Aptinyx Inc Announces Temporarily Paused the Initiation of its Phase 2b Study of the 150 mg Dose of NYX-783 in Patients with Post-Traumatic Stress Disorder

Aptinyx, Inc. is a clinical-stage biopharmaceutical company. The Company is focused on the discovery, development, and commercialization of proprietary, synthetic small molecules for the treatment of brain and nervous system disorders. The Company focuses on targeting and modulating N-methyl-D-aspartate receptors, (NMDArs), which are vital to the normal and effective function of the brain and nervous system. The Company's NYX-783 is in Phase 1 clinical development for the treatment of opioid use disorder (OUD), and in preclinical development for the treatment of alcohol use disorder. NYX-783 modulates NMDA receptors to increase glutamatergic activity in key regions and may act to enhance extinction learning and alleviate the emotional symptoms of opioid withdrawal. The Company's NMDAr modulator discovery platform builds on NMDAr biology. The platform has the potential to develop into a broad pipeline and product portfolio across an array of disorders of the brain and nervous system.
