Brief Summary: The goal of this clinical trial is to learn if MDMA-assisted therapy is safe and effective at reducing PTSD symptoms in people with PTSD who received placebo in a prior MDMA-assisted therapy study.

The main question it aims to answer is:

Do PTSD symptoms decrease in people who receive a flexible dose of MDMA (120 or 180 mg MDMA HCl) with therapy in three sessions?

Participants will undergo three preparatory therapy sessions without any study drug, then three MDMA-assisted therapy sessions with a flexible dose of 80 or 120 mg, followed by three integrative therapy sessions without study drug after each MDMA-assisted therapy session.
Detailed Description: This multi-site, open-label safety extension study assesses the efficacy and safety of MDMA-assisted psychotherapy versus psychotherapy in participants diagnosed with PTSD. The study will be conducted in N ≈ 100 participants. Participants who were randomized to the placebo arm in either of the two parent Phase 3 trials of MDMA-assisted psychotherapy and who meet all other entry criteria will be eligible and invited to participate in this study. In addition, participants in the parent Phase 3 trials who were unable to complete the study due to the COVID-19 pandemic or other unforeseen circumstances may participate in this study.

The treatment consists of an initial dose of midomafetamine HCl (80 or 120 mg), followed by a supplemental dose (40 or 60 mg) unless contraindicated, administered with manualized psychotherapy in three open-label Experimental Sessions each spaced approximately one month apart. During Experimental Session 1, participants will receive an initial dose of 80 mg of midomafetamine HCl, followed by a supplemental dose of 40 mg. During Experimental Sessions 2 and 3, participants will receive an initial dose of 80 or 120 mg of midomafetamine HCl, followed by a supplemental dose of 40 or 60 mg.

This Treatment Period is preceded by three Preparatory Sessions. During the Treatment Period, each Experimental Session is followed by three Integrative Sessions of non-drug psychotherapy. Experimental Sessions are followed by an overnight stay, with the exception of a subset of participants who will be invited to participate in a sub-study to assess the feasibility of Experimental Sessions without overnight stay. The primary study endpoint is the change from baseline in PCL-5 (PTSD Checklist for DSM-5) scores from Visit 3 to Visit 16.
