General
Sunesis Pharmaceutical, Inc. (“Sunesis” or the “Company”) is a biopharmaceutical company focused on the development of new targeted inhibitors for the treatment of solid and hematologic cancers. Our primary activities since incorporation have been conducting research and development internally and through corporate collaborators, in-licensing and out-licensing pharmaceutical compounds and technology, conducting clinical trials, and raising capital.
Our lead program is vecabrutinib, a non-covalent inhibitor of Bruton’s Tyrosine Kinase, or BTK. In clinical trials, vecabrutinib has shown activity against both wild type and C481S-mutated BTK, the most common mutation associated with resistance to ibrutinib. Vecabrutinib is being studied in a Phase 1b/2 clinical trial to assess safety and activity in patients with advanced B-cell malignancies after two or more prior therapies, including ibrutinib or another covalent BTK inhibitor where approved for the disease. The Phase 1b portion of the study is a dose escalation component that will proceed to define a maximum tolerated dose and/or a recommended Phase 2 dose. Upon identifying the Phase 2 dose, the Phase 2 portion will further explore clinical activity and safety in disease- and mutation-specific cohorts, including patients with and without BTK C481 mutations.
We are also developing SNS-510, a PDK1 inhibitor licensed from Millennium Pharmaceuticals, Inc., a wholly-owned subsidiary of Takeda Pharmaceutical Company Limited, or Takeda. We acquired from Takeda global commercial rights to several potential first-in class, preclinical inhibitors of the novel target PDK1, including SNS-510. We are currently characterizing SNS-510 through preclinical pharmacology studies, manufacturing and formulation activities.
We are in a collaboration with Takeda for the development of TAK-580 (formerly MLN2480), an oral pan-RAF inhibitor, which is under investigation for pediatric low-grade glioma.
We are also evaluating strategic alternatives for vosaroxin, a topoisomerase 2 inhibitor for which we conducted a Phase 3 trial in patients with relapsed or refractory acute myeloid leukemia.

Our Strategy
We plan to continue to build Sunesis into a leading biopharmaceutical company focused on the development and commercialization of new targeted oncology therapeutics by:
|
•
|
exploring the safety and efficacy of vecabrutinib as a potential treatment for B-cell malignancies, including for Chronic Lymphocytic Leukemia (“CLL”) patients who have relapsed following treatment with a covalent BTK inhibitor;
|
|
•
|
characterizing SNS-510 through preclinical pharmacology studies, manufacturing and formulation activities; and
|
|
•
|
continuing to expand and develop our oncology-focused pipeline through further licensing or collaboration arrangements and research and development.
|
Development Pipeline
The following chart summarizes our development pipeline:
Vecabrutinib (SNS-062)
Vecabrutinib is a selective, reversible, non-covalent BTK inhibitor. BTK mediates signaling through the B-cell receptor, and is critical for adhesion, migration, proliferation, and survival of normal and malignant B-lineage lymphoid cells. BTK has been well validated as a target for treatment of B-cell malignancies, with the covalent BTK inhibitors Imbruvica® (ibrutinib) and Calquence® (acalabrutinib) approved for relapsed/refractory mantle cell lymphoma, and Imbruvica also approved for newly diagnosed and relapsed/refractory CLL, CLL with 17p deletion, Waldenström’s macroglobulinemia, chronic graft versus host disease (cGVHD), and marginal zone lymphoma. Covalent BTK inhibitors, including Imbruvica and Calquence, form an irreversible bond with cysteine residue 481 (C481) in the BTK kinase domain. This cysteine may mutate to a serine (“C481S”) or another amino acid and this is associated with disease progression and resistance to further treatment with covalent BTK inhibitors. Resistance to covalent BTK inhibitors is a growing problem, with a seminal 2017 paper in the Journal of Clinical Oncology by Woyach et al finding 19% of Imbruvica-treated patients had developed resistance by year 4. Studies, including this one, as well as by the European Research Initiative on CLL (ERIC) and the French Innovative Leukemia Organization (FILO) Group identified the BTK C481S mutation in more than half of Imbruvica-relapsed patients. Collectively these studies provide further evidence of resistance to covalent BTK inhibitors as a significant and growing problem. Vecabrutinib has shown potent inhibitory activity in vitro against both wild type and C481S-mutated BTK and may provide a potential solution to resistance to covalent BTK inhibitors.
In addition to vecabrutinib’s non-covalent inhibition of BTK, vecabrutinib inhibits interleukin-2 inducible kinase (ITK). Inhibition of ITK may improve anti-tumor T-cell activity, and inhibition of both BTK and ITK contributes to Imbruvica’s activity in cGVHD and also the potential improvement in response when combined with chimeric antigen receptor T (CAR-T) cell therapies. Notably, vecabrutinib does not inhibit epidermal growth factor receptor (EGFR), a kinase target associated with skin and gastrointestinal toxicities. Vecabrutinib’s distinct kinase selectivity profile and favorable pharmacokinetics indicate the potential for vecabrutinib to become a differentiated treatment for B-cell malignancies. In 2018, we continued to invest in building vecabrutinib’s nonclinical profile resulting in presentations at the 2018 annual meetings of the European Hematology Association (EHA) and the American Society of Hematology (ASH).
4
In July 2017, we announced the dosing of the first patient in the Phase 1b/2 study, and in connection to this event,
we also made a milestone payment of $2.5 million to Biogen Idec MA, Inc., or Biogen, under the licensing agreement
.
We are studying vecabrutinib in a Phase 1b/2 trial in adults with B-cell malignancies, including relapsed/refractory CLL. The study is now open at 8 leading clinical sites: Dana-Farber Cancer Institute, Weill Cornell Medicine, UC Irvine, MD Anderson Cancer Center, Swedish Cancer Institute, Memorial Sloan Kettering Cancer Center, Moffitt Cancer Center, and University California San Diego. Preliminary safety, pharmacokinetics, and pharmacodynamics from vecabrutinib’s Phase 1b/2 study, as well as some early evidence of clinical activity, were presented at ASH 2018. Specifically, vecabrutinib exposure is sustained throughout the dosing interval, with evidence of pharmacodynamic activity in patients with relapsed/refractory B-cell malignancies. Decreases in pBTK and tumor microenvironment-relevant cytokines were observed in patients with and without BTK C481 mutations. The most common treatment emergent adverse events included anemia, neutropenia, and night sweats. The preliminary safety profile of vecabrutinib is acceptable and dose escalation in the study is continuing. The 100 mg BID cohort opened at the end of 2018.
SNS-510
Our first-in-class PDK1 inhibitor SNS-510 is in preclinical studies.
In January 2014, we in-licensed a series of selective PDK1 inhibitors from Takeda that were discovered under a research collaboration agreement between Biogen and Sunesis, as described below. PDK1 is a key kinase and mediator of PI3K/AKT signaling
and also regulates other pathways, including mitogen-activated protein kinase (MAPK) and NF-KB, by PI3K-independent mechanisms. These pathways are involved in cell growth, differentiation, survival and migration
and are frequently dysregulated in cancers. PDK1 inhibitors are expected to be broadly active in both hematologic and solid tumor malignancies. We have taken a series of PDK1 inhibitors with confirmed antitumor activity in vitro and in vivo into preclinical development, and in 2017, we selected SNS-510 as a development candidate.
There are multiple PI3K pathway inhibitors in late stage development or approval for use in CLL, follicular lymphoma and other malignancies, but no other PDK1 inhibitor approved or in late stage development. We believe SNS-510 is a potential first-in-class compound with demonstrated inhibition of PI3K-dependent and independent pathways and a compelling in vitro and in vivo profile. SNS-510 has the potential for broad-spectrum single agent and combination activity in both solid tumor and hematologic malignancies.
TAK-580 (formerly MLN2480)
This pan-Raf inhibitor program had its origins in a collaboration agreement between Sunesis and Biogen. In March 2011, Biogen’s rights to this program were exclusively assigned to Takeda. The Raf kinases (A-Raf, B-Raf and C-Raf) are key regulators of cell proliferation and survival within the MAPK pathway. Pan-RAF inhibitors such as TAK-580 are able to regulate MAPK pathway activation that are driven by RAF-monomer signaling, such as BRAF V600 mutations, and are uniquely positioned to also inhibit RAF dimer signaling, which can drive cancers with RAS mutations, non-V600 BRAF mutations, and RAF fusions.
In February 2018, an investigator-sponsored trial was initiated evaluating TAK-580 in Pediatric Low-Grade Glioma (PLGG), for which we believe the scientific rationale is compelling. PLGG accounts for nearly 30% of pediatric brain cancer, and Fusion-RAF proteins are present in a large proportion of these pediatric tumors. There is a significant unmet need for these children. The trial is ongoing.
Under the license agreement, we may in the future receive up to $57.5 million in pre-commercialization, event-based payments related to the development by Takeda of the first two indications for each of the licensed products directed against the Raf target, and royalty payments depending on related product sales, as further described below.
Vosaroxin
Vosaroxin is an anti-cancer quinolone derivative that intercalates DNA and inhibits topoisomerase II, an enzyme critical for cell replication, resulting in replication-dependent, site-selective DNA damage, G2 arrest and apoptosis. We licensed worldwide development and commercialization rights to vosaroxin from Sumitomo Dainippon Pharma Co., Ltd. (“Sumitomo”) in 2003. The Phase 3 trial in patients with relapsed or refractory acute myeloid leukemia did not meet its primary endpoint of demonstrating a statistically significant improvement in overall survival.
We filed a marketing authorization application (“MAA”) with the European Medicines Agency (“EMA”) at the end of 2015
and had several interactions with the EMA in early 2017. As a result of these interactions, feedback from our CHMP rapporteurs and our retained regulatory consultants, and an internal assessment, we announced on May 1, 2017 the withdrawal of our MAA. In 2018 we conducted a thorough process with potential business partners to evaluate various development paths for vosaroxin and we continue to evaluate strategic alternatives.

License, Collaboration and Royalty Agreements
Licensing and Collaboration Agreements with Biogen and Takeda
Overview
In August 2004, we entered into the original collaboration agreement with Biogen (the “Biogen OCA”) to discover, develop and commercialize small molecule inhibitors of the human protein Raf kinase, including family members Raf-1, A-Raf, B-Raf and C-Raf, (collectively “Raf”), and up to five additional targets that play a role in oncology and immunology indications such as BTK and PDK1.
In June 2008, the parties agreed to terminate the research term and related funding. In March 2011, as part of a series of agreements among Sunesis, Biogen and Takeda, we entered into: (a) an amended and restated collaboration agreement with Biogen (“the Biogen Idec 1st ARCA”); (b) a license agreement with Millennium (“the Takeda Agreement”); and (c) a termination and transition agreement among Sunesis, Biogen and Takeda (“the Termination and Transition Agreement”).
The Termination and Transition Agreement provided for the termination of Biogen’s exclusive rights under the Biogen OCA to all discovery programs under such agreement other than for small molecule inhibitors of the human protein BTK and the permitted assignment to Takeda of all related Biogen collaboration assets and rights to Raf kinase and the human protein PDK1.
Biogen
In December 2013, we entered into a second amended and restated collaboration agreement with Biogen (the “Biogen 2nd ARCA”), which amended and restated the Biogen 1st ARCA, to provide us with an exclusive worldwide license to develop, manufacture and commercialize vecabrutinib, a BTK inhibitor synthesized under the Biogen 1st ARCA, solely for oncology indications. During the third quarter of 2017, we made a milestone payment of $2.5 million to Biogen upon the dosing of the first patient in a Phase 1b/2 study to assess the safety and activity of vecabrutinib in patients with advanced B-cell malignancies after two or more prior therapies, including ibrutinib or other covalent BTK inhibitors, and including patients with BTK C481 mutations. We may also be required to make royalty payments on product sales of vecabrutinib.
Takeda
Under the Takeda Agreement, we granted exclusive licenses to products against two oncology, Raf and PDK1, under substantially the same terms as under the Biogen OCA.
In January 2014, we entered into an amended and restated license agreement with Takeda (“the Amended Takeda Agreement”), to provide us with an exclusive worldwide license to develop and commercialize preclinical inhibitors of PDK1. In connection with execution of the Amended Takeda Agreement, we paid an upfront fee and may in the future be required to make up to $9.2 million in pre-commercialization milestone payments depending on our development of PDK1 inhibitors and royalty payments depending on related product sales.
With respect to the Raf target, Takeda is developing the oral investigative drug TAK-580, and we may in the future receive up to $57.5 million in pre-commercialization, event-based payments related to the development by Takeda of the first two indications for each of the licensed products directed against the Raf target and royalty payments depending on related product sales. The agreement also provides us with future co-development and co-promotion rights. TAK-580 is currently being studied in a Phase 1b/2 clinical study for children with Low-Grade Gliomas and other RAS/RAF/MEK/ERK Pathway Activated Tumors.
In-license Agreement with Sumitomo
In October 2003, we entered into an agreement with Sumitomo to acquire exclusive worldwide development and marketing rights for vosaroxin. In the future we may be required to make additional milestone payments of up to $6.5 million in aggregate to Sumitomo for (a) filing New Drug Applications (“NDA”), in the U.S. and Japan, and (b) for receiving regulatory approvals in these regions and the EU, for cancer-related indications. If vosaroxin is approved for a non-cancer indication, an additional milestone payment will become payable to Sumitomo. The agreement also provides for royalty payments to Sumitomo at rates based on total annual net sales.
If we discontinue seeking regulatory approval and/or the sale of the product in a region, we are required to return our rights to the product in that region to Sumitomo. The agreement may be terminated by either party for the other party’s uncured breach or bankruptcy.

Manufacturing
We rely on, and we expect to continue to rely on, a limited number of third-party contract manufacturers for the production of clinical and commercial quantities of all of our active pharmaceutical ingredient (“API”), including vecabrutinib, SNS-510 and vosaroxin and the finished drug product (“FDP”) incorporating the APIs. Vecabrutinib API and FDP are manufactured under master services agreements. SNS-510 API and FDP are manufactured under research and development agreements. We have supply agreements for vosaroxin API and FDP.
We currently rely on two contract manufacturers for vecabrutinib API and two for FDP. Three lots of API have been manufactured at a clinical scale. Scale-up to commercial scale has not been done. The cost to manufacture vecabrutinib at large scale is unknown.
Competition
The life sciences industry is highly competitive, and we face significant competition from many pharmaceutical, biopharmaceutical and biotechnology companies that are researching, developing and marketing products designed to address the treatment of cancer, including B-cell malignancies. Many of our competitors have significantly greater financial, manufacturing, marketing and drug development resources than we do. Large pharmaceutical companies in particular have extensive experience in the clinical testing of, obtaining regulatory approvals for, and marketing drugs.
With respect to vecabrutinib, we are aware of a number of companies that are or may be pursuing different product candidates that could inhibit C481S-mutated BTK, including Aptose Biosciences Inc., ArQule, Inc., and Loxo Oncology, Inc. Moreover, numerous companies are also pursuing inhibitors of wild-type BTK, including AbbVie Inc. (“AbbVie”), with its drug IMBRUVICA®. Other companies with BTK inhibitors currently in development include AstraZeneca PLC, BeiGene, Ltd., EMD Merck, Gilead Sciences, Inc. (“Gilead”), Principia Biopharm Inc., and others in oncology and non-oncology indications. Other drugs that may compete to treat ibrutinib-refractory patients, including patients with C481S-mutated BTK in monotherapy or in combination, include; AbbVie’s Bcl-2 inhibitor VENCLEXTA™, Gilead’s Zydelig PI3K kinase inhibitor, TG Therapeutics, Inc.’s umbralisib PI3K inhibitor, Verastem’s duvelisib PI3K inhibitor, and CAR-T cell therapies such as Novartis Kymriah® (tisagenlecleucel) and Gilead’s Yescarta (axicabtagene ciloleucel).
Intellectual Property
We believe that patent protection is very important to our business and that our future success depends in part on our ability to obtain patents protecting vecabrutinib, SNS-510, TAK-580, vosaroxin or future drug candidates, if any. Historically, we have patented a wide range of technology, inventions and improvements related to our business. When appropriate, we seek orphan drug status and/or data exclusivity in the United States and their equivalents in other relevant jurisdictions, to the maximum extent that the respective laws will permit at such time. For example, we secured orphan drug designation for vosaroxin for the treatment of AML from the European Commission and from the FDA. For an approved medicine, such designation may, in the European Union, provide ten years of marketing exclusivity in all member countries, or seven years of market exclusivity in the U.S.

General
While it is possible that patent term restoration and/or supplemental patent certificates could be available for some of these or other patents we own or control through licenses after possible approval of commercial product, we cannot guarantee that such additional protection will be obtained, and the expiration dates described here do not include such term restoration.
Our commercial success depends on our ability to operate without infringing patents and proprietary rights of third parties. We cannot determine with certainty whether patents or patent applications of other parties may materially affect our ability to conduct our business. The existence of third-party patent applications and patents could significantly reduce the coverage of patents owned by or licensed to us and limit our ability to obtain meaningful patent protection. If patents containing competitive or conflicting claims are issued to third parties and these claims are ultimately determined to be valid, we may be enjoined from pursuing research, development or commercialization of vecabrutinib, SNS-510, TAK-580, vosaroxin or future drug candidates, if any, or be required to obtain licenses to such patents or to develop or obtain alternative technology.
We also rely on trade secrets to protect our technology, especially in situations or jurisdictions in which we believe patent protection may not be appropriate or obtainable. However, trade secrets are difficult to maintain and do not protect technology against independent developments made by third parties. We seek to protect our proprietary information by requiring our employees, consultants, contractors and other advisers to execute nondisclosure and assignment of invention agreements upon commencement of their employment or engagement. Agreements with our employees also prevent them from bringing the proprietary rights of third parties to us. We also require confidentiality or material transfer agreements from third parties that receive our confidential data or materials. We seek to protect our company name and the names of our products and technologies by obtaining trademark registrations, as well as common law rights in trademarks and service marks, in the United States and in other countries
.
Government Regulation
The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the clinical development, manufacture, marketing and distribution of drugs. These agencies and other federal, state and local and foreign entities regulate research and development activities and the testing, manufacture, quality control, safety, efficacy, labeling, storage, recordkeeping, approval, advertising and promotion of our product candidates and any future drug candidates we may develop, if any. The application of these regulatory frameworks to the development, approval and commercialization of our drug candidates will take a number of years to accomplish, if at all, and involve the expenditure of substantial resources.
8
In the United States, the FDA re
gulates drugs under the Federal Food, Drug, and Cosmetic A
ct, as amended, and implements
regulations. The process required by the FDA before any of our drug candidates may be marketed in the
U.S.
generally involves the following:
|
•
|
completion of extensive preclinical laboratory tests,
in vivo
preclinical studies and formulation studies;
|
|
•
|
submission to the FDA of an IND application, which must become effective before clinical trials begin;
|
|
•
|
performance of adequate and well-controlled clinical trials to establish the safety and efficacy of the product candidate for each proposed indication;
|
|
•
|
submission of an NDA to the FDA;
|
|
•
|
satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities at which the product candidate is produced to assess compliance with current Good Manufacturing Practice (“cGMP”) regulations; and
|
|
•
|
FDA review and approval of the NDA, including proposed labeling (package insert information) and promotional materials, prior to any commercial marketing, sale or shipment of the drug.
|
The testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that approvals will be granted on a timely basis, if at all.
Preclinical Testing and INDs
Preclinical tests include laboratory evaluation of product chemistry, formulation and stability, as well as studies to evaluate toxicity in animals. Laboratories that comply with the FDA Good Laboratory Practice regulations must conduct preclinical safety tests. The results of preclinical tests, together with manufacturing information and analytical data, are submitted as part of an IND application to the FDA. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions about the conduct of the clinical trial, including concerns that human research subjects will be exposed to unreasonable health risks. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin.
Clinical Trials
Clinical trials involve the administration of an investigational drug to healthy volunteers or to patients under the supervision of a qualified principal investigator. Clinical trials are conducted in accordance with the FDA’s Protection of Human Subjects regulations and Good Clinical Practices (“GCP”), under protocols that detail the objectives of the study, the parameters to be used to monitor safety, and the efficacy criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND application.
In addition, each clinical study must be conducted under the auspices of an independent institutional review board (“IRB”), at each institution where the study will be conducted. Each IRB will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution. The FDA, an IRB, or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Clinical testing also must satisfy extensive GCP requirements and regulations for informed consent.
Clinical trials are typically conducted in three sequential phases, which may overlap, sometimes followed by a fourth phase:
|
•
|
Phase 1 clinical trials
are initially conducted in a limited population to test the drug candidate for safety (adverse effects), dose tolerance, absorption, metabolism, distribution and excretion in healthy humans or, on occasion, in patients, such as cancer patients. In some cases, particularly in cancer trials, a sponsor may decide to conduct what is referred to as a “Phase 1b” evaluation, which is a safety-focused, multiple ascending dose Phase 1 clinical trial, often conducted in patients.
|
|
•
|
Phase 2 clinical trials
are generally conducted in a limited patient population to identify possible adverse effects and safety risks, to determine the efficacy of the drug candidate for specific targeted indications and to determine dose tolerance and optimal dosage. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more expensive Phase 3 clinical trials. In some cases, a sponsor may decide to conduct what is referred to as a “Phase 2b” evaluation, which is a second, confirmatory Phase 2 clinical trial that could, if positive and accepted by the FDA, serve as a pivotal clinical trial in the approval of a drug candidate.
|
9
|
•
|
Phase 3 clinical trials
are commo
nly referred to as pivotal trials. When Phase 2 clinical trials demonstrate that a drug candidate has potential activity in a disease or condition and has an acceptable safety profile, Phase 3 clinical trials are undertaken to further evaluate clinical eff
icacy and to further test for safety in an expanded patient population at multiple, geographically dispersed clinical trial sites.
|
|
•
|
Phase 4 (post-marketing) clinical trials
may be required by the FDA in some cases. The FDA may conditionally approve an NDA for a drug candidate on a sponsor’s agreement to conduct additional clinical trials to further assess the drug’s safety and/or efficacy after NDA approval. Such post-approval trials are typically referred to as Phase 4 clinical trials.
|
New Drug Applications
Assuming successful completion of the required clinical testing, the results of the preclinical studies and clinical trials, together with detailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as part of an NDA requesting approval to market the product for one or more indications. Under federal law, the submission of most NDAs is additionally subject to a substantial application fee under the Prescription Drug User Fee Act (“PDUFA”), and the sponsor of an approved NDA is also subject to annual program fees, which are typically increased annually.
The FDA conducts a preliminary review of all NDAs within the first 60 days after submission before accepting them for filing to determine whether they are sufficiently complete to permit substantive review. The FDA may request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA has agreed to specified performance goals in the review of NDAs. Under these goals, the FDA has committed to review most such applications for non-priority products within 10 months of filing, and most applications for priority review products, that is, drugs that the FDA determines represent a significant improvement over existing therapy, within six months of filing. The review process may be extended by the FDA for three additional months to consider certain information or clarification regarding information already provided in the submission. The FDA may also refer applications for novel drugs or 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 as to whether the application should be approved. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.
Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. In addition, before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP and integrity of the clinical data submitted.
The testing and approval process requires substantial time, effort and financial resources, and each may take many years to complete. Data obtained from clinical activities are not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. The FDA may not grant approval on a timely basis, or at all. We may encounter difficulties or unanticipated costs in our efforts to develop our product candidates and secure necessary governmental approvals, which could delay or preclude us from marketing our products.
After the FDA’s evaluation of the NDA and inspection of the manufacturing facilities, the FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. A complete response letter 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 and 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. Even with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval and refuse to approve the NDA. Even if the FDA approves a product, it may limit the approved indications for use for the product, require that contraindications, warnings or precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms, including Risk Evaluation and Mitigation Strategies, or REMs, which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post-market studies or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and approval.

Orphan Drug Designation
The United States Orphan Drug Act promotes the development of products that demonstrate promise for the diagnosis and treatment of diseases or conditions that affect fewer than 200,000 people in the United States. Upon receipt of orphan drug designation from the FDA, the sponsor is eligible for tax credits for qualified clinical trial expenses, the ability to apply for annual grant funding, waiver of PDUFA application fee, and upon approval, the potential for seven years of market exclusivity for the orphan-designated product for the orphan-designated indication. On December 22, 2017, the 2017 Tax Cuts and Jobs Act (the Tax Act) was enacted into law and the Orphan Drug tax credit was reduced from 50% to 25%. In October 2009, the FDA granted orphan drug designation to vosaroxin for treatment of AML.
In the European Union, orphan status is available for therapies addressing conditions that affect five or fewer out of 10,000 people, and provides for the potential for 10 years of marketing exclusivity in Europe for the orphan-designated product for the orphan-designated indication. The marketing exclusivity period can be reduced to six years if, at the end of the fifth year, available evidence establishes that the product is sufficiently profitable not to justify maintenance of market exclusivity. In April 2012, the European Commission granted orphan drug designation to vosaroxin for the treatment of AML.
Other Regulatory Requirements
Any drugs manufactured or distributed by us, Biogen, Takeda, or our potential future licensees or collaboration partners, if any, pursuant to FDA approvals are subject to continuing regulation by the FDA, including recordkeeping requirements and reporting of adverse experiences associated with the drug. Drug manufacturers and their subcontractors are required to register with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with ongoing regulatory requirements, including cGMPs, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Failure to comply with the statutory and regulatory requirements can subject a manufacturer to possible legal or regulatory action, such as warning letters, suspension of manufacturing, seizure of product, injunctive action or possible civil penalties.
The FDA closely regulates the post-approval marketing and promotion of drugs, including standards and regulations for direct-to-consumer advertising, off-label promotion, industry-sponsored scientific and educational activities and promotional activities involving the Internet. A company can make only those claims relating to safety and efficacy that are approved by the FDA. Physicians may prescribe legally available drugs for uses that are not described in the drug’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties, including cancer therapy. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, impose stringent restrictions on manufacturers’ communications regarding off-label use. Failure to comply with these requirements can result in adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties.
Healthcare Law and Regulation
In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal laws restrict our business activities, including certain marketing practices. These laws include, without limitation, anti-kickback laws, false claims laws, data privacy and security laws, as well as transparency laws regarding payments or other items of value provided to healthcare providers.
The federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce or in return for either the referral of an individual, or the purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item, good, facility or service reimbursable under Medicare, Medicaid or other federal healthcare programs.
Federal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, prohibit any person or entity from, among other things, knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to be made, a false statement to have a false claim paid.
The federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), created new federal criminal statutes that prohibit among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), and its implementing regulations, imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s security standards directly applicable to business associates, independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity.
11
Additionally, the federal Physician Payments Sunshine Act, created under the
Affordable Care Act
(“
ACA
”)
, and its implementing regulations, require certa
in 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 annually report to the Centers for Medicare & Medicaid Serv
ices (“CMS”), information related to certain payments or other transfers of value provided to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals and to repor
t annually certain ownership and investment interests held by physicians and their immediate family members.
The majority of states also have statutes or regulations similar to the aforementioned federal laws, some of which are broader in scope and apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. State and foreign laws also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. These laws may affect our sales, marketing and other promotional activities by imposing administrative and compliance burdens.
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the health regulatory laws described above or any other laws that apply to us, we may be subject to a wide range of sanctions and penalties, potentially significant criminal and civil and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, integrity obligations, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. We are unable to predict whether we would be subject to actions under these laws or the impact of such actions. However, the cost of defending any such claims, as well as any sanctions imposed, could adversely affect our financial performance and disrupt our business operations.
Coverage and Reimbursement
Sales of pharmaceutical products, when and if approved for marketing, depend significantly on the availability of third-party coverage and adequate reimbursement. Third-party payors include government health administrative authorities, managed care providers, private health insurers and other organizations. These third-party payors are increasingly challenging the price and examining the cost-effectiveness of medical products and services, and significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. A payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a drug product does not assure that other payors will also provide coverage for the drug product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.
In addition, significant uncertainty exists as to the coverage and reimbursement status of newly approved healthcare products. We may need to conduct expensive clinical studies to demonstrate the comparative cost-effectiveness of our products. The product candidates that we develop may not be considered cost-effective. It is time consuming and expensive for us to seek reimbursement from third-party payors. Decreases in third-party reimbursement for our product candidates or a decision by a third-party payor not to cover our product candidates could reduce physician usage of our products once approved and have a material adverse effect on our sales, results of operations and financial condition. Coverage and adequate reimbursement may not be available or sufficient to allow us to sell our products on a competitive and profitable basis. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.
Health Reform
The United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives, such as the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the ACA. Among the provisions of the ACA of importance to our business are that it: created an annual fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents; increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program; extended a manufacturer’s Medicaid rebate liability; expanded eligibility criteria for Medicaid programs; and created a new Medicare Part D coverage gap discount program. Some of the provisions of the ACA have yet to be implemented, and there have been judicial and Congressional challenges to certain aspects of the ACA, as well as recent efforts
12
by the Trump administration to repeal or replace certain aspects of the ACA.
Since January
2017, President Trump signe
d two Executive Orders and other directives to delay the implementation o
f certain provisions of the ACA
.
Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed
comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA such as removing penalties, starting January 1, 2019, for not complying with the ACA’s individual mandate to carry health insurance and delaying the implementat
ion of certain ACA-mandated fees. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act of 2017. The Tex
as U.S. District Court Judge, as well as the Trump administration and CMS, have stated that the ruling will have no immediate effect pending appeal of the decision.
Other legislative changes have been proposed and adopted since the ACA was enacted. These changes included the Budget Control Act of 2011, which caused aggregate reductions to Medicare payments to providers of up to 2% per fiscal year effective April 1, 2013 which, following passage of the Bipartisan Budget Act of 2015, as well as other legislative amendments to the statute, will stay in effect through 2027 unless additional Congressional action is taken. Additionally, the American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several types of providers.
There has also been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. For example, at the federal level, the Trump administration released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out of pocket costs of drug products paid by consumers. On January 31, 2019, the HHS Office of Inspector General proposed modifications to the federal Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products to consumers which, among other things, if finalized, will affect discounts paid by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit managers working with these organizations. While some of these and other proposed measures may require authorization through additional legislation to become effective, Congress and the Trump administration have each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs.
Additionally, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina Right to Try Act of 2017, or the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase I clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.
Foreign Regulation
In addition to regulations in the U.S., we are subject to foreign regulations governing clinical trials and commercial sales and distribution of or our drug candidates. Whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.
Under European Union regulatory systems, permission to conduct clinical research is granted by the Competent Authority of each European Member State (“MS”), and the applicable Ethics Committees (“EC”), through the submission of a Clinical Trial Application. An EC in the European Union serves the same function as an IRB in the United States. The review times vary by MS but may not exceed 60 days. The EC has a maximum of 60 days to give its opinion on the acceptability of the Clinical Trial Application to both the governing MS and the sponsor applicant. If the application is deemed acceptable, the MS informs the applicant (or does not within the 60-day window inform the applicant of non-acceptance) and we may proceed with the clinical trial.
To obtain a marketing authorization of a drug in the European Union, we must submit an MAA under the centralized procedure. The centralized procedure provides for the grant of a single marketing authorization from the European Commission following a favorable opinion by the CHMP of the EMA that is valid in the European Economic Area (the “EEA”), which includes all European Union member states, as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for medicines produced by specified biotechnological processes, products designated as orphan medicinal products, advanced therapy medicinal products and products with a new active substance indicated for the treatment of specified diseases. Under the centralized procedure the maximum timeframe for the evaluation of an MAA by the EMA is 210 days, excluding clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the CHMP.
13
In the EEA, the EMA’s Committee for Orphan Medicinal Products grants orphan drug designation to promote the development of products that are intended for the diagnosis, prevention or treatme
nt of life-threatening or chronically debilitating conditions affecting not more than five in 10,000 persons in the European Union and for which no satisfactory method of diagnosis, prevention, or treatment has been authorized (or the product would be a si
gnificant benefit to those affected). Additionally, designation is granted for products intended for the diagnosis, prevention, or treatment of a life-threatening, seriously debilitating or serious and chronic condition and when, without incentives, it is
unlikely that sales of the drug in the European Union would be sufficient to justify the necessary investment in developing the medicinal product. A European Union orphan drug designation entitles a party to financial incentives such as reduction of fees o
r fee waivers and 10 years of market exclusivity is granted following medicinal product approval. This period may be reduced to six years if the orphan drug designation criteria are no longer met, including where it is shown that the product is sufficientl
y profitable not to justify maintenance of market exclusivity. Orphan drug designation must be requested before submitting an application for marketing approval. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regu
latory review and approval process.
In the EEA, marketing authorization applications for new medicinal products not authorized have to include the results of studies conducted in the pediatric population, in compliance with a pediatric investigation plan (“PIP”), agreed with the EMA’s Pediatric Committee (“PDCO”). The PIP sets out the timing and measures proposed to generate data to support a pediatric indication of the drug for which marketing authorization is being sought. The PDCO can grant a deferral of the obligation to implement some or all of the measures of the PIP until there are sufficient data to demonstrate the efficacy and safety of the product in adults. Further, the obligation to provide pediatric clinical trial data can be waived by the PDCO when these data is not needed or appropriate because the product is likely to be ineffective or unsafe in children, the disease or condition for which the product is intended occurs only in adult populations, or when the product does not represent a significant therapeutic benefit over existing treatments for pediatric patients. Once a marketing authorization is obtained for a pediatric indication in all Member States of the European Union and study results are included in the product information, even when negative, the product is eligible for six months’ supplementary protection certificate extension. For orphan-designated medicinal products, the 10-year period of market exclusivity is extended to 12 years.
In addition to regulations in the United States and the European Union, we will be subject to a variety of other foreign regulations governing clinical trials and commercial distribution of our product candidates. Our ability to sell drugs will also depend on the availability of reimbursement from government and private insurance companies.
Research and Development Expenses
We expect to continue to incur significant development expenses related to the development of vecabrutinib and our other drug candidates.
Environment
We have made, and will continue to make, expenditures for environmental compliance and protection. We do not expect that such expenditures will have a material effect on our capital expenditures or results of operations in the foreseeable future.
Employees
As of December 31, 2018, our workforce consisted of 29 full-time equivalent employees, of which 15 are engaged in research and development and 14 are engaged in general and administrative, medical affairs and commercial planning functions. We have no collective bargaining agreements with our employees, and we have not experienced any work stoppages.

Please see “Special Note Regarding Forward-Looking Statements.”
Risks Related to Our Business
We need to raise substantial additional funding to continue the development of vecabrutinib, SNS-510, and our other programs.
We will need to raise substantial additional capital to:
|
•
|
fund additional nonclinical and clinical trials of vecabrutinib prior to any regulatory filing for approval;
|
|
•
|
fund preclinical and clinical development of SNS-510;
|
|
•
|
expand our development activities;
|
|
•
|
implement additional internal systems and infrastructure; and
|
|
•
|
build or access commercialization and additional manufacturing capabilities and supplies.
|
Our future funding requirements and sources will depend on many factors, including but not limited to the:
|
•
|
rate of progress and cost of our clinical trials;
|
|
•
|
need for additional or expanded clinical trials;
|
|
•
|
timing, economic and other terms of any licensing, collaboration or other similar arrangement into which we may enter;
|
|
•
|
costs and timing of seeking and obtaining EMA, FDA or other regulatory approvals;
|
|
•
|
extent of our other development activities, including our other clinical programs and in-license agreements;
|
|
•
|
costs associated with building or accessing commercialization and additional manufacturing capabilities and supplies;
|
|
•
|
costs of acquiring or investing in businesses, product candidates and technologies, if any;
|
|
•
|
costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
|
|
•
|
effect of competing technological and market developments;
|
|
•
|
costs of supporting our arrangements with Biogen, Takeda or any potential future licensees or partners.
|
Until we can generate a sufficient amount of licensing, collaboration or product revenue to finance our cash requirements, which we may never do, we expect to finance future cash needs primarily through equity issuances, debt arrangements, one or more possible licenses, collaborations or other similar arrangements with respect to development and/or commercialization rights to vecabrutinib, SNS-510, or our other development programs, or a combination of the above. Any issuance of convertible debt securities, preferred stock or common stock may be at a discount from the then-current trading price of our common stock. If we issue additional common or preferred stock or securities convertible into common or preferred stock, our stockholders will experience additional dilution, which may be significant. Further, we do not know whether additional funding will be available on acceptable terms, or at all. If we are unable to raise substantial additional funding on acceptable terms, or at all, we will be forced to delay or reduce the scope of our vecabrutinib, SNS-510 or other development programs.
15
We have incurred losses since inception and anticipate that we will continue to incur los
ses for the foreseeable future. We may not ever achieve or sustain profitability.
We are not profitable and have incurred losses in each year since our inception in 1998. Our net losses for the years ended December 31, 2018 and 2017 were $26.6 million and $35.5 million, respectively. As of December 31, 2018, we had an accumulated deficit of $659.5 million. We do not currently have any products that have been approved for marketing, and we expect to incur significant losses for the foreseeable future as we continue to incur substantial development and general and administrative expenses related to our operations. We have prioritized development funding on kinase inhibitors with a focus on vecabrutinib. We have a limited number of products that are still in the early stages of development and will require significant additional investment. Our losses, among other things, have caused and will continue to cause our stockholders’ equity and working capital to decrease.
To date, we have derived substantially all of our revenue from license and collaboration agreements. We currently have one agreement, the Amended Takeda Agreement, which includes certain pre-commercialization event-based and royalty payments. We cannot predict if our collaborator will continue development or whether we will receive any such payments under these agreements in the foreseeable future, or at all.
We are unable to predict when we will generate revenue from the sale of products, if at all. In the absence of additional sources of capital or partnering opportunity, which may not be available to us on acceptable terms, or at all, the development of vecabrutinib or future product candidates may be reduced in scope, delayed or terminated. If our product candidates or those of our collaborators fail in clinical trials or do not gain regulatory approval, or if our future products do not achieve market acceptance, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods.
There is substantial
doubt about our ability to continue as a going concern.
We adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40) effective December 31, 2016, which requires us to make certain disclosures if we conclude that there is substantial doubt about our ability to continue as a going concern within one year from the date our financial statements contained in this Annual Report on Form 10-K are available to be issued.
We have incurred significant losses and negative cash flows from operations since our inception, and as of December 31, 2018, had cash and cash equivalents totaling $13.7 million and an accumulated deficit of $659.5 million. We expect our cash and cash equivalents of $13.7 million plus the approximately $18.4 million from the public offering in January 2019, are not sufficient to support our operations for a period of twelve months from the date our financial statements contained in this Annual Report on Form 10-K are available to be issued. We will require additional financing to fund working capital, repay debt and pay our obligations as they come due. Additional financing might include one or more offerings and one or more of a combination of equity securities, debt arrangements or partnership or licensing collaborations. However, there can be no assurance that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms favorable to us. These conditions raise substantial doubt about our ability to continue as a going concern for a period of one year from the date our financial statements contained in this Annual Report on Form 10-K are available to be issued. If we are unsuccessful in our efforts to raise additional financing in the near term, we will be required to significantly reduce or cease operations. The accompanying financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts of liabilities that may result from uncertainty related to our ability to continue as a going concern.
The development of vecabrutinib, SNS-510, or other product candidates could be halted or significantly delayed for various reasons; our clinical trials for vecabrutinib, SNS-510, or other product candidates may not lead to regulatory approval.
Our product candidates are vulnerable to the risks of failure inherent in the drug development process. Failure can occur at any stage of the development process, and successful preclinical studies and early clinical trials do not ensure that later clinical trials will be successful. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier trials.
Our product candidates may experience toxicities that lead to a maximum tolerated dose that is not effective. If this were the case for vecabrutinib, for example, such a result would delay or prevent further development, which would severely and adversely affect our financial results, business and business prospects.
16
We do not know whether
our current or
any future clinical trials with
vecab
rutinib,
SNS
-510
, or any of our product candidates will be completed on schedule, or at all, or whether our ongoing or planned clinical trials will begin or progress on the time schedule we anticipate. The commencement
and completion
of future clinical tri
als could be substantially delayed or prevented by several factors, including:
|
•
|
delays or failures to raise additional funding;
|
|
•
|
delays or failures in obtaining regulatory approval to commence a clinical trial;
|
|
•
|
delays or failures in obtaining approval from independent IRBs or ECs to conduct a clinical trial at prospective sites; or
|
|
•
|
delays or failures in reaching acceptable clinical trial agreement terms or clinical trial protocols with prospective sites.
|
|
•
|
delays or failures in obtaining sufficient clinical materials, including any of our product and any drugs to be tested in combination with our products;
|
|
•
|
failure of third parties such as Contract Research Organizations and medical institutions to perform their contractual duties and obligations;
|
|
•
|
slower than expected rates of patient recruitment and enrollment;
|
|
•
|
failure of patients to complete the clinical trial;
|
|
•
|
delays or failures in reaching the number of events pre-specified in the trial design;
|
|
•
|
the need to expand the clinical trial;
|
|
•
|
unforeseen safety issues;
|
|
•
|
lack of efficacy during clinical trials;
|
|
•
|
inability or unwillingness of patients or clinical investigators to follow our clinical trial protocols; and
|
|
•
|
inability to monitor patients adequately during or after treatment.
|
Additionally, our clinical trials may be suspended or terminated at any time by the FDA, other regulatory authorities, or ourselves for reasons such as change in protocol. Any failure to complete or significant delay in completing clinical trials for our product candidates could harm our financial results and the commercial prospects for our product candidates.
We rely on a limited number of third parties to supply us with our API and FDP. If we fail to obtain sufficient quantities of these materials, the development and potential commercialization of vecabrutinib, SNS-510 and future products, if any, could be halted or significantly delayed.
We currently rely on contract manufacturers for all API and FDP. Additional third-party contract manufacturing organizations are relied on to manufacture key starting materials and intermediates required in the manufacture of API. We have limited manufacturing experience, and we have not yet scaled-up to commercial scale. The cost to manufacture at commercial scale may materially exceed the cost of clinical-stage manufacturing.
If our third-party API or FDP manufacturers are unable or unwilling to produce the API or FDP we require, we would need to establish arrangements with one or more alternative suppliers. However, establishing a relationship with an alternative supplier would likely delay our ability to produce API or FDP. Our ability to replace an existing manufacturer would also be difficult and time consuming because the number of potential manufacturers is limited and the FDA, EMA or other corresponding state agencies must approve any replacement manufacturer before it can be an approved commercial supplier. Such approval would require new testing, stability programs and compliance inspections. It may be difficult or impossible for us to identify and engage a replacement manufacturer on acceptable terms in a timely manner, or at all. We expect to continue to depend on third-party contract manufacturers for all our API and FDP needs for the foreseeable future.
Our products require precise, high quality manufacturing. In addition to process impurities, the failure of our contract manufacturers to achieve and maintain high manufacturing standards in compliance with cGMP regulations could result in other manufacturing errors leading to patient injury or death, product recalls or withdrawals, delays or interruptions of production or failures in product testing or delivery. Although contract manufacturers are subject to ongoing periodic unannounced inspection by the FDA, EMA or other corresponding state agencies to ensure strict compliance with cGMP and other applicable government regulations and corresponding foreign standards, any such performance failures on the part of a contract manufacturer could result in the delay or prevention of filing or approval of marketing applications for our products, cost overruns or other problems that could seriously harm our business. This would deprive us of potential product revenue and result in additional losses.

is also a key risk, as we must demonstrate that products continue to meet
product
specifications over time
. Ther
e can be no assurances that future lots will meet stability requirements and if
they do
not,
development and commercialization of our products
may be delayed.
The failure to enroll patients for clinical trials may cause delays in developing vecabrutinib or other product candidates.
We may encounter delays if we are unable to enroll enough patients to complete clinical trials of vecabrutinib or other product candidates. Patient enrollment depends on many factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites, the number and nature of competing treatments and ongoing clinical trials of competing drugs for the same indication, and the eligibility criteria for the trial. In a Phase 1 dose escalation, slots are assigned to sites to avoid over-enrolling. After allocating a slot to a patient, patients may be unable to commence the study due to progressive disease or may withdraw consent. Patients participating in our trials may come off study due to progressive disease, or may elect to leave our trials to switch to alternative treatments that are available to them, either commercially or on an expanded access basis, or in other clinical trials.
The results of preclinical studies and clinical trials may not satisfy the requirements of the FDA, EMA or other regulatory agencies.
Prior to receiving approval to commercialize vecabrutinib, SNS-510, or future product candidates in Europe, the United States or in other territories, we must demonstrate with substantial evidence from well-controlled clinical trials, to the satisfaction of the FDA, EMA and other regulatory authorities, that such product candidates are safe and effective for their intended uses. The results from preclinical studies and clinical trials can be interpreted in different ways. Even if we believe preclinical or clinical data from preclinical studies and clinical trials are promising, such data may not be sufficient to support approval by the FDA, EMA and other regulatory authorities
.
Results in preclinical studies may not be predictive of results in human clinical trials and early stage human clinical trials may not be predictive of results in later, larger trials.
Our product candidates, the methods used to deliver them or their dosage levels may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label or result in significant negative consequences following any regulatory approval.
Undesirable side effects caused by our product candidates, their delivery methods or dosage levels 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 authority. As a result of safety or toxicity issues that we may experience in our clinical trials, we may not receive approval to market any product candidates, which could prevent us from ever generating revenues or achieving profitability. Results of our trials could reveal an unacceptably high severity and incidence of side effects, or side effects outweighing the benefits of our product candidates. In such an event, our trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled subjects to complete the trial or result in potential product liability claims.
Additionally, if any of our product candidates receives regulatory approval, and we or others later identify undesirable side effects caused by such product, a number of potentially significant negative consequences could result, including that:
|
•
|
we may be forced to suspend marketing of that product;
|
|
•
|
regulatory authorities may withdraw or change their approvals of that product;
|
|
•
|
regulatory authorities may require additional warnings on the label or limit access of that product to selective specialized centers with additional safety reporting and with requirements that patients be geographically close to these centers for all or part of their treatment;
|
|
•
|
we may be required to conduct post-marketing studies;
|
|
•
|
we may be required to change the way the product is administered;
|
|
•
|
we could be sued and held liable for harm caused to subjects or patients; and
|
|
•
|
our reputation may suffer.
|
18
An
y of these events could diminish the usage or otherwise limit the commercial success of our product candidates and prevent us from achieving or maintaining market acceptance of the affected product candidate, if approved by applicable regulatory authoritie
s.
We may not be able to obtain or maintain orphan drug exclusivity for our product candidates.
Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States. Both the FDA and the EMA have granted us orphan designation for
vosaroxin
.
Generally, if a product with an orphan drug designation subsequently receives the first regulatory approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the EMA or the FDA from approving another marketing application for the same drug for that time period. The applicable period is seven years in the United States and ten years in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition.
Even if we obtain orphan drug exclusivity for a product, that exclusivity may not be maintained or effectively protect the product from competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve a new drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.
We rely on third parties to conduct our clinical trials. If these third parties do not successfully carry out their contractual duties or fail to meet expected deadlines, we may be unable to obtain regulatory approval for, or commercialize, vecabrutinib or other product candidates.
We rely on third parties, such as contract research organizations, medical institutions, clinical investigators and contract laboratories, to conduct our planned and existing clinical trials for vecabrutinib and other product candidates. If the third parties conducting our clinical trials do not perform their contractual duties or obligations, do not meet expected deadlines or need to be replaced, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical trial protocols or for any other reason, we may need to enter into new arrangements with alternative third parties and our clinical trials may be extended, delayed or terminated or may need to be repeated, and we may not be able to obtain regulatory approval for or commercialize the product candidate being tested in such trials.
We may expand our development capabilities in the future, and any difficulties hiring or retaining key personnel or managing this growth could disrupt our operations.
We are highly dependent on the principal members of our development staff. We may expand our research and development capabilities in the future by increasing expenditures in these areas, hiring additional employees and potentially expanding the scope of our current operations. Future growth will require us to continue to implement and improve our managerial, operational and financial systems and continue to retain, recruit and train additional qualified personnel, which may impose a strain on our administrative and operational infrastructure. The competition for qualified personnel in the biopharmaceutical field is intense. We are highly dependent on our continued ability to attract, retain and motivate highly qualified management and specialized personnel required for clinical development. Due to our limited resources, we may not be able to effectively manage any expansion of our operations or recruit and train additional qualified personnel. If we are unable to retain key personnel or manage our growth effectively, we may not be able to implement our business plan.
19
If we are sued for infringing intellectual property rights of third parties, litigation will be costly and time consuming and could prevent us from developing or comm
ercializing
vecabrutinib,
SNS-
510
, or other product candidates.
Our commercial success depends on not infringing the patents and other proprietary rights of third parties and not breaching any collaboration or other agreements we have entered into with regard to our technologies and product candidates. If a third party asserts that we, our licensors, collaboration partners, or any employees thereof have misappropriated their intellectual property, or otherwise claim that we, our licensors, or collaboration partners are using technology claimed in issued and unexpired patents, or other proprietary rights, owned or controlled by the third party, even if the technology is regarded as our own intellectual property, we may need to obtain a license, enter into litigation to challenge the validity or enforceability of the patents or other rights or incur the risk of litigation in the event that a third party asserts that we infringe its patents or have misappropriated other rights.
If a third party asserts that we infringe its patents or other proprietary rights, we could face a number of challenges that could seriously harm our competitive position, including:
|
•
|
infringement and other intellectual property claims, which would be costly and time consuming to litigate, whether or not the claims have merit, and which could delay the regulatory approval process and divert management’s attention from our business;
|
|
•
|
substantial damages for past infringement, which we may have to pay if a court determines that vecabrutinib, SNS-510, or any future product candidates infringe a third party’s patent or other proprietary rights;
|
|
•
|
a court order prohibiting us from selling or licensing vecabrutinib, SNS-510, or any future product candidates unless a third party licenses relevant patent or other proprietary rights to us, which it is not required to do; and
|
|
•
|
if a license is available from a third-party, we may have to pay substantial royalties or grant cross-licenses to our patents or other proprietary rights.
|
If our competitors develop and market products that are more effective, safer or less expensive than vecabrutinib, vosaroxin or other product candidates, our commercial opportunities will be negatively impacted.
The life sciences industry is highly competitive, and we face significant competition from many pharmaceutical, biopharmaceutical and biotechnology companies that are researching, developing and marketing products designed to address the treatment of cancer, including B-cell malignancies and AML. Many of our competitors have significantly greater financial, manufacturing, marketing and drug development resources than we do. Large pharmaceutical companies in particular have extensive experience in the clinical testing of, obtaining regulatory approvals for, and marketing drugs.
We expect competition during the development and commercialization of all of our products in all of their potential future indications. Competition is likely to increase as additional products are developed and approved in various patient populations. If our competitors market products that are more effective, safer, and/or less expensive than our future products, if any, or that reach the market sooner we may not achieve commercial success or substantial market penetration. In addition, the biopharmaceutical industry is characterized by rapid change. Products developed by our competitors may render any of our future product candidates obsolete.
Our proprietary rights may not adequately protect vecabrutinib, SNS-510, or future product candidates, if any.
We use patents, trade secrets, trademarks, service marks, and marketing exclusivity administered by regulatory authorities to protect our products from generic copies of our products. Our ability to build and maintain our proprietary position for any future drug candidates will depend on our success in obtaining effective patent claims and enforcing granted claims. The patent positions of biopharmaceutical companies like ours are generally uncertain and involve complex legal and factual questions for which some important legal principles remain unresolved. No consistent policy regarding the breadth of patent claims has emerged to date in the United States. The patent situation outside the United States is even more uncertain. We do not know whether any of our patent applications or those patent applications that we license will result in the issuance of any patents. Even if patents are issued, they may not be sufficient to protect vecabrutinib, SNS-510, or other product candidates. The patents we own or license and those that may be issued in the future may be opposed, challenged, invalidated or circumvented, and the rights granted under any issued patents may not provide us with proprietary protection or competitive advantages.
20
We
apply for patents covering both our technologies and product candidates, as we deem appropriate. However, we may fail to apply for patents on important technologies or product candidate
s in a timely fashion, throughout the world, or at all. Our existing patents and any future patents we obtain may not be sufficiently broad, valid, enforceable, or extend globally in order to prevent others from practicing our technologies or from developi
ng competing products and technologies. Further, obtaining and maintaining patent protection relies on compliance with various procedural requirements imposed by governmental patent agencies, including, for example, mandatory document submissions and fee p
ayments. Failure to comply with these requirements may reduce or eliminate opportunities for, or rights to, patent protection. In addition, we generally do not exclusively control the patent prosecution of subject matter that we license to or from others.
Accordingly, in such cases we are unable to exercise the same degree of control over this intellectual property as we would over our own. Similarly, we do not exclusively control patent prosecution in jurisdictions outside of the United States. Moreover, t
he patent positions of biopharmaceutical companies are highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. As a result, the scope, validity and enforceability of patents in addition to th
e related cost, can vary from country to country, and can change depending on changes in national and international law, and as such, cannot be predicted with certainty. In addition, we do not know
whether:
|
•
|
we, our licensors or our collaboration partners were the first to make the inventions covered by each of our issued patents and pending patent applications;
|
|
•
|
we, our licensors or our collaboration partners were the first to file patent applications for these inventions;
|
|
•
|
others will independently develop similar or alternative technologies or duplicate any of our technologies;
|
|
•
|
any of our, our licensors’ or our collaboration partners’ pending patent applications will result in issued patents;
|
|
•
|
any of our, our licensors’ or our collaboration partners’ patents will be valid or enforceable;
|
|
•
|
because of differences in patent laws of countries, any patent granted in one country or region will be granted in another, or, if so, have the same or a different scope;
|
|
•
|
any patents issued to us, our licensors or our collaboration partners will provide us with any competitive advantages, or will be challenged by third parties;
|
|
•
|
we will develop additional proprietary technologies that are patentable;
|
|
•
|
we, our licensors, or our collaboration partners will be subject to claims challenging the inventorship, ownership, or rights to claim priority with regard to our patents and other intellectual property; or
|
|
•
|
any patents or other proprietary rights of third parties will have an adverse effect on our business.
|
We may need to commence or defend administrative proceedings or litigation to enforce or to determine the scope and validity of any patents issued to us or to determine the scope and validity of third party proprietary rights. Litigation would result in substantial costs, even if the eventual outcome is favorable to us. An adverse outcome in a proceeding or litigation affecting proprietary rights we own or have licensed could present significant risk of competition for drug candidates that we market or seek to develop. Any adverse outcome in a proceeding or litigation affecting third party proprietary rights could subject us to significant liabilities to third parties and could require us to seek licenses of the disputed rights from third parties or to cease using the technology if such licenses are unavailable.
There can be no assurance that the trademarks or service marks we use or register will protect our company name or any products or technologies that we develop and commercialize, that our trademarks, service marks, or trademark registrations will be enforceable against third parties, or that our trademarks and service marks will not interfere with or infringe trademark rights of third parties. We may need to commence litigation to enforce our trademarks and service marks or to determine the scope and validity of our or a third party’s trademark rights. Litigation would result in substantial costs, even if the eventual outcome is favorable to us. An adverse outcome in litigation could subject us to significant liabilities to third parties and require us to seek licenses of the disputed rights from third parties or to cease using the trademarks or service marks if such licenses are unavailable.
We also rely on trade secrets to protect some of our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to maintain and enforce. While we use reasonable efforts to protect our trade secrets, our or our collaboration partners’ employees, consultants, contractors or scientific and other advisors, or those of our licensors or collaborators, may unintentionally or willfully disclose our proprietary information to competitors. Enforcement of claims that a third party has illegally obtained and is using trade secrets is expensive, time consuming and uncertain. In addition, foreign courts are sometimes less willing than U.S. courts to protect trade secrets. If our competitors independently develop equivalent knowledge, methods and know-how, we would not be able to assert our trade secret protection against them and our business could be harmed.
21
There can be no assurance that the confidentiality and other agreements we put in place with employees, consultants, and partners will provide meaningful protection, that these agreements will not be breached, that we will have an adequate remedy for any s
uch breach, or that our trade secrets will not otherwise become known or independently developed by a third party.
We do not know whether the patent term for any drug candidate or product will offer protection for an adequate or profitable amount of time. We do not know whether patent term extensions and data exclusivity periods will be available in the future for any or all of the patent rights we own or have licensed. While it is possible that patent term restoration and/or supplemental patent certificates would be available for some of the patents we own or control through licenses, we cannot guarantee that such additional protection will be obtained, and the expiration dates described here do not include such term restoration. However, patent expiration dates described here for U.S. patents may reflect patent term adjustments by the United States Patent and Trademark Office or terminal disclaimers over related patents or patent applications. Our obligation to pay royalties to licensors may extend beyond the patent expiration, which would further erode the profitability of our products.
Intellectual property rights may not address all potential threats to our competitive position for at least the reasons described above and below.
We may not succeed in finding a third party to license and complete development of vosaroxin, which may result in completely discontinuing development and returning rights to our licensor, Sumitomo Dainippon.
We are actively evaluating strategic alternatives, including seeking a partner to license vosaroxin for the purpose of completing development and commercializing the product. There is no certainty that we will find a commercial or financial partner to fund and undertake development, and failure to find such a partner will result in the complete discontinuation of vosaroxin development. In this case, the core IP will revert to Sumitomo Dainippon Pharma Co., Ltd. and there will be no possibility of any future upside from the product. We may also incur costs to wind down all of our activities related to this product.
Even if we do secure a partner for vosaroxin, there is no guarantee the transaction will result in significant revenue or other upside for Sunesis. Following the purchase of the revenue participation right by RPI Finance Trust (“RPI”), an entity related to Royalty Pharma, we are required to pay RPI a specified percentage of any net sales of vosaroxin. If we fail to make timely payments due to RPI under the Royalty Agreement, RPI may require us to repurchase the revenue participation right. As collateral for these payments, we granted RPI a security interest in certain of our assets, including our intellectual property related to vosaroxin. Upon marketing approval of vosaroxin, Western Alliance, the Collateral Agent (the “Collateral Agent”) of our loan and security agreement (the “Loan Agreement”), with Bridge Bank, a division of Western Alliance Bank (“Western Bank”) and Solar Capital Ltd (“Solar Capital”, and collectively with Western Bank, the “Lenders”), for the benefit of the Lenders under our Loan Agreement, will also have a perfected security interest in our intellectual property rights relating to vosaroxin. We will not realize any gain from a vosaroxin licensing agreement until all of our obligations are met.
Any future workforce and expense reductions may have an adverse impact on our internal programs, our ability to hire and retain key personnel and may be distracting to management.
We have, in the past, implemented workforce reductions. Depending on our need for additional funding and expense control, we may be required to implement further workforce and expense reductions in the future. Further workforce and expense reductions could result in reduced progress on our internal programs. In addition, employees, whether or not directly affected by a reduction, may seek future employment with our business partners or competitors. Although our employees are required to sign a confidentiality agreement at the time of hire, the confidentiality of certain proprietary information and knowledge may not be maintained in the course of any such future employment. Further, we believe that our future success will depend in large part upon our ability to attract and retain highly skilled personnel. We may have difficulty retaining and attracting such personnel as a result of a perceived risk of future workforce and expense reductions. In addition, the implementation of expense reduction programs may result in the diversion of efforts of our executive management team and other key employees, which could adversely affect our business.
We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our employees’ former employers.
Many of our employees were previously employed at biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that we or our employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel.
A loss of key personnel or the work product of current or former personnel could hamper or prevent our ability to commercialize vecabrutinib, SNS-510, and other product candidates, which could severely harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.
22
We may lose key employees or have difficulty hiring employees to fill key roles
.
A loss of key personnel or difficulty in hiring employees to fill key roles could slow or prevent our ability to develop and commercialize our products. For example, we currently have an ongoing search for a Chief Executive Officer. If we have difficulty hiring a Chief Executive Officer it may adversely impact our future prospects.
We depend on various consultants and advisors for the success and continuation of our development efforts.
We work extensively with various consultants and advisors, who provide advice and/or services in various business and development functions, including clinical development, operations and strategy, regulatory matters, biostatistics, legal and finance. The potential success of our drug development programs depends, in part, on continued collaborations with certain of these consultants and advisors. Our consultants and advisors are not our employees and may have commitments and obligations to other entities that may limit their availability to us. We do not know if we will be able to maintain such relationships or that such consultants and advisors will not enter into other arrangements with competitors, any of which could have a detrimental impact on our development objectives and our business.
If conflicts of interest, or a failure or dispute of reporting or diligence efforts arise between our current or future licensees or collaboration partners, if any, and us, any of them may act in their self-interest, which may be adverse to our interests.
If a conflict of interest arises between us and one or more of our current or potential future licensees or collaboration partners, if any, they may act in their own self-interest or otherwise in a way that is not in the interest of our company or our stockholders. Biogen, Takeda, or potential future licensees or collaboration partners, if any, are conducting or may conduct product development efforts within the disease area that is the subject of a license or collaboration with our company. In current or potential future licenses or collaborations, if any, we have agreed or may agree not to conduct, independently or with any third party, any research that is competitive with the research conducted under our licenses or collaborations. Our licensees or collaboration partners, however, may develop, either alone or with others, products in related fields that are competitive with the product candidates that are the subject of these licenses or collaborations. Competing products, either developed by our licensees or collaboration partners or to which our licensees or collaboration partners have rights, may result in their withdrawal of support for a product candidate covered by the license or collaboration agreement.
If one or more of our current or potential future licensees or collaboration partners, if any, were to breach or terminate their license or collaboration agreements with us or otherwise fail to perform their obligations thereunder in a timely manner, the preclinical or clinical development or commercialization of the affected product candidates could be delayed or terminated. We do not know whether our licensees or collaboration partners will pursue alternative technologies or develop alternative product candidates, either on their own or in collaboration with others, including our competitors, as a means for developing treatments for the diseases targeted by licenses or collaboration agreements with our company.
We and our current collaboration partners have certain reporting and diligence obligations to each other, and failure to report, or disagreement over the impact of information reported, or a lack of diligent efforts, or dispute of the impact of the efforts, may be adverse to our interests, the development of the product candidates and could lead to an ultimate withdrawal or dispute of the rights to a product candidate covered by the license or collaboration agreement.
Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses.
Changing laws, regulations and standards relating to corporate governance and public disclosure may create uncertainty regarding compliance matters. New or changed laws, regulations and standards are subject to varying interpretations in many cases. As a result, their application in practice may evolve over time. We are committed to maintaining high standards of corporate governance and public disclosure. Complying with evolving interpretations of new or changed legal requirements may cause us to incur higher costs as we revise current practices, policies and procedures, and may divert management time and attention from potential revenue-generating activities to compliance matters. If our efforts to comply with new or changed laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, our reputation may also be harmed. Further, our board members, chief executive officer and chief financial officer could face an increased risk of personal liability in connection with the performance of their duties. As a result, we may have difficulty attracting and retaining qualified board members and executive officers, which could harm our business. Our Directors and Officers insurance provides certain coverage to our board members and executive officers, but the cost of coverage may be prohibitively expensive or not provide enough coverage.
23
Raising funds through lending arrangements or revenue participation agreem
ents may restrict our operations or produce other adverse results.
Our Loan Agreement and the two amendments entered into in 2017 (the “Amendments”) contain a variety of affirmative covenants, including, without limitation, certain information delivery requirements, obligations to maintain certain insurance and certain notice requirements, and negative covenants, including, without limitation, restrictions on incurring certain additional indebtedness, making certain asset dispositions, entering into certain mergers, acquisitions or other business combination transactions or incurring any non-permitted lien or other encumbrance on our assets. Upon the occurrence of an event of default under the Loan Agreement and the Amendments (subject to cure periods for certain events of default), all amounts owed by us thereunder would begin to bear interest at a rate that is 5.0% higher than the rate that would otherwise be applicable and may be declared immediately due and payable by the Collateral Agent. In the event of default by us, the Lenders would be entitled to exercise their remedies thereunder, including the right to accelerate the debt, upon which we may be required to repay all amounts then outstanding under the Loan Agreement and the Amendments, which could harm our financial condition.
The Amendments modified the loan repayment terms to allow us to extend the interest-only period to January 1, 2019, upon receipt of receipt of at least Twenty-Five Million dollars ($25,000,000) in unrestricted cash proceeds on or prior to September 15, 2018. We qualified for the extension and the interest-only period was extended to January 1, 2019. We began making principal payments in the beginning of 2019. We will require additional financing to repay our debt and may be unable to repay the principal amounts under the Loan Agreement as they come due, which could harm our financial condition.
The Collateral Agent, for the benefit of the Lenders, has a perfected security interest in substantially all of our property, rights and assets, except for intellectual property, to secure the payment of all amounts owed to the Lenders under the Loan Agreement
.
We are exposed to risks related to foreign currency exchange rates.
Some of our costs and expenses are denominated in foreign currencies. When the U.S. dollar weakens against the Euro or British pound, the U.S. dollar value of the foreign currency denominated expense increases, and when the U.S. dollar strengthens against the Euro or British pound, the U.S. dollar value of the foreign currency denominated expense decreases. Consequently, changes in exchange rates, and in particular a weakening of the U.S. dollar, may adversely affect our results of operations. We have and may continue to purchase certain European currencies or highly-rated investments denominated in such currencies to manage the risk of future movements in foreign exchange rates that would affect such payables, in accordance with our investment policy. However, there is no guarantee that the related gains and losses will substantially offset each other, and we may be subject to significant exchange gains or losses as currencies fluctuate from quarter to quarter.
Our facilities are located near known earthquake fault zones, and the occurrence of an earthquake or other catastrophic disaster, or interruption by man-made problems such as network security breaches, viruses or terrorism, could cause damage to our facilities and equipment, which could require us to cease or curtail operations.
Our facilities are located in the San Francisco Bay Area near known earthquake fault zones and are vulnerable to significant damage from earthquakes. We are also vulnerable to damage from other types of disasters, including fires, floods, power loss, communications failures and similar events. Despite the implementation of network security measures, our networks also may be vulnerable to computer viruses, break-ins and similar disruptions. We rely on information technology systems to operate our business and to communicate among our workforce and with third parties. If any disruption were to occur, whether caused by a natural disaster or by manmade problems, our ability to operate our business at our facilities may be seriously or completely impaired and our data could be lost or destroyed.
Our systems are potentially vulnerable to data security breaches, whether by employees or others, that may expose sensitive data to unauthorized persons. If we are unable to prevent such data security breaches or implement satisfactory remedial measures, our operations could be disrupted, and we may suffer loss of reputation, financial loss and other regulatory penalties because of lost or misappropriated information. In addition, these breaches and other inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type described above. Moreover, the prevalent use of mobile devices that access confidential information increases the risk of data security breaches, which could lead to the loss of confidential information, trade secrets or other intellectual property. While we have implemented security measures to protect our data security and information technology systems, such measures may not prevent such events. Such disruptions and breaches of security could have a material adverse effect on our business, financial condition and results of operations.
24
Risks Related to Our Industry
The regulatory approval process is expensive, time consuming and uncertain and may prevent us from obtaining approval for the commercialization of our product candidates.
The research, testing, manufacturing, selling and marketing of product candidates are subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries, and regulations differ from country to country. Neither we nor our present or potential future collaboration or licensing partners, if any, are permitted to market our product candidates in the United States or Europe until we receive approval of an MAA or NDA for these respective territories, or in any other country without the equivalent marketing approval from such country. We have not received marketing approval for vecabrutinib in any jurisdiction. In addition, failure to comply with FDA, EMA, and other applicable U.S. and foreign regulatory requirements may subject us to administrative or judicially imposed sanctions, including warning letters, civil and criminal penalties, injunctions, product seizure or detention, product recalls, total or partial suspension of production, and refusal to approve pending MAAs, NDAs, supplements to approved MAAs, NDAs or their equivalents in other territories.
Regulatory approval of an MAA or NDA or their equivalent in other territories is not guaranteed, and the approval process is expensive, uncertain and may take several years. Furthermore, the development process for oncology products may take longer than in other therapeutic areas. Regulatory authorities have substantial discretion in the drug approval process. Despite the time and expense exerted, failure can occur at any stage, and we could encounter problems that cause us to abandon clinical trials or to repeat or perform additional preclinical studies and clinical trials. The number of preclinical studies and clinical trials that will be required for marketing approval varies depending on the drug candidate, the disease or condition that the drug candidate is designed to address, and the regulations applicable to any particular drug candidate.
The FDA, EMA or other foreign regulatory authority can delay, limit or deny approval of a drug candidate for many reasons, including:
|
•
|
the drug candidate may not be deemed safe or effective;
|
|
•
|
regulatory officials may not find the data from preclinical studies and clinical trials sufficient;
|
|
•
|
the FDA, EMA or other foreign regulatory authority might not approve our or our third-party manufacturers’ processes or facilities; or
|
|
•
|
the FDA, EMA or other foreign regulatory authority may change its approval policies or adopt new regulations.
|
We may be subject to costly claims related to our clinical trials and may not be able to obtain adequate insurance.
Because we conduct clinical trials in humans, we face the risk that the use of vecabrutinib, SNS-510, or other product candidates, if any, will result in adverse side effects. We cannot predict the possible harms or side effects that may result from our clinical trials. Although we have clinical trial liability insurance, our insurance may be insufficient to cover any such events. We do not know whether we will be able to continue to obtain clinical trial coverage on acceptable terms, or at all. We may not have sufficient resources to pay for any liabilities resulting from a claim excluded from, or beyond the limit of, our insurance coverage. There is also a risk that third parties that we have agreed to indemnify could incur liability. Any litigation arising from our clinical trials, even if we were ultimately successful, would consume substantial amounts of our financial and managerial resources and may create adverse publicity.
Even if we receive regulatory approval to sell vecabrutinib, SNS-510, or other product candidates, the market may not be receptive.
Even if one of our product candidates obtains regulatory approval, it may not gain market acceptance among physicians, patients, healthcare payors and/or the medical community. We believe that the degree of market acceptance will depend on a number of factors, including:
|
•
|
the timing of market introduction of competitive products;
|
|
•
|
the efficacy of our product;

If vecabrutinib, SNS-510, or other product candidates fail to achieve market acceptance, due to unacceptable side effects or any other reasons, we may not be able to generate significant revenue or to achieve or sustain profitability.
Even if we receive regulatory approval for vecabrutinib, SNS-510, or any other future product candidate, we will be subject to ongoing FDA, EMA and other regulatory obligations and continued regulatory review, which may result in significant additional expense and limit our ability to commercialize vecabrutinib, SNS-510, or any other future product candidate.
Any regulatory approvals that we or our potential future collaboration partners receive for vecabrutinib, SNS-510, or our future product candidates, if any, may also be subject to limitations on the indicated uses for which the product may be marketed or contain requirements for potentially costly post-marketing trials. In addition, even if approved, the manufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion and recordkeeping for any product will be subject to extensive and ongoing regulatory requirements. The subsequent discovery of previously unknown problems with a 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.
The FDA and other agencies, including the Department of Justice (“DOJ”), closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are marketed and distributed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA and DOJ impose stringent restrictions on manufacturers’ communications regarding off-label use and if we do not market our products for their approved indications, we may be subject to enforcement action for off-label marketing. Violations of the Federal Food, Drug, and Cosmetic Act and other statutes, including the False Claims Act, relating to the promotion and advertising of prescription drugs may lead to investigations and enforcement actions alleging violations of federal and state health care fraud and abuse laws and state consumer protection laws.
Regulatory policies may change and additional government regulations may be enacted that could prevent or delay regulatory approval of our product candidates. 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, Europe or other territories. If we are not able to maintain regulatory compliance, we might not be permitted to market our future products and we may not achieve or sustain profitability. Other penalties for failing to comply with regulatory requirements include restrictions on such products, manufacturers or manufacturing processes; restrictions on the labeling or marketing of a product; restrictions on distribution or use of a product; requirements to conduct post-marketing studies or clinical trials; warning letters or untitled letters; withdrawal of the products from the market; refusal to approve pending applications or supplements to approved applications that we submit; recall of products; damage to relationships with any potential collaborators; unfavorable press coverage and damage to our reputation; fines, restitution or disgorgement of profits or revenues; suspension or withdrawal of marketing approvals; refusal to permit the import or export of our products; product seizure; injunctions or the imposition of civil or criminal penalties; and litigation involving patients using our products. Additionally, failure to comply with the European Union’s requirements regarding the protection of personal information also can lead to significant penalties and sanctions.
The coverage and reimbursement status of newly approved drugs is uncertain and may be impacted by current and future legislation, and failure to obtain adequate coverage and reimbursement could limit our ability to market our product candidates and decrease our ability to generate revenue.
There is significant uncertainty related to the third party coverage and reimbursement of newly approved drugs both nationally and internationally. The commercial success of our future products, if any, in both domestic and international markets depends on whether third-party coverage and reimbursement is available for the ordering of our future products by the medical profession for use by their patients. Medicare, Medicaid, health maintenance organizations and other third-party payors are increasingly attempting to manage healthcare costs by limiting both coverage and the level of reimbursement of new drugs and, as a result, they may not cover or provide adequate payment for our future products. These payors may not view our future products as cost-effective, and reimbursement may not be available to consumers or may not be sufficient to allow our future products to be marketed on a competitive basis.
Likewise, in the United States and some foreign jurisdictions, there have been a number of legislative or regulatory efforts to control or reduce healthcare costs or reform government healthcare programs that could result in lower prices or rejection of our future products. Such efforts have resulted in several recent United States congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products.

For example, at the federal level, the Trump administration released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to
increase manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out of pocket costs of drug products paid by consumers. On January
31, 2019, the U.S. Department of Health and Human Services, Office of Inspector General, proposed modifications to the federal Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products to consumers which, among other
things, if finalized, will affect discounts paid by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit managers working with these organizations. While some of these and other proposed measures may require auth
orization through additional legislation to become effective, Congress and the Trump administration have each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs.
Changes in coverage and reimbursemen
t policies or healthcare cost containment initiatives that may limit or restrict reimbursement for our future products may reduce any future product revenue.
Additionally, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, was enacted, which made a number of substantial changes in the way healthcare is financed by both governmental and private insurers. In the years since its enactment, there have been, and continue to be, significant developments in, and continued legislative activity around, attempts to repeal or repeal and replace the ACA. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA such as removing penalties, starting January 1, 2019, for not complying with the ACA’s individual mandate to carry health insurance and delaying the implementation of certain ACA-mandated fees. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the TCJA. While the Texas U.S. District Court Judge, as well as the Trump administration and CMS, have stated that the ruling will have no immediate effect pending appeal of the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA and our business and operations.
The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products.
Our relationships with healthcare providers, clinical investigators, and third party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which, in the event of a violation, could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.
Healthcare providers, clinical investigators, and third party payors will play a primary role in the recommendation and prescription of any drug candidates for which we obtain marketing approval. Our current and future arrangements with healthcare providers, clinical investigators and third party payors may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute any products for which we obtain marketing approval. Restrictions under applicable state, federal and foreign healthcare laws and regulations include the following:
|
•
|
The federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce or in return for either the referral of an individual, or the purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item, good, facility or service reimbursable under Medicare, Medicaid or other federal healthcare programs;
|
|
•
|
Federal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, prohibit any person or entity from, among other things, knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to be made, a false statement to have a false claim paid;
|
|
•
|
HIPAA prohibits, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and 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;
|
|
•
|
HIPAA, as amended by the HITECH and its implementing regulations, among other things, imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information. HITECH, among other things, makes HIPAA’s security standards directly applicable to business associates, independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity; created four new tiers of civil monetary penalties; amended HIPAA to make civil and criminal penalties directly applicable to business associates; and gave state attorneys general new authority to file civil actions to enforce the federal HIPAA laws;

27
|
•
|
the federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices, biologicals and m
edical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain except
ions) to annually report to CMS
information related to certain payments or other transfers of value provided to physician
s and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate family mem
bers; and
|
|
•
|
analogous local, state and foreign laws and regulations, such as state anti-kickback and false claims laws, transparency statutes, and privacy and security laws. Such laws may be broader than the federal law, including that they may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by third party payors, including private insurers. There also are an increasing number of state laws that require manufacturers to file reports with states regarding drug pricing and marketing information, tracking and reporting of gifts, compensation, other remuneration and items of value provided to health care professionals and health care entities, or marketing expenditures; require pharmaceutical companies to, among other things, establish and implement commercial compliance programs or codes of conducts; and/or require a pharmaceutical company’s sales representatives to be registered or licensed by the state or local governmental entity. State and foreign laws also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the health regulatory laws described above or any other laws that apply to us, we may be subject to a wide range of sanctions and penalties, including potentially significant criminal, and civil and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, integrity obligations, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. We are unable to predict whether we would be subject to actions under these laws or the impact of such actions. However, the cost of defending any such claims, as well as any sanctions imposed, could adversely affect our financial performance and disrupt our business operations.
Foreign governments often impose strict price controls, which may adversely affect our future profitability.
If we or a potential future collaboration partner obtain approval in one or more foreign jurisdictions, we or the potential future collaboration partner will be subject to rules and regulations in those jurisdictions. In some foreign countries, particularly in the European Union, prescription drug pricing is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a drug candidate. To obtain reimbursement or pricing approval in some countries, we or a potential future collaboration partner may be required to conduct a clinical trial that compares the cost-effectiveness of our products to other available therapies. If reimbursement is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability.
We may incur significant costs complying with environmental laws and regulations, and failure to comply with these laws and regulations could expose us to significant liabilities.
We, through third-party contractors, use hazardous chemicals and radioactive and biological materials in our business and are subject to a variety of federal, state, regional and local laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these materials. Although we believe our safety procedures for handling and disposing of these materials and waste products comply with these laws and regulations, we cannot eliminate the risk of accidental injury or contamination from the use, storage, handling or disposal of hazardous materials. In the event of contamination or injury, we could be held liable for any resulting damages, and any liability could significantly exceed our insurance coverage, which is limited for pollution cleanup and contamination.
The comprehensive tax reform bill could adversely affect our business and financial condition.
On
December 22, 2017, the President signed into law tax legislation, or the Tax Act, which significantly reforms the Internal Revenue Code of 1986, as amended. The Tax Act, among other things, contains significant changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%; limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small businesses); limitation of the deduction of net operating losses generated in tax years beginning after December 31, 2017 to 80% of taxable income, indefinite carryforward of net operating losses generated in tax years after 2018 and elimination of net operating loss carrybacks; changes in the treatment of offshore earnings regardless of whether they are repatriated; current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations, mandatory capitalization of research and development expenses beginning in 2022; immediate deductions for certain new investments
28
instead of deductio
ns for depreciation expense over time; further deduction limits on executive compensation;
and modifying,
repeal
ing and creating
many other
business deductions and credits,
including the reduction in the
orphan drug credit from 50% to 25% of qualifying expenditures.
We continue to examine the impact the Tax Act may have on our business. Notwithstanding the reduction in the corporate income tax rate, the overall impact of the Tax Act is uncertain and our business and financial condition could be adversely affected. The impact of the Tax Act on holders of our common stock is also uncertain and could be adverse.
Our ability to use net operating loss carryforwards to offset future taxable income, and our ability to use tax credit carryforwards, may be subject to certain limitations.
Our ability to use our federal and state net operating losses, or NOLs, to offset potential future taxable income and related income taxes that would otherwise be due is dependent upon our generation of future taxable income, and we cannot predict with certainty when, or whether, we will generate sufficient taxable income to use all of our NOLs.
As of December 31, 2018, we reported U.S. federal and state NOLs of approximately $448.2 million and $288.3 million, respectively. Our federal NOLs generated prior to 2018 will continue to be governed by the NOL tax rules as they existed prior to the adoption of the Tax Act, which means that generally they will expire 20 years after they were generated if not used prior thereto. Many states have similar laws, and our state NOLs will begin to expire in 2028. Accordingly, these federal and state NOLs could expire unused and be unavailable to offset future income tax liabilities. Under the Tax Act, federal NOLs incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such federal NOL’s is limited to 80% of current year taxable income. It is uncertain if and to what extent various states will conform to the Tax Act.
In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, our ability to utilize these NOLs and other tax attributes, such as federal tax credits, in any taxable year may be limited if we have experienced an “ownership change.” Generally, a Section 382 ownership change occurs if one or more stockholders or groups of stockholders who owns at least 5% of a corporation’s stock increases its ownership by more than 50 percentage points over its lowest ownership percentage within a three-year testing period. Similar rules may apply under state tax laws. Any such material limitation or expiration of our NOLs may harm our future operating results by effectively increasing our future tax obligations.
Risks Related to Our Common Stock
The price of our common stock may continue to be volatile, and the value of an investment in our common stock may decline.
In 2018, our common stock traded as low as $0.20 and as high as $7.69. Factors that could cause continued volatility in the market price of our common stock include, but are not limited to:
|
•
|
all the other risks mentioned herein, including but not limited to our ability to raise additional capital to fund our operations and complete our clinical development plans, compliance with government regulations, the safety and efficacy of our products, and our ability to protect our intellectual property;
|
|
•
|
announcements relating to restructuring and other operational changes;
|
|
•
|
market conditions in the pharmaceutical, biopharmaceutical and biotechnology sectors;
|
|
•
|
issuance of new or changed securities analysts’ reports or recommendations;
|
|
•
|
announcements relating to our arrangements with Biogen, Takeda or RPI;
|
|
•
|
actual and anticipated fluctuations in our quarterly operating results;
|
|
•
|
deviations in our operating results from the estimates of analysts;
|
|
•
|
litigation or public concern about the safety of future products, if any;
|
|
•
|
failure to develop or sustain an active and liquid trading market for our common stock;
|
|
•
|
short-selling or manipulation of our common stock by investors;
|
|
•
|
sales of our common stock by our officers, directors or significant stockholders; and
|
|
•
|
additions or departures of key personnel.

Our failure to meet the continued listing requirements of The Nasdaq Capital Market could result in a delisting of our common stock.
Our common stock is listed on The Nasdaq Capital Market, which imposes, among other requirements a minimum bid requirement. Our common stock traded for less than $1.00 for 30 consecutive trading days, and we received notice of this from the Listing Qualifications Staff of The Nasdaq Stock Market LLC on January 11, 2019. Under Nasdaq Listing Rule 5810(c)(3)(A), we have been granted a 180 calendar day grace period, or until July 10, 2019, to regain compliance with the minimum bid price requirement. The minimum bid price requirement will be met if our common stock has a minimum closing bid price of at least $1.00 per share for a minimum of 10 consecutive business days during the 180 calendar day grace period. There can be no assurance that we will be able to regain compliance or that Nasdaq will grant us a further extension of time to regain compliance, if necessary.
The delisting of our common stock from Nasdaq may make it more difficult for us to raise capital on favorable terms in the future, or at all. Such a delisting would likely have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. Further, if our common stock were to be delisted from The Nasdaq Capital Market, our common stock would cease to be recognized as a covered security and we would be subject to additional regulation in each state in which we offer our securities. Moreover, there is no assurance that any actions that we take to restore our compliance with the Nasdaq minimum bid requirement would stabilize the market price or improve the liquidity of our common stock, prevent our common stock from falling below the Nasdaq minimum bid price required for continued listing again, or prevent future non-compliance with Nasdaq’s listing requirements.
Provisions of our charter documents or Delaware law could delay or prevent an acquisition of our company, even if the acquisition would be beneficial to our stockholders, and could make it more difficult to change management.
Provisions of our amended and restated certificate of incorporation and amended and restated bylaws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders might otherwise consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. In addition, these provisions may frustrate or prevent any attempt by our stockholders to replace or remove our current management by making it more difficult to replace or remove our board of directors. These provisions include:
|
•
|
a classified board of directors so that not all directors are elected at one time;
|
|
•
|
a prohibition on stockholder action through written consent;
|
|
•
|
limitations on our stockholders’ ability to call special meetings of stockholders;
|
|
•
|
an advance notice requirement for stockholder proposals and nominations; and
|
|
•
|
the authority of our board of directors to issue preferred stock with such terms as our board of directors may determine.
|
In addition, Delaware law prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person who, together with its affiliates, owns or within the last three years has owned 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. Accordingly, Delaware law may discourage, delay or prevent a change in control of our company.
Provisions in our charter documents and provisions of Delaware law could limit the price that investors are willing to pay in the future for shares of our common stock.
We have never paid dividends on our capital stock and we do not anticipate paying any cash dividends in the foreseeable future.
We have never declared or paid cash dividends on our capital stock. We do not anticipate paying any cash dividends on our capital stock in the foreseeable future. In addition, under the terms of our Loan Agreement with the Lenders, we are precluded from paying cash dividends without the prior written consent of the Lenders. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. As a result, capital appreciation, if any, of our common stock will be our stockholders’ sole source of gain for the foreseeable future.
We are at risk of securities class action litigation.
In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology companies have experienced greater than average stock price volatility in recent years. These broad market fluctuations may adversely affect the trading price or liquidity of our common stock. In the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the issuer. If any of our stockholders were to bring such a lawsuit against us, we could incur substantial costs defending the lawsuit and the attention of our management would be diverted from the operation of our business.
30
Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, 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 will be needed in the future to continue our planned operations. To raise capital, we may sell substantial amounts of common stock or securities convertible into or exchangeable for common stock in one or more transactions at prices and in a manner we determine from time to time, including pursuant to our Controlled Equity Offering
SM
sales agreement (“the Sales Agreement”), with Cantor Fitzgerald & Co. (“Cantor”), or any similar arrangements into which we may enter. These future issuances of common stock or common stock-related securities, together with the exercise of outstanding options and any additional shares issued in connection with acquisitions or in-licenses, if any, may result in material dilution to our investors. Such sales may also result in material dilution to our existing stockholders, and new investors could gain rights, preferences and privileges senior to those of holders of our common stock.
Pursuant to our equity incentive plans, our compensation committee is authorized to grant equity-based incentive awards to our employees, non-employee directors and consultants. Future grants of RSUs, options and other equity awards and issuances of common stock under our equity incentive plans will result in dilution and may have an adverse effect on the market price of our common stock.
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 and our business. In the event securities or industry analysts who cover us downgrade our stock or publish unfavorable research about us or our business, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.
