Cocrystal Pharma Reports Favorable Preliminary Data from Phase 1 Initial Cohorts with CC-42344, a Novel, Broad-Spectrum Influenza A antiviral

CC-42344 administered orally as a single 100 mg or 200 mg dose in healthy adults showed a favorable safety and pharmacokinetic profile

BOTHELL, Wash., April 12, 2022 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) reported preliminary results of a Phase 1 study with CC-42344, demonstrating a favorable safety and pharmacokinetic profile. CC-42344 is a broad-spectrum oral antiviral for the treatment of pandemic and seasonal influenza A with a novel mechanism of action.

The ongoing Phase 1 clinical trial plans to enroll 56 healthy adults. Results from the first two single-ascending dose 100 mg and 200 mg cohorts showed a favorable pharmacokinetic profile of CC-42344. To date, CC-42344, has demonstrated excellent oral bioavailability, dose-dependent plasma exposures, and a half-life supportive of oral daily dosing. The Phase 1 study is designed to evaluate CC-42344 administered in single-ascending and multiple-ascending doses. Cocrystal expects to report full results from the study in 2022.

“Today’s update reinforces Cocrystal’s progress in developing best-in-class antiviral medicines. Influenza is one of the most serious worldwide public health threats. Important concerns remain about the emergence of pandemic strains and resistance to available drugs. We are encouraged by the safety and pharmacokinetic profile observed to date with single oral doses of CC-42344 and look forward to initiating the next portion of the trial,” said Sam Lee, Ph.D., Cocrystal’s President and co-interim CEO. “Based on a novel mechanism of action and high barrier to resistance, we believe CC-42344 could provide a potentially best-in-class oral candidate for the treatment of pandemic and seasonal influenza infection.”

About CC-42344
CC-42344 is an oral 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, including pandemic 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 pharmacokinetic and safety profiles.
