Aptinyx Reports Results from Phase 2 Study of NYX-458 in Cognitive Impairment Associated with Parkinson's Disease and Dementia with Lewy Bodies and Provides Pipeline and Corporate Update

 

NYX-458 did not demonstrate sufficient efficacy in the Phase 2 study to support further development by Aptinyx

 

The company will undertake cost-cutting measures and explore strategic alternatives

 

The company will terminate its ongoing study of NYX-783 in PTSD and analyze the data available to date

 

EVANSTON, Ill., February 27, 2023 -- Aptinyx Inc. (Nasdaq: APTX), a clinical-stage biopharmaceutical company developing transformative therapies for the treatment of brain and nervous system disorders, today announced results from a Phase 2 clinical study evaluating the effects of NYX-458 in patients with cognitive impairment associated with Parkinson’s disease and dementia with Lewy bodies. Across the overall study population, NYX-458 did not demonstrate clinically meaningful improvements over placebo on the study’s efficacy endpoints. The results do not support further development of NYX-458 by the company.

 

“We are very disappointed that the results of this Phase 2 study did not validate the therapeutic potential observed previously in preclinical studies of NYX-458 in models of cognitive impairment,” said Andy Kidd, M.D., president and chief executive officer of Aptinyx. “We appreciate the dedication and contributions of patients, investigators, and the extensive team that worked on the study. We intend to focus our efforts on maximizing the value of our assets, closing our study of NYX-783 in PTSD to enable an early analysis of the data, and exploring strategic alternatives to support the advancement of our NMDA receptor modulation platform.”

 

The first-in-patient Phase 2 study was a randomized, double-blind, parallel-design, placebo-controlled study in 99 patients with mild cognitive impairment or mild dementia associated with Parkinson’s disease or Dementia with Lewy Bodies. The study evaluated daily oral dosing of a 30 mg dose level of NYX-458 compared to placebo over a 12-week period. Across the overall study population, NYX-458 did not demonstrate clinically meaningful improvements over placebo on the study’s efficacy endpoints. These endpoints evaluated everyday function using the Penn Parkinson’s Daily Activities Questionnaire (PDAQ-15) and the Everyday Cognition-12 Scale (ECog-12), as well as cognitive performance using a battery of computerized neurocognitive tests. NYX-458 was well-tolerated in the study. The results overall do not support further advancement of the development program by Aptinyx.

 

The company intends to undertake cost-cutting measures to preserve capital and support the exploration of strategic alternatives. Consistent with these measures, the company will terminate its ongoing Phase 2b study of NYX-783 in post-traumatic stress disorder (PTSD) and analyze the data to date to inform the next steps for the program.
