Randomized, Double-blind Study of ALTO-207 Versus Placebo in Adults Aged 18 to 75 With Treatment-resistant Depression

What this Trial Is About

Researchers are evaluating ALTO-207 compared to a placebo in adults with treatment-resistant depression TRD to measure changes in depressive symptoms. This phase 2 trial aims to better understand the effects of ALTO-207 on depression severity in participants who have not responded well to previous antidepressant treatments. Participants will be randomly assigned to receive either ALTO-207 twice daily or a matching placebo. The study is double-blind and placebo-controlled, ensuring that neither participants nor researchers know who receives the active drug or placebo. The treatment period lasts up to 8 weeks, during which changes in depressive symptoms will be closely monitored. During the study, participants will undergo assessments including the Montgomery-sberg Depression Rating Scale MADRS to track changes in depression severity from the start through 8 weeks. Additional evaluations include response rates and clinical global impressions of severity over time. Safety and symptom monitoring will occur throughout, and participation may last up to 8 weeks based on treatment and follow-up visits.
