Cocrystal Pharma Presents New Data from its CC-42344 Phase 1 Influenza A Study at the 7th Annual ISIRV Antiviral Group Conference

BOTHELL, Wash., May 04, 2023 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) (Cocrystal or the Company) announces that new data from its CC-42344 Phase 1 influenza A Study was presented today by Sam Lee, Ph.D., President and co-CEO, at the 7th Annual International Society for Influenza and Other Respiratory Virus Diseases’ (ISIRV) Antiviral Group Conference.

“We are excited to present CC-42344’s promising safety, tolerability and preclinical data, including robust antiviral activity in an influenza-infected human respiratory epithelium model,” said Dr. Lee. “Our Phase 1 data continue to show this molecule’s potential as an oral therapeutic for the treatment of pandemic and seasonal influenza. Given that CC-42344 has shown sub-nanomolar potency and a novel mechanism of action with high barrier to resistance, we believe it could be used as monotherapy or in combination with other influenza antivirals. We look forward to initiating a Phase 2a influenza A human challenge study in the second half of 2023.”

The slide deck accompanying Dr. Lee’s discussion “First-in-Human Study of CC-42344, a Novel Broad-Spectrum Influenza A Polymerase PB2 Inhibitor” has been posted to the Presentations section of the company website.
