The goal of this clinical trial is to learn if MDMA-assisted group therapy is safe and effective in in people with at least moderate PTSD.

The main question it aims to answer is: Do two sessions of open-label MDMA-assisted group therapy reduce PTSD symptoms?

Participants will undergo non-drug preparatory therapy sessions before their MDMA-assisted therapy sessions. After, they will undergo non-drug integrative therapy sessions.

To further assess the feasibility and safety of MDMA-assisted group therapy for participants with at least moderate PTSD, the sponsor is conducting a Phase 2, open-label, non-randomized, 3-cohort study. This novel treatment package consists of two once-monthly Experimental Sessions of therapy combined with a divided-dose of MDMA (120 mg midomafetamine HCl and optional supplemental dose of 60 mg 1.5 to 2 hours later), along with non-drug preparatory and integrative therapy administered in both individual and group sessions.

The Primary Outcome measure, the Clinician Administered PTSD Scale (CAPS-5), evaluates changes in PTSD symptom severity and is assessed by a blinded centralized Independent Rater (IR) pool. The therapeutic approach will combine manualized MDMA-assisted therapy for PTSD with group therapy components.
