This study is designed to provide information on whether psychotherapy (“talk therapy”) combined with the drug MDMA is safe and helpful for subjects with posttraumatic stress disorder (PTSD).
The study will compare the effects of a low, a medium and a full dose of MDMA on symptoms of PTSD in 24 veterans, firefighters or police officers. MDMA dose will be assigned at random, and the investigators and the subject will not know the dose given. The researchers will also investigate depression symptoms.
The researchers believe that the full dose of MDMA will produce a greater reduction in PTSD symptoms than the two lower doses.

Discontinuation of medications classified as reuptake inhibitors affects treatment response of MDMA-assisted psychotherapyA pooled analysis of participants (n=50) in Phase II MDMA trials for PTSD found that recent tapering off SSRIs may reduce treatment response (CAPS-IV score).
3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for post-traumatic stress disorder in military veterans, firefighters, and police officers: a randomised, double-blind, dose-response, phase 2 clinical trial
This Phase II clinical trial (n=26) finds that MDMA-assisted psychotherapy (75-125 mg) led to significant and sustained decreases in PTSD (CAPS-IV) scores as compared to an active placebo (30 mg). At the 12-month follow-up, the average CAPS-IV score had dropped from 87 to 39 (67% no longer qualified for PTSD diagnosis).
MDMA-assisted psychotherapy for treatment of PTSD: study design and rationale for phase 3 trials based on pooled analysis of six phase 2 randomized controlled trials
This pooled analysis (n=105; s=6) of MAPS' Phase II trials finds significant improvements (Cohen's d=0.8) and no significant adverse effects with MDMA-assisted therapy for PTSD. This analysis has been done to support starting the Phase III trials (which have taken place).
Long-term Follow-Up Outcomes of MDMA-assisted Psychotherapy for Treatment of PTSD: A Longitudinal Pooled Analysis of Six Phase 2 Trials
This long-term follow-up study (n=107) examines the effects of MDMA-assisted psychotherapy on PTSD symptoms. It finds a significant reduction in PTSD symptoms both at treatment exit and at least 12 months post-treatment, with 67% of participants no longer meeting PTSD criteria at long-term follow-up.
