BOTHELL, Wash. (May 13, 2024)Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) reports financial results for the three months ended March 31, 2024, and provides updates on its antiviral product pipeline, upcoming milestones and business activities.


“The coming months promise to be exceptionally eventful with major inflection points in our dual norovirus-coronavirus and influenza programs expected this year,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal. “Among these, we expect topline results from the SAD portion of a first-in-human study with our pan-coronavirus and pan-norovirus oral protease inhibitor CDI-988, with the multiple ascending dose (MAD) portion of this study expected to begin in the second half of 2024.


“In our Phase 2a human challenge study with our novel broad-spectrum oral PB2 inhibitor CC-42344 for pandemic and seasonal influenza A, we expect to report topline results and to prepare an IND application to conduct a late-stage clinical study in the U.S. in the second half of 2024,” Dr Lee added. “Also in our influenza program, preparations are underway to initiate a Phase 1 study in healthy volunteers with inhaled CC-42344 as a potential prophylactic and therapeutic for influenza A in the second half of this year.”


“We continue advancing our development programs in high-value indications through a cost-efficient business model,” said James Martin, CFO and co-CEO of Cocrystal. “We anticipate significant milestones this year and expect our cash will be sufficient to fund operating activities beyond the next twelve months as we tightly manage our financial resources.”


Antiviral Product Pipeline Overview


We apply our proprietary structure-based drug discovery platform technology for developing broad-spectrum antivirals that inhibit the viral replication. By designing and selecting antiviral drug candidates that target the highly conserved regions of the viral enzymes, we seek to develop drugs that are effective against the virus and mutations of the virus, and also have reduced off-target interactions that may cause undesirable side effects. Our drug discovery process differs from traditional, empirical medicinal chemistry approaches that often require iterative high-throughput compound screening and lengthy hit-to-lead processes.




Influenza Programs


Influenza is a major global health threat that may become more challenging to treat in the future due to the emergence of highly pathogenic avian influenza viruses and resistance to approved influenza antivirals. Each year there are approximately 1 billion cases of seasonal influenza worldwide, 3-5 million severe illnesses and up to 650,000 deaths, according to the World Health Organization. On average, about 8% of the U.S. population contracts influenza each season. In addition to the health risk, influenza is responsible for approximately $10.4 billion in direct costs for hospitalizations and outpatient visits for adults in the U.S. annually.


Oral CC-42344 for the treatment of pandemic and seasonal Influenza A infections
 Our novel PB2 inhibitor CC-42344 has shown excellent in vitro antiviral activity against pandemic and seasonal influenza A strains, as well as strains that are resistant to Tamiflu® and Xofluza®.
 In March 2022 we initiated enrollment in a randomized, double-blind, dose-escalating Phase 1 study to evaluate the safety, tolerability and pharmacokinetics (PK) of oral CC-42344 in healthy adults.
 In July 2022 we reported PK results from the SAD portion of the study that support once-daily dosing.
 In December 2022 we reported favorable safety and tolerability results from the oral CC-42344 Phase 1 study.
 In April 2023 we received approval from UK MHRA for oral CC-42344 Phase 2a study.
 In December 2023 we began a randomized, double-blind, placebo-controlled Phase 2a human challenge study to evaluate the safety, tolerability, viral and clinical measurements of CC-42344 in influenza A infected subjects.
 In March 2024 we received feedback from the FDA on a Pre-IND package improving clarity on clinical trial design, drug manufacturing and nonclinical studies necessary to file a Phase 2b trial design.
 In May 2024 we completed enrollment in the Phase 2a human challenge study.
 In the second half of 2024 we expect to report topline results from the Phase 2a human challenge study and to prepare an IND application to conduct a late-stage study in the U.S.


Inhaled CC-42344 for the treatment of pandemic and seasonal Influenza A infections
 GLP toxicology study is underway with inhaled CC-42344 as a potential therapeutic and post-exposure prophylaxis for influenza A. CC-42344 has exhibited superior pulmonary exposure in preclinical studies.
 We expect to begin a Phase 1 study with inhaled CC-42344 in Australia in the second half of 2024.


Influenza A/B Program
 Preclinical lead development of novel influenza replication inhibitors is underway.


COVID-19 and Other Coronavirus Programs


By targeting viral replication enzymes and protease, we believe it is possible to develop effective treatments for all diseases caused by coronaviruses including COVID-19, Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). Our SARS-CoV-2 protease inhibitors showed potent in vitro pan-viral activity against common human coronaviruses, rhinoviruses, and respiratory enteroviruses, as well as against noroviruses that can cause symptoms of acute gastroenteritis. Driven by the anticipated emergence of new COVID-19 variants, the global COVID-19 therapeutics market is estimated to exceed $16 billion by the end of 2031.


Oral Pan-viral Protease Inhibitor CDI-988 for the treatment of coronaviruses and noroviruses
 Our novel broad-spectrum protease inhibitor CDI-988 is being evaluated as a potential oral treatment for coronaviruses and noroviruses. CDI-988 exhibited superior in vitro potency against SARS-CoV-2 and noroviruses, and demonstrated a favorable safety profile and PK properties.
 In May 2023 we announced approval of our application to the Australian regulatory agency for a randomized, double-blind, placebo-controlled Phase 1 study to evaluate the safety, tolerability and PK of oral CDI-988 in healthy volunteers.
 In August 2023 we announced the selection of CDI-988 as our lead oral candidate for norovirus, in addition to coronavirus.
 In September 2023 we dosed the first subject in our dual norovirus-coronavirus oral CDI-988 study, which is expected to serve as a Phase 1 study for both indications.
 We expect to report SAD cohort topline results from the Phase 1 study with CDI-988 in the second quarter of 2024.




Norovirus Program


Norovirus is a highly contagious infection and is the most common cause of acute gastroenteritis, accounting for nearly one in five cases. According to the Centers for Disease Control and Prevention (CDC), an estimated 685 million cases and an estimated 200,000 deaths are attributed to norovirus each year worldwide, with an estimated societal cost of $60 billion. By targeting viral replication, we believe it is possible to develop an effective treatment or short-term prophylactic for closed environments for all genogroups of norovirus.


Oral Pan-viral Protease Inhibitor CDI-988 for the treatment of norovirus infection
 CDI-988 has shown pan-viral activity against multiple norovirus strains, including the genogroup II, genotype 4 (GII.4) norovirus strain that is responsible for major norovirus outbreaks.
 In August 2023 we announced our selection of the novel broad-spectrum oral 3CL protease inhibitor CDI-988 as our lead potential oral treatment for norovirus, in addition to coronavirus.
 In September 2023 we began dosing subjects in a first-in-human study in healthy volunteers in Australia with oral CDI-988 that is expected to serve as a Phase 1 study for both indications.
 We expect to report SAD cohort topline results from the Phase 1 study with CDI-988 in the second quarter of 2024.


First Quarter Financial Results


Research and development (R&D) expenses for the first quarter of 2024 were $3.0 million, compared with $3.9 million for the first quarter of 2023. The decrease was primarily due to a reduction of clinical preparation expenses as the CC-42344 influenza product candidate moved into a Phase 2a clinical study and the CDI-988 dual norovirus-coronavirus product candidate moved into a Phase 1 clinical study. General and administrative (G&A) expenses for the first quarters of 2024 and 2023 remained consistent at $1.2 million.


Interest income for the first quarter of 2024 was $220,000 and was primarily related to interest earned on cash held in interest bearing bank accounts, with no comparable item for the first quarter of 2023. Foreign exchange loss for the first quarter of 2024 were $18,000, compared with $78,000 in the prior-year quarter, with such expenses for both quarters related to foreign currency exchange rate fluctuations.


The net loss for the first quarter of 2024 was $4.0 million, or $0.39 per share, compared with the net loss for the first quarter of 2023 of $5.2 million, or $0.64 per share.


Cocrystal reported unrestricted cash as of March 31, 2024 of $21.8 million, compared with $26.4 million as of December 31, 2023. Net cash used in operating activities for the first quarter of 2024 was $4.5 million, compared with $3.1 million for the first quarter of 2023. The Company had working capital of $22.1 million and 10.2 million common shares outstanding as of March 31, 2024.
