PHASE1

Psilocybin-assisted CBT for Depression

Sponsor: University of California, Los Angeles

View on ClinicalTrials.gov

Summary

The primary objectives of this clinical investigation are to (1) determine the acceptability and feasibility of joining psilocybin-assisted therapy with cognitive-behavioral therapy (PA-CBT) for patients with depression, (2) optimize CBT to most effectively integrate the psilocybin experience with psychotherapy and (3) examine the clinical benefit of psilocybin as an adjunct to cognitive-behavioral therapy (CBT) for major depressive disorder. This study will involve an open trial of PA-CBT where participants will receive two doses of psilocybin (10mg and then 25mg, separated by one month) plus 12 sessions of cognitive behavioral therapy.
