Official title

A Randomized, Double-Blind, Placebo-Controlled, Multi-Site Phase 3 Study of the Efficacy and Safety of Manualized MDMA-Assisted Psychotherapy for the Treatment of Posttraumatic Stress Disorder of Moderate or Greater Severity

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this clinical trial is to learn if MDMA-assisted therapy is safe and effective in people with at least moderate PTSD. The main question it aims to answer is: Do three sessions of MDMA-assisted therapy reduce PTSD symptoms? Researchers will compare three sessions of MDMA-assisted therapy with an initial dose of 80 to 120 mg to three sessions of placebo with therapy. Participants will undergo three preparatory sessions without any study drug, followed by three MDMA-assisted therapy or placebo with therapy sessions. Each medication session will be followed by three integrative therapy sessions without study drug.
