What this trial studies

This Phase 2 randomized, placebo-controlled trial examines the safety and potential effectiveness of DT-101 as an adjunct therapy for adults with major depressive disorder who are already on antidepressant treatment. Participants will be randomly assigned to receive DT-101 or placebo for 8 weeks, with regular clinic visits, health checks, and questionnaires to monitor symptoms and tolerability. Blood and urine samples will be collected to study how the drug is absorbed and processed in the body. The study includes screening assessments to confirm eligibility and safety before starting treatment. Results will be analyzed to see if DT-101 provides additional relief from depressive symptoms beyond standard care.

Why it matters

Potential benefit: If successful, DT-101 could offer additional relief from depressive symptoms when added to current treatment for adults with MDD.

How similar studies have gone: Past studies with similar adjunctive approaches in depression have shown mixed results; this study explores DT-101 specifically as an adjunctive therapy.
