages of development for the treatment of
onychomycosis.
If approved for the treatment of atopic dermatitis, we anticipate AN2728 would compete with other marketed atopic dermatitis
therapeutics. Current atopic dermatitis treatments attempt to reduce inflammation and itchiness to maintain the protective integrity of the skin. Combinations of antibiotics, antihistamines, topical
corticosteroids and topical immunomodulators, such as Elidel (pimecrolimus) and Protopic (tacrolimus), are the current standard of care. In addition, while the use of ultraviolet light is not approved
by the FDA, it has been applied to the treatment of atopic dermatitis.
If approved for the treatment of psoriasis, we anticipate AN2728 would compete with other marketed psoriasis therapeutics
including:
-
-
Prescription topical treatments:
Several branded products
exist for the topical treatment of mild-to-moderate psoriasis. Taclonex, a combination of calcipotriene and the high potency corticosteroid betamethasone dipropionate, and
Dovonex, also known by its generic name, calcipotriene, are currently marketed by LEO Pharma. Tazorac, also known by its generic name, tazarotene, is currently marketed by Allergan. Vectical, also
known by its generic name, calcitriol, is currently marketed by Galderma. Generic products for the treatment of mild-to-moderate psoriasis include corticosteroids, such as
triamcinolone and betamethasone, as well as the natural product derivative anthralin.
-
-
Systemic treatments:
Among the product prescribed for the
treatment of moderate-to-severe psoriasis are the following: oral products, such as methotrexate, cyclosporine and acitretin; injected biologic products, such as Enbrel,
marketed by Amgen, Remicade, Stelara and Simponi, marketed by Janssen Biotech, Amevive, marketed by Astellas, and Humira, marketed by Abbott.
-
-
Other treatments:
Various light-based treatments are also
used to treat psoriasis, including the 380 nanometer excimer laser and pulsed dye lasers. In addition, there are several non-prescription or over-the-counter
topical treatments utilized to treat psoriasis, including salicylic acid and coal tar, as well as bath solutions and moisturizers.
In
addition to the marketed psoriasis therapeutics, there are product candidates in Phase 3 development that could potentially be used to treat psoriasis and compete with AN2728,
including an injectable therapy from Abbott, and oral therapies from Pfizer, Celgene and Isotechnika. In addition to these, a number of topical, oral and injectable product candidates are in various
stages of development for the treatment of psoriasis.
If approved for the treatment of infections caused by Gram-negative bacteria, we anticipate GSK '052 would compete with
other marketed broad spectrum and Gram-negative antibiotics.
-
-
Marketed antibiotics:
There are a variety of marketed
broad spectrum as well as Gram-negative antibiotics targeting Gram-negative infections. Current marketed products for Gram-negative infections include
piperacillin/tazobactam (Pfizer's Zosyn/Tazocin), imipenem/cilastatin (Merck's Primaxin/Tienam), meropenem (Cubist Pharmaceuticals/AstraZeneca's Merrem/Meronem), levofloxacin (Johnson &
Johnson's Levaquin, sanofi-aventis's Tavanic and Daiichi Sankyo's
28
Table of Contents
Cravit)
and ciprofloxacin, or cipro, marketed under multiple brand names. Next-generation cephalosporins, carbapenems, quinolones and beta-lactam/beta-lactamase
inhibitors, such as Johnson & Johnson's Doribax and Pfizer's Tygacil, are expected to capture significant market share.
-
-
Antibiotics in development:
The need for new antibiotics
will continue to grow due to evolving resistance to existing antibiotics. There are several earlier stage compounds in clinical development including Forest and AstraZeneca's
ceftazidime/NXL-104, which is in Phase 3 development, and Cubist's CXA-201, which is also in Phase 3 development. We expect that GSK '052 will face competition
from new antibiotics entering the market to address this ongoing need.
Government Regulation
Federal Food, Drug and Cosmetic Act
Prescription drug products are subject to extensive pre- and post-market regulation by the FDA, including
regulations that govern the testing, manufacturing, safety, efficacy, labeling, storage, record keeping, advertising and promotion of such products under the Federal Food, Drug and Cosmetic Act, or
FFDCA, and its implementing regulations. The process of obtaining FDA approval and achieving and maintaining compliance with applicable laws and regulations requires the expenditure of substantial
time and financial resources. Failure to comply with applicable FDA or other requirements may result in refusal to approve pending applications, a clinical hold, warning letters, civil or criminal
penalties, recall or seizure of products, partial or total suspension of production or withdrawal of the product from the market. FDA approval is required before any new drug or dosage form, including
a new use of a previously approved drug, can be marketed in the United States. All applications for FDA approval must contain, among other things, information relating to safety and efficacy,
pharmaceutical formulation, stability, manufacturing, processing, packaging, labeling and quality control.
The FDA's new drug approval process generally involves:
-
-
completion of preclinical laboratory and animal safety testing in compliance with the FDA's Good Laboratory Practice, or
GLP, regulations and the International Conference on Harmonisation, or ICH, guidelines;
-
-
submission to the FDA of an IND for human clinical testing, which must become effective before human clinical trials may
begin in the United States;
-
-
performance of adequate and well-controlled human clinical trials to establish the safety and efficacy of the
proposed drug product for each intended use;
-
-
satisfactory completion of an FDA pre-approval inspection of the facility or facilities at which the product
is manufactured to assess compliance with the FDA's cGMP regulations; and
-
-
submission to and approval by the FDA of an NDA.
The
preclinical and clinical testing and approval process requires substantial time, effort and financial resources, and we cannot guarantee that any approvals for our product candidates
will be granted on a timely basis, if at all. Preclinical tests include laboratory evaluation of product chemistry, formulation and stability, as well as studies to evaluate toxicity in animals. The
results of preclinical tests, together with manufacturing information and analytical data, are submitted as part of an IND application to the FDA. The IND automatically becomes effective
30 days after receipt by the FDA, unless the FDA raises concerns or questions about the submission, including concerns that human research subjects will be exposed to unreasonable health risks.
In such a case, the IND sponsor and the
29
Table of Contents
FDA
must resolve any outstanding concerns before clinical trials can begin. Our submission of an IND may not result in FDA authorization to commence clinical trials. A separate submission to an
existing IND must also be made for each successive clinical trial conducted during product development. Further, an independent institutional review board, or IRB, covering each medical center
proposing to conduct clinical trials must review and approve the plan for any clinical trial before it commences at that center and it must monitor the study until completed. The FDA, the IRB or the
Sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. As a separate amendment to an
IND, a sponsor may submit a request for a Special Protocol Assessment, or SPA, from the FDA. Under the SPA procedure, a sponsor may seek the FDA's agreement on the design and size of a clinical trial
intended to form the primary basis of an effectiveness and safety claim. If the FDA agrees in writing, the study design may not be changed after the trial begins, except in limited circumstances, such
as when a substantial scientific issue essential to determining the safety and effectiveness of a product candidate is identified. If the outcome of the trial is successful, the sponsor will
ordinarily be able to rely on it as the primary basis for approval with respect to effectiveness and safety. Clinical testing also must satisfy extensive Good Clinical Practice, or GCP, regulations,
which include requirements that all research subjects provide informed consent and that all clinical studies be conducted under the supervision of one or more qualified investigators.
For
purposes of an NDA submission and approval, human clinical trials are typically conducted in the following sequential phases, which may overlap:
-
-
Phase 1:
Trials are initially conducted in a
limited population to test the product candidate for safety, dose tolerance, absorption, metabolism, distribution and excretion, generally in healthy humans.
-
-
Phase 2:
Trials are generally conducted in a
limited patient population to identify possible adverse effects and safety risks, to determine the initial efficacy of the product for specific targeted indications and to determine dose tolerance and
optimal dosage. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more extensive Phase 3 clinical trials. In some
cases, a sponsor may decide to run what is referred to as a "Phase 2b" evaluation, which is a second, confirmatory Phase 2 clinical trial that could, if positive and accepted by the FDA,
serve as a pivotal trial in the approval of a product candidate.
-
-
Phase 3:
These are commonly referred to as pivotal
studies. When Phase 2 evaluations demonstrate that a dose range of the product is effective and has an acceptable safety profile, Phase 3 clinical trials are undertaken in large patient
populations to further evaluate dosage, to provide substantial evidence of clinical efficacy and to further test for safety in an expanded and diverse patient population at multiple,
geographically-dispersed clinical trial sites. Generally, replicate evidence of safety and effectiveness needs to be demonstrated in two adequate and well-controlled Phase 3
clinical trials of a product candidate for a specific indication. These studies are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for product
labeling.
-
-
Phase 4:
In some cases, the FDA may condition
approval of an NDA for a product candidate on the sponsor's agreement to conduct additional clinical trials to further assess the drug's safety and/or efficacy after NDA approval. Such
post-approval trials are typically referred to as Phase 4 clinical trials.
Progress
reports detailing the results of the clinical studies must be submitted at least annually to the FDA and safety reports must be submitted to the FDA and the investigators for
serious and unexpected adverse events. Concurrent with clinical studies, sponsors usually complete additional animal safety studies and must also develop additional information about the chemistry and
physical
30
Table of Contents
characteristics
of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of
consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final
product. Moreover, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over
its shelf life.
The
results of product development, preclinical studies and clinical trials, along with the aforementioned manufacturing information, are submitted to the FDA as part of an NDA. NDA's
must also contain extensive manufacturing information. Under the Prescription Drug User Fee Act, or PDUFA, the FDA agrees to specific goals for NDA review time through a two-tiered
classification system, Standard Review and Priority Review. Standard Review is applied to a drug that offers at most, only minor improvement over existing marketed therapies. Standard Review NDAs have
a goal of being completed within a ten-month timeframe, although a review can take a significantly longer amount of time. A Priority Review designation is given to drugs that offer major
advances in treatment, or provide a treatment where no adequate therapy exists. A Priority Review means that the time it takes the FDA to review an NDA is reduced such that the goal for completing a
Priority Review initial review cycle is six months. It is likely that our product candidates will be granted Standard Reviews. The review process is often significantly extended by FDA requests for
additional information or clarification. The FDA may refer the application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved. The FDA
is not bound by the recommendation of an advisory committee, but it generally follows such recommendations.
The
FDA may deny approval of an NDA if the applicable regulatory criteria are not satisfied, or it may require additional clinical data or additional pivotal Phase 3 clinical
trials. Even if such data are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data from clinical trials are not always conclusive and the FDA may
interpret data differently than we do. Once issued, product approval may be withdrawn by the FDA if ongoing regulatory requirements are not met or if safety problems occur after the product reaches
the market. In addition, the FDA may require testing, including Phase 4 clinical trials, Risk Evaluation and Mitigation Strategies (REMS) and surveillance programs to monitor the effect of
approved products that have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs. Drugs
may be marketed only for the approved indications and in accordance with the provisions of the approved label. Further, if there are any modifications to the drug, including changes in indications,
labeling or manufacturing processes or facilities, approval of a new or supplemental NDA may be required, which may involve conducting additional preclinical studies and clinical trials.
Under the Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman Amendments, a portion of a
product's patent term that was lost during clinical development and application review by the FDA may be restored. The Hatch-Waxman Amendments also provide for a statutory protection, known as
nonpatent market exclusivity, against the FDA's acceptance or approval of certain competitor applications.
Patent
term restoration can compensate for time lost during product development and the regulatory review process by returning up to five years of patent life for a patent that covers a
new product or its use. This period is generally one-half the time between the effective date of an IND (falling after issuance of the patent) and the submission date of an NDA, plus the
time between the submission date of an NDA and the approval of that application. Patent term restorations, however, cannot extend the remaining term of a patent beyond a total of 14 years. The
application for patent
31
Table of Contents
term
extension is subject to approval by the United States Patent and Trademark Office in conjunction with the FDA. It takes at least six months to obtain approval of the application for patent term
extension. Up to five years of interim one year extensions are available if a product is still undergoing development or FDA review at the time of its expiration.
The
Hatch-Waxman Amendments also provide for a period of statutory protection for new drugs that receive NDA approval from the FDA. If a new drug receives NDA approval as a new chemical
entity, meaning that the FDA has not previously approved any other new drug containing the same active moiety, then the Hatch-Waxman Amendments prohibit submission of an Abbreviated New Drug
Application, or ANDA, or a 505(b)(2) NDA (each as described below) by another company for a generic version of such drug, or modification to the previously approved version, with some exceptions, for
a period of five years from the date of approval of the NDA. The statutory protection provided pursuant to the Hatch-Waxman Amendments will not prevent the filing or approval of a full NDA. In order
to gain approval of a full NDA, however, a competitor would be required to conduct its own preclinical investigations and clinical trials. If NDA approval is received for a new drug containing an
active ingredient that was previously approved by the FDA but the NDA is for a drug that includes an innovation over the previously approved drug and if such NDA approval was dependent upon the
submission to the FDA of new clinical investigations, other than bioavailability studies, then the Hatch-Waxman Amendments prohibit the FDA from making effective the approval of an ANDA or a 505(b)(2)
NDA for a generic version of such drug or modification of the previously approved version for a period of three years from the date of the NDA approval. This three year exclusivity, however, only
covers the innovation associated with the NDA to which it attaches. Thus, the three year
exclusivity does not prohibit the FDA, with limited exceptions, from approving ANDAs or 505(b)(2) NDAs for drugs containing the same active ingredient but without the new innovation.
While
the Hatch-Waxman Amendments provide certain patent term restoration and exclusivity protections to innovator drug manufacturers, it also permits the FDA to approve ANDAs for
generic versions of their drugs. The ANDA process permits competitor companies to obtain marketing approval for a drug with the same active ingredient for the same uses but does not require the
conduct and submission of clinical trials demonstrating safety and effectiveness for that product. Instead of safety and effectiveness data, an ANDA applicant needs only to submit data demonstrating
that its product is bioequivalent to the innovator product as well as relevant chemistry, manufacturing and product data. The Hatch-Waxman Amendments also instituted a third type of drug application
that requires the same information as an NDA including full reports of clinical and preclinical studies except that some of the information from the reports required for marketing approval comes from
studies that the applicant does not own or for which the applicant does not have a legal right of reference. This type of application, a "505(b)(2) NDA," permits a manufacturer to obtain marketing
approval for a drug without needing to conduct or obtain a right of reference for all of the required studies.
Finally,
the Hatch-Waxman Amendments require, in some circumstances, an ANDA or a 505(b)(2) NDA applicant to notify the patent owner and the holder of the approved NDA of the factual and
legal basis of the applicant's opinion that the patent listed by the holder of the approved NDA in FDA's
Approved Drug Products with Therapeutic Equivalence
Evaluations
manual is not valid or will not be infringed (the patent certification process). Upon receipt of this notice, the patent owner and the NDA holder have
45 days to bring a patent infringement suit in federal district court and obtain a 30-month stay against the company seeking to reference the NDA. The NDA or patent holder could
still file a patent suit after the 45 days, but if they did, they would not have the benefit of a 30-month stay. Alternatively, after this 45-day period, the
applicant may file a declaratory judgment action, seeking a determination that the patent is invalid or will not be infringed. The discovery, trial and appeals process in such suits can take
several years. If such a suit is timely commenced, the Hatch-Waxman Amendments provide a 30-month stay on the approval of the competitor's ANDA or 505(b)(2) NDA. If the litigation is
resolved in favor of the competitor or the challenged patent expires
32
Table of Contents
during
a 30-month stay period, unless otherwise extended by court order, the stay is lifted and the FDA may approve the application. The patent owner and the NDA holder have the
opportunity to trigger only a single 30-month stay per ANDA or 505(b)(2) NDA. Once the ANDA or 505(b)(2) NDA applicant has notified the patent owner and the NDA holder of the infringement,
the applicant cannot be subjected to another 30-month stay, even if the applicant becomes aware of additional patents that may be infringed by its product.
In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and
commercial sales and distribution of our future products. Whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign
countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country, and the time may be longer or shorter than that
required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.
Under
European Union regulatory systems, marketing authorizations may be submitted either under a centralized or a mutual recognition procedure. The centralized procedure provides for
the grant of a single marketing authorization that is valid for all European Union member states. The mutual recognition procedure provides for mutual recognition of national approval decisions. Under
this procedure, the holder of a national marketing authorization may submit an application to the remaining member states. Within 90 days of receiving the applications and assessment report,
each member state must decide whether to recognize approval.
Although none of our product candidates has been commercialized for any indication, if they are approved for marketing, commercial
success of our product candidates will depend, in part, upon the availability of coverage and reimbursement from third-party payors at the federal, state and private levels. Government payor programs,
including Medicare and Medicaid, private health care insurance companies and managed-care plans have attempted to control costs by limiting coverage and the amount of reimbursement for
particular drug treatments. The U.S. Congress and state legislatures from time to time propose and adopt initiatives aimed at cost-containment. Ongoing federal and state government
initiatives directed at lowering the total cost of health care will likely continue to focus on health care reform, the cost of prescription pharmaceuticals and on the reform of the Medicare and
Medicaid payment systems. Examples of how limits on drug coverage and reimbursement in the United States may cause reduced payments for drugs in the future
include:
-
-
changing Medicare reimbursement methodologies;
-
-
fluctuating decisions on which drugs to include in formularies;
-
-
revising drug rebate calculations under the Medicaid program; and
-
-
reforming drug importation laws.
Indeed,
the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively, the Healthcare Reform Act, which was
signed into law in March of 2010, substantially changes the way health care is financed by both governmental
33
Table of Contents
and
private insurers, and significantly impacts pharmaceutical manufacturers. The Healthcare Reform Act includes, among other things, the following
measures:
-
-
Annual, non-deductible fees on any entity that manufactures or imports certain prescription drugs;
-
-
Increases in Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program for both branded and generic
drugs;
-
-
A new Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical
effectiveness research;
-
-
New requirements for manufacturers to discount drug prices to eligible patients by 50 percent at the pharmacy level
and for mail order services in order for their outpatient drugs to be covered under Medicare Part D; and
-
-
An increase in the number of entities eligible for discounts under the Public Health Service pharmaceutical pricing
program.
Additionally,
some third-party payors also require pre-approval of coverage for new or innovative drug therapies before they will reimburse health care providers who use such
therapies. While we cannot predict whether any proposed cost-containment measures will be adopted or otherwise implemented in the future, the announcement or adoption of these proposals
could have a material adverse effect on our ability to obtain adequate prices for our product candidates and operate profitably.
We rely, and expect to continue to rely, on third parties for the production of clinical and eventually, commercial, quantities of our
products. We and our third-party manufacturers must comply with applicable FDA regulations relating to FDA's cGMP regulations. The cGMP regulations include requirements relating to organization of
personnel, buildings and facilities, equipment, control of components and drug product containers and closures, production and process controls, packaging and labeling controls, holding and
distribution, laboratory controls, records and reports and returned or salvaged products. The manufacturing facilities for our products must meet cGMP requirements to the satisfaction of the FDA
pursuant to a pre-approval inspection before we can use them to manufacture our products. We and our third-party manufacturers are also subject to periodic inspections of facilities by the
FDA and other authorities, including procedures and operations used in the testing and manufacture of our products to assess our compliance with applicable regulations. Failure to comply with
statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including warning letters, the seizure or recall of products, injunctions, consent decrees placing
significant restrictions on or suspending manufacturing operations and civil and criminal penalties. Adverse experiences with the product must be reported to the FDA and could result in the imposition
of market restriction through labeling changes or in product removal. Product approvals may be withdrawn if compliance with regulatory requirements is not maintained or if problems concerning safety
or efficacy of the product occur following approval.
With respect to post-market product advertising and promotion, the FDA imposes a number of complex regulations on entities
that advertise and promote pharmaceuticals, which include, among others, standards for direct-to-consumer advertising, off-label promotion, industry-sponsored
scientific and educational activities and promotional activities involving the internet. The FDA has very broad enforcement authority under the FFDCA, and failure to abide by these regulations can
result in penalties, including the issuance of a warning letter directing entities to correct deviations from FDA
34
Table of Contents
standards,
a requirement that future advertising and promotional materials be pre-cleared by the FDA and state and federal civil and criminal investigations and prosecutions.
We
are also subject to various laws and regulations regarding laboratory practices, the experimental use of animals and the use and disposal of hazardous or potentially hazardous
substances in connection with our research. In each of these areas, as above, the FDA has broad regulatory and enforcement powers, including the ability to levy fines and civil penalties, suspend or
delay issuance of approvals, seize or recall products and withdraw approvals, any one or more of which could have a material adverse effect on us.
Legal Proceedings
We are not currently a party to any material legal proceedings.
Employees
As of December 31, 2011, we had 80 full-time employees, 31 of whom held Ph.D. or M.D. degrees and 68 of whom were
engaged in full-time research and development activities. We plan to continue to expand our product development programs. To support this growth and to support public company requirements,
we will need to expand our managerial, development, finance and other functions. None of our employees are represented by a labor union and we consider our employee relations to be good.
Facilities
Our corporate headquarters are located in Palo Alto, California, where we lease a 36,960 square-foot building with
laboratory and office space. The lease will terminate in March 2018.
We
also lease approximately 15,300 square feet of laboratory and office space in another building in Palo Alto, California under a lease agreement that terminates in December 2013. In
addition, we have two (2) one-year options to extend the lease through each of 2014 and 2015. We may terminate the lease by providing four months' written notice.

ITEM 1A. RISK FACTORS
Investing in our common stock involves a high degree of risk. You should carefully consider the following risk
factors, as well as the other information in this Annual Report on Form 10-K, before deciding whether to invest in shares of our common stock. The occurrence of any of the following
adverse developments described in the following risk factors could harm our business, financial condition, results of operations or prospects. In that case, the trading price of our common stock could
decline, and you may lose all or part of your investment.
Risks Relating to Our Financial Position and Need for Additional Capital
We have never been profitable. Currently, we have no products approved for commercial sale, and to date we have not generated any revenue from product sales. As a result,
our ability to curtail our losses and reach profitability is unproven, and we may never achieve or sustain profitability.
We are not profitable and do not expect to be profitable in the foreseeable future. We have incurred net losses in each year since our
inception, including net losses of approximately $47.9 million, $10.1 million and $24.8 million for 2011, 2010 and 2009, respectively, and as of December 31, 2011, we had
an accumulated deficit of approximately $159.1 million We have devoted most of our financial resources to research and development, including our preclinical development activities and clinical
trials. We have not completed development of any product candidate and we have therefore not generated any revenues from product sales. We expect to incur increased expenses as we continue
Phase 3 clinical trials of tavaborole, advance our other product candidates and expand our research and development programs. We also expect an increase in our expenses associated with
preparing for commercialization of our product candidates and adding infrastructure to support operations as a public company. As a result of the foregoing, we expect to continue to experience net
losses and negative cash flows for the foreseeable future. These losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders' equity and working capital.
Because
of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or
when, or if, we will be able to achieve or maintain profitability. In addition, our expenses could increase more than currently anticipated if we are required by the United States Food and Drug
Administration, or FDA, to perform studies in addition to those that we currently expect. To date, we have financed our operations primarily through the sale of equity securities, debt arrangements,
government contracts and grants and the payments under our agreements with GlaxoSmithKline LLC, or GSK, Schering Corporation, or Schering, Eli Lilly and Company, or Lilly, and Medicis
Pharmaceutical Corporation, or Medicis. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenues. Revenues from our
collaboration with GSK are uncertain because GSK may not continue to develop GSK2251052, or GSK '052 (formerly known as AN3365), milestones under our agreements with GSK may not be achieved, GSK may
not exercise its option to license additional product candidates that may be identified pursuant to our collaboration with them, these product candidates may not receive regulatory approval or, if
they are approved, such product candidates may not be accepted in the market. In addition, we may not be able to enter into other collaborations that will generate significant cash. If we are unable
to develop and commercialize one or more of our product candidates, or if revenues from any product candidate that receives marketing approval are insufficient, we will not achieve profitability. Even
if we do achieve profitability, we may not be able to sustain or increase profitability.
36
Table of Contents
We have a limited operating history and we expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it
difficult to predict our future performance.
Our operations to date have been primarily limited to developing our technology and undertaking preclinical studies and clinical trials
of our product candidates and we are reliant on collaborators for certain of our other products. We have not yet obtained regulatory approvals for any of our product candidates. Consequently, any
predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history and/or approved products on the market. Our financial condition
and operating results have varied significantly in the past and will continue to fluctuate from quarter-to-quarter or year-to-year due to a variety of
factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include the following risk factors, as well as other factors described
elsewhere in this Annual Report on Form 10-K:
-
-
our ability to obtain additional funding to develop our product candidates;
-
-
the need to obtain and maintain regulatory approval for tavaborole, AN2728, GSK '052, AN8194 or any of our other product
candidates;
-
-
delays in the commencement, enrollment and the timing of clinical testing;
-
-
the success of our clinical trials through all phases of clinical development, including our current Phase 3
clinical trials of tavaborole and future Phase 2 and Phase 3 trials of AN2728;
-
-
any delays in regulatory review and approval of product candidates in clinical development;
-
-
potential side effects of our product candidates that could delay or prevent commercialization or cause an approved drug
to be taken off the market;
-
-
our ability to develop systemic product candidates;
-
-
market acceptance of our product candidates;
-
-
our ability to establish an effective sales and marketing infrastructure;
-
-
competition from existing products or new products that may emerge;
-
-
the ability of patients or healthcare providers to obtain coverage of or sufficient reimbursement for our products;
-
-
our ability to receive approval and commercialize our product candidates outside of the United States;
-
-
our dependency on third-party manufacturers to supply or manufacture our products;
-
-
our ability to establish or maintain collaborations, licensing or other arrangements;
-
-
our ability and third parties' abilities to protect intellectual property rights;
-
-
costs related to and outcomes of potential intellectual property litigation;
-
-
our ability to adequately support future growth;
-
-
our ability to attract and retain key personnel to manage our business effectively;
-
-
our ability to build our finance infrastructure and improve our accounting systems and controls;
-
-
potential product liability claims;
-
-
potential liabilities associated with hazardous materials; and
-
-
our ability to maintain adequate insurance policies.

Due
to the various factors mentioned above, and others, the results of any quarterly or annual periods should not be relied upon as indications of future operating performance.
If we are unable to raise capital when needed, we would be forced to delay, reduce or eliminate our product development programs.
Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. We expect our research
and development expenses to increase in connection with our ongoing activities, particularly our Phase 3 clinical trials of tavaborole and future Phase 2 trials of AN2728. If the FDA
requires that we perform additional studies beyond those that we currently expect, our expenses could increase beyond what we currently anticipate and the timing of any potential product approval may
be delayed. We raised $21.5 million in February 2012 through a public offering of our common stock. We currently have no commitments or arrangements for any additional financing to fund our
research and development programs other than through our loan facility, from which we drew down an additional $8.0 million in December 2011; research funding under our collaboration with Lilly;
reimbursements from our various collaborations with leading not-for-profit organizations related to our neglected diseases initiatives; and contingent milestone or royalty
payments from GSK, Lilly or Medicis, which we may not receive. We believe our existing cash, cash equivalents and short-term investments and interest thereon will be sufficient to fund our
projected operating requirements for at least the next 12 months. However, we may need to raise substantial additional capital in the future to complete the development and commercialization of
our product candidates.
Until
we can generate a sufficient amount of revenue from our products, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings or
corporate collaborations and licensing arrangements. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may
be required to delay, reduce the scope of or eliminate one or more of our research or development programs or our commercialization efforts. To the extent that we raise additional funds by issuing
equity securities, our stockholders may experience additional dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through
collaborations and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or grant licenses on terms that may not be favorable to us. We
may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.
Our
forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties,
and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this "Risk Factors" section. We have based this estimate on assumptions that may prove to
be wrong, and we could utilize our available capital resources sooner than we currently expect.
Our
future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:
-
-
the initiation, progress, timing, costs and results of preclinical studies and clinical trials for our product candidates
and potential product candidates, including conduct of Phase 3 clinical trials for tavaborole and initiation of future Phase 2 and Phase 3 clinical trials for AN2728;
-
-
the success of our collaborations with GSK, Lilly and Medicis and the attainment of milestones and royalty payments, if
any, under those agreements;
-
-
the number and characteristics of product candidates that we pursue;
-
-
the terms and timing of any future collaboration, licensing or other arrangements that we may establish;
38

-
-
the outcome, timing and cost of regulatory approvals;
-
-
the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
-
-
the effect of competing technological and market developments;
-
-
the cost and timing of completion of commercial-scale outsourced manufacturing activities;
-
-
the cost of establishing sales, marketing and distribution capabilities for any product candidates for which we may
receive regulatory approval; and
-
-
the extent to which we acquire or invest in businesses, products or technologies.
Raising funds through lending arrangements may restrict our operations or produce other adverse results.
Our current loan and security agreement with Oxford Finance LLC and Horizon Technology Finance Corporation, which we entered
into in March 2011 and amended in December 2011 in connection with our drawing down an additional $8.0 million, contains a variety of affirmative and negative covenants, including required
financial reporting, limitations on certain dispositions of assets, limitations on the incurrence of additional debt and other requirements. To secure our performance of our obligations under this
loan and security agreement, we granted a security interest in substantially all of our assets, other than intellectual property assets, to the lenders. Our failure to comply with the covenants in the
loan and security agreement, the occurrence of a material impairment in our prospect of repayment or in the perfection or priority of the lender's lien on our assets, as determined by the lenders, or
the occurrence of certain other specified events could result in an event of default that, if not cured or waived, could result in the acceleration of all or a substantial portion of our debt,
potential foreclosure on our assets, and other adverse results.
Risks Relating to the Development, Regulatory Approval and Commercialization of Our Product Candidates
We cannot be certain that tavaborole, AN2728, GSK '052, AN8194 or any of our other product candidates will receive regulatory approval, and without regulatory approval our
product candidates will not be able to be marketed.
We have invested a significant portion of our efforts and financial resources in the development of our most advanced product
candidates, especially tavaborole. Our ability to generate revenue related to product sales, which we do not expect will occur for at least the next several years, if ever, will depend on the
successful development and regulatory approval of our product candidates.
In
August 2010, we filed a Special Protocol Assessment request with the FDA and reached agreement on what we believe are the major parameters associated with the design and conduct of
the current Phase 3 trials for tavaborole. We commenced Phase 3 clinical trials of tavaborole in the fourth quarter of 2010, and completed enrollment in December 2011. We may conduct
lengthy and expensive Phase 3 clinical trials of tavaborole only to learn that this drug candidate is not a safe or effective treatment, in which case these clinical trials may not lead to
regulatory approval for tavaborole. Similarly, our clinical development programs for AN2728, GSK's development programs for GSK '052 and Lilly's development programs for AN8194 may not lead to
regulatory approval from the FDA and similar foreign regulatory agencies. This failure to obtain regulatory approvals would prevent our product candidates from being marketed and would have a material
and adverse effect on our business.
We
currently have no products approved for sale and we cannot guarantee that we will ever have marketable products. The development of a product candidate, including preclinical and
clinical testing, manufacturing, quality systems, labeling, approval, record-keeping, selling, promotion, marketing and distribution of products, is subject to extensive regulation by the FDA in the
United States and
39
Table of Contents
regulatory
authorities in other countries, with regulations differing from country to country. We are not permitted to market our product candidates in the United States until we receive approval of a
new drug application, or NDA, from the FDA. We have not submitted an NDA for any of our product candidates. Obtaining approval of an NDA is a lengthy, expensive and uncertain process. An NDA must
include extensive preclinical and clinical data and supporting information to establish the product candidate's safety and effectiveness for each indication. The approval application must also include
significant information regarding the chemistry, manufacturing and controls for the product. The FDA review process typically takes years to complete and approval is never guaranteed. If a product is
approved, the FDA may limit the indications for which the product may be used, include extensive warnings on the product labeling or require costly ongoing requirements for post-marketing
clinical studies and surveillance or other risk management measures to monitor the safety or efficacy of the product candidate. Markets outside of the United States also have
requirements for approval of drug candidates with which we must comply prior to marketing. Obtaining regulatory approval for marketing of a product candidate in one country does not ensure we will be
able to obtain regulatory approval in other countries but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in other countries.
Also, any regulatory approval of any of our products or product candidates, once obtained, may be withdrawn. If tavaborole, AN2728, GSK '052, AN8194 or any of our other product candidates do not
receive regulatory approval, we may not be able to generate sufficient revenue to become profitable or to continue our operations.
Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval
for our product candidates.
Delays in the commencement, enrollment and completion of clinical trials could increase our product development costs or limit the
regulatory approval of our product candidates. We do not know whether clinical trials of tavaborole, AN2728, GSK '052 or other product candidates will begin on time or, if commenced, will be completed
on schedule or at all. The commencement, enrollment and completion of clinical trials can be delayed for a variety of reasons, including:
-
-
inability to reach agreements on acceptable terms with prospective clinical research organizations, or CROs, and trial
sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
-
-
regulatory objections to commencing a clinical trial;
-
-
inability to identify and maintain a sufficient number of trial sites, many of which may already be engaged in other
clinical trial programs, including some that may be for the same indication as our product candidates;
-
-
withdrawal of clinical trial sites from our clinical trials as a result of changing standards of care or the ineligibility
of a site to participate in our clinical trials;
-
-
inability to obtain institutional review board, or IRB, approval to conduct a clinical trial at prospective sites;
-
-
difficulty recruiting and enrolling patients to participate in clinical trials for a variety of reasons, including meeting
the enrollment criteria for our study and competition from other clinical trial programs for the same indication as our product candidates; and
-
-
inability to retain patients in clinical trials due to the treatment protocol, personal issues, side effects from the
therapy or lack of efficacy, particularly for those patients receiving either a vehicle without the active ingredient or a placebo. For example, our Phase 3 clinical trials of tavaborole, which
completed enrollment in December 2011, have a treatment duration of 48 weeks, and it may be difficult to retain patients for this entire period.
40
Table of Contents
In
addition, a clinical trial may be suspended or terminated by us, our current or any future partners, the FDA or other regulatory authorities due to a number of factors,
including:
-
-
failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;
-
-
failed inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities;
-
-
unforeseen safety or efficacy issues or any determination that a clinical trial presents unacceptable health risks; or
-
-
lack of adequate funding to continue the clinical trial due to unforeseen costs resulting from enrollment delays,
requirements to conduct additional trials and studies, increased expenses associated with the services of our CROs and other third parties or other reasons.
If
we are required to conduct additional clinical trials or other testing of our product candidates beyond those currently contemplated, we may be delayed in obtaining, or may not be
able to obtain, marketing approval for these product candidates.
In
addition, if our current or any future partners assume development of our product candidates, they may suspend or terminate their development and commercialization efforts, including
clinical trials for our product candidates, at any time. For example, with the license of GSK '052, GSK now controls the development and commercialization of GSK '052, and in March 2012 GSK
voluntarily discontinued certain of its current clinical trials of GSK '052 but did not terminate the program, while it reviews and assesses the data from the patients in those clinical trials. While
GSK stated that its review relates to microbiological findings, there can be no assurance that following its review GSK will continue the GSK '052 program, and in any event if GSK determines to
proceed, any clinical trials will have been delayed significantly by the time taken for preparation, review and consideration of the patient data available from the discontinued clinical trials.
Changes
in regulatory requirements and guidance may occur and we or any partners may need to amend clinical trial protocols to reflect these changes with appropriate regulatory
authorities. Amendments may require us or any partners to resubmit clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of a
clinical trial. If we or any of our partners experience delays in the completion of, or if we or our partners terminate, clinical trials, the commercial prospects for our product candidates will be
harmed, and our ability to generate revenue from sales of our products will be prevented or delayed. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion
of clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate.
Clinical failure can occur at any stage of clinical development. Because the results of earlier clinical trials are not necessarily predictive of future results, any product
candidate we, GSK or our potential future partners advance through clinical trials may not have favorable results in later clinical trials or receive regulatory approval.
Clinical failure can occur at any stage of our clinical development. Clinical trials may produce negative or inconclusive results, and
we or our partners may decide, or regulators may require us, to conduct additional clinical or preclinical testing. In addition, data obtained from tests are susceptible to varying interpretations,
and regulators may not interpret our data as favorable as we do, which may delay, limit or prevent regulatory approval. Success in preclinical testing and early
clinical trials does not ensure that later clinical trials will generate the same results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate. Frequently,
product candidates that have shown promising results in early clinical trials have subsequently suffered significant setbacks in later clinical trials. In addition, the design of a clinical trial can
determine whether its results will support
41
Table of Contents
approval
of a product and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. We have limited experience in designing clinical trials and may be
unable to design and execute a clinical trial to support regulatory approval. Further, clinical trials of potential products often reveal that it is not practical or feasible to continue development
efforts. If tavaborole, AN2728, GSK '052, AN5568 or our other product candidates are found to be unsafe or lack efficacy, we or our collaborators will not be able to obtain regulatory approval for
them and our business would be harmed. For example, if the results of our current Phase 3 clinical trials of tavaborole and planned Phase 3 clinical trials of AN2728 do not achieve the
primary efficacy endpoints and demonstrate an acceptable safety level, the prospects for approval of tavaborole and AN2728 would be materially and adversely affected. A number of companies in the
pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in Phase 3 clinical trials, even after seeing promising results in
earlier clinical trials.
In
some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including
changes in trial protocols, differences in size and type of the patient populations, adherence to the dosing regimen, particularly for self-administered topical drugs, and other trial
protocols and the rate of dropout among clinical trial participants. We do not know whether any Phase 2, Phase 3 or other clinical trials we or any partners may conduct will demonstrate
consistent and/or adequate efficacy and safety to obtain regulatory approval to market our product candidates.
We have never conducted a Phase 3 clinical trial or submitted an NDA before, and may be unable to do so for tavaborole, AN2728 and other product candidates we are
developing.
We are conducting the Phase 3 clinical trials of tavaborole and planning to conduct the Phase 3 clinical trials of AN2728
following Phase 2b studies of AN2728 in atopic dermatitis. The conduct of Phase 3 clinical trials and the submission of a successful NDA is a complicated process. We have not conducted a
Phase 3 clinical trial before, have limited experience in preparing, submitting and prosecuting regulatory filings, and have not submitted an NDA before. Consequently, we may be unable to
successfully and efficiently execute and complete these planned clinical trials in a way that leads to NDA submission and approval of tavaborole, AN2728 and other product candidates we are developing.
We may require more time and incur greater costs than our competitors and may not succeed in obtaining regulatory approvals of products that we develop. Failure to commence or
complete, or delays in, our planned clinical trials, would prevent us from or delay us in commercializing tavaborole, AN2728 and other product candidates we are developing.
Our product candidates may have undesirable side effects which may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market
or otherwise limit their sales.
Unforeseen side effects from any of our product candidates could arise either during clinical development or, if approved, after the
approved product has been marketed. For example, a small number of patients who received tavaborole treatment experienced some skin irritation around their toenails during clinical trials of
tavaborole for onychomycosis. In addition, a small number of patients who received AN2728 treatment experienced some skin irritation during clinical trials of AN2728 for psoriasis, and one serious
adverse event was reported in a patient who developed a rash after receiving an injection of penicillin outside the trial for a sore throat and needed to be hospitalized for this non-life
threatening reaction. GSK '052 is being developed for the systemic treatment of infections caused by Gram-negative bacteria and is still in the early stages of clinical development. The
range and potential severity of possible side effects from systemic therapies is greater than for topically administered drugs. The results of future clinical trials may show that our product
candidates cause undesirable or unacceptable side effects, which could interrupt, delay or halt clinical trials, resulting in delay of, or failure to obtain, marketing approval from the FDA and other
regulatory authorities.
42
Table of Contents
If any of our product candidates receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by such
products:
-
-
regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field
alerts to physicians and pharmacies;
-
-
we may be required to change the way the product is administered, conduct additional clinical trials or change the
labeling of the product;
-
-
we may have limitations on how we promote the product;
-
-
sales of the product may decrease significantly;
-
-
regulatory authorities may require us to take our approved product off the market;
-
-
we may be subject to litigation or product liability claims; and
-
-
our reputation may suffer.
Any
of these events could prevent us, GSK, Lilly, Medicis or our potential future partners from achieving or maintaining market acceptance of the affected product or could substantially
increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from the sale of our products.
All of our product candidates require regulatory review and approval prior to commercialization. Any delay in the regulatory review or approval of any of our product
candidates will harm our business.
All of our product candidates require regulatory review and approval prior to commercialization. Any delays in the regulatory review or
approval of our product candidates would delay market launch, increase our cash requirements and result in additional operating losses.
The
process of obtaining FDA and other required regulatory approvals, including foreign approvals, often takes many years and can vary substantially based upon the type, complexity and
novelty of the products involved. Furthermore, this approval process is extremely complex, expensive and uncertain. We, GSK, Lilly, Medicis or our potential future partners may be unable to submit any
NDA in the United States or any marketing approval application or other foreign applications for any of our products. If we or our partners submit any NDA, including any amended NDA or supplemental
NDA, to the FDA seeking marketing approval for any of our product candidates, the FDA must decide whether to either accept or reject the submission for filing. We cannot be certain that any of these
submissions will be accepted for filing and reviewed by the FDA, or that the marketing approval application submissions to any other regulatory authorities will be accepted for filing and review by
those authorities. We cannot be certain that we or our partners will be able to respond to any
regulatory requests during the review period in a timely manner without delaying potential regulatory action. We also cannot be certain that any of our product candidates will receive favorable
recommendations from any FDA advisory committee or foreign regulatory bodies or be approved for marketing by the FDA or foreign regulatory authorities. In addition, delays in approvals or rejections
of marketing applications may be based upon many factors, including regulatory requests for additional analyses, reports, data and studies, regulatory questions regarding data and results, changes in
regulatory policy during the period of product development and the emergence of new information regarding our product candidates or other products.
Data
obtained from preclinical studies and clinical trials are subject to different interpretations, which could delay, limit or prevent regulatory review or approval of any of our
product candidates. In addition, as a routine part of the evaluation of any potential drug, clinical trials are generally conducted to assess the potential for drug-to-drug
interactions that could impact potential product safety. To date, we have not been requested to perform drug-to-drug interaction studies on our topical product
43
Table of Contents
candidates,
but any such request, which would be more typical with a systemic product candidate, may delay any potential product approval and may increase the expenses associated with clinical
programs. Furthermore, regulatory attitudes towards the data and results required to demonstrate safety and efficacy can change over time and can be affected by many factors, such as the emergence of
new information, including on other products, policy changes and agency funding, staffing and leadership. We do not know whether future changes to the regulatory environment will be favorable or
unfavorable to our business prospects.
In
addition, the environment in which our regulatory submissions may be reviewed changes over time. For example, average review times at the FDA for NDAs have fluctuated over the last
ten years, and we cannot predict the review time for any of our submissions with any regulatory authorities. Review times can be affected by a variety of factors, including budget and funding levels
and statutory, regulatory and policy changes. Moreover, in light of widely publicized events concerning the safety risk of certain drug products, regulatory authorities, members of Congress, the
Government Accounting Office, medical professionals and the general public have raised concerns about potential drug safety issues. These events have resulted in the withdrawal of drug products,
revisions to drug labeling that further limit use of the drug products and establishment of risk evaluation and mitigation strategies, or REMS, that may, for instance, restrict distribution of drug
products. The increased attention to drug safety issues may result in a more cautious approach by the FDA to clinical trials. Data from clinical trials may receive greater scrutiny with respect to
safety, which may make the FDA or other regulatory authorities more likely to terminate clinical trials before completion, or require longer or additional clinical trials that may result in
substantial additional expense and a delay or failure in obtaining approval or may result in approval for a more limited indication than originally sought.
Our use of boron chemistry to develop pharmaceutical product candidates is novel and may not prove successful in producing approved products. Undesirable side effects of any
of our product candidates, or of boron-based drugs developed by others, may extend the time period required to obtain regulatory approval or harm market acceptance of our product candidates, if
approved.
All of our product development activities are centered around compounds containing boron. The use of boron chemistry to develop new
drugs is largely unproven. If boron-based compounds developed by us or others have significant adverse side effects, regulatory authorities could require additional studies of our boron-based
compounds, which could delay the timing of and increase the cost for regulatory approvals of our product candidates. Additionally, adverse side effects for other boron-based compounds could affect the
willingness of third-party payors and medical providers to provide reimbursement for or use our boron-based drugs and could impact market acceptance of our products.
Additionally,
there can be no assurance that boron-based products will be free of significant adverse side effects. During clinical trials, a small number of our patients who received
tavaborole experienced some skin irritation around their toenails and a few patients who received AN2728 experienced some skin irritation around their psoriasis plaques. In addition, during the course
of a clinical trial of AN2728 for psoriasis, one serious adverse event was reported in a patient who developed a rash after receiving an injection of penicillin outside of the trial for a sore throat
and needed to be hospitalized for this non-life-threatening reaction. If boron-based drug treatments result in significant adverse side effects, they may not be useful as
therapeutic agents. If we are unable to develop products that are safe and effective using our boron chemistry platform, our business will be materially and adversely affected.
If any of our product candidates for which we receive regulatory approval do not achieve broad market acceptance, the revenues that are generated from their sales will be
limited.
The commercial success of tavaborole, AN2728, GSK '052, AN8194 or our other product candidates will depend upon the acceptance of these
products among physicians, patients and the
44
Table of Contents
medical
community. The degree of market acceptance of our product candidates will depend on a number of factors, including:
-
-
limitations or warnings contained in a product's FDA-approved labeling;
-
-
changes in the standard of care for the targeted indications for any of our product candidates;
-
-
limitations in the approved indications for our product candidates;
-
-
lower demonstrated clinical safety and efficacy compared to other products;
-
-
lack of significant adverse side effects;
-
-
ineffective sales, marketing and distribution support;
-
-
lack of availability of reimbursement from managed care plans and other third-party payors;
-
-
timing of market introduction and perceived effectiveness of competitive products;
-
-
lack of cost-effectiveness;
-
-
availability of alternative therapies at similar or lower cost, including generics and
over-the-counter products;
-
-
adverse publicity about our product candidates or favorable publicity about competitive products;
-
-
convenience and ease of administration of our products; and
-
-
potential product liability claims.
If
our product candidates for human use are approved, but do not achieve an adequate level of acceptance by physicians, health care payors and patients, sufficient revenue may not be
generated from these products, and we may not become or remain profitable. In addition, efforts to educate the medical community and third-party payors on the benefits of our product candidates may
require significant resources and may never be successful.
We have never marketed a drug before, and if we are unable to establish an effective sales force and marketing infrastructure, or enter into acceptable third-party sales and
marketing or licensing arrangements, we may not be able to commercialize our product candidates successfully.
We may develop a sales and marketing infrastructure to market and sell our products in certain U.S. specialty markets. We currently do
not have any sales, distribution and marketing capabilities, the development of which will require substantial resources and will be time consuming. We are currently evaluating the establishment of
these capabilities, and these costs are expected to be incurred in advance of any approval of our product candidates. In addition, we may not be able to hire a sales force in the United States that is
sufficient in size or has adequate expertise in the medical markets that we intend to target. If we are unable to establish our sales force and marketing capability, our operating results may be
adversely affected. In addition, we plan to enter into sales and marketing or licensing arrangements with third parties for non-specialty markets in the United States and for international
sales of any approved products. If we are unable to enter into any such arrangements on acceptable terms, or at all, we may be unable to market and sell our products in these markets.
We expect that our existing and future product candidates will face competition and most of our competitors have significantly greater resources than we do.
The pharmaceutical industry is highly competitive, with a number of established, large pharmaceutical companies, as well as many
smaller companies. Most of these companies have significant financial resources, marketing capabilities and experience in obtaining regulatory approvals for product candidates. There are many
pharmaceutical companies, biotechnology companies, public
45
Table of Contents
and
private universities, government agencies and research organizations actively engaged in research and development of products that may target the same markets as our product candidates. We expect
any future products we develop to compete on the basis of, among other things, product efficacy, price, lack of significant adverse side effects and convenience and ease of treatment.
Compared
to us, many of our potential competitors have substantially greater:
-
-
resources, including capital, personnel and technology;
-
-
research and development capability;
-
-
clinical trial expertise;
-
-
regulatory expertise;
-
-
intellectual property portfolios;
-
-
expertise in prosecution of intellectual property rights;
-
-
manufacturing and distribution expertise; and
-
-
sales and marketing expertise.
As
a result of these factors, our competitors may obtain regulatory approval of their products more rapidly than we are able to or may obtain patent protection or other intellectual
property rights that limit our ability to develop or commercialize our product candidates. Our competitors may also develop drugs that are more effective, more widely used and less costly than ours
and may also be more successful than us in manufacturing and marketing their products.
The dermatology market is competitive, which may adversely affect our ability to commercialize our dermatological product candidates.
If tavaborole is approved for the treatment of onychomycosis, we anticipate that it would compete with other marketed nail fungal
therapeutics including Lamisil, Sporanox, Penlac and generic versions of those compounds as well as lasers which have received clearance from the FDA for the treatment of onychomycosis. Tavaborole
will also compete against over-the-counter products and possibly various other devices under development for onychomycosis. If approved for the treatment of atopic dermatitis
and/or psoriasis, AN2728 will compete against a number of approved topical treatments, including for atopic dermatitis, other marketed atopic dermatitis therapeutics, which typically include
combinations of antibiotics, antihistamines, topical corticosteroids and topical immunomodulators, such as Elidel (pimecrolimus) and Protopic (tacrolimus) and for psoriasis, Taclonex (a combination of
calcipotriene and the high potency corticosteroid betamethasone dipropionate), Dovonex (calcipotriene), Tazorac (tazarotene) and generic versions, where available. AN2728 would also compete against
systemic treatments for psoriasis, which include oral products such as methotrexate and cyclosporine and injected biologic products such as Enbrel, Remicade, Stelara, Simponi, Amevive, and Humira. A
number of other treatments are used for psoriasis, including light based treatments and non-prescription topical treatments.
There
are also several pharmaceutical product candidates under development that could potentially be used to treat onychomycosis and compete with tavaborole. Product candidates in
late-stage development include a novel topical triazole which completed Phase 3 development in December 2011 and was developed by Dow Pharmaceutical Sciences, or DPS, a wholly-owned
subsidiary of Valeant Pharmaceuticals International, an undisclosed topical product candidate in Phase 3 development by Promius Pharma, LLC, a wholly-owned subsidiary of
Dr. Reddy's Laboratories, and a topical reformulation of terbinafine in Phase 3 development by Celtic Pharma Management L.P. There are also several companies pursuing various
devices for onychomycosis, including laser technology. For example, at least three lasers have received FDA clearance for the treatment of onychomycosis. In addition,
46
Table of Contents
there
are a number of earlier stage therapeutics and devices in various stages of development for the treatment of onychomycosis.
Even
if a generic product or an over-the-counter product is less effective than our product candidates, a less effective generic or
over-the-counter product may be more quickly adopted by health insurers and patients than our competing product candidates based upon cost or convenience. In addition, each of
our product candidates may compete against product candidates currently under development by other companies.
Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance. If there is not sufficient reimbursement for our products, it is
less likely that our products will be widely used.
Successful commercialization of pharmaceutical products usually depends on the availability of adequate coverage and reimbursement from
third-party payors. Patients or healthcare providers who purchase drugs generally rely on third-party payors to reimburse all or part of the costs associated with such products. Adequate coverage and
reimbursement from governmental payors, such as Medicare and Medicaid, and commercial payors, such as HMOs and insurance companies, can be central to new product acceptance.
Current
treatments for onychomycosis are often not reimbursed by third-party payors. We do not know the extent to which tavaborole will be reimbursed if it is approved. Reimbursement
decisions by third-party payors may have an effect on pricing and market acceptance. Our other product candidates,
such as AN2728 and GSK '052, will also be subject to uncertain reimbursement decisions by third-party payors. Our products are less likely to be used if they do not receive adequate reimbursement.
The
market for our product candidates may depend on access to third-party payors' drug formularies, or lists of medications for which third-party payors provide coverage and
reimbursement. Industry competition to be included in such formularies results in downward pricing pressures on pharmaceutical companies. Third-party payors may refuse to include a particular branded
drug in their formularies when a competing generic product is available.
All
third-party payors, whether governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the United States, no
uniform policy of coverage and reimbursement for medicines exists among all these payors. Therefore, coverage of and reimbursement for drugs can differ significantly from payor to payor and can be
difficult and costly to obtain.
Healthcare policy changes, including the Healthcare Reform Act, may have a material adverse effect on us.
Healthcare costs have risen significantly over the past decade. The Patient Protection and Affordable Care Act, as amended by the
Health Care and Education Reconciliation Act of 2010, or collectively, the Healthcare Reform Act, substantially changes the way healthcare is financed by both governmental and private insurers, and
significantly impacts the pharmaceutical industry. The Healthcare Reform Act contains a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement changes
and fraud and abuse, which will impact existing government healthcare programs and will result in the development of new programs, including Medicare payment for performance initiatives and
improvements to the physician quality reporting system and feedback program. We anticipate that if we obtain approval for our products, some of our revenue may be derived from U.S. government
healthcare programs, including Medicare. In addition, the Healthcare Reform Act imposes a non-deductible excise tax on pharmaceutical manufacturers or importers who sell "branded
prescription drugs," which includes innovator drugs and biologics (excluding orphan drugs or generics) to U.S. government programs. We expect that the Healthcare Reform Act and other healthcare reform
measures that may be adopted in the future could have a
47
Table of Contents
material
adverse effect on our industry generally and our ability to successfully commercialize our products or could limit or eliminate our spending on development projects.
In
addition to the Healthcare Reform Act, there will continue to be proposals by legislators at both the federal and state levels, regulators and third-party payors to keep these costs
down while expanding individual healthcare benefits. Certain of these changes could impose limitations on the prices we will be able to charge for any products that are approved or the amounts of
reimbursement available for these products from governmental agencies or third-party payors or may increase the tax requirements for life sciences companies such as ours. While it is too early to
predict what effect the recently enacted Healthcare Reform Act or any future legislation or regulation will have on us, such laws could have a material adverse effect on our business, financial
position and results of operations.
We expect that a substantial portion of the market for our products will be outside the United States. Our product candidates may never receive approval or be commercialized
outside of the United States.
We plan to enter into sales and marketing arrangements with third parties for international sales of any approved products. To market
and commercialize any product candidates outside of the United States, we, GSK or any other third parties that are marketing or selling our products must establish and comply with numerous and varying
regulatory requirements of other countries regarding safety and efficacy. Approval procedures vary among countries and can involve additional product testing and additional administrative review
periods. The regulatory approval process in other countries may include all of the risks detailed above regarding failure to obtain FDA approval in the United States as well as other risks. Regulatory
approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in
others. Failure to obtain regulatory approval in other countries or any delay or setback in obtaining such approval could have the same adverse effects detailed above regarding FDA approval in the
United States. As described above, such effects include the risks that our product candidates may not be approved for all indications requested, or at all, which could limit the uses of our product
candidates and have an adverse effect on product sales and potential royalties, and that such approval may be subject to limitations on the indicated uses for which the product may be marketed or
require costly post-marketing follow-up studies.
Even if our product candidates receive regulatory approval, we may still face future development and regulatory difficulties.
Even if regulatory approval is obtained for any of our product candidates, regulatory authorities may still impose significant
restrictions on a product's indicated uses or marketing or impose ongoing requirements for potentially costly post-approval studies. Given the number of high profile adverse safety events
with certain drug products, regulatory authorities may require, as a condition of approval, costly risk evaluation and mitigation strategies, which may include safety surveillance, restricted
distribution and use, patient education, enhanced labeling, expedited reporting of certain adverse events, pre-approval of promotional materials and restrictions on
direct-to-consumer advertising. For example, any labeling approved for any of our product candidates may include a restriction on the term of its use, or it may
not include one or more of our intended indications. Furthermore, any new legislation addressing drug safety issues could result in delays or increased costs during the period of product development,
clinical trials and regulatory review and approval, as well as increased costs to assure compliance with any new post-approval regulatory requirements. Any of these restrictions or
requirements could force us or our partners to conduct costly studies.
Our
product candidates will also be subject to ongoing regulatory requirements for the labeling, packaging, storage, advertising, promotion, record-keeping and submission of safety and
other post-market information on the drug. In addition, approved products, manufacturers and manufacturers' facilities are required to comply with extensive FDA requirements, including
ensuring
48
Table of Contents
that
quality control and manufacturing procedures conform to current Good Manufacturing Practices, or cGMP. As such, we and our contract manufacturers are subject to continual review and periodic
inspections to assess compliance with cGMP. Accordingly, we and others with whom we work must continue to expend time, money, and effort in all areas of regulatory compliance, including manufacturing,
production, and quality control. We will also be required to report certain adverse reactions and production problems, if any, to the FDA, and to comply with certain requirements concerning
advertising and promotion for our products. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and must be consistent with the
information in the product's approved label. As such, we may not promote our products for indications or uses for which they do not have approval.
If
a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the
product is manufactured, or disagrees with the promotion, marketing, or labeling of a product, a regulatory agency may impose restrictions on that product or us, including requiring withdrawal of the
product from the market. If our product candidates fail to comply with applicable regulatory requirements, a regulatory agency may:
-
-
issue warning letters;
-
-
mandate modifications to promotional materials or require us to provide corrective information to healthcare
practitioners;
-
-
require us or our partners to enter into a consent decree, which can include imposition of various fines, reimbursements
for inspection costs, required due dates for specific actions and penalties for noncompliance;
-
-
impose other civil or criminal penalties;
-
-
suspend regulatory approval;
-
-
suspend any ongoing clinical trials;
-
-
refuse to approve pending applications or supplements to approved applications filed by us, GSK or our potential future
partners;
-
-
impose restrictions on operations, including costly new manufacturing requirements; or
-
-
seize or detain products or require a product recall.
Guidelines and recommendations published by various organizations may affect the use of our products.
Government agencies may issue regulations and guidelines directly applicable to us, GSK or our potential future partners and our
product candidates. In addition, professional societies, practice management groups, private health/science foundations, and organizations involved in various diseases from time to time publish
guidelines or recommendations to the health care and patient communities. These various sorts of recommendations may relate to such matters as product usage, dosage, route of administration and use of
related or competing therapies.
Changes to these recommendations or other guidelines advocating alternative therapies could result in decreased use of our products, which may adversely affect our results of operations.

Risks Related to Our Dependence on Third Parties
We are dependent on our existing third party collaborations to fund additional development opportunities and expect to continue to expend resources in our current
collaborations with GSK, Lilly and Medicis. These research collaborations may fail to successfully identify product candidates, or our collaboration partners may elect not to license, develop or
commercialize any of the resulting compounds, including, in the case of GSK, compounds in development by us with respect to which GSK has option rights as well as a compound (GSK '052) for which GSK
has sole development and commercialization rights. In the event our collaborator does not elect to exercise its option or elects not to develop or commercialize our collaboration candidate products,
our operating results and financial condition could be materially and adversely affected.
We currently have three significant ongoing collaboration agreements: our most advanced arrangement, an October 2007 research and
development collaboration, option and license agreement with GSK for the discovery, development, manufacture and worldwide
commercialization of novel systemic anti-infectives for viral and bacterial diseases utilizing our boron-based chemistry; an August 2010 collaborative research, license and
commercialization agreement with Lilly for the discovery, development, and worldwide commercialization of animal health products for specific applications; and a February 2011 research and development
option and license agreement with Medicis for the discovery, development, and worldwide commercialization of novel boron-based compounds directed against a specific target for the treatment of acne.
During
the research terms of the collaborations, we (and in some cases also our partner) are committed to use our diligent efforts to discover and develop compounds and to provide
specified resources, on a project-by-project basis. We are either reimbursed our research costs, or each party is responsible for its own research costs, but in all cases we
expect to continue to expend resources on the collaborations. If we fail to successfully identify product candidates or, in some cases, demonstrate proof-of-concept for those
product candidates we identify, our operating results and financial condition could be materially and adversely affected. In addition, we may mutually agree with our collaboration partner not to
pursue all of the research activities contemplated under the applicable agreement. Our collaboration partners have the option, but are not required, to exclusively license or select for further
development certain product candidates under the agreement once the product candidate meets specified criteria, subject to continuing obligations to make milestone payments and royalty payments on
commercial sales, if any, of such licensed compounds. Typically, the collaboration partner is obligated to make payments to us upon the achievement of certain initial discovery and developmental
milestones, but further, more significant milestone payments are payable only on compounds that the partner chooses to license or develop, such as GSK '052 in the case of GSK. If we devote significant
resources to a research project and our collaboration partner elects not to exercise its option with respect to or develop any resulting product candidates, our financial condition could be materially
and adversely affected. In certain cases, if our partner does not exercise a given option or terminates development, we may request a license to develop and commercialize products containing the
relevant compounds. If we make such request, we will be obligated to pay certain milestones and royalties if we elect to develop and commercialize such products.
If
our collaboration partner elects to license or develop a compound, like GSK has with GSK '052 and Lilly has with AN8194, the partner assumes sole responsibility for further
development, regulatory approval and commercialization of such compound. Thus, with respect to compounds that our partner chooses to develop, the timing of development and future payments to us,
including milestone and royalty payments, will depend on the extent to which such licensed compounds advance through development, regulatory approval and commercialization by our partner.
Additionally, our partner can choose to terminate the agreement with a specified notice period or its license to any compounds at any time with no further obligation to develop and commercialize such
compounds. In such event, we would not be eligible to receive further payments for the affected compounds. We would retain rights to develop and market any such product candidates. However, we would
be required to fund further
50
Table of Contents
development
and commercialization ourselves or with other partners if we continue to pursue these product candidates, and in some cases would owe our previous partner royalties to continue to develop
and commercialize any such product candidates. For example, in March 2012, GSK voluntarily discontinued certain of its current clinical trials of GSK '052 but did not terminate the program. Following
its review, GSK may terminate the program and we would have to determine whether to continue to develop and commercialize that product candidate following its return to us.
If
our partner does not devote sufficient resources to the research, development and commercialization of compounds identified through our research collaboration, including GSK in the
case of GSK '052 and Lilly in the case of AN8194, or is ineffective in doing so, our operating results could be materially and adversely affected. In particular, if our partner independently develops
products that compete with our compounds, it could elect to advance such products and not develop or commercialize our product candidates, even while complying with applicable exclusivity provisions.
We cannot assure you that our collaboration partners will fulfill their obligations under the agreements or develop and commercialize compounds identified by the research collaborations, including GSK
in the case of GSK '052 and Lilly in the case of AN8194. If our partners fail to fulfill their obligations under the agreements or terminate the agreements, we would need to obtain the capital
necessary to fund the development and commercialization of the returned compounds, enter into alternative arrangements with a third party or halt our development efforts in these areas. We could also
become involved in disputes with our partners, which could lead to delays in or termination of the research collaborations or the development and commercialization of identified product candidates and
time-consuming and expensive litigation or arbitration. If our partners terminate or breach their agreements with us or otherwise do not advance the compounds identified by our research
collaborations, our chances of successfully developing or commercializing such compounds could be materially and adversely affected.
We may not be successful in establishing and maintaining development and commercialization collaborations, which could adversely affect our ability to develop certain of our
product candidates and our financial condition and operating results.
Developing pharmaceutical products, conducting clinical trials, obtaining regulatory approval, establishing manufacturing capabilities
and marketing approved products is expensive. Consequently, we plan to establish collaborations for development and commercialization of product candidates and research programs. For example, if
tavaborole, AN2728 or any of our other product candidates receives marketing approval, we intend to enter into sales and marketing arrangements with third parties for non-specialty markets
in the United States and for international sales, and to develop our own sales force targeting dermatologists and other specialty markets in the United States. If we are unable to enter into any such
arrangements on acceptable terms, if at all, we may be unable to market and sell our products in these markets. We expect to face competition in seeking appropriate collaborators. Moreover,
collaboration arrangements are complex and time consuming to negotiate, document and implement and they may require substantial resources to maintain. We may not be successful in our efforts to
establish and implement collaborations or other
alternative arrangements for the development of our product candidates. When we partner with a third party for development and commercialization of a product candidate, we can expect to relinquish
some or all of the control over the future success of that product candidate to the third party. Our collaboration partner may not devote sufficient resources to the commercialization of our product
candidates or may otherwise fail in their commercialization. The terms of any collaboration or other arrangement that we establish may not be favorable to us. In addition, any collaboration that we
enter into may be unsuccessful in the development and commercialization of our product candidates. In some cases, we may be responsible for continuing preclinical and initial clinical development of a
partnered product candidate or research program, and the payment we receive from our collaboration partner may be insufficient to cover the cost of this development. If we are unable to reach
agreements with suitable collaborators for our product candidates we would face increased costs, we may be forced to limit the number of our
51
Table of Contents
product
candidates we can commercially develop or the territories in which we commercialize them and we might fail to commercialize products or programs for which a suitable collaborator cannot be
found. If we fail to achieve successful collaborations, our operating results and financial condition will be materially and adversely affected.
We depend on third-party contractors for a substantial portion of our operations and may not be able to control their work as effectively as if we performed these functions
ourselves.
We outsource substantial portions of our operations to third-party service providers, including chemical synthesis, biological
screening and manufacturing. Our agreements with third-party service providers and clinical research organizations are on a study-by-study basis and are typically
short-term. In all cases, we may terminate the agreements with notice and are responsible for the supplier's previously incurred costs.
Because
we have relied on third parties, our internal capacity to perform these functions is limited. Outsourcing these functions involves risk that third parties may not perform to our
standards, may not produce results in a timely manner or may fail to perform at all. In addition, the use of third-party service providers requires us to disclose our proprietary information to these
parties, which could increase the risk that this information will be misappropriated. There is a limited number of third-party service providers that specialize or have the expertise required to
achieve our business objectives. Identifying, qualifying and managing performance of third-party service providers can be difficult, time consuming and cause delays in our development programs. We
currently have a small number of employees, which limits the internal resources we have available to identify and monitor our third-party
providers. To the extent we are unable to identify, retain and successfully manage the performance of third-party service providers in the future, our business may be adversely affected.
We have no experience manufacturing our product candidates on a large clinical or commercial scale and have no manufacturing facility. As a result, we are dependent on
numerous third parties for the manufacture of our product candidates and our supply chain, and if we experience problems with any of these suppliers, the manufacturing of our product candidates or
products could be delayed.
We do not own or operate facilities for the manufacture of our product candidates. We have a small number of personnel with experience
in drug product manufacturing. We currently outsource all manufacturing and packaging of our preclinical and clinical product candidates to third parties and intend to continue to do so. We will need
to scale up and manufacture additional active ingredient and drug product, potentially at other third party manufacturing sites, in order to complete our NDA submission for tavaborole. The inability
to manufacture sufficient supplies of the drug product could adversely affect, if tavaborole is approved, product commercialization. We also outsource active ingredient process development work and
product manufacturing to third parties for AN2728 and our other product candidates. We do not currently have any agreements with third-party manufacturers for the long-term commercial
supply of our product candidates, including tavaborole. We may encounter technical difficulties or delays in the transfer of tavaborole manufacturing on a commercial scale to a third-party
manufacturer. We may be unable to enter into agreements for commercial supply with third party manufacturers, or may be unable to do so on acceptable terms. We may not be able to establish additional
sources of supply for our products. Such suppliers are subject to regulatory requirements, covering manufacturing, testing, quality control and record keeping relating to our product candidates and
subject to ongoing inspections by the regulatory agencies. Failure by any of our suppliers to comply with applicable regulations may result in long delays and interruptions to our product candidate
supply while we seek to secure another supplier that meets all regulatory requirements.

Table of Contents
Reliance
on third-party manufacturers entails risks to which we would not be subject if we manufactured the product candidates ourselves,
including:
-
-
the possible breach of the manufacturing agreements by the third parties because of factors beyond our control; and
-
-
the possibility of termination or nonrenewal of the agreements by the third parties because of our breach of the
manufacturing agreement or based on their own business priorities.
Any
of these factors could cause the delay of clinical trials, regulatory submissions, required approvals or commercialization of our products, cause us to incur higher costs and prevent
us from commercializing our product candidates successfully. Furthermore, if any of our product candidates are approved and contract manufacturers fail to deliver the required commercial quantities of
finished product on a timely basis and at commercially reasonable prices and we are unable to find one or more replacement manufacturers capable of production at a substantially equivalent cost, in
substantially equivalent volumes and quality and on a timely basis, we would likely be unable to meet demand for our products and could lose potential revenue. It may take several years to establish
an alternative source of supply for our product candidates and to have any such new source approved by the FDA.
If we lose our relationships with contract research organizations, our drug development efforts could be delayed.
We are substantially dependent on third-party vendors and contract research organizations for preclinical studies and clinical trials
related to our drug discovery and development efforts. If we lose our relationship with any one or more of these providers, we could experience a significant delay in both identifying another
comparable provider and then contracting for its services, which could adversely affect our development efforts. We may be unable to retain an alternative provider on reasonable terms, if at all. Even
if we locate an alternative provider, it is likely that this provider will need additional time to respond to our needs and may not provide the same type or level of services as the original provider.
In addition, any contract research organization that we retain will be subject to the FDA's regulatory requirements and similar foreign standards and we do not have control over compliance with these
regulations by these providers. Consequently, if these practices and standards are not adhered to by these providers, the development and commercialization of our product candidates could be delayed,
which could severely harm our business and financial condition.
Risks Relating to Our Intellectual Property
It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.
Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection of our current
and future product candidates and the methods used to manufacture them, as well as successfully defending these patents against third-party challenges. Our ability to stop third parties from making,
using, selling, offering to sell or importing our products is dependent upon the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities.
The
patent positions of pharmaceutical companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. No
consistent policy regarding the breadth of claims allowed in pharmaceutical patents has emerged to date in the United States or in many foreign jurisdictions. Changes in either the patent laws or in
interpretations of patent laws in the United States and foreign jurisdictions may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be
enforced in the patents that may be issued from the applications we currently or may in the future own or license from third parties.
53
Table of Contents
Further,
if any patents we obtain or license are deemed invalid and unenforceable, it could impact our ability to commercialize or license our technology.
The
degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain
or keep our competitive advantage. For example:
-
-
others may be able to make compounds that are similar to our product candidates but that are not covered by the claims of
our patents;
-
-
we might not have been the first to make the inventions covered by our pending patent applications;
-
-
we might not have been the first to file patent applications for these inventions;
-
-
others may independently develop similar or alternative technologies or duplicate any of our technologies;
-
-
any patents that we obtain may not provide us with any competitive advantages;
-
-
we may not develop additional proprietary technologies that are patentable; or
-
-
the patents of others may have an adverse effect on our business.
As
of February 1, 2012, we are the owner of record of 12 issued U.S. patents and 7 non-U.S. patents with claims to boron-containing compounds and methods of using
these compounds in various indications. We are actively pursuing, either solely or with a collaborator, 28 U.S. patent applications (12 provisional and 20 non-provisional), 13
international (PCT) patent applications and 140 non-U.S. patent applications in at least 39 jurisdictions. Of these actively pursued applications, 1 international (PCT) patent application
and 3 non-U.S. patent applications are solely owned by a collaborator as of February 1, 2012.
Due
to the patent laws of a country, or the decisions of a patent examiner in a country, or our own filing strategies, we may not obtain patent coverage for all of the product candidates
or methods involving these candidates in the parent patent application. We plan to pursue divisional patent applications and/or continuation patent applications in the United States and many other
countries to obtain claim coverage for inventions which were disclosed but not claimed in the parent patent application.
Recently,
there have been numerous changes to the patent laws and proposed changes to the rules of the U.S. Patent and Trademark Office, or USPTO, which may have a significant impact on
our ability to protect our technology and enforce our intellectual property rights. For example, in September 2011,
President Obama signed the America Invents Act that codifies several significant changes to the U.S. patent laws, including, among other things, changing from a "first to invent' to a "first inventor
to file" system, limiting where a patent holder may file a patent suit, requiring the apportionment of patent damages, replacing interference proceedings with derivation actions, and creating a
post-grant opposition process to challenge patents after they have issued. The effects of these changes are currently unclear as the USPTO must still implement various regulations, the
courts have yet to address any of these provisions and the applicability of the act and new regulations on specific patents discussed herein have not been determined and would need to be reviewed.
We
also may rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to
protect. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, outside scientific collaborators and other advisors may unintentionally or willfully
disclose our information to competitors. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is
unpredictable. In addition, courts outside the
54
Table of Contents
United
States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. Our patent applications
would not prevent others from taking advantage of the chemical properties of boron to discover and develop new therapies, including therapies for the indications we are targeting. If others seek to
develop boron-based therapies, their research and development efforts may inhibit our ability to conduct research in certain areas and expand our intellectual property portfolio.
We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to enforce or
protect our rights to, or use, our technology.
If we choose to go to court to stop another party from using the inventions claimed in any patents we obtain, that individual or
company has the right to ask the court to rule that such patents are invalid or should not be enforced against that third party. These lawsuits are expensive and would consume time and resources and
divert the attention of managerial and scientific personnel even if we were successful in stopping the infringement of such patents. In addition, there is a risk that the court will decide that such
patents are not valid and that we do not have the right to stop the other party from using the inventions. There is also the risk that, even if the validity of such patents is upheld, the court will
refuse to stop the other party on the ground that such other party's activities do not infringe our rights to such patents. In addition, the U.S. Supreme Court has recently modified some tests used by
the U.S. Patent Office in granting patents over the past 20 years, which may decrease the likelihood that we will be able to obtain patents and increase the likelihood of challenge of any
patents we obtain or license.
Furthermore,
a third party may claim that we or our manufacturing or commercialization partners are using inventions covered by the third party's patent rights and may go to court to
stop us from engaging in our normal operations and activities, including making or selling our product candidates. These lawsuits are costly and could affect our results of operations and divert the
attention of managerial and scientific personnel. There is a risk that a court would decide that we or our commercialization partners are infringing the third party's patents and would order us or our
partners to stop the activities covered by the patents. In that event, we or our commercialization partners may not have a viable way around the patent and may need to halt commercialization of the
relevant product with it. In addition, there is a risk that a court will order us or our partners to pay the other party damages for having violated the other party's patents. In the future, we may
agree to indemnify our commercial partners against certain intellectual property infringement claims brought by third parties. The pharmaceutical and biotechnology industries have produced a
proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to
interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods either do not infringe the
patent claims of the relevant patent or that the patent claims are invalid, and we may not be able to do this. Proving invalidity is difficult. For example, in the United States, proving invalidity
requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents.
Because
some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign
jurisdictions are typically not published until eighteen months after filing, and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that
others have not filed patent applications for technology covered by our pending applications, or that we were the first to invent the technology. Our competitors may have filed, and may in the future
file, patent applications covering technology similar to ours. Any such patent application may have priority over our patent applications, which could further require us to obtain rights to issued
patents covering such technologies. If another party has filed a U.S. patent application on inventions similar to ours, we may have to participate in an
55
Table of Contents
interference
proceeding declared by the U.S. Patent and Trademark Office to determine priority of invention in the United States. The costs of these proceedings could be substantial, and it is
possible that such efforts would be unsuccessful if, unbeknownst to us, the other party had independently arrived at the same or similar invention prior to our own invention, resulting in a loss of
our U.S. patent position with respect to such inventions.
Patents
covering the composition of matter of tavaborole and AN2718 that were owned by others have expired. Our patent applications and patents include or support claims on other aspects
of tavaborole or AN2718, such as pharmaceutical formulations containing tavaborole or AN2718, methods of using tavaborole or AN2718 to treat disease and methods of manufacturing tavaborole or AN2718.
Without
patent protection on the composition of matter of tavaborole or AN2718, our ability to assert our patents to stop others from using or selling tavaborole or AN2718 in a
non-pharmaceutically acceptable formulation may be limited.
Some
of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any
uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.
We do not have exclusive rights to intellectual property we developed under U.S. federally funded research grants and contracts in connection with certain of our neglected
diseases initiatives, and, in the case of U.S. funded research, we could ultimately lose the rights we do have under certain circumstances.
Some of our intellectual property rights related to compounds that are not in clinical development as of February 1, 2012 were
initially developed in the course of research funded by the U.S. government. As a result, the U.S. government may have certain rights to intellectual property embodied in our current or future
products pursuant to the Bayh-Dole Act of 1980. Government rights in certain inventions developed under a government-funded program include a non-exclusive,
non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right to require us to grant exclusive licenses to
any of these inventions to a third party if they determine that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public
health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations. The U.S. government also has the right to take title to these
inventions if we fail to disclose the invention to the government and fail to file an application to register the intellectual property within specified time limits. In addition, the U.S. government
may acquire title in any country in which a patent application is not filed within specified time limits.
Some
of our intellectual property rights related to boron-containing compounds that are not in clinical development as of February 1, 2012 were developed through a collaboration
with the DNDi. We accept research funding from DNDi. We have a co-exclusive, royalty-free, sublicensable license with DNDi to make, use, import and manufacture a product for
treatment of human African trypanosomiasis, Chagas disease, and cutaneous and visceral leishmaniasis in humans in all countries of the world, specifically excluding Japan, Australia, New Zealand,
Russia, China, and all countries of North America and Europe, or DNDi Territory. We also grant to DNDi an exclusive, royalty-free, sublicensable license to distribute, including uses by,
or on behalf of, a public sector agency, a product containing molecules synthesized under the research plan for treatment of human African trypanosomiasis, Chagas disease, and cutaneous and visceral
leishmaniasis in humans in the DNDi Territory. As a result, we may not be able to realize any revenue in the DNDi Territory for any human therapeutics that we discover for these diseases. As of
February 1, 2012, the boron-containing compounds being studied in this collaboration are structurally distinct from our other clinical product candidates. As of February 1, 2012, none of
our other clinical product candidates are being considered for use in the DNDi collaboration.
56
Table of Contents
Some
of our intellectual property rights related to boron-containing compounds that are not in clinical development as of February 1, 2012 were developed through a collaboration
with Medicines for Malaria Venture, or MMV. We accept research and development funding from MMV, and we provide MMV with a worldwide, royalty-free non-exclusive license
(without the right to sublicense, except with prior Anacor written approval) to intellectual property rights arising under the collaboration to develop human therapeutics for the treatment of malaria
under the agreements. In September 2011, we amended the MMV agreements to include an exclusive license to GSK to further develop certain of the compounds under development through MMV. As of
February 1, 2012, the boron-containing compounds under development in this collaboration are structurally distinct from our clinical product candidates. As of February 1, 2012, none of
our clinical product candidates are being considered for use in the MMV collaboration.
Risks Related to Employee Matters and Managing Growth
We will need to expand our operations and increase the size of our company, and we may experience difficulties in managing growth.
As we increase the number of product development programs we have underway and advance our product candidates through preclinical
studies and clinical trials, we will need to increase our product development, scientific and administrative headcount to manage these programs. In addition, to meet our obligations as a public
company, we will need to increase our general and administrative headcount. Our management, personnel and systems currently in place may not be adequate to support this future growth. Our need to
effectively manage our operations, growth and various projects requires that we:
-
-
successfully attract and recruit new employees with the expertise and experience we will require;
-
-
manage our clinical programs effectively, which we anticipate being conducted at numerous clinical sites;
-
-
develop a marketing and sales infrastructure; and
-
-
continue to improve our operational, financial and management controls, reporting systems and procedures.
If
we are unable to successfully manage this growth, our business may be adversely affected.
We may not be able to manage our business effectively if we are unable to attract and retain key personnel.
We may not be able to attract or retain qualified management, finance, scientific and clinical personnel in the future due to the
intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in Northern California. If we are not able to attract and retain necessary personnel
to accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and our
ability to implement our business strategy.
Our
industry has experienced a high rate of turnover of management personnel in recent years. We are highly dependent on the development, regulatory, commercialization and business
development expertise of our executive officers and key employees. If we lose one or more of our executive officers or key employees, our ability to implement our business strategy successfully could
be seriously harmed. We have entered into change of control and severance agreements with each of our officers as part of our retention efforts. Replacing executive officers and key employees may be
difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to develop, gain regulatory approval
of and commercialize products successfully. Competition to hire from this limited pool is intense, and we may be unable to hire, train,
57
Table of Contents
retain
or motivate these additional key personnel. Our failure to retain key personnel could materially harm our business.
If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired, which would
adversely affect our business and our stock price.
We operate in an increasingly demanding regulatory environment, which requires us to comply with the Sarbanes-Oxley Act of 2002, or the
Sarbanes-Oxley Act, and the related rules and regulations of the Securities and Exchange Commission, expanded disclosure requirements, accelerated reporting requirements and more complex accounting
rules. Company responsibilities required by the Sarbanes-Oxley Act include establishing adequate internal control over financial reporting and disclosure controls and procedures. Effective internal
controls are necessary for us to produce reliable financial reports and are important to help prevent financial fraud. The growth of our operations and our initial public offering created a need for
additional resources within the accounting and finance functions in order to produce timely financial information and to create the level of segregation of duties customary for a U.S. public company.
Our
management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our
financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Our management does not expect that our internal
control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that
the control system's objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or
fraud will not occur or that all control issues and instances of fraud, if any, within our company will have been detected.
We
are required to comply with Section 404 of the Sarbanes-Oxley Act, or Section 404, in connection with this Annual Report on Form 10-K for the year
ending December 31, 2011. We have expended significant resources to develop the necessary documentation and testing procedures required by Section 404. We cannot be certain that the
actions we have taken to improve our internal control over financial reporting will be sufficient, and if we are unable to produce accurate financial statements on a timely basis, investors could lose
confidence in the reliability of our financial statements, which could cause the market price of our common stock to decline and make it more difficult for us to finance our operations and growth.
Other Risks Relating to Our Business
We face potential product liability exposure, and if successful claims are brought against us, we may incur substantial liability for a product candidate and may have to
limit its commercialization.
The use of our product candidates in clinical trials and the sale of any products for which we may obtain marketing approval expose us
to the risk of product liability claims. Product liability claims may be brought against us or our partners by participants enrolled in our clinical trials, patients, health care providers or others
using, administering or selling our products. If we cannot successfully defend ourselves against any such claims, we would incur substantial liabilities. Regardless of merit or eventual outcome,
product liability claims may result in:
-
-
withdrawal of clinical trial participants;
-
-
termination of clinical trial sites or entire trial programs;
-
-
costs of related litigation;
-
-
substantial monetary awards to patients or other claimants;
58
Table of Contents
-
-
decreased demand for our product candidates and loss of revenues;
-
-
impairment of our business reputation;
-
-
diversion of management and scientific resources from our business operations; and
-
-
the inability to commercialize our product candidates.
We
have obtained limited product liability insurance coverage for our clinical trials domestically and in selected foreign countries where we are conducting clinical trials. Our coverage
is currently limited to $5.0 million per occurrence and $5.0 million in the aggregate per year. As such, our insurance coverage may not reimburse us or may not be sufficient to reimburse
us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive, and, in the future, we may not be able to maintain insurance coverage at a reasonable cost
or in sufficient amounts to protect us against losses due to product liability. We intend to expand our insurance coverage for products to include the sale of commercial products if we obtain
marketing approval for our product candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for any products approved for marketing. Large
judgments have been awarded in class action lawsuits based on drugs that had unanticipated side effects. A successful product liability claim or series of claims brought against us, particularly if
judgments exceed our insurance coverage, could decrease our cash and adversely affect our business.
Our operations involve hazardous materials, which could subject us to significant liabilities.
Our research and development processes involve the controlled use of hazardous materials, including chemicals. Our operations produce
hazardous waste products. We cannot eliminate the risk of accidental contamination or discharge or injury from these materials. Federal, state and local laws and regulations govern the use,
manufacture, storage, handling and disposal of these materials. We could be subject to civil damages in the event of exposure of individuals to hazardous materials. In addition, claimants may sue us
for injury or contamination that results from our use of these materials and our liability may exceed our total assets. We have general liability insurance of up to $5.0 million per occurrence,
with an annual aggregate limit of $6.0 million, which excludes pollution liability. This coverage may not be adequate to cover all claims related to our biological or hazardous materials.
Furthermore, if we were to be held liable for a claim involving our biological or hazardous materials, this liability could exceed our insurance coverage, if any, and our other financial resources.
Compliance with environmental and other laws and regulations may be expensive and current or future regulations may impair our research, development or production efforts.
Our insurance policies are expensive and protect us only from some business risks, which will leave us exposed to significant uninsured liabilities.
We do not carry insurance for all categories of risk that our business may encounter. For example, we do not carry earthquake
insurance. In the event of a major earthquake in our region, our business could suffer significant and uninsured damage and loss. Some of the policies we currently maintain include general liability,
employment practices liability, property, auto, workers' compensation, products liability and directors' and officers' insurance. We do not know, however, if we will be able to maintain existing
insurance with adequate levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our cash position and results of operations.

Risks Relating to Owning Our Common Stock
Our executive officers, directors and principal stockholders have the ability to control all matters submitted to our stockholders for approval.
As of February 15, 2012 our executive officers, directors and stockholders who own more than 5% of our outstanding common stock,
together beneficially own shares representing approximately 68% of our common stock. As a result, if these stockholders were to choose to act together, they would be able to control all matters
submitted to our stockholders for approval, as well as our management and affairs. For example, these persons, if they choose to act together, will control the election of directors and approval of
any merger, consolidation, sale of all or substantially all of our assets or other business combination or reorganization. This concentration of voting power could delay or prevent an acquisition of
us on terms that other stockholders may desire. The interests of this group of stockholders may not always coincide with your interests or the interests of other stockholders and they may act in a
manner that advances their best interests and not necessarily those
of other stockholders, including seeking a premium value for their common stock, and might affect the prevailing market price for our common stock.
We do not anticipate paying cash dividends, and accordingly, stockholders must rely on stock appreciation for any return on their investment.
We do not anticipate paying cash dividends in the future. As a result, only appreciation of the price of our common stock, which may
never occur, will provide a return to stockholders. Investors seeking cash dividends should not invest in our common stock. In addition, our ability to pay cash dividends is currently prohibited by
the terms of our loan and security agreement with Oxford Finance LLC and Horizon Technology Finance Corporation.
Our share price may be volatile and could decline significantly.
The market price of shares of our common stock could be subject to wide fluctuations in response to many risk factors listed in this
section, and others beyond our control, including:
-
-
results of our clinical trials;
-
-
results of clinical trials of our competitors' products;
-
-
regulatory actions with respect to our products or our competitors' products;
-
-
actual or anticipated fluctuations in our financial condition and operating results;
-
-
actual or anticipated changes in our growth rate relative to our competitors;
-
-
actual or anticipated fluctuations in our competitors' operating results or changes in their growth rate;
-
-
competition from existing products or new products that may emerge;
-
-
announcements by us, our collaborators or our competitors of significant acquisitions, strategic partnerships, joint
ventures, collaborations or capital commitments;
-
-
issuance of new or updated research or reports by securities analysts;
-
-
fluctuations in the valuation of companies perceived by investors to be comparable to us;
-
-
share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;
-
-
additions or departures of key management or scientific personnel;
60
Table of Contents
-
-
disputes or other developments related to proprietary rights, including patents, litigation matters and our ability to
obtain patent protection for our technologies;
-
-
announcement or expectation of additional financing efforts;
-
-
sales of our common stock by us, our insiders or our other stockholders;
-
-
market conditions for biopharmaceutical stocks in general; and
-
-
general economic and market conditions.
Furthermore,
the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies.
These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political
and market conditions such as recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of shares of our common stock. You may not realize any
return on an investment in us and may lose some or all of your investment.
We may be subject to securities litigation, which is expensive and could divert management attention.
Our share price may be volatile, and in the past companies that have experienced volatility in the market price of their stock have
been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our
management's attention from other business concerns, which could seriously harm our business.
A significant portion of our total outstanding shares of common stock is restricted from immediate resale but may be sold into the market in the near future. This could
cause the market price of our common stock to drop significantly, even if our business is doing well.
As a result of our February 2012 public offering of common stock, sales of a substantial number of shares of our common stock in the
public market could occur in the future. These sales, or the perception in the market that the holders of a large number of shares of common stock intend to sell shares, could reduce the market price
of our common stock. Sales of shares of our common stock beneficially held by our directors and executive officers are currently restricted as a result of lock-up agreements but will be
able to be resold beginning upon expiration of the lock-up agreements, which will occur in May 2012, unless extended under certain circumstances. Moreover, holders of shares of our common
stock who are party to an investors' rights agreement and a registration rights agreement with us have rights, subject to some conditions, to require us to file registration statements covering their
shares or to include their shares in registration statements that we may file for ourselves or other stockholders.
As a public company we are subject to additional expenses and administrative burden.
As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company. In addition,
our administrative staff are required to perform additional tasks. For example, we must adopt additional internal controls and disclosure controls and procedures, retain a transfer agent and bear all
of the internal and external costs of preparing and distributing periodic public reports in compliance with our obligations under the securities laws.
In
addition, changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act and related regulations implemented by the
Securities and Exchange Commission and the NASDAQ Global Market, are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time
consuming. We are currently evaluating and monitoring these rules and proposed changes to rules, and
61
Table of Contents
cannot
predict or estimate the amount of additional costs we may incur or the timing of such costs. These laws, regulations and standards are subject to varying interpretations, in many cases due to
their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is
provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance
practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment will result in increased general and administrative expenses and may divert
management's time and attention from product development activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing
bodies due to ambiguities related to practice, regulatory authorities may initiate legal proceedings against us and our business may be harmed. In the future, it may be more expensive for us to obtain
director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for
us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.
Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more
difficult and may prevent attempts by our stockholders to replace or remove our current management.
Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition of us. In
addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our
board of directors, who are responsible for appointing the members of our management team. In addition, we are governed by the provisions of Section 203 of the Delaware General Corporation Law,
which prohibits, with some exceptions, stockholders owning in excess of 15% of our outstanding voting stock from merging or combining with us. Finally, our charter documents establish advanced notice
requirements for nominations for election to our board of directors and for proposing matters that can be acted upon at stockholder meetings. Although we believe these provisions together provide for
an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders.
ITEM 1B. UNRESOLVED STAFF COMMENTS
None.
ITEM 2. PROPERTIES
We lease a 36,960 square-foot building consisting of office and laboratory space in Palo Alto, California, which serves as
our corporate headquarters. The lease term commenced in March 2008 and has scheduled annual rent increases through the lease expiration in March 2018. We also have a lease for a 15,300
square-foot building consisting of office and laboratory space in Palo Alto, California, which we extended through December 2013, and have two (2) one-year options to
extend the lease through each of 2014 and 2015. This lease is cancelable with four months' notice. We believe that the facilities that we currently lease are adequate for our needs for the immediate
future and that, should it be needed, additional space can be leased to accommodate any future growth.
ITEM 3. LEGAL PROCEEDINGS
We are not currently a party to any material litigation or other material legal proceedings.
ITEM 4. MINE SAFETY DISCLOSURES
None.

The
closing price for our common stock as reported by The NASDAQ Global Market on February 29, 2012 was $5.94 per share.

and the number of shares used in the computation of the per share amounts. There is a lack of comparability in the per share amounts between the periods presented above. During the fourth quarter of
2010, we issued 12,000,000 shares of common stock sold in our initial public offering (IPO), 2,000,000 shares of common stock sold in a concurrent private placement, and 1,382,651 shares of common
stock sold pursuant to an over-allotment option granted to the underwriters of our IPO. Also during that quarter, all convertible preferred stock shares outstanding were converted into
11,120,725 shares of common stock at the closing of our IPO.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
You should read the following discussion and analysis together with our financial statements and the notes to
those statements included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. We use words such
as "may," "will," "expect," "anticipate," "estimate," "intend," "plan," "predict," "potential," "believe," "should" and similar expressions to identify forward-looking statements. These statements
appearing throughout this Annual Report on Form 10-K are statements regarding our intent, belief, or current expectations, primarily regarding our operations. You should not place
undue reliance on these forward-looking statements, which apply only as of the date of this Annual Report on Form 10-K. As a result of many factors, such as those set forth under
"Risk Factors" and elsewhere in this Annual Report on Form 10-K, our actual results may differ materially from those anticipated in these forward-looking
statements.
Overview
We are a biopharmaceutical company focused on discovering, developing and commercializing novel small-molecule therapeutics derived
from our boron chemistry platform. We have discovered, synthesized and developed seven molecules that are currently in development.
The
productivity of our internal discovery capability has enabled us to generate a pipeline of both topical and systemic boron-based compounds. We have discovered seven product
candidates that have reached development. Our lead product candidates include two topically administered dermatologic compoundstavaborole (formerly referred to as AN2690), an antifungal
for the treatment of onychomycosis, and AN2728, an anti-inflammatory for the treatment of atopic dermatitis and psoriasis. In addition, we have discovered three additional compounds that
we have out-licensed for further developmentGSK2251052, or GSK '052 (formerly referred to as AN3365), a systemic antibiotic for the treatment of infections caused by
Gram-negative bacteria that is licensed to GlaxoSmithKline LLC, or GSK, AN8194 for the treatment of an animal health indication that is licensed to Eli Lilly and Company, or Lilly
and AN5568, also referred to as SCYX-7158, for human African trypanosomiasis, or HAT, which is licensed to Drugs for Neglected Diseases initiative, or DNDi. Our most advanced product candidate is
tavaborole. We initiated our Phase 3 clinical trials for tavaborole in the fourth quarter of 2010 and completed enrollment for one of these two trials in November 2011 and the other in December
2011. For AN2728, we completed a Phase 2b dose-ranging trial in psoriasis in the second quarter of 2010, a second Phase 2b clinical trial in psoriasis in the second quarter
of 2011 and a Phase 1 absorption trial in the third quarter of 2011. We also completed a Phase 2a trial of AN2728 and AN2898, our second topical anti-inflammatory product
candidate, in mild-to-moderate atopic dermatitis in the fourth quarter of 2011. In early 2012, we completed two safety studies of AN2728, as well. Given the positive outcome
from our atopic dermatitis trial, the safety profile exhibited by AN2728 and the large unmet need in atopic dermatitis relative to psoriasis, we intend to focus our AN2728 development efforts on
atopic dermatitis in the near future and defer the start of the Phase 3 trial for psoriasis. In the second quarter of 2010, we completed a Phase 1 trial of GSK '052, and achieved
proof-of-concept as defined under our collaboration agreement with GSK. In the third quarter of 2010, GSK exercised its option to obtain an exclusive license to develop and
commercialize GSK '052. In the second quarter of 2011, GSK initiated two Phase 2 trials of GSK '052 in complicated urinary tract infections (cUTI) and complicated intra-abdominal
infections (cIAI). In March 2012, GSK voluntarily discontinued certain of its current clinical trials of GSK'052 due to a recently identified microbiological finding in a small number of patients in
the Phase 2b trial for the treatment of cUTI. While we believe the microbiological finding seen in the cUTI study is not related to the safety of GSK '052, the potential to negatively
impact efficacy led GSK to voluntarily discontinue that study as well as the Phase 2b study in cIAI and one of two Phase 1 studies in healthy volunteers. GSK is in the process of
obtaining and analyzing additional information from all enrolled subjects.

Table of Contents
In
addition to our three lead programs, we have two other clinical product candidates, AN2718 and AN2898, which are backup compounds to tavaborole and AN2728, respectively. We also have
two additional compounds we have licensed to partnersAN8194 that is licensed to Lilly for an animal health indication and AN5568 that is licensed to DNDi for sleeping sickness.
In
February 2007, we entered into an exclusive license, development and commercialization agreement with Schering Corporation, or Schering, for the development and worldwide
commercialization of tavaborole. Pursuant to the agreement, Schering paid us a $40.0 million non-refundable, non-creditable upfront fee and assumed sole responsibility
for development and commercialization of tavaborole. In November 2009, Schering merged with Merck & Co., Inc., or Merck, and in May 2010, we entered into a mutual termination and
release agreement with Merck. Under this agreement we regained the exclusive worldwide rights to tavaborole, Merck paid us $5.8 million and we released each other from any and all claims,
liabilities or other types of obligations under the 2007 agreement. Merck did not retain any rights to this compound.
In
October 2007, we entered into a research and development collaboration, option and license agreement with GSK for the discovery, development and worldwide commercialization of
boron-based systemic anti-infectives against four discovery targets. Pursuant to the agreement, GSK paid us a $12.0 million non-refundable, non-creditable
upfront fee in October 2007. In addition, GSK was obligated to make payments to us if certain development, regulatory and commercial events occurred on a compound-by-compound
basis and was further obligated to pay us tiered double-digit royalties with the potential to reach the mid-teens on annual net sales of products containing optioned compounds in
jurisdictions where there is a valid patent claim covering composition of matter or method of use of the product and lesser royalties for sales in jurisdictions where there is no such valid patent
claim. Such royalties shall continue until the later of expiration of such valid patent claims or ten years from the first commercial sale on a product-by-product and
country-by-country basis. GSK also invested $30.0 million in our preferred stock financing completed in December 2008. Subsequently, in November 2010, GSK invested an
additional $5.0 million in our common stock in connection with our initial public offering, or IPO. From execution of the agreement through December 31, 2011, in addition to the
$12.0 million upfront payment received in October 2007 and the $5.0 million upfront payment received in September 2011, or Amendment Fee, we have received $25.1 million for
achievement of specified milestones, including milestones related to GSK '052 for lead declaration, candidate selection, first patient dosing in a clinical trial and for GSK's exercise of its
option to obtain an exclusive license to develop and commercialize GSK '052. GSK has assumed responsibility for further development of GSK '052 and any resulting commercialization.
In
September 2011, we amended our research and development collaboration with GSK, the Master Amendment, to, among other things, give effect to certain rights in GSK '052 that
would be acquired by the U.S. government in connection with GSK's contract for government funding to support GSK's further development of GSK '052, provide GSK the option to extend its rights
around the bacterial enzyme target leucyl-tRNA synthetase, or LeuRS, as well as to add new research programs using our boron chemistry platform for tuberculosis, or TB, and malaria and,
should GSK elect to initiate it, an additional collaborative research program directed toward LeuRS. As a result of the Master Amendment, we received a $5.0 million Amendment Fee. We may also
receive additional milestone payments, bonus payments and research funding from GSK in the future. All such milestone
payments, bonus payments and research funding, once earned, would be non-refundable and non-creditable. We are also eligible to earn royalties on future sales of resulting
products. The Master Amendment terminated all previous activities under the original agreement, except GSK's activities related to GSK '052, which was licensed by GSK in July 2010 under the
original agreement. GSK retained sole responsibility for the further development and commercialization of GSK '052 and will continue to be obligated to make bonus payments to us, if certain
development and regulatory events occur and if certain sales levels for this drug are achieved, and to pay us royalties on annual net sales

of
GSK '052. Any future payment obligations of GSK with respect to the terminated activities under the original agreement, other than those related to GSK '052, were terminated and all
rights to the compounds developed as a result of such terminated activities, except those meeting specified criteria, reverted to us. The Master Amendment also terminated any research and development
obligations that we had with respect to the original agreement.
On
January 1, 2011, we adopted an accounting standard update that amended the guidance on accounting for arrangements with multiple deliverables and included new guidance
regarding how to apply the standard to arrangements that are materially modified following adoption of the update. Accordingly, we evaluated the terms of the September 2011 Master Amendment to our
research and development collaboration with GSK relative to the entire arrangement and determined the Master Amendment to be a material modification to the original agreement for financial reporting
purposes (see Note 8 to the financial statements). In analyzing this material modification, we determined that there were no undelivered elements remaining from the original agreement as of the
effective date of the Master Amendment and that the only undelivered element resulting from the Master Amendment, other than contingent deliverables, was the research services we are obligated to
provide under the new TB program. We also determined that the contractually agreed rates for the TB program research funding to be received from GSK approximates the fair value of the TB research
services and concluded, therefore, that the research funding rates were the best estimate selling price, or BESP, for the TB research services. Therefore, the estimated research funding still to be
received from GSK for these services would be sufficient to ensure the BESP amount is available for future revenue recognition. We then deducted the BESP amount from the sum of
(i) consideration currently committed to be received under the Master Amendment, including the TB research funding and the $5.0 million Amendment Fee and (ii) $4.2 million
in deferred revenue remaining from the original agreement as of the effective date of the Master Amendment and recognized the remainder of $9.2 million as revenue on the September 2011
modification date. We also determined that the adoption of the new accounting standard, and its guidance related to material modifications of arrangements, had a material impact on the revenues we
recognized from our collaboration with GSK. We recognized revenues from GSK of $10.8 million for the year ended December 31, 2011, and determined that the revenues for the same period
would have been $2.8 million if the GSK agreement, as modified by the Master Amendment, were still subject to the revenue recognition standards for multiple element arrangements that were in
effect prior to January 1, 2011.
In
August 2010, we entered into a collaboration agreement with Lilly, under which the companies are collaborating to discover products for a variety of animal health applications. Lilly
will be responsible for worldwide development and commercialization of compounds advancing from these efforts. We received a non-refundable, non-creditable upfront payment of
$3.5 million in September 2010 and will receive a minimum of $6.0 million in research funding with the potential of up to $12.0 million in research funding if successful. In
addition, we will be eligible to receive payments upon the achievement of specified development and regulatory milestones, as well as tiered royalties escalating from high single digit to in the tens
royalties on sales, depending in part upon the mix of products sold. In September 2011, we received a $1.0 million payment from Lilly upon the achievement of a development milestone.
In
February 2011, we entered into a collaboration agreement with Medicis. We received a $7.0 million upfront payment and are primarily responsible for discovering and conducting
early development of product candidates that utilize our proprietary boron chemistry platform. Medicis will have an option to obtain an exclusive license for products covered by the agreement. We will
be eligible for future payments of up to $153.0 million for the achievement of specified research, development, regulatory and sales goals, as well as tiered royalties on sales of licensed
products by Medicis or its sublicensees. Medicis will be responsible for further development and commercialization of the licensed products on a worldwide basis.

We
also have several collaborations with organizations that fund our research to leverage our boron chemistry to discover new treatments for neglected diseases. In addition to
potentially developing new therapies for the diseases, these collaborations provide us the potential benefits of expanding the chemical diversity of our boron compounds, understanding new properties
of our boron compounds, receiving future incentives, such as the potential grant of a priority review voucher by the FDA, and, ultimately if a drug is approved, potential revenue in some regions. Our
collaboration partners include DNDi to develop new therapeutics for HAT, visceral leishmaniasis and Chagas disease, MMV to develop compounds for the treatment of malaria, the Institute for OneWorld
Health to discover antibacterial compounds for treating diarrheal diseases and the Sandler Center for Drug Discovery at the University of California at San Francisco to discover new drug therapies for
the treatment of river blindness. In 2011, DNDi completed pre-clinical studies of AN5568 for HAT and in March 2012, AN5568 became the first compound from our neglected diseases initiatives
to enter human clinical trials.
We
began business operations in March 2002. To date, we have not generated any revenue from product sales and have never been profitable. As of December 31, 2011, we have an
accumulated deficit of $159.1 million. We have funded our operations primarily through the sale of equity securities, payments received under our agreements with Schering, GSK, Lilly and
Medicis, government contracts and grants, contracts with not-for-profit organizations for neglected diseases and borrowings under debt arrangements. We expect to incur losses
in future periods. The size of our future losses will depend, in part, on the rate of growth of our expenses, our ability to enter into
additional licensing, research and development agreements and future payments earned under our agreements with GSK, Lilly, Medicis or any such future collaboration partners. Our intent is to enter
into additional licensing and development agreements to further develop certain of our product candidates and to fund other areas of our research. If the GSK, Lilly and/or Medicis agreements are
terminated or we are unable to enter into other collaboration agreements, we may incur additional operating losses and our ability to expand and continue our research and development activities and
move our product candidates into later stages of development may be limited. We will need to seek additional capital through collaborations, equity offerings and debt financings to fund our
operations.
Financial Operations Overview
Revenues
Our recent revenues are comprised primarily of collaboration agreement-related revenues and government grants, while historically we
also had government contract revenues. Collaboration agreement-related revenues have included license fees, development reimbursements and development milestone fees. In addition, we received the
Amendment Fee in connection with our research and development collaboration with GSK, and a termination and release payment with respect to our previous agreement with Schering. Government grant
revenues have consisted of grant funding received from government entities and government contract revenues have included cost and cost plus fixed fee reimbursements for allowable costs.
We
have generated approximately $130.2 million in revenue from inception through December 31, 2011. Through 2004, we had recognized cumulative revenues of
$16.1 million through our contract with the U.S. Department of Defense for the development of antibiotics against infective anthrax. In September 2005, we were awarded a $1.0 million
National Institutes of Health, or NIH, grant for the identification of targets for certain antifungal compounds, which included work on the mechanism of action of tavaborole. In March 2007, we
received from Schering a $40.0 million upfront fee that was recognized ratably over the estimated period during which we performed development-related activities to transition tavaborole to
Schering. The estimated period was based on the research transition plan jointly developed by Schering and us. In addition to the upfront fee, we were paid for our development-related activities,
which included certain preclinical and clinical activities.
70
Table of Contents
Inception-to-date,
we have recognized revenue of $49.5 million under the Schering agreement, which was comprised of the full recognition of the $40.0 million
upfront fee and $9.5 million for our development-related transition activities. In November 2009, Schering merged with Merck and in May 2010, upon termination of the 2007 agreement, we regained
the exclusive worldwide rights to tavaborole and received a $5.8 million payment from Merck, which was recognized as revenue during 2010.
In
October 2007, we received a $12.0 million upfront fee under our agreement with GSK, which was being recognized ratably over the six-year research term. In September
2011, the remaining $4.2 million of deferred revenue was recognized upon the amendment of the contract. Through December 31, 2011, we recognized $43.3 million under this agreement
which was comprised of $12.0 million related to the upfront fee, $25.1 million for achievement of performance milestones, $5.0 million for the Amendment Fee, $0.2 million
related to reimbursement for the TB program and $1.0 million in reimbursement for patent costs, procurement of drug material and performance of certain clinical studies for GSK '052. In
the future, revenue under our agreement with GSK may include fees for our GSK product candidates achieving specified development, regulatory and sales goals and product royalties.
In
September 2010, we received a non-creditable, non-refundable upfront fee of $3.5 million under our agreement with Lilly, which we are recognizing over
the four-year research term on a straight-line basis. Under this agreement, we will receive a minimum of $6.0 million in research funding with the potential of up to
$12.0 million in research funding, if successful. Through December 31, 2011, we have recognized $6.4 million under this agreement, which was comprised of $1.2 million
related to the upfront fee, $4.2 million in research funding and $1.0 million for achievement of a development milestone.
In
October 2010, we were awarded $1.5 million from the United States Department of the Treasury under the Qualifying Therapeutic Discovery Project Program to support research for
six projects with the potential to produce new therapies. The full amount was recognized as government grant revenue in 2010.
In
February 2011, we received a non-creditable, non-refundable upfront fee of $7.0 million under our agreement with Medicis, which we are recognizing over
the six-year research term on a straight-line basis. Through December 31, 2011, we have recognized $1.0 million of the upfront fee.
From
inception through December 31, 2011, we have recognized $5.6 million of revenue for research relating to animal health indications and for research performed under our
agreements with not-for-profit organizations for neglected diseases.
Research and Development Expenses
Research and development expenses consist primarily of costs associated with research activities, as well as costs associated with our
product development efforts, including preclinical studies and clinical trials. Research and development expenses, including those paid to third parties, are recognized as incurred. Research and
development expenses include:
-
-
external research and development expenses incurred pursuant to agreements with third-party manufacturing organizations,
contract research organizations and investigational sites;
-
-
employee and consultant-related expenses, which include salaries, benefits, stock-based compensation and consulting fees;
-
-
third-party supplier expenses; and
71
Table of Contents
-
-
facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and
maintenance of facilities, amortization or depreciation of leasehold improvements, equipment and laboratory supplies and other expenses.
Our
expenses associated with preclinical studies and clinical trials are based upon the terms of the service contracts, the amount of the services provided and the status of the related
activities. We expect that research and development expenses will increase significantly in the future as we progress our product candidates through clinical development, conduct our research and
development activities
under our agreements with GSK, Lilly, Medicis and various current and potential collaborations, including those related to our neglected diseases initiatives, advance our discovery research projects
into the preclinical stage and continue our early-stage research.
The
table below sets forth our research and development expenses for 2011, 2010 and 2009, and for the period from January 1, 2004 through December 31, 2011, for four of our
clinical-stage product candidates, other work conducted under the GSK agreement, work on our Lilly and Medicis collaborations and work on neglected diseases and other programs, including programs that
are currently inactive. Prior to January 1, 2004, we did not separately track expenses for tavaborole or any other product candidates due to the early stage of their development. A portion of
our research and development costs, including indirect costs relating to our product candidates, are not tracked on a program-by-program basis and are allocated based on the
personnel resources assigned to each program.

We
expect our research and development expenses to increase in future periods. Our costs associated with tavaborole will increase as we will conduct additional clinical trials, in
addition to concluding our Phase 3 trials, and will perform additional regulatory activities in preparation for filing our NDA. We expect costs associated with AN2728 to increase as we expand
the clinical and preclinical activities for this program. Due to the option exercise by GSK for GSK '052 in July 2010, GSK has assumed all future development costs for this product candidate
and therefore our expenses associated with GSK '052 are expected to be minimal in the future. We also expect costs associated with our early stage research activities on our Lilly and Medicis
collaborations to increase in future periods. In addition, spending for our early-stage research programs, including our new GSK TB program and other potential GSK programs, will be dependent upon our
success in developing and advancing new product candidates for these programs.
We
cannot determine with certainty the duration and completion costs of the current or future clinical trials of our product candidates or if, when, or to what extent we will generate
revenues from
72
Table of Contents
the
commercialization and sale of any of our product candidates. We or our collaboration partners may never succeed in achieving marketing approval for any of our product candidates. The duration,
costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including the uncertainties of future clinical and preclinical studies, uncertainties
in clinical trial enrollment rates and significant and changing government regulation and whether our current or future collaborators are committed to and make progress in programs licensed to them.
For example, the timing to complete development of GSK '052 will be controlled by GSK because they have exercised their option to license this product candidate. In addition, the probability of
success for each product candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability. Consequently, we are unable to provide a meaningful
estimate of the period in which material cash inflows will be received. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success
of each product candidate, as well as an assessment of each product candidate's commercial potential.
Our
strategy includes entering into additional collaborations with third parties for the development and commercialization of some of our product candidates. To the extent that such
third parties have control over preclinical development or clinical trials for some of our product candidates, we will be dependent upon their efforts for the progress of such product candidates. We
cannot forecast with any degree of certainty which of our product candidates, if any, will be subject to future collaborations or how such arrangements would affect our development plans or capital
requirements.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries and related costs for our personnel, including stock-based
compensation and travel expenses, in executive, finance, business development and other administrative functions. Other general and administrative expenses include facility-related costs not otherwise
included in research and development expenses, consulting costs associated with financial services, professional fees for legal services, including patent-related expenses, and auditing and tax
services. We expect that general and administrative expenses will increase in the future as we expand our operating activities, hire additional staff and incur additional costs associated with
operating as a public company.
Critical Accounting Policies and Significant Judgments and Estimates
Our management's discussion and analysis of our financial condition and results of operations is based on our financial statements
included in this Annual Report on Form 10-K, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these
financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the
financial statements, as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments related to revenue recognition,
preclinical study and clinical trial accruals, deferred advance payments and stock-based compensation. We base our estimates on historical experience and on various other factors that we believe to be
reasonable under the circumstances and review our estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions.
While
our significant accounting policies are described in more detail in Note 2 of our financial statements included in this Annual Report on Form 10-K, we
believe the following accounting policies to be critical to the judgments and estimates used in the preparation of our financial statements.
73
Table of Contents
Revenue Recognition
Our contract revenues are generated primarily through research and development collaboration agreements, which typically may include
non-refundable, non-creditable upfront fees, funding for research and development efforts, payments for achievement of specified development, regulatory and sales goals and
royalties on product sales of licensed products.
For
multiple element arrangements, we evaluate the components of each arrangement as separate elements based on certain criteria. Where multiple deliverables are combined as a single
unit of accounting, revenues are recognized based on the performance requirements of the agreements. We recognize revenue when persuasive evidence of an arrangement exists; transfer of technology has
been completed, services are performed or products have been delivered; the fee is fixed or determinable; and collection is reasonably assured.
On
January 1, 2011, we adopted an accounting standard update that amends the guidance on accounting for arrangements with multiple deliverables. This update requires that each
deliverable be evaluated to determine whether it qualifies as a separate unit of accounting. This determination is generally based on whether the deliverable has stand-alone value to the customer.
This update also establishes a selling price hierarchy for determining how to allocate arrangement consideration to identified units of accounting. The selling price used for each unit of accounting
will be based on vendor-specific objective evidence, if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific
nor third-party evidence is available. Our management may be required to exercise considerable judgment in determining whether a deliverable is a separate unit of accounting and in estimating the
selling prices of identified units of accounting for new agreements. The update also provided new guidance regarding how to apply the standard to arrangements that are materially modified following
adoption of the update and our adoption of the update had a material impact on the revenues we recognized for the year ended December 31, 2011 as a result of the amended guidance being applied
to a material modification of our 2007 collaboration agreement with GSK in September 2011. The potential future impact of the adoption of this update will depend on the nature of any new arrangements
entered into or material modifications of existing arrangements.
Upfront
payments for licensing our intellectual property are evaluated to determine if the licensee can obtain stand-alone value from the license separate from the value of the research
and development services to be provided by us. Typically, we have determined that the licenses we have granted to collaborators do not have stand-alone value separate from the value of the research
and development services provided. As such, upfront payments are recorded as deferred revenue in the balance sheet and are recognized as contract revenue over the contractual or estimated performance
period that is consistent with the term of the research and development obligations contained in the research and development collaboration agreement. When stand-alone value is identified, the related
consideration is recorded as revenue in the period in which the license or other intellectual property rights are issued.
Some
arrangements involving the licensing of our intellectual property, the provision of research and development services or both may also include exclusivity clauses whereby we agree
that, for a specified period of time, we will not conduct further research on licensed compounds or on compounds that would compete with licensed compounds or that we will do so only on a limited
basis. Such provisions may also restrict the future development or commercialization of such compounds. We do not treat such exclusivity clauses as a separate element within an arrangement and any
upfront payments received related to the exclusivity clause would be allocated to the identified elements in the arrangement and recognized as described in the preceding paragraph.
Payments
resulting from our efforts under research and development agreements or government grants are recognized as the activities are performed and are presented on a gross basis.
Revenue is recorded gross because we act as a principal, with discretion to choose suppliers, bear credit risk and
74
Table of Contents
perform
part of the services. The costs associated with these activities are reflected as a component of research and development expense in our statements of operations and approximate the amount of
revenue recognized.
Also
on January 1, 2011, we adopted an accounting standard update that provides guidance on revenue recognition using the milestone method. This update established the milestone
method as an acceptable method of revenue recognition for certain contingent payments under research or development arrangements. Under the milestone method, a payment that is contingent upon the
achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. A milestone is an event (i) that can be achieved based in whole or in part
on either our performance or on the occurrence of a specific outcome resulting from our performance, (ii) for which there is substantive uncertainty at the date the arrangement is entered into
that the event will be achieved and (iii) that would result in additional payments being due to us. The determination that a milestone is substantive is judgmental and is made at the inception
of the arrangement. Milestones are considered substantive when the consideration earned from the achievement of the milestone is (i) commensurate with either our performance to achieve the
milestone or the enhancement of value of the item delivered as a result of a specific outcome resulting from our performance to achieve the milestone, (ii) relates solely to past performance
and (iii) is reasonable relative to all deliverables and payment terms in the arrangement. We have historically applied a milestone method approach to our research and development arrangements,
so the prospective adoption of this update did not have a material impact on our results of operations, cash flows or financial position.
Other
contingent payments received for which payment is either contingent solely upon the passage of time or the results of a collaboration partner's performance (bonus payments) are not
accounted for using the milestone method. Such bonus payments will be recognized as revenue when earned and when collectibility is reasonably assured.
Royalties
based on reported sales of licensed products will be recognized based on contract terms when reported sales are reliably measurable and collectibility is reasonably assured. To
date, none of our products have been approved and therefore we have not earned any royalty revenue from product sales.
Preclinical Study and Clinical Trial Accruals and Deferred Advance Payments
We estimate preclinical study and clinical trial expenses based on the services performed pursuant to contracts with research
institutions and clinical research organizations that conduct these activities on our behalf. In recording service fees, we estimate the time period over
which the related services will be performed and compare the level of effort expended through the end of each period to the cumulative expenses recorded and payments made for such services and, as
appropriate, accrue additional service fees or defer any non-refundable advance payments until the related services are performed. If the actual timing of the performance of services or
the level of effort varies from our estimate, we will adjust our accrual or deferred advance payment accordingly. If we underestimate or overestimate the level of services performed or the costs of
these services, our actual expenses could differ from our estimates. To date, we have not experienced significant changes in our estimates of preclinical study and clinical trial accruals.
Stock-Based Compensation
Employee stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as an
expense over the employee's requisite service period (generally the vesting period). Stock option awards granted to our nonemployee directors for their board-related services are included in employee
stock-based compensation in accordance with current accounting standards. We use the Black-Scholes option-pricing model to estimate the fair value of our stock-based
75
Table of Contents
awards
and use the straight-line (single-option) method for expense attribution. We estimate forfeitures and recognize expense only for those shares expected to vest.
We
account for equity instruments issued to nonemployees based on their fair values on the measurement dates using the Black-Scholes option-pricing model. The fair values of the options
granted to nonemployees are remeasured as they vest. As a result, the noncash charge to operations for nonemployee options with vesting is affected each reporting period by changes in the fair value
of our common stock.
We
recorded noncash stock-based compensation for employee and nonemployee stock option grants and ESPP stock purchase rights of $4.4 million, $2.8 million and
$2.5 million during 2011, 2010, and 2009, respectively. As of December 31, 2011, we had outstanding options to purchase 2,991,674 shares of our common stock and had $5.1 million
of unrecognized stock-based compensation expense, net of estimated forfeitures, related to outstanding stock options and $0.2 million related to ESPP stock purchase rights that will be
recognized over weighted-average periods of 2.6 and 0.6 years, respectively. There were 44,897 common shares purchased under the ESPP for the year ended December 31, 2011. We expect to
continue to grant stock options and ESPP stock purchase rights in the future, which will increase our stock-based compensation expense in future periods. If any of the assumptions used in the
Black-Scholes model change significantly, stock-based compensation expense may differ materially in the future from that recorded in the current period.

Contract revenue.
During 2011, we recognized the remaining $5.5 million of the upfront fee received from GSK in 2007, of which
$3.5 million was recognized as a result of the material modification of our GSK arrangement in September 2011, an additional $5.0 million amendment fee related to the additional rights
provided to GSK under the Master Amendment and $0.3 million for funding of our TB research activities and patent costs. We also recognized $3.1 million for research funding,
$1.0 million for a development milestone earned and $0.9 million of the upfront fee received under the Lilly agreement. Additionally, we recognized $1.0 million of the upfront fee
received under the Medicis agreement for the research services performed during the year and $3.5 million for work performed under other research and development agreements, including our
agreements with not-for-profit organizations for neglected diseases.
During
2010, we recognized $15.0 million for a development milestone earned under the collaboration with GSK, $0.9 million of revenue for reimbursement of patent and
clinical costs related to GSK '052 and $2.0 million of the upfront fee received from GSK in 2007. We also recognized revenue in 2010 for the $5.8 million payment that we received
from Merck upon the termination of the Schering license agreement. In addition, we recognized $1.1 million for research funding and $0.3 million of the upfront fee under the Lilly
agreement and $1.3 million of revenue for work we performed under research and development agreements, including under agreements with not-for-profit organizations for
neglected diseases.
Government grant revenue.
During 2010, we recognized the full $1.5 million of the Qualifying Therapeutic Discovery Project grant
funds awarded
to us in October 2010 by the United States Department of the Treasury for eligible investments we made in six of our projects during 2009 and 2010.
Research and development expenses.
The increase in research and development expenses for 2011 compared to 2010 was primarily due to the
increases in
manufacturing, development and clinical trial activities, which caused our expenses for tavaborole, AN2728 and AN2898 to increase by $17.3 million, $7.9 million and $2.9 million,
respectively. In the fourth quarter of 2010, we initiated our Phase 3 trials for tavaborole and completed enrollment of approximately 1,200 patients during 2011. During this period, we were
also manufacturing, packaging and labeling our clinical supplies for these trials and beginning our work to develop processes to manufacture the product in commercial quantities. In contrast, while we
began manufacturing clinical supplies and planning for our Phase 3 clinical trials in the second half of 2010, most of the activity in the first half of that year was administrative in nature.
As such, tavaborole expenses were significantly higher in 2011 than in 2010. For AN2728, our activities during 2011 consisted of enrolling patients and completing both our Phase 2b clinical
trial in psoriasis, our Phase 2 trial in atopic dermatitis and Phase 1 absorption trial, initiating two safety trials and conducting preclinical studies. This compared to fewer
AN2728-related activities in 2010, which consisted of conducting our initial Phase 2 trial for AN2728, completing preclinical studies and initiating manufacturing activities in
anticipation of starting additional preclinical studies and clinical trials. Our activities in 2011 for AN2898 consisted of enrolling patients in and completing our Phase 2 trial in atopic
dermatitis, manufacturing clinical supplies and conducting preclinical studies, which resulted in an increase in AN2898 expenses compared to 2010, during which our AN2898-related
activities were limited.
For
2011 compared to 2010, our research and development spending also increased by $1.8 million and $4.8 million under our contracts with Lilly and Medicis, respectively.
Our collaboration with Lilly was initiated in August 2010 and our collaboration with Medicis commenced in February 2011. In addition, spending on our neglected diseases initiatives increased by
$2.6 million in 2011 compared to 2010.
The
increases in expenses for our tavaborole, AN2728 and AN2898 programs and for the Lilly and Medicis collaborations were partially offset by decreases of $2.0 million and
$4.5 million in spending for
77
Table of Contents
GSK '052
and our other GSK programs, respectively. In 2010, we were conducting the Phase 1 clinical trial for GSK '052 at our own expense, whereas GSK is now solely responsible
for expenditures related to GSK '052 following their licensing of the compound in July 2010. In 2011, our activities on the other
GSK programs were reduced compared to 2010 due to the cessation of further development of compounds under these programs.
Our
efforts on our internal early-stage research projects decreased by $4.6 million in 2011 as compared with 2010 as we redirected our internal resources towards our collaborative
efforts with Medicis and Lilly. Our neglected diseases program expenses for 2011 increased by $2.6 million compared to 2010 as our efforts and funding on certain of these initiatives increased.
We
expect our research and development expenses to increase in the future as a result of increased development and clinical trial activity associated with our lead programs and our
continued efforts under our collaborations with GSK, Lilly and Medicis and for our neglected diseases initiatives. In particular, our clinical trial expenses will increase due to the initiation of
additional clinical trials and the conduct of our Phase 3 trial activities for tavaborole.
General and administrative expenses.
The increase in general and administrative expenses for 2011 as compared with 2010 was primarily
due to the
higher costs of operating as a public company. Our professional accounting and finance consulting fees, legal fees, board of directors compensation, directors and officers insurance and investor
relations expenses all increased. We also added additional staff in the latter part of 2010, including our Chief Financial Officer. Our noncash stock compensation expenses and consulting fees also
increased for 2011 as compared to 2010. These increases were only partially offset by lower patent-related legal fees as we allowed certain of our patents to lapse.
Interest income.
The rise in interest income for 2011 compared to 2010 was due to the increase in our investment balances as a result
of the proceeds
from our IPO in November 2010 and our debt drawdown in March 2011.
Interest expense and loss on early extinguishment of debt.
In March 2011, we drew down $10.0 million under our new loan facility
with Oxford
Finance LLC, or Oxford, and Horizon Technology Finance Corporation, or Horizon, and used $6.6 million of the proceeds to repay the remaining obligations under our loan facility with
Lighthouse Capital Partners V, L.P., or Lighthouse. In December 2011, we borrowed an additional $8.0 million. Interest expense decreased for 2011 compared to 2010 due to the lower
average effective interest rate on our new loan. Upon the early extinguishment of our Lighthouse debt in March 2011, we incurred a loss of $0.3 million, which consisted of the unaccrued portion
of the final payment, the unamortized portions of the debt discount and deferred issuance costs, plus a prepayment penalty.
Other income (expense).
The decrease in other income (expense) in 2011 compared to 2010 reflected the net reduction in the fair values
of our
preferred stock warrants during 2010. In connection with our IPO in November 2010, the preferred stock warrants automatically converted to common stock warrants, the related liability was reclassified
to additional paid-in capital and subsequent revaluations are no longer required.

Contract revenue.
During 2010, we recognized in full the $5.8 million fee that we received from Merck in connection with the
termination of
the Schering license agreement. We also recognized $2.0 million of the $12.0 million non-refundable, non-creditable upfront fee received from GSK,
$15.0 million for development milestones earned under this collaboration and $0.9 million of revenue for reimbursement of patent and clinical trial costs related to GSK '052. In
addition, we recognized $1.1 million for research funding and $0.3 million of the $3.5 million non-refundable, non-creditable upfront fee we received under
the Lilly agreement and $1.3 million of revenue for research performed under other agreements, including under agreements with not-for-profit organizations for neglected
diseases. During 2009, we recognized the final $8.7 million of the $40.0 million non-refundable, non-creditable, upfront fee under our license agreement with
Schering as we completed all development-related transition activities. We also recognized $0.3 million of revenue from these transition activities performed by us. We also recognized
$2.0 million of the upfront fee received from GSK and $6.8 million for development milestones earned. In addition, we recognized $0.8 million of
revenue for research performed under other agreements, including under agreements with not-for-profit organizations for neglected diseases.
Government grant revenue.
During 2010, we recognized the full $1.5 million of the Qualifying Therapeutic Discovery Project grant
funds awarded
to us in October 2010 by the United States Department of the Treasury for eligible investments we made in six of our projects during 2009 and 2010.
Research and development expenses.
The decrease in research and development expenses for 2010 compared to 2009 was primarily due to
decreases of
$9.3 million and $5.6 million in our other GSK programs and GSK '052, respectively. In the latter part of 2009, we redirected some of our resources away from our early-stage GSK
programs to focus our efforts more on GSK '052. This led to the reduction in spending on the other GSK programs in 2010. In 2009, we were in the midst of multiple development activities for
GSK '052 whereas during 2010, our activities were limited to conducting the Phase 1 clinical trial for this compound. Furthermore, GSK became solely responsible for expenditures related
to GSK '052 following their licensing of GSK '052 in July 2010. These two factors resulted in an overall reduction in GSK '052 expenses from 2009 to 2010.
Our
GSK program spending decreases were partially offset by increases of $4.5 million, $3.7 million and $3.0 million in our tavaborole, AN2728 and other research
programs, respectively. Due to Merck notifying us in January 2010 that they were terminating our licensing agreement with
79
Table of Contents
Schering,
we were actively transitioning tavaborole materials and documents from Schering back to us during 2010, as well as preparing to initiate the Phase 3 clinical trials, which commenced
in the fourth quarter of 2010. In contrast, during the prior year, we were winding down our tavaborole development work in anticipation of Schering beginning Phase 3 trials later that year.
During 2010, we were conducting our first Phase 2b trial for AN2728, completing some preclinical studies and initiating manufacturing activities in anticipation of starting additional
preclinical studies and our final Phase 2b clinical trial for AN2728 in psoriasis. This caused us to incur higher expenses for AN2728 in 2010 than during 2009 when we were winding down our
initial Phase 2b clinical trial and initiating startup activities for our final Phase 2b trial in psoriasis.
Our
efforts on our internal early-stage research projects increased during 2010 as compared to 2009 with increased expenses of $1.7 million for animal health-related research,
under our collaboration with Lilly, and $1.3 million more for other early-stage research projects.
General and administrative expenses.
The increase in general and administrative expenses in the 2010 as compared to 2009 was primarily
due to higher
stock-based compensation expenses, increased fees for audit services and an increase in bonus expenses as we achieved a higher percentage of our corporate goals in 2010 than in 2009. These increases
were only partially offset by lower corporate legal expenses.
Interest income.
The decrease in interest income was due to the reduction in investment balances and lower yields.
Interest expense.
Interest expense decreased in 2010 due to the lower outstanding balance on our debt and the increase in the term over
which we were
amortizing the final payment to Lighthouse and debt discounts as a result of our January 2010 loan restructuring. This decrease was partially offset by additional interest expenses associated with the
January 2010 loan restructuring in the form of accrued interest for the loan modification fee and amortization of the additional debt discount associated with the new warrant issued at that time.
Other income (expense).
The increase in other income (expense) in 2010 compared to 2009 reflected the net post-issuance reduction in
the
fair values of our preferred stock warrants during 2010 in contrast with 2009 when the fair values of these warrants increased.
Income Taxes
At December 31, 2011, we had net operating loss carryforwards for federal income tax purposes of $142.1 million and
federal research and development tax credit carryforwards of $6.2 million. Our utilization of the net operating loss and tax credit carryforwards may be subject to annual limitations due to the
ownership change limitations provided by the Internal Revenue Code and similar state provisions. The annual limitations may result in the expiration of net operating losses and credits prior to
utilization. We have determined that an ownership change, as defined by Internal Revenue Code Section 382, occurred in December 2010. However, the computed annual limitation is not expected to
prevent us from utilizing our net operating losses prior to their expiration if we can generate sufficient taxable income to do so in the future. We recorded a valuation allowance to offset in full
the benefit related to the deferred tax assets because realization of this benefit was uncertain.
Liquidity and Capital Resources
Since our inception, we have financed our operations primarily through our IPO in November 2010, private placements of equity
securities, funding from our agreements with Schering, GSK, Lilly and Medicis, government contract and grant funding and debt arrangements. We have also earned interest on our cash, cash equivalents
and short-term investments. At December 31, 2011, we had available cash and cash equivalents and short-term investments of $50.7 million.

Net
cash used in operating activities was $(35.7) million and $(3.2) million during 2011 and 2010, respectively. The net cash used in operating activities for 2011 primarily reflected
our net loss adjusted for noncash items, partially offset by changes in operating assets and liabilities, including the amortization of the remaining balance of the upfront fee received from GSK upon
the amendment of the contract and the increase in accrued liabilities due to our external development and clinical trial activities. Net cash from operations was also positively impacted by the
receipt of the $5.0 million Amendment Fee from GSK upon the execution of the Master Amendment of the research and development collaboration and by the $7.0 million upfront payment
received from Medicis, which resulted in an increase of $6.0 million in deferred revenue related to the Medicis contract. The net cash used in operating activities for 2010 resulted primarily
from our net loss adjusted for non-cash items and changes in operating assets and liabilities, including an increase in accrued liabilities due to increased preclinical and clinical
activities late in the year and payment of liabilities arising from our IPO. Cash used in operating activities was also positively affected by the $15.0 million payment received from GSK and
the $5.8 million received from Merck upon termination of our license agreement for tavaborole, both of which contributed to the lower net loss for the period. In addition, cash used in
operating activities for this period was also positively impacted by the $3.5 million upfront payment received from Lilly, which resulted in a $3.2 million increase in deferred revenue
related to our Lilly contract.
Net
cash provided by (used in) investing activities was $19.4 million and ($51.2) million for 2011 and 2010, respectively. The net cash provided by investing activities for 2011
was primarily related to the
proceeds from the maturities of investments offset by our purchases of investments. For 2010, the net cash used by investing activities was primarily the result of the purchases of
short-term investments as we invested the net proceeds from our IPO and our concurrent private placement.
Net
cash provided by financing activities was $9.7 million for 2011 compared with $67.5 million for 2010. The cash provided by financing activities for 2011 was primarily
due to the $18.0 million borrowing under our new loan facility with Oxford and Horizon, partially offset by the $8.1 million we paid for the regularly scheduled principal payments and
early extinguishment of our remaining obligations under our Lighthouse loan facility. The net cash provided by financing activities for 2010 was primarily a result of our IPO and concurrent private
placement of common stock which raised a combined $71.0 million partially offset by $3.1 million in principal payments on our notes payable and a loan restructuring fee payment of
$0.5 million to Lighthouse.
In
February 2012, we sold 3,250,000 shares of common stock for net proceeds of approximately $19.9 million. In addition, the underwriters were granted a 30-day option
to purchase up to an additional 487,500 shares of common stock to cover over-allotments, if any.
We
believe that our existing capital resources including the proceeds from the issuance of common stock in February 2012 and the remaining $12.0 million of borrowing capacity
under our loan facility with Oxford and Horizon will be sufficient to meet our anticipated operating requirements for at least the next twelve months. However, our forecast of the period of time
through which our financial
81
Table of Contents
resources
will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially.
Our
future capital requirements are difficult to forecast and will depend on many factors, including:
-
-
the initiation, progress, timing, costs and results of preclinical studies and clinical trials for our product candidates
and potential product candidates, including conduct of Phase 3 clinical trials for tavaborole and initiation and conduct of Phase 2 and Phase 3 clinical trials for AN2728;
-
-
the success of our collaborations with GSK, Lilly and Medicis and the attainment of contingent event-based payments and
royalties, if any, under those agreements;
-
-
the number and characteristics of product candidates that we pursue;
-
-
the terms and timing of any future collaboration, licensing or other arrangements that we may establish;
-
-
the outcome, timing and cost of regulatory approvals;
-
-
the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
-
-
the effect of competing technological and market developments;
-
-
the cost and timing of completion of commercial-scale outsourced manufacturing activities;
-
-
the cost of establishing sales, marketing and distribution capabilities for any product candidates for which we may
receive regulatory approval; and
-
-
the extent to which we acquire or invest in businesses, products or technologies.
If,
over the next several years, adequate funds are not available, we may be required to delay, reduce the scope of or eliminate some, or all of, the above activities.

We lease a 36,960 square-foot building in Palo Alto, California consisting of office and laboratory space which serves as
our corporate headquarters. The lease commenced in April 2008 and will terminate in March 2018.
We
also lease a 15,300 square-foot building consisting of office and laboratory space in Palo Alto, California. In October 2011, we amended this lease to extend the term to
December 31, 2013. In addition, we have two (2) one-year options to extend the lease through each of December 31, 2014 and 2015. The lease is cancelable with four
months' notice.
82
Table of Contents
In March 2011, we entered into a loan and security agreement, or Loan Agreement, with Oxford and Horizon, or the Lenders, to provide up
to $30.0 million, available in three tranches. The first $10.0 million tranche was drawn on March 18, 2011, at which time we repaid $6.6 million of the remaining
obligations under our previous loan facility with Lighthouse. The second and third tranches of $10.0 million each became available for drawdown upon our achieving full enrollment of the
Phase 3 trial for tavaborole in December 2011. We borrowed $8.0 million of the second tranche on December 28, 2011 and amended the Loan Agreement to revise the third tranche to
borrow up to an additional $12.0 million, which is available to us for drawdown through September 30, 2012. Payments on the loan are interest only until April 30, 2012 followed by
equal monthly payments of interest and principal through April 1, 2015. A final payment of $1.0 million will be due on April 1, 2015.
In
connection with the first and second tranche drawdowns in 2011, we issued warrants to the Lenders to purchase 80,257 and 88,997 shares, respectively, of our common stock (with an
aggregate exercise price equal to $1.1 million). The warrants are immediately exercisable, may be exercised on a cashless basis and expire seven years from the issuance date. We estimated the
total fair value of these two warrants using the Black-Scholes valuation model as of the issuance dates to be $0.7 million, which was recorded as a debt discount to the notes payable. If we
borrow any portion of the third tranche, we will issue additional warrants to the Lenders to purchase shares of our common stock equal to the number that results from dividing the lesser of $550,000
or 5.5% of the amount drawn by the exercise price for
the third tranche. The aggregate proceeds from the exercise of all warrants issued to the Lenders will not exceed $1.65 million.
From
January 1, 2011 to March 1, 2011, we made principal and interest payments to Lighthouse totaling $1.7 million prior to paying our remaining obligations of
$6.6 million from the proceeds of the first tranche borrowed under our new March 2011 loan and security agreement.
We enter into contracts in the normal course of business with clinical research organizations for clinical trials and clinical supply
manufacturing and with vendors for preclinical research studies, research supplies and other services and products for operating purposes. These contracts generally provide for termination on notice,
and therefore we believe that our non-cancelable obligations under these agreements are not material.
Off-Balance Sheet Arrangements
We currently have no off-balance sheet arrangements, such as structured finance, special purpose entities or variable
interest entities.
Recent Accounting Pronouncements
In May 2011, an amendment to an accounting standard was issued that amends the fair value measurement guidance and includes some
expanded disclosure requirements. The most significant change is the disclosure information required for Level 3 measurements based on unobservable inputs. This standard will become effective
for us on January 1, 2012 and is not expected to have a material impact on our financial statements.
In
June 2011, a new accounting standard was issued that eliminates the current option to report other comprehensive income and its components in the statement of stockholders' equity.
Instead, an entity will be required to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements. In December 2011, another
amendment to
defer certain requirements from the June 2011 guidance was issued that relates to the presentation of classification adjustments. This standard became effective retrospectively for us on
January 1, 2012. As this standard relates only to the presentation of other comprehensive income, the adoption of this accounting standard is not expected to significantly impact our financial
statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same
time maximizing the income we receive from our investments without significantly increasing risk. To achieve these objectives, our investment policy allows us to maintain a portfolio of cash
equivalents and short-term investments in a variety of high credit quality securities, including U.S. government instruments, commercial paper, money market funds and corporate debt
securities. Our investment policy prohibits us from holding auction rate securities or derivative financial instruments. To the extent that the investment portfolios of companies whose commercial
paper is included in our investment portfolio may be subject to interest rate risks, which could be negatively impacted by reduced liquidity in auction rate securities or derivative financial
instruments they hold, we may also be subject to these risks. However, our investments as of December 31, 2011 are comprised of U.S treasury securities, federal agency securities with a minimum
rating of AAA or A1, and U.S. government guaranteed corporate debt securities with a remaining average maturity of the entire portfolio of 56 days. Due to the short-term nature of
our investments, we believe that there is no material exposure to interest rate risk and we are not aware of any material exposure to market risk.

Report of Independent Registered Public Accounting Firm
The
Board of Directors and Stockholders
Anacor Pharmaceuticals, Inc.
We
have audited the accompanying balance sheets of Anacor Pharmaceuticals, Inc. (the Company) as of December 31, 2010 and 2011 and the related statements of operations,
convertible preferred stock and stockholders' equity (deficit) and cash flows for each of the three years in the period ended December 31, 2011. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.
We
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our opinion.
In
our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Anacor Pharmaceuticals, Inc. at December 31,
2010 and 2011, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2011, in conformity with U.S. generally accepted accounting
principles.
We
also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of
December 31, 2011, based on criteria established in
Internal ControlIntegrated Framework
issued by the Committee of Sponsoring
Organizations of the Treadway Commission and our report dated March 15, 2012 expressed an unqualified opinion thereon.
As
discussed in Note 2 to the financial statements, the Company changed its method of accounting for revenue recognition as a result of the adoption of the amendments to the FASB
Accounting Codification resulting from Accounting Standards Update No. 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements, effective January 1,
2011.

Notes to Financial Statements
1. The Company
Nature of Operation
Anacor Pharmaceuticals, Inc. (the Company) is a biopharmaceutical company focused on discovering, developing and commercializing
novel small-molecule therapeutics derived from its boron chemistry platform. The Company has discovered, synthesized and developed seven molecules that are currently in development. Its two lead
product candidates are topically administered dermatologic compoundstavaborole, formerly known as AN2690, an antifungal for the treatment of onychomycosis, and AN2728, an
anti-inflammatory for the treatment of atopic dermatitis and psoriasis. In addition, the Company has discovered three compounds that it has out-licensed for further
developmentGSK2251052 (GSK '052), formerly referred to as AN3365, a systemic antibiotic for the treatment of infections caused by Gram-negative bacteria that is licensed to
GlaxoSmithKline LLC (GSK), AN8194, a compound for the treatment of an animal health indication that is licensed to Eli Lilly and Company (Lilly) and AN5568, also referred to as SCYX-7158, for
human African trypanosomiasis, which is licensed to Drugs for Neglected Diseases initiative. The Company also has a pipeline of internally discovered topical and systemic boron-based compounds in
development.
The
Company has generated an accumulated deficit as of December 31, 2011 of approximately $159.1 million since inception, and will require substantial additional capital to
fund research and development activities, including clinical trials for its development programs and preclinical activities
for its product candidates. As of December 31, 2011, the Company believes that its cash, cash equivalents and marketable securities totaling approximately $50.7 million, and the net
proceeds of approximately $19.9 million from the February 2012 sale of 3,250,000 shares of the Company's common stock (see Note 16) and the remaining $12.0 million of borrowing
capacity under our loan facility (see Note 6), are sufficient to fund its operations through at least the next 12 months. The Company may also seek to raise funds through the sale of
equity or debt securities or through external borrowings. In addition, the Company may enter into additional collaborative arrangements or strategic partnerships for the development and
commercialization of its compounds. If, over the next several years, adequate funds are not available, the Company may be required to delay, reduce the scope of or eliminate one or more of its
development programs.
2. Summary of Significant Accounting Policies
Use of Estimates
The preparation of the financial statements in accordance with U.S. generally accepted accounting principles requires the Company to
make estimates and judgments in certain circumstances that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. In
preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. On an
ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, fair values of financial instruments in which we invest, notes payable, income taxes, preclinical
study and clinical trial accruals and other contingencies. Management bases its estimates on historical experience or on various other assumptions that it believes to be reasonable under the
circumstances. Actual results could differ from these estimates.

Reclassifications
As of December 31 2011, GSK was no longer considered a related party (See Note 8). As a result, certain prior year
amounts have been reclassified to conform to the current year presentation. Prior year line item classifications included contract receivablerelated party and accrued
liabilitiesrelated party in the balance sheets and contract revenuerelated party in the statements of operations. There was no impact to the previously reported total
revenue, operating loss or net loss or total assets, liabilities or stockholders' equity as a result of the reclassifications.
Cash, Cash Equivalents and Short-Term Investments
The Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash and cash
equivalents. Investments with a maturity date of more than three months, but less than twelve months, from the date of purchase are considered short-term investments and are classified as
current assets. The Company's short-term investments in marketable securities are classified as available for sale (see Note 3). Securities available for sale are carried at
estimated fair value, with unrealized gains and losses reported as part of accumulated other comprehensive income or loss, a separate component of stockholders' equity. The Company has estimated the
fair value amounts by using available market information. The cost of available-for-sale securities sold is based on the specific-identification method.
Fair Value of Financial Instruments
The carrying amounts of certain of the Company's financial instruments, including cash and cash equivalents, short-term
investments, restricted investments, contract receivables and accounts payable, approximate their fair value due to their short maturities. Based on the borrowing rates available to the Company for
loans with similar terms and average
maturities, the carrying value of the Company's long-term notes payable approximate their fair values as of December 31, 2011 and 2010.
Fair
value is considered to be the price at which an asset could be exchanged or a liability transferred (an exit price) in an orderly transaction between knowledgeable, willing parties
in the principal or most advantageous market for the asset or liability. Where available, fair value is based on or derived from observable market prices or other observable inputs. Where observable
prices or inputs are not available, valuation models are applied. These valuation techniques involve management estimation and judgment, the degree of which is dependent on the price transparency for
the instruments or market and the instruments' complexity.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents,
short-term investments and restricted investments. Substantially all the Company's cash, cash equivalents and restricted investments are held by two financial institutions that management
believes are of high credit quality. Such deposits may, at times, exceed federally insured limits. As of December 31, 2011 and 2010, 82% and 62%, respectively, of the cash and cash equivalents
were held in a money market fund invested in U.S. Treasuries, securities guaranteed as to principal and interest by the U.S. government and repurchase agreements in respect of such securities. The
Company's short-term investments as of December 31, 2011 and 2010 were held in securities guaranteed as to principal and interest by the U.S. government. During the three years
ended

Notes to Financial Statements (Continued)
2. Summary of Significant Accounting Policies (Continued)
December 31,
2011, the Company has not experienced any losses on its deposits of cash, cash equivalents, short-term investments and restricted investments and management believes
that its guidelines for investment of its excess cash maintain safety and liquidity through diversification and investment maturity.
Customer Concentration
The Company's revenues consist primarily of contract revenue from collaboration agreements with GSK, Lilly and a development agreement
with Medicines for Malaria Venture (MMV) (see Note 8). Collaborators have accounted for significant revenues in the past and may not provide contract revenues in the future under existing
agreements and/or new collaboration agreements, which may have a material effect on the Company's operating results.
Contract
revenue that accounted for 10% or more of total revenues was as follows:

Contract Receivable
The Company's contract receivables are primarily composed of amounts due under collaboration agreements and the Company believes that
the credit risks associated with these collaborators are not significant. During the three years ended December 31, 2011, the Company has not written-off any contract receivables
and, accordingly, does not have an allowance for doubtful accounts as of December 31, 2011 and 2010.
Restricted Investments
Under its facility lease agreements, the Company is required to secure letters of credit. As of December 31, 2011 and 2010, the
Company had approximately $0.2 million of restricted investments to secure these letters of credit.
Property and Equipment
Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are calculated
using the straight-line method over the estimated useful lives of the respective assets, generally three to five years. Leasehold improvements are amortized over the shorter of the
remaining lease term or the estimated useful economic lives of the related assets.

2. Summary of Significant Accounting Policies (Continued)
Impairment of Long-Lived Assets
Losses from impairment of long-lived assets used in operations are recorded when indicators of impairment are present and
the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amounts. The Company regularly evaluates its long-lived assets for indicators of
possible impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss would be recognized when
estimated undiscounted future cash flows expected to result from the use of an asset and its eventual disposition are less than its carrying amount. Impairment, if any, is assessed using discounted
cash flows.
Revenue Recognition
The Company's contract revenues are generated primarily through research and development collaboration agreements, which typically may
include non-refundable, non-creditable upfront fees, funding for research and development efforts, payments for achievement of specified development, regulatory and sales goals
and royalties on product sales of licensed products.
For
multiple element arrangements, the Company evaluates the components of each arrangement as separate elements based on certain criteria. Where multiple deliverables are combined as a
single unit of accounting, revenues are recognized based on the performance requirements of the agreements. The Company recognizes revenue when persuasive evidence of an arrangement exists; transfer
of technology has been completed, services are performed or products have been delivered; the fee is fixed or determinable; and collection is reasonably assured.
On
January 1, 2011, the Company adopted an accounting standard update that amends the guidance on accounting for arrangements with multiple deliverables. This update requires that
each deliverable be evaluated to determine whether it qualifies as a separate unit of accounting. This determination is generally based on whether the deliverable has stand-alone value to the
customer. This update also establishes a selling price hierarchy for determining how to allocate arrangement consideration to identified units of accounting. The selling price used for each unit of
accounting will be based on vendor-specific objective evidence, if available, third-party evidence if vendor-specific objective evidence is not available or estimated selling price if neither
vendor-specific nor third-party evidence is available. Management may be required to exercise considerable judgment in determining whether a deliverable is a separate unit of accounting and in
estimating the selling prices of identified units of accounting for new agreements. The adoption of the update had a material impact on the revenues recognized by the Company for the year ended
December 31, 2011 as a result of the amended guidance being applied to a material modification of the Company's 2007 collaboration agreement with GSK in September 2011
(see Note 8). The potential future impact of the adoption of this update will depend on the nature of any new arrangements entered into or material modifications of existing arrangements.
Upfront
payments for licensing the Company's intellectual property are evaluated to determine if the licensee can obtain stand-alone value from the license separate from the value of the
research and development services to be provided by the Company. Typically, the Company has determined that the licenses it has granted to collaborators do not have stand-alone value separate from the
value of the research and development services provided. As such, upfront payments are recorded as deferred revenue in the balance sheet and are recognized as contract revenue over the contractual or
estimated
94

2. Summary of Significant Accounting Policies (Continued)
performance
period that is consistent with the term of the research and development obligations contained in the research and development collaboration agreement. When stand-alone value is identified,
the related consideration is recorded as revenue in the period in which the license or other intellectual property rights are issued.
Some
arrangements involving the licensing of the Company's intellectual property, the provision of research and development services or both may also include exclusivity clauses whereby
the Company agrees that, for a specified period of time, it will not conduct further research on licensed compounds or on compounds that would compete with licensed compounds or that it will do so
only on a limited basis. Such provisions may also restrict the future development or commercialization of such compounds. The Company does not treat such exclusivity clauses as a separate element
within an arrangement and any upfront payments received related to the exclusivity clause would be allocated to the identified elements in the arrangement and recognized as described in the preceding
paragraph.
Payments
resulting from the Company's efforts under research and development agreements or government grants are recognized as the activities are performed and are presented on a gross
basis. Revenue is recorded gross because the Company acts as a principal, with discretion to choose suppliers, bears credit risk and performs part of the services. The costs associated with these
activities are reflected as a component of research and development expense in the statements of operations and approximate revenue recognized.
Also
on January 1, 2011, the Company adopted an accounting standard update that provides guidance on revenue recognition using the milestone method. This update established the
milestone method as an acceptable method of revenue recognition for certain contingent payments under research or development arrangements. Under the milestone method, a payment that is contingent
upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. A milestone is an event (i) that can be achieved based in whole
or in part on either the Company's performance or on the occurrence of a specific outcome resulting from the Company's
performance, (ii) for which there is substantive uncertainty at the date the arrangement is entered into that the event will be achieved and (iii) that would result in additional
payments being due to the Company. The determination that a milestone is substantive is judgmental and is made at the inception of the arrangement. Milestones are considered substantive when the
consideration earned from the achievement of the milestone is (i) commensurate with either the Company's performance to achieve the milestone or the enhancement of value of the item delivered
as a result of a specific outcome resulting from the Company's performance to achieve the milestone, (ii) relates solely to past performance and (iii) is reasonable relative to all
deliverables and payment terms in the arrangement. The Company has historically applied a milestone method approach to its research and development arrangements, so the prospective adoption of this
update did not have a material impact on its results of operations, cash flows or financial position.
Other
contingent payments received for which payment is either contingent solely upon the passage of time or the results of a collaborative partner's performance (bonus payments) are not
accounted for using the milestone method. Such bonus payments will be recognized as revenue when earned and when collectibility is reasonably assured.
Royalties
based on reported sales of licensed products will be recognized based on contract terms when reported sales are reliably measurable and collectibility is reasonably assured. To
date, none of
95

the
Company's products have been approved and therefore the Company has not earned any royalty revenue from product sales.
Research and Development Expenses
All research and development expenses, including those funded by third parties, are expensed as incurred. Research and development
expenses include, but are not limited to, salaries, benefits, stock-based compensation, lab supplies, allocated overhead, fees for professional service providers and costs associated with product
development efforts, including preclinical studies and clinical trials.
Preclinical Study and Clinical Trial Accruals and Deferred Advance Payments
The Company estimates preclinical study and clinical trial expenses based on the services performed pursuant to contracts with research
institutions and clinical research organizations that conduct these activities on its behalf. In recording service fees, the Company estimates the time period over which the related services will be
performed and compares the level of effort expended through the end of each period to the cumulative expenses recorded and payments made for such services and, as appropriate, accrues additional
service fees or defers any non-refundable advance payments until the related services are performed. If the actual timing of the performance of services or the level of effort varies from
the estimate, the Company will adjust its accrual or deferred advance payment accordingly. If the Company later determines that it no longer expects the services associated with a deferred
non-refundable advance payment to be rendered, the deferred advance payment will be charged to expense in the period that such determination is made.
Fair Values of Preferred Stock Warrants and Common Stock Warrants
Prior to the Company's IPO in November 2010, outstanding warrants to purchase shares of its convertible preferred stock were
freestanding warrants that were exercisable into convertible preferred stock that was subject to redemption and were therefore classified as liabilities in the balance sheet at fair value. The initial
liability recorded was adjusted for changes in the fair values of the Company's preferred stock warrants during each reporting period and was recorded as a component of other income (expense) in the
statement of operations for that period.
Upon
closing of the Company's IPO and the conversion of the underlying preferred stock to common stock, all outstanding warrants to purchase shares of preferred stock were automatically
converted into warrants to purchase shares of the Company's common stock. The aggregate fair value of these warrants upon the closing of the IPO was $0.4 million which was reclassified from
liabilities to additional paid-in capital, a component of stockholders' equity, and the Company ceased recording any related periodic fair value adjustments. The Company estimated the fair
values of these warrants using the Black-Scholes option-pricing model, based on the inputs for the estimated fair value of the underlying convertible preferred stock at the valuation measurement date,
the remaining contractual term of the warrant, risk-free interest rates, expected dividend rates and expected volatility of the price of the underlying convertible preferred stock. These
estimates were based on subjective assumptions.
The
Company estimates the fair value of common stock warrants using the Black-Scholes option-pricing model, based on the inputs for the fair value of the underlying common stock at the
valuation
measurement date, the remaining contractual term of the warrant, risk-free interest rates, expected

2. Summary of Significant Accounting Policies (Continued)
dividend
rates and expected volatility of the price of the underlying common stock. These estimates were based on subjective assumptions.
Stock-Based Compensation
Employee stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as an
expense over the employee's requisite service period (generally the vesting period). Stock option awards granted to the Company's nonemployee directors for their board-related services are included in
employee stock-based compensation in accordance with current accounting standards. The Company uses the Black-Scholes option-pricing model to estimate the fair value of its stock-based awards and uses
the straight-line (single-option) method for expense attribution. The Company estimates forfeitures and recognizes expense only for those shares expected to vest.
The
Company accounts for equity instruments issued to nonemployees based on their fair values on the measurement dates using the Black-Scholes option-pricing model. The fair values of
the options granted to nonemployees are remeasured as they vest. As a result, the noncash charge to operations for nonemployee options with vesting is affected each reporting period by changes in the
fair value of the Company's common stock.
Income Taxes
The Company utilizes the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are
determined based on differences between financial reporting and tax reporting bases of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when
the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.
The
Company recorded a full valuation allowance at each balance sheet date presented. Based on the available evidence, the Company believes that it is more likely than not that it will
be unable to utilize all of its deferred tax assets in the future. The Company intends to maintain the full valuation allowances until there is sufficient evidence to support the reversal of the

The
Company accounts for uncertain tax positions in the financial statements when it is more likely than not that the position will be sustained upon examination by the tax authorities.
Such tax positions must initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax
authority assuming full knowledge of the position and relevant facts. The Company's policy is to recognize any interest and penalties related to income taxes in income tax expense.
Net Loss per Common Share
Basic net loss per common share is calculated by dividing the net loss by the weighted-average number of common shares outstanding
during the period, without consideration for common stock equivalents. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents
outstanding for the period determined using the treasury-stock method. For purposes of this calculation, potentially dilutive securities consisting of convertible

Comprehensive Loss
Comprehensive loss and its components are reported in the statements of convertible preferred stock and stockholders' equity (deficit).
Comprehensive loss consists of net loss and unrealized gains or losses on marketable securities.
Recent Accounting Pronouncements
In May 2011, an amendment to an accounting standard was issued that amends the fair value measurement guidance and includes some
expanded disclosure requirements. The most significant change is the disclosure information required for Level 3 (see Note 3) measurements based on unobservable inputs. This standard
will become effective for the Company on January 1, 2012 and is not expected to have a material impact on the Company's financial statements.
In
June 2011, a new accounting standard was issued that eliminates the current option to report other comprehensive income and its components in the statement of stockholders' equity.
Instead, an entity will be required to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements. In December 2011, another
amendment to defer certain requirements from the June 2011 guidance was issued that relates to the presentation of reclassification adjustments. This standard became effective retrospectively for the
Company on January 1, 2012. As this accounting standard relates only to the presentation of other comprehensive income, the adoption of the standard is not expected to significantly impact the
Company's financial statements.

All
marketable securities held as of December 31, 2011 and 2010 had maturities at the date of purchase of less than one year.
The
Company recognized gross realized gains of $4,000 in 2009 from the sale of marketable securities. There were no realized gains or losses recognized from the sale of marketable
securities in 2011 or 2010.
In
measuring fair value, the Company evaluates valuation techniques such as the market approach, the income approach and the cost approach. A three-level valuation hierarchy that
prioritizes the inputs to valuation techniques is used to measure fair value based upon whether such inputs are observable or unobservable.

3. Marketable Securities and Fair Value Measurements (Continued)
Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for
the inputs to valuation techniques is briefly summarized as follows:
-
-
Level 1Observable inputs such as quoted prices (unadjusted) for
identical
instruments in active markets;
-
-
Level 2Observable inputs such as quoted prices for
similar
instruments in active markets, quoted prices for identical
or similar instruments in markets that are not active, or model-derived valuations
whose significant inputs are observable; and
-
-
Level 3Unobservable inputs that reflect the reporting entity's own assumptions.

The
Company's valuation technique to measure the fair value of the preferred stock warrants liability was based on valuations prepared by the Company, with the assistance of independent
consultants, using unobservable inputs, including the Company's assumptions about projected revenues, expenses, cash flows, risk-based rates of return on projected cash flows, expected
volatility and marketability discounts applicable to the Company's common and convertible preferred stock. The Company remeasured the fair value of the preferred stock warrants liability at each
reporting period using current assumptions, with changes in fair value recorded as other income (expense). The preferred stock warrants liability was reclassified to additional paid-in
capital, a component of stockholders' equity subsequent to the Company's IPO in November 2010 (see Note 10).

6. Notes Payable
In March 2011, the Company entered into a loan and security agreement with Oxford Finance LLC and Horizon Technology Finance Corporation (the Lenders) to provide up to
$30.0 million available in three tranches of $10.0 million each (the Loan Agreement). The first $10.0 million tranche was drawn at the closing of the transaction, at which time
the Company repaid $6.6 million of the remaining obligations
under its previous loan. The second and third tranches of $10.0 million each became available for drawdown upon the Company's full enrollment of its Phase 3 trials for tavaborole in
December 2011. The Company borrowed $8.0 million of the second tranche in December 2011 and the Company and the Lenders amended the Loan Agreement to revise the third tranche to
$12.0 million, which is available for drawdown through September 30, 2012. The interest rate for each tranche will be fixed upon drawdown at a rate equal to the greater of 9.4% or 9.1%
plus the 3-month U.S. LIBOR rate. Beginning April 1, 2011, payments under the Loan Agreement are interest only until April 30, 2012 followed by equal monthly payments of
interest and principal through April 1, 2015. In addition, a final payment equal to 5.5% of the amounts drawn ($990,000 for the first and second tranches) will be due on the earlier of
April 1, 2015, or such earlier date specified in the Loan Agreement. The Company paid the Lenders financing fees of $0.3 million and incurred legal fees of $0.1 million in
connection with the loan. These fees are being accounted for as a debt discount and deferred debt issuance costs, respectively.
The
Loan Agreement includes standard affirmative and restrictive covenants, but does not include any covenants to attain or maintain any specific financial metrics, and also includes
standard events of default, including payment defaults, breaches of covenants following any applicable cure period, a material impairment in the perfection or priority of the Lenders' security
interest or in the value of the collateral and a material impairment of the prospect of repayment of the loans. Upon the occurrence of an event of default and following any applicable cure periods, a
default interest rate of an additional 5% may be applied to the outstanding loan balances, and the Lenders may declare all outstanding obligations immediately due and payable and take such other
actions as set forth in the Loan Agreement.
The
loan is secured by all assets of the Company except intellectual property. Under the Loan Agreement, the Company also agreed to certain restrictions regarding the pledging or
encumbrance of its intellectual property.
In
connection with the Loan Agreement and the first and second tranche drawdown of $10.0 and $8.0 million, the Company issued warrants to the Lenders to purchase 80,527 shares and
88,997 shares, respectively, of its common stock (with an aggregate exercise price equal to $1.1 million) The warrants
102

are
immediately exercisable and may be exercised on a cashless basis. The aggregate fair value of the warrants issued was approximately $0.7 million and was calculated using a Black-Scholes
valuation model with the following assumptions: risk-free interest rate based upon observed risk-free interest rates appropriate for the expected term of the warrants; expected
volatility based on the average historical volatilities of a peer group of publicly-traded companies within the Company's industry; expected term equal to the contractual life of the warrants; and a
dividend yield of 0%.

In
connection with the issuance of warrants to the Lenders during 2011, the Company recorded debt discounts totaling $0.7 million. If the Company borrows any portion of the third
tranche, it will issue additional warrants to the Lenders to purchase a number of shares equal to the number that results from dividing the lesser of $550,000 or 5.5% of the amount drawn by the
exercise price for the third tranche, which will be the lower of the price per share of the Company's common stock on the day prior to drawdown or the average share price for the ten days preceding
the drawdown. The aggregate proceeds from the exercise of all warrants issued to the Lenders will not exceed $1.65 million.
The
Company granted certain piggyback registration rights pursuant to which, under certain conditions, the Company will register its shares of common stock issuable upon exercise of the
warrants held by the Lenders.
The
interest on the loan was calculated using the interest method with the debt issuance costs paid directly to the Lenders (financing fees) and the fair value of the warrants issued to
the Lenders treated as a discount on the debt. The debt issuance costs for legal fees are included in prepaid expenses and other current assets and in other assets in the accompanying balance sheet.
The amortization of the debt discount is recorded as a noncash interest expense and the amortization of the debt issuance costs is recorded as other income (expense) in the statements of operations.
In
March 2011, the Company recorded a loss of approximately $0.3 million on the early extinguishment of its previous debt, which consisted of the write-off of the
unamortized portions of the debt discount and the deferred issuance costs of approximately $0.2 million, the unaccrued portion of the final payment of $0.1 million and a prepayment
penalty of $50,000. This loss is recorded as an early extinguishment of debt in 2011 in the statements of operations.

Operating Leases
The Company leases a 36,960 square-foot building consisting of office and laboratory space in Palo Alto, California, for
its corporate headquarters. The lease term commenced in March 2008 and has scheduled annual rent increases through the lease expiration in March 2018. Rent expense is recognized on a
straight-line basis over the term of the lease. The Company is also responsible for certain operating expenses. The lease provided a $0.4 million allowance from the landlord for
tenant improvements. This amount has been included in deferred rent in the accompanying December 31, 2011 and 2010 balance sheets and is being amortized over the term of the lease, on a
straight-line basis, as a reduction to rent expense. Under the lease agreement, the Company provided a security deposit in the amount of $0.1 million in the form of a standing
letter of credit.
The
Company also continues to lease a 15,300 square-foot building consisting of office and laboratory space in Palo Alto, California. In October 2011, the Company amended the
lease to extend the lease term through December 31, 2013. In addition, the Company has two (2) one-year options to extend the lease through each of December 31, 2014
and 2015. The amendment provides for an allowance from the landlord of up to $50,000 for tenant improvements. As of December 31, 2011, the Company recorded prepaid rent of $33,000 related to
the
difference between the recorded rent expense and the cash payments related to this operating lease, plus the unamortized portion of the tenant improvement allowance. The lease is cancelable with four
months' notice. The Company currently

Guarantees and Indemnifications
The Company, as permitted under Delaware law and in accordance with its bylaws, indemnifies its officers and directors for certain
events or occurrences, subject to certain limits, while the officer or director is or was serving at the Company's request in such capacity. The term of the indemnification period is equal to the
officer's or director's lifetime.
The
maximum amount of potential future indemnification is unlimited; however, the Company currently holds director and officer liability insurance. This insurance limits the Company's
exposure and may enable it to recover a portion of any future amounts paid. The Company believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not
recognized any liabilities relating to these obligations for any period presented.
The
Company has certain agreements with contract research organizations with which it does business that contain indemnification provisions pursuant to which the Company typically agrees
to indemnify the party against certain types of third-party claims. The Company accrues for known indemnification issues when a loss is probable and can be reasonably estimated. The Company would also
accrue for estimated incurred but unidentified indemnification issues based on historical activity. There were no accruals for or expenses related to indemnification issues for any period presented.

GSK
In September 2011, the Company amended and expanded its research and development collaboration with GSK (the Master Amendment) to,
among other things, give effect to certain rights in GSK '052 that would be acquired by the U.S. government in connection with GSK's contract for government funding to support GSK's further
development of GSK '052, provide GSK the option to extend its rights around the bacterial enzyme target leucyl-tRNA synthetase (LeuRS), as well as to add new programs for tuberculosis (TB)
and malaria using the Company's boron chemistry platform. As a result of the Master Amendment, the Company received a $5.0 million upfront payment in September 2011 (the Amendment Fee) and may
receive additional milestone payments, bonus payments and research funding as described below, all of which, when earned, will be non-refundable and non-creditable. The Company
is also eligible to receive royalties on future sales of resulting products.
The
original research and development collaboration with GSK was entered into in October 2007 for the discovery, development and worldwide commercialization of boron-based systemic
anti-infectives against four discovery targets. The Master Amendment terminated three of the four target-based research projects under the original agreement. All rights to the compounds
developed under these three projects, except for compounds with a specified activity level against LeuRS, will revert to the Company. In addition, the Master Amendment terminated all previous
activities within the fourth target-based project under the original agreement, except GSK's activities related to GSK '052, which was licensed by GSK in July 2010 under the original agreement. GSK
retained sole responsibility for the further development and commercialization of GSK '052 and will continue to be obligated to make bonus payments to the Company, if certain development and
regulatory events occur and if certain sales levels for this drug are achieved, and to pay the Company royalties on annual net sales of GSK '052. Any future payment obligations of GSK with respect to
the three terminated projects or with respect to previous activities within the fourth project, other than those related to GSK '052, were also terminated. The Master Amendment also terminated any
research and development obligations that the Company had with respect to the original agreement.
The
Master Amendment added a new program for TB, under which GSK will fund the Company's TB research activities through to candidate selection, including paying the Company for the
services of its employees and for any third-party vendor costs it incurs in connection with the agreed TB research plan. Once TB compounds meet specified candidate selection criteria, GSK will have
the option to license such compounds and, upon exercise of this option, would become responsible for all further development and commercialization of such compounds. The Company would be eligible for
bonus payments, if certain development and regulatory events occur, if certain sales levels for a TB compound are achieved, and for royalties on sales of resulting products.
In
addition, the Master Amendment provided an option for GSK to expand its rights around LeuRS in return for a bonus payment, the amount of which will depend upon the timing of GSK's
exercise of this option. The Master Amendment also allowed GSK to initiate an additional collaborative research program directed toward LeuRS (New Research Program) and, provided such initiation
occurs before October 5, 2013, the term of the collaboration agreement would be extended for a minimum of two
years from the date of such initiation. The Company and GSK would conduct collaborative research under any such New Research Program to pursue additional drug candidates to candidate selection and any
such future work would be funded by GSK, including paying the Company for the services of its employees and for any third-party vendor costs it incurs in connection with an
106
Table of Contents

Notes to Financial Statements (Continued)

agreed
research plan for such a program. Upon candidate selection, GSK would make a milestone payment to the Company and would have the right to undertake further development and commercialization at
its sole expense, in which case the Company would become eligible for additional milestone payments, bonus payments and royalties on sales of resulting products.
At
its sole discretion, and without any penalty or liability, GSK may terminate the TB program, any New Research Program or the development or commercialization of any compounds that
result from such programs. If such termination occurs, rights to the compounds affected by the termination will revert to the Company, subject to certain restrictions on the further development of
certain of these compounds. If GSK terminates one of these programs entirely, the Company will have no further obligations with respect to research services under the canceled program and GSK will pay
the Company for all such research services performed by the Company prior to the date of termination.
The
Master Amendment also includes the option for GSK to acquire rights to certain compounds from the Company's malaria program, which the Company conducts through a collaboration with
MMV. GSK will have the option to license certain compounds from the program on an exclusive worldwide basis upon completion of a proof of concept clinical trial. Upon exercise of this option, GSK
would assume sole responsibility for the further development and commercialization of any such compounds, the Company would receive an option exercise payment from GSK and, pursuant to a related
September 2011 amendment to the Company's development agreement with MMV, the Company would be obligated to pay MMV one-third of the option exercise payment. The Company would also be
eligible for bonus payments from GSK, if certain regulatory events occur and if certain sales levels for a malaria compound are achieved, and for royalties on sales of resulting products. The amended
development agreement with MMV also obligates the Company to pay MMV one-third of any such bonus payments up to a maximum amount equal to the total amount paid by MMV to the Company
pursuant to the research and development agreements between these two parties. Development of the initial lead candidate under the MMV collaboration was discontinued in November 2011 and the Company
and MMV are in the process of evaluating other compounds of the Company to determine if there is another potential lead candidate for development.
In
2007, pursuant to the original agreement, GSK paid the Company a $12.0 million non-refundable, non-creditable upfront fee, which was being recognized
over the six-year research collaboration term on a straight-line basis in accordance with the revenue recognition guidance for multiple element arrangements. As of the
effective date of the Master Amendment, $4.2 million of the 2007 upfront fee was included in deferred
revenue. The Company evaluated the terms of the Master Amendment relative to the entire arrangement and determined the Master Amendment to be a material modification to the original agreement for
financial reporting purposes. As a result, the Company evaluated the entire arrangement under the guidance of ASU 2009-13, which it had adopted in January 2011, and identified all
undelivered elements under the agreement, as modified. Because the Master Amendment terminated all previously active programs under the original agreement except the GSK '052 program, for which GSK
had become solely responsible when it exercised its option to license GSK '052 in 2010, the Company determined that there were no undelivered elements remaining from the original agreement as of the
effective date of the Master Amendment. The Company also determined that the only undelivered element resulting from the Master Amendment, other than contingent deliverables, was the research services
it is obligated to provide under the new TB program. The Company then determined the best estimate selling price (BESP) for the TB program research services based on factors such as estimated direct
expenses and other costs involved in providing these
107
Table of Contents

Notes to Financial Statements (Continued)

services,
the contractually agreed reimbursement rates for the services and estimated margins the Company has realized under its other contracts involving the provision of and reimbursement for
research services. Based on these same factors, the Company also concluded that the contractually agreed reimbursement rates for the services approximate the fair value of such services. The Company
then allocated arrangement consideration equal to the BESP for the undelivered TB program research services and determined that the estimated consideration still to be received from GSK for these
services would be sufficient to ensure the BESP amount is available for future revenue recognition using the proportional performance method. This amount was then deducted from the sum of the
consideration currently committed to be received in the future under the Master Amendment plus any deferred revenue from the original agreement, with the remainder recognized as revenue on the
modification date. This process resulted in excess deferred revenue at the date of the material modification of $9.2 million, composed of the remaining deferred revenue balance from the 2007
upfront fee of $4.2 million and the $5.0 million Amendment Fee from the Master Amendment. This $9.2 million was recognized as revenue in September 2011, upon the material
modification of the original agreement. The Company determined that the amount of revenue recognized for the year ended December 31, 2011 would have been $2.8 million, if the GSK
agreement, as modified by the Master Amendment, were subject to the revenue recognition standards for multiple element arrangements that were in effect prior to January 1, 2011. As of
December 31, 2011, the Company has no remaining deferred revenue associated with the GSK agreement.

As
of December 31, 2011, GSK was no longer considered a related party. Previously, GSK was deemed a related party by ownership of more than 10% of the voting common stock of the
Company and its relationship with a former director of the Company that was also an executive officer of GSK. Accordingly, related party transactions were reported as contract
revenuerelated party in the statements of income and accounts receivablerelated party and accrued liabilitiesrelated party in the balance sheets.
The
Company has evaluated the remaining contingent payments under the agreement with GSK, as amended by the Master Agreement, based on the new authoritative guidance for research and
development milestones and determined that certain of these payments meet the definition of a milestone and that all such milestones are substantive milestones because they are related to events
(i) that can be achieved based in whole or in part on either the Company's performance or on the occurrence of a specific outcome resulting from the Company's performance, (ii) for which
there was substantive uncertainty at the date the agreement was entered into that the event would be achieved
108

Notes to Financial Statements (Continued)
8. License, Research, Development and Commercialization Agreements (Continued)
and
(iii) that would result in additional payments being due to the Company. Accordingly, revenue for these achievements will be recognized in its entirety in the period when the milestone is
achieved and collectibility is reasonably assured. Other contingent payments under the agreement, as amended by the Master Amendment, for which payment is contingent upon the results of GSK's
performance will not be accounted for using the milestone method. Such payments will be recognized as revenue when earned and collectibility is reasonably assured. For the year ended
December 31, 2011, the Company did not recognize any revenue from milestone payments or bonus payments under its agreement with GSK. GSK is further obligated to pay the Company royalties on
annual net sales of licensed products. To date, no products have been approved and therefore no royalty fees have been earned under this agreement.
Lilly
In August 2010, the Company entered into a research agreement with Lilly under which the companies will collaborate to discover
products for a variety of animal health applications. Lilly will be responsible for worldwide development and commercialization of compounds advancing from these efforts. The Company received an
upfront payment of $3.5 million in September 2010, which is being recognized over a four-year research term on a straight-line basis, and the Company will receive a
minimum of $6.0 million in research funding with the potential of up to $12.0 million in research funding, if successful. In addition, the Company received a $1.0 million
milestone fee in 2011 and will be eligible to receive additional payments upon the achievement of specified development and regulatory milestones. As of
December 31, 2011, the Company has deferred revenue of $2.3 million related to the upfront fee and $0.8 million related to the research funding.
In
addition, the Company will be eligible to receive tiered royalties on sales escalating from high single digit to in the tens royalties on sales, depending in part upon the mix of
products sold. Such royalties continue through the later of expiration of the Company's patent rights or six years from the first commercial sale on a product-by-product and
country-by-country basis
Unless
earlier terminated, the agreement continues in effect until the termination of royalty payment obligations. The agreement allows for termination by Lilly upon written notice, with
certain additional payments to the Company and a notice period that has a duration dependent on whether the notice is delivered prior to the first regulatory approval of a product under the agreement
or thereafter. In addition, either party may terminate for the other party's uncured material breach of the agreement. In the event of termination by the Company for material breach by Lilly or
termination upon written notice by Lilly, Lilly would assign to the Company certain trademarks and regulatory materials used in connection with the products under the agreement and grant to the
Company an exclusive license under Lilly's patent rights covering such products, and the Company would pay to Lilly a reasonable royalty on sales of such products should the Company desire an
exclusive license. In the event of termination for material breach by the Company, Lilly will be entitled to a return of all research funding payments for expenses the Company has not incurred or
irrevocably committed.

Medicis
In February 2011, the Company entered into a research and development agreement with Medicis Pharmaceutical Corporation (Medicis) to
discover and develop boron-based small molecule compounds directed against a target for the potential treatment of acne. The Company will be primarily responsible during a defined research
collaboration term for discovering and conducting early development of product candidates that utilize the Company's proprietary boron chemistry platform. The Company granted Medicis a
non-exclusive, non-royalty bearing license to utilize a relevant portion of the Company's intellectual property, solely and to the extent necessary, to enable Medicis to
perform additional development work under the agreement. Medicis will also have an option to obtain an exclusive license for products resulting from this collaboration. Upon exercise of this option,
Medicis will assume sole responsibility for further development and commercialization of the applicable product candidate on a worldwide basis.
Under
the terms of the agreement, the Company received a $7.0 million upfront payment from Medicis in February 2011. The Company has identified the deliverables within the
arrangement as a license on the technology and on-going research and development activities. The Company has concluded that the license is not a separate unit of accounting as it does not
have stand-alone value to Medicis. As a result, the Company will recognize revenue from the upfront payment on a straight-line basis over a six-year research term. As of
December 31, 2011, the Company has deferred revenue of $6.0 million related to this upfront fee.
The
Company will also be eligible to receive contingent payments if specified development and regulatory events occur. All such contingent payments, when earned, will be
non-refundable and non-creditable. The Company has evaluated the contingent payments under the agreement with Medicis based on the new authoritative guidance for research and
development milestones and determined that certain of these payments meet the definition of a milestone and that all such milestones are substantive milestones because they are related to events
(i) that can be achieved based in whole or in part on either the Company's performance or on the occurrence of a specific outcome resulting from the Company's performance, (ii) for which
there was substantive uncertainty at the date the agreement was entered into that the event would be achieved and (iii) that would result in additional payments being due to the Company.
Accordingly, revenue for these achievements will be recognized in its entirety in the period when the milestone is achieved and collectibility is reasonably assured. Other contingent payments under
the agreement for which payment is contingent upon the results of Medicis' performance will not be accounted for using the milestone method. Such payments will be recognized as revenue when earned and
collectibility is reasonably assured. For the year ended December 31, 2011,
110

the
Company did not recognize any revenue from milestones or other contingent payments under its agreement with Medicis.
In
addition, the Company will be eligible to receive tiered royalties on annual net sales of licensed product sold by Medicis or its sublicensees. To date, no products have been approved
and therefore no royalty fees have been earned under this agreement.

MMV
In March 2011, the Company entered into a three-year development agreement with MMV to collaborate on the development of
compounds for the treatment of malaria through human proof-of-concept studies. This development agreement was preceded by a 2010 research agreement between the two parties. In
August 2011, the Company and MMV amended the development agreement (Amendment 1) to expand, and increase the funding for, the Company's malaria compound development activities. In addition,
pursuant to Amendment 1, any 2011 advance payments in excess of the actual costs incurred by the Company for the research and development activities under the agreement are either refundable or
creditable against future payments at MMV's option. In September 2011, the Company and MMV further amended their research and development agreements (Amendment 2) to allow, among other things,
the Company to grant GSK an option to sublicense certain malaria compounds on an exclusive worldwide basis upon the completion of a proof of concept clinical trial. Upon exercise of this option, GSK
would assume sole responsibility for the further development and commercialization of the licensed compounds, the Company would receive an option exercise payment from GSK and the Company would be
obligated to pay MMV one-third of the option exercise payment. The Company would also be eligible for bonus payments from GSK, if certain regulatory events occur and if certain sales
levels for a malaria compound are achieved, and for royalties on sales of resulting products. Amendment 2 also obligates the Company to pay MMV one-third of any such bonus payments up to a
maximum amount equal to the total amount paid by MMV to the Company pursuant to the research and development agreements between these two parties. In November 2011, development of the initial lead
candidate under the MMV collaboration was discontinued and the Company and MMV are in the process of evaluating other compounds of the Company to determine if there is another potential lead candidate
for development.
Under
the terms of the March 2011 development agreement, the Company received a $1.7 million advance payment from MMV in March 2011 to fund malaria compound development activities
through December 2011. In February 2011, the Company had received an advance payment of $0.6 million to fund ongoing research activities through December 2011 in connection with an extension of
its previous research agreement with MMV. In October 2011, the Company received an additional $0.9 million in
111
Table of Contents

Notes to Financial Statements (Continued)
8. License, Research, Development and Commercialization Agreements (Continued)
advance
payments related to the development agreement under Amendment 1. In addition, MMV awarded the Company $0.6 million for 2012 research funding. As of December 31, 2011, the Company
had $0.9 million of unspent advances under the development agreement and the Company and MMV agreed to credit $0.6 million of the unspent advances against the $0.6 million of 2012
research funding. The Company recorded the remaining $0.3 million of unspent advances as an accrued liability as of December 31, 2011. Additional funding for 2013 will be determined on
an annual basis at the sole discretion of MMV. The Company will recognize revenue from the advance payments as the research and development activities are performed. As of December 31, 2011,
the Company has deferred revenue of $0.6 million related to the research agreement.

Schering
In November 2009, Schering merged with Merck. In May 2010, the Company entered into a mutual termination and release agreement with
Merck pursuant to which the 2007 exclusive license, development and commercialization agreement with Schering for the development and worldwide commercialization of tavaborole was terminated. Under
the May 2010 agreement, the Company regained the exclusive worldwide rights to tavaborole, Merck provided for the transfer to the Company of all material and information related to tavaborole, Merck
paid $5.8 million to the Company, and the parties released each other from any and all claims, liabilities or other types of obligations relating to the 2007 agreement. Merck did not retain any
rights to this compound. No amounts were recognized subsequent to 2010.

9. Convertible Preferred Stock
The Company previously recorded the convertible preferred stock at fair value on the dates of issuance, net of issuance costs. The Company had classified the convertible preferred stock
outside of stockholders' equity (deficit) because the shares contained redemption features that were not solely within its control. Upon closing of the IPO in November 2010, 10,909,478 outstanding
shares of convertible preferred stock were automatically converted into 11,120,725 shares of common stock, and the related carrying value of $87.5 million was reclassified to additional
paid-in capital. As of December 31, 2011 and 2010, no convertible preferred shares were authorized, issued or outstanding.
10. Preferred Stock Warrants Liability and Common Stock Warrants
In connection with its prior debt financings, the Company issued warrants to purchase convertible preferred stock (Warrants #1, #2 and #3). In 2010 and 2009, the preferred stock warrants
liability was adjusted to its fair value at the end of each reporting period using the Black-Scholes option-pricing model to determine such fair value. During 2010 (prior to the IPO) and in 2009, the
Company recorded other expense (income) for the changes in the fair value of the warrants of $(1.4) million and $0.1 million, respectively. In connection with the closing of the IPO in November
2010, all three of the preferred stock warrants automatically converted into common stock warrants and the preferred stock warrants liability, $0.4 million as of the conversion date, was
reclassified to additional paid-in capital. In connection with the 2011 debt financing, the Company issued additional common stock warrants to purchase common stock of the Company
(Warrants #4 and #5) (see Note 6).
As
of December 31, 2011, the following common stock warrants were issued and outstanding:

11. Stockholders' Equity
Shelf Registration
In December 2011, the Company filed a shelf registration statement on Form S-3 with the SEC (the Shelf
Registration). The Shelf Registration was declared effective by the SEC on January 5, 2012. The shelf registration statement permits the Company to sell, from time to time, up to $50,000,000 of
common stock, preferred stock, debt securities and warrants. In February 2012, the Company sold 3,250,000 shares of the Company's common stock in connection with this Shelf Registration (see
Note 16).
Initial Public Offering
In November 2010, the Company completed its IPO of common stock pursuant to a registration statement that was declared effective on
November 23, 2010. The Company sold 13,382,651 shares of
113

11. Stockholders' Equity (Continued)
its
common stock, which included 1,382,651 shares of the Company's common stock sold pursuant to an over-allotment option granted to the underwriters, at a price to the public of $5.00 per
share. As a result of the IPO, the Company raised a total of $66.9 million in gross proceeds, and approximately $61.0 million in net proceeds after deducting underwriting discounts and
commissions of $3.2 million and estimated offering expenses of $2.7 million. Costs directly associated with the Company's IPO were capitalized and recorded as deferred offering costs
prior to the closing of the IPO. These costs have been recorded as a reduction of the proceeds received to determine the amount to be recorded in additional paid-in capital. Upon the
closing of the IPO, 10,909,478 outstanding shares of the Company's convertible preferred stock automatically converted into 11,120,725 shares of its common stock.
Concurrent
with the closing of the IPO, the Company sold 2,000,000 shares of its common stock through a private placement offering at a price of $5.00 per share. Gross proceeds raised in
the private placement were $10.0 million with issuance costs of approximately $16,000.
Preferred Stock
In November 2010, the Company amended and restated its certificate of incorporation to authorize 10,000,000 shares of preferred stock
upon the completion of the IPO of its common stock. As of December 31, 2011 and 2010, there was no preferred stock outstanding.
Common Stock
In November 2010, the Company amended and restated its certificate of incorporation to increase the authorized common stock to
100,000,000 shares upon the completion of the IPO of its common stock.

2010 Equity Incentive Plan
In November 2010, the Company's board of directors approved the Company's 2010 Equity Incentive Plan (2010 Plan), which became
effective on the date of the IPO of the Company's common stock. A total of 929,832 shares of common stock were initially reserved for future issuance under the 2010 Plan; and shares subject to
outstanding stock awards granted under the Company's 2001 Equity Incentive Plan (2001 Plan) that expire or terminate for any reason prior to their exercise or settlement and would otherwise return to
the 2001 Plan reserve will be added to the shares reserved under the 2010 Plan. At the 2011 annual meeting of stockholders of the Company held on May 25, 2011, the
114
Table of Contents
Anacor Pharmaceuticals, Inc.
Notes to Financial Statements (Continued)
11. Stockholders' Equity (Continued)
stockholders
approved the Company's 2010 Plan, as amended, to among other things, increase the aggregate number of shares of common stock authorized for issuance under the plan by 1,200,000 shares. In
addition, the number of shares of common stock available for issuance under the 2010 Plan will automatically increase on January 1
st
of each year for ten years commencing
on January 1, 2012 by an amount equal to 4% of the total number of shares outstanding on December 31
st
of the preceding calendar year, or a lesser number of shares
of common stock as determined by the Company's board of directors. The maximum number of all shares that may be issued under the 2010 Plan as of December 31, 2011 is 4,075,922 shares. As of
December 31, 2011, the Company had 931,879 shares of common stock reserved for future issuance under the 2010 Plan.
The
2010 Plan provides for the grant of awards to employees, directors and consultants in the form of incentive stock options, nonstatutory stock options, stock appreciation rights,
restricted stock awards, restricted stock unit awards, performance awards and other awards. Incentive stock options may be granted to employees and nonstatutory options may be granted to employees,
directors or consultants at exercise prices of no less than 100% of the fair value of the common stock on the grant date as determined by the board of directors. Incentive stock options may only be
granted for ten years from the date the 2010 Plan was approved by the board of directors. Options typically vest as determined by the board of directors, at the rate of 25% at the end of the first
year with the remaining balance vesting monthly over the next three years, but may be granted with different vesting terms. Options granted under the 2010 Plan expire no later than ten years after the
date of grant. The stock issuable under the 2010 Plan may be shares of authorized but unissued or reacquired common stock of the Company, including shares repurchased by the Company on the open market
or otherwise.
2010 Employee Stock Purchase Plan
The Company's board of directors adopted the 2010 Employee Stock Purchase Plan (ESPP) in November 2010, and the Company's stockholders
approved the ESPP in November 2010. The ESPP became effective upon the IPO of the Company's common stock. A total of 250,000 shares of common stock were initially reserved for future issuance under
the ESPP and are pursuant to purchase rights granted to the Company's employees or to employees of any of the Company's designated affiliates. The number of shares of common stock reserved for
issuance under the ESPP will automatically increase on January 1
st
of each year for ten years commencing on January 1, 2012 by the least of (i) 1% of the
total number of shares outstanding on December 31
st
of the preceding calendar year, (ii) 80,000 shares or (iii) the number of shares of common stock as
determined by the Company's board of directors. The ESPP permits eligible employees to purchase common stock at a discount by contributing, normally through payroll deductions, up to 10% of their base
compensation during defined offering periods. The price at which the stock is purchased is equal to the lower of 85% of the fair market value of the common stock at the first date of an offering
period, or 85% of the fair value of the common stock on the date of purchase. In July 2011, the Company issued 44,897 shares of the Company's common stock related to the first purchase under the ESPP.
As of December 31, 2011, 205,103 shares remain available for future issuance under the ESPP.
2001 Equity Incentive Plan
In connection with the Company's IPO, no further options or stock purchase rights will be granted under the 2001 Plan. Any shares
remaining for issuance under the 2001 Plan as of the IPO date became available for issuance under the 2010 Plan. All outstanding stock awards granted under the
115
Table of Contents

Notes to Financial Statements (Continued)
11. Stockholders' Equity (Continued)
2001
Plan will remain subject to the terms of the 2001 Plan; however, shares that expire, terminate or are forfeited prior to exercise or settlement of such shares become available for issuance under
the 2010 Plan. As of December 31, 2011, there were 1,678,139 shares of common stock reserved for future issuance under the 2001 Plan.
Under
the 2001 Plan, the board of directors was authorized to grant options or stock purchase rights to employees, directors and consultants. Options granted were either incentive stock
options or nonstatutory stock options. Incentive stock options were granted to employees with exercise prices of no less than the fair value, and nonstatutory options were granted to employees or
consultants at exercise prices of no less than 85% of the fair value of the common stock on the grant date as determined by the board of directors. Options vest as determined by the board of
directors, generally at the rate of 25% at the end of the first year, with the remaining balance vesting monthly over the next three years. Options granted under the Plan expire no later than ten
years after the date of grant. The Plan provides for the new issuance of common stock of the Company upon the exercise of stock options. As of December 31, 2011 and 2010, there were no shares
subject to repurchase by the Company.
Stock Option Repricing
Effective April 1, 2009, the Company's board of directors approved the reduction of the exercise prices of certain outstanding
stock options previously granted to employees and nonemployees of the Company who were still providing services to the Company as of that date. The Company repriced options to purchase 664,371 shares
of the Company's common stock that included both vested and unvested stock options granted from June 2007 through August 2008 with original exercise prices ranging from $12.75 to $22.25 per share. The
Company's board of directors
adjusted all of the original exercise prices for the repriced options to $7.25 per share and determined the fair value of the underlying shares of common stock to be $5.00 per share on the date of the
repricing. No other terms of the repriced options were modified and these repriced stock options will continue to vest according to their original vesting schedules and will retain their original
expiration dates.
The
modification was treated as a one-for-one exchange of the previously issued stock options for new stock options with an exercise price of $7.25. The Company
recorded a one-time stock-based compensation charge of $0.2 million for the incremental value of the vested options. In addition, the Company will record additional stock-based
compensation charges of $0.5 million for the incremental value of the unvested repriced options, which will be recognized over the remaining vesting period of the new stock options. The 2009
share numbers for options granted and options canceled in the table below include the 664,371 option shares that were exchanged in connection with the April 2009 repricing.

Stock-Based Compensation
The Company estimates the fair value of stock options granted on the date of grant using the Black-Scholes option-pricing model, which
requires the use of highly subjective and complex assumptions to determine the fair value of stock-based awards. As a newly public company, sufficient relevant historical data does not exist to
support the volatility of the Company's common stock prices or the expected term of its stock options. Therefore, the Company has used the average historical volatilities of a peer group of
publicly-traded companies within its industry to determine a reasonable estimate of its expected volatility. In addition, the Company has opted to use the simplified method for estimating the expected
term of options granted to employees.
The
risk-free interest rate assumptions are based on U.S. Treasury Constant Maturities rates with durations similar to the expected term of the related awards. The expected
dividend yield assumption is based on the Company's historic and expected absence of dividend payouts.
For
options granted prior to January 1, 2006, the graded-vested (multiple-option) method continues to be used for expense attribution related to the portion of those options that
were unvested as of January 1, 2006. The straight-line (single-option) method is being used for expense attribution of all awards granted on or after January 1, 2006.
The
fair values for stock options granted (estimated at the date of grant) to employees and the Company's nonemployee directors and the fair value of employee stock purchase plan (ESPP)

Prior
to its IPO, the Company had historically granted stock options at exercise prices not less than the fair market value of its common stock as determined by the board of directors
based on input from
management. The determination of estimated fair value of its common stock on the date of grant had been based on a number of objective and subjective factors including: recent sales of convertible
preferred stock to investors; comparable rights and preferences of other outstanding equity securities; progress of research and development efforts and milestones attained; results of operations,
financial position and levels of debt and available capital resources of the Company; perspective provided by valuation analyses of the Company's stock performed by management; and the likelihood of a
liquidity event such as an IPO or the sale of the Company given prevailing market and biotechnology sector conditions.
Based
on the assumptions used in the Black-Scholes valuation model for ESPP, the weighted-average estimated fair value of employee stock purchase rights granted under the ESPP for the
year ended December 31, 2011 was $2.85.
Employee
stock-based compensation expense recognized in 2011, 2010 and 2009 was calculated based on awards ultimately expected to vest and has been reduced for estimated forfeitures.
Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
The
Company recorded stock-based compensation expense as follows (in thousands):

As
of December 31, 2011, the Company had $5.1 million and $0.2 million of total unrecognized compensation expense, net of estimated forfeitures, related to
outstanding stock options and ESPP stock purchase rights, respectively, that will be recognized over weighted-average periods of 2.6 years and 0.6 years, respectively.

11. Stockholders' Equity (Continued)
Stock Options Granted to Nonemployees
During 2011, 2010 and 2009, the Company granted nonemployees 51,400, 67,500 and 64,800 option shares, respectively, to purchase common
stock. Included in the 2009 grants to nonemployees were 49,800 option shares that were exchanged in connection with the April 2009 repricing. Stock-based compensation expense related to stock options
granted to nonemployees is recognized as the stock options vest. The stock-based compensation expense related to nonemployees will fluctuate as the fair value of the Company's common stock fluctuates.
The Company believes that the fair values of the stock options are more reliably measurable than the fair values of the services received. The fair value of nonemployee options in 2011, 2010 and 2009
was estimated using the Black-Scholes method with the following weighted-average assumptions: expected life is equal to the remaining contractual term of the award as of the measurement date;
risk-free rate is based on the U.S. Treasury Constant Maturity rate with a term similar to the expected life of the option at the measurement date; expected dividend yield of 0%; and an
average volatility ranging from 70% to 80%. The Company has used the average historical volatilities of a peer group of publicly-traded companies within its industry to estimate volatility.
12. 401(k) Plan
The Company sponsors a 401(k) Plan to which eligible employees may elect to contribute, on a pretax basis, subject to certain limitations. The Company does not match any employee
contributions.
13. Income Taxes
The income tax benefit for 2009 was a federal refundable credit of $15,000. The American Recovery and Reinvestment Act of 2009 allowed corporations without current tax liabilities to
obtain refunds for certain research tax credit and alternative minimum tax credit carryforwards by electing to forego the 50% additional first year depreciation for new property acquired after
June 30, 2008 and placed in service before January 1, 2010. This Act extended the provisions of the Housing Assistance Tax Act of 2008 (H.R. 3221) which was set to expire for assets
placed in service before January 1, 2009. For tax year 2009, the Company elected to a obtain refund for a portion of its research and development tax credit carryforwards from taxable years
before January 1, 2006.
A
reconciliation of the expected income tax benefit computed using the federal statutory income tax rate to the Company's effective income tax rate is as follows:

Due
to the Company's lack of earnings history, the deferred assets have been fully offset by a valuation allowance as of December 31, 2011 and 2010. The increase in the valuation
allowance on the deferred tax assets was $19.4 million, $5.1 million and $10.6 million for 2011, 2010 and 2009, respectively.
As
of December 31, 2011, the Company had net operating loss carryforwards for federal and state income tax purposes of approximately $142.1 million and
$142.2 million, respectively. These federal and state carryforwards will begin to expire in the years 2021 and 2013, respectively. Approximately $0.2 million of the net operating loss
carryforwards relates to stock option deductions, the benefit of which will be credited to additional paid in capital in the year such losses are utilized. The Company also had federal research and
development tax credit carryforwards of approximately $6.2 million, which expire beginning in 2024 if not utilized. In addition, state research and development tax credit carryforwards of
approximately $3.7 million will carry over indefinitely.
Internal
Revenue Code Section 382 places a limitation (the Section 382 Limitation) on the amount of taxable income, that can be offset by net operating loss carryforwards
after a change in control (generally, a greater than 50% change in ownership). Typically, after a control change, a company cannot deduct operating loss carryforwards in excess of the
Section 382 Limitation. Due to these changes in ownership provisions, utilization of the net operating loss and tax credit carryforwards may be subject to an annual limitation regarding their
utilization against taxable income in future periods. The Company has determined that a change in control, as defined by Internal Revenue Code Section 382, occurred in December 2010. However,
the computed Section 382 Limitation is not expected to prevent the Company from utilizing its net operating losses prior to their expiration if the Company can generate sufficient taxable
income to do so in the future.
The
Company adopted the provisions of the standard for accounting for uncertainties in income taxes on January 1, 2007. Upon adoption, the Company recognized no material
adjustment in the liability for unrecognized tax benefits. As of December 31, 2011 and 2010, the Company had approximately $2.0 million and $1.5 million, respectively, of
unrecognized tax benefits, none of which would currently affect the Company's effective tax rate if recognized due to the Company's deferred tax

If
applicable, the Company would classify interest and penalties related to uncertain tax positions in income tax expense. Through December 31, 2011, there has been no interest
expense or penalties related to unrecognized tax benefits. The tax years 2001 through 2010 remain open to examination by
one or more major taxing jurisdictions to which the Company is subject. There are no income tax examinations currently in progress.
14. U.S. Government Grant
In October 2010, the Company was awarded $1.5 million in grant funds by the United States Department of the Treasury under the Qualifying Therapeutic Discovery Project program to
support research for six projects with the potential to produce new therapies. The qualifying expenses under this program were incurred by the Company during 2010 and 2009. The Company recognized
$1.5 million as government grant revenue for the year ended December 31, 2010. As of December 31, 2010, $0.1 million was due to the Company and was included in government
grant receivable.

Common Stock Offering
On February 14, 2012, the Company issued and sold 3,250,000 shares of the Company's common stock related to an underwriting
agreement (the "Underwriting Agreement") with Canaccord Genuity Inc. (the "Underwriter") for the issuance and sale of up to 3,737,500 shares of the Company\'s common stock, including 487,500
shares issuable to the Underwriter pursuant to a 30-day over-allotment option. The price to the public in this offering was $6.60 per share, or gross proceeds of
$21.5 million, and the Underwriter purchased the shares from the Company pursuant to the Underwriting Agreement at a price of $6.25 per share. The net proceeds to the Company from this offering

ITEM 9A. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management, Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and
procedures as of December 31, 2011. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means
controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded,
processed, summarized and reported within the time periods specified in the SEC's rules and forms.
Disclosure
controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or
submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding
required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31,
2011 at the reasonable assurance level.
Management's Report on Internal Control Over Financial Reporting for the Year Ended December 31, 2011
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is
defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and
Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2011 based on the guidelines established in
Internal ControlIntegrated
Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
Our
internal control over financial reporting includes policies and procedures that provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. Based on the results of our evaluation, our management concluded that our
internal control over financial reporting was effective as of December 31, 2011. We reviewed the results of management's assessment with our Audit Committee. The Company's independent
registered public accountants, Ernst & Young LLP, audited the financial statements included in this Annual Report on Form 10-K and have issued an attestation report on the Company's
internal control over financial reporting. The report on the audit of internal control over financial reporting appears below.

Report of Independent Registered Public Accounting Firm
The
Board of Directors and Stockholders
Anacor Pharmaceuticals, Inc.
We
have audited Anacor Pharmaceuticals, Inc.'s internal control over financial reporting as of December 31, 2011, based on criteria established in
Internal ControlIntegrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission ("the COSO criteria").
Anacor Pharmaceuticals, Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control
over financial reporting included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal
control over financial reporting based on our audit.
We
conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A
company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and
(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the
financial statements.
Because
of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In
our opinion, Anacor Pharmaceuticals, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the
COSO criteria.
We
also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2011 financial statements of Anacor
Pharmaceuticals, Inc. and our report dated March 15, 2012 expressed an unqualified opinion thereon.
