A Phase 2A, Randomized, Placebo-Controlled Clinical Study to Evaluate the Efficacy and Safety of MK-1942 Added to Stable Antidepressant Therapy in Participants With Treatment-Resistant Depression

The main purpose of this study is to assess the efficacy and safety of daily and intermittent dosing of MK-1942 compared to placebo among participants with Treatment-Resistant Depression (TRD) on a stable course of antidepressant therapy. The dual primary hypotheses of the study are that the daily MK-1942 treatment and/or intermittent MK-1942 treatment are superior to placebo in reducing Montgomery-Asberg Depression Rating Scale (MADRS) score.

 

If eligible, participants will receive the study treatment and all study-related care at no cost. Compensation will also be provided for time and travel.
