Cocrystal Pharma Inc. announced it has engaged hVIVO, to conduct a Phase 2a clinical trial with the Company's novel, broad-spectrum, orally administered antiviral candidate CC-42344. This candidate represents a new class of investigational medicine designed to directly inhibit replication of the virus for the treatment of pandemic and seasonal influenza A. The single-center, double-blind, placebo-controlled Phase 2a human challenge trial is designed to evaluate safety, viral and clinical measures of orally administered CC-42344 to subjects challenged with influenza A. The trial is expected to be initiated in the second half of 2023, pending approval from the United Kingdom Medicines and Healthcare Products Regulatory Agency. This study will be conducted at hVIVO's facility in the United Kingdom.

Cocrystal is conducting a Phase 1 study with CC-42344 in healthy subjects in Australia. The Company recently announced pharmacokinetic (PK) data supporting once-daily dosing from the single-ascending dose portion of this study. Enrollment in the multiple-ascending dose portion of the Phase 1 trial is ongoing, with full trial results expected in 2022.
