This small (“pilot”) study is designed to provide information on whether the combination of psychotherapy with the drug MDMA is safe and helpful for people with post traumatic stress disorder (PTSD). The researchers will use the results of this study to design more studies of this treatment. The study compares a comparator (placebo) and a full dose.

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).
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.
Measures Used
Clinician-Administered PTSD Scale for DSM-5The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) is often considered the gold standard in PTSD assessment. The 30-item structured interview was developed by staff at the U.S. Department of Veterans Affairs National Centre for PTSD. CAPS can be used to make a current diagnosis, lifetime diagnosis or assess PTSD symptoms over the past week in accordance with DSM-5 criteria.
Beck Depression Inventory
The Beck Depression Inventory (BDI) contains 21 self-report items, completed using a multiple-choice format. Scores range from 0-63 with higher scores associated with more severe depression.
