This double-blind active-placebo controlled trial (n=233) tested the effect of a single dose of psilocybin (25/10/1mg) with supportive therapy for treatment-resistant depression. The primary endpoint at three weeks finds a significant reduction in depressive symptoms (MADRS, 12-point drop from baseline of 32) that was significantly greater in the 25mg group vs the 1mg (placebo) group (6.6 points larger drop). The response (>50% drop in MADRS score) in the 25mg group dropped from 37% at 3 weeks to 20% at 12 weeks.
