Abstract excerpt

Phase II randomized double-blind controlled trial comparing two doses of psilocybin (25 mg × 2) plus 6 weeks of psychotherapy versus 6 weeks of escitalopram (10 mg/day, increased to 20 mg/day if tolerated) plus matched placebo psilocybin and matched psychotherapy in 59 patients with moderate-to-severe major depressive disorder. The primary outcome (QIDS-SR-16 change) showed numerical advantage for psilocybin but did not reach statistical significance under the pre-specified analysis. Secondary outcomes favored psilocybin. Both arms showed clinically meaningful improvement.

How to read this paper

Important clinical-context paper. Psilocybin remains Schedule I federally; this is research-supply work conducted under regulatory exemption. Don't read this as a guide to consumer use — read it for the regulatory + clinical-pathway context.
