NCT ID NCT07610473
First seen Jun 25, 2026 · Last updated Sep 03, 2026 · Updated 9 times
Summary
This phase 2 trial tests whether DT-101 can ease depression symptoms in adults with major depressive disorder who are already on antidepressant medication. About 118 participants will receive either DT-101 or a placebo, and researchers will track changes in depression scores over 56 days. The goal is to see if DT-101 offers additional benefit beyond standard treatment.

- What this could lead to
- If it works, this could provide a new treatment option for people with major depressive disorder who are already on medication.
