A Multi-Site Open-Label Safety Extension Study of Manualized MDMA-Assisted Psychotherapy for the Treatment of Participants With Posttraumatic Stress Disorder

Resilient Pharmaceuticals·interventional·Posted Jan 19, 2021·Updated Jun 6, 2025

In Brief

A Phase 3 clinical trial evaluating Midomafetamine HCl for PTSD. Completed, enrolled 87 participants across 15 sites in 3 countries.

Detailed Summary

The goal of this clinical trial is to learn if MDMA-assisted therapy is safe and effective at reducing PTSD symptoms in people with PTSD who received placebo in a prior MDMA-assisted therapy study. The main question it aims to answer is: Do PTSD symptoms decrease in people who receive a flexible dose of MDMA (120 or 180 mg MDMA HCl) with therapy in three sessions? Participants will undergo three preparatory therapy sessions without any study drug, then three MDMA-assisted therapy sessions with a flexible dose of 80 or 120 mg, followed by three integrative therapy sessions without study drug after each MDMA-assisted therapy session.
