NCT ID NCT04722666
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested an experimental drug called MIJ821, given as an IV infusion, to see if it could quickly reduce depression symptoms in people with major depressive disorder who also have active suicidal thoughts. About 199 adults aged 18 to 65 took part, receiving either MIJ821 or a placebo alongside standard care. The trial was terminated early, so the full results are not available.
