New pill aims to keep depression away longer
NCT ID NCT07196501
First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This Phase 3 study tests whether adding NBI-1065845 to standard antidepressants can delay the return of depressive symptoms in adults with major depression. About 550 people who have not fully responded to current antidepressants will take either the study drug or a placebo pill. The main goal is to see how long it takes for depression symptoms to come back.

- What this could lead to
- If it works, this could provide a new add-on option to help people with major depression stay well longer and delay relapse.
- What could go wrong
