COMPASS Pathways' psilocybin compound COMP360 is on track to become the first psychedelic drug approved by the FDA, likely for treatment-resistant depression — meaning millions of people who don't respond to antidepressants would have a new legal option.
COMP360 achieved Phase 3 primary endpoint for TRD. FDA issued National Priority Voucher. FDA Commissioner Makary expects decision by late summer/fall 2026. Breakthrough Therapy designation + Phase 3 success + Priority Voucher + Commissioner statement = approval is base case. 87% reflects residual uncertainty around Advisory Committee, label negotiation, REMS.
