Compass Pathways plc (CMPS) filed an 8-K to disclose that its pivotal Phase 3 COMP005 study met its primary endpoint in treatment-resistant depression (TRD). In the randomized, double-blind trial (n = 258 across 32 U.S. sites), a single 25 mg dose of COMP360 psilocybin produced a statistically significant reduction in Montgomery-Åsberg Depression Rating Scale (MADRS) scores versus placebo at week 6 (mean difference −3.6 points; 95% CI [−5.7, −1.5]; p < 0.001). Safety, reviewed by the independent DSMB on 19 June 2025, was consistent with prior studies and showed no new or unexpected adverse signals, including suicidality.
COMP005 has three parts, with Parts A (through week 6) now unblinded, Part B blinded to week 26, and Part C open-label through week 52. The parallel COMP006 trial (planned n = 568) compares two fixed dosing regimens and remains blinded. The company expects to release 26-week data for COMP005 after all COMP006 participants complete Part A; 26-week COMP006 data are targeted for H2 2026.
The positive read-out strengthens CMPS’s regulatory pathway, but the FDA has not yet reviewed the data, full safety assessments are pending, and additional capital will likely be required to complete development and pursue commercialization. Forward-looking statements highlight clinical, regulatory, and financing risks.
