A Comparative Study of Sage-217 Plus an Antidepressant (ADT) Versus Placebo Plus an ADT in Adults With Major Depressive Disorder
Depressive Disorder, Major

About this trial
This is an interventional treatment trial for Depressive Disorder, Major focused on measuring Major Depressive Disorder, MDD, SAGE-217
