BOTHELL, Wash., June 05, 2025 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) announces that its broad-spectrum protease inhibitor CDI-988 will be featured in an oral presentation at the 2025 Military Health System Research Symposium (MHSRS) being held August 4-7 in Kissimmee, Fla. Cocrystal is developing CDI-988 as a norovirus prophylaxis and treatment. Sam Lee, PhD, the Company’s President and co-CEO, will discuss Phase 1 results during the Broad-Spectrum Anti-Viral Countermeasures breakout session on August 4, 2025.

“I am pleased to be discussing CDI-988 at this prestigious conference that showcases innovative antiviral agents to treat militarily relevant pathogens,” said Dr. Lee. “Norovirus is a leading cause of acute gastroenteritis worldwide for which there are no approved antiviral agents or vaccines. Norovirus spreads rapidly through confined spaces such as in ships or other military settings, and can inflict severe vomiting and diarrhea, posing a potential threat to operational effectiveness and a significant economic burden.

“Cocrystal developed CDI-988 as a potential breakthrough for norovirus prophylaxis and treatment using our proprietary structure-based platform technology. Unlike conventional antivirals, it targets the virus' core replication machinery, halting infection at early stages regardless of viral strain or mutation,” he added. “We believe CDI-988 could transform how norovirus outbreaks are prevented and treated.”

Pan-Viral Inhibitor CDI-988

CDI-988 was designed and developed as a broad-spectrum inhibitor to a highly conserved region in the active site of 3CL viral proteases. Based on a novel mechanism of action and superior broad-spectrum antiviral activity, CDI-988 represents a compelling first-in-class oral treatment for both noroviruses and coronaviruses. Cocrystal has completed a single-center, randomized, double-blind, placebo-controlled Phase 1 study in healthy adults evaluating the safety, tolerability and pharmacokinetics of CDI-988, including a food effect cohort.

Structure-Based Platform Technology

Cocrystal’s proprietary structural biology, along with its expertise in enzymology and medicinal chemistry, enable its development of novel antiviral agents. The Company’s platform provides a three-dimensional structure of inhibitor complexes at near-atomic resolution, providing immediate insight to guide Structure Activity Relationships. This helps to identify novel binding sites and allows for a rapid turnaround of structural information through highly automated X-ray data processing and refinement. The goal of this technology is to facilitate the development of best-in-class antiviral therapies that have fast onset of action or shortened treatment time, are safe, well tolerated and easy to administer; and are effective against all viral subtypes that cause disease and have a high barrier to viral resistance.
