Item 1. Business
Overview
We are a clinical-stage biopharmaceutical company
focused on the development of therapeutics for the treatment or prevention of addiction and related disorders. Our lead investigational
new drug product, AD04, is being developed as a therapeutic agent for the treatment of alcohol use disorder (“AUD”). In January
2021, we expanded our portfolio in the field of addiction with the acquisition of Purnovate, LLC via a merger into our wholly owned subsidiary,
Purnovate, Inc., (“Purnovate”) and we continue to explore opportunities to expand our portfolio in the field of addiction
and related disorders such as pain reduction, both through internal development and through acquisitions. Our vision is to create the
world’s leading addiction focused pharmaceutical company. Additionally, we are using Purnovate’s adenosine drug discovery
and development platform to invent and develop novel chemical entities as drug candidates for large unmet medical needs with the intention
of spinning off or licensing drug candidates and development programs not related to the field of addiction (see Purnovate and the Adenosine
Platform below).
Alcohol Use Disorder and AD04
AUD is characterized by an urge to consume
alcohol and an inability to control the levels of consumption. We have completed the clinical phase of the landmark
ONWARD™ pivotal Phase 3 clinical trial using AD04 for the potential treatment of AUD in subjects with certain
target genotypes. As of this filing, all 302 patients included in the trial had completed dosing and follow up visits and the final
monitoring and close-out activities are underway (a total of 303 patients were recruited and then randomized in the trial, however, one subject never initiated
treatment and has been excluded from enrollment numbers and will not be included in the full analysis data set or efficacy analysis for
the trial). ONWARD trial data is expected to be unblinded and analyzed in the second quarter
of 2022. We believe our approach is unique in that it targets the serotonin system and individualizes the treatment of AUD, through
the use of genetic screening (i.e., a companion diagnostic genetic biomarker). We have created an investigational companion
diagnostic biomarker test for the genetic screening of patients with certain biomarkers that, as reported in the American Journal
of Psychiatry (Johnson, et. al. 2011 & 2013), we believe will benefit from treatment with AD04. Our strategy is to integrate
the pre-treatment genetic screening into AD04’s label to create a patient-specific treatment in one integrated therapeutic
offering. Our goal is to develop a genetically targeted, effective and safe product candidate to treat AUD by reducing or
eliminating the patients’ consumption of alcohol.
We have a worldwide, exclusive license from the
University of Virginia Patent Foundation (d.b.a the Licensing & Venture Group) (“UVA LVG”), which is the licensing arm
of the University of Virginia, to commercialize our investigational drug candidate, AD04, subject to Food and Drug Administration (“FDA”)
approval of the product, based upon three separate patent application families, with patents issued in over 40 jurisdictions, including
three issued patents in the U.S. Our investigational agent has been used in several investigator-sponsored trials and we possess or have
rights to use toxicology, pharmacokinetic and other preclinical and clinical data that support our landmark ONWARD pivotal Phase 3 clinical
trial. Our therapeutic agent was the product candidate used in a University of Virginia investigator sponsored Phase 2b clinical trial
of 283 patients. In this Phase 2b clinical trial, ultra-low dose ondansetron, the active pharmaceutical agent in AD04, showed a statistically
significant difference between ondansetron and placebo for both the primary endpoint and secondary endpoint, which were reduction in severity
of drinking measured in drinks per drinking day (1.71 drinks/drinking day; p=0.0042), and reduction in frequency of drinking measured
in days of abstinence/no drinking (11.56%; p=0.0352), respectively. Additionally, and importantly, the Phase 2b results showed a significant
decrease in the percentage of heavy drinking days (11.08%; p=0.0445) with a “heavy drinking day” defined as a day with four
(4) or more alcoholic drinks for women or five (5) or more alcoholic drinks for men consumed in the same day.
The active pharmaceutical agent in AD04, our lead
investigational new drug product, is ondansetron, which is also the active ingredient in Zofran®, which was granted FDA
approval in 1991 for nausea and vomiting post-operatively and after chemotherapy or radiation treatment and is now commercially available
in generic form. In studies of Zofran®, conducted as part of its FDA review process, ondansetron was given acutely at dosages
up to almost 100 times the dosage expected to be formulated in AD04 with the highest doses of Zofran® given intravenously
(“i.v.”), which results in approximately 160% of the exposure level as oral dosing. Even at high doses given i.v. the studies
found that ondansetron is well-tolerated and results in few adverse side effects at the currently marketed doses, which reach more than
80 times the AD04 dose and are given i.v. The formulation dosage of ondansetron used in our drug candidate (and expected to be used by
us in our Phase 3 clinical trials) has the potential advantage that it contains a much lower concentration of ondansetron than the generic
formulation/dosage that has been used in prior clinical trials, is dosed orally, and is available with use of a companion diagnostic genetic
biomarker. Our development plan for AD04 is designed to demonstrate both the efficacy of AD04 in the genetically targeted population and
the safety of ondansetron when administered chronically at the AD04 dosage. However, to the best of our knowledge, no comprehensive clinical
study has been performed to date that has evaluated the safety profile of ondansetron at any dosage for long-term use as anticipated in
our ongoing and planned clinical trials.
According to the National Institute of Alcohol
Abuse and Alcoholism (the “NIAAA”) and the Journal of the American Medical Association (“JAMA”), in the United
States alone, approximately 35 million people each year have AUD (such number is based upon the 2012 data provided in Grant et. al. the
JAMA 2015 publication and has been adjusted to reflect a compound annual growth rate of 1.13%, which is the growth rate reported by U.S.
Census Bureau for the general adult population from 2012-2017), resulting in significant health, social and financial costs with excessive
alcohol use being the third leading cause of preventable death and is responsible for 31% of driving fatalities in the United States (NIAAA
Alcohol Facts & Statistics). AUD contributes to over 200 different diseases and 10% of children live with a person that has an alcohol
problem. According to the American Society of Clinical Oncologists, 5-6% of new cancers and cancer deaths globally are directly attributable
to alcohol. And, The Lancet published that alcohol is the leading cause of death in people ages 15-49 globally. The Centers for
Disease Control (the “CDC”) has reported that AUD costs the U.S. economy about $250 billion annually, with heavy drinking
accounting for greater than 75% of the social and health related costs. Despite this, according to the article in the JAMA 2015 publication,
only 7.7% of patients (i.e., approximately 2.7 million people) with AUD are estimated to have been treated in any way and only 3.6% by
a physician (i.e., approximately 1.3 million people). In addition, according to the JAMA 2017 publication, the problem in the United States
appears to be growing with almost a 50% increase in AUD prevalence between 2002 and 2013.
AUD is characterized by an urge to consume alcohol
and an inability to control the levels of consumption. Until the publication of the fifth revision of the Diagnostic and Statistical
Manual of Mental Disorders in 2013 (the “DSM-5”), AUD was broken into “alcohol dependence” and “alcohol
abuse”. More broadly, overdrinking due to the inability to moderate drinking is called alcohol addiction and is often called “alcoholism”,
sometimes pejoratively.
Since ondansetron is already manufactured for
generic sale, the active ingredient for AD04 is readily available from several manufacturers, and we have contracted with a U.S. manufacturer
to acquire ondansetron at a cost expected to be under $0.01 per dose. Clinical trial material (“CTM”) has already been manufactured
for the ONWARD Phase 3 trial. The CTM has demonstrated good stability after four years with the stability studies to date.
We have also developed the manufacturing process
at a third-party vendor to produce tablets at what we expect will serve for commercial scale production (i.e., greater than 1 million
tablets per batch), also at a cost expected to be less than $0.01 per dose. A proprietary packaging process has been developed, which
appears to extend the stability of the drug product. Packaging costs are expected to be less than $0.05 per dose. We do not have a written
commitment for supply of either the tablets or the packaging and believe that alternative suppliers are available to whom we can transfer
the processes that have been developed.
Methods for the companion diagnostic genetic test
have been developed as a blood test, and we established the test with a third-party vendor capable of supporting our clinical program.
Additionally, we have built validation and possible approval of the companion diagnostic into the Phase 3 program, including that we plan
to store blood samples for all patients in the event additional genetic testing is required by regulatory authorities.
COVID-19 Impact
Recruitment of patients in the ONWARD Phase 3
trial was slower than anticipated due to COVID-19 related governmental lockdowns in countries in which we were conducting the ONWARD Phase
3 trial. However, we have now completed the trial. Our corporate offices were open and operating without pause throughout the pandemic.

Disease Targets and Markets for AD04
Limitations of Current AUD Therapies
Today the most common treatments for AUD are directed
at achieving abstinence and typical treatments include psychological and social interventions. Most therapies actually require abstinence
prior to initiating therapy. Abstinence requires dramatic lifestyle changes often with serious work and social consequences. Frequently,
patients cannot attend family and social events in order to ensure compliance with abstinence, and patients often must suffer from the
stigma of having been labelled an alcoholic. Significant side effects of current pharmacologic therapies include mental side effects such
as psychiatric disorders and depressive symptoms and physical side effects such as nausea, dizziness, vomiting, abdominal pain, and hepatoxicity.
In fact, according to peer reviewed studies referenced in The Sober Truth: Debunking the Bad Science Behind 12-Step Programs and the
Rehab Industry, L. Dodes and Z. Dodes, 2014 by Dr. Lance Dodes, the former Director of the substance abuse treatment unit of Harvard’s
McLean Hospital, 90% or more of patients that use current therapy solutions, such as Alcoholics Anonymous, do not achieve long-term abstinence.
There are four drugs approved by the FDA and marketed
in the United States for the treatment of alcohol addiction, Antabuse® (disulfram) Vivitrol® (naltrexone),
Revia® (naltrexone) and Campral® (acomprosate) and one drug, Selincro® (nalmefene) is
marketed outside of the United States. All of the approved drugs, other than Selincro®, require abstinence prior to commencing
treatment with the drug, and all five drugs are known to have significant side effects.
Antabuse® was approved for the
treatment of alcohol dependence more than 50 years ago, making it the oldest such drug on the market. It works by interfering with the
body’s ability to process alcohol. Its method of action and purpose is to cause patients that drink alcohol while taking Antabuse® to experience numerous and extremely unpleasant adverse effects, including, among others, flushing, nausea, and palpitations,
with the goal that patients will continue the medication but refrain from drinking in order to avoid these effects.
Naltrexone, which can be taken as a once-daily
pill (Revia®) or in an approved once-monthly injectable form (Vivitrol® ) that requires a doctor to administer
is often associated with gastrointestinal complaints and has been reported to cause liver damage when given at certain high doses. As
a result, it carries an FDA boxed warning, a special emphasized warning, for this side effect.
Campral®, taken by mouth three
times daily, acts on chemical messenger systems in the brain.
Selincro® has not been approved
for sale in the United States.
Our Proposed Solution
Our goal with AD04 is to develop an effective
and safe product to treat AUD that does not require abstinence as part of the treatment and does not have the negative side effects of
the current drugs on the market. Our product candidate, AD04, is designed for genotype positive patients who desire to control their drinking
but cannot or do not want to completely abstain from drinking. By removing the difficulties associated with abstinence and the side effects
associated with the other current products on the market, we believe that we may be able to remove barriers to patient adoption that inhibit
adoption of current therapies and can attract a greater portion of the many millions of patients with AUD that remain untreated. Unlike
other therapies, our investigational product, AD04, uses a novel mode of action for treating AUD that involves genetic screening with
a companion diagnostic genetic test prior to treatment and is designed to reduce cravings for alcohol to effectively curb alcohol intake,
without the requirement of abstinence prior to or during treatment. Our product candidate is intended to be easy to use since it is administered
orally, currently on a twice daily basis and with a once-a-day tablet planned as part of the product’s life cycle management. To
date, clinical testing of AD04 has shown it to have a positive safety and tolerability profile with side effects similar to placebo.
The companion diagnostic genetic test to be used to identify patients
that are most likely to benefit from treatment with AD04 may potentially enhance the likelihood of a successful outcome for those undergoing
treatment. Additionally, it may provide doctors with the opportunity to have a non-threatening conversation about alcohol with their patients
and may provide the patient an acceptable path to help them determine if they might be a candidate for help with their alcohol use. If
the test results are positive, they would have a science-based rationale for their treatment, which reduces some of the stigma patients
might otherwise endure, and potentially allows them to be treated in the confidence of their doctor with an oral tablet.
Strengths and Competitive Advantages
Large Market Opportunity for an Effective
Solution
In the United States alone, approximately 35 million
people each year have AUD. Based on data from the Phase 2b trial of AD04 and our analysis of publicly available genetic databases, we
preliminarily estimate that about one in three patients with AUD in the U.S. will have the genetic markers to indicate possible treatment
with AD04. At this time, we are not aware of any oral pharmaceutical treatment approved in the U.S. that addresses the needs of patients
who desire to control their drinking but cannot or do not want to abstain from drinking. The current abstinence-based treatments have
limitations. The limited side effects expected for our investigational new drug, based on clinical data so far, are also believed to be
an important factor in the expected rapid uptake of AD04 in the market. Our approach, if approved by FDA, may allow for social drinking
to continue and is aimed at reducing the dangerous, heavy drinking. This would allow patients to live the life they want without the stigma
associated with complete abstention and currently endured by those seeking help for their excessive drinking. Assuming that one-third
of AUD patients are genotype positive for treatment with AD04 and a $255 price for a one month supply of the drug (assumed pricing based
on an average of prices published by Blue Cross Blue Shield in June 2017 for tier-3 oral, on-patent, chronic maintenance drugs, discounted
by 16.6%, to reflect the average difference between retail and wholesale pricing for branded drugs as reported by drugs.com), the total
potential market for AD04 would be approximately $36 billion in the United States alone.
Beyond the United States, alcohol consumption
worldwide is a serious health issue. The 2014 Global Status Report on Alcohol and Health published by the World Health Organization (the
“WHO”) states that 5.9% of all deaths (about 3.3 million per year) and 5.1% of disease worldwide are attributable to alcohol
consumption. Europe consumes over 25% of the total alcohol consumed worldwide despite only having 14.7% of the world’s population.
The WHO estimates that about 55 million people in Europe have AUD and, within Europe, Eastern Europe has a particularly acute problem
with Russia estimated to have about 21 million people with AUD. The WHO further estimates that 17.4% of adult Russians and 31% of adult
Russian males have AUD, and the Organization for Economic Cooperation and Development data indicates that 30% of all deaths in Russia
are alcohol related as reported by Quartz Media.
Companion Genetic Bio-Marker Aimed at Identifying
Patients Most Likely to Respond To Treatment, Potentially Results in Increased Use of AD04
We believe our drug is unique in that it is designed
to reduce heavy drinking in individuals with certain genotypes. We are pursuing a strategy that aims to integrate pre-treatment screening
with the companion diagnostic genetic test into the drug label, essentially combining the test and treatment into one integrated therapeutic
offering that has combined intellectual property protections. This companion diagnostic testing approach may be a useful genetic screening
tool to predict those most likely to respond to the drug and to have minimal side effects. Based on the clinical experience to date and
publicly available databases, we believe the genetic prevalence of genotype positive people is about 33% of the population in the United
States. We previously believed the prevalence in Scandinavia and in certain areas of Central and Eastern Europe may be greater than 50%,
but our experience in the ONWARD Phase 3 clinical trial indicates the prevalence in this area to also be about 33%. The FDA has agreed
that the Phase 3 trials of AD04 can proceed only enrolling patients that are genotype positive, which greatly reduces the cost, time and
risk relative to a trial that also enrolled patients that are genotype negative for treatment with AD04. We are conducting our current
landmark ONWARD pivotal Phase 3 clinical trial in counties in Scandinavia and Central and Eastern Europe, including Finland, Sweden, Latvia,
Poland, Bulgaria, and Croatia. We expect to use the ONWARD trial as a pivotal Phase 3 trial to serve as a basis for approval in both the
United States and Europe.
We believe that the companion diagnostic genetic
test enables physicians to more easily have an initial conversation with their patients about alcohol use and, for the patient, provides
a less threatening and obtrusive first step toward treatment because the conversation will include the topic of genetic testing and not
be solely about behavior. Patients that then test positive against the AD04 genetic panel would be expected to be more likely to then
receive a prescription for AD04 (based on an external quantitative market study of 156 primary care physicians and psychiatrists that
was conducted by Ipsos-Insight LLC, who we commissioned, and that concluded a majority of genetically targeted patients currently receiving
pharmacologic treatment would be switched to a drug with the characteristics expected for AD04).
Prior Work of Universities and our Ability
to Leverage Relationships Creates Cost Efficiencies
We have a worldwide, exclusive license to intellectual
property developed at the University of Virginia by our Chief Medical Officer, Dr. Bankole A. Johnson, who was Chairman of the Department
of Psychiatry & Neurobehavioral Sciences at the University of Virginia (and prior to that the Chief of the Division of Alcohol and
Drug Addiction at the University of Texas) and was Chair, Department of Psychiatry and Director of the Brain Science Research Consortium
Unit at the University of Maryland. Dr. Johnson has spent almost three decades researching the underlying subject matter. Significant
portions of the supporting research were also funded under grants from the National Institute of Health to the University of Virginia
and the University of Texas. On July 5, 2019, we entered into a Master Services Agreement and statement of work with Psychological Education
Publishing Company (“PEPCO”), a company owned by Dr. Johnson, that is engaged in the business of administering a behavioral
therapy program, Brief Behavioral Compliance Enhancement Treatment, for our Phase 3 clinical trial using AD04, for the treatment of AUD.
By leveraging the prior work of universities and
their researchers, including their pre-clinical studies and accumulated data, we believe we have developed a significant drug development
opportunity. Because of the licensing approach taken to secure intellectual property, including, without limitation, patents and rights
to clinical trial data, and our collaborations with the University of Virginia, we, historically have not had to incur the significant
costs that would normally be required to develop therapeutic treatments to the point of being ready to commence a Phase 3 clinical trial,
which often amount to tens of millions of dollars or more. In fact, based upon current information, and depending on what the regulatory
authorities may require to secure marketing authorization, we estimate that we will require approximately $10.7 million for the current
Phase 3 clinical trial (not including company overhead) and an additional $30 million or more of additional capital to complete our second
Phase 3 program (which includes $20 million for a confirmatory Phase 3 trial and any necessary Phase 1 clinical trials and other development
expenses and does not include the additional cost of a possible third Phase 3 clinical trial) as currently contemplated in order to achieve
regulatory approval for the use of AD04 to treat AUD in the United States and Europe. We have already used approximately $8.9 million
in funds derived from our initial public offering and subsequent financings and warrant exercises to fund trial activities. We anticipate
that the approximate $2.1 million needed to complete the initial Phase 3 clinical trial to the point of releasing data and the completion
of follow-up activities will be fully funded from our cash on hand. We anticipate, with our expected rate of expenditure, including Purnovate
related research and development projects and Company overhead, to have exhausted our funds on hand by the end of April 2023. Additional
funding will be needed to fund an additional Phase 3 trial of AD04, if necessary, as well as Purnovate research and development projects
and Company overhead. There is no assurance that such funds could be raised in time to complete the trial on acceptable terms.
The NIAAA has provided and continues to provide
technical assistance and advice to us, and we have applied for an NIAAA Research Resource Award, which if granted would provide financial
support for our Phase 3 clinical trial. Although there can be no assurance that we will be selected by the NIAAA to receive funding, since
we are not aware of any pharmaceutical company planning Phase 3 pivotal trials to serve as a basis for marketing approval for products
for the treatment of AUD, we believe AD04 would be a competitive candidate. Currently, much of the funding expected for grants such as
those for which we have applied has been diverted to COVID-19-related grants, and we are not certain if and when funding for grants such
as ours will be available.
Known, Well-Tested Agent Has Shown Favorable Results in Non-AUD
Uses
Ondansetron, the principal active pharmaceutical
agent in AD04 has been approved by the FDA to treat nausea and vomiting but is administered at much higher doses than we intend to use
and has shown limited side effects even at the higher dosages currently on the market. However, it has not been approved in our anticipated
dosage or for our anticipated uses and treatment period. Consequently, we expect to submit a new drug application, pursuant to section
505(b)(2) of the Federal Food, Drug, and Cosmetic Act, for U.S. marketing authorization. Section 505(b)(2) of the Federal Food, Drug,
and Cosmetic Act allows the FDA to rely, for approval of an NDA, on data not developed by the applicant. Such an NDA contains full reports
of investigations of safety and effectiveness, but where at least some of the information required for approval comes from studies not
conducted by or for the applicant and for which the applicant has not obtained a right of reference. Such applications permit approval
of applications other than those for duplicate products and permits reliance for such approvals on literature or an FDA finding of safety
and/or effectiveness for an approved drug product. A Phase 2b University of Virginia investigator sponsored clinical trial of AD04 for
the treatment of AUD showed promising results and no overt safety concerns (there were no statistically significant serious adverse events
reported). Not only did the trial show no statistically significant, serious adverse side effects, but both of the pre-specified endpoints,
reduction in severity of drinking measured in drinks per day of drinking day and reduction in frequency of drinking measured in days of
abstinence, were met with statistical significance as shown in the graph below:
Phase 2b Clinical Trial Results– Analysis
of Primary and Secondary Efficacy Endpoints for Target Genotypes
A 12-week, randomized, two-center, parallel-group,
double-blind, placebo-controlled, two-arm (four cell) clinical trial of oral ondansetron (n=283) conducted by University of Virginia
Our Substantial Proprietary Estate and Protection from Competition
We currently hold a worldwide, exclusive license
to three (3) patent families that provide us with the ability to exclude potential competitors from practicing the claimed inventions,
such as the use of ondansetron to treat any of the four (4) specified genotypes for AUD. Our licensed patent estate is expected to provide
us patent protection through 2032 plus possible extensions. Ondansetron, the active ingredient in AD04, has never been approved in a low
dosage near the AD04 dose of 0.33mg per tablet, and we believe our licensed patents will protect AD04 from any competitor that attempts
to bring to market an ondansetron dose at or near the AD04 dose for treatment of patients having one or more of the four target genotypes.
We believe use of the currently marketed doses
“off-label” will not be significant due to (i) the lack of demonstrated efficacy at currently marketed doses, (ii) potential
safety concerns if the currently marketed doses are used chronically as is expected to be necessary for treating AUD, and (iii) cutting
the smallest currently marketed dose into the 12 pieces that would be necessary to achieve the AD04 dose is deemed by us to be impractical
and likely to result in inaccurate dosing.
Companion Genetic Bio-Marker Aimed at Identifying
Patients Most Likely to Respond To Treatment, Potentially Results in Increased Use of AD04
We believe our drug is unique in that it is
designed to treat individuals with certain genotypes. We are pursuing a strategy that aims to integrate pre-treatment screening with
the companion diagnostic genetic test into the drug label, essentially combining the test and treatment into one integrated
therapeutic offering that has combined intellectual property protections. This companion diagnostic testing approach may be a useful
genetic screening tool to predict those most likely to respond to the drug and to have minimal side effects. Based on the clinical
experience to date and publicly available databases, we believe the genetic prevalence of genotype positive people is about 33% of
the population in the United. We previously believed the prevalence in Scandinavia and in certain areas of Central and Eastern
Europe may be greater than 50%, but our experience in the ONWARD Phase 3 clinical trial indicates the prevalence in this area to
also be about 33%. The FDA has agreed that the Phase 3 trials of AD04 can proceed only enrolling patients that are genotype
positive, which greatly reduces, the cost, time and risk relative to a trial that also enrolled patients that are genotype negative
for treatment with AD04. The FDA has indicated that any approval based on a trial only in genotype positive patients would result in
labeling restricted to treating genotype positive patients.
We believe that the companion diagnostic genetic
test enables physicians to more easily have an initial conversation with their patients about alcohol use and, for the patient, provides
a less threatening and obtrusive first step toward treatment because the conversation will include the topic of genetic testing and not
be solely about behavior. Patients that then test positive against the AD04 genetic panel would be expected to be more likely to then
receive a prescription for AD04.
Experienced Leadership
Our management, advisors and board of directors
have extensive experience in pharmaceutical development, the clinical trial and regulatory approval processes, drug commercialization,
financing capital-intensive projects, and developing new markets for pharmaceutical agents. Members of our team have previously worked
in senior management and senior officer positions, or led significant research initiatives at Gensia, Clinical Data, Shire, Viagene, New
River Pharmaceuticals, Collateral Therapeutics, Indivior, Krystal Biotech, Sucampo Pharmaceuticals, Osiris Therapeutics, Adenosine Therapeutics,
and the University of Virginia and University of Maryland in a broad range of therapeutic areas. Our management and board members have
particular expertise in the science and development of addiction related drugs and bringing new drugs to the market.
Our Strategy for AD04 and Addiction Related
Diseases and Disorders
We develop pharmaceutical treatments for addictions
and addictive disorders and related diseases and disorders. Our business strategy is to advance AD04, our lead investigational drug candidate,
toward regulatory approval for alcohol addiction in the United States, the European Union, and then eventually other territories. We subsequently
plan to develop label expansions into other indications (e.g., opioid use disorder, other drug addictions, obesity, smoking cessation,
eating disorders and anxiety). Additionally, we are inventing and developing novel therapeutic agents at our chemistry facilities and
seeking to acquire addiction related assets, particularly those expected to be synergistic with AD04 once it is marketed, if it is approved.
Our goals in executing this strategy are to keep
capital requirements to a minimum, expedite product development, gain access to clinical research and manufacturing expertise that will
advance product development, approval and eventual market uptake of our product, and rely on a well-defined and carefully executed intellectual
property strategy in order to position our products with long-term, defensible, competitive advantages. Execution of this strategy may
include seeking grant funding and funding from partners and collaborators when available on terms we believe to be favorable to us, and
on which there is no guarantee will be available. In collaboration with our CRO, we have been and are working to adapt the implementation
of our strategy in response to the ongoing coronavirus pandemic.
Our near-term strategy includes:
|
● |
Obtaining regulatory approval for our lead product in the United States and Europe. We have completed our initial Phase 3 clinical trial for the treatment of AUD in Scandinavia and Central and Eastern Europe and are conducting close-out activities to allow data analysis and reporting of results. If our initial Phase 3 clinical trial is successful, we expect to conduct a second, and possibly a third, Phase 3 clinical trial in the same areas but with additional clinical sites in the United States and Western Europe. |
|
● |
Prosecuting and expanding our intellectual property and product portfolio. We have acquired rights to a promising drug candidate and made a significant investment in the development of our licensed patent portfolio to protect our technologies and programs, and we intend to continue to do so. We have obtained exclusive rights to three different patent families directed to therapeutic methods related to our AD04 platform. These families include 3 issued U.S. patents, and at least one foreign equivalent patent covering AD04 issued in over 40 national jurisdictions, including most of Europe and Eurasia. Divisional and continuation applications to expand the coverage have also been filed in certain jurisdictions. Additionally, commencing in early 2021, we have an adenosine platform that has and is expected to continue to generate what we believe are patentable new chemical entities. We intend that further product portfolio expansions will be focused on promising addiction therapies and/or late-stage clinical assets. |
|
|
|
|
● |
Evaluating the additional use of our product candidate in other indications. In addition to alcohol addiction, we plan to conduct exploratory work to investigate using AD04 as a potential treatment for opioid use disorder, gambling addiction, smoking cessation, obesity, and other addiction related disorders in which 5-HT3 antagonism may have a treatment effect. We believe we will be able to undertake this initial exploratory effort with minimal additional cash cost to our company through the use of academic partnerships, grants, human laboratory studies and/or non-clinical studies. We believe that, due to its hypothesized mechanism of action (i.e., the modulation of the serotonin system in patients that are genetically targeted based on the apparent sensitivity to such modulation, where the modulation appears to reduce cravings), AD04 has the potential to be used for the treatment of such other addictive disorders. To date, we have not discussed these potential uses with the FDA or any other regulatory bodies. |
|
● |
Maximizing commercial opportunity for our technology.
AD04 targets large markets with significant unmet medical need. We intend to develop an extended release, once-a-day formulation of AD04
to enhance compliance and market appeal
|
|
● |
Managing our business with efficiency and discipline.

The clinical development plan for AD04 can be
described as a two-stage development strategy in which we expend limited resources to achieve the significant value inflection point of
Phase 3 data in our primary indication of AUD. With a successful trial and the risk reduction associated with that success, we would then
be ready to conduct the final trials to seek approval in the U.S. and Europe as shown below:
AD04 — Two-Stage Clinical Development Strategy — Conduct
the Phase 3 clinical trials sequentially
* |
Even if the 1st Phase 3 trial is not accepted by the FDA as a pivotal trial due to the study not being well-powered for the FDA’s currently stated end point, we still expect that the EMA will require only one additional trial. In this case, however, a 3rd trial might be required by the FDA (i.e., three Phase 3 trials in total). If two additional trials are required for FDA approval after an initial Phase 3 trial conducted in the EMA, we would expect to run the 2nd and 3rd trials in parallel (i.e., at the same time) so as not to increase the expected time to approval. The 2nd Phase 3 trial is expected to require $20 million in direct expenses, and up to $10 million in additional other development expenses is expected to be required. A possible 3rd Phase 3 trial would be expected to require an additional $20 million in clinical trial related expenditures. |
Assuming approval of AD04, we plan to execute a two-stage commercialization
plan. With psychiatrists and addiction specialists treating a majority of the current AUD patients today and with psychiatrists most likely
to be familiar with the mechanism of action of AD04, we believe that a relatively small psychiatry-targeted, specialty sales force could
successfully sell AD04 into the market. This plan creates the opportunity for us to develop into a commercial enterprise with an initial
niche-market sales force at a relatively low cost for market entry. It also expands the universe of potential acquirers of our company
or AD04 to smaller and mid-size pharmaceutical companies. Once success is shown in the niche market and the thought leaders and early
adopters are prescribing AD04, market adoption risk will have been greatly reduced and we would expect to be able to sell or partner with
a large pharmaceutical partner to develop AD04 as a blockbuster product. This commercialization plan is shown below:

Ondansetron History and Foundation for Treating
AUD
Ondansetron is a 5-HT3 receptor antagonist. Preclinical
and pharmacobehavioral studies suggest that blockade of serotonin-3 receptors will influence the dopamine reward system activated by alcohol,
decreasing dopamine release and attenuating craving for alcohol (Dawes, MA et al., 2005b; Johnson, BA et al., 2002; Lovinger, DM, 1999a).
Early clinical studies found that the efficacy of ondansetron is limited to certain subgroups of the alcohol-dependent population and
suggested the differential effect could be predicted based on age of onset of alcoholism, an indistinct concept likely confounded by genetic,
regional and ethnic differences (Johnson, BA et al., 2000; Kranzler, HR et al., 2003). Recent research suggests the variable effect may
be predictable based on molecular mechanism of ondansetron action and individual subject genotype of key genes in the serotonin system
(Enoch, MA et al., 2010; Johnson, BA et al., 2011; Kenna, GA et al., 2009).
We are pursuing development of ondansetron in
the alcohol-dependent population. Clinical studies will initially focus on the use of a low dose, oral tablet (0.33 mg administered twice
daily) to reduce alcohol consumption in subjects with genotypes that have been correlated with a responsive to treatment with ondansetron.
Ondansetron was first approved by the FDA in 1991
as a solution for injection. Subsequent approvals were obtained for oral tablets in dosage forms and an oral solution. It is marketed
as Zofran® and is also available in generic formulations, and it has been used widely for the approved indications –
prevention of nausea and vomiting associated with certain cancer chemotherapies and radiotherapies and for the prevention of postoperative
nausea or vomiting — at adult doses of 8–24 mg/day with manageable side effects.
Ondansetron has been administered to dogs‚
rats‚ and mice as part of a preclinical toxicology program which included single-dose acute‚ repeated-dose studies. Ondansetron
was not mutagenic in the standard battery of microbial tests for mutagenicity and no carcinogenic effects were seen in 2-year studies
in rats and mice with oral ondansetron doses up to 10 and 30 mg/kg/day, respectively. In studies of rats and rabbits there was no evidence
of reproductive toxicity seen on fertility, early embryonic development, perinatal/postnatal development or fetal development of the F2
generation. Based on these studies, as well as over 20 years of human use in clinical trials and the post-marketing environment, ondansetron
is considered to be a well-tolerated drug with a generally mild safety profile.
Ondansetron, by blocking the 5-HT3 receptor, is
known to affect dopaminergic signaling in the brain; and the scientific rational for use of a 5-HT3 antagonist in the treatment of alcohol
dependence is well established (Johnson, BA, 2004). Briefly, studies suggest that: the rewarding effects of alcohol involve activation
of the 5-HT3 receptors leading to release of dopamine within the mesolimbic system of the brain (McBride, WJ et al., 2004). Thus, by blocking
activation of the 5-HT3 receptor, ondansetron may reduce the ethanol-stimulated release of dopamine leading to reduced feelings of pleasure
or reward and consequently, reduced consumption (Carboni, E et al., 1989; Costall, B et al., 1987; Hagan, RM et al., 1990; Imperato, A
and Angelucci, L, 1989; Lovinger, DM, 1999b; McBride, WJ et al., 2004; Minabe, Y et al., 1991; Rasmussen, K et al., 1991; Wozniak, KM
et al., 1990; Yoshimoto, K et al., 1996).
Preclinical studies have demonstrated that alcohol
stimulates the release of both serotonin (5-hydroxytryptamine or 5-HT) and dopamine within the cortio-mesolimbic system (Campbell, AD
et al., 1996; Campbell, AD and McBride, WJ, 1995; Di Chiara, G and Imperato, A, 1988; Imperato, A and Angelucci, L, 1989; Yoshimoto, K
et al., 1992; Yoshimoto, K et al., 1996; Zazpe, A et al., 1994). Other studies have shown that alcohol potentiates the effects of 5-HT
at the 5-HT3 receptor, leading to augmented release of dopamine, and that ondansetron and the selective antagonists of the 5-HT3 receptor
inhibit dopaminergic firing and release of dopamine in response to alcohol and serotonin (Costall, B et al., 1987; Lovinger, DM, 1991;
Minabe, Y et al., 1991; Rasmussen, K et al., 1991; Yoshimoto, K et al., 1996; Zazpe, A et al., 1994; Zhou, Q et al., 1998). Finally, numerous
in vivo studies in rats and mice have shown that ondansetron and other selective antagonist of the 5-HT3 receptor reduce volitional intake
of alcohol in models selectively bred for alcohol preference (Fadda, F et al., 1991; Hodge, CW et al., 1993; McBride, WJ and Li, TK, 1998;
Meert, TF, 1993; Tomkins, DM et al., 1995).
The aforementioned nonclinical studies have shown
that 5-HT3 and dopamine interactions in the cortico-mesolimbic system appear to mediate many of the reinforcing effects of alcohol. Collectively
the available nonclinical studies suggest that, by inhibiting the 5-HT3 receptor and reducing the release of dopamine in the cortico-mesolimbic
area, ondansetron can interfere with the dopamine reward system activated by alcohol and lead to reduced alcohol intake (Barnes, NM and
Sharp, T, 1999; Dawes, MA et al., 2005b; Johnson, BA et al., 1993; Johnson, BA and Cowen, PJ, 1993; Lovinger, DM, 1991,
1999a; Swift, RM et al., 1996; Tomkins, DM et al., 1995).
Five clinical studies have been conducted that
demonstrate ondansetron is a promising treatment for alcohol-dependent individuals (Johnson, BA et al., 2011; Johnson, BA et
al., 2000; Kenna, GA et al., 2009; Kranzler, HR et al., 2003; Sellers, EM et al., 1994). Several important findings
in these studies guide the design of future clinical studies, including:
|
(1) |
Ondansetron’s efficacy in alcohol-dependent individuals is associated optimally with a small dose of the compound (0.25-0.33 mg twice daily), a dose that is <1/10 of the dose used for adults for the currently approved indications. |
|
(2) |
In clinical studies in over 600 subjects, ondansetron was well-tolerated and safe, with a mild side-effect profile when administered to currently drinking alcohol-dependent individuals. Overall, the types of adverse events reported during multi-week clinical studies in alcohol dependence appear similar to those outlined in the package insert for the approved indications and to those reported in the literature for treatment in chronic liver disease, chronic fatigue syndrome and schizophrenia. |
|
(3) |
The extent of benefit with ondansetron treatment varies among different subtypes of alcohol-dependent subjects. Prior studies found that ondansetron benefited subjects with early-onset alcoholism (EOA) but not late-onset alcoholism (LOA). The pharmacological reason for this was not known, but it was presumed that the differential effect was due to a higher degree of serotonergic dysfunction in EOA (Johnson, BA et al., 2000; Kranzler, HR et al., 2003). |

the development of AD04 and which is described more fully in the following section titled “Phase 2b Investigator Initiated Clinical
Trial of AD04 for Alcohol Use Disorder Conducted by the University of Virginia.”
A Dose-Ranging, Placebo-Controlled, 6-Week
Study of Ondansetron in Alcoholic-Dependent Subjects
In 1994, Sellers et al. reported on the
effects of administration of 0.25 mg bid ondansetron (N=23), 2 mg bid ondansetron (N=25), or placebo (N=23) for 6 weeks in alcohol-dependent
males (Sellers, EM et al., 1994). Endpoints included change in drinks per drinking day (“DDD”) and proportion of responders,
where a responder was defined as a subject with a Reliable Change score > 1.96, representing an improvement of at least 2 standard
deviations. The Reliable Change score was calculated as the difference between pre- and post-test DDD divided by the standard error. Analyses
were conducted comparing pre-treatment with the Week 6 visit, representing the end-of-study medication administration, and pre-treatment
with the Week 7 visit, after completion of a 1-week follow-up period.
In the 71 subjects who completed the study, the
on-treatment changes in DDD were approximately -1.9 (0.25 mg bid), -1.2 (2 mg bid), and -1.3 (placebo), with neither ondansetron effect
being statistically different from the placebo effect. The corresponding changes from pre-treatment to Week 7 (after 6 weeks of treatment
and a 1-week follow-up) were approximately -2.7 (0.25 mg bid), -1.1 (2 mg bid), and -1.6 (placebo), with the difference between low-dose
ondansetron and placebo approaching statistical significance (p=0.06). By Week 6, nearly twice as many subjects on low-dose ondansetron
compared with those on either high-dose ondansetron or placebo showed significant improvement according to the Reliable Change score.
Lower baseline drinking and higher level of education were significant predictors of reduction in drinking while on treatment.
A Dose-Ranging, Placebo-Controlled, 11-Week
Study of Ondansetron in Alcoholic-Dependent Subjects
In 2000, Johnson et al. reported on the
co-administration of weekly cognitive behavioral therapy and either placebo or ondansetron at doses of 1, 4, and 16 µg/kg bid for
11 weeks (after a 1-week, single-blind, placebo lead-in) in 321 alcohol-dependent subjects (Johnson, BA et al., 2000). Endpoints
included drinks per day, DDD, percentage of days abstinent (“PDA”), total days abstinent, and plasma carbohydrate deficient
transferrin (CDT) level, an objective measure of drinking. Analyses were conducted comparing each dose group with placebo, with drinking
response variables analyzed as means of data collected from Weeks 3 through 12.
The table below sets forth treatment results.
Ondansetron treatment at doses of 1, 4, and 16 µg/kg bid resulted in statistically significant reductions in DDD and drinks per
day compared with placebo for EOA (age of onset ≤25 years). The maximum clinical effect was observed at the middle dose (4 µg/kg
bid), though the differences between doses were not statistically significant. At 4 µg/kg bid (but not at 1 or 16 µg/kg bid),
significant improvements in days and PDA were also achieved. LOA (age of onset ≥26 years) did not benefit from ondansetron treatment
at any dose studied.

The findings in this study support the earlier
evidence that the dose-response effect of ondansetron in reduction of alcohol consumption is not linear. Of the doses used in this study,
only 4 µg/kg (0.28 mg for a 70 kg person) bid exhibited clinically and statistically meaningful improvements in all efficacy endpoints.
This study also suggested that ondansetron may be an appropriate therapy for EOA, but not LOA.
An Open-Label, 8-Week Study Comparing Ondansetron
Effect in Early-Onset and Late-Onset Alcoholic Subjects
In 2003, Kranzler et al. reported on the
co-administration of weekly cognitive behavioral therapy and ondansetron at 4 µg/kg bid for 8 weeks to 40 alcohol-dependent subjects
(Kranzler, HR et al., 2003). The subjects were evenly divided between early-onset alcoholism (EOA; age of onset of the disorder
<25 years) and late-onset alcoholism (LOA; age of onset of the disorder ≥25 years). Endpoints included drinks per day, DDD, PDA,
Drinker Inventory of Consequences (DrInC) score, and percentage of heavy-drinking days, where heavy drinking was defined as ≥5 drinks
in a day for a male subject or ≥4 drinks in a day for a female subject. Analyses were conducted comparing pre-treatment with 8-week
values within onset category (EOA or LOA) and comparing treatment effects between categories.
The table below sets forth treatment results.
All efficacy parameters improved significantly on treatment in both groups. EOA subjects reported significantly greater improvements in
drinks per day, DDD, and DrInC score than LOA subjects. These findings, as noted earlier by Johnson et al., suggest that ondansetron
shows promise for treatment of EOA by improving drinking outcomes.

A 3-Period Study of Ondansetron Effect and
Sertraline Effect in Subgroups of Alcoholics Constructed Based on Genotypes of the Serotonin Transporter Gene
Constructed Based on Genotypes of the Serotonin
Transporter Gene
In 2009, Kenna et al. reported on a placebo-controlled
cross-over study in which 21 alcohol-dependent subjects received 0.5 mg/day ondansetron or 200 mg/day sertraline for 3 weeks, placebo
for 3 weeks and the alternative active medication for 3 weeks (Kenna, GA et al., 2009). An alcohol self-administration experiment
was conducted at the end of each treatment period. The primary endpoint was DDD during the final week of each treatment period.
During the first 3-week treatment period, ondansetron-treated
subjects carrying L/L genotype (n = 3), compared to the L/S and S/S carriers (n = 4), had a significantly fewer DDD (3.66 vs. 8.40, p
= 0.02). Within L/S and S/S group, there was no significant effect of ondansetron. A pronounced order effect confounded analyses after
the third 3-week treatment period.
Our clinical development program is designed to
demonstrate the safety and efficacy of ondansetron in the alcohol-dependent population in low dosages for long periods of time, while
targeting genotypes that have been shown to benefit from ondansetron treatment. Ultimately, this development program aims to establish
a scientific link between the biology of alcohol addiction and the therapeutic mechanism of ondansetron action, permitting genetically-based
prediction of ondansetron effectiveness.
Phase 2b Investigator Initiated Clinical Trial of AD04 for Alcohol
Use Disorder Conducted by the University of Virginia
In various studies, it has been shown that alcohol
dependent individuals with the LL genotype of the 5’-HTT and the TT genotype in the 3’-UTR LL and TT genotype have lower B-CIT
neuronal binding to 5-HTT. It is hypothesized that individuals with the LL or TT genotype, 5-HTT gene expression is suppressed by increased
alcohol consumption, and therefore, ondansetron, which causes 5-HTT gene expression would have the greatest effect upon individuals that
possess both the LL genotype of the 5’-HTT and the TT genotype in the 3’-UTR. A subsequent Phase 2b study (N = 283), conducted
by the University of Virginia for which we have acquired rights to the data, showed that a prospectively identified subgroup of alcohol-dependent
individuals with these specific polymorphisms of the serotonin transporter protein responded therapeutically to ondansetron administration
(Johnson, BA et al., 2011). Further analysis of this same data set against 18 additional polymorphisms located on the genes for the A
and B subunits of the serotonin 5-HT3 receptor revealed polymorphisms that were also associated with a therapeutic response to ondansetron.
Collectively, the genotypes from the two aforementioned analyses comprise the genotypes selected for testing in Phase 3 trials for AD04.
The current ONWARD Phase 3 study is testing ondansetron’s efficacy compared with placebo based on its ability to decrease the frequency
and amount of heavy drinking among alcohol dependent individuals with the selected genotypes.
Phase 2b Clinical Trial Study Design
The Phase 2b clinical trial conducted by the University
of Virginia was a 283-patient, 12-week, randomized, two-center, parallel-group, placebo-controlled study. Following a 1 week placebo run
in (single-blind), alcohol-dependent subjects were randomized to receive either 4 µg/kg ondansetron or placebo, orally, twice daily
(double-blind) for 11 additional weeks. In addition to study treatment, all subjects received weekly, standardized, manual-driven, cognitive
behavioral therapy.
Eligible subjects were classified to one of twelve
groups described by the 2×2 x 3 factorial combinations and randomized to placebo or ondansetron (4 mcg/kg twice daily [b.i.d.])
using a computed blocks randomization procedure that balances the twelve treatment groups on drinks/day ≤ 7.99 vs ≥8.00), age of
onset (early vs. late), and genotype (LL, SS, SL).
Genotyping and analysis of the study subjects
for the SNP rs1042173 (TT, TG or GG) in the 3´-UTR of the 5-SLC6A4 gene that codes for the serotonin transporter was performed following
randomization but prior to database lock. Genotyping and analysis of the study subjects for SNPs located on genes that govern expression
of the 5-HT3A and 5-HT3B subunits of the 5-HT3 receptor was performed after database lock.
During treatment, subjects were evaluated weekly
at the study center for efficacy, safety, and tolerability. Alcohol consumption was collected via the self-reported Timeline Follow-Back
(TLFB) method (Sobell and Sobell, Psychosocial & Biochem. Meth., 1992).
Efficacy measures were based on self-reported
drinking outcomes with drinks per drinking day (“DDD”), with a standard drink equal to 14 grams of alcohol, and the percentage
of days abstinent (“PDA”) being the pre-specified efficacy end points. Withdrawal symptoms, social functioning, and motivation
to use alcohol were assessed using standard questionnaires and scales. Subject safety was monitored through periodic electrocardiograms
(EKGs), physical exams, safety laboratories and collection of adverse events, concomitant medications, and vital signs. Additionally,
a post hoc analysis was conducted using the endpoint of percentage of heavy drinking days (“PDHD”), which is the number
of days of heavy drinking days in a month as a percentage of days in the month, because it is widely recognized as a clinically meaningful
endpoint and is expected to be an end point in a pivotal/Phase 3 trials. The PDHD end point requires that each day be determined to be
a heavy drinking day (e.g., a day in which a female drinks 4 or more drinks or a male drinks 5 or more drinks) or not, making each day
binary and requiring an increased sample size to ensure statistical power. Therefore, the goal of the PDHD analysis was to determine if
the was a trend toward and effect with PDHD without necessary achieving statistical significance.
The study objectives were to evaluate the safety
of AD04 and to test the hypotheses that: (i) ondansetron will have a greater effect of reducing the severity of alcohol drinking and of
increasing the percentage of days abstinent among alcohol-dependent subjects with the LL genotype as compared with S carriers (SS or SL)
of the 5´-HTTLPR; and (ii) ondansetron’s therapeutic effect will be greatest among alcohol-dependent subjects who possess
both the LL genotype of the 5´-HTTLPR and the TT genotype of rs1042173 in the 3´-UTR of the 5´-HTT. After completion
of the study, a planned additional analysis of the correlation between genotype and drinking outcomes was conducted considering 18 SNPs
located on the 5-HT3A and 5-HT3B subunit genes that were selected based on their minor allele frequency (≥ 0.05) in different ethnic
populations, to obtain uniform physical coverage of the two genes, and on results from previous genetic association studies. This latter
analysis identified three SNPs as having an apparent beneficial effect.
The primary analytic procedure used mixed-effects
linear regression models and a sensitivity analysis using repeated measures models.
Additionally, based on the expectation that subjects
with the LL and LL/TT variants of the SLC6A4 gene would respond to ondansetron treatment while others do not, the possibility that SNPs
in the 5-HT3A and 5-HT3B subunits of the 5-HT3AB receptor complex may also influence the response to ondansetron was planned as a post
hoc analysis. The possible role of SNPs on the HTR3A and HTR3B genes in the response to ondansetron is logical since the 5-HT3A receptor
subunit is the primary target for ondansetron’s actions, and the 5-HT3B receptor subunit may be associated with the availability
and externalization of the 5-HT3AB receptor complex. Thus, alterations in post-synaptic receptors, such as the 5-HT3AB receptor complex,
could have a large impact on signal transduction along post-synaptic neurons. For these analyses, a total of 18 SNPs on the genes for
the 5-HT3A and 5-HT3B subunits were examined. SNPs were selected based on their minor allele frequency (≥ 0.05) in different ethnic
populations, to obtain uniform physical coverage of the two genes, and on results from previous genetic association studies.
Summary Results — Safety:
Overall, 95% of the subjects in the ondansetron
group and 96% in the placebo group reported a treatment-emergent AE (TEAE) during the study. TEAEs occurred most frequently in the SOCs
of gastrointestinal disorders (ondansetron 65%, placebo 61%), metabolism and nutritional disorders (38%, 43%), and nervous system disorders
(60%, 58%). The incidence of TEAEs by preferred term was similar between the ondansetron and placebo groups. TEAEs that occurred at a
frequency ≥ 5% in the ondansetron group compared with the placebo group included constipation (32%, 21%), fatigue (39%, 25%), and dizziness
(21%, 12%). There was one death during the study; Subject #218 committed suicide on Study Day 40. The event was considered not related
to study drug. Treatment-emergent SAEs were reported in 3 (2.1%) ondansetron-treated subjects and 6 (3.8%) placebo-treated subjects. No
SAE was considered related to study drug, and detoxification was the only SAE that was reported for more than 1 subject (2 ondansetron
subjects). No clinically meaningful changes in clinical laboratory results, vital sign measurements, ECGs or physical examinations were
observed for subjects during the course of the study.
Summary Results Phase 2b Clinical Trial — Primary Analysis
of Efficacy of LL and LL/TT
Analysis of the LL genotype of the 5´-HTTLPR
as compared to the non-LL genotypes showed a significant reduction in DDD and PDA (Johnson, et.al, Am. Jrnl. Psych., 2011). However, the
demonstrated effect of the LL/TT vs. other patients was more pronounced, and carriers of LL/TT genotype who received ondansetron showed
a greater reduction in drinking compared to LL/TT on placebo. Carriers of the LL/TT genotype who received ondansetron showed a greater
reduction in DDD compared to: 1) LL/TT carriers who received placebo (difference of 2.05 drinks/drinking day; 95% CI, -3.72 to -0.39;
p=0.0158), 2) LL/Gx carriers who received ondansetron (difference of 2.29 drinks/drinking day; 95% CI, -3.99 to -0.72; p=0.0048), and
3) all other genotypes who received ondansetron treatment (difference of 2.58 drinks/drinking day; 95% CI, -3.94 to 1.22; p<0.0001);
and a greater PDA compared with: 1) the LL/TT genotype group treated with placebo (mean difference=12.38%; 95% CI= -1.57 to 26.33;
p= 0.0819), 2) LL/Gx carriers treated with ondansetron (mean difference=15.14%; 95% CI= 1.41 to 28.87; p= 0.0307), and 3) all other
genotypes treated with ondansetron (difference= 16.82%; 95% CI= 6.15 to 27.48; p=0.0020). The post hoc analysis of the PDHD endpoint
show that ondansetron treatment of subjects with the LL/TT genotype was associated with a larger (but not statistically significant) reduction
in PDHD compared to changes in PDHD in subjects with all other genotypes who received treatment with ondansetron (mean difference= -8.49%;
95% CI= 20.34 to 3.367; p= 0.1601). Similar trends (i.e., augmented reductions in PDHD) were observed for the LL/TT group treated with
ondansetron versus the LL/Gx genotype group treated with ondansetron and versus the LL/TT group treated with placebo (mean difference=-2.54%
95% CI= 17.74 to 12.66, p=0.7431; and mean difference= 5.72% 95% CI= 21.20 to 9.75, p=0.4684; respectively).
Identification of Modulators of the 5-HT3 Receptor
and Selection of the Phase 3 Genetic Panel for AD04
As stated above, a total of 18 SNPs on the genes
for the 5-HT3A and 5-HT3B subunits were examined with SNPs selected based on frequency and on results from previous genetic association
studies.
These analyses identified 3 SNPs (three in the
gene for the 5-HT3A subunit and one in the gene for the 5-HT3B subunit) that were significantly associated with a positive response to
ondansetron based on reductions in DDD and PDA. Thus, the genotype profile targeted for Phase 3 development is defined as those subjects
who carry the LL/TT genotype and/or one of three 5-HT3 SNPs of interest (i.e., rs1150226-AG and rs1176713-GG in the gene that encodes
the 5-HT3A receptor subunit and rs17614942-AC in the gene that encodes the 5-HT3B receptor subunit). The hypothesis that subjects who
are carriers of the genotype panel targeted for study in Phase 3 (“P3-genotype”, with such patients “genotype positive”
or “marker positive”) preferentially respond to treatment with ondansetron compared to subjects who do not carry any of the
genotypes targeted for study in Phase 3 were assessed using the drinking endpoints of DDD, PDA, and PDHD.
Carriers of the P3-genotype who received ondansetron
showed a greater reduction in DDD compared to P3-genotype carriers who received placebo (difference of 1.71 drinks/drinking day; 95% CI=
-2.88 to -0.54; p=0.0042), and compared to subjects treated with ondansetron who were not carriers of the P3-genotype (All Other-OND;
difference of 2.05 drinks/drinking day; 95% CI= -3.11 to -1.00, p=0.0001). In contrast, no difference was observed between non-P3-genotypes
who received ondansetron (All Other-OND) versus non-P3-genotypes who received placebo (All Other-Placebo; difference of 0.40 drinks/drinking
day; 95% CI= -0.43 to 1.23; p=0.3445). The mean baseline DDD for all subjects was 9.5 drinks/drinking day. Carriers of the P3-genotype
who received ondansetron (P3-OND) had a greater increase in PDA compared to P3-genotype carriers who received placebo (P3-Placebo; difference
of 11.56%; 95% CI= 0.80 to 22.31; p=0.0352) and compared to non-P3-genotype carriers who received ondansetron (All Other-OND; difference
of 11.52%; 95% CI= 1.76 to 21.28; p=0.0208). In contrast, no differences were observed for the PDA endpoint between non-P3-genotypes treated
with ondansetron versus non P3-genotypes treated with placebo (All Other-OND versus All Other-Placebo; difference of -0.96%; 95% CI= -8.61
to 6.69; p=0.8055). The mean baseline PDA for all subjects was 17%.
The results are summarized in the below graphs.
Phase 2b Clinical Trial Results — Analysis of Primary and
Secondary Efficacy Endpoints for Target Genotypes
A 12-week, randomized, two-center, parallel-group,
double-blind, placebo-controlled, two-arm (four cell) clinical trial of oral ondansetron (n=283)
As stated, above, the study was not powered to
achieve statistical significance against the binary-by-day end point of PDHD, however, carriers of the P3-genotype who received ondansetron
(P3-OND) showed a significantly greater reduction in PDHD compared to P3-genotype carriers who received placebo (P3-Placebo; difference
of -11.08%; 95% CI= -21.90 to 0.27; p=0.0445), and compared to non-P3-genotype carriers who received ondansetron (All Other-OND; difference
of -10.35%; 95% CI= -20.11 to -0.58; p=0.0378). In contrast, no difference was observed between non-P3-genotypes who received ondansetron
(All Other-OND) versus non-P3-genotypes who received Placebo (All Other-Placebo; difference of 2.88%; 95% CI= -4.80 to 10.56; p=0.4625).
The mean baseline PDHD for all subjects was 70%.
The results are summarized in the below graphs.
Phase 2b Clinical Trial Results — Post
Hoc Analysis of Effect on Percentage of Heavy Drinking Days (defined as 4/5 or more drinks in a day for a woman/man, respectively)
A 12-week, randomized, two-center, parallel-group,
double-blind, placebo-controlled, two-arm (four cell) clinical trial of oral ondansetron (n=283)
Definition of Heavy Drinking Day
As stated above, for the PDHD post hoc
analysis of the Phase 2b clinical trial data, a heavy drinking day was defined as a day when a female drank 4 or more drinks in a day,
with a drink being defined as containing 14 grams of alcohol, or when a man drank 5 or more drinks in a day, which was the definition
the FDA indicated to us was required. It is also currently the definition of “high-risk drinking” in Dietary Guidelines for
Americans 2015-2020 (U.S. Departments of HHS and Agriculture), the NIAAA’s definition of “binge drinking”, and has historically
been the definition for a heavy drinking day (Neal, D., & Carey, K., 2007). The Substance Abuse and Mental Health Services Administration
(SAMHSA) defines heavy drinking “as drinking 5 or more alcoholic drinks on the same occasion.” Subsequent to our analysis
of the Phase 2b data and agreement with the FDA on the definition of a heavy drinking day as 4/5 or more drinks in a day for females/males,
the FDA published a draft guidance, in which it states, “Those drinking 4 plus/5 plus [drinks for females and males, respectively]
even on occasion have significantly higher risks (10 to 20 percent) of meeting criteria for AUD.” The FDA’s draft guidance
then states that the NIAAA defines a heavy drinking day as more than 3 drinks in a day for a woman and more than 4 drinks in a day for
a man, which is currently only part of the NIAAA’s definition for “low-risk drinking”, and which is very similar but
not necessarily identical to what the FDA indicated to us was required and the criteria we used when generating our study report on the
Phase 2b. So, it is unclear which definition of a heavy drinking day the FDA will accept at this time. However, under this different definition
of a heavy drinking day as more than 3/4 for females/males, the Phase 2b trial data support the effect of AD04 on reducing heavy drinking
and showed a greater reduction in PDHD compared to P3-genotype carriers who received placebo (P3-Placebo; difference of -10.24%; 95% CI=
-21.18 to 0.70; p=0.0665), and compared to non-P3-genotype carriers who received ondansetron (All Other-OND; difference of -11.65%; 95%
CI= -21.54 to -1.77; p=0.0209). In contrast, no difference was observed between non-P3-genotypes who received ondansetron (All Other-OND)
versus non-P3-genotypes who received Placebo (All Other-Placebo; difference of 4.09%; 95% CI= -3.70 to 11.88; p=0.3033). We do not expect
a small change to the definition of a heavy drinking day to dramatically change our plans or probability of success. We intend to discuss
the definition of a heavy drinking day with the FDA and EMA prior to our relevant submissions.
Ongoing ONWARD Phase 3 Clinical Program
The FDA indicated we could proceed with a
randomized, placebo-controlled Phase 3 clinical trial design for the testing of AD04 as a treatment for AUD in patients that are
genotype positive when tested against the AD04 genetic panel using our companion diagnostic test (i.e., a negative genetic test
result will be an exclusion criterion). The initial Phase 3 trial, designated the ONWARD trial, started in February 2020 in
Scandinavia and Central and Eastern Europe. As of the date of this filing, all 302 patients included in the trial had completed
dosing and follow ups and the final monitoring and close-out activities are underway (a total of 303 patients were recruited and then randomized in the trial, however, one subject never initiated
treatment and has been excluded from enrollment numbers and will not be included in the full analysis data set or efficacy analysis for
the trial). The ONWARD trial was conducted in 25 clinical
sites across the six countries of Sweden, Finland, Poland, Latvia, Bulgaria and Croatia. Trial results are expected to be reported
in the second quarter of 2022.
The primary analysis will be the reduction from
baseline of heavy drinking as the primary endpoint, and reduction from baseline in total alcohol consumed will be the first secondary
endpoint using a gated analysis so that it will only be evaluated as secondary endpoint if the primary endpoint is successful. The definition
of a heavy drinking day will be greater than 40 grams or 60 grams of ethyl alcohol in a day for a woman or a man, respectively. An alternative
analysis is expected to be conducted for filing in the United States using the FDA specified endpoint of reduction in percentage of patients
with heavy drinking during the efficacy observation period as compared to placebo (FDA Feb. 2015 Draft Guidance Alcoholism: Developing
Drugs for Treatment Guidance for Industry ) and which the FDA has indicated will be acceptable. Under this guidance, the FDA appears
to now define a heavy drinking as more than three drinks in a day for a woman and more than four drinks in a day for a man, which is a
reduction from the prior definition. We intend to seek clarification from the FDA on the definition of a heavy drinking day prior to our
submission to them and do not believe a minor change to the definition of a heavy drinking day will be material to our plans.
If the ONWARD trial is successful, we intend to
consult with the FDA and EMA, and assuming agreement from the agencies, conduct a second Phase 3 clinical trial in a broader geography
that includes the United States. The trial design is expected to be the same as ONWARD trial but is expected to include 580 patients in
order provide increased exposure data to demonstrate the safety and tolerability of AD04 and increase the statistical power of the study.
Depending on the results of the ONWARD trial, which is be fully powered for the FDA endpoint, it is also possible that the FDA may require
a third Phase 3 trial. If a third Phase 3 trial is required, we would expect to conduct it in parallel with the second Phase 3 trial with
a goal of not delaying approval of AD04.
We have had a joint meeting with the Center for
Drug Evaluation and Review (“CDER”) and the Center for Devices and Radiological Health (“CDRH”), the two divisions
of the FDA responsible for drug approvals and device authorizations, respectively. At the meeting the divisions agreed that clinical validation
of our companion diagnostic test for AD04 will be evaluated by CDER and the technical validation of our companion diagnostic will be evaluated
by CDRH. We expect to need approval of a premarket approval application (“PMA”) or a premarket notification submission (“510(k)”)
from CDRH for the companion diagnostics to be used with the drug product. We already developed the methods for the companion diagnostic
as a blood test and established the test with a third-party vendor capable of supporting a Phase 3 clinical trial, and have built validation
and possible approval of the companion diagnostic into the Phase 3 program, including that we plan to store blood samples for all patients
in the event additional genetic testing is required by regulatory authorities.
We plan to test AD04 in adolescent patients (ages
12-17) as part of our next Phase 3 trial. If successful, we intend to request labeling for treating adolescent patients.
In parallel with the second Phase 3 trial, we
expect to conduct any standard Phase 1 studies required by the regulatory agencies. Studies that have been discussed with the FDA as potentially
being required might assess food effects, potentiation of the central nervous system effects of alcohol, and pharmacodynamic impact of
certain cytochrome P450 enzyme variants. We also expect to conduct a 12-month open-label Phase 1 safety study in at least 100 subjects
to evaluate the 12-month safety of AD04.

Additionally, the UVA LVG License grants rights
to data and know-how developed by the University of Virginia related to AD04, including, without limitation, to the data from the Phase
2b study described above.
As consideration for the rights granted in the
license agreement, we are obligated to pay UVA LVG yearly license fees and milestone payments, and a royalty based on net sales of products
covered by the patent-related rights set forth above. More specifically, upon commencement of the license we issued to UVA LVG Class A
Units (which was equal to four percent (4%) of our equity on the date of issuance) as a license issue. We are obligated to pay UVA LVG
(i) annual minimum royalties of $40,000 commencing in 2017; (ii)a $20,000 milestone payments that as originally due upon dosing the first
patient under a Phase 3 human clinical trial of a licensed product but has been paid in full, $155,000 upon the earlier of the completion
of a Phase 3 trial of a licensed product or the partnering of the licensed or sale of our company, $275,000 upon acceptance of an NDA
by the FDA, and $1,000,000 upon approval for sale of AD04 in the U.S., Europe or Japan; and (iii) royalties equal to a 2% and 1% of net
sales of licensed products in countries in which a valid patent exists or does not exist, respectively, with royalties paid quarterly.
In the event of a sublicense to a third party, we are obligated to pay royalties to UVA LVG equal to a percentage of what we would have
been required to pay to UVA LVG had we sold the products under sublicense ourselves. In addition, we are required to pay to UVA LVG 15%
of any sublicensing income. The license agreement, as amended on December 14, 2017 and further amended on December 18, 2019 and December
31, 2019 sets forth specific milestones completion deadlines including using commercially reasonable efforts to submit an NDA by December
31, 2024 and commence commercialization of an FDA approved product by December 31, 2025. The license agreement may be terminated by UVA
LVG upon sixty (60) days written notice if we breach our obligations thereunder, including failing to make any milestone, or failing to
use commercially reasonable efforts to submit an NDA or commence commercialization within the date specified above, failing to make other
required payments, or the failure to exercise diligence to bring licensed products to market. In the event of a termination, we will be
obligated to pay all amounts that accrued prior to such termination. The license agreement also contains other customary clauses and terms
as are common in similar agreements between industry and academia, including agreements to indemnify UVA LVG for any liabilities arising
out of or related to the licensee’s exercise of its rights under the license agreement, making the license grant subject to the
Bayh-Dole Act (35 U.S.C. 200 et seq.), the reservation of the licensor of the right to use the licensed intellectual property rights for
its internal, non-commercial purposes, limitations/disclaimers of various warranties and representations, reporting and record-keeping
requirements, and licensee liability insurance requirements.
The term of the license continues until the expiration,
abandonment or invalidation of the licensed patents, and following any such expiration, abandonment or invalidation will continue in perpetuity
on a royalty-free, fully paid basis.
The UVA LVG currently has a policy under which
up to 35% of the payments made to the UVA LVG under a license may be distributed to inventor of the licensed technology, therefor our
Chief Medical Officer in his capacity as inventor of the patents licensed by us from the UVA LVG may be eligible to receive such payments
from the UVA LVG.
PEPCO MSA
On July 5, 2019, we entered into a Master Services
Agreement (the “MSA”) and attached statement of work (the “SOW”) with Psychological Education Publishing Company
(“PEPCO”) to administer a behavioral therapy program during our upcoming Phase 3 clinical trial using AD04, for the treatment
of alcohol use disorder. Specifically, PEPCO is engaged in the business of training and certifying clinical investigators in the administration
of Brief Behavioral Compliance Enhancement Treatment (“BBCET”). PEPCO is owned by Dr. Bankole Johnson, our Chief Medical Officer.
We may terminate the MSA at any time upon ten (10) days prior written notice to PEPCO. Unless otherwise indicated in our notice of termination,
Work (as defined in the MSA) under any statement of work in progress at the time of the delivery of notice of termination shall continue
as if the applicable statement of work had not been terminated, and the terms hereof shall continue to apply to such work. We may also
terminate the MSA for cause due to PEPCO’s failure to perform its obligations thereunder upon three (3) days prior written notice
to PEPCO; provided, however, the Company may terminate the MSA immediately in the event of PEPCO’s violation, or threatened violation,
of certain provisions contained therein.
The statement of work under the MSA will terminate
upon the completion the final study report for the Trial and delivery of the final report by PEPCO on the supervision and monitoring of
the BBCET, including, without limitation, data reports. Notwithstanding the forgoing, the statement of work may be terminated by us upon
written notice to PEPCO.
It was anticipated that the compensation to be
paid to PEPCO for services under the MSA will be approximately $300,000, of which subject to approval of the Nasdaq Capital Market shares
of our common stock having a value equal to twenty percent (20%) of the fees due thereunder (the “Company Shares”) would have
been issued to Dr. Johnson as a consultant under the 2017 Equity Incentive Plan.
On December 12, 2019, we entered into an Amendment
(the “Amendment”) to the SOW. We had paid PEPCO $39,064 under the SOW for services rendered to date, leaving as estimated
balance of $274,779 estimated to be paid under the SOW. The Amendment provided us with a 20% discount on the remaining services to be
provided under the SOW and fixed the price of any remaining services under the SOW to be a total of $219,823 for all services required
for the use of Brief Behavioral Compliance Enhancement Treatment (BBCET) in support of Phase 3 clinical trial provided that payment be
made no later than December 13, 2019, which payment was made. As of December 31, 2021, the Company had recognized $258,887 in expenses
associated with this MSA, of which $219,823 were charged against cash advanced under the terms of the Amendment, leaving no additional
expenses to be recognized under this agreement.
In addition, Dr. Johnson executed a guaranty,
dated December 12, 2019, of PEPCO’s performance under the MSA and SOW (the “Guaranty”), together with a pledge and security
agreement, dated December 12, 2019 (the “Pledge and Security Agreement”), to secure the Guaranty with 600,000 shares of our
common stock beneficially owned by him and a lock-up agreement, dated December 12, 2019 (the “Lock-Up”), pursuant to which
he agreed not to transfer or dispose of, directly or indirectly, any shares of our common stock, as currently owned by him, until after
January 1, 2021.
On August 19, 2020, we and Dr. Bankole Johnson
entered into a Lock-Up Agreement Extension and Right of First Refusal (the “Lock-Up Extension”), which amended the Lock-Up
Agreement that they had entered into dated December 12, 2019 (the “Lock-Up”). The Lock-Up Extension extended the term of Dr.
Johnson’s Lock-Up from January 1, 2021 until April 1, 2021. In connection with the Lock-Up Extension, Dr. Johnson was released from
his Lock-Up restrictions with respect to 350,000 shares of our common stock, in order to enable Dr. Johnson to fund his new clinic focused
on brain wellness and addiction treatments, Privée Clinics, LLC. Additionally, under the Lock-Up Extension, we were granted a right
of first refusal for future financings in Privée Clinics, LLC
On May 11, 2021, we entered into an Amendment
2 (the “Amendment 2”) to the SOW. Under Amendment 2, we agreed to pay PEPCO and additional $25,000 due to the change of scope
due to the increased number of clinical sites initiated and trained as part of the ONWARD Phase 3 trial.
Protection from Generic Competition
Since our inception, we have focused on taking
action primarily through the filing of patents geared toward ensuring AD04 will have market exclusivity for at least 10 years after it
is launched with particular focus on the U.S. and Europe. Ondansetron, the active pharmaceutical ingredient (“API”) of AD04
was granted FDA approval as Zofran® for the treatment of post-operative and post-chemotherapy nausea and emesis in January
1991 and is now commercially available in generic form at doses from more than 12 times the AD04 dose to over 70 times the AD04 dose with
the highest doses being administered intravenously (“i.v.”), which provides almost twice the drug exposure levels as oral
dosing. With generic ondansetron available, the following threats have been addressed: (i) the potential use of currently available ondansetron
products (i.e., Zofran®) “off-label”, and (ii) the potential manufacturing and launching of a generic version
AD04 by a competitor.
Limited Threat of “Off-label” Use
of Zofran ®
The lowest doses of Zofran® tablets
(and its generic equivalents) on the market are a 4 mg and 8 mg tablet as compared to AD04, which is currently formulated as a 0.33 mg
tablet (12.2 times less than the 4 mg tablet). Thus, in order for a patient to use tablets already on the market and get the AD04 dose,
a patient would have to cut the 4 mg tablet into 12 parts (or the 8 mg tablet into 24 parts), which we do not believe is reasonably possible;
and, even with precise sectioning into 12 pieces, the dose may still not be accurate because tablets at the Zofran® dose
have not been manufactured to ensure uniformity of distribution of the active ingredient across the tablet. Therefore, we believe that
the risk of a large number of patients attempting to cut the currently marketed tablet to achieve the AD04 dose to be extremely low.
Since we do not believe that Zofran®
tablets can be used as a substitute for AD04, the main question related to the potential for off-label use of the current products for
treating addictions then becomes whether doctors and patients will believe it is possible to use the currently available, higher doses
of ondansetron to treat addictions, including AUD. We believe doctors are extremely unlikely to prescribe currently available high dose
versions of ondansetron and that any such prescribing that dose will likely be limited and immaterial to the sales of AD04 for two reasons
— (1) we believe the high doses are unlikely to be efficacious as a treatment for AUD, and (2) we believe the high doses would likely
raise significant safety concerns.
|
1. |
Lack of Efficacy. The high doses of ondansetron found in Zofran® have been tested in clinical trials for treating AUD and have not shown efficacy against AUD (Sellers, et. al. 1994). At best, existing trial results do not suggest that the high Zofran®-level doses of ondansetron currently on the market and approved for nausea and emesis will be effective. |
|
2. |
Safety Concerns. While high-dose ondansetron is safe and tolerable at the doses on the market if administered acutely (i.e., dosed for a few hours i.v. or a few days orally) as is done for post-operative and post-chemotherapy nausea and emesis, the drug is known to have cardiovascular side effects at higher doses, and results from clinical studies suggest that high doses of ondansetron may affect the electrical activity of the heart. In fact, the FDA withdrew approval of the 32 mg i.v. Zofran® product that was previously on the market. As part of the FDA’s on-going safety review of currently available ondansetron doses, the FDA has stated that: “Ondansetron at currently marketed levels may increase the risk of developing prolongation of the QT interval of the electrocardiogram, which can lead to an abnormal or potentially fatal heart rhythm.” There are also several recent lawsuits claiming that Zofran® used for off label for morning sickness causes birth defects. Thus, if the currently available high-dose ondansetron was used chronically as would be needed for treating addiction there could potentially be significant safety concerns without additional clinical studies related to the chronic dosing of currently available ondansetron. At the lower dose of ondansetron in AD04, our product is almost as low as one one-hundredth of the dose of i.v. ondansetron that was removed from the market. The FDA has stated that we can commence chronic dosing of patients with AD04 without any further safety or non-clinical studies. |
Therefore, we do not expect physicians to prescribe
current ondansetron doses for currently unapproved use for treating AUD because there is no evidence those doses would work for treating
AUD and there may be safety concerns associated with the chronic administration of currently available doses.
There is also a liquid, pediatric formulation
of Zofran® on the market. It is offered in a 50 mL bottle that is available for a little over $100 online and would provide
a 2-month supply of AD04 if dosed at the 0.4 mL required to achieve the 0.33 mg AD04 dose. Our risk assessment is that, though it would
be possible to use the liquid formulation for administering a dose of ondansetron equivalent to AD04, it is not expected to be a practice
that would materially impact the sales of AD04, and the risk from the liquid formulation is low for the following reasons:
|
1. |
Compliance concerns. In the field of addiction, patient compliance is one of the biggest concerns for both the physicians and the patients themselves. A treatment not appropriately administered is a treatment that will not work. Oral tablets have been shown to have one of the highest compliance rates over other dosage forms. It is likely that both physicians and patients will demand the tablet in order to improve compliance and, thus, treatment success rates. |
|
2. |
Inconvenient, complicated delivery. A major driver of compliance is the convenience of appropriately administering the drug. Appropriate delivery of the liquid formulation would require patients to measure each dose into a graduated dropper or syringe (administration of such a small amount (0.4 mL) by graduated cup would not be practical). Cleanup of the sticky product would be inconvenient as would transportation and storage, and an opened bottle would need to be used within 4 weeks (per UKPAR). Therefore, we expect that AD04’s convenient tablet would increase patient compliance relative to the liquid formulation. Bottle breakage and spillage will also be a concern. |
|
3. |
Dosing Accuracy. Dosing accuracy is particularly important when using ondansetron to treat alcoholism due to the limitations of the therapeutic window and the cardiovascular side effects at high doses. With the liquid formulation, measuring the small (0.4 mL) dose will be difficult with great opportunity for misdosing even if a graduated syringe is used. In real-world practice, many patients would use other methods such as estimated pouring into cups and drinking directly from the bottle. Misdosing could significantly affect the safety and/or efficacy of the treatment. |
|
4. |
Lack of physician motivation to prescribe the liquid formulation. Given the known compliance advantages of oral tablets vs. liquid formulations, the heightened need for compliance in this particular patient population, and the concerns around dosing accuracy with a liquid formulation, we believe it is likely physicians would recognize the risk of prescribing the liquid formulation off-label and so be unwilling to prescribe it. For insured patients, any differential in co-payments would create little incentive to use the liquid formulation relative to the compliance and inconvenience problems. |
|
5. |
Lack of competitive marketing. Manufacturers of liquid ondansetron are not allowed to market for reduction in alcohol use disorder because reduction in alcohol use disorder is not an approved indication for their product. Furthermore, most generic companies do not have marketing efforts of any kind. |
|
6. |
Litigation risk to large prescribers. If a large clinic (such as a rehabilitation clinic) prescribes or provides the liquid formulation off-label, the institution could be liable for inducing infringement of our licensed patents. |
In summary, we do not expect off-label use of
currently available ondansetron to meaningfully impact the sales of AD04.
Protection from a Competitor Launching a Generic
Version of AD04.
We believe that we have licensed the patent protection
necessary to protect us against the launch by a competitor of a generic version of AD04. The label being sought for AD04 will be:
The use of AD04 (i.e., ondansetron) for the treatment
of patients that are positive for the specified genetic markers.
The only use for the AD04 dose of ondansetron
will be under this label.
Our licensed patents cover the following:
The use of AD04 (i.e., ondansetron) for the treatment
of patients that are positive for the specified genetic markers.
We believe that any attempt by competitors to
reformulate and market ondansetron at our intended dosage levels, while technically feasible, can be interpreted under current case law
as inducement to infringe on our intellectual property rights, which should, accordingly, be actionable. Additionally, there will be no
unpatented use for the AD04 dose of ondansetron. So, a competitor that sells a product containing the AD04 dose of ondansetron will indirectly
infringe our licensed patents, which should, accordingly, be actionable.
A competitor could sell a dose equal to that of
AD04 and avoid our licensed patents if they conduct a Phase 3 program using the AD04 dose to treat a different label indication and achieved
successful results and approval. We do not know of any clinical development programs of ondansetron underway at this time and so consider
this risk to be negligible.
Purnovate and the Adenosine Platform
Overview –Unlocking the Promise of Adenosine
Purnovate, Inc. (“Purnovate”) is a
development-stage biopharmaceutical company focused on the development of therapeutic agents that selectively activate or block one or
more of the adenosine receptors (i.e., selective agonists and antagonists). We believe we have developed novel chemistries that change
the physical properties relative to historical adenosine analogs (i.e., molecules related to the adenosine neurotransmitter) to allow
us to create novel and patentable new chemical entities (“NCE’s”) (i.e., novel molecules/drug candidates) that are selective
and potent against the targeted receptors while also having the physical properties to allow significant tissue penetration – our
Adenosine Platform. This is expected to allow us to unlock the previously elusive promise of adenosine compounds and target large unmet
medical needs. Initial targets include, without limitation, pain, cancer, asthma, diabetes, and inflammatory diseases and disorders such
as wound/burn healing, inflammatory bowel disorder, and infectious diseases where cytokine storms play a significant role (i.e., COVID,
MRSA, sepsis). All of Purnovate’s compounds are currently pre-clinical; we expect our first clinical trial using a drug candidate
developed using the Purnovate adenosine platform to commence in the fourth quarter of 2022.
Purnovate was founded to invent and develop drug candidates based on
what we believe are the breakthrough chemistry concepts of our founding scientist, Dr. Robert D. Thompson, to allow the creation of molecules
for the treatment of serious diseases and disorders.
For a compound to have a high probability of being successfully developed
into a drug, we believe it is important that it be stable (e.g., will not degrade before it can be dosed, which historically has not been
a problem for adenosine analogs) and have the following characteristics:
| ● | Potency (e.g., bind to target receptors strongly so that it can compete with naturally occurring molecules attempting to also
bind to the target receptor) |
| | |
| ● | Selectivity (e.g., bind to target receptors while not binding to receptors that will cause undesirable side effects) |
| | |
| ● | Biodistribution (e.g., the ability to reach and penetrate in vivo to the target tissues) |
| | |
| o | Solubility (e.g., ability to dissolve in water) is often an indicator of whether a molecule will achieve oral bioavailability
and tissue penetration as humans/mammals are largely made of water. |
Historically, adenosine analogs have been able to achieve one or two
of the above stated characteristics and therefore had either limited efficacy or side effects that limit their usefulness. We believe
our Adenosine Platform already has developed molecules with the above characteristics and that it will continue to allow invention of
additional molecules with those characteristics.
Purnovate also has a proprietary purification technology developed
by Dr. Thompson. This technology allows us to rapidly and cost effectively produce novel compounds, which is one of the reasons we have
been so successful to date with new compounds in less than two years of chemistry operations.
We also believe the physical property changes that we have already
successfully applied to adenosine compounds may be useful in chemical classes outside of the field of adenosine and intend to explore
expansion beyond adenosine analogs in the future.
Purnovate Strengths
We believe Purnovate’s competitive strengths include the following:
|
● |
A highly experienced scientific and business leadership team with decades of experience in both drug development and commercialization and, in particular, in the development of adenosine analogs. |
| ● | We have already validated the Adenosine Platform, having invented and produced adenosine compounds with physical and in vivo behavioral
characteristics we believe have never been demonstrated before. |
| ● | Pharmacologic targets that are well-characterized, including often
having demonstrated human activity. |
| ● | Expected intellectual property protection primarily based on novel
chemical entity composition of matter patents expected into the late 2040’s with currently filed patent applications and their expected
extensions with new patents expected to be filed. |
Purnovate Strategy
Purnovate’s mission is to develop new chemical entities to treat
large unmet medical needs.
Our focus will be on inventing and developing adenosine analogs that
are selective against the target receptor. Initially we will focus on inventing and developing compounds that target receptors that we
believe are validated to affect certain disease states, and, particularly, those where human efficacy has been demonstrated with drugs
that non-selectively bind to those receptors.
We plan to use a combination of self-development, partnerships with
pharmaceutical companies, and collaborations with top academic institutions to develop our programs. Our current intentions and strategy
are stated below
| ● | Retain the pain program due to it being an indication related to addiction; |
| ● | License non-pain and addiction programs to third-party pharmaceutical companies at the optimal time in the development cycle; |
| o | We currently expect to license our cancer program prior to clinical studies; |
| o | Other non-pain/addiction programs will be evaluated on a case-by-case basis for potential licensing timing. |
| ● | For certain programs, we will seek partnerships with leading medical research institutions to cost effectively develop and validate
the program; we have already entered an academic collaboration around our wound/burn healing program with the University of Virginia School
of Medicine. |
Why Adenosine?
Overview of Adenosine
Adenosine is an important neurotransmitter with numerous pharmacologic
actions, and it is naturally generated when needed, short acting, and acts locally. There are four adenosine receptor subtypes (A1, A2A,
A2B, and A3). Different tissues have different receptors and the pharmacologic actions of adenosine can impact or even sometimes drive
diseases and disorders.
Effects

Historically, other than drugs such as Adenocard® (for tachycardia)
and Adenoscan® and Lexiscan® (both for cardiac stress imaging) which work through cardiovascular effects and are for a short duration
of treatment, and adenosine related drugs and drug candidates, have been limited by cardiovascular effects due to binding to the adenosine
A1 receptor (“A1R”).
Caffeine and Theophylline
Caffeine is an example of an adenosine analog
that is limited by cardiovascular side effects. Caffeine is a non-selective adenosine antagonist (i.e., a blocker), meaning that it blocks
all four of the adenosine receptors with almost equal potency. It also is a relatively weak/non-potent adenosine blocker with a binding
affinity (i.e., Kd; see “A Comparison” below) of greater than 10,000 nM at all adenosine receptors (we consider a Kd of 150
nM or less to be potent). While caffeine is known to have a pain reduction effect and is approved for pain reduction (e.g., Excedrin®,
Anacin®), its dose must be limited or it will create undesirable cardiovascular effects by blocking the heartbeat regulating
effect of adenosine activation of the A1R on heart muscle when the heart starts beating too fast, and by creating insomnia by blocking
adenosine activation of the A1R in the brain to create relaxation to enable sleep. We believe we have a drug candidate, PNV-5030 (see
Our Initial Products below), that is more than 3,000 times more potent than caffeine at the target receptor, but that does not block the
A1R and therefore will not have cardiovascular or wakefulness effects like caffeine.
Theophylline is another drug believed to work largely through adenosine
blockade. While it works for asthma, like caffeine, it is non-selective and therefore has side effects such as chest pain, irregular heartbeat,
and sleeplessness which make using it unpleasant and so limit its usefulness. We believe we can develop a drug that has the asthma effects
of Theophylline without the undesirable side effects that limit its use (Barnes, “Theophylline”, American Journal of Respiratory
and Critical Care Medicine).
A Comparison
A table listing characteristics of a number of
currently known adenosine analog compounds and some of our already-invented compounds is below.
In the above table:
| ● | a compound is considered soluble if 25 micrograms of the compound can be dissolved in water at 25 degrees Celsius. |
| ● | A compound is considered potent if it has a binding affinity (i.e., Kd) of less than 150 nanomolar. Binding affinity is a measure
of how much compound is required to bind to 50% of the receptors in the experiment. A lower Kd means the compound has a greater affinity
(i.e., potency) for the receptor. |
|
● |
A compound is considered selective if it has a binding affinity for the targeted receptor (i.e., the receptor intended to be activated or blocked by the drug to achieve the desired pharmacologic effect) that is 1,000 times greater than the any of the adenosine receptor or receptors not targeted. Etrumadenant is the only one in the table targeted for two receptors (i.e., dual-acting blocker of the A2A and A2B receptors). |
Safety and Tolerability
As noted above, compounds that have potency on the A1R receptor can
have problematic safety and tolerability issues. However, previous work with compounds that are selective over the A1R have been taken
into clinical testing with limited side effects. We believe the adenosine receptors we are targeting and intend to target, assuming we
can achieve selectivity over the other receptor as we believe we can, will not cause problematic safety issues with the doses we expect
to use.
Our Industry
The pharmaceutical industry is extremely competitive. If any of the
products developed from our technologies are approved, they will likely compete in a highly competitive market. Our competitors in this
market may succeed in developing products that could render our product candidates obsolete or non-competitive. Many of our potential
competitors have significantly more financial, technical and other resources than we do, which may give them a competitive advantage.
In addition, they may have substantially more experience in effecting strategic combinations, in-licensing technology, developing drugs,
obtaining regulatory approvals, manufacturing and marketing products. We cannot give any assurances that we can compete effectively with
these other biotechnology and pharmaceutical companies.
Our Initial Products
We are initially developing adenosine analogs and have developed compounds
with varying characteristics targeting the adenosine 2A receptor (“A2AR”) and the adenosine A2B receptor (“A2BR”).
Target indications so far include pain, cancer, asthma, diabetes, and inflammatory diseases and disorders such as wound/burn healing,
inflammatory bowel disorder, and infectious diseases where cytokine storms play a significant role (i.e., COVID, MRSA, sepsis).
Pain
Pain is a large market in the US with as many as 1 in 5 Americans suffering
from chronic pain, not including acute pain. In 2016, an estimated 20.4% of U.S. adults (50.0 million) had chronic pain and 8.0% of U.S.
adults (19.6 million) had high-impact chronic pain (www.cdc.org), with higher prevalence associated with advancing age.
Source: GBD Results Tool Results (https://ghdx.healthdata.org/gbd-results-tool)
The total patients of pain increased from 119 Mn in 2015 to 132
Mn in 2019
PNV-5030
PNV-5030 has been selected as a lead compound for the treatment of
pain. Pre-clinical development has commenced and we intend to file an Investigational New Drug Application (an “IND”) this
year with a plan to also commence a Phase 1 clinical trial in 2022.
PNV-5030 has currently passed our in vitro toxicology screening
and is currently being produced at a third party manufacturing vendor so that full toxicology studies may be conducted to enable the commencement
of clinical studies in 2022 as noted above.
PNV-5030 has demonstrated in vivo efficacy in models of both
nociceptive (i.e., peripheral) pain and neuropathic pain as stated below.
PNV-5030 was tested in a mouse model of somatic
nociceptive pain where discomfort was initiated using a laser focused on the mouse’s tail, with the time before the mouse flicked
its tail away being measured by a sensor. Response groups of 12 mice were analysed with a control group receiving vehicle alone (i.e.,
liquid dosing solution without any drug) and other groups receiving either 1mg/kg or 2mg/kg doses of morphine, a common opioid pain relief
medication, alone; PNV-5030 alone; or morphine plus PNV-5030.
PNV-5030 alone exhibited a significant pain reduction
as compared to the control group and a similar effect to 1mg/kg morphine. Importantly, PNV-5030 demonstrated a significant effect when
administered with 1 mg/kg morphine as compared to administering 1 mg/kg morphine alone. Interestingly, when combined with 1 mg/kg morphine,
PNV-5030 achieved a similar level of pain reduction to the reduction obtained with 2mg/kg morphine. We believe these results could indicate
the possibility of lowering the opioid dose to achieve a similar pain reduction level by combining an opioid with PNV-5030 or even eliminating
the use of an opioid for pain relief in favor of a higher dose of PNV-5030.
Notably, certain mice in both the PNV-5030 plus morphine groups achieved
results at the maximum time allowed under the study (15 seconds), and, therefore, may have shown even greater pain reduction results had
the protocol allowed continuation of the test beyond the time limit. The data are shown in the following chart:
Cancer
Cancer Market
Each year in the United States, more than 1.6
million people are diagnosed with cancer, and nearly 600,000 die from it, making cancer the second leading cause of death. The cost of
cancer care continues to rise and is expected to reach almost $174 billion by 2020 (source www.cdc.gov). The current overall annual health
care spending for privately insured patients younger than age 65 in the US with the 15 most prevalent cancers is $156.2 billion (Source:
Zaorsky M et al. JAMA Netw Open. 2021;4(10):e2127784. Data indicate that patients with breast, colorectal, and prostate cancer had the
greatest number of services performed, and the plurality of these services were attributable to pathology and laboratory tests.

In vivo Proof of Concept/Pre-lead
One of our compounds, PNV2, has demonstrated positive pre-clinical
data in an animal model of triple negative breast cancer (TNBC). PNV2 was tested in a metastatic breast cancer model with the primary
endpoint being the amount of cancer metastases into the lungs after 28 days following orthotopic implantation of breast cancer.
Study highlights:
| ● | Luciferase-engineered triple-negative breast cancer (TNBC) cells MDA-MB-231 were implanted in the mammary fat pad in female mice. |
| ● | Tumors grew over 28 days and were treated intratumorally three times a week. |
| ● | An active group (n=10) was treated with PNV2 in solution and a control group (n=10) was treated with only the solution. |
| ● | Metastasis into the lungs was then determined by measuring the amount of luciferase activity, which indicates the amount of cancer
in the lungs. |
| ● | In the control group, 30% of the mice had large, well-established secondary tumors (i.e., metastatic, invasive tumors) in their lungs
with luciferase activity of greater than 1585 AU in each mouse, while the PNV2 group appeared to have no large secondary tumors in the
lungs of any mouse and luciferase activity of not more than 356 AU in any mouse. |
We intend to test additional compounds to choose a lead for our first
cancer indication, including testing in both immunogenic and non-immunogenic animals.
Development Plan
We intend to develop our cancer program until it is approved for clinical
testing or in early clinical testing, which point we would expect to license the program to a third-party pharmaceutical company focused
on developing treatments for cancer.
Asthma
Asthma Market
Approximately 25 million Americans have asthma. This equals to about
1 in 13 Americans and 10 people in the U.S. die from asthma every day. (www.aafa.org). About 8 percent of adults and 7 percent of children
have asthma. Asthma is more common in adult women than adult men. The asthma market has been seeing a steady growth due to the increase
in prevalence of the disease at a CAGR of 1.6%.

In vivo Proof of Concept/Pre-lead
One of our compounds, PNV-5032 demonstrated a
significant inhibition of pulmonary flow resistance, which is a measure of asthmatic response, in an in vivo sheep model of asthma.
PNV-5032 Relevant Information
| ● | Greater than 1000-fold selective over the adenosine A1 receptor in potency assays |
| ● | Demonstrated solubility more than 100 times greater than other selective adenosine compounds of the same
class currently known to Purnovate |
| ● | Solubility of an inhaled product allows dissolution in the aerosolized mist for fine distribution over
the bronchioles and can be important in facilitating bronchiole membrane penetration |
| ● | Findings indicate drug development potential of molecules of this class, possibly to treat asthma |
| ● | Covered by a composition of matter patent application for patent protection through 2042 with expected
statutory extension to 2047 |
Study Design
Sheep, which respond to allergens and adenosine
challenges in a manner similar to humans, were initially challenged with an aerosolized dose of Ascaris Sum allergens. Sheep are naturally
allergic to these antigens, derived from intestinal roundworms, and each animal responded with severe bronchoconstriction, a clinically
relevant symptom shared with asthma patients.
After a washout/recovery period of a few weeks,
PNV-5032 was nebulized and administered prophylactically to the sheep. Fifteen minutes later, the sheep received another aerosolized dose
of Ascaris Sum allergens. Breath-by-breath determination of mean pulmonary flow resistance was measured with the esophageal balloon technique
over four hours post challenge, corresponding to the early asthmatic reaction. Each animal served as its own control.
Study Results
A significant 25% reduction in airflow resistance
in the PNV-5032 group was observed as compared to the control group (5.1+/- 0.3 vs 6.9+/- 0.5 cm H2O/L/s, respectively).
Development Plan
We intend to develop our asthma program with a
plan to develop it internally through early Phase 2 clinical testing (i.e., human proof of concept). We would expect to then evaluate
whether to keep the program or seek a pharmaceutical partner focused on pulmonary indications.
Type II Diabetes
Type II Diabetes Market
Diabetes is a huge market in US with more than 37 million Americans
having diabetes (about 1 in 10), and approximately 90-95% of them have type 2 diabetes. Type 2 diabetes most often develops in people
over age 45, but more and more children, teens, and young adults are also developing it (www.cdc.org). The prevalence of Type II diabetes
has increased from 32.2 Mn patients in 2015 to 36.2 Mn patients in 2019 with a CAGR of 2.4%.

In vivo Proof of Concept
We have achieved early proof of concept in vivo in reducing
glucose levels in insulin insensitive mice when the mice are treated with our compounds and glucose is administered as compared to glucose
administered alone. We are still optimizing compounds prior to moving toward lead selection.
Development Plan
We intend to develop our Type II program with
a plan to develop it internally through early Phase 2 clinical testing (i.e., human proof of concept). We would expect to then evaluate
whether to keep the program or seek a pharmaceutical partner focused on metabolic indications.

Collaboration with the University of Virginia
We have entered a collaboration research agreement with Dr. Mark Roeser
at the University of Virginia School of Medicine to develop new formulations of Purnovate’s proprietary adenosine compounds for
wound healing through transdermal administration (i.e., through the skin). Under the Agreement, we will supply certain lead adenosine
compounds and Dr. Roeser’s research team will be responsible for evaluating these compounds for efficacy and determination of the
ideal formulations for maximum absorption with the goal of initiating future clinical trials. The University of Virginia will fund the
pre-clinical research activities and the parties will jointly own intellectual property mutually developed.
Development Plan
We intend to develop our wound/burn healing program
in collaboration with the University of Virginia School of Medicine using limited funds from Purnovate and funding from grants from government
agencies such as the U.S. military and the National Institutes of Health (the “NIH”). To date we have not received any such
funding and there can be no assurance that such funding will be available to us. We will evaluate keeping the program in-house or seeking
a licensing partner as it readies to commence human testing.
Inflammatory Bowel Disease (“IBD”)
The IBD Market
IBD is a large problem in the US; in 2015 an estimated
3.1 million adults (1.3%) in the United States were diagnosed with inflammatory bowel disease (IBD), which includes Crohn’s disease
and ulcerative colitis (www.cdc.gov). The IBD market has been steady in last few years due to a constant disease prevalence. Source: GBD

We intend to develop our IBD program in collaboration
with a leading research institution using limited funds from Purnovate and funding from grants from private foundations, government agencies
such as the NIH. To date we have not received any such funding and there can be no assurance that such funding will be available to us.
We will evaluate keeping the program in-house or seeking a licensing partner as it readies to commence human testing.
Infectious Disease
The Infectious Disease Market:
The infectious disease market is broad in that
it covers any indication where pathogen driven inflammatory response (i.e., a cytokine storm) causes damage, disability or death above
and beyond the direct effect of the pathogen. Potential target indications include, without limitation, severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2), which causes COVID-19, methicillin-resistant staphylococcus aureus (MRSA), and sepsis in general, among others.
In 2017, an estimated 119,247 S. aureus bloodstream infections with
19,832 associated deaths occurred. During 2005–2012 rates of hospital-onset MRSA bloodstream infection decreased by 17.1% annually,
but the decline slowed during 2013–2016. Community-onset MRSA declined less markedly (6.9% annually during 2005–2016), mostly
related to declines in health care–associated infections. Hospital-onset MSSA has not significantly changed (p = 0.11), and community-onset
MSSA infections have slightly increased (3.9% per year, p<0.0001) from 2012 to 2017. Source: Kourtis A et. al., Weekly / March
8, 2019 / 68(9);214–219.
In the United States, over 970,000 sepsis cases
are admitted annually, and the numbers have been rising year over year. A two-decade study of U.S. hospitalizations identified an increase
in the incidence of sepsis among hospitalized patients by 8.7% per year. Additionally, sepsis accounts for more than 50% of hospital deaths,
and mortality increases dramatically with greater disease severity: 10–20% for sepsis, 20–40% for severe sepsis, and 40–80%
for septic shock. Source: Paoli C et al., Critical Care Medicine: December 2018 - Volume 46 - Issue 12 - p 1889-1897.

We intend to develop our Infectious Disease program
in collaboration with a leading research institution using limited funds from Purnovate and funding from grants from private foundations,
government agencies such as the U.S. military and the NIH. To date we have not received any such funding and there can be no assurance
that such funding will be available to us. We will evaluate keeping the program in-house or seeking a licensing partner as it readies
to commence human testing.
Chemistry and Manufacturing
We operate our own leased chemistry laboratories, which are collocated
with our corporate offices in approximately 4,175 square feet of leased space.
Our laboratories have chemical synthesis/production, purification and
analytical capabilities, including without limitation, high performance liquid chromatography (HPLC), mass spectrometry (LCMS), purification
column production, and access to structural elucidation through nuclear magnetic resonance (NMR). We invent and create molecules in this
laboratory and also produce gram-scale quantities for early testing. As we progress toward human testing, we will contract with third
party vendors for clinical trial material made under current good manufacturing practices (cGMP).
Purnovate Intellectual Property
All products we currently intend to pursue as
drug development candidates are expected to be internally invented, novel and patentable novel chemical entities (“NCE’s”).
Therefore, all of our products are expected to have “composition of matter” patent protection for twenty years (i.e., until
2041 or later), plus expected statutory extensions such as patent term adjustments under 35 U.S.C. § 154 or patent term extensions
under Drug Price Competition and Patent Term Restoration Act of 1984, PL 98-417, S 1538 98 Stat. 1585 (the “Hatch-Waxman Act”),
which, together, could extend the market exclusivity of our products for five years or more. For most products we also plan to pursue
use, formulation, and process patents to buttress our patent estate and product protection and which may further extend the duration of
our market exclusivity.
We believe our compounds represent a new generation
of adenosine analogs. Our composition of matter claims in the patent application are broad in the area of adenosine and, due to our knowledge
of the area, have been drafted to cover what we believe will be the most expansive adenosine patent estate in existence. Because of the
possible variations around our core inventions, the patents are expected to cover trillions of potential new compounds. We expect to continue
to expand our portfolio to cover additional compounds many times that number as we progress our chemistry program.
We also possess proprietary purification technology
developed by Dr. Thompson. This technology is protected as a trade secret.
Acquisition of Purnovate, LLC – Transaction

Governmental Regulation
Our business is subject to extensive laws and
regulations, the most significant of which are summarized below.
FDA Approval Process
In the United States, pharmaceutical products
are subject to extensive regulation by the FDA. The Federal Food, Drug, and Cosmetic Act (the “FDC Act”), and other federal
and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping,
approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of
pharmaceutical products. In the United States, pharmaceutical products used for the prevention, treatment, or cure of a disease or condition
of a human being are subject to extensive regulation under the FDC Act. Failure to comply with applicable U.S. requirements may subject
a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending NDAs, warning or untitled letters,
product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties, and
criminal prosecution.
Pharmaceutical product development for a new product
or certain changes to an approved product in the United States typically involves preclinical laboratory and animal tests, the submission
to the FDA of an investigational new drug application (“IND”), which must become effective before clinical testing may commence,
and adequate and well-controlled clinical trials to establish the safety and effectiveness of the drug for each indication for which FDA
approval is sought. Satisfaction of FDA pre-market approval requirements typically takes many years and the actual time required may vary
substantially based upon the type, complexity, and novelty of the product or disease.
Preclinical tests include laboratory evaluation
of product chemistry, formulation, and toxicity, as well as animal trials to assess the characteristics and potential safety and efficacy
of the product. The conduct of the preclinical tests must comply with federal regulations and requirements, including good laboratory
practices. The results of preclinical testing are submitted to the FDA as part of an IND along with other information, including information
about product chemistry, manufacturing and controls, and a proposed clinical trial protocol. Long-term preclinical tests, such as animal
tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.
A 30-day waiting period after the submission of
each IND is required prior to the commencement of clinical testing in humans. If the FDA has neither commented on nor questioned the IND
within this 30-day period, the clinical trial proposed in the IND may begin. However, the FDA can impose a clinical hold after 30 days
if it has safety or compliance-related concerns.
Clinical trials involve the administration of
the investigational new drug or biologic to healthy volunteers or patients under the supervision of a qualified investigator. Clinical
trials must be conducted: (i) in compliance with federal regulations; (ii) in compliance with good clinical practice (“GCP”),
an international standard meant to protect the rights and health of subjects and to define the roles of clinical trial sponsors, administrators,
and monitors; as well as (iii) under protocols detailing the objectives of the trial, the parameters to be used in monitoring safety,
and the effectiveness criteria to be evaluated. Each protocol involving testing on U.S. subjects and subsequent protocol amendments must
be submitted to the FDA as part of the IND.
As noted, the FDA may order the temporary, or
permanent, discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is
not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. The study protocol
and informed consent information for subjects in clinical trials must also be submitted to an institutional review board (“IRB”),
for approval. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply
with the IRB’s requirements, for safety or other concerns, or may impose other conditions.
Clinical trials to support NDAs for marketing
approval are typically conducted in three sequential phases, but the phases may overlap. In Phase 1, the initial introduction of the drug
or biologic into healthy human subjects or patients, the product is tested to assess metabolism, pharmacokinetics, pharmacological actions,
side effects associated with increasing doses, and, if possible, early evidence of effectiveness. Phase 2 usually involves trials in a
limited patient population to determine the effectiveness of the drug or biologic for a particular indication, dosage tolerance, and optimum
dosage, and to identify common adverse effects and safety risks. If preliminary evidence of effectiveness and an acceptable safety profile
in Phase 2 evaluations, Phase 3 trials are undertaken to obtain the additional information about clinical efficacy and safety in a larger
number of patients, typically at geographically dispersed clinical trial sites, to permit the FDA to evaluate the overall benefit-risk
relationship of the drug or biologic and to provide adequate information for the labeling of the product. In most cases, the FDA requires
two adequate and well-controlled Phase 3 clinical trials to demonstrate the efficacy of the drug or biologic.
After completion of the required clinical testing,
an NDA is prepared and submitted to the FDA. FDA approval of the NDA is required before marketing of the product may begin in the United
States. The NDA must include the results of all preclinical, clinical, and other testing and a compilation of data relating to the product’s
pharmacology, chemistry, manufacture, and control. The cost of preparing and submitting an NDA is substantial. The submission of most
NDAs is additionally subject to a substantial application user fee, currently exceeding $2.5 million for fiscal year 2019 (although a
waiver is possible in certain cases), and the manufacturer and/or sponsor under an approved new drug application are also subject to a
program fee set at more than $309,000 for fiscal year 2019. These fees are typically increased annually.
The FDA has 60 days from its receipt of an NDA
to determine whether the application will be accepted for filing based on the agency’s threshold determination that it is sufficiently
complete to permit substantive review. Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA has agreed
to certain performance goals in the review of NDAs. Most such applications for standard review drug or biologic products are reviewed
within ten to twelve months; most applications for priority review drugs or biologics are reviewed in six to eight months. The FDA can
extend these reviews by three months. The review process for both standard and priority review may be extended by the FDA for three additional
months to consider certain late-submitted information, or information intended to clarify information already provided in the submission.
The FDA may also refer applications for novel
drug or biologic products, or drug or biologic products that present difficult questions of safety or efficacy, to an advisory committee
— typically a panel that includes clinicians and other experts — for review, evaluation, and a recommendation on questions
raised by an application, including whether the application should be approved. The FDA is not bound by the recommendation of an advisory
committee, but it generally follows such recommendations. Before approving an NDA, the FDA will typically inspect one or more clinical
sites to assure compliance with GCP. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured.
The FDA will not approve the product unless compliance with current good manufacturing practice (“cGMP”) is satisfactory and
the NDA contains data that provide substantial evidence that the drug or biologic is safe and effective in the indication studied.
After the FDA evaluates the NDA and the manufacturing
facilities, it issues either an approval letter or a Complete Response Letter (“CRL”). In some cases, FDA may choose to extend
the review time, in consultation with the sponsor. A CRL generally outlines the deficiencies in the submission and may require substantial
additional testing, or information, in order for the FDA to reconsider the application. If, or when, those deficiencies have been addressed
to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing
such resubmissions in two or six months depending on the type of information included.
An approval letter authorizes commercial marketing
of the drug or biologic with specific prescribing information for specific indications. As a condition of NDA approval, the FDA may require
a risk evaluation and mitigation strategy, or REMS, to help ensure that the benefits of the drug outweigh the potential risks. REMS can
include medication guides, communication plans for healthcare professionals, and elements to assure safe use (“ETASU”). ETASU
can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances,
special monitoring, and the use of patient registries. The requirement for a REMS can materially affect the potential market and profitability
of the product. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the product’s
safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems
are identified following initial marketing. The FDA could also impose a boxed warning (sometimes referred to as a Black Box Warning) in
the product label if it identifies a specific risk that requires particular attention. This imposition of a Black Box Warning limits certain
types of promotions.
Changes to some of the conditions established
in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and
FDA approval of a new NDA or NDA supplement before the change can be implemented.
Enacted in 2016, the 21st Century Cures
Act (the “Cures Act”), in part, revises the drug and device review and approval processes at the FDA. The Cures Act, which
was signed into law on December 13, 2016, among other things, requires the manufacturer of an investigational drug for a serious disease
or condition to make available, such as by posting on its website, its policy on evaluating and responding to requests for individual
patient access to such investigational drug. This requirement applies on the later of 60 calendar days after the date of enactment of
the Cures Act or the first initiation of a Phase 2 or Phase 3 trial of the investigational drug.
The FDA has various programs, including fast track
designation, accelerated approval, priority review, and breakthrough therapy designation, which are intended to expedite or simplify the
process for the development and FDA review of drugs that are intended for the treatment of serious or life-threatening diseases or conditions
and demonstrate the potential to address unmet medical needs. We believe AD04 may qualify for one or more of these programs and intend
to purse one or more of them as part of our strategy to expedite the approval of AD04 for marketing.
Post-Approval Requirements
Once an NDA is approved, a product will be subject
to certain post-approval requirements. For instance, the FDA closely regulates the post-approval marketing and promotion of drugs and
biologics, including standards and regulations for direct-to-consumer advertising, industry-sponsored scientific and educational activities
and promotional activities involving the internet. Drugs and biologics may be marketed only for the approved indications and in accordance
with the provisions of the approved labeling.
Adverse event reporting and submission of periodic
reports is required following FDA approval of an NDA. The FDA also may require post-marketing testing, known as Phase 4 testing, REMS,
and special surveillance to monitor the effects of an approved product, or the FDA may place other conditions on an approval that could
restrict the distribution or use of the product. In addition, quality control, drug manufacture, packaging, and labeling procedures must
continue to conform to cGMPs after approval. Drug and biologic manufacturers must list the product with the FDA, and they and certain
of their subcontractors are required to register their establishments with the FDA and certain state agencies. Registration with the FDA
subjects entities to periodic unannounced inspections by the FDA, during which the agency inspects manufacturing and other facilities
to assess compliance with cGMPs and other requirements. Accordingly, manufacturers must continue to expend time, money, and effort in
the areas of production and quality-control to maintain compliance with cGMPs. Regulatory authorities may withdraw product approvals,
issue warning or other letters, suspend production activities, or request product recalls if a company fails to comply with regulatory
standards, or take other regulatory or enforcement action if it encounters problems following initial marketing, or if previously unrecognized
problems are subsequently discovered. Significant expenses are required to correct deficiencies.
Companion diagnostics and complementary
diagnostics
We believe that the success of our product candidates
may depend, in part, on the development and commercialization of either a companion diagnostic or complementary diagnostic. Companion
diagnostics and complementary diagnostics can identify patients who are most likely to benefit from a particular therapeutic product;
identify patients likely to be at increased risk for serious side effects as a result of treatment with a particular therapeutic product;
or monitor response to treatment with a particular therapeutic product for the purpose of adjusting treatment to achieve improved safety
or effectiveness. Companion diagnostics and complementary diagnostics are regulated as medical devices by the FDA and, as such, require
either clearance or approval prior to commercialization. The level of risk combined with available controls to mitigate risk determines
whether a companion diagnostic device requires Premarket Approval Application, or PMA, approval or is cleared through the 510(k) premarket
notification process. For a novel therapeutic product for which a companion diagnostic device is essential for the safe and effective
use of the product, the companion diagnostic device should be developed and approved or 510(k)-cleared contemporaneously with the therapeutic.
The use of the companion diagnostic device will be stipulated in the labeling of the therapeutic product. This is also true for a complementary
diagnostic, although it is not a prerequisite for receiving the therapeutic. Currently, we intend to submit a 505(b)(2) new drug application
to the FDA for AD04. We have interacted primarily with the FDA’s Center for Drug Evaluation and Research, in consultation
with the agency’s Center for Devices and Radiological Health. We expect to need approval of a PMA or a 510(k) from CDRH for the
companion diagnostics to be used with the drug product. If the FDA requires a separate application for the diagnostic, this could potentially
delay the approval of the new drug application for AD04, complicate the review process, or even lead to the rejection of the new drug
application.
Hatch-Waxman Amendments to the Federal Food,
Drug and Cosmetic Act
Under certain circumstances, an approved application
may be eligible for three years of non-patent market exclusivity provided by the Hatch-Waxman Amendments to the Federal Food, Drug, and
Cosmetic Act. The FDA might grant such exclusivity, (which would be separate from any patent protection to which an approved drug might
be entitled) if the applicant conducted new clinical investigations (other than bioavailability studies) that are new and essential to
the application’s approval. Among the types of exclusivity are those for a “new chemical entity” and those for a new
formulation or indication for a previously-approved drug. If granted, marketing exclusivity for the types of products that include only
drugs with innovative changes to previously-approved products using the same active ingredient, might prohibit the FDA from approving
an application for a competitor product, such as an abbreviated new drug application or a 505(b)(2) NDA relying on the finding of safety
and efficacy for three years. This three-year exclusivity, however, covers only the innovation associated with the original NDA. It does
not prohibit the FDA from approving applications for drugs with the same active ingredient but without the new innovative change. These
marketing exclusivity protections do not prohibit the FDA from approving a full NDA, even if it contains the innovative change. There
is no guarantee that the FDA will grant such exclusivity and competitors can try to seek approval of competitive products, notwithstanding
the exclusivity. However, if three years of exclusivity is afforded, it offers us one more barrier to competitor entry for a few years.
505(b)(2) NDA
For AD04, we intend to submit a 505(b)(2) NDA.
A 505(b)(2) NDA provided by Section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act, allows the FDA to rely, for approval of an
NDA, on data not developed by the applicant. Such an NDA, referred to as a 505(b)(2) application contains full reports of investigations
of safety and effectiveness, but where at least some of the information required for approval comes from studies not conducted by or for
the applicant and for which the applicant has not obtained a right of reference. Such applications permit approval of applications other
than those for duplicate products and permit reliance for such approvals on scientific literature or an FDA finding of safety and/or effectiveness
for a previously approved drug product. While each application is different, these types of applications will typically require bridging
studies (to support the change or modification from the listed drug) and could require clinical data to support the modification of the
already-approved drug product.
In addition, a 505(b)(2) NDA requires the applicant
to certify as to any patents that claim the drug for which a claim of patent infringement could be made. In certain cases, the applicant
of the NDA with a patent certification must provide notice to the patent holder, which can lead to a patent infringement lawsuit, thereby
delaying the FDA approval of the competitor product for up to 30 months, separate from any traditional patent infringement litigation
delay. Similarly, if the competitor has its own market exclusivity, this can delay approval of the product. However, if a product obtains
exclusivity or patent protection, it can delay entry of competitors for several years.
Pediatric Information
Under the Pediatric Research Equity Act (“PREA”),
NDAs or supplements to NDAs must contain data to assess the safety and effectiveness of the drug for the claimed indications in all relevant
pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the drug is safe and effective.
The FDA may grant full or partial waivers, or deferrals, for submission of data. We plan to test AD04 in adolescent patients (ages 12-17)
as part of our next Phase 3 trial. If successful, we intend to request labeling for treating adolescent patients.
Fraud and Abuse and Other Healthcare Regulation
We are subject to various federal and state healthcare
laws, including, but not limited to, anti-kickback laws. Penalties for violations of these healthcare laws include, but are not limited
to, criminal, civil and/or administrative penalties, damages, fines, disgorgement, individual imprisonment, possible exclusion from Medicare,
Medicaid and other federal and state healthcare programs, and the curtailment or restructuring of operations.
Anti-Kickback Statute
The federal Anti-Kickback Statute prohibits persons
or entities from knowingly and willfully soliciting, offering, receiving or paying any remuneration, directly or indirectly, overtly or
covertly, in cash or in kind, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for or recommending
a good or service, or for the purchasing, leasing, ordering, or arranging for or recommending, any good, facility, service or item for
which payment may be made in whole or in part under federal healthcare programs, such as the Medicare and Medicaid programs. The federal
Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry.
The term “remuneration” expressly includes kickbacks, bribes, or rebates and also has been broadly interpreted to include
anything of value, including for example, gifts, discounts, meals, entertainment, the furnishing of supplies or equipment, credit arrangements,
payments of cash, waivers of payments, ownership interests and providing anything at less than its fair market value.
There are a number of statutory exceptions and
regulatory safe harbors protecting certain business arrangements from prosecution under the federal Anti-Kickback Statute. These statutory
exceptions and safe harbors set forth provisions that, if all their applicable requirements are met, will assure healthcare providers
and other parties that they may not be prosecuted under the federal Anti-Kickback Statute. The failure of a transaction or arrangement
to fit precisely within one or more applicable statutory exceptions or safe harbors does not necessarily mean that it is per se
illegal or that prosecution will be pursued. However, conduct and business arrangements that do not fully satisfy all requirements of
an applicable safe harbor may result in increased scrutiny by government enforcement authorities and will be evaluated on a case-by-case
basis based on a cumulative review of all of its facts and circumstances. Additionally, the intent standard under the federal Anti-Kickback
Statute was amended under the Affordable Care Act, to a stricter standard such that a person or entity no longer needs to have actual
knowledge of the statute or specific intent to violate it in order to have committed a violation. The Affordable Care Act provides that
the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes
a false or fraudulent claim for purposes of the federal civil False Claims Act, which is discussed below.
Federal Civil False Claims Act
The federal civil False Claims Act prohibits,
among other things, persons or entities from knowingly presenting or causing to be presented a false or fraudulent claim to, or the knowing
use of false statements to obtain payment from or approval by, the federal government. Suits filed under the federal civil False Claims
Act, known as “qui tam” actions, can be brought by any individual on behalf of the government. These individuals, sometimes
known as “relators” or, more commonly, as “whistleblowers”, may share in any amounts paid by the entity to the
government in fines or settlement. The number of filings of qui tam actions has increased significantly in recent years, causing more
healthcare companies to have to defend a case brought under the federal civil False Claim Act. If an entity is determined to have violated
the federal civil False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil
penalties for each separate false claim. Many comparable state laws are broader in scope and apply to all payors, and therefore, are not
limited to only those claims submitted to the federal government.
Federal Physician Self-Referral Prohibition
We may also be subject to the federal physician
self-referral prohibitions, commonly known as the Stark Law, which prohibits, among other things, physicians who have a financial relationship,
including an investment, ownership or compensation relationship with an entity, from referring Medicare and Medicaid patients for designated
health services (which include clinical laboratory services) to such entity, unless an exception applies. Similarly, entities may not
bill Medicare, Medicaid or any other party for services furnished pursuant to a prohibited referral. Many states have their own self-referral
laws as well, which in some cases apply to all third-party payors, not just Medicare and Medicaid.
Federal Civil Monetary Penalties Statute
The federal Civil Monetary Penalties Statute,
among other things, imposes fines against any person or entity who is determined to have presented, or caused to be presented, claims
to a federal healthcare program that the person knows, or should know, is for an item or service that was not provided as claimed or is
false or fraudulent.
Health Insurance Portability and Accountability
Act of 1996
The federal Health Insurance Portability and Accountability
Act (“HIPAA”) created several new federal crimes, including healthcare fraud and false statements relating to healthcare matters.
The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, including
private third-party payors. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material
fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits,
items or services.
In addition, HIPAA, as amended by the Health Information
Technology for Economic and Clinical Health Act (“HITECH”), and their implementing regulations established uniform standards
for certain covered entities, which are healthcare providers, health plans and healthcare clearinghouses, as well as their business associates,
governing the conduct of specified electronic healthcare transactions and protecting the security and privacy of protected health information.
Among other things, HITECH also created four new tiers of civil monetary penalties and gave state attorneys general new authority to file
civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs
associated with pursuing federal civil actions.
The Federal Physician Payments Sunshine
Act
The federal Physician Payment Sunshine Act requires
certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the
Children’s Health Insurance Program, with certain exceptions, to report annually to CMS, information related to “payments
or other transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors)
and teaching hospitals, and to report annually to CMS ownership and investment interests held by physicians, as defined above, and their
immediate family members. Failure to submit timely, accurately and completely the required information for all payments, transfers of
value and ownership or investment interests may result in civil monetary penalties of up to an aggregate of $150,000 per year and up to
an aggregate of $1.0 million per year for “knowing failures.”
State Law Equivalents
Many states have also adopted laws similar to
each of the above federal laws, such as anti-kickback and false claims laws, which may be broader in scope and apply to items or services
reimbursed by any third-party payor, including commercial insurers, as well as laws that restrict our marketing activities with health
care professionals and entities, and require us to track and report payments and other transfers of value, including consulting fees,
provided to certain healthcare professionals and entities. Some states mandate implementation of compliance programs to ensure compliance
with these laws. We also are subject to foreign fraud and abuse laws, which vary by country.
Healthcare Reform
In March 2010, President Obama signed into law
the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the “ACA”),
which has the potential to substantially change healthcare financing and delivery by both governmental and private insurers, and significantly
impact the drug and medical device industries. The ACA will impact existing government healthcare programs and will result in the development
of new programs.
In addition, the ACA and its implementing regulations,
among other things, revised the methodology for calculation of rebates owed by manufacturers to the state and federal government for covered
outpatient drugs and certain biologics, including AD04 or any future product candidates, under the Medicaid Drug Rebate Program, increased
the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, extended the Medicaid Drug Rebate program
to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations, subjected manufacturers to new annual
fees and taxes for certain branded prescription drugs, and provided incentives to programs that increase the federal government’s
comparative effectiveness research.
Other legislative changes have been proposed and
adopted in the United States since the Affordable Care Act was enacted. In August 2011, the Budget Control Act of 2011, among other things,
created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted
deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the
legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers
up to 2% per fiscal year. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012 (the “ATRA”)
which delayed for another two months the budget cuts mandated by these sequestration provisions of the Budget Control Act of 2011. In
March 2013, the President signed an executive order implementing sequestration, and in April 2013, the 2% Medicare payment reductions
went into effect. The ATRA also, among other things, reduced Medicare payments to several providers, including hospitals, imaging centers
and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers
from three to five years.
In addition, Congress often uses the Medicare
program for pay for legislation. For example, on April 16, 2015, President Obama signed into law the “Medicare Access and CHIP Reauthorization
Act of 2015” (“MACRA”). MACRA repealed the Medicare sustainable growth rate formula that had been used to determine
payment levels under the Medicare physician fee schedule (“PFS”), and established a new method to update payments for physicians
and other providers paid under the PFS. Congress reduced Medicare payments for several categories of providers and made changes to Medicare
policies to offset the cost of the bill. It is possible that future legislation and regulations may include Medicare payment reductions
or policy changes that result in reduced payments, increased burdens or increased operating costs.
The full impact of the ACA, as well as other laws
and reform measures that may be proposed and adopted in the future, remains uncertain, but may continue the downward pressure on medical
device pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs, which could have
a material adverse effect on our business operations. Efforts to significantly amend or repeal the ACA continue and if passed could have
a significant impact on important aspects of our business including medical device and drug pricing, Medicare payment reductions or policy
changes that result in reduced payments, or increased burdens or operating costs.
The Foreign Corrupt Practices Act
The Foreign Corrupt Practices Act (“FCPA”),
prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering of anything of value, directly or
indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of such foreign
official in her or her official capacity or to secure any other improper advantage in order to obtain or retain business. In addition
to the antibribery provisions, the FCPA also obligates “issuers,” companies whose securities are registered pursuant to Section
12 of the Exchange Act or is required to file periodic and other reports with SEC under Section 15(d) of the Exchange Act to comply with
the FCPA’s record keeping and internal controls provisions; the accounting provisions require a listed company to maintain books
and records that, in reasonable detail, accurately and fairly reflect all transactions of the corporation, including international affiliates,
and to devise and maintain an adequate system of internal accounting controls to assure management’s control authority, and responsibility
over the company’s assets.
Export Controls and Economic Sanctions
Several U.S. statutes and regulations regulate
the export from the United States of pharmaceutical products. Pursuant to the Export Administration Regulations, (“EAR”) the
export (including re-exports and “deemed exports”) of commercial and “dual-use” products may require a license
or be prohibited. A listing of the types of goods and services controlled for export by the EAR is on the Commerce Control List (“CCL”),
which includes essentially all civilian science, technology, and engineering dual use items. For products listed on the CCL, a license
will be required as a condition to export, unless an exclusion or license exception applies. Those items not explicitly included on the
CCL are included in a broad category known as “EAR99.” Although a license may not generally be required for EAR99 designated
items, a license will be required if the item will be shipped or otherwise transferred to a comprehensively embargoed country or for a
potentially prohibited purpose.
The Commerce Department’s Office of Antiboycott
Compliance and the Treasury Department’s Internal Revenue Service enforce anti-boycott compliance regulations that prohibit U.S.
persons such as the Company from participating directly or indirectly with an economic boycott that is not recognized by the United States.
The regulations include reporting requirements, prohibitions, and tax liabilities that may be incurred if the Company supports, even inadvertently,
an economic boycott in which the U.S. does not participate.
Pursuant to the Trading With the Enemy Act, the
International Emergency Economic Powers Act, and other related statutes, regulations, and Executive Orders, the Treasury Department’s
Office of Foreign Assets Control (“OFAC”), administers and enforces economic and trade sanctions that prohibit or restrict
certain activities with embargoed countries, sanctioned entities, and sanctioned individuals for particular foreign policy and national
security reasons. The scope of the sanctions varies significantly, but may include comprehensive restrictions on imports, exports, investment,
and facilitation of foreign transactions involving a sanctioned jurisdiction, entity or person, as well as non-sanctioned persons and
entities acting on behalf of sanctioned jurisdictions, entities or people. OFAC’s programs also prohibit U.S. persons, such as the
Company, from transacting with any person or entity that is deemed to be a Foreign Sanctions Evader (foreign individuals and entities
determined to have violated, attempted to violate, conspired to violate, or caused a violation of U.S. sanctions).
Other U.S. government agencies, including the
U.S. Department of State, may maintain regulations that impact the Company’s ability to export pharmaceutical products from the
United States. These broad range of U.S. export control laws and regulations obligate U.S. businesses to develop, maintain, and enforce
an adequate system of internal controls to ensure compliance with such laws and regulations.
Implications of Being an Emerging Growth Company
We are an “emerging growth company,”
as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and therefore we intend to take advantage
of certain exemptions from various public company reporting requirements, including not being required to have our internal controls over
financial reporting audited by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act of
2002 (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in our periodic reports and
proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute
payments. We may take advantage of these exemptions until we are no longer an “emerging growth company.” In addition, the
JOBS Act provides that an “emerging growth company” can delay adopting new or revised accounting standards until such time
as those standards apply to private companies. We have elected to use the extended transition period for complying with new or revised
accounting standards under the JOBS Act. This election allows us to delay the adoption of new or revised accounting standards that have
different effective dates for public and private companies until those standards apply to private companies. As a result of this election,
our financial statements may not be comparable to companies that comply with public company effective dates. We will remain an “emerging
growth company” until the earlier of (1) the last day of the fiscal year: (a) following the fifth anniversary of the completion
of our initial public offering; (b) in which we have total annual gross revenue of at least $1.07 billion; or (c) in which we are deemed
to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeded $700.0 million
as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the
prior three-year period. References herein to “emerging growth company” have the meaning associated with that term in the
JOBS Act.

Human Capital/Employees
As of the date of this Annual Report on Form 10-K,
we have twenty-one employees, of which sixteen are full-time employees, one is a three-quarters time employee, one is a four-fifths time
employee, and three are variable hourly employees. Our Chief Medical Officer is a consultant that devotes 75% of his working time to providing
services to us. None of our employees is represented by a labor union, and we consider our relationship with our employees to be good.
We believe our relationships with our employees
are satisfactory. We anticipate that we will need to identify, attract, train and retain other highly skilled personnel to pursue our
development program. Hiring for such personnel is competitive, and there can be no assurance that we will be able to retain our key employees
or attract, assimilate or retain the qualified personnel necessary for the development of our business.
We have no collective bargaining agreements with
our employees and have not experienced any work stoppages. We consider our relations with our employees to be good. Although, management
continually seeks to add additional talent to its work force, management believes that it has sufficient human capital to operate its
business successfully.
Competitive Pay and Benefits. Our compensation
programs are designed to align the compensation of our employees with our performance and to provide the proper incentives to attract,
retain and motivate employees to achieve superior results. The structure of our compensation programs balances incentive earnings for
both short-term and long-term performance. Specifically:
|
● |
We provide employee wages that are competitive and consistent with employee positions, skill levels, experience, knowledge and geographic location. |
|
● |
Annual increases and incentive compensation are based on merit, which is communicated to employees at the time of hiring and documented through our talent management process as part of our annual review procedures and upon internal transfer and/or promotion. |
|
● |
All full-time employees are eligible for health insurance, paid and unpaid leaves, a 401K retirement plan with employer matching contributions (maximum of 4% match), and life insurance coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their needs, including flexible time-off, telemedicine, and paid parental leave. |
Description of Property
On March 1, 2020, the Company entered into a sublease
with Purnovate for the lease of three offices at 1180 Seminole Trail, Suite 495, Charlottesville, VA 22901. The sublease had a term of
two years, and the monthly rent was $1,400. On January 25, 2021, the Company acquired Purnovate as a wholly owned subsidiary. After the
acquisition, the Company directly or through Purnovate operates a chemistry and analytics laboratory in its 4,175 square feet leased laboratory
and office space (the “Facility”). On January 6, 2020, Purnovate entered a lease for the Facility with a term of three (3)
years. Included in the lease was the use of certain laboratory instrumentation and certain chemical assets. On January 19, 2021, Purnovate
entered an amendment to this lease extending the lease until January 31, 2026, committing us to total lease payments in the period from
January 1, 2022 and the end of the lease of $302,492.
Other company personnel work remotely.
Prior to the entry into our current sublease,
we occupied approximately 250 square feet of office space located at 1001 Research Park Blvd., Suite 100, Charlottesville, Virginia 22911.
This office service agreement has been terminated.
Item 1A. Risk Factors
Investing in our securities involves a high
degree of risk. In addition to the risks related to our business set forth in this Annual Report on Form 10-K and the other information
included and incorporated by reference in this Annual Report on Form 10-K, you should carefully consider the risks described below before
purchasing our securities. Additional risks, uncertainties and other factors not presently known to us or that we currently deem immaterial
may also impair our business operations.
Risks Relating to Our Company
We have incurred net losses every year and
quarter since our inception and anticipate that we will continue to incur net losses in the future.
We are a clinical stage biotechnology pharmaceutical
company that is focused on the discovery and development of medications for the treatment of addictions and related disorders of AUD in
patients with certain targeted genotypes. We have a limited operating history. Investment in biopharmaceutical product development is
highly speculative because it entails substantial upfront capital expenditures and significant risk that any potential product candidate
will fail to demonstrate adequate effect or an acceptable safety profile, gain regulatory approval and become commercially viable. We
have no products approved for commercial sale and have not generated any revenue from product sales to date, and we continue to incur
significant research and development and other expenses related to our ongoing operations. To date, we have not generated positive cash
flow from operations, revenues, or profitable operations, nor do we expect to in the foreseeable future. As of December 31, 2021, we had
an accumulated deficit of approximately $50.9 million.
Even if we succeed in commercializing our product
candidate or any future product candidates, we expect that the commercialization of our product will not begin until 2025 or later, we
will continue to incur substantial research and development and other expenditures to develop and market additional product candidates
and will continue to incur substantial losses and negative operating cash flow. We may encounter unforeseen expenses, difficulties, complications,
delays and other unknown factors that may adversely affect our business. 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 revenue. Our prior losses and expected future losses have had and will
continue to have an adverse effect on our shareholders’ equity and working capital.
We currently have no product revenues and
may not generate revenue at any time in the near future, if at all. Currently, we have no products approved for commercial sale.
We currently have no products for sale and we
cannot guarantee that we will ever have any drug products approved for sale. We and our product candidate are subject to extensive regulation
by the FDA, and comparable regulatory authorities in other countries governing, among other things, research, testing, clinical trials,
manufacturing, labeling, promotion, marketing, adverse event reporting and recordkeeping of our product candidates. Until, and unless,
we receive approval from the FDA or other regulatory authorities for our product candidates, we cannot commercialize product candidates
and will not have product revenues. Even if we successfully develop products, achieve regulatory approval, and then commercialize our
products, we may be unable to generate revenue for many years, if at all. We do not anticipate that we will generate revenue for at least
several years, if at all. If we are unable to generate revenue, we will not become profitable, and we may be unable to continue our operations.
For the foreseeable future, we will have to fund all of our operations from equity and debt offerings, cash on hand and grants. In addition,
changes may occur that would consume our available capital at a faster pace than expected, including changes in and progress of our development
activities, acquisitions of additional candidates and changes in regulation. Moreover, preclinical and clinical testing may not start
or be completed as we forecast and may not achieve the desired results. Therefore, we expect to seek additional sources of funding, such
as additional financing, grant funding or partner or collaborator funding, which additional sources of funding may not be available on
favorable terms, if at all.
We have had limited operations to date and
there can be no assurance that we will be able to execute on our business strategy.
We are a clinical stage company and have had limited
operations to date. We have yet to demonstrate our ability to overcome the risks frequently encountered in our industry and are still
subject to many of the risks common to such enterprises, including our ability to implement our business plan, market acceptance of our
proposed business and lead product, under-capitalization, cash shortages, limitations with respect to personnel, financing and other resources,
competition from better funded and experienced companies, and uncertainty of our ability to generate revenues. In fact, though individual
team members have experience running clinical trials, as a company we have yet to prove that we can successfully run a clinical trial
to the point of releasing data. There is no assurance that our activities will be successful or will result in any revenues or profit,
and the likelihood of our success must be considered in light of the stage of our development. In addition, no assurance can be given
that we will be able to consummate our business strategy and plans, or that financial, technological, market, or other limitations may
force us to modify, alter, significantly delay, or significantly impede the implementation of such plans. We have insufficient results
for investors to use to identify historical trends. Investors should consider our prospects in light of the risk, expenses and difficulties
we will encounter as an early stage company. Our revenue and income potential is unproven and our business model is continually evolving.
We are subject to the risks inherent to the operation of a new business enterprise, and cannot assure you that we will be able to successfully
address these risks.
We will need to secure additional financing
in order to support our operations and fund our current and future clinical trials. We can provide no assurances that any additional sources
of financing will be available to us on favorable terms, if at all. Our forecast of the period of time through which our current financial
resources will be adequate to support our operations and the costs to support our general and administrative, selling and marketing and
research and development activities are forward-looking statements and involve risks and uncertainties.
If we do not succeed in raising additional funds
on acceptable terms, we may be unable to complete planned product development activities or obtain approval of our product candidate from
the FDA and other regulatory authorities. We do not have any committed sources of capital other than our equity line with Keystone Capital
for which there can be no assurance that we will meet the use requirements. Moreover, if our future trial activities are significantly
delayed due to the coronavirus pandemic or the unrest in Eastern Europe, our project cost, including for planned Purnovate research and
development and operating overhead costs may significantly increase. In such case, we would need to obtain additional funding, either
through other grants or through potentially dilutive means. In any case, we will need to raise additional capital to complete our development
program and to meet our long-term business objectives.
While cash and cash equivalents at the date of
this annual report filing on form 10-K are expected to be sufficient to fund our operations for the next twelve months, given current
expectations, we will require additional financing as we continue to execute our business strategy. We will require additional funds in
order for additional Phase 3 trials of AD04, as well as any additional clinical trials or other development of any products we may acquire
or license, including those acquired from Purnovate. Our liquidity may be negatively impacted as a result of a research and development
cost increases in addition to general economic and industry factors. We anticipate that, to the extent that we require additional liquidity,
it will be funded through the incurrence of other indebtedness, additional equity financings or a combination of these potential sources
of liquidity. In addition, we may raise additional funds to finance future cash needs through grant funding and/or corporate collaboration
and licensing arrangements. If we raise additional funds by issuing equity securities or convertible debt, including pursuant to our Equity
Purchase Agreement with Keystone Capital, our stockholders will experience dilution. Debt financing, if available, would result in increased
fixed payment obligations and may involve agreements that include covenants limiting or restricting our ability to take specific actions,
such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration
and licensing arrangements with third parties, it may be necessary to relinquish valuable rights to our products, future revenue streams
or product candidates or to grant licenses on terms that may not be favorable to us. The covenants under future credit facilities may
limit our ability to obtain additional debt financing. We cannot be certain that additional funding will be available on acceptable terms,
or at all. Any failure to raise capital in the future could have a negative impact on our financial condition and our ability to pursue
our business strategies.
Additional financing, which is not in place at
this time, may be from the sale of equity or convertible or other debt securities in a public or private offering, from a credit facility
or strategic partnership coupled with an investment in us or a combination of both. Our ability to raise capital through the sale of equity
may be limited by the various rules of the Securities and Exchange Commission (the “SEC”) and The Nasdaq Capital Market (the
“Nasdaq”), which place limits on the number of shares of stock that may be sold. Equity issuances would have a dilutive effect
on our stockholders. We may be unable to raise sufficient additional financing on terms that are acceptable to us, if at all. Our failure
to raise additional capital and in sufficient amounts may significantly impact our ability to expand our business. For further discussion
of our liquidity requirements as they relate to our long-term plans, see the section entitled “Management’s Discussion and
Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”
We have identified material weaknesses in
our internal controls, and we cannot provide assurances that these weaknesses will be effectively remediated or that additional material
weaknesses will not occur in the future.
As a public company, we are subject to the reporting
requirements of the Exchange Act, and the Sarbanes-Oxley Act. We expect that the requirements of these rules and regulations will continue
to increase our legal, accounting and financial compliance costs, make some activities more difficult, time consuming and costly, and
place significant strain on our personnel, systems and resources.
The Sarbanes-Oxley Act requires, among other things,
that we maintain effective disclosure controls and procedures, and internal controls over financial reporting.
We do not yet have effective disclosure controls
and procedures, or internal controls over all aspects of our financial reporting. We are continuing to develop and refine our internal
controls over financial reporting . Our management is responsible for establishing and maintaining adequate internal control over our
financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. We will be required to expend time and resources to further
improve our internal controls over financial reporting, including by expanding our staff. However, we cannot assure you that our internal
control over financial reporting, as modified, will enable us to identify or avoid material weaknesses in the future.
We have identified material weaknesses in our internal control over
financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting
such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected
on a timely basis. The material weaknesses identified to date include (i) lack of formal risk assessment under COSO framework (ii) policies
and procedures which are not adequately documented, (iii) lack of proper approval processes, review processes and documentation for such
reviews, (iv) insufficient GAAP experience regarding complex transactions and ineffective review processes over period end financial disclosure
and reporting (v) deficiencies in the risk assessment, design and policies and procedures over information technology (“IT”)
general controls. and (iv) insufficient segregation of duties.
We will be required to expend time and resources
to further improve our internal controls over financial reporting, including by expanding our staff. However, we cannot assure you that
our internal control over financial reporting, as modified, will enable us to identify or avoid material weaknesses in the future.
Our current controls and any new controls that
we develop may become inadequate because of changes in conditions in our business, including increased complexity resulting from our international
expansion. Further, weaknesses in our disclosure controls or our internal control over financial reporting may be discovered in the future.
Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could harm
our operating results or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements
for prior periods. Any failure to implement and maintain effective internal control over financial reporting could also adversely affect
the results of management reports and independent registered public accounting firm audits of our internal control over financial reporting
that we will eventually be required to include in our periodic reports that will be filed with the SEC. Ineffective disclosure controls
and procedures, and internal control over financial reporting could also cause investors to lose confidence in our reported financial
and other information, which would likely have a negative effect on the market price of our common stock.
Our independent registered public accounting firm
is not required to audit the effectiveness of our internal control over financial reporting until after we are no longer an “emerging
growth company” as defined in the JOBS Act and meet other requirements. At such time, our independent registered public accounting
firm may issue a report that is adverse in the event it is not satisfied with the level at which our internal control over financial reporting
is documented, designed or operating. Any failure to maintain effective disclosure controls and internal control over financial reporting
could have a material and adverse effect on our business and operating results, and cause a decline in the market price of our common
stock.
We rely on a license to use various technologies
that are material to our business and if the agreement were to be terminated or if other rights that may be necessary or we deem advisable
for commercializing our intended products cannot be obtained, it would halt our ability to market our products and technology, as well
as have an immediate material adverse effect on our business, operating results and financial condition.
Our prospects are significantly dependent upon
the UVA LVG License. The UVA LVG License grants us exclusive, worldwide rights to certain existing patents and related intellectual property
that covers AD04, our lead and currently only product candidate. If we breach the terms of the UVA LVG License, including any failure
to make minimum royalty payments required thereunder or failure to reach certain developmental milestones and completion of deadlines,
including, submitting an NDA by December 31, 2024 and commencing commercialization of an FDA approved product by December 31, 2025, or
other factors, including but not limited to, the failure to comply with material terms of the Agreement, the licensor has the right to
terminate the license. If we were to lose or otherwise be unable to maintain this license on acceptable terms, or find that it is necessary
or appropriate to secure new licenses from other third parties, we would not be able to market our products and technology, which would
likely require us to cease our current operations which would have an immediate material adverse effect on our business, operating results
and financial condition.
Our business is dependent upon the success
of our lead product candidate, AD04, which requires significant additional clinical testing before we can seek regulatory approval and
potentially launch commercial sales.
Our business and future success depends upon our
ability to obtain regulatory approval of and then successfully commercialize our lead investigational product candidate, AD04 and other
product candidates. AD04 is in clinical stage development. To date, our main focus and the investment of a significant portion of our
efforts and financial resources has been in the development of our lead investigational product candidate, AD04, for which we are currently
completing the ONWARD Phase 3 clinical trial with 302 patients in Scandinavia and Central and Eastern Europe, which targets the reduction
of risk drinking (heavy drinking of alcohol) in subjects that possess selected genetics of the serotonin transporter and/or 5-HT3 receptor
gene. We expect that at least one additional Phase 3 clinical trial will be required for approval, as well as, one or more supportive
clinical studies Even though we are pursuing a registration pathway based on specific FDA input and guidance and the EMA precedents and
guidance, there are many uncertainties known and unknown that may affect the outcome of the trial. These include adequate patient enrollment,
adequate supply of our product candidate, potential changes in the regulatory landscape, and the results of the trial being successful.
All of our future product candidates, as well
as AD04, will require additional clinical and non-clinical development, regulatory review and approval in multiple jurisdictions, substantial
investment, access to sufficient commercial manufacturing capacity and significant marketing efforts before we can generate any revenue
from product sales. We expect AD04 will need at least two Phase 3 trials (including the ONWARD Phase 3 trial we are currently completing
in Scandinavia and Central and Eastern Europe) and one or more supportive clinical studies to gain approval in either the U.S. or Europe
for AUD and additional development activity, including, without limitation, clinical trials, in order to seek approval for the use of
AD04 to treat any other indications (e.g., such as opioid use disorder, gambling addiction, smoking cessation, and other drug addictions).
In addition, because AD04 is our most advanced product candidate and there is limited history information on long-term effects of our
proposed dosage, there is always a chance of developmental delays or regulatory issues or other problems arising, with our development
plans and depending on their magnitude, our business could be significantly harmed. In any case, the costs associated with completion
of our ONWARD Phase 3 trial, a second, confirmatory trial, commercialization of AD04, and the costs of developing AD04 for use in other
indications are significant, and will require obtaining funding, possibly through equity sales, before AD04 generates revenue.
Our future success depends heavily on our ability
to successfully manufacture, develop, obtain regulatory approval, and commercialize AD04, which may never occur. We currently generate
no revenues from our product candidate, and we may never be able to develop or commercialize a marketable drug.
The active ingredient of our product candidate,
ondansetron, is currently available in generic form.
Ondansetron, the active pharmaceutical ingredient
(“API”) of AD04, was granted FDA approval as Zofran® in January 1991 and is approved in many foreign markets.
Ondansetron is commercially available in generic form, but not available: (i) at the formulation/dosage levels expected to be marketed
by us, or (ii) with a requirement to use a diagnostic biomarker, as we expect to be the case with AD04. Although ondansetron has been
approved to treat nausea and emesis it has not been approved to treat AUD and it has not been approved for daily long-term use as planned
by us. Clinical testing to date of ondansetron at the higher doses used to treat nausea/emesis have not shown effectiveness in treating
AUD or any other addictive disorder; however, if a third party conducted a Phase 3 clinical program and showed success treating AUD at
those doses, we could not prevent such third party from marketing ondansetron for AUD at those doses.
Results from clinical studies suggest that high
intravenous doses of ondansetron may affect the electrical activity of the heart. In a Drug Safety Communication dated June 29, 2012,
the FDA stated that: “A 32 mg single intravenous dose of ondansetron (Zofran, ondansetron hydrochloride, and generics) may affect
the electrical activity of the heart (QT interval prolongation), which could pre-dispose patients to develop an abnormal and potentially
fatal heart rhythm known as Torsades de Pointes.” In addition: “No single intravenous dose should exceed 16 mg.” There
are also several recent lawsuits claiming that Zofran® used for the unapproved use of morning sickness causes birth defects.
Although we do not believe that our dosage will cause such adverse event there can be no assurance that the negative side effects of the
generic drug that have been found in higher dosages will not occur in our dosage or otherwise deter potential users of our product candidate
and adversely impact sales of our product candidate. If we were to be required to have such a warning on our drug label, patients may
be deterred from using our product candidates.
In addition, we also face the risk, that doctors
will prescribe off label, the generic form of ondansetron to treat AUD despite the different dosage of ondansetron in the generic form
from that in AD04, the lack of demonstrated clinical efficacy against AUD at the currently available doses (i.e., the Zofran ®
and approved generics), and the potential safety concerns if the currently available/higher doses are taken chronically as would be needed
for AUD or other addictions. Physicians, or their patients, could divide the lowest dose existing oral tablet into more than ten parts
to approximate the necessary AD04 dosage.
Although we believe that any attempt by competitors
to reformulate and market ondansetron at our intended dosage levels, while technically feasible, infringes on our intellectual property
rights, and should, accordingly, be actionable, we cannot give assurances that we would be successful in defending our rights or that
we will have access to sufficient funds necessary to successfully prosecute any such violations of, or infringements on, our intellectual
property rights. Additionally, we cannot ensure investors that other companies will not discover and seek to commercialize low doses of
ondansetron, not currently available, for other indications.
Coronavirus could adversely impact our business,
including our clinical trials.
In December 2019, a novel strain of coronavirus,
COVID-19, was reported to have surfaced in Wuhan, China. Since then, the COVID-19 coronavirus has spread to multiple countries, including
countries in Europe which we have planned or active clinical trial sites. As the COVID-19 coronavirus continues to spread around the globe,
we will likely experience disruptions that could severely impact our business and clinical trials, including:
|
● |
delays or difficulties in enrolling patients in our clinical trials; |
|
● |
delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff; |
|
● |
diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials; |
|
● |
interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others; |
|
● |
limitations in employee resources that would otherwise be focused on the conduct of our clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people; |
|
● |
delays in receiving approval from local regulatory authorities to initiate our planned clinical trials; |
|
● |
delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials; |
|
● |
interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product used in our clinical trials; |
|
● |
changes in local regulations as part of a response to the COVID-19 coronavirus outbreak which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether; |
|
● |
delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees; |
|
● |
delay in the timing of interactions with the FDA due to absenteeism by federal employees or by the diversion of their efforts and attention to approval of other therapeutics or other activities related to COVID-19; and |
|
● |
refusal of the FDA to accept data from clinical trials in affected geographies outside the United States. |
In addition, the outbreak of the coronavirus (“COVID-19”)
could continue to disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism
by members of management and other employees who elect not to come to work due to the illness affecting others in our office or laboratory
facilities, or due to quarantines. COVID-19 illness could also impact members of our Board of Directors resulting in absenteeism from
meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors
or its committees needed to conduct meetings for the management of our affairs.
The global outbreak of the COVID-19 coronavirus
continues to rapidly evolve. The extent to which the COVID-19 coronavirus may impact our business and clinical trials will depend on future
developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread and possible
resurgences of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries,
business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and
treat the disease.
Business disruptions
could seriously harm our future revenue and financial condition and increase costs and expenses.
Our operations and those of our third-party suppliers
and collaborators could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes or
other extreme weather conditions, medical epidemics, labor disputes, war or other business interruptions. Any interruption could seriously
harm our ability to timely proceed with any clinical programs or to supply product candidates for use in our clinical programs or during
commercialization. For example, the current COVID-19 pandemic has, at points, caused an interruption in our clinical trial activities.
Additionally, supply chains disruptions impact and may continue to impact our research activities. Moreover, at the end of 2021 and into
2022, tensions between the United States and Russia escalated when Russia amassed large numbers of military ground forces and support
personnel on the Ukraine-Russia border and, in February 2022, Russia invaded Ukraine. In response, North Atlantic Treaty Organization,
or NATO, has deployed additional military forces to Eastern Europe and the Biden administration announced certain sanctions against Russia.
The invasion of Ukraine and the retaliatory measures that have been taken, or could be taken in the future, by the United States, NATO,
and other countries have created global security concerns that could result in a regional conflict and otherwise have a lasting impact
on regional and global economies, any or all of which could disrupt our supply chain, and may adversely impact the cost and conduct of
our international clinical trials of our product candidates. For example, currently we have plans to conduct clinical trials in Eastern
European countries, and may be prevented from doing so. This could negatively impact the anticipated timing and completion of our clinical
trials and/or analyses of clinical results.
While there exists a large body of evidence
supporting the safety of our primary API, ondansetron, under short-term use, there are currently no long-term use clinical safety data
available.
We intend to market our products, particularly
AD04, for long-term use by patients seeking to reduce their number of days of heavy drinking, and we assume future sales volumes reflecting
such extended use.
Studies of Zofran ® conducted as
part of its FDA and other regulatory agencies review process found that the drug is well-tolerated and results in few adverse side effects
at dosages almost 100 times the dosage expected to be formulated in AD04. However, to the best of our knowledge, no comprehensive clinical
study has been performed to date that has evaluated the safety profile of ondansetron for long-term use. We expect the FDA will require
us to provide safety data in at least 100 patients for 12 months and can offer no assurances that safety results of these long term use
studies will lead to any subsequent approval for long-term use. There can be no assurance that long-term usage of ondansetron, at dosages
anticipated by us, will be safe. Though the FDA has stated it will not require additional non-clinical testing nor will it require a QT
interval prolongation clinical study, such statements by the FDA are not legally binding on the agency.
All of our current data for our lead product
candidate are the result of Phase 2 clinical trials conducted by third parties and do not necessarily provide sufficient evidence that
our products are viable as potential pharmaceutical products.
Through our proprietary access to relevant laboratory
and clinical trial results of the University of Virginia’s research program, and through our reliance on publicly available third-party
research, we possess toxicology, pharmacokinetic, and other preclinical data and clinical data on AD04. As of now, AD04 has completed
only Phase 2 clinical trials and we are now completing our first Phase 3 trial. There is no guarantee that Phase 2 results can or will
be replicated by pivotal Phase 3 studies.
To date, long-term safety and efficacy have not
yet been demonstrated in clinical trials for our investigational product candidate. Favorable results in early studies or trials may not
be repeated in later studies or trials. Even if our clinical trials are initiated and completed as planned, we cannot be certain that
the results will support our product candidate claims. Success in preclinical testing and early clinical trials does not ensure that later
clinical trials will be successful. We cannot be sure that the results of later clinical trials would replicate the results of prior clinical
trials and preclinical testing, nor that they would satisfy the requirements of the FDA or other regulatory agencies. Clinical trials
may fail to demonstrate that our product candidate is safe for humans and effective for indicated uses. Preclinical and clinical results
are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals or commercialization. Any
delay in, or termination of, our clinical trials would delay our obtaining FDA or EMA approval for the affected product candidate and,
ultimately, our ability to commercialize that product candidate.
Previous clinical trials using ondansetron have
had different trial designs, doses, parameters and endpoints than the current ONWARD Phase 3 clinical trial that is expected to serve
as a basis for approval of AD04. Though various doses of ondansetron have been tested as treatments for alcohol addiction (Johnson, BA
et al., 2011; Johnson, BA et al., 2000; Kranzler et al, 2003; Sellers, EM et al., 1994), the 283-patient Phase 2b clinical trial on which
we are largely basing our clinical expectations only tested one dosing regimen, which was weight-based (Johnson, BA et al., 2011). We
plan to use a fixed dose in future clinical trials that we believe provides good coverage given the dose ranges tested clinically; however,
it is possible that the dose selected will not be the optimal dose and so drug effects may be limited or not be demonstrated sufficiently
in clinical testing. Additionally, only one genotype in the genetic panel that will be used to define patients that are genotype positive
for treatment with AD04 was used in primary analyses of the Phase 2b trial and three of the genotypes were added to the panel after a
retrospective exploratory analysis of the Phase 2b data. The genotype in the panel related to the 5-HTT, that was included in the primary
analysis (Johnson, BA et al., 2011) appears to make up about half of the patients that are genotype positive. The three genotypes related
to modulation of the 5-HT3 receptor were selected based on a retrospective analysis that was constrained to 18 single-nucleotide polymorphism
(“SNPs”) identified for analysis (Johnson, BA et al., 2013). Therefore, confidence in the effects of the 5-HT3 genetics is
less than that for the 5-HTT genetics, and this could negatively impact the treatment effect of AD04 in Phase 3 trials for a segment of
the patients identified as genotype positive, which could dilute the overall demonstrated effect of AD04 in the trial.
The endpoints for the Phase 2b clinical trial
of AD04 were reduction in the severity of drinking, measured as drinks per day of drinking alcohol and reduction frequency of drinking,
measured by days of total abstinence from alcohol. These are surrogate endpoints for the endpoints expected to be required for approval,
which, for Europe, are expected to be reduction of heavy drinking days (defined herein), measured in percentage of heavy drinking days
per month, and total average alcohol consumed per month, and, for the United States, is expected to be the percentage of patients that
have no heavy drinking days in the final 2 months of a six month treatment regimen of AD04. Though the Phase 2b trial showed a statistically
significant effect against both pre-specified endpoints and when analyzed for reducing heavy drinking days, all when compared against
the placebo group, it is possible that AD04 could affect the endpoints of the Phase 2b trial while not demonstrating a strong enough effect
to gain approval.
The Phase 2b clinical trial was 12 weeks in duration,
including a one week placebo run-in period, and the Phase 3 trials expected to be required for approval will be 24 weeks. Though the effect
of AD04 against AUD in the Phase 2b trial appeared to begin in the first month of the trial and appeared durable throughout the trial,
we cannot be sure the effect will extend for the duration of the Phase 3 trials.
The FDA and/or EMA may not accept our planned
Phase 3 endpoints for final approval of AD04 and may determine additional clinical trials are required for approval of AD04.
The FDA has indicated to us that a comparison
of the percent of patients with no heavy drinking days in the last two months of a six month clinical trial between the drug and placebo
groups will be a satisfactory endpoint for determination of a successful Phase 3 trial of AD04 and has published the draft guidance Alcoholism:
Developing Drugs for Treatment Guidance for Industry dated February 2015 indicating this endpoint for the development of drugs for
AUD. Similarly, the EMA has in the past accepted the co-primary endpoints of reduction from baseline in days of heavy drinking and reduction
total grams of alcohol consumed per month and has published the Guideline on the development of medicinal products for the treatment
of alcohol dependence on February 18, 2010 stating these endpoints as approvable endpoints for alcohol addiction treatment. Despite
these indications, neither the FDA nor the EMA is bound to accept the stated endpoint if a new drug application for AD04 is submitted
and their definitions of a heavy drinking day may change. We, however, can offer no assurance that the FDA or EMA will approve our primary
endpoints, that we can achieve success at the any endpoints they do approve, or that these potential benefits will subsequently be realized.
We will incur additional costs and our approvals
could be delayed if the FDA or EMA requires additional clinical trials in patients that are negative for the genotypes targeted by AD04.
In addition, clinical trials conducted with only genotype positive subjects will likely result in labeling restricted to treating patients
that are genotype positive.
Although the FDA has indicated that it sees little
evidence of positive effects for the use of AD04 in subjects that are negative for the genotypes targeted by AD04 and has stated that
it would not object to the AD04 Phase 3 clinical trials going forward without including these additional subjects, the FDA has indicated
that some research in this area may be required prior to approval of AD04 for AUD within the marker negative population. We believe the
data supports our hypothesis that no further studies in genotype negative patients need be conducted. However, the FDA has indicated that
any approval based on a trial only in genotype positive subjects would result in labeling restricted to treating patients that are genotype
positive. If further studies are required, we will incur additional costs not anticipated, and it could delay approval of AD04 or, if
the results of such studies are not positive for AD04, it may result in AD04 not being approved or it may result in AD04’s patents
failing to protect AD04 against generic competition.
Under the Pediatric Research Equity Act (“PREA”),
NDAs or supplements to NDAs must contain data to assess the safety and effectiveness of the drug for the claimed indications in all relevant
pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the drug is safe and effective.
We plan to test AD04 in adolescent patients (ages 12-17) as part of our next Phase 3 trial. If successful, we intend to request labeling
for treating adolescent patients.
Our use of the currently manufactured clinical
trial material in the plan Phase 3 trial is dependent upon the review and approval of the relevant regulatory agencies and authorities.
The Company has manufactured additional clinical
trial material for use in the ONWARD trial and other studies that may be required by the FDA or EMA. No assurance can be given that the
CMC plan developed by us will be satisfactory to the regulatory agencies or that the clinical trial material produced for use in clinical
trials of AD04 will be approved for use in the trials, either of which could result in delay of the clinical trial program and a requirement
for increased investment prior to commencement of clinical trials.
Our lead investigational product, AD04,
is dependent on a successful development, approval, and commercialization of a genetic test, which is expected to be classified as a companion
diagnostic.
Treatment with AD04 will be dependent on identification of patients
with a genetic test (i.e., a companion diagnostic). Companion diagnostics and complementary diagnostics are regulated as medical devices
by the FDA and, as such, require either clearance or approval prior to commercialization. While the technology for the test we plan to
use is well established, it cannot be certain the testing laboratory we set up will be able to conduct the test with the selectivity and
sensitivity that will be required or that the genetic test will be approved by FDA for such use, which could increase the time and cost
to develop AD04 and possibly prevent marketing approval. While we have been party to a joint meeting with the Center for Drug Evaluation
and Research (“CDER”, the FDA division responsible for drug approvals) and the Center for Devices and Radiological Health
(“CDRH”, the FDA division responsible for device approvals, including genetic tests) at which agreement was reached as to
the development path for the genetic test, neither CDER nor CDRH is bound to accept our planned submission package even if the data is
positive. We expect to need approval of a PMA or a 510(k) from CDRH for the companion diagnostics to be used with the drug product. We
are collecting and storing additional blood samples from all patients enrolled in the ONWARD Phase 3 trial, and plan to do so for any
future trials that may be conducted, in the event of any difficulties, however, we cannot be certain we can overcome all of the technological,
logistical or regulatory hurdles related to the genetic testing, which include, without limitation, technical validation of the test (e.g.
specificity, sensitivity, reproducibility, robustness of methods), clinical validation acceptable to CDER and CDRH, all of which are needed
for approval of AD04 and its companion diagnostic genetic test. Failure in any of these areas could delay approval of AD04, increase the
cost necessary to achieve approval of AD04 or prevent approval of AD04.
If we obtain approval of AD04 and its genetic
test, we currently plan to distribute the genetic test as widely as possible to third party testing companies with limited attention to
capitalizing on the revenue potential of the genetic test itself in order to achieve wider availability of the genetic test to drive market
uptake of AD04. However, we cannot be sure that third party testing companies will be willing to provide the test, that reimbursement
for the test will be available to make such business profitable, or that taking a genetic test will be acceptable to patients or physicians.
Additionally, our plans may change so that we attempt to make the test a material business of our own. In this event, the availability
of the genetic test in the market could be reduced, limiting market uptake of AD04, the testing business could fail, and we could be in
a position where it never reaches profitability. As one of our products/services, the genetic test will be subject to all of the risks
stated elsewhere herein related to reimbursement of our products and failure to achieve adequate reimbursement could limit the potential
sales of both the genetic test and AD04, and there is no assurance that the diagnostic will be approved or authorized for marketing.
We have limited experience as a company
conducting clinical trials.
We are a clinical stage company and our success
is dependent upon our ability to obtain regulatory approval for and commercialization of our investigational products, and we have not
demonstrated an ability to perform the functions necessary for the approval or successful commercialization of any product candidates.
The successful commercialization of any product candidates may require us to perform a variety of functions, including:
|
● |
continuing to undertake preclinical development and successfully enroll patients in clinical trials; |
|
● |
participating in regulatory approval processes; |
|
● |
formulating and manufacturing products; and |
|
● |
conducting sales and marketing activities. |
We have limited experience conducting and enrolling
patients in clinical trials. While certain members of our management and staff have significant experience in conducting clinical trials,
to date, we have not successfully completed any clinical trials to the point of releasing data. Until recently, our operations have been
limited primarily to organizing and staffing our company, acquiring, developing and securing our proprietary technology and conducting
our Phase 3 trial of AD04 and preclinical trials of our Purnovate assets. These operations provide a limited basis to assess our ability
to develop and commercialize our product candidate and the advisability of investing in our securities.
All of the preclinical and clinical trials relating
to our product candidate have been conducted by third parties. Although we have recruited a team that has significant experience with
managing clinical trials, we have no experience as a company in conducting our own clinical trials. In part because of this lack of experience,
we cannot guarantee that planned clinical trials will be completed on time, if at all. Large-scale trials require significant additional
financial and management resources, monitoring and oversight, and reliance on third-party clinical investigators, contract research organizations
(“CROs”), or consultants. Relying on third-party clinical investigators, CROs and manufacturers, which are all also subject
to governmental oversight and regulations, may also cause us to encounter delays that are outside of our control.
Our product candidate will require extensive
clinical and other testing.
Our product candidate will require extensive clinical
and other testing. Although our lead product candidate has completed a 283-patient Phase 2b clinical trial and is completing its first
Phase 3 clinical trial, we anticipate that we will be required to complete a second Phase 3 clinical trial in order to obtain regulatory
approval and therefore cannot predict with any certainty if or when we might submit an application for regulatory approval for any of
our product candidates or whether any such application will be accepted for review by the FDA or EMA, or whether any application will
be approved upon review.
Even if our clinical trials are completed as planned,
we cannot be certain that their results will support our proposed indications. Success in preclinical testing and early clinical trials
does not ensure that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will replicate
the results of prior clinical trials and preclinical testing. Results from earlier clinical trials may not be repeated in later clinical
trials. The clinical trial process may fail to demonstrate that our product candidate is safe and effective for their proposed uses. This
failure could cause us to abandon our product candidate and may delay development of other product candidates. Any delay in, or termination
of, our clinical trials will delay and possibly preclude the filing of any NDAs with the FDA or EMA and, ultimately, our ability to commercialize
our product candidate and generate product revenues.
Our clinical trials may fail to demonstrate
adequately the safety and efficacy of AD04 or any future product candidates, which would likely prevent or delay regulatory approval and
commercialization.
Before obtaining regulatory approvals for the
commercial sale of AD04 or any future product candidates, including AD04, we must demonstrate through lengthy, complex and expensive preclinical
testing and clinical trials that product candidates are both safe and effective for use in each target indication. Clinical testing is
expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical
trial process. The results of preclinical studies and early clinical trials of product candidates may not be predictive of the results
of later-stage clinical trials. Results from subsequent clinical trials may not be the same as the results from the Phase 2b clinical
trial that was conducted by the University of Virginia. There is typically an extremely high rate of attrition from the failure of product
candidates proceeding through clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety
and efficacy profile despite having progressed through preclinical studies and initial clinical trials. A number of companies in the biopharmaceutical
industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable safety issues, notwithstanding
promising results in earlier trials. We can make no assurances that, should our Phase 3 studies provide statistically significant and
clinical meaningful results evidencing that treatment with AD04 results in reduced days of heavy drinking or abstinence, these same results
will also provide evidence of greater patient efficacy rates and or patient benefit ratios vis-à-vis currently marketed drug treatments.
Most product candidates that commence clinical trials are never approved as products.
In addition, even if the trials are successfully
completed, we cannot guarantee that the FDA or foreign regulatory authorities will interpret the results as we do, and more trials could
be required before we submit product candidates for approval. To the extent that the results of the trials are not satisfactory to the
FDA or foreign regulatory authorities for support of a marketing application, approval of product candidates may be significantly delayed,
or we may be required to expend significant additional resources, which may not be available to us, to conduct additional trials in support
of potential approval of product candidates.
If we experience delays in the enrollment
of patients in our clinical trials our receipt of necessary regulatory approvals could be delayed or prevented.
Although we expect to complete our landmark ONWARD
pivotal Phase 3 clinical trial in the second quarter of 2022, we anticipate that we will be required to complete a second Phase 3 clinical
trial in order to obtain regulatory approval and therefore our inability to locate and continue to enroll a sufficient number of eligible
patients in any future clinical trials would result in significant delays or may require us to abandon one or more clinical trials. Retention
of subjects in clinical trials related to AUD can be challenging relative to trials in some other indications due to the nature of the
target population. In addition, COVID-19 has made trial operation, including, without limitation, patient enrollment, more difficult
and more difficult to project. In addition, since we expect that many of our future clinical trial sites will again be located in Eastern
Europe, our ability to enroll patients may be adversely impacted by the turmoil in Eastern Europe. Our ability to enroll patients in
trials is affected by many factors out of our control including the size and nature of the patient population, the proximity of patients
to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, the prevalence and successful recruiting
of patients that are genotype positive, competing clinical trials, and clinicians’ and patients’ perceptions as to the potential
advantages of the drug being studied in relation to other available therapies, including any new drugs that may be approved for the indications
we are investigating. Due to the use of a biomarker to determine enrollment in our current and planned Phase 3 clinical trials, we will
have a limited population of patients to draw from for our Phase 3 clinical trials.
Global health crises may adversely affect
our planned operations.
The conduct of anticipated second ONWARD Phase
3 trial could be materially and adversely affected by the risks, or the public perception of the risks, related to a pandemic or other
health crisis, such as the recent outbreak of novel coronavirus (COVID-19). A significant outbreak of contagious diseases in the human
population could result in a widespread health crisis that could adversely affect our ongoing trial. Such events could result in the complete
or partial closure of one or more of our critical vendors. In addition, an outbreak near our clinical trial site locations would likely
impact our ability to recruit patients, delay our clinical trials, and could affect our ability to complete our clinical trials within
the planned time periods. Also, public health authorities in the jurisdictions in which our trial is taking place may take steps that
would result in significant delay in our trial activities.
Our success will be dependent upon adoption
by physicians and others.
Even if the FDA and/or EMA approves our product
candidate or any future product candidates we may develop or acquire, the product will require acceptance among physicians, healthcare
payers, patients, and the medical community. Our products are to be used in combination with a genetic test targeted at patients with
certain specified genotypes. It is anticipated that physicians will recommend patients for screening prior to administration of AD04 or
future product candidates. Therefore, our business will be substantially dependent upon our ability to communicate with and obtain support
from physicians regarding the benefits of our products relative to alternative treatments available at that time.
Rapid technological change and substantial
competition may impair the business.
The pharmaceutical industry is subject to rapid
and substantial technological change. Technological competition in the industry from pharmaceutical and biotechnology companies, universities,
governmental entities, and others diversifying into the field is intense and is expected to increase. Many of these entities have significantly
greater research and development capabilities, as well as substantially more marketing, financial, and managerial resources than we do,
and represent significant competition. Acquisitions of, or investments in, competing biotechnology companies by large pharmaceutical companies
could increase these competitors’ financial, marketing, and other resources. We cannot assure you that developments by others will
not render our products or technologies noncompetitive or that we will be able to keep pace with technological developments. Competitors
have developed, or are in the process of developing, technologies that are, or in the future may be, the basis for competitive products.
Some of these products may have an entirely different approach or means of accomplishing similar therapeutic endpoints than products we
are currently developing. These competing products may be more effective and less costly than the products that we are developing. In
addition, conventional behavioral therapies and other treatment approaches currently in use today may continue to be used instead of,
rather than in conjunction with, our products.
Any product that we successfully develop, and
for which we gain regulatory approval, must compete for market acceptance and market share. Accordingly, important competitive factors,
in addition to completion of clinical testing and the receipt of regulatory approval, will include product efficacy, safety, timing, and
scope of regulatory approvals, availability of supply, marketing and sales capability, reimbursement coverage, pricing, and patent protection.
Existing or future competing products may provide greater therapeutic convenience or clinical or other benefits for a specific indication
than our products, or may offer comparable performance at a lower cost. If our products fail to capture and maintain market share, we
may not achieve sufficient product revenues and our business will suffer.
We will compete against fully integrated pharmaceutical
companies such as Alkermes and Indivior and smaller companies that are collaborating with larger pharmaceutical companies, academic institutions,
government agencies and other public and private research organizations. Many of these competitors have drugs already approved or in
development. In addition, many of these competitors, either alone or together with their collaborative partners, operate larger research
and development programs or have substantially greater financial resources than we do, as well as significantly greater experience in:
|
● |
developing drugs, and other therapies; |
|
● |
undertaking preclinical testing and clinical trials; |
|
● |
obtaining FDA and other regulatory approvals of drugs, biologics and other therapies; |
|
● |
formulating and manufacturing drugs, biologics and other therapies; and |
|
● |
launching, marketing and selling drugs, and other therapies. |
Risks Relating to Purnovate
The combined company may not experience
the anticipated strategic benefits of the Acquisition.
We believe the acquisition of Purnovate will provide
certain strategic benefits which would enable Adial to enhance its business and accelerate its business plan through an increased access
to capital in the public equity markets. The market price of our common stock may decline as a result of the acquisition if the combined
company does not achieve the perceived benefits of the Acquisition as rapidly or to the extent anticipated by us or Purnovate or investors,
financial or industry analysts. There can be no assurance that these anticipated benefits of the Acquisition will materialize or that
if they materialize will result in increased stockholder value or revenue stream to the combined company.
We may be unable to successfully integrate
the Purnovate businesses with its current management and structure.
Our failure to successfully complete the integration
of Purnovate could have an adverse effect on our prospects, business activities, cash flow, financial condition, results of operations
and stock price. Integration challenges may include the following:
|
● |
assimilating Purnovate’s technology and retaining personnel; |
|
● |
estimating the capital, personnel and equipment required for Purnovate based on the historical experience of management with the businesses they are familiar with; |
|
● |
minimizing potential adverse effects on existing business relationships; and |
|
● |
successfully developing the new products and services. |
Purnovate has had limited operations to date.
Purnovate is a start-up entity and has had limited
operations to date. As a start-up entity, Purnovate is subject to many of the risks common to such enterprises, including its ability
to implement its business plan, market acceptance of its proposed business and products, under-capitalization, cash shortages, limitations
with respect to personnel, financing and other resources, competition from better funded and experienced companies, and uncertainty of
its ability to generate revenues. There is no assurance that its activities will be successful or will result in any revenues or profit,
and the likelihood of its success must be considered in light of the stage of its development. Even if it generates revenue, there can
be no assurance that it will be profitable. In addition, no assurance can be given that it will be able to consummate its business strategy
and plans, as described herein, or that financial, technological, market, or other limitations may force it to modify, alter, significantly
delay, or significantly impede the implementation of such plans. Purnovate has insufficient results for investors to use to identify historical
trends or even to make quarter-to-quarter comparisons of its operating results. Purnovate’s revenue and income potential is unproven
and its business model is continually evolving. Purnovate is subject to the risks inherent to the operation of a new business enterprise,
and there can be no assurance that Purnovate will be able to successfully address these risks.
Purnovate has a limited operating history upon which to evaluate
its ability to commercialize its products.
Purnovate is a development-stage company and its
success is dependent upon its ability to develop and commercialize its products and it has not demonstrated an ability to perform the
functions necessary for the successful development and commercialization of any product candidates. The successful commercialization of
any product candidates will require Purnovate to perform a variety of functions, including:
|
● |
continuing to undertake preclinical development trials and initiating clinical trials; |
|
● |
participating in regulatory approval processes and obtaining regulatory approvals; |
|
● |
formulating and manufacturing products; and |
|
● |
conducting sales and marketing activities. |
Purnovate’s operations have been limited
to organizing and staffing Purnovate, acquiring, developing and securing its proprietary technology and undertaking preclinical studies
of its product candidates. Purnovate has yet to engage in any clinical trials and therefore the safety of its product candidates is uncertain.
Purnovate’s product candidates are
in early stages of clinical trials.
Because Purnovate’s product candidates are
in early stages of development they will require extensive preclinical and clinical testing. Purnovate’s lead product has not yet
entered clinical trials and cost, speed and ability to advance through clinical trials is uncertain. Purnovate cannot predict with any
certainty if or when it might submit an application for regulatory approval for any of its product candidates or whether any such application
will be accepted.
Purnovate’s technology may not result
in any successful drug candidates.
Purnovate has developed what it believes are
lead compounds that could be drug candidates. However, despite there being significant literature and in vitro and in
vivo evidence that adenosine analogs may be effective in treating a number of diseases and disorders, the compounds developed
to date have not been extensively tested in vitro and have not been tested in vivo. It is possible that any
and all compounds or product candidates developed by Purnovate or using its technology may fail or be determined not valuable to pursue
as products for a number of reasons, including, without limitation, due to toxicity, lack of efficacy, lack of stability, poor manufacturing
characteristics or otherwise.
There is uncertainty as to market acceptance
of Purnovate’s technology and products.
Purnovate has conducted its own research into
the markets for its products; however, because it will be a new entrant into the market, it cannot guarantee market acceptance of its
products and has somewhat limited information on which to estimate anticipated level of sales. Purnovate’s products will require
patients and doctors to adopt its technology. Purnovate’s industry is susceptible to rapid technological developments and there
can be no assurance that it will be able to match any new technological advances. If it is unable to match the technological changes in
the needs of its customers the demand for its products will be reduced.
Risks Relating to Our Business and Industry
If we do not obtain the necessary regulatory
approvals in the United States and/or other countries, we will not be able to sell our product candidates.
We cannot assure you that we will receive the
approvals necessary to commercialize AD04 or any future product candidates we acquire or develop in the future. We will need FDA approval
to commercialize our product candidates in the United States and approvals from the FDA-equivalent regulatory authorities in foreign jurisdictions
to commercialize our product candidates in those jurisdictions. In order to obtain FDA approval of any product candidate, we must submit
to the FDA an NDA, demonstrating that the product candidate is safe, pure and potent, and effective for its intended use. This demonstration
requires significant research including preclinical studies, as well as clinical trials. Satisfaction of the FDA’s regulatory requirements
typically takes many years, depends upon the type, complexity and novelty of the product candidate and requires substantial resources
for research, development and testing. We cannot predict whether our clinical trials will demonstrate the safety and efficacy of our product
candidates or if the results of any clinical trials will be sufficient to advance to the next phase of development or for approval from
the FDA. We also cannot predict whether our research and clinical approaches will result in drugs or therapeutics that the FDA considers
safe and effective for the proposed indications. The FDA has substantial discretion in the approval process.
The approval process may be delayed by changes
in government regulation, future legislation or administrative action, or changes in FDA policy that occur prior to or during our regulatory
review. Factors that might lead to a suspension or termination of a clinical trial include, but are not limited to:
|
● |
failure to conduct the clinical trial in accordance with U.S., international and or local regulatory requirements; |
|
● |
failure of medical investigators to follow clinical trial protocols; |
|
● |
unforeseen safety issues; and/or |
|
● |
lack
of adequate funding to continue any clinical trial. |
Further, delays in obtaining regulatory approvals
may:
|
● |
prevent or delay commercialization of, and our ability to derive product revenues from, product candidates; and |
|
● |
diminish any competitive advantages that we may otherwise believe that we hold. |
Even if we comply with all FDA requests, the FDA
may ultimately reject one or more of our applications. We may never obtain regulatory clearance for any product candidates. Failure to
obtain FDA approval of any of product candidates will severely undermine our business by leaving us without a saleable product, and therefore
without any source of revenues, until another product candidate can be developed. There is no guarantee that we will ever be able to develop
or acquire another product candidate.
In addition, the FDA may require us to conduct
additional preclinical and clinical testing or to perform post-marketing studies, as a condition to granting marketing approval of a product.
Initial acceptance by the FDA of clinical trial protocols is subject to constant review and any process control failures could result
in additional required testing. Regulatory approval of products often requires that subjects in clinical trials be followed for long periods
to assess their overall survival. The results generated after approval could result in loss of marketing approval, changes in product
labeling, and/or new or increased concerns about the side effects or efficacy of a product. The FDA has significant post-market authority,
including the explicit authority to require post-market studies and clinical trials, labeling changes based on new safety information,
and compliance with FDA-approved risk evaluation and mitigation strategies. The FDA’s exercise of its authority has in some cases
resulted, and in the future could result, in delays or increased costs during product development, clinical trials and regulatory review,
increased costs to comply with additional post-approval regulatory requirements and potential restrictions on sales of approved products
based on labeling or other requirements.
In foreign jurisdictions, we must also receive
approval from the appropriate regulatory authorities before we can commercialize any candidate products. Foreign regulatory approval processes
generally include all of the risks associated with the FDA approval procedures described above. There can be no assurance that we will
receive the approvals necessary to commercialize our product candidate for sale outside the United States.
Changes in regulatory requirements and guidance
may occur, and we may need to amend clinical trial protocols or our development plan to reflect these changes. Amendments may require
resubmitting clinical trial protocols to FDA and institutional review boards for reexamination, which may impact the costs, timing or
successful completion of a clinical trial. If we experience delays in completion of, or if we terminate any clinical trials, the commercial
prospects for product candidates may be harmed, and the ability to generate product revenues will be 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 product candidates.
Obtaining and maintaining regulatory approval
of product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of product candidates
in other jurisdictions.
Obtaining and maintaining regulatory approval
of product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other
jurisdiction, and a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory
approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities
in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval
procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those
in the United States, including additional preclinical studies or clinical trials, as clinical studies conducted in one jurisdiction may
not be accepted by or sufficient for regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a
product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price
that we intend to charge for our candidate products is also subject to approval. Additionally, some foreign jurisdictions require participation
of subjects from their country in the Phase 3 trials in order to gain approval in their country.
We intend to also submit marketing applications
in other jurisdictions, including European countries. Regulatory authorities in jurisdictions outside of the United States have requirements
for approval of product candidates with which we must comply prior to marketing in those jurisdictions. Obtaining foreign regulatory approvals
and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay
or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international
markets and/or fail to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market
potential of AD04 or any future product candidates will be harmed.
Even if we receive regulatory approval of AD04
or any future product candidates, we will be subject to ongoing regulatory obligations, such as post market surveillance and current good
manufacturing practice (“GMP”) requirements, and continued regulatory review, which may result in significant additional expense.
We may also be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with product
candidates. In addition, third parties on whom we rely must comply with regulatory requirements, and any non-compliance on their part
may negatively impact our business, assuming we obtain regulatory authorization at all.
Any regulatory approvals that we receive for product
candidates will require surveillance to monitor the safety and efficacy of the product candidate. The FDA may also require a Risk Evaluation
and Mitigation Strategy (“REMS”) program in order to approve product candidates, which could entail requirements for a medication
guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries
and other risk minimization tools. The FDA could also require a boxed warning, sometimes referred to as a Black Box Warning on the product
label to identify a particular safety risk, which could affect commercial efforts to promote and sell the product. In addition, if the
FDA or a comparable foreign regulatory authority approves product candidates, the manufacturing processes, labeling, packaging, distribution,
adverse event reporting, storage, advertising, promotion, import, export and recordkeeping for product candidates will be subject to extensive
and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports,
registration, as well as continued compliance with current GMPs and current good clinical practices (“GCPs”) for any clinical
trials that we conduct post-approval. We are also subject to certain user fees imposed by the regulatory agencies. Later discovery of
previously unknown problems with product candidates, including adverse events of unanticipated severity or frequency, or with our third-party
manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:
|
● |
restrictions on the marketing or manufacturing of product candidates, withdrawal of the product from the market, or product recalls; |
|
● |
fines, warning letters or holds on clinical trials; |
|
● |
refusal by the FDA to approve pending applications or supplements to approved applications filed by us or suspension or revocation of approvals; |
|
● |
product seizure or detention, or refusal to permit the import or export of product candidates; and |
|

injunctions or the imposition of civil or criminal penalties. |
The FDA’s and other regulatory authorities’
policies may change, such as those required by the 21st Century Cures Act, and additional government regulations may be enacted
that could prevent, limit or delay regulatory approval of AD04 or any future product candidates. In addition, it is unclear what changes,
if any, the new presidential administration may bring. We cannot predict the likelihood, nature or extent of government regulation that
may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to
changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance,
we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.
Clinical trials are very expensive, time-consuming
and difficult to design and implement.
As part of the regulatory process, we must conduct
clinical trials for each product candidate to demonstrate safety and efficacy to the satisfaction of the FDA and other regulatory authorities.
As we advance AD04 or any future product candidates we expect that our expenses will increase. The number and design of the clinical trials
that will be required varies depending upon product candidate, the condition being evaluated, current medical strategies and the trial
results themselves. Therefore, it is difficult to accurately estimate the cost of the clinical trials. Clinical trials are very expensive
and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process
is also time consuming. We estimate that clinical trials of product candidates including AD04, will take at least several years to complete.
Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to abandon or repeat clinical
trials. The commencement and completion of clinical trials may be delayed or prevented by several factors, including:
|
● |
unforeseen safety issues; |
|
● |
failure to determine appropriate dosing; |
|
● |
greater than anticipated cost of our clinical trials; |
|
● |
failure to demonstrate effectiveness during clinical trials; |
|
● |
slower than expected rates of subject recruitment or difficulty obtaining investigators; |
|
● |
subject drop-out or discontinuation; |
|
● |
inability to monitor subjects adequately during or after treatment; |
|
● |
third party contractors, including, without limitation, CRO’s and manufacturers, failing to comply with regulatory requirements or meet their contractual obligations to us in a timely manner; |
|
● |
reaching agreements with prospective CROs, and trial sites, both of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites; |
|
● |
insufficient or inadequate supply or quality of product candidates or other necessary materials to conduct our trials; |
|
● |
potential additional safety monitoring, or other conditions required by FDA or comparable foreign regulatory authorities regarding the scope or design of our clinical trials, or other studies requested by regulatory agencies; |
|
● |
problems engaging Institutional Review Boards (“IRBs”), to oversee trials or in obtaining and maintaining IRB approval of studies; |
|
● |
imposition of clinical hold or suspension of our clinical trials by regulatory authorities; and |
|
● |
inability or unwillingness of medical investigators to follow our clinical protocols. |
In addition, we or the FDA may suspend or terminate
our clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or if the FDA finds deficiencies
in our Investigational New Drug, or IND, submissions or the conduct of these trials. Therefore, we cannot predict with any certainty when,
if ever, future clinical trials will commence or be completed.
AD04 and any future product candidates may
cause undesirable side effects or have other properties that could halt their clinical development, prevent their regulatory approval,
limit their commercial potential or result in significant negative consequences.
Undesirable side effects caused by AD04 or any
future product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more
restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign regulatory authorities. Results
of our trials could reveal a high and unacceptable severity and prevalence of side effects or other unexpected characteristics.
If unacceptable safety concerns or other adverse
events arise in the development of a product candidate, our clinical trials could be suspended or terminated or the FDA or comparable
foreign regulatory authorities could order us to cease clinical trials or deny approval of such product candidate for any or all targeted
indications. Treatment-related side effects could also affect patient recruitment or the ability of enrolled subjects to complete the
trial or result in potential product liability claims. Inadequate training in recognizing or managing the potential side effects of a
product candidate could result in patient deaths. Any of these occurrences may harm our business, financial condition and prospects significantly.
We may incur substantial liabilities and
may be required to limit commercialization of our products in response to product liability lawsuits.
The testing and marketing of drug product candidates
entail an inherent risk of product liability. Product liability claims might be brought against us by consumers, health care providers
or others selling or otherwise coming into contact with our products. Clinical trial liability claims may be filed against us for damages
suffered by clinical trial subjects or their families. If we cannot successfully defend ourselves against product liability claims, we
may incur substantial liabilities or be required to limit commercialization of our products which could impact our ability to continue
as a going concern. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential
product liability claims could prevent or inhibit the commercialization of pharmaceutical products we develop, alone or with collaborators.
In addition, regardless of merit or eventual outcome, product liability claims may result in:
|
● |
decreased demand for any approved product candidates; |
|
● |
impairment of our business reputation; |
|
● |
withdrawal of clinical trial participants; |
|
● |
costs of related litigation;
|
|
● |
distraction of management’s attention; |
|
● |
substantial monetary awards to patients or other claimants; |
|
● |
the inability to successfully commercialize any approved drug candidates. |
There is uncertainty as to market acceptance
of our technology and product candidates.
Even if the FDA approves our current product
candidate, or any future product candidates we may develop or acquire, the products may not gain broad market acceptance among physicians,
healthcare payers, patients, and the medical community. We have conducted our own research into the markets for our product candidates;
however, we cannot guarantee market acceptance of our product candidates, if approved, and have somewhat limited information on which
to estimate our anticipated level of sales. Product candidates, if approved, will require patients, healthcare providers and doctors
to adopt our technology. Our industry is susceptible to rapid technological developments and there can be no assurance that we will be
able to match any new technological advances. If we are unable to match the technological changes in the needs of our customers, the
demand for our products will be reduced. Acceptance and use of any products we market, assuming market authorization approval at all,
will depend upon a number of factors including:
|
● |
perceptions by members of the health care community, including physicians, about the safety and effectiveness of our products; |
|
● |
limitation on use or warnings required by FDA in our product labeling; |
|
● |
cost-effectiveness of our products relative to competing products; |
|
● |
convenience and ease of administration; |
|
● |
potential advantages of alternative treatment methods; |
|
● |
availability of reimbursement for our products from government or other healthcare payers; and |
|
● |
effectiveness of marketing and distribution efforts by us and our licensees and distributors, if any. |
Because we expect virtually all of our product
revenues for the foreseeable future to be generated from sales of AD04, if approved, the failure of this product to find market acceptance
would substantially harm our business and would adversely affect our revenue.
Even if we are able to obtain regulatory
approval for our product candidate or any product candidates we develop or acquire, we will continue to be subject to ongoing and extensive
regulatory requirements, and our failure, or the failure of our contract manufacturers, to comply with these requirements could substantially
harm our business.
If the FDA approves our product candidate or any
product candidates we develop or acquire, the labeling, manufacturing, packaging, adverse events reporting, storage, advertising, promotion
and record-keeping for our products will be subject to ongoing FDA requirements and continued regulatory oversight and review. We may
also be subject to additional FDA post-marketing obligations. If we are not able to maintain regulatory compliance, we may not be permitted
to market product candidates and/or may be subject to product recalls or seizures. The subsequent discovery of previously unknown problems
with any marketed product, including adverse events of unanticipated severity or frequency, may result in restrictions on the marketing
of the product, and could include withdrawal of the product from the market.
Our employees, independent contractors,
consultants, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory
standards and requirements.
We are exposed to the risk of employee fraud or
other illegal activity by our employees, independent contractors, consultants, commercial partners and vendors. Misconduct by these parties
could include intentional, reckless and/or negligent conduct that fails to: (i) comply with the laws of the FDA and other similar foreign
regulatory bodies; (ii) provide true, complete and accurate information to the FDA and other similar foreign regulatory bodies; (iii)
comply with manufacturing standards we have established; (iv) comply with healthcare fraud and abuse laws in the United States and similar
foreign fraudulent misconduct laws; or (v) report financial information or data accurately or to disclose unauthorized activities to us.
Any such misconduct or noncompliance could negatively affect the FDA’s review of our regulatory submission, including delaying approval
or disallowance of certain information to support the submission, and/or delay a federal or state healthcare program’s or a commercial
insurer’s determination regarding the availability of future reimbursement for product candidates. If we obtain FDA approval of
any product candidates and begin commercializing those products in the United States, our potential exposure under such laws will increase
significantly, and our costs associated with compliance with such laws are also likely to increase. These laws may impact, among other
things, our current activities with principal investigators and research patients, as well as proposed and future sales, marketing and
education programs. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements
in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices.
These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s),
certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper
use of information obtained in the course of patient recruitment for clinical trials. The laws that may affect our ability to operate
or may require us to modify certain programs include, but are not limited to:
|
● |
the federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an individual, or the purchase, lease, order or recommendation of any good, facility, item or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs; |
|
● |
federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment or approval from Medicare, Medicaid, or other third-party payors (both governmental and private) that are false or fraudulent or knowingly making a false statement to improperly avoid, decrease or conceal an obligation to pay money to a federal or state healthcare program or private payor; |
|
● |
the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which, among other things, created new federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters; |
|
● |
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (“HITECH”), and their respective implementing regulations, which, among other things, impose requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses as well as their respective business associates that perform services for them that involve the use, or disclosure of, individually identifiable health information, relating to the privacy, security and transmission of such individually identifiable health information; |
|
● |
the federal Physician Payment Sunshine Act, created under the Healthcare Reform Act (as defined herein), and its implementing regulations, which require certain manufacturers of drugs, devices, biologicals and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to the United States Department of Health and Human Services (“HHS”), information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; |
|
● |
federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers; and |
|
● |
the Foreign Corrupt Practices Act (the “FCPA”) and similar antibribery and anticorruption laws in other countries that, for example, prevent improper payments or transfers of anything of value to foreign officials for the purpose of gaining commercial advantage, obtaining or retaining business, or to enhancing clinical trials. |
Additionally, we are subject to state and foreign
equivalents of each of the healthcare laws described above, among others, some of which may be broader in scope and may apply regardless
of the payor.
It is not always possible to identify and deter
employee misconduct, and the precautions we take to detect and prevent inappropriate conduct may not be effective in controlling unknown
or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure
to be in compliance with such laws or regulations. Efforts to ensure that our business arrangements will comply with applicable healthcare
laws may involve substantial costs. It is possible that governmental and enforcement authorities will conclude that our business practices
may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws
and regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights,
those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties,
damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs,
contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could
adversely affect our ability to operate our business and our results of operations. In addition, the approval and commercialization of
any product candidates outside the United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above,
among other foreign laws.
We have no experience selling, marketing
or distributing products and have no internal capability to do so.
We currently have no sales, marketing or distribution
capabilities, including, without limitation, capabilities to market AD04 or its companion genetic test. We do not anticipate having the
resources in the foreseeable future to allocate to the sales and marketing of our proposed products, if approved. Our future success depends,
in part, on our ability to enter into and maintain collaborative relationships for such capabilities, the collaborator’s strategic
interest in the products under development and such collaborator’s ability to successfully market and sell any such products. We
intend to pursue collaborative arrangements regarding the sales and marketing of our products, however, there can be no assurance that
we will be able to establish or maintain such collaborative arrangements, or if able to do so, that our collaborators will have effective
sales forces. To the extent that we decide not to, or are unable to, enter into collaborative arrangements with respect to the sales and
marketing of our proposed products, significant capital expenditures, management resources and time will be required to establish and
develop an in-house marketing and sales force with technical expertise. There can also be no assurance that we will be able to establish
or maintain relationships with third party collaborators or develop in-house sales and distribution capabilities. To the extent that we
depend on third parties for marketing and distribution, any revenues we receive will depend upon the efforts of such third parties over
whom we have no control, and there can be no assurance that such efforts will be successful. In addition, there can also be no assurance
that we will be able to successfully market and sell our products in the United States or overseas on our own.
We may not be successful in establishing
and maintaining strategic partnerships, which could adversely affect our ability to develop and commercialize products.
We may seek to enter into strategic partnerships
in the future, including alliances with other biotechnology or pharmaceutical companies, to enhance and accelerate the development and
commercialization of our products, such as a third party drug development company. We face significant competition in seeking appropriate
strategic partners and the negotiation process is time-consuming and complex and can be costly. Moreover, we may not be successful in
our efforts to establish a strategic partnership or other alternative arrangements for any future product candidates and programs because
our research and development pipeline may be insufficient, our product candidates and programs may be deemed to be at too early of a stage
of development for collaborative effort and/or third parties may not view our product candidates and programs as having the requisite
potential to demonstrate safety and efficacy or return on investment. Even if we are successful in our efforts to establish strategic
partnerships, the terms that we agree upon may not be favorable to us and we may not be able to maintain such strategic partnerships if,
for example, development or approval of a product candidate is delayed or sales of an approved product are disappointing.
If we ultimately determine that entering into
strategic partnerships is in our best interest but either fail to enter into, are delayed in entering into or fail to maintain such strategic
partnerships:
|
● |
the development of our current product candidate or certain future product candidates may be terminated or delayed; |
|
● |
our planned clinical trials may be restructured or terminated; |
|
● |
our cash expenditures related to development of our current product candidate or certain future product candidates may increase significantly and we may need to seek additional financing; |
|
● |
we may be required to hire additional employees or otherwise develop expertise, such as sales and marketing expertise, for which we have not budgeted; |
|
● |
we will bear all of the risk related to the development of any such product candidates; and |
|
● |
the competitiveness of any product candidate that is commercialized could be reduced. |
To the extent we elect to enter into licensing
or collaboration agreements to partner AD04 or any future product candidates, our dependence on such relationships may adversely affect
our business.
Our commercialization strategy for certain product
candidates may depend on our ability to enter into agreements with collaborators to obtain assistance and funding for the development
and potential commercialization of these investigational product candidates. Supporting diligence activities conducted by potential collaborators
and negotiating the financial and other terms of a collaboration agreement are long and complex processes with uncertain results. Even
if we are successful in entering into one or more collaboration agreements, collaborations may involve greater uncertainty for us, as
we have less control over certain aspects of our collaborative programs than we do over our proprietary development and commercialization
programs. Our collaborators could delay or terminate their agreements, and our product candidates subject to collaborative arrangements
may never be successfully developed or commercialized.
Further, our future collaborators may develop
alternative products or pursue alternative technologies either on their own or in collaboration with others, including our competitors,
and the priorities or focus of our collaborators may shift such that our programs receive less attention or fewer resources than we would
like, or they may be terminated altogether. Any such actions by our collaborators may adversely affect our business prospects and ability
to earn revenues. In addition, we could have disputes with our future collaborators, such as the interpretation of terms in our agreements.
Any such disagreements could lead to delays in the development or commercialization of any potential products or could result in time-consuming
and expensive litigation or arbitration, which may not be resolved in our favor.
We may face particular data protection,
data security and privacy risks in connection with the European Union’s Global Data Protection Regulation and other privacy regulations.
Outside of the United States, the laws, regulations
and standards in many jurisdictions apply broadly to the collection, use, and other processing of personal information. For example, in
the European Union, the collection and use of personal data are governed by the provisions of the General Data Protection Regulation (the
“GDPR”). The GDPR, together with national legislation, regulations and guidelines of the European Union. member states governing
the processing of personal data, impose strict obligations on entities subject to the GDPR, including but not limited to: (i) accountability
and transparency requirements, and enhanced requirements for obtaining valid consent from data subjects; (ii) obligations to consider
data protection as any new products or services are developed and to limit the amount of personal data processed; (iii) obligations to
comply with the data protection rights of data subjects; and (iv) obligations to report certain personal data breaches to governmental
authorities and individuals. Data protection authorities from the different E.U. member states and other European countries may enforce
the GDPR and national data protection laws differently, and introduce additional national regulations and guidelines, which adds to the
complexity of processing European personal data. Failure to comply with the requirements of the GDPR and the related national data protection
laws may result in significant monetary fines and other administrative penalties (the GDPR authorizes fines for certain violations of
up to 4% of global annual revenue or €20 million, whichever is greater) as well as civil liability claims from individuals whose
personal data was processed. Additionally, expenses associated with compliance could reduce our operating margins.
The GDPR also prohibits the transfer of personal
data from the E.U. to countries outside of the E.U. unless made to a country deemed by the European Commission to provide adequate protection
for personal data or accomplished by means of an approved data transfer mechanism (e.g., standard contractual clauses). Data protection
authority guidance and enforcement actions that restrict companies’ ability to transfer data may increase risk relating to data
transfers or make it more difficult or impossible to transfer E.U. personal data to the U.S.
Our internal computer systems, or those
used by our CROs or other contractors or consultants, may fail or suffer security breaches.
Despite the implementation of security measures,
our internal computer systems and those of our future CROs and other contractors and consultants are vulnerable to damage from computer
viruses and unauthorized access. While we have not experienced any such material system failure or security breach to date, if such an
event were to occur and cause interruptions in our operations, it could result in a material disruption of our development programs and
our business operations. For example, the loss of clinical trial data from completed or future clinical trials could result in delays
in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Since we rely on third parties
for research and development of AD04 and expect do so for future product candidates and for the manufacture of product candidates and
to conduct clinical trials, similar events relating to their computer systems could also have a material adverse effect on our business.
To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate
disclosure of confidential or proprietary information, we could incur liability and the further development and commercialization of product
candidates could be delayed.
We have limited protection for our intellectual
property. Our licensed patents and proprietary rights may not prevent us from infringing on the rights of others or prohibit potential
competitors from commercializing products.
We intend to rely on a combination of common law
copyright, patent, trademark, and trade secret laws and measures to protect our proprietary information. We have licensed patents to protect
certain of our proprietary intellectual property and have obtained exclusive rights to license certain of the technology for which patent
protection has been obtained; however, such protection does not prevent unauthorized use of such technology. Trademark and copyright protections
may be limited, and enforcement could be too costly to be effective. It may also be possible for unauthorized third parties to copy aspects
of, or otherwise obtain and use, our proprietary information without authorization, including, but not limited to, product design, software,
customer and prospective customer lists, trade secrets, copyrights, patents and other proprietary rights and materials. Other parties
can use and register confusingly similar business, product and service names, as well as domain names, which could divert customers, resulting
in a material adverse effect on our business, operating results and financial condition.
We have not conducted an exhaustive patent search
and cannot assure you that patents do not exist or could not be filed that would negatively affect our ability to market our products
or maintain our competitive position with respect to our products. Additionally, our licensed patents may not prevent others from developing
competitive products using related technology. Furthermore, other companies that obtain patents claiming products or processes useful
to us may bring infringement actions against us. As a result, we may be required to obtain licenses from others to develop, manufacture
or market our products. We cannot assure you that we will be able to obtain any such licenses on commercially reasonable terms, if at
all.
We also rely on trade secrets and proprietary
know-how that we seek to protect, in part, by confidentiality agreements with our employees, consultants, suppliers, and licensees. We
cannot give any assurance that these third parties will not breach these agreements, that we would have adequate remedies for any breach,
or that our trade secrets will not otherwise become known or be independently developed by competitors.
We cannot assure you that the U.S. Patent and
Trademark Office (“USPTO”) will approve pending patent applications for intellectual property for which we are currently the
exclusive worldwide licensee, or that any patent issued to, or licensed by, us will provide protection that has commercial significance.
In this regard, the patent position of pharmaceutical compounds and compositions is particularly uncertain. Even issued patents may later
be modified or revoked by the USPTO in proceedings instituted by others or by us. In addition, we cannot assure you that our licensed
patents will afford protection against competitors with similar compounds or technologies, that others will not obtain patents with claims
similar to those covered by our licensed patents or applications, or that the patents of others will not adversely affect our ability
to conduct our business.
Despite licensing patents issued in more than
40 jurisdictions around the world, continuing to achieve additional foreign patent issuances and maintaining and defending foreign patents
may be more difficult than defending domestic patents because of differences in patent laws, and our licensed patent position therefore
may be stronger in the United States than abroad. In addition, the protection provided by foreign patents, once they are obtained, may
be weaker than that provided in the United States.
If we fail to successfully enforce our intellectual
property rights, our competitive position could suffer, which could harm our operating results. Competitors may challenge the validity
or scope of our licensed patents or future patents we may obtain or license. In addition, our licensed patents may not provide us with
a meaningful competitive advantage. We may be required to spend significant resources to monitor and police our licensed intellectual
property rights. We may not be able to detect infringement and our competitive position may be harmed. In addition, competitors may design
around our technology or develop competing technologies. Intellectual property rights may also be unavailable or limited in some foreign
countries, which could make it easier for competitors to capture market share.
The technology we license, our products
or our development efforts may be found to infringe upon third-party intellectual property rights.
Our commercial success depends in part on us avoiding
infringement of the patents and proprietary rights of third parties. There is a substantial amount of litigation involving patents and
other intellectual property rights in the biotechnology and pharmaceutical industries, as well as administrative proceedings for challenging
patents, including interference and reexamination proceedings before the USPTO, or oppositions and other comparable proceedings in other
jurisdictions. Recently, under the American Invents Act (“AIA”), new procedures including inter parties review and
post grant review have been implemented. These procedures are relatively new and the manner in which they are being implemented continues
to evolve, which brings additional uncertainty to our licensed patents and pending applications. Numerous U.S. and foreign issued patents
and pending patent applications, which are owned by third parties, exist in the fields in which we are developing product candidates.
As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates
may give rise to claims of infringement of the patent rights of others.
Third parties may, in the future, assert claims
or initiate litigation related to their patent, copyright, trademark and other intellectual property rights in technology that is important
to us. The asserted claims and/or litigation could include claims against us, our licensors or our suppliers alleging infringement of
intellectual property rights with respect to our products or components of those products. Regardless of the merit of the claims, they
could be time consuming, result in costly litigation and diversion of technical and management personnel, or require us to develop a non-infringing
technology or enter into license agreements. We have not undertaken an exhaustive search to discover any third party intellectual patent
rights which might be infringed by commercialization of the product candidates described herein. Although we are not currently aware of
any such third party intellectual patent rights, it is possible that such rights currently exist or might be obtained in the future. In
the event that a third party controls such rights and we are unable to obtain a license to such rights on commercially reasonable terms,
we may not be able to sell or continue to develop our products, and may be liable for damages for such infringement. We cannot assure
you that licenses will be available on acceptable terms, if at all. Furthermore, because of the potential for significant damage awards,
which are not necessarily predictable, it is not unusual to find even arguably unmeritorious claims resulting in large settlements. If
any infringement or other intellectual property claim made against us by any third party is successful, or if we fail to develop non-infringing
technology or license the proprietary rights on commercially reasonable terms and conditions, our business, operating results and financial
condition could be materially adversely affected.
If our products, methods, processes and other
technologies infringe the proprietary rights of other parties, we could incur substantial costs and we may have to:
|
● |
obtain licenses, which may not be available on commercially reasonable terms, if at all; |
|
● |
abandon an infringing drug or therapy candidate; |
|
● |
redesign our products or processes to avoid infringement; |
|
● |
stop using the subject matter claimed in the patents held by others; |
|
● |
defend litigation or administrative proceedings which may be costly whether we win or lose, and which could result in a substantial diversion of our financial and management resources. |
Parties making claims against us may seek and
obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize product candidates.
Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion
of employee resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial
damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties,
pay royalties or redesign our infringing products, which may be impossible or require substantial time and monetary expenditure. We cannot
predict whether any such license would be available at all or whether it would be available on commercially reasonable terms. Furthermore,
even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization
of product candidates. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event,
we would be unable to further develop and commercialize product candidates, which could harm our business significantly.
We may be involved in lawsuits to protect
or enforce the patents of our licensors, which could be expensive, time-consuming and unsuccessful.
Competitors may infringe the patents of our licensors.
To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming.
In addition, in an infringement proceeding, a court may decide that one or more of our licensed patents is not valid or is unenforceable,
or may refuse to stop the other party from using the technology at issue on the grounds that our licensed patents do not cover the technology
in question. An adverse result in any litigation or defense proceedings could put one or more of our licensed patents at risk of being
invalidated, held unenforceable, or interpreted narrowly and could put our licensed patent applications at risk of not issuing. Defense
of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee
resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including
treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties or redesign
our infringing products, which may be impossible or require substantial time and monetary expenditure.
Interference proceedings provoked by third parties
or brought by the USPTO may be necessary to determine the priority of inventions with respect to some of our licensed patents or patent
applications subject to pre-AIA or those of our licensors. An unfavorable outcome could result in a loss of our current licensed patent
rights and could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our
business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation or interference
proceedings may result in a decision adverse to our interests and, even if we are successful, may result in substantial costs and distract
our management and other employees. We may not be able to prevent, alone or with our licensors, misappropriation of our trade secrets
or confidential information, particularly in countries where the laws may not protect those rights as fully as in the United States.
A derivation proceeding is a trial proceeding
conducted at the Patent Trial and Appeal Board to determine whether (i) an inventor named in an earlier application derived the claimed
invention from an inventor named in the petitioner’s application; and (ii) the earlier application claiming such invention was filed
without authorization. An applicant subject to the first-inventor-to-file provisions may file a petition to institute a derivation proceeding
only within one year of the first publication of a claim to an invention that is the same or substantially the same as the earlier application’s
claim to the invention. The petition must be supported by substantial evidence that the claimed invention was derived from an inventor
named in the petitioner’s application. Derivation proceedings may result in a decision adverse to our interests and, even if we
are successful, may result in substantial costs and distract our management and other employees.
Furthermore, because of the substantial amount
of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could
be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings,
motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could
have a substantial adverse effect on the price of our shares of common stock.
Obtaining and maintaining patent protection
depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent
agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
Periodic maintenance fees on any issued patent
are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent. The USPTO and various foreign
governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during
the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance
with the applicable rules, there are situations in which non-compliance can result in abandonment or lapse of the patent or patent application,
resulting in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could result in abandonment
or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time
limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, our competitors might be able
to enter the market, which would have a material adverse effect on our business.
Patents are subject to changing legal interpretation
by the USPTO and the Courts.
If the U.S. Supreme Court, other federal courts,
or the USPTO were to change the standards of patentability such changes could have a negative impact on our business. Recent court cases
have made it more difficult to protect certain types of inventions. For instance, on October 30, 2008, the Court of Appeals for the Federal
Circuit issued a decision that methods or processes cannot be patented unless they are tied to a machine or involve a physical transformation.
On March 20, 2012, in the case Mayo v. Prometheus, the U.S. Supreme Court invalidated a patent focused on a diagnostic process
because the patent claim embodied a law of nature. On July 3, 2012, the USPTO issued its Interim Guidelines for Subject Matter Eligibility
Analysis of Process Claims Involving Laws of Nature in view of the Prometheus decision. It remains to be seen how these guidelines
will play out in the actual prosecution of diagnostic claims. Similarly, it remains to be seen how lower courts will interpret the Prometheus
decision. Some aspects of our technology involve processes that may be subject to this evolving standard and we cannot guarantee that
any of our pending process claims will be patentable as a result of such evolving standards.
We may be subject to claims that our employees,
consultants or independent contractors have wrongfully used or disclosed confidential information of third parties.
We have received confidential and proprietary
information from third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical
companies. We may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise
used or disclosed confidential information of these third parties or our employees’ former employers. Litigation may be necessary
to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial cost
and be a distraction to our management and employees.
Our ability to generate product revenues
will be diminished if our products sell for inadequate prices or patients are unable to obtain adequate levels of reimbursement.
Our ability to commercialize our products, alone
or with collaborators, will depend in part on the extent to which reimbursement will be available from:
|
● |
government and health administration authorities; |
|
● |
private health maintenance organizations and health insurers; and |
|
● |
other healthcare payers. |
Patients generally expect that products such as
ours are covered and reimbursed by third-party payors for all or part of the costs and fees associated with their use. If such products
are not covered and reimbursed then patients may be responsible for the entire cost of the product, which can be substantial. Therefore,
health care providers generally do not prescribe products that are not covered and reimbursed by third-party payors in order to avoid
subjecting their patients to such financial liability. The existence of adequate coverage and reimbursement for the products by government
and private insurance plans is central to the acceptance of AD04 and any future products we provide.
During the past several years, third-party payors
have undertaken cost-containment initiatives including different payment methods, monitoring health care expenditures, and anti-fraud
initiatives. For some governmental programs, such as Medicaid, coverage and reimbursement differ from state to state, and some state Medicaid
programs may not pay an adequate amount for AD04 or any of our other products or may make no payment at all. Furthermore, the health care
industry in the United States has experienced a trend toward cost containment as government and private insurers seek to control health
care costs by imposing lower payment rates and negotiating reduced contract rates with service providers. Therefore, we cannot be certain
that our services will be reimbursed at a level that is sufficient to meet our costs.
Obtaining coverage and reimbursement approval
of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to the
payor supporting scientific, clinical and cost-effectiveness data for the use of our products. Even if we obtain coverage for a given
product, the resulting reimbursement payment rates might not be adequate for us to achieve or sustain profitability or may require co-payments
that patients find unacceptably high. Patients are unlikely to use AD04 or any future product candidates unless coverage is provided and
reimbursement is adequate to cover a significant portion of the cost of AD04 or any future product candidates.
We intend to seek approval to market AD04 and
future product candidates in both the United States and in selected foreign jurisdictions. If we obtain approval in one or more foreign
jurisdictions for AD04 or any future product candidates, we will be subject to rules and regulations in those jurisdictions. In some foreign
countries, particularly those in the European Union, the pricing of drugs is subject to governmental control. In these countries, pricing
negotiations with governmental authorities can take considerable time after obtaining marketing approval of a product candidate. In addition,
market acceptance and sales of product candidates will depend significantly on the availability of adequate coverage and reimbursement
from third-party payors for product candidates and may be affected by existing and future health care reform measures.
Third-party payors, whether domestic or foreign,
or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In both the United States
and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could
impact our ability to sell our products profitably. In particular, in 2010, the Patient Protection and Affordable Care Act, as amended
by the Health Care and Education Affordability Reconciliation Act (collectively, the “Healthcare Reform Act”), was enacted.
The Healthcare Reform Act and its implementing regulations, among other things, revised the methodology by which rebates owed by manufacturers
to the state and federal government for covered outpatient drugs, including product candidates, under the Medicaid Drug Rebate Program
are calculated, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, extended the
Medicaid Drug Rebate program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations, subjected
manufacturers to new annual fees and taxes for certain branded prescription drugs, and provided incentives to programs that increase the
federal government’s comparative effectiveness research.
Other legislative changes have been proposed and
adopted in the United States since the Healthcare Reform Act was enacted. In August 2011, the Budget Control Act of 2011, among other
things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending
a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering
the legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to
providers up to 2% per fiscal year. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012 (the “ATRA”)
which delayed for another two months the budget cuts mandated by these sequestration provisions of the Budget Control Act of 2011. In
March 2013, the President signed an executive order implementing sequestration, and in April 2013, the 2% Medicare payment reductions
went into effect. The ATRA also, among other things, reduced Medicare payments to several providers, including hospitals, imaging centers
and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers
from three to five years.
There have been, and likely will continue to be,
legislative and regulatory proposals at the foreign, federal and state levels directed at broadening the availability of healthcare and
containing or lowering the cost of healthcare. We cannot predict the initiatives that may be adopted in the future, particularly in light
of the new presidential administration in the United States, and any proposed changes to healthcare laws that could potentially affect
our clinical development or regulatory strategy. The continuing efforts of the government, insurance companies, managed care organizations
and other payors of healthcare services to contain or reduce costs of healthcare and/or impose price controls may adversely affect:
|
● |
the demand for AD04, or future product candidates, if we obtain regulatory approval; |
|
● |
our ability to set a price that we believe is fair for our products; |
|
● |
our ability to generate revenue and achieve or maintain profitability; |
|
● |
the level of taxes that we are required to pay; and |
|
● |
the availability of capital. |
Any reduction in reimbursement from Medicare,
Medicaid or other government programs may result in a similar reduction in payments from private payors, which may adversely affect our
future profitability.
If we are unable to obtain adequate coverage
and reimbursement for our tests, it is unlikely that our tests will gain widespread acceptance.
Use of our product candidate will require pre-treatment
screening. Our strategy for AD04 aims to integrate pre-treatment screening into the drug label, effectively creating a patient-specific
or “precision” treatment into one integrated therapeutic offering. Our ability to generate revenue will depend upon the availability
of adequate coverage and reimbursement for our tests from third-party payors, including government programs such as Medicare and Medicaid,
private insurance plans and managed care programs. Health care providers that order diagnostic services generally expect that those diagnostic
services are covered and reimbursed by third-party payors for all or part of the costs and fees associated with the diagnostic tests they
order. If such diagnostic tests are not covered and reimbursed then their patients may be responsible for the entire cost of the test,
which can be substantial. Therefore, health care providers generally do not order tests that are not covered and reimbursed by third-party
payors in order to avoid subjecting their patients to such financial liability. The existence of adequate coverage and reimbursement for
the procedures performed by us by government and private insurance plans is central to the acceptance of our product candidate. During
the past several years, third-party payors have undertaken cost-containment initiatives including different payment methods, monitoring
health care expenditures, and anti-fraud initiatives. In addition, the Centers for Medicare & Medicaid Services, or CMS, which administers
the Medicare program, has taken the position that the algorithm portion of multi-analyst algorithmic assays, or MAAAs, is not a clinical
laboratory test and is therefore not reimbursable under the Medicare program. Although this position is only applicable to tests with
a CMS determined national payment amount, it is possible that the local MACs, who make coverage and payment determinations for tests such
as ours may adopt this policy and reduce payment for such test. If that were to happen, reimbursement for our pre-screening tests would
be uncertain. We may not be able to achieve or maintain profitability if third-party payors deny coverage or reduce their current levels
of payment, or if our costs of production increase faster than increases in reimbursement levels. Further, many private payors use coverage
decisions and payment amounts determined by CMS as guidelines in setting their coverage and reimbursement policies. Future action by CMS
or other government agencies may diminish payments to clinical laboratories, physicians, outpatient centers and/or hospitals. Those private
payors that do not follow the Medicare guidelines may adopt different coverage and reimbursement policies for us and coverage and the
amount of reimbursement under those polices is uncertain. For some governmental programs, such as Medicaid, coverage and reimbursement
differ from state to state, and some state Medicaid programs may not pay an adequate amount for MyPRS® or may make no payment
at all. As the portion of the U.S. population over the age of 65 and eligible for Medicare continues to grow, we may be more vulnerable
to coverage and reimbursement limitations imposed by CMS. Furthermore, the health care industry in the United States has experienced a
general trend toward cost containment as government and private insurers seek to control health care costs through various mechanisms,
including imposing limitations on payment rates and negotiating reduced contract rates with service providers, among other things. Therefore,
we cannot be certain that our services will be reimbursed at a level that is sufficient to meet our costs.
A variety of risks associated with marketing
AD04 or any future product candidates internationally could materially adversely affect our business.
We plan to seek regulatory approval of AD04 and
any future product candidates outside of the United States, in particular in European markets, and, accordingly, we expect that we will
be subject to additional risks related to operating in foreign countries if we obtain the necessary approvals, including:
|
● |
differing regulatory and reimbursement requirements in foreign countries; |
|
● |
unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements; |
|
● |
economic weakness, including inflation, or political instability in particular foreign economies and markets; |
|
● |
compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; |
|
● |
foreign taxes, including withholding of payroll taxes; |
|
● |
foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country; |
|
● |
compliance with U.S. and foreign export control regulations, including economic sanctions and embargo programs, each of which may be subject to unexpected changes; |
|
● |
difficulties staffing and managing foreign operations; |
|
● |
workforce uncertainty in countries where labor unrest is more common than in the United States; |
|
● |
potential liability under the FCPA or comparable foreign regulations; |
|
● |
challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect intellectual property rights to the same extent as the United States; |
|
● |
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; |
|
● |
business interruptions resulting from geo-political actions, including war and terrorism; and |
|
● |
potential difficulties that may arise with pharmaceutical company partners under license or other agreement to jointly develop, seek regulatory approval, and commercialize our products. |
These and other risks associated with our international
operations may materially adversely affect our ability to attain or maintain profitable operations.
We may not successfully effect our intended
expansion.
Our success will depend upon the expansion of
our operations and the effective management of our growth, which will place a significant strain on our management and on our administrative,
operational and financial resources. To manage this growth, we must expand our facilities, augment our operational, financial and management
systems and hire additional qualified personnel. We will need to hire additional qualified personnel with expertise in preclinical and
clinical research, government regulation, formulation and manufacturing, sales and marketing and accounting and financing. In particular,
over the next 12 months, we expect to hire additional new employees. We compete for qualified individuals with numerous biopharmaceutical
companies, universities and other research institutions. Competition for such individuals is intense, and we cannot be certain that our
search for such personnel will be successful. Attracting and retaining qualified personnel will be critical to our success. If we are
unable to manage our growth effectively, our business would be harmed.
We rely on key executive officers and scientific,
regulatory and medical advisors, and their knowledge of our business and technical expertise would be difficult to replace.
Because of the specialized nature of our business,
our ability to maintain a competitive position depends on our ability to attract and retain qualified management and other personnel.
We cannot assure you that we will be able to continue to attract or retain such persons.
We are highly dependent on our principal scientific,
regulatory and medical advisors and our chief executive officer. We do not have an insurance policy on the life of our chief executive
officer, William B. Stilley; and we do not have “key person” life insurance policies for any of our other officers or advisors.
The loss of the technical knowledge and management and industry expertise of any of our key personnel could result in delays in product
development, loss of customers and sales and diversion of management resources, which could adversely affect our operating results.
Certain of our officers may have a conflict
of interest.
Certain of our officers are currently working
for our company on a part-time basis and we expect that they will continue to do so. Our employment agreements with our Chief Operating
Officer and Chief Financial Officer provide that they will devote 80% and 75% of their business time, respectively, to our matters, with
their remaining business time devoted to other matters including, without limitation, employment at other companies that are non-competitive
with us, which may result in a lack of availability when needed due to responsibilities with other requirements. Our consulting agreement
with our Chief Medical Officer provides that he will devote 75% of his business time to our matters, with his remaining business time
devoted to other matters including, without limitation, employment at other companies that are non-competitive with us, which may result
in a lack of availability when needed due to responsibilities with other requirements.
We may acquire other businesses or form
joint ventures or make investments in other companies or technologies that could harm our operating results, dilute our stockholders’
ownership, increase our debt or cause us to incur significant expense.
As part of our business strategy, we may pursue
acquisitions of businesses and assets, such as the Acquisition of Purnovate. We also may pursue strategic alliances and joint ventures
that leverage our technology and industry experience to expand our offerings or other capabilities. Though certain company personnel have
business development and corporate transaction experience, including with licensing, mergers and acquisitions, and strategic partnering,
as a company we have no experience with acquiring other companies and limited experience with forming strategic alliances and joint ventures.
We may not be able to find suitable partners or acquisition candidates, and we may not be able to complete such transactions on favorable
terms, if at all. If we make any acquisitions, we may not be able to integrate these acquisitions successfully into our existing business,
and we could assume unknown or contingent liabilities. Any future acquisitions also could result in significant write-offs or the incurrence
of debt and contingent liabilities, any of which could have a material adverse effect on our financial condition, results of operations
and cash flows. Integration of an acquired company also may disrupt ongoing operations and require management resources that would otherwise
focus on developing our existing business. We may experience losses related to investments in other companies, which could have a material
negative effect on our results of operations. We may not identify or complete these transactions in a timely manner, on a cost-effective
basis, or at all, and we may not realize the anticipated benefits of any acquisition, technology license, strategic alliance or joint
venture.
To finance any acquisitions or joint ventures,
we may choose to issue shares of our common stock as consideration, which would dilute the ownership of our stockholders. If the price
of our common stock is low or volatile, we may not be able to acquire other companies or fund a joint venture project using our stock
as consideration. Alternatively, it may be necessary for us to raise additional funds for acquisitions through public or private financings.
Additional funds may not be available on terms that are favorable to us, or at all.
Declining general economic or business conditions
may have a negative impact on our business.
Continuing concerns over U.S. health care reform
legislation and energy costs, geopolitical issues, including those in Eastern Europe, the availability and cost of credit and government
stimulus programs in the United States and other countries have contributed to increased volatility and diminished expectations for the
global economy. These factors, combined with low business and consumer confidence and high unemployment, precipitated an economic slowdown
and recession and stagnant economy for more than a decade. Additionally, political changes in the U.S. and elsewhere in the world have
created a level of uncertainty in the markets. If the economic climate does not improve or deteriorate, our business, as well as the financial
condition of our suppliers and our third-party payors, could be adversely affected, resulting in a negative impact on our business, financial
condition and results of operations.
Health care policy changes, including legislation
reforming the U.S. health care system and other legislative initiatives, may have a material adverse effect on our financial condition,
results of operations and cash flows.
Government payors, such as Medicare and Medicaid,
have taken steps and can be expected to continue to take steps to control the cost, utilization and delivery of health care services,
including clinical laboratory test services.
In March 2010, U.S. President Barack Obama signed
the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the
ACA, which made a number of substantial changes in the way health care is financed by both governmental and private insurers. It is unclear
what, if any, changes the new administration will make to the health care system. We cannot predict whether future health care initiatives
will be implemented at the federal or state level, or how any future legislation or regulation may affect us.
Risks Related to Our Securities and Investing
in Our Securities
Certain of our shareholders have sufficient
voting power to make corporate governance decisions that could have a significant influence on us and the other stockholders.
Our officers and directors currently beneficially
own (would own, if they collectively exercised all owned warrants and options exercisable within 60 days) approximately 22% of our outstanding
common stock. Bankole Johnson, our Chief Medical Officer and our former Chairman of the Board of Directors, Mr. Stilley, our Chief Executive
Officer and a director, Kevin Schuyler, a director, and James W. Newman, a director, beneficially own approximately 3.5%, 9.9%, 4.5%,
and 3.5%, respectively, of our common stock. As a result, our directors currently have significant influence over our management and affairs
and over matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions.
In addition, this concentration of ownership may delay or prevent a change in our control and might affect the market price of our common
stock, even when a change in control may be in the best interest of all stockholders. Furthermore, the interests of this concentration
of ownership may not always coincide with our interests or the interests of other stockholders. Accordingly, these stockholders could
cause us to enter into transactions or agreements that we would not otherwise consider.
Future sales and issuances of our common
stock or rights to purchase common stock, including pursuant to our equity incentive plans and outstanding warrants, could result in additional
dilution of the percentage ownership of our stockholders and could cause our stock price to fall.
We expect that significant additional capital
may be needed in the future to continue our planned operations, including conducting clinical trials, commercialization efforts, expanded
research and development activities and costs associated with operating a public company. To raise capital, we may sell common stock,
convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time.
If we sell common stock, convertible securities or other equity securities, investors may be materially diluted by subsequent sales. Such
sales may also result in material dilution to our existing stockholders, and new investors could gain rights, preferences and privileges
senior to the holders of our common stock. Pursuant to our 2017 equity incentive plan, which became effective on the business day prior
to the public trading date of our common stock, our management is authorized to grant equity awards to our employees, officers, directors
and consultants.
Initially, the aggregate number of shares of our
common stock that might be issued pursuant to stock awards under our 2017 equity incentive plan was 1,750,000 shares, which has been since
increased to 7,500,000 at our 2021 Annual Stockholders Meeting, and of which 2,347,716 remain available for grant as of the date hereof.
Increases in the number of shares available for future grant or purchase may result in additional dilution, which could cause our stock
price to decline.
At December 31, 2021, we had outstanding (i) warrants
to purchase 7,990,271 shares of common stock outstanding at exercise prices ranging from $0.005 to $7.634 (with a weighted average exercise
price of $4.82), and (ii) options to purchase 3,585,310 shares of common stock at a weighted average exercise price of $2.65 per share.
The issuance of the shares of common stock underlying the options and warrants will have a dilutive effect on the percentage ownership
held by holders of our common stock.
At the date of this filing, having issued a significant
number of options and seen a significant number of warrant exercised, we had outstanding (i) warrants to purchase 13,833,159 shares of
common stock outstanding at exercise prices ranging from $0.005 to $7.634 (with a weighted average exercise price of $3.51), and (ii)
options to purchase 3,585,310 shares of common stock at a weighted average exercise price of $2.65 per share. The issuance of the shares
of common stock underlying the options and warrants will have a dilutive effect on the percentage ownership held by holders of our common
stock.
We have additional securities available
for issuance, which, if issued, could adversely affect the rights of the holders of our common stock.
Our Certificate of Incorporation authorizes the
issuance of 50,000,000 shares of common stock and 5,000,000 shares of preferred stock. The common stock and preferred stock, as well as
the awards available for issuance under our 2017 equity incentive plan, can be issued by our board of directors, without stockholder approval.
Any future issuances of such stock would further dilute the percentage ownership in us held by holders of our common stock and may be
issued at prices below the initial price offering. In addition, the issuance of preferred stock may be used as an “anti-takeover”
device without further action on the part of our stockholders, and may adversely affect the holders of the common stock.
If we issue preferred stock with superior
rights than our common stock, it could result in a decrease in the value of our common stock and delay or prevent a change in control
of us.
Our board of directors is authorized to issue
5,000,000 shares of preferred stock in series. The issuance of any preferred stock having rights superior to those of the common stock
may result in a decrease in the value or market price of our common stock. Holders of preferred stock may have the right to receive dividends,
certain preferences in liquidation and conversion rights and rights to elect directors. The issuance of preferred stock could, under certain
circumstances, have the effect of delaying, deferring or preventing a change in control of us without further vote or action by the stockholders
and may adversely affect the voting and other rights of the holders of our common stock.
We have never paid dividends and have no
plans to pay dividends in the future.
Holders of our common stock are entitled to receive
such dividends as may be declared by our board of directors. To date, we have paid no cash dividends on our preferred or common stock
and we do not expect to pay cash dividends in the foreseeable future. We intend to retain future earnings, if any, to provide funds for
operations of our business. Therefore, any return investors in our preferred or common stock may have will be in the form of appreciation,
if any, in the market value of their common stock.
Our failure to meet the continued listing
requirements of The Nasdaq Capital Market could result in a de-listing of our common stock.
Our shares of common stock are listed for trading
on The Nasdaq Capital Market under the symbol “ADIL” and our warrants issued in connection with our initial public offering
are listed for trading on The Nasdaq Capital Market under the symbol “ADILW.” If we fail to satisfy the continued listing
requirements of The Nasdaq Capital Market such as the corporate governance requirements, the stockholder’s equity requirement or
the minimum closing bid price requirement, The Nasdaq Capital Market may take steps to de-list our common stock or warrants. Such a de-listing
or even notification of failure to comply with such requirements would likely have a negative effect on the price of our common stock
and warrants would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a de-listing, we would
take actions to restore our compliance with The Nasdaq Capital Market’s listing requirements, but we can provide no assurance that
any such action taken by us would allow our common stock become listed again, stabilize the market price or improve the liquidity of our
common stock, prevent our common stock from dropping below The Nasdaq Capital Market, minimum bid price requirement or prevent future
non-compliance with The Nasdaq Capital Market’s listing requirements.
The National Securities Markets Improvement Act
of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred
to as “covered securities.” Because our common stock is listed on The Nasdaq Capital Market, our common stock is covered securities.
Although the states are preempted from regulating the sale of covered securities, the federal statute does allow the states to investigate
companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the
sale of covered securities in a particular case. Further, if we were to be delisted from The Nasdaq Capital Market, our common stock would
cease to be recognized as covered securities and we would be subject to regulation in each state in which we offer our securities.
We are an “emerging growth company,”
and we cannot be certain if the reduced SEC reporting requirements applicable to emerging growth companies will make our common stock
less attractive to investors.
We are an “emerging growth company”
as defined in the JOBS Act. We will remain an “emerging growth company” until the earliest to occur of (i) the last day of
the fiscal year during which we have total annual gross revenue of $1.07 billion or more (subject to adjustment for inflation), (ii) the
last day of the fiscal year following the fifth anniversary of the first sale of our common stock pursuant to an effective registration
statement, (iii) the date on 36 • actual receipt of an improper benefit or profit in money, property, or services; or • active
and deliberate dishonesty by the director or officer that was established by a final judgment as being material to the cause of action
adjudicated. which we have, during the previous 3-year period, issued more than $1.0 billion in non-convertible debt, or (iv) the date
on which we are deemed to be a “large accelerated filer.” We intend to take advantage of exemptions from various reporting
requirements that are applicable to most other public companies, whether or not they are classified as “emerging growth companies,”
including, but not limited to, an exemption from the provisions of Section 404(b) of Sarbanes-Oxley requiring that our independent registered
public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting. An attestation
report by our auditor would require additional procedures by them that could detect problems with our internal control over financial
reporting that are not detected by management. If our system of internal control over financial reporting is not determined to be appropriately
designed or operating effectively, it could require us to restate financial statements, cause us to fail to meet reporting obligations,
and cause investors to lose confidence in our reported financial information. The JOBS Act also provides that an “emerging growth
company” can take advantage of the extended transition period provided in the Securities Act, for complying with new or revised
accounting standards. However, we have chosen to “opt out” of this extended transition period and, as a result, we will comply
with new or revised accounting standards on or prior to the relevant dates on which adoption of such standards is required for all public
companies that are not emerging growth companies. Our decision to opt out of the extended transition period for complying with new or
revised accounting standards is irrevocable. We cannot predict if investors will find our common stock less attractive because we intend
to rely on certain of these exemptions and benefits under the JOBS Act.
As a result of being a public company, we
are subject to additional reporting and corporate governance requirements that will require additional management time, resources and
expense.
As a public company, and particularly after we
are no longer an emerging growth company, we will incur significant legal, accounting and other expenses that we did not incur as a private
company. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of The Nasdaq
Capital Market and other applicable securities rules and regulations impose various requirements on public companies, including the obligation
to file with the SEC annual and quarterly information and other reports that are specified in the Securities Exchange Act of 1934, as
amended (the “Exchange Act”), and to establish and maintain effective disclosure and financial controls and corporate governance
practices. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these
rules and regulations increase our legal and financial compliance costs and will make some activities more time-consuming and costly.
We cannot predict or estimate the amount of additional
costs we may incur or the timing of such costs. These rules and regulations are often 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.
Our common stock has often been thinly traded,
so you may be unable to sell at or near ask prices or at all if you need to sell your shares to raise money or otherwise desire to liquidate
your shares.
To date, there have been many days on which limited
trading of our common stock took place. We cannot predict the extent to which investors’ interests will lead to an active trading
market for our common stock or whether the market price of our common stock will be volatile. If an active trading market does not develop,
investors may have difficulty selling any of our common stock that they buy. We are likely to be too small to attract the interest of
many brokerage firms and analysts. We cannot give you any assurance that an active public trading market for our common stock will develop
or be sustained. The market price of our common stock could be subject to wide fluctuations in response to quarterly variations in our
revenues and operating expenses, announcements of new products or services by us, significant sales of our common stock, including “short”
sales, the operating and stock price performance of other companies that investors may deem comparable to us, and news reports relating
to trends in our markets or general economic conditions.
Our stock price has fluctuated in the past,
has recently been volatile and may be volatile in the future, and as a result, investors in our common stock could incur substantial losses.
The trading price of our common stock has been
and is expected to continue to be volatile and has been and may continue to be subject to wide fluctuations in response to various factors,
some of which are beyond our control, including limited trading volume. On March 23, 2022, the reported low sale price of our common stock
was $2.00, the reported high sale price was $2.16 and closing price of our common stock was $2.12 while on December 31, 2021 the closing
price of our common stock was $2.70. We may incur rapid and substantial decreases in our stock price in the foreseeable future that are
unrelated to our operating performance for prospects. In addition to the factors discussed in this “Risk Factors” section
and elsewhere in this Annual Report, these factors include:
|
● |
the commencement, enrollment or results of the planned clinical trials of AD04 or any future clinical trials we may conduct, or changes in the development status of AD04 or any product candidates; |
|
● |
any delay in our regulatory filings for our product candidate and any adverse development or perceived adverse development with respect to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a “refusal to file” letter or a request for additional information; |
|
● |
adverse results or delays in clinical trials; |
|
● |
our decision to initiate a clinical trial, not to initiate a clinical trial or to terminate an existing clinical trial; |
|
● |
adverse regulatory decisions, including failure to receive regulatory approval of our product candidate; |
|
● |
changes in laws or regulations applicable to our products, including but not limited to clinical trial requirements for approvals; |
|
● |
adverse developments concerning our manufacturers; |
|
● |
our inability to obtain adequate product supply for any approved product or inability to do so at acceptable prices; |
|
● |
our inability to establish collaborations if needed; |
|
● |
our failure to commercialize AD04; |
|
● |
additions or departures of key scientific or management personnel; |
|
● |
unanticipated serious safety concerns related to the use of AD04; |
|
● |
introduction of new products or services offered by us or our competitors; |
|
● |
announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by us or our competitors; |
|
● |
our ability to effectively manage our growth; |
|
● |
the size and growth of our initial target markets; |
|
● |
our ability to successfully treat additional types of indications or at different stages; |
|
● |
actual or anticipated variations in quarterly operating results; |
|
● |
our failure to meet the estimates and projections of the investment community or that we may otherwise provide to the public; |
|
● |
publication of research reports about us or our industry, or positive or negative recommendations or withdrawal of research coverage by securities analysts; |
|
● |
changes in the market valuations of similar companies; |
|
● |
overall performance of the equity markets; |
|
● |
sales of our common stock by us or our stockholders in the future; |
|
● |
trading volume of our common stock and declines in the market prices of stocks generally; |
|
● |
changes in accounting practices; |
|
● |
ineffectiveness of our internal controls; |
|
● |
disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our or our licensee’s technologies; |
|
● |
significant lawsuits, including patent or stockholder litigation; |
|
● |
general political and economic conditions; and |
|
● |
other events or factors, many of which are beyond our control, including those resulting from such events, or the prospect of such events, including war, terrorism and other international conflicts, including the conflict in Eastern Europe, public health issues including health epidemics or pandemics, such as the recent outbreak of the novel coronavirus (COVID-19), and natural disasters such as fire, hurricanes, earthquakes, tornados or other adverse weather and climate conditions, whether occurring in the United States or elsewhere, could disrupt our operations, disrupt the operations of our suppliers or result in political or economic instability. |
In addition, the stock market in general, and
The Nasdaq Capital Market and biopharmaceutical companies in particular, have experienced extreme price and volume fluctuations that have
often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively
affect the market price of our common stock, regardless of our actual operating performance. Since the stock price of our common stock
has fluctuated in the past, has recently been volatile and may be volatile in the future, investors in our common stock could incur substantial
losses. In the past, securities class action litigation has often been instituted against companies following periods of volatility in
the market price of a company’s securities. This type of litigation, if instituted, could result in substantial costs and a diversion
of management’s attention and resources, which would harm our business, operating results or financial condition.
Our need for future financing may result
in the issuance of additional securities which will cause investors to experience dilution.
Our cash requirements may vary from those now
planned depending upon numerous factors, including the result of future research and development activities. We will require additional
funds in the future to complete our clinical trials of AD04. There are no other commitments by any person for future financing. Though
we believe a successful Phase 3 trial will be a significant value creation event for us, our securities may be offered to other investors
at a price lower than the price per share on The Nasdaq Capital Market, or upon terms which may be deemed more favorable than offered
previously. In addition, the issuance of securities in any future financing using our securities may dilute an investor’s equity
ownership. Moreover, we may issue derivative securities, including options and/or warrants, from time to time, to procure qualified personnel
or for other business reasons. The issuance of any such derivative securities, which is at the discretion of our board of directors, may
further dilute the equity ownership of our stockholders. No assurance can be given as to our ability to procure additional financing,
if required, and on terms deemed favorable to us. To the extent additional capital is required and cannot be raised successfully, we may
then have to limit our then current operations and/or may have to curtail certain, if not all, of our business objectives and plans.
Fluctuations in the international currency
markets may significantly impact the cost of our planned Phase 3 trial.
Many of the costs associated with our ongoing
ONWARD Phase 3 trial and any future trials, presently expected to require approximately $11 million to complete, are denominated in Euros,
while our funding is held in US Dollars. A change in the value of the Euro relative to the US Dollar may significantly impact the cost
of our trial, positively or negatively.
The application of the “penny stock”
rules to our common stock could limit the trading and liquidity of the common stock, adversely affect the market price of our common stock
and increase your transaction costs to sell those shares.
If our common stock is no longer listed on The
Nasdaq Capital Market and becomes traded on a securities market or exchange which is not registered as a national securities exchange
with the SEC under Section 6 of the Exchange Act, as long as the trading price of our common stock is below $5 per share, the open-market
trading of our common stock will be subject to the “penny stock” rules, unless we otherwise qualify for an exemption from
the “penny stock” definition. The “penny stock” rules impose additional sales practice requirements on certain
broker-dealers who sell securities to persons other than established customers and accredited investors (generally those with assets in
excess of $1.0 million or annual income exceeding $200,000 or $300,000 together with their spouse). These regulations, if they apply,
require the delivery, prior to any transaction involving a penny stock, of a disclosure schedule explaining the penny stock market and
the associated risks. Under these regulations, certain brokers who recommend such securities to persons other than established customers
or certain accredited investors must make a special written suitability determination regarding such a purchaser and receive such purchaser’s
written agreement to a transaction prior to sale. These regulations may have the effect of limiting the trading activity of our common
stock, reducing the liquidity of an investment in our common stock and increasing the transaction costs for sales and purchases of our
common stock as compared to other securities. The stock market in general and the market prices for penny stock companies in particular,
have experienced volatility that often has been unrelated to the operating performance of such companies. These broad market and industry
fluctuations may adversely affect the price of our stock, regardless of our operating performance. Stockholders should be aware that,
according to SEC Release No. 34-29093, the market for penny stocks has suffered in recent years from patterns of fraud and abuse. Such
patterns include: (i) control of the market for the security by one or a few broker-dealers that are often related to the promoter or
issuer; (ii) manipulation of prices through prearranged matching of purchases and sales and false and misleading press releases; (iii)
boiler room practices involving high-pressure sales tactics and unrealistic price projections by inexperienced sales persons; (iv) excessive
and undisclosed bid-ask differential and markups by selling broker-dealers; and (v) the wholesale dumping of the same securities by promoters
and broker-dealers after prices have been manipulated to a desired level, along with the resulting inevitable collapse of those prices
and with consequent investor losses. The occurrence of these patterns or practices could increase the volatility of our share price.
Provisions in our corporate charter documents
and under Delaware law could make an acquisition of our company, 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 corporate charter and our bylaws
may discourage, delay or prevent a merger, acquisition or other change in control of our company that stockholders may consider favorable,
including transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price that
investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock.
In addition, because our board of directors is responsible for appointing the members of our management team, 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. Among other things, these provisions:
|
● |
our board of directors is divided into three classes, one class of which is elected each year by our stockholders with the directors in each class to serve for a three-year term; |
|
● |
the authorized number of directors can be changed only by resolution of our board of directors; |
|
● |
directors may be removed only by the affirmative vote of the holders of at least sixty percent (60%) of our voting stock, whether for cause or without cause; |
|
|
|
|
● |
our bylaws may be amended or repealed by our board of directors or by the affirmative vote of sixty-six and two-thirds percent (66 2/3%) of our stockholders; |
|
|
|
|
● |
stockholders may not call special meetings of the stockholders or fill vacancies on the board of directors; |
|
● |
our board of directors will be authorized to issue, without stockholder approval, preferred stock, the rights of which will be determined at the discretion of the board of directors and that, if issued, could operate as a “poison pill” to dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that our board of directors does not approve; |
|
● |
our stockholders do not have cumulative voting rights, and therefore our stockholders holding a majority of the shares of common stock outstanding will be able to elect all of our directors; and |
|
● |
our stockholders must comply with advance notice provisions to bring business before or nominate directors for election at a stockholder meeting. |
Moreover, because we are incorporated in Delaware,
we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess
of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction
in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed
manner.
Our Certificate of Incorporation and our
bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for certain types of state actions that
may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes
with us or our directors, officers, or employees.
Our Certificate of Incorporation and our bylaws
provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive
forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of a fiduciary
duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision
of the DGCL or our certificate of incorporation or bylaws (as either may be amended from time to time), or (iv) any action asserting a
claim governed by the internal affairs doctrine. The exclusive forum provision does not apply to suits brought to enforce any liability
or duty created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction.
To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction
over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore,
Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty
or liability created by the Securities Act or the rules and regulations thereunder.
These exclusive-forum provisions may limit a stockholder’s
ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, employees, control persons,
underwriters, or agents, which may discourage lawsuits against us and our directors, employees, control persons, underwriters, or agents.
Additionally, a court could determine that the exclusive forum provision is unenforceable, and our stockholders will not be deemed to
have waived our compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find these provisions
of our bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur
additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition,
or results of operations.
If securities or industry analysts do not
publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.
The trading market for our common stock will depend
in part on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts
do not currently, and may never, publish research on our company. If no securities or industry analysts commence coverage of our company,
the trading price for our stock would likely be negatively impacted. In the event securities or industry analysts initiate coverage, if
one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our
stock price may decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly,
demand for our stock could decrease, which might cause our stock price and trading volume to decline.
The warrants that we have issued are speculative
in nature.
The warrants that we have issued do not confer
any rights of common stock ownership on their holders except as otherwise provided in the warrants. Specifically, commencing on the date
of issuance, holders of the warrants may exercise their right to acquire the common stock and pay the exercise price to acquire the warrants.
There can be no assurance that the market value of the warrants will equal or exceed their public offering price. In the event our common
stock price does not exceed the exercise price of the warrants during the period when the warrants are exercisable, the warrants may not
have any value.
Holders of the warrants will have no rights
as a common stockholder except as otherwise provided in the warrants until they acquire our common stock.
Until holders of warrants acquire shares of our
common stock upon exercise of their warrants, they will have no rights with respect to shares of our common stock issuable upon exercise
of their warrant except as otherwise provided in the warrant. Upon exercise of a warrant, a holder will be entitled to exercise the rights
of a common stockholder as to the security exercised only as to matters for which the record date occurs after the exercise.
There is no established market for the warrants
issued in our follow-on offering and those issued prior to our initial public offering.
There is no established trading market for the
warrants issued in our follow-on offering and those issued prior to our initial public offering and we do not expect a market to develop.
We have not applied for the listing of such warrants on any national securities exchange or other trading market. Without an active trading
market, the liquidity of the warrants will be limited.
Provisions of the warrants issued in our
public offerings could discourage an acquisition of us by a third party.
In addition to the discussion of the provisions
of our certificate of incorporation, our bylaws, certain provisions of the warrants offered in our public offerings could make it more
difficult or expensive for a third party to acquire us. The warrants prohibit us from engaging in certain transactions constituting “fundamental
transactions” unless, among other things, the surviving entity assumes our obligations under the warrants. These and other provisions
of the warrants could prevent or deter a third party from acquiring us even where the acquisition could be beneficial to you.
