Study Comparing Three Doses of MDMA Along With Therapy in Veterans With Posttraumatic Stress Disorder
Summary
The goal of this clinical trial is to learn if MDMA-assisted therapy is safe and effective and reducing PTSD symptoms in veterans with chronic PTSD. The main question it aims to answer is: Do three doses of MDMA reduce PTSD symptoms? Researchers will compare 30, 75, and 125 mg of MDMA HCl with therapy to see which dose best reduces PTSD symptoms. Participants will undergo three preparatory non-drug therapy sessions with a male and female co-therapist team, then undergo three day-long MDMA-assisted therapy sessions after receiving an initial dose of 30, 75, or 125 mg MDMA HCl. After each MDMA-assisted therapy session, participants will undergo three integrative therapy sessions.
