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 mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
DT-101
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.
What could go wrong
This is an early-phase trial with only 118 participants, so results may not apply to everyone. The drug may not work better than placebo, and side effects are still being studied.
