Cocrystal Pharma, Inc. 10-K

Item 1. Business. Overview Cocrystal Pharma, Inc. (the “Company” or “Cocrystal”) is a biotechnology company seeking to discover and develop novel antiviral therapeutics as treatments for serious and/or chronic viral diseases. We employ unique structure-based technologies and Nobel Prize winning expertise to create first- and best-in-class antiviral drugs. These technologies are designed to efficiently deliver small molecule therapeutics that are safe, effective, and convenient to administer. We have identified promising discovery, preclinical and clinical stage antiviral compounds for unmet medical needs caused by influenza virus, coronavirus, hepatitis C virus (“HCV”), and norovirus infections. The Company operates in one segment. Management uses cash flows as the primary measure to manage its business and does not segment its business for internal reporting or decision-making. Cocrystal Technology We are developing antiviral therapeutics that inhibit the essential viral replication function of RNA viruses causing acute and chronic viral diseases. Our goals include treating influenza virus, coronavirus, and norovirus infections by discovering and developing drug candidates targeting the viral replication process. Additionally, one of our goals is to decrease the duration of HCV therapy by advancing our drug candidate targeting the HCV RNA-dependent RNA polymerase enzyme through partnerships and/or licensing activities. In the case of coronavirus, we target a major protease enzyme that produces the active form of the viral replication enzyme. To discover and design these inhibitors, we use a proprietary platform comprising computation, medicinal chemistry, X-ray crystallography, and our extensive know-how. We determine the structures of cocrystals containing the inhibitors bound to the enzyme or protein to guide our structure-based drug design. We also use advanced computational methods to screen and design product candidates using proprietary cocrystal structural information. In designing the candidates, we seek to anticipate and avert potential viral mutations leading to resistance. By designing and selecting drug candidates that interrupt the viral replication process and also have specific binding characteristics, we seek to develop drugs that are not only effective against both the virus and possible mutants of the virus, but which also have reduced off-target interactions that cause undesirable clinical side effects. The successful application of our approach requires an extensive knowledge of viruses and drug targets. In addition, knowledge and experience in the fields of structural biology, and enzymology are required. We developed our proprietary structure-based drug design under the guidance of Dr. Roger Kornberg, our Chief Scientist, Chairman of our Scientific Advisory Board and recipient of the Nobel Prize in Chemistry in 2006. Our drug discovery process focuses on the highly conserved regions of the viral enzymes and inhibitor-enzyme interactions at the atomic level. Additionally, we have developed proprietary chemical libraries consisting of non-nucleoside inhibitors, metal-binding inhibitors, and drug-like fragments. Our drug discovery process is different from traditional, empirical, medicinal chemistry approaches that often require iterative high-throughput compound screening and lengthy hit-to-lead processes. We will continue developing preclinical and clinical drug candidates using our proprietary drug discovery technology. 3 The Company’s proprietary technology integrates several powerful and specialized techniques: (1) Selection of viral drug targets amenable to broad-spectrum antiviral drug development and essential for viral genome replication; (2) Atomic resolution 3-D structure determination of drug binding pockets; (3) In-depth computational analysis of conservation of drug-binding pockets and critical molecular interactions between antiviral inhibitors and amino acid residues of the target molecule’s drug-binding pocket; (4) Cocrystal structure determinations to inform hit identification, hit-to-lead, and lead optimization processes; (5) Molecular modeling and computer-guided lead discovery to support rational chemical modifications based on structure-activity relationships, or SAR, of candidate inhibitor compounds; (6) Knowledge of enzymatic mechanisms to guide the design of drugs with exceptional affinity, specificity, and broad-spectrum activity; and (7) Platforms for rapid identification of antiviral enzyme inhibitors showing broad-spectrum antiviral activity. We have applied these techniques to develop antiviral inhibitors of four important viruses: influenza virus, coronavirus, HCV and norovirus. Market-Driven Product Profiles In all of our programs our goal is to develop best-in-class broad-spectrum antiviral drugs with high-barrier-to-drug resistance. An ideal product for an antiviral therapy would have at least the following characteristics: (1) High barrier to viral resistance; (2) Effective against all viral subtypes that cause disease; (3) Fast onset of action and/or shortened therapeutic time; (4) Good safety and tolerability profile; and (5) Multiple routes of administration including oral, inhalation, and/or injection. Even at the discovery stage of drug development, we select compounds with these factors in mind. Furthermore, we believe our technology is capable of delivering therapies that satisfy all of these key factors, as detailed below. High barrier to drug resistance : Drug resistance is a major obstacle to developing effective antiviral therapies. Viruses can reproduce rapidly and in enormous quantities in infected human cells. During viral replication, random changes in the viral genome, called mutations, develop. If such a mutation occurs in a region of the viral genome that is targeted by a given antiviral therapy, that therapy may no longer be effective against the mutated virus. These mutated or “resistant” viruses can freely infect and multiply even in individuals who have received drug treatment. In some cases, resistant virus strains may even predominate. For example, in the 2009 swine influenza pandemic, the predominant strain was resistant to the best available therapies. In the current COVID-19 pandemic mutated viruses have been identified and sequenced demonstrating that the potential for resistance to current drugs and reduced effectiveness of vaccines is already present. 4 The Company’s focus on viral replication proteins can overcome the obstacle of viral resistance. We identify and target critical components of viral replication proteins that are essential for function, and therefore, sensitive to change. A mutation in these critical components is likely to inactivate the replication protein and, in turn, render the virus incapable of replicating. Because such mutations cannot propagate, the virus cannot effectively develop resistance to the enzyme inhibitors we employ. We test the effectiveness of our compounds against potential viral mutations and select compounds with the highest barrier to resistance. Broadly effective against major strains responsible for a viral disease : For any given viral disease, there are different strains of viruses that cause the disease. For example, there are three types of influenza viruses, A, B, and C. Influenza A and B viruses are significant human respiratory pathogens that cause seasonal flu. Influenza A viruses can also cause an influenza pandemic. Influenza C is a subtype of the influenza virus that tends to cause only mild illness and is not responsible for seasonal or pandemic infections. Our goal is to design and develop drug candidates that will be effective on the broadest possible range of viruses causing the disease. Many antiviral drugs available today are effective only against certain strains of a given virus and less effective or not effective at all against other strains. To address this problem, we are developing drug candidates that specifically target viral proteins involved in viral replication. Despite the various strains of virus that may exist, these enzymes required for viral replication are essentially similar (highly conserved) among all strains of a given virus. By targeting these highly conserved regions of the replication enzymes, our antiviral compounds are designed and tested to be effective against major virus strains. Replication enzymes are generally conserved not only among subtypes of a given virus but also among many different viruses, creating an opportunity for the development of broad-spectrum antiviral drugs. Fast onset of action: Antiviral drugs are needed with faster onset of viral load reduction resulting in shorter treatment time. Safety and tolerability : All drugs have side effects, also referred to as adverse effects. These usually result from a drug’s ability to bind to human molecules (usually proteins). When this interaction is intentional (i.e., part of the drug’s mechanism of action), the adverse effects are classified as on-target effects. When this interaction is unintentional (i.e., resulting from the drug’s interaction with an unintended human molecule), the effects are called off-target effects. Our inhibitors target viral replication enzymes, which are generally unique to viruses. Because the targets are viral, not human, minimal adverse effects may be the result. During the discovery phase, we evaluate candidate compounds for potential cross-reactivity with human replication enzymes and attempt to eliminate those compounds that are cross-reactive with human homologous proteins. Ease of administration: We select compounds for development that can be administered orally, preferably once daily in pill-form, or by inhalation or injection. Research and Development Update During the year ended December 31, 2020 the Company focused its research and development efforts primarily in three areas: Influenza infections We have several preclinical candidates under development for the treatment of influenza infection. CC-42344, a novel PB2 inhibitor, has been selected as a preclinical lead. This candidate binds to a highly conserved PB2 site of influenza polymerase complex (PB1: PB2: PA) and exhibits a novel mechanism of action. CC-42344 showed excellent antiviral activity against influenza A strains, including avian pandemic strains and Tamiflu resistant strains, and has favorable pharmacokinetic and drug resistance profiles. We are currently conducting additional preclinical IND enabling studies and plan to initiate a Phase 1 study in the third quarter of 2021. In addition, novel inhibitors effective against both influenza strains A and B have been identified and are in the preclinical stage. Several of these have potencies approaching single digit nanomolar. On January 2, 2019, the Company entered into an Exclusive License and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck Sharp & Dohme Corp. (“Merck”) to discover and develop certain proprietary influenza A/B antiviral agents. See “Item 1 – Business – Collaborations – Merck Collaboration” for more information. 5 In January 2021, we announced that we completed all research obligations under the Merck exclusive worldwide license and collaboration agreement, and that Merck is now solely responsible for further development of the influenza A/B antiviral compounds that were discovered using Cocrystal’s unique structure-based technologies and Nobel Prize-winning expertise. Merck is continuing development of the compounds under the terms of our Collaboration Agreement. Coronavirus infections In December 2020 we announced the selection of CDI-45205 as the lead compound for further development against coronaviruses including SARS-CoV-2, that causes COVID-19. CDI-45205 was one of the broad-spectrum protease inhibitors that were obtained from Kansas State University Research Foundation (“KSURF”) under an exclusive license agreement announced in April 2020. That agreement provides Cocrystal with an exclusive, royalty-bearing license to develop and commercialize therapeutic, diagnostic and prophylactic products against coronaviruses, caliciviruses and picornaviruses based on antivirals discovered by KSURF. See “Collaborations – Kansas State University Research Foundation.” The Company believes these protease inhibitors have the ability to convert the inactive SARS-CoV-2 polymerase replication enzymes into an active form. We are working toward pre-IND status with CDI-45205. We are also developing COVID-19 replication inhibitors using our drug discovery platform and expect to develop such additional COVID-19 inhibitors with novel mechanism of action in 2021. 6 Norovirus Infections We continue to identify and develop non-nucleoside polymerase and protease inhibitors using the Company’s proprietary structure-based drug design technology platform. In addition, we now have exclusive rights to norovirus protease inhibitors for use in humans obtained in the license from Kansas State University Research Foundation (see under Collaborations below). We expect to complete proof-of-concept animal study in the first half of 2021. Therapeutic Targets Influenza: A worldwide public health problem, including the potential for pandemic disease . Influenza is a severe respiratory illness, caused primarily by influenza A or B virus. The Centers for Disease Control and Prevention (the “CDC”) estimates that influenza was linked to approximately 79,000 deaths and 960,000 hospitalizations in the United States during the 2017-2018 flu season. According to the report published by BCC Research in May 2018, the global influenza market was valued at approximately $5.6 billion in 2017 and is expected to reach nearly $6.5 billion by 2022, increasing at a compound annual growth rate (CAGR) of 3.0% from 2017 through 2022. Currently, approved antiviral treatments for influenza are effective, but burdened with significant viral resistance. Strains of influenza virus that are resistant to the approved treatments osteltamivir phosphate (Tamiflu(R)) and zanamavir (Relenza(R)) have appeared, and in some cases predominate. For example, the predominant strain of the 2009 swine influenza pandemic was resistant to Tamiflu. These drugs target viral neuraminidase enzymes, which are not highly conserved between viral strains. In fact, different influenza virus strains such as H1N1 and H5N1 are named according to their respective differences in hemagglutinin (H) and neuraminidase (N). The Company has several preclinical candidates under development for the treatment of influenza infection. CC-42344, a novel PB2 inhibitor, has been selected as a preclinical lead. This candidate binds to a highly conserved PB2 site of the influenza polymerase (PB1: PB2: PA), and exhibits a novel mechanism of action. CC-42344 showed excellent antiviral activity against influenza A strains, including avian pandemic strains, and Tamiflu-resistant, Xofluza-resistant strains, and has a favorable pharmacokinetic profile. In addition to Tamiflu, an approved antiviral product candidate that is a competitor for the Company’s influenza programs, S-033188, being developed by Shionogi/Roche. S-033188 was approved as Xofluza in Japan on February 23, 2018, and in the US as baloxavir marboxil (trade name Xofluza ® ) on October 24, 2018. See “Item 1 – Business – Research and Development Update – Influenza” for more information. Xofluza-resistant strains emerged in both the US and Japan within several months of Xofluza being on the market. Coronavirus: COVID-19 continues to be a global pandemic fueled by an emergence of new strains . COVID-19 continues to be a global pandemic with 117,332,262 confirmed cases globally, including 2,605,356 deaths, as of March 10, 2021, according to the data reported by the World Health Organization. The COVID-19 pandemic and the measures taken by the federal, state and foreign governments to stop the spread of the virus have caused a significant disruption to the U.S. and global economy. Coronaviruses (CoV) are a large family of viruses that historically have been associated with illness ranging from mild symptoms similar to the common cold to more severe respiratory disease. Infection with the novel SARS-CoV-2 has been associated with a wide range of responses, from no symptoms to more severe disease that has included pneumonia, severe acute respiratory syndrome, kidney failure, and death. The incubation period for SARS-CoV-2 is believed to be within 14 days after exposure, with most illness occurring within about 5 days after exposure. The ability of someone with no symptoms to transmit infection to another person has heightened the public health challenge of COVID-19. On October 22, 2020, FDA approved the antiviral drug Veklury (remdesivir) for the treatment of COVID-19 requiring hospitalization. Remdesivir is a nucleotide prodrug that inhibits viral replication and was previously evaluated in clinical trials for Ebola treatment in 2014. We are aggressively pursuing the development of novel antiviral compounds for the treatment of coronavirus infections using our established proprietary drug discovery platform. By targeting the viral replication enzymes and protease, we believe it is possible to develop an effective treatment for all coronavirus diseases including COVID-19, Severe Acute Respiratory Syndrome (SARS), and Middle East Respiratory Syndrome (MERS) - coronaviruses. 7 Hepatitis C: A large competitive market with opportunity for shorter treatment regimens . HCV is a highly competitive and changing market. Currently, the standard treatment varies with the genotype of the HCV infection. Prior to late 2013, treatment included peginterferon alpha and ribavirin, along with a protease inhibitor (either telaprevir, boceprevir, or simeprevir). In late 2013, sofosbuvir, a drug belonging to a new class of drugs called “nucleoside analogs” or “Nucs,” was approved to treat HCV. In patients infected with HCV genotype 1 (the most common HCV genotype in the US), sofosbuvir was administered in combination with peginterferon alpha and ribavirin. In patients with HCV genotypes 2 and 3, however, sofosbuvir could be effectively administered in combination with ribavirin, without the need for peginterferon alpha. Since 2014, several new combinations of direct-acting antiviral agents (“DAAs”) have been approved for the treatment of HCV infection. These include Harvoni (sofosbuvir/ledipasvir) 12 weeks of treatment, Viekira Pak (ombitasvir/paritaprevir/ritonavir, dasabuvir) 12 weeks of treatment, Epclusa (sofosbuvir/velpatasvir) 12 weeks of treatment, Zepatier (elbasvir/grazoprevir) 12 weeks of treatment and Mavyret (glecaprevir/pibrentasvir) 8 weeks of treatment. We believe the next improvements in HCV treatment will be ultra-short treatments of four to six weeks, the goal of our program. We anticipate a significant global HCV market opportunity that will persist through at least 2036, given the large prevalence of HCV infection worldwide. The 2017 World Health Organization Global Hepatitis Report estimates that 71 million people worldwide have chronic HCV infections. We are targeting the viral NS5B polymerase with an NNI, which could be developed as part of an all-oral, pan-genotypic combination regimen. Our focus is on developing what is now called ultrashort treatment regimens from 4 to 6 weeks in length. Such a combination treatment CC-31244 with different classes of approved DAAs has the potential to change the paradigm of treatment for HCV with a shorter duration of treatment. Combination strategies with approved drugs could allow us to expand CC-31244 into the HCV antiviral therapeutic area globally and could lead to a high and fast cure rate, to improved compliance, and to reduced treatment duration. To our knowledge no competing company has yet developed a short HCV treatment of less than 8 weeks with a high (>95%) sustained virologic response (SVR) at week 12. CC-31244, an HCV NNI, is a potential best in class pan-genotypic inhibitor of NS5B polymerase for the treatment of HCV. The Company completed a Phase 1a/b study in Canada in September 2016, with favorable safety results in a randomized, double-blinded, Phase 1a/b study in healthy volunteers and HCV-infected subjects. The Company has completed a Phase 2a study in HCV genotype 1 subjects in the United States. Cocrystal presented the interim results from the Phase1a/b study at the APASL in February 2017. HCV-infected subjects treated with CC-31244 had a rapid and marked decline in HCV RNA levels, and slow viral rebound after treatment. Results of this study suggest that CC-31244 could be an important component in a shortened duration all-oral HCV combination therapy. Patient enrollment has been completed in the Phase 2b and the final study report filed with the FDA. See “Item 1 – Business – Research and Development Update – Hepatitis C” for more information. The Company has been seeking a partner for further clinical development of CC-31244 since completing Phase 2a trials. Norovirus: A worldwide public health problem responsible for close to 90% of epidemic, non-bacterial outbreaks of gastroenteritis around the world . Norovirus is a very common and highly contagious virus that causes symptoms of acute gastroenteritis including nausea, vomiting, stomach pain and diarrhea. Other symptoms include fatigue, fever and dehydration. Noroviruses are a major cause of gastrointestinal illness in closed and crowded environments, having become notorious for their common occurrence in hospitals, nursing homes, child care facilities, and cruise ships. In the United States alone, noroviruses are the most common cause of acute gastroenteritis, and are estimated to cause 20 million illnesses each year and contribute to 70,000 hospitalizations and 800 deaths. Noroviruses are responsible for up to 1.1 million hospitalizations and 218,000 deaths annually in children in the developing world. In immunosuppressed patients, chronic norovirus infection can lead to a debilitating illness with extended periods of nausea, vomiting and diarrhea. There is currently no effective treatment or effective vaccine for norovirus, and the ability to curtail outbreaks is limited. A few companies, including Chimerix, are developing antiviral treatments for this disease and three candidate vaccines are currently in early stages of clinical testing by GlaxoSmithKline, Ligocyte and Takeda Pharmaceuticals. By targeting viral replication enzymes and a viral protease, we believe it is possible to develop an effective treatment for all genogroups of norovirus. Also, because of the significant unmet medical need and the possibility of chronic norovirus infection in immunocompromised individuals, new antiviral therapeutic approaches may warrant an accelerated path to market. The Company is developing inhibitors of the RNA-dependent RNA polymerase and protease of norovirus. Similar to the HCV polymerases, these enzymes are essential to viral replication and is highly conserved between all noroviral genogroups. Therefore, an inhibitor of these enzymes might be an effective treatment or short-term prophylactic agent, when administered during a cruise or nursing home stay, for example. We have developed X-ray quality norovirus polymerase and protease crystals and have identified promising inhibitors. We are implementing the platform and approaches that have proven successful in our other antiviral programs. 8 Intellectual Property Our success depends, in part, upon our ability to protect our core technology. To establish and protect our proprietary rights, we rely on a combination of patents, patent applications, trademarks, copyrights, trade secrets and know-how, license agreements, confidentiality procedures, non-disclosure agreements with third parties, employee disclosure and invention assignment agreements, and other contractual rights. Our patent portfolio consists of issued patents and pending applications in the areas primarily related to the treatment of disease associated with HCV, Influenza A, Influenza B, and Norovirus/Coronavirus. In our HCV program, our patent portfolio consists of four patent families, with granted patents in the U.S. and Europe, as well as China, Canada, Eurasia, Japan, and Singapore. Applications are pending in numerous other jurisdictions. In our Influenza A program, our patent portfolio consists of four patent families, including two pending international (PCT) applications and two families of pending applications in the U.S. and various foreign countries.

Aspects of this program are developed in collaboration with Merck. In our Norovirus and Coronavirus programs, our patent portfolio consists of three pending families of U.S. provisional applications, and a portfolio of patent families licensed through KSURF. Collaborations Merck Collaboration On January 2, 2019, we entered into an Exclusive License and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck to discover and develop certain proprietary influenza A/B antiviral agents. Under the terms of the Collaboration Agreement, Merck is funding research and development for the program at Cocrystal and Merck, including clinical development at Merck, and Merck is responsible for worldwide commercialization of any products derived from the collaboration. The Company received an upfront payment of $4,000,000 in January 2019 and is eligible to receive milestone payments related to designated development, regulatory and sales milestones with the potential to earn up to $156,000,000, as well as royalties on product sales. The Collaboration Agreement operates under a Research Operating Plan (ROP) which includes goals for both organizations. In January 2021, the Company announced it had completed all research obligations under the Merck exclusive worldwide license and collaboration agreement, and that Merck is now solely responsible for further development of the influenza A/B antiviral compounds that were discovered in the collaboration using Cocrystal’s unique structure-based technologies and Nobel Prize-winning expertise. Kansas State University Research Foundation Cocrystal entered into a License Agreement with KSURF on February 18, 2020 to further develop certain proprietary broad-spectrum antiviral compounds for the treatment of Norovirus and Coronavirus infections. 9 Pursuant to the terms of the License Agreement, KSURF granted the Company an exclusive royalty bearing license to practice under certain patent rights, under patent applications covering antivirals against coronaviruses, caliciviruses, and picornaviruses, and related know-how, including to make and sell therapeutic, diagnostic and prophylactic products. The Company agreed to pay KSURF a one-time non-refundable license initiation fee of $80,000 under the License Agreement, and annual license maintenance fees. The Company also agreed to make certain future milestone payments of up to approximately $3.1 million, dependent upon the progress of clinical trials, regulatory approvals, and initiation of commercial sales in the United States and certain countries outside the United States. On April 19, 2020, the Company entered into a second License Agreement with KSURF in addition to the License Agreement entered into in February 2020. Pursuant to the terms of the second License Agreement, KSURF granted the Company an exclusive royalty bearing license to practice under certain patent rights under patent applications covering antivirals against coronaviruses, caliciviruses, and picornaviruses, and related know-how, including to make and sell therapeutic, diagnostic and prophylactic products. The Company agreed to pay KSURF a one-time non-refundable license initiation fee and annual license maintenance fees. The Company also agreed to make certain future milestone payments of up to approximately $4.2 million, dependent upon the progress of clinical trials, regulatory approvals, and initiation of commercial sales in the United States and certain countries outside the United States. Drug Discovery Collaboration with HitGen and InterX Cocrystal has a drug discovery collaboration with HitGen, a biotech company with an innovative DNA Encoded Library technology, and InterX Inc., a computer software company with a biomolecular simulation for drug discovery. The collaboration was initiated in September 2017 and has a term through August 2023. Through this collaboration, Cocrystal, HitGen and InterX scientists are applying HitGen’s DNA-encoded library (DEL) technology platform, Cocrystal’s structure-based drug discovery platform technology, and InterX’s computational science to develop novel antiviral lead candidates. The DEL technology combines the power of molecular biology, combinatorial chemistry, high throughput sequencing and advanced informatics to identify potential drug candidates. Cocrystal applies its technology to determine the cocrystal structures of the potential drug candidates identified from the DEL library. This structural information is then combined with InterX’s advanced computer algorithms to predict inhibitor-target interactions. A Joint Steering Committee comprised of representatives from all three companies is overseeing the collaboration. Competition The biotechnology and pharmaceutical industries are subject to intense and rapidly changing competition as companies seek to develop new technologies and proprietary products. We know of several companies that have marketed or are developing products for the treatment of influenza, coronavirus and HCV, including Roche, Gilead Sciences, Inc. (“Gilead”), Merck, Janssen Pharmaceuticals, Inc., Bristol-Myers Squibb, Toyama Chemical Co., Shionogi/Roche and Abbvie, Inc. Their products are widely considered effective. Further, in the wake of the global COVID-19 pandemic a number of third parties, including large biotechnology and pharmaceutical companies such as Pfizer Inc., Moderna, Inc., Janssen Pharmaceuticals, Inc., and academic institutions have been conducting research aimed at development of an effective treatment for, or a vaccine against, COVID-19. Many of the companies developing products for the viral diseases that are the focus of our programs have substantially greater financial resources, including government funding, expertise and capabilities than we do and have existing products in significantly more advanced stages of development. 10 Government Regulation Government authorities extensively regulate the research, development, testing, manufacturing and commercialization of drug products. Any product candidates we develop must be approved by the U.S. Food and Drug Administration (“FDA”) before they may be legally marketed in the U.S., and by the appropriate foreign regulatory agencies before they may be legally marketed in other countries. The clinical testing of product candidates to establish their safety and efficacy in humans is subject to substantial statutory and regulatory requirements with which we must comply. Human Capital As of December 31, 2020, we employed 13 full-time employees. Of these full-time employees, eight are engaged in research and development activities. In addition, we have contracts with Clinical Research Organizations (“CROs”), Contract Manufacturing Organizations (“CMOs”) and consultants to provide chemistry, toxicology, preclinical, clinical, and regulatory work on our programs. Corporate History The Company was formerly incorporated in Nevada under the name Biozone Pharmaceuticals, Inc. (“Biozone”). On January 2, 2014, Biozone sold substantially all of its assets to MusclePharm Corporation, and, on the same day, merged with Cocrystal Discovery, Inc.
