Cocrystal Pharma Announces First-Patient-In for Phase 2a Human Challenge Study Evaluating Oral CC-42344 in Pandemic and Seasonal Influenza A

BOTHELL, Wash., Dec. 06, 2023 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces the achievement of first-patient-in for the Phase 2a human challenge clinical trial with CC-42344, an investigational new oral antiviral inhibitor for the treatment of pandemic and seasonal influenza A. This randomized, double-blind, placebo-controlled study will evaluate the safety, tolerability, viral and clinical measurements of influenza A infection in subjects dosed with oral CC-42344 treatment.

“There is an urgent need for new oral antivirals targeting pandemic and seasonal influenza that address drug resistance. CC-42344 was discovered using our proprietary structure-based drug discovery platform technology to inhibit the viral replication process. The data from this proof-of-concept clinical study will further validate CC-42344’s novel mechanism of action,” said Sam Lee, Ph.D., Cocrystal’s President and co-CEO. “We expect to report topline data from this clinical trial in 2024.”

“We are excited about the potential CC-42344 holds to create a paradigm shift in the treatment of one the world’s most common viral infections,” added James Martin, Cocrystal’s CFO and co-CEO. “Currently approved antiviral treatments for influenza are prone to viral resistance, increasing the need for improved influenza treatments for patients that also provide significant cost savings to the global healthcare system.”

About CC-42344
In late 2022 Cocrystal reported favorable safety and tolerability results in the single-ascending and multiple-ascending dose portions of the healthy volunteer Phase 1 trial conducted in Australia. Preclinical data showed that CC-42344 is highly active against seasonal and pandemic influenza A strains. In October 2023 Cocrystal received authorization from the United Kingdom Medicines and Healthcare Products Regulatory Agency to initiate a Phase 2a human challenge trial with CC-42344 as a potential treatment for pandemic and seasonal influenza A.

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.
