A phase 3 clinical trial tested MDMA-assisted therapy against placebo for severe PTSD. Participants received manualized therapy with either MDMA or placebo alongside preparatory and integrative sessions. At two months after the last session, the MDMA group showed a significantly greater reduction in PTSD symptoms (average 24.4-point drop on the CAPS-5 scale) compared to the placebo group (13.9-point drop), with a large effect size. Functional impairment also improved more with MDMA. No serious safety issues such as abuse potential, suicidality, or heart rhythm problems were observed. The findings suggest MDMA-assisted therapy is highly effective and safe for severe PTSD, including in people with common co-occurring conditions.

MDMA-assisted psychotherapy reduces posttraumatic stress disorder symptoms more than a low dose, with effects lasting at least 12 months. In a double-blind trial, 28 people with chronic PTSD received either 100 mg, 125 mg, or 40 mg of MDMA during psychotherapy sessions. The active dose groups showed larger reductions in Clinician-Administered PTSD Scale scores one month after two sessions, with mean changes of -26.3 for 125 mg, -24.4 for 100 mg, and -11.5 for 40 mg. At 12-month follow-up, 76% no longer met PTSD criteria. No serious adverse events occurred, and the treatment was well-tolerated.

A phase 3 clinical trial tested MDMA-assisted therapy for severe PTSD. In 90 participants randomized to receive either MDMA or placebo alongside therapy, those receiving MDMA showed a significantly larger reduction in PTSD symptoms, with an average decrease of 24.4 points on the CAPS-5 scale compared to 13.9 points in the placebo group. Functional impairment also improved more with MDMA. No serious safety issues like abuse potential or suicidality were observed. The treatment was effective even for patients with common co-occurring conditions such as depression or substance use history. The authors conclude MDMA-assisted therapy is a safe and highly effective treatment for severe PTSD.

In Brazil's first clinical trial of MDMA-assisted psychotherapy for post-traumatic stress disorder (PTSD), three patients with PTSD from sexual abuse completed treatment. The protocol involved 15 weekly therapy sessions, with three sessions including orally administered MDMA combined with psychotherapy and music, spaced about a month apart. Two months after the final MDMA session, all three patients showed clinically significant improvement, with CAPS-4 scores dropping by more than 30% from baseline. Final scores were 61, 27, and 8, down from 90, 78, and 72. No serious adverse events occurred; common side effects were somatic pains and anguish. Secondary outcomes also improved. MDMA-assisted psychotherapy could become a viable PTSD treatment in Brazil.

A conceptual framework for MDMA-Assisted Therapy for PTSD centers on the participant's inner healing intelligence as the primary agent of change, with the therapeutic relationship as the core facilitative condition. This inner-directed, holistic, self-directed, relational, and trauma-informed approach includes a non-pathologizing stance toward embodied experiences, such as intense emotional expression, multiplicity, suicidal ideation, and transpersonal experiences. Therapists bring psychodynamic, somatic, and transpersonal awareness, empathic attunement, relational skillfulness, and cultural humility. MDMA with this psychotherapy outperformed placebo with psychotherapy in Phase 2 and 3 trials, though significant symptom reduction also occurred in the placebo group, supporting the psychotherapy model itself.
