April 17 (Reuters) - Sage Therapeutics SAGE.O said on
Wednesday it will stop development of its experimental drug to
treat Parkinson's disease after it failed a mid-stage study,
sending the company's shares down 4% before the bell.
Parkinson's disease, a progressive movement disorder of the
nervous system, affects about 1 million people in the United
States.
Sage Therapeutics' drug, dalzanemdor, did not show
statistically significant differences in patients with mild
cognitive impairment due to Parkinson's compared to a placebo,
the company said.
