- Asia market represents one of the largest HepC virus carrier populations in the world

BOTHELL, WA, May 20, 2019 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (NASDAQ: COCP), (“Cocrystal” or the “Company”), a clinical stage biotechnology company discovering and developing novel antiviral therapeutics, announced today that it has commenced patient enrollment in its Phase 2a study in Hong Kong SAR, China.

The Phase 2a open-label study being conducted at Humanity & Health Research Centre, Humanity and Health Medical Group, in Hong Kong will evaluate the safety, tolerability and preliminary efficacy of Cocrystal’s CC-31244 in combination with Sofosbuvir and Daclatasvir with or without a protease inhibitor, for the treatment of hepatitis C (HepC). Sixteen patients will be enrolled in the Phase 2a study. This trial differs from the current Phase 2a trial Cocrystal is conducting in that testing will include for the first time a protease inhibitor.

Dr. George Lau commented, “We are pleased to commence patient enrollment in this important, differentiated Phase 2a study. I believe CC-31244 has the potential to be a shorter, safer and more effective treatment option for treating hepatitis C in the Asian population and where there remains a significant unmet need.”

Gary Wilcox, Chairman and Chief Executive Officer of Cocrystal stated, “The commencement of patient enrollment in this Phase 2a study represents a noteworthy accomplishment in our clinical development program for CC-31244. We are pleased to be working with the Humanity & Health Research Centre in Hong Kong and believe this study will provide valuable insight in this important market, representing one of the largest hepatitis C virus carrier populations in the world. We look forward to further understanding the potential to change the treatment paradigm for patients living with HCV by providing an ultra-short therapy to enhance the existing HepC combination therapies.”

Under the Clinical Trial Agreement, the Phase 2a study of CC-31244 for the treatment of HepC will be sponsored and conducted by the Humanity & Health Research Centre, Hong Kong under the guidance of George Lau, M.D., FRCP (Edin, Lond), FHKAM (Med), FHKCP, FAASLD, Founding Chairman of Humanity and Health Medical Group, Hong Kong. As part of the agreement, Cocrystal will provide CC-31244, its lead product in development for HepC. Cocrystal’s CC-31244 is an investigational, oral, potent, broad-spectrum replication inhibitor called a non-nucleoside inhibitor (NNI). It has a high barrier to drug resistance designed and developed using the Company's proprietary structure-based drug discovery technology. It is active against HCV genotypes 1-6 with no significant cytotoxicity in multiple cell types at high concentrations.
