The contribution of patient support to psilocybin's antidepressant effects remains uncertain. Relationships between therapeutic alliance (Scale to Assess Therapeutic Relationship-Patient version; STAR-P), psychedelic experience (Five-Dimensional Altered States of Consciousness Questionnaire and Emotional Breakthrough Inventory; 5D-ASC and EBI) and clinical outcomes (Montgomery-Åsberg Depression...

Background: The largest randomized study of psilocybin to date demonstrated the efficacy of COMP360 25 mg (Compass Pathways' investigational proprietary pharmaceutical-grade synthesized psilocybin formulation) in participants with treatment-resistant depression (COMP 001), compared with 10 mg and 1 mg doses. Here, we report findings from COMP 004, a 52-week observational follow-up of patients...

To determine the relationships between psilocybin dose, psychedelic experiences, and therapeutic outcome in treatment-resistant depression. For treatment-resistant depression, 233 participants received a single dose of 25, 10, or 1 mg of COMP360 psilocybin (a proprietary, pharmaceutical-grade synthesized psilocybin formulation, developed by the sponsor, Compass Pathfinder Ltd.) with...

It has been suggested that the recent use and discontinuation of antidepressant drugs compromises the action of psilocybin. As evidence is only available from small or uncontrolled samples, this post hoc analysis investigated this using data from the largest, phase II, randomized controlled trial of psilocybin treatment to date. Data from 233 participants with treatment-resistant depression...

Psilocybin is being investigated as a treatment in adults with treatment-resistant depression (TRD). Withdrawal from serotonergic antidepressant drugs is a common prerequisite for taking part in trials of psilocybin due to the possibility of ongoing antidepressant drugs altering the psychedelic effect. This phase II, exploratory, international, fixed-dose, open-label study explored the safety,...

Three weeks after dosing, psilocybin 25 mg and, to a lesser degree, 10 mg improved measures of patient-reported depression severity, anxiety, affect, and functioning. These results extend the primary findings from the largest randomised clinical trial of psilocybin for TRD to examine other outcomes that are of importance to patients.

Psilocybin is being studied for use in treatment-resistant depression. In this phase 2 double-blind trial, we randomly assigned adults with treatment-resistant depression to receive a single dose of a proprietary, synthetic formulation of psilocybin at a dose of 25 mg, 10 mg, or 1 mg (control), along with psychological support. The primary end point was the change from baseline to week 3 in the...
