NCT05712187 · Major Depressive Disorder
The lead readout missed its primary endpoint. The grade and rationale below record what the trial was designed to show and what it found.
NCT05712187: The study was randomized, quadruple-blind, and placebo-controlled, with 301 participants, and used a clinical depression-symptom endpoint (MADRS). However, because the registry has no posted results, it is not possible to determine whether the primary endpoint was met.
Caveat: this result is taken from a company announcement or a news report of one, not from the trial registry or a peer-reviewed publication. Treat the figures as the sponsor's own statement, not as independently verified evidence.
