Live webcast today beginning at 10:00 a.m. ET

Aptinyx Inc. (Nasdaq: APTX), a clinical-stage biopharmaceutical company developing transformative therapies for the treatment of brain and nervous system disorders, will host a virtual portfolio review event today beginning at 10:00 a.m. ET. Presented in a live webcast format, the company will discuss its approach to the development of novel NMDA receptor modulators and review its pipeline of four clinical development programs, with particular focus on NYX-2925 in chronic pain.

NYX-2925 is an NMDA receptor positive allosteric modulator (PAM) currently under evaluation in a Phase 2b study in patients with painful diabetic peripheral neuropathy (DPN) and a Phase 2b study in patients with fibromyalgia. Today’s program will feature presentations from the Aptinyx management team as well as Richard Rauck, MD, a board-certified physician in pain medicine and anesthesiology at Carolinas Pain Institute and an investigator in the company’s ongoing Phase 2b painful DPN study. Aptinyx expects to report data from the Phase 2b painful DPN study in April or early May and anticipates reporting data from the Phase 2b fibromyalgia study in mid 2022.

The event will also highlight Aptinyx’s two other NMDA receptor PAMs currently in Phase 2 clinical development. The company’s compound, NYX-783, is in development for the treatment of post-traumatic stress disorder (PTSD). The company is conducting two Phase 2b studies of NYX-783 in patients with PTSD: the first, evaluating a 50 mg dose level, initiated in 4Q 2021; and the second, which will evaluate a 150 mg dose level, is expected to commence in 1Q 2022. Aptinyx is also developing its compound, NYX-458, for the treatment of cognitive impairment. NYX-458 is currently under evaluation in an exploratory Phase 2 study in patients with cognitive impairment associated with Parkinson’s disease and dementia with Lewy bodies. The company expects to report data from this study in 4Q 2022 or 1Q 2023.

The Aptinyx management team and Dr. Rauck will be available for Q&A following the presentations. The live webcast and accompanying presentation can be accessed on the Investor Relations section of the Aptinyx website here and a replay of the webcast will be posted following the conclusion of the event.

About NYX-2925

NYX-2925 is a novel oral NMDA receptor positive allosteric modulator currently in Phase 2 clinical development for the treatment of chronic pain. In clinical studies, NYX-2925 has demonstrated activity that affects central pain processing, resulting in alleviation of pain and other symptoms associated with chronic pain conditions. NYX-2925 has also exhibited a favorable safety and tolerability profile across a wide dose range in clinical studies to date. The U.S. Food and Drug Administration has granted Fast Track designation to Aptinyx’s development of NYX-2925 for the treatment of neuropathic pain associated with DPN.

About NYX-783

NYX-783 is a novel oral NMDA receptor positive allosteric modulator currently in Phase 2 clinical development for the treatment of post-traumatic stress disorder (PTSD). In preclinical studies of NYX-783, therapeutically relevant enhancement of extinction learning has been observed in models of conditioned fear and substance abuse. In an exploratory Phase 2 clinical study, administration of NYX-783 resulted in clinically meaningful improvements on PTSD symptoms. NYX-783 has also exhibited a favorable safety and tolerability profile across a wide dose range in clinical studies to date. The U.S. Food and Drug Administration has granted Fast Track designation to the development of NYX-783 for the treatment of PTSD.

About NYX-458

NYX-458 is a novel oral NMDA receptor positive allosteric modulator currently in Phase 2 clinical development for the treatment of cognitive impairment associated with Parkinson’s disease and dementia with Lewy bodies. NYX-458 has been shown to reverse cognitive deficits in non-human primates in a model that is highly translatable to Parkinson’s disease in humans. NYX-458 has also been shown to improve cognitive performance across various other preclinical models of neurodegeneration. In a Phase 1 clinical study, NYX-458 exhibited a favorable safety and tolerability profile across a wide dose range and achieved CNS exposures consistent with exposures observed at efficacious preclinical dose levels.
