First seen Jan 04, 2026 · Last updated Apr 21, 2026 · Updated 18 times

Summary

This study is testing whether an experimental medication called ACP-211 can help adults with major depressive disorder who haven't gotten better with standard antidepressant treatments. Researchers will compare ACP-211 against a placebo (inactive pill) to see if it reduces depression symptoms more effectively. The study will also monitor for any side effects participants experience while taking the medication.
