Cocrystal Pharma Granted European Patent Covering Oral Antiviral Candidate CC-42344 in Combination with Another Antiviral Agent for the Treatment of Influenza

BOTHELL, Wash., Nov. 01, 2022 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) announces it has been granted European patent EP3866778 titled "Combinations Of Inhibitors of Influenza Virus Replication,” which covers the Company’s broad-spectrum oral PB2 inhibitor CC-42344 in combination with approved influenza antiviral drugs including Tamiflu®, Xofluza® or Favipiravir. Cocrystal recently announced the completion of enrollment in a Phase 1 study with CC-42344 for the treatment of pandemic and seasonal influenza A, with topline study results expected later this year.

“This new patent provides meaningful protection for our PB2 clinical program in the European Union and is the first to be granted as we pursue a similar patent strategy in other jurisdictions,” said James Martin, Cocrystal’s CFO and interim Co-CEO. “The granting of this patent is an important step in our efforts to expand protection of our novel, best-in-class antiviral candidates both in the U.S. and internationally.”

About CC-42344 and Influenza
CC-42344 is an oral PB2 inhibitor discovered using Cocrystal’s proprietary structure-based drug discovery platform technology. It is specifically designed to be effective against all significant pandemic and seasonal influenza A strains and to have a high barrier to resistance due to the way the virus’ replication machinery is targeted. CC-42344 targets the influenza polymerase, an essential replication enzyme with several highly essential 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®, while also demonstrating favorable PK and safety profiles.

According to a June 2022 report by Precision Reports, the global influenza therapeutics market is projected to reach $9.5 billion by 2027, up from $6.6 billion in 2020 and growing at a 4.8% CAGR between 2021 and 2027.
