• Expects to report topline results in 2025 from Phase 2a influenza A human challenge study with oral CC-42344, including initial indication of virology
• In vitro testing shows CC-42344 inhibits the avian influenza A (H5N1) PB2 protein recently identified in U.S. dairy cows
• Expects to report topline results in late 2024 or early 2025 from Phase 1 study with oral CDI-988, the first potential pan-coronavirus/pan-norovirus oral antiviral
• Plans to initiate Phase 1 study in 2025 with inhaled CC-42344, a potential influenza treatment and post-exposure prophylactic

BOTHELL, Wash., Aug. 14, 2024 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) reports financial results for the three and six months ended June 30, 2024, and provides updates on its antiviral product pipeline, upcoming milestones and business activities.

“We are rapidly approaching major inflection points in our clinical programs,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal. “In the coming months we expect to report topline results from our Phase 2a study with PB2 inhibitor CC-42344 including an initial indication of virology in humans infected with the influenza A virus. Our plan is to file an Investigational New Drug (IND) application in 2025 to conduct our next study in the U.S. We further validated CC-42344’s broad-spectrum activity through in vitro testing demonstrating it inhibits the new, highly pathogenic avian flu PB2 protein identified as infecting U.S. dairy cows. We also are preparing to initiate a Phase 1 study in healthy volunteers as the first clinical step in evaluating inhaled CC-42344 as a potential prophylactic and therapeutic for influenza A.

“Preparations are underway to begin the multiple-ascending dose portion of the first-in-human study with our pan-norovirus/pan-coronavirus oral protease inhibitor CDI-988, following favorable safety and tolerability data from the single-ascending dose (SAD) portion of this study,” said Dr. Lee. “We expect to report topline results from the full study in late 2024 or early 2025.”

“I’m pleased to report that through our cost-efficient business model, we expect our cash to be sufficient to advance our planned development programs through the coming 12 months,” said James Martin, CFO and co-CEO of Cocrystal.

Antiviral Product Pipeline Overview

We apply our proprietary structure-based drug discovery platform technology for developing broad-spectrum antivirals that inhibit 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 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 showed 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 authorization from United Kingdom Medicines and Healthcare Products Regulatory Agency (MHRA) for an oral CC-42344 Phase 2a human challenge study.
  • In December 2023 we began a randomized, double-blind, placebo-controlled Phase 2a 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 study design, drug manufacturing and nonclinical studies necessary to file a Phase 2b study design.
  • In May 2024 we completed enrollment in the Phase 2a human challenge study.
  • In June 2024 we reported that in vitro testing showed CC-42344 inhibited the activity of the highly pathogenic avian influenza A (H5N1) PB2 protein that was identified as infecting U.S. dairy cows.
  • We expect to report topline results from the Phase 2a human challenge study in 2024 and to plan to file an IND application in 2025 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 2025.
• Influenza A/B Program
  • Preclinical lead development of novel influenza replication inhibitors is underway.

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 50,000 child 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 and/or short-term prophylactic for closed environments for all genogroups of norovirus.

• Oral pan-viral protease inhibitor CDI-988 for the treatment of norovirus and coronavirus infections
  • Our novel broad-spectrum protease inhibitor CDI-988 is being evaluated as a potential oral treatment for noroviruses and coronaviruses.
  • 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 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 our selection of CDI-988 as our lead for the 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.
  • In July 2024 we reported favorable safety and tolerability results from the SAD cohorts in the Phase 1 study.
  • We expect to report topline results from the CDI-988 Phase 1 study in late 2024 or early 2025.

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). CDI-988 showed potent in vitro pan-viral activity against common human coronaviruses, rhinoviruses and respiratory enteroviruses, as well as against noroviruses. 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
  • CDI-988 exhibited superior in vitro potency against SARS-CoV-2 and demonstrated a favorable safety profile and PK properties.
  • 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.
  • In July 2024 we reported favorable safety and tolerability results from the SAD cohorts in the Phase 1 study.
  • We expect to report topline results from the CDI-988 Phase 1 study in late 2024 or early 2025.
