A Randomized, Double-Blind, Dose Response Phase 2 Pilot Study of Manualized MDMA-Assisted Psychotherapy in Subjects With Chronic, Treatment-Resistant Posttraumatic Stress Disorder (PTSD)

Resilient Pharmaceuticals·interventional·Posted Feb 15, 2013·Updated Jun 5, 2025

In Brief

A Phase 2 clinical trial evaluating Comparator Dose (40mg) MDMA HCl, Active Dose 2 (100 mg) MDMA HCl, and 2 other interventions for Posttraumatic Stress Disorder. Completed, enrolled 29 participants across 1 site.

Detailed Summary

The goal of this clinical trial is to learn if MDMA in combination with therapy is safe and effective in people with chronic, treatment-resistant PTSD. The main questions it aims to answer are: * Does MDMA-assisted therapy reduce PTSD symptoms? * Is there a difference in PTSD symptoms between the 40 mg, 100 mg, and 125 mg groups? Researchers will compare two active doses (100 mg and 125 mg) of MDMA-assisted therapy versus a comparator dose of 40 mg MDMA-assisted therapy to determine if there is a reduction in PTSD symptoms. Participants will undergo three non-drug preparatory sessions, three MDMA-assisted therapy sessions and three non-drug integrative therapy sessions after each MDMA-assisted therapy session.

Active Dose 2 (100 mg) MDMA HCldrug

An initial dose of full-dose 100 mg midomafetamine HCl orally given at the start of two separate psychotherapy sessions scheduled 3 to 5 weeks apart, with the initial dose possibly followed 1.5 to 2.5 hours later by a supplemental dose half the size of the initial dose (50 mg).

Active Dose 1 (125 mg) MDMA HCldrug

An initial dose of full-dose 125 mg midomafetamine HCl orally given at the start of two separate psychotherapy sessions scheduled 3 to 5 weeks apart, with the initial dose possibly followed 1.5 to 2.5 hours later by a supplemental dose half the size of the initial dose (62.5 mg).
