COCP Cocrystal Pharma Inc

Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”), announces that President and co-CEO Sam Lee, PhD will discuss progress in developing the novel, broad-spectrum PB2 inhibitor CC-42344 in an oral presentation, “Taking a new route: Development of novel inhaled and oral influenza antiviral, CC-42344” at the World Vaccine Congress West Coast on Tuesday, November 28, 2023 at 3:20 p.m. Pacific Time. The conference is being held November 27-30 at the Santa Clara Convention Center in Santa Clara, Calif.

“It is highly gratifying to be selected for an oral presentation at this prestigious gathering to discuss the significant progress we’ve made in developing CC-42344 for the treatment of pandemic and seasonal influenza A,” said Dr. Lee. “We recently announced authorization by the United Kingdom Medicines and Healthcare Products Regulatory Agency (MHRA) to initiate a Phase 2a human challenge trial with orally administered CC-42344 and we expect to begin treating influenza-infected patients later in this quarter. Additionally, preparations are underway to begin a Phase 1 clinical trial in the first half of 2024 with an inhaled CC-42344 formulation as a potential treatment and prophylaxis for influenza A.”

Following the presentation, Cocrystal will issue a press release with highlights from Dr. Lee’s discussion and the slide presentation will be available on the Company’s website.

About CC-42344 CC-42344 is an PB2 inhibitor that blocks an essential step of viral replication and was 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 certain approved influenza antivirals, while also demonstrating favorable pharmacokinetic and safety profiles.

About Seasonal InfluenzaEach year there are approximately 1 billion cases of seasonal influenza worldwide, 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. Influenza is responsible for approximately $10.4 billion in direct costs for hospitalizations and outpatient visits for adults in the U.S. annually.
