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.
