This open-label, randomized study will assess the comparative effectiveness of two versus three active MDMA-assisted therapy sessions in U.S. military veterans with at least moderate chronic PTSD treated in an outpatient VA treatment clinic. The study will be conducted in up to 60 participants. Prior to the randomized portion of the study, each therapist pair team will treat one participant under the 3-session model, and one participant under the 2-session model. In total, 8 participants will be treated under this proof of principle therapist training lead-in. A 120 mg dose of MDMA, followed by a supplemental dose (60 mg) unless contraindicated, is administered during the treatment period with manualized psychotherapy in 2 or 3 open-label monthly Experimental Sessions. This ~ 8-12-week Treatment Period includes three Preparatory Sessions prior to the first MDMA-assisted session. During the treatment period, each Experimental Session is followed by three Integrative Sessions of non-drug therapy. The Primary Outcome measure, the change in CAPS-5 from Baseline, is assessed by a centralized, blinded Independent Rater (IR) pool at post-treatment for each group.
