Aptinyx to Present Preclinical Data Exhibiting Effects of NYX-783 in Models of PTSD and Alcohol Use Disorder at the American College of Neuropsychopharmacology’s Annual Meeting

EVANSTON, Ill., Dec. 09, 2019 (GLOBE NEWSWIRE) -- Aptinyx Inc. (NASDAQ: APTX), a clinical-stage biopharmaceutical company developing transformative therapies for the treatment of brain and nervous system disorders, today announced a presentation highlighting preclinical data on its novel NMDA receptor modulator, NYX-783. The data exhibit robust effects of NYX-783 on conditioned fear in PTSD models and on alcohol consumption in a stress-induced alcohol seeking model. The studies were conducted in collaboration with the Medical University of South Carolina and Northwestern University. The presentation is taking place today, December 9, 2019, at the Annual Meeting of the American College of Neuropsychopharmacology in Orlando, Florida.

“We continue to observe preclinical effects of NYX-783 that strongly support its ongoing clinical development as a treatment for PTSD,” said Norbert Riedel, Ph.D., president and chief executive officer of Aptinyx. “In addition to bolstering our understanding of the positive effects of NYX-783 on learning and memory processes, these data highlight its potential utility in treating a common comorbidity of PTSD—alcohol use disorder. As we seek to understand the full therapeutic potential of NYX-783, it is very encouraging to see these data demonstrating its activity across multiple facets of such a complex condition.”

“The data observed with Aptinyx’s NYX-783 in this model are very intriguing,” said Justin T. Gass, Ph.D., assistant professor of neuroscience at the Medical University of South Carolina. “The novel mechanism of NYX-783 appears to have differentiated effects on learning and memory processes and significantly reduced stress-induced alcohol-seeking behavior in rats. Importantly, NYX-783 also significantly reduced relapse-like behavior in this model. Together, these data are supportive of further evaluation of NYX-783 and its potential utility in substance abuse conditions such as alcohol use disorder.”

About NYX-783
NYX-783 is a novel, oral NMDA receptor modulator currently in Phase 2 development for the treatment of post-traumatic stress disorder (PTSD). In preclinical studies of NYX-783, particularly strong results were observed in psychiatric models, models of fear extinction, and models of substance abuse. In a Phase 1 clinical study of NYX-783, ample central nervous system exposure was observed and the product candidate demonstrated a favorable safety and tolerability profile, with no serious adverse effects, across a wide dose range. The U.S. Food and Drug Administration has granted Fast Track designation to the development of NYX-783 for the treatment of PTSD.
