Cocrystal Pharma Highlights Progress with CC-42344 as a Potential Oral Treatment for Pandemic and Seasonal Influenza A at the World Antiviral Congress 2022

Affirms plans to report topline Phase 1 results in 2022 and to initiate Phase 2a influenza human challenge trial in 2023

BOTHELL, Wash., Dec. 01, 2022 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) announces that progress with CC-42344 for the treatment of pandemic and seasonal influenza A from its Phase 1 study was presented today at the World Antiviral Congress 2022 underway in San Diego. The presentation, “Novel Broad-Spectrum Influenza A PB2 Inhibitor: Clinical Update,” was delivered by Cocrystal President and co-interim CEO Sam Lee, PhD and the slides are available here.

“We appreciate the opportunity to present our antiviral drug discovery platform technology and favorable interim Phase 1 data,” said Dr. Lee. “Seasonal and pandemic influenza A continue to be major global health threats, especially given the potential for resistance against approved antivirals. Our presentation highlights potential clinical benefits for the treatment of pandemic influenza and the advantages of the oral influenza antiviral CC-42344 drug, which targets the PB2 protein of the influenza polymerase complex. We believe this novel mechanism of action holds promise against all significant influenza A strains including bird flu, while also having a high barrier to resistance. Our assessment to date also indicates that CC-42344 will have a strong synergistic effect when used with approved antivirals.”

In November 2022 Cocrystal reported that orally administered CC-42344 showed a favorable safety profile in both the single- and multiple-ascending dose portions of the Phase 1 study. The Company is currently awaiting pharmacokinetic results from this study and plans to report topline results later this year.

About CC-42344
CC-42344 is a novel PB2 inhibitor discovered using Cocrystal’s proprietary structure-based drug discovery platform technology. CC-42344 targets the influenza polymerase, an essential replication enzyme with several highly conserved regions common to multiple influenza strains. In vitro testing showed CC-42344’s excellent antiviral activity against influenza A strains, including pandemic and seasonal strains, as well as against strains resistant to Tamiflu® and Xofluza®.
