• On track to begin a Phase 2a trial in the second half of 2023 with CC-42344 for the treatment of pandemic and seasonal influenza A
• Selected the novel protease inhibitor CDI-988 as development lead in the oral norovirus program
• CDI-988, the first potential dual coronavirus-norovirus oral antiviral, was cleared by the Australian regulatory agency for evaluation in healthy volunteers

BOTHELL, Wash., Aug. 14, 2023 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) (Cocrystal or the Company) reports financial results for the three and six months ended June 30, 2023, and provides updates on its antiviral pipeline, upcoming milestones and business activities.

“This is an eventful time for Cocrystal with notable advancements in developing our pipeline of highly promising antivirals,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal. “With our novel oral PB2 inhibitor CC-42344 for the treatment of pandemic and seasonal influenza A, we are building on the favorable data from our Phase 1 trial with the submission of an application for UK MHRA (Medicine and Healthcare Products Regulatory Agency) approval to begin a Phase 2a human challenge trial later this year.

“In our COVID-19 program, we received approval from the Australian regulatory agency in late May to begin a first-in-human trial with our novel, broad-spectrum oral protease inhibitor CDI-988. Earlier this month we announced the selection of CDI-988 as our lead oral norovirus candidate. This Phase I study is designed to access the safety, tolerability, and pharmacokinetics of CDI-988 for both our COVID-19 and our norovirus programs. We expect to report top-line data of CDI-988 Phase 1 study in 2024.”

“We have a number of significant near-term inflection points with our three leading antiviral programs including the commencement of multiple clinical trials,” said James Martin, CFO and co-CEO. “I’m pleased to report that under our cost-efficient business model, we believe our current cash position is sufficient to fund our planned operations for the next 12 months.”

Antiviral Product Pipeline Overview

We are developing therapeutics that inhibit the viral replication function of RNA viruses that cause acute and chronic diseases. Our drug discovery process focuses on the highly conserved regions of the viral enzymes and inhibitor-enzyme interactions at the atomic level. It differs from traditional, empirical medicinal chemistry approaches that often require iterative high-throughput compound screening and lengthy hit-to-lead processes. By designing and selecting antiviral drug candidates that interrupt the viral replication process and have specific binding characteristics, we seek to develop drugs that are effective against both the virus and mutants of the virus, and also have reduced off-target interactions that may cause undesirable clinical side effects.

Influenza Programs

Influenza is a severe respiratory illness caused by the influenza A or B virus that results in disease outbreaks mainly during the winter months. The global seasonal influenza market including diagnostics, treatments and vaccines is projected to reach up to $27.95 billion by 2029, according to Data Bridge Market Research.

• Pandemic and Seasonal Influenza A
  • Our novel oral PB2 inhibitor CC-42344 has shown excellent antiviral activity against influenza A strains including pandemic and seasonal strains, as well as strains that are resistant to Tamiflu^® and Xofluza^®.
  • In March 2022 we initiated enrollment in a randomized, double-controlled, dose-escalating Phase 1 trial to evaluate the safety, tolerability and pharmacokinetics (PK) of orally administered CC-42344 in healthy adults.
  • In April 2022 we announced preliminary Phase 1 trial data demonstrating a favorable safety and PK profile in the first two cohorts in the single-ascending-dose portion of the study.
  • In July 2022 we reported PK results from the single-ascending-dose portion of the study that support once-daily dosing.
  • In December 2022 we reported favorable safety and tolerability results from the CC-42344 Phase 1 trial.
  • We entered into an agreement with a UK-based clinical research organization to conduct a Phase 2a human challenge study to evaluate safety, and viral and clinical measures of orally administered CC-42344 in influenza A-infected subjects.
  • We submitted an application to the United Kingdom Medicines and Healthcare Products Regulatory Agency to conduct the Phase 2a human challenge study and, pending clearance, we expect to initiate the study in the second half of 2023.
  • Preclinical development is underway with an inhaled formulation of CC-42344 as a potential treatment and prophylaxis for influenza A. We expect to complete active pharmaceutical ingredient (API) manufacturing in preparation for toxicity studies, and to begin the Phase 1 clinical trial in the first half of 2024.
    
    
• Pandemic and Seasonal Influenza A/B Program
  
  
  • In January 2019 we entered into an Exclusive License and Research Collaboration Agreement with Merck Sharp & Dohme Corp. (Merck) to discover and develop certain proprietary influenza antiviral agents that are effective against both influenza A and B strains. This agreement includes milestone payments of up to $156 million plus royalties on sales of products discovered under the agreement.
  • In January 2021 we announced completion of all research obligations under the agreement, making Merck solely responsible for further preclinical and clinical development of these compounds.
  • In early 2023 Merck notified us of its intent to continue development of the proprietary compounds discovered under this agreement and of their filing on behalf of both companies of multiple U.S. and international patent applications associated with these compounds. Merck continues to be responsible for managing the patents.

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 main SARS-CoV-2 protease inhibitors showed potent in vitro pan-viral activity against common human coronaviruses, rhinoviruses and respiratory enteroviruses that cause the common cold, as well as against noroviruses that can cause symptoms of acute gastroenteritis.

• Oral Protease Inhibitor CDI-988
  • In August 2023 we announced the selection of CDI-988 as our lead candidate for development as a potential oral treatment for SARS-CoV-2. Designed and developed using our proprietary structure-based drug discovery platform technology, CDI-988 targets a highly conserved region in the active site of SARS-CoV-2 3CL (main) protease required for viral RNA replication.
  • CDI-988 exhibited superior in vitro potency against SARS-CoV-2 with activity maintained against variants of concern, and demonstrated a safety profile and PK properties that are supportive of once-daily dosing.
  • In May 2023 we announced approval of our application to the Australian regulatory agency for a planned randomized, double-blind, placebo-controlled Phase 1 trial in healthy volunteers.
  • We believe the FDA’s guidance for further development of our antiviral candidate CDI-45205 (described below) assists us in designing a subsequent Phase 2 trial for CDI-988.
    
    
• Intranasal/Pulmonary Protease Inhibitor CDI-45205
  
  
  • CDI-45205 is our novel SARS-CoV-2 3CL (main) protease inhibitor and was among the broad-spectrum viral protease inhibitors we obtained from Kansas State University Research Foundation (KSURF) under an exclusive license agreement announced in April 2020. We believe the protease inhibitors obtained from KSURF have the ability to inhibit the inactive SARS-CoV-2 polymerase replication enzymes into an active form.
  • CDI-45205 and several analogs showed potent in vitro activity against the main SARS-CoV-2 variants, surpassing the activity observed with the original Wuhan strain of the virus.
  • CDI-45205 demonstrated good bioavailability in mouse and rat PK studies via intraperitoneal injection, and no cytotoxicity against a variety of human cell lines. CDI-45205 also demonstrated a strong synergistic effect with the FDA-approved COVID-19 medicine remdesivir.
  • In January 2022 we received guidance from the FDA regarding further preclinical and clinical development of CDI-45205, which provides a clearer pathway for future development.
  • An IND-enabling study is ongoing with CDI-45205.

• Replication Inhibitors
  • We are using our proprietary structure-based drug discovery platform technology to discover replication inhibitors for orally administered therapeutic and prophylactic treatments for SARS-CoV-2. Replication inhibitors hold potential to work with protease inhibitors in combination therapy regimens.

Norovirus Program

• In August 2023 we announced our selection of the novel broad-spectrum 3CL protease inhibitor CDI-988 as our lead potential oral treatment for norovirus. CDI-988 is approved for evaluation in a first-in-human trial in healthy volunteers in Australia, and that trial is expected to serve as the Phase 1 trial for both our norovirus and our coronavirus programs.
• With no approved treatments or vaccines, norovirus represents a significant unmet medical need. It 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.

Hepatitis C Program

• We are seeking a partner to advance development of CC-31244 following the successful completion of a Phase 2a trial. This compound has shown favorable safety and preliminary efficacy in a triple-regimen Phase 2a trial in combination with Epclusa (sofosbuvir/velpatasvir) for the ultra-short duration treatment of individuals infected with the hepatitis C virus (HCV).
• HCV is a viral infection of the liver that causes both acute and chronic infection. The World Health Organization estimated that 58 million people worldwide had chronic HCV infection in 2019. 

Corporate Updates

• In April we announced the appointment of Fred Hassan to our Board of Directors. Mr. Hassan’s distinguished 40-year career includes serving in senior executive and director positions at global pharmaceutical companies and leading investment firms. He currently is Chairman of the investment firm Caret Group and a Director of Warburg Pincus LLC, a global private equity firm.
• In April we completed a $4.0 million private placement offering of common stock with Mr. Hassan and Phillip Frost, M.D., a Company co-founder and director, who currently is Chairman and CEO of OPKO Health.

Second Quarter Financial Results

Research and development (R&D) expenses for the second quarter of 2023 were $2.8 million, compared with $2.4 million for the second quarter of 2022. The increase was primarily due to preparations for a Phase 2a clinical trial with CC-42344 for pandemic and seasonal influenza A, and preparations for advancing CDI-988’s COVID-19 and norovirus programs toward a Phase 1 clinical trial.

General and administrative (G&A) expenses for the second quarter of 2023 were $1.5 million, compared with $1.4 million for the second quarter of 2022, with the increase primarily due to professional fees and general corporate cost increases.

The net loss for the second quarter of 2023 was $4.2 million, or $0.41 per share, compared with the net loss for the second quarter of 2022 of $24.4 million, or $3.00 per share. The second quarter of 2022 included a legal settlement of $1.6 million, which was returned to the Company in the third quarter of 2023 following a successful appeal of the trial court’s summary judgment ruling.
