Official title
A Phase 2, Open-Label, Randomized Comparative Effectiveness Study for MDMA-Assisted Psychotherapy in U.S. Veterans With Chronic PTSD
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 effective in U.S. military veterans with at least moderate chronic PTSD. The main question it aims to answer is: Are two versus three MDMA-assisted therapy sessions in an outpatient treatment clinic more effective? Researchers will compare two MDMA-assisted therapy sessions to three MDMA-assisted therapy sessions. Participants will undergo three non-drug preparatory sessions prior to their first MDMA-assisted therapy session. Each MDMA-assisted therapy session will be followed by three non-drug integrative therapy sessions.
