(Nasdaq: COCP) (“Cocrystal” or the “Company”) announces that initial progress of a norovirus challenge study with its direct-acting, oral protease inhibitor CDI-988 will be presented at the 39th International Conference on Antiviral Research (ICAR2026), being held April 27–May 1 in Prague, Czech Republic. CDI-988 is the first oral antiviral drug candidate under development for the prevention and treatment of acute norovirus gastroenteritis. Sam Lee, Ph.D., Cocrystal President and co-CEO, will discuss the ongoing Phase 1b challenge study evaluating CDI-988 as both a potential prophylactic and therapeutic option for norovirus infection. CDI-988 was designed and developed using the Company’s proprietary structure-based drug discovery platform technology as a pan-viral protease inhibitor, targeting 3CL viral proteases. Based on its novel mechanism of action and superior broad-spectrum antiviral activity, CDI-988 represents a potential oral treatment for both noroviruses and coronaviruses. “ICAR is widely regarded as the premier international conference for antiviral research, and it is a privilege to be selected to present our work to this antiviral research community,” said Dr. Lee. “We are excited to further advance CDI-988 into a Phase 1b norovirus challenge study at Emory University School of Medicine. CDI‑988 is our first pan-viral protease inhibitor developed for the treatment of acute norovirus gastroenteritis and also represents a significant step toward a potential treatment for patients suffering from chronic norovirus infection.” About ICAR2026 The International Society for Antiviral Research (ISAR) is an internationally recognized organization of scientists working across the basic, applied, translational and clinical aspects of antiviral research.
