Brief Summary:
Efficacy, Safety, and Tolerability of two administrations of COMP360 in participants with treatment-resistant depression (TRD)

Condition or disease Intervention/treatment Phase
Treatment Resistant Depression Drug: Psilocybin Phase 3

Detailed Description:

This is a phase III, international, multi-centre, randomised, parallel group, fixed repeat dose, double-blind, controlled study. The study population will include participants aged ≥18 years with TRD.

Overall, 568 participants are to be randomised in a 2:1:1 ratio to receive COMP360 25 mg, 10 mg or 1 mg.

The study will last up to 16 weeks including a three- to ten-week Screening Period and six-week follow-up from investigational product (IP) administration.

In this study, the aim is to assess the efficacy of COMP360, administered with psychological support in adult participants with TRD, in improving symptoms of depression.

Primary Outcome Measures :
  1. COMP360 25 mg versus COMP360 1 mg for the change from baseline in MADRS total score. [ Time Frame: Week 6 ]
    Montgomery-Åsberg Depression Rating Scale (MADRS) is a 10-item clinician rated scale measuring depression severity


Secondary Outcome Measures :
  1. COMP360 25 mg versus COMP360 1 mg for the change from baseline in Sheehan Disability Scale (SDS) total score. [ Time Frame: Week 6 ]
    Sheehan Disability Scale (SDS) is a brief, five-item self report inventory that assesses functional impairment in work/school, social life, and family life.
