Sage Terminates Dalzanemdor Program After Repeated Phase II Failures Across Neurological Diseases
Sage Therapeutics has made the strategic decision to halt the development of dalzanemdor after it failed to deliver promising results across multiple Phase II studies. The latest setback occurred in a trial for Huntington's disease, where dalzanemdor did not outperform a placebo in improving cognitive function, and similar failures were seen in earlier trials for Alzheimer’s and Parkinson’s diseases[1][2]. Despite no new safety concerns, the successive failures in efficacy have led Sage to terminate further development of the NMDA receptor modulator and redirect resources elsewhere[1][2]. This decision marks a significant reshaping of Sage's clinical portfolio, resulting in layoffs and a reevaluation of strategic priorities, including focussing on the launch of their postpartum depression drug, Zurzuvae[1][2].
