Head-to-head evidence

Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

Next expected readout: September 2027 · NCT07592689 (registry estimate)
Psilocybin (COMP360)
Developed by COMPASS Pathways
NCT05624268 · Phase 3 · completed
This was a randomized, quadruple-blind, placebo-controlled trial with 258 participants, using change in a standard clinician-rated depression scale as the primary measure. The sponsor reports a statistically significant difference favoring COMP360 over placebo at week 6.
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.
Next expected readout: December 2026 · NCT06731621 (registry estimate)
