Sage Therapeutics Faces Challenges Amid Dalzanemdor Failures and Strategic Shifts
Sage Therapeutics has decided to halt the development of dalzanemdor following a string of unsuccessful phase 2 trials, most recently involving cognitive impairment associated with Huntington’s disease. The drug failed to show any significant improvement over placebo in cognitive function, visual attention, task switching, or daily life experiences in these trials[1][3]. Despite there being no new safety issues, dalzanemdor's discontinuation comes after similar failures in earlier trials for Alzheimer's and Parkinson's diseases. This setback has resulted in the termination of current studies, including the PURVIEW study focused on dalzanemdor's safety in Huntington’s disease, leading to significant layoffs within Sage's research and development team[2][3].
