Aptinyx Inc. (NASDAQ: APTX), a clinical-stage biopharmaceutical company developing transformative therapies for the treatment of brain and nervous system disorders, today announced upcoming presentations highlighting preclinical data on its novel NMDA receptor modulator, NYX-458, at the AD/PD 14th International Conference on Alzheimer’s & Parkinson’s Diseases in Lisbon, Portugal.

“We are excited to present these data, demonstrating the striking effects that NYX-458 has on cognitive impairment in a highly translatable non-human primate model of Parkinson’s disease,” said Cassia Cearley, Ph.D., vice president of research at Aptinyx. “Across the cognitive assessments used in the study, NYX-458 demonstrated rapid, robust, and enduring reversal of cognitive impairment. On some measures, cognitive performance was restored to healthy baseline levels. We are highly encouraged by these data and are working to advance NYX-458 in clinical development and toward patients that need better therapeutic options.”

About NYX-458NYX-458 is a novel, oral NMDA receptor modulator currently in Phase 1 clinical development for the treatment of cognitive impairment associated with Parkinson’s disease. In preclinical studies in rodents and non-human primates, NYX-458 has demonstrated rapid, robust, and enduring effects on cognitive impairment. A Phase 1 study evaluating the safety, tolerability, pharmacokinetics, and CNS exposure of NYX-458 is ongoing, and Aptinyx expects to report data from the study in the first half of 2019.

About AptinyxAptinyx Inc. is a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of proprietary synthetic small molecules for the treatment of brain and nervous system disorders. Aptinyx has a platform for discovery of novel compounds that work through a unique mechanism to modulate – rather than block or over-activate – NMDA receptors and enhance synaptic plasticity, the foundation of neural cell communication. The company has three product candidates in clinical development in central nervous system indications, including chronic pain, post-traumatic stress disorder, and cognitive impairment associated with Parkinson’s disease. Aptinyx is also advancing additional compounds from its proprietary discovery platform, which continues to generate a rich and diverse pipeline of small-molecule NMDA receptor modulators with the potential to treat an array of neurologic disorders.
