Feedback provides greater clarity on regulatory requirements for planned Phase 2b trial

BOTHELL, Wash., March 19, 2024 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) ("Cocrystal" or the "Company") announces it has received Pre-Investigational New Drug (Pre-IND) feedback from the U.S. Food and Drug Administration (FDA) regarding CC-42344 as a potential oral treatment for pandemic and seasonal influenza A. A Pre-IND review provides the opportunity to obtain FDA guidance and clarification on critical steps such as the proposed clinical trial design, as well as clinical drug manufacturing and nonclinical studies deemed necessary before filing the trial design. The feedback was provided in a written response to a Pre-IND package and questions submitted by the Company in January 2024.

"We value the FDA guidance as we prepare to file the IND for our Phase 2b trial and open enrollment of patients in the U.S.," said Sam Lee, Ph.D., Cocrystal's President and co-CEO. "This is an important milestone that provides greater clarity on the regulatory requirements and our planned oral CC-42344 clinical program."

A Phase 2a challenge study of oral CC-42344 is underway in the United Kingdom to evaluate safety, and viral and clinical measures in healthy volunteers who are infected with the influenza A virus. The Company expects to report topline results from this study in the second half of this year.

In addition, preparations are underway to begin a Phase 1 study in Australia with the Company's inhaled formulation of CC-42344 as a potential influenza A treatment and prophylaxis for those exposed to the virus. Recent preclinical data showed that inhaled CC-42344 exhibited highly effective delivery into the lung, superior lung exposure, efficacy in influenza-infected human lung epithelia, and a favorable safety profile.

CC-42344 Influenza A PB2 Inhibitor
CC-42344 is a novel, broad-spectrum, investigational antiviral candidate for the treatment of pandemic and seasonal influenza A. CC-42344 inhibits the first step in the viral replication process of influenza A by binding to a highly conserved PB2 site of the polymerase complex that is essential to replication. In vitro testing with CC-42344 showed excellent antiviral activity against influenza A strains, including pandemic and seasonal strains, as well as against strains resistant to Tamiflu^® and Xofluza^®, while also demonstrating favorable pharmacokinetic and safety profiles. In addition, oral CC-42344 demonstrated favorable safety and tolerability results in a Phase 1 study in Australia. This antiviral candidate was discovered using the Company's proprietary structure-based drug discovery platform technology.

About Seasonal Influenza
Each year there are approximately 1 billion cases of seasonal influenza worldwide, with 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.
