Brief Summary:
The goal of this clinical trial is to compare full dose MDMA-assisted therapy to placebo with therapy in participants with chronic, treatment-resistant PTSD. The main question it aims to answer is: Does MDMA-assisted therapy versus placebo with therapy reduce PTSD symptoms?
Participants will receive either MDMA-assisted therapy or placebo with therapy during two blinded experimental sessions spaced three to five weeks apart. During experimental sessions, participants receive an initial dose of 125 mg of MDMA HCl, or placebo, followed by a dose of 62.5 mg of MDMA HCl, or placebo. During this treatment period, participants will also undergo non-drug preparatory therapy sessions and non-drug integration sessions.
Researchers will compare PTSD symptoms in the MDMA-assisted therapy group to the placebo with therapy group to see if there is a reduction in symptoms after the treatment period. Safety measures will also be assessed between groups.

Detailed Description:
This randomized, double-blind, placebo-controlled clinical study will assess the safety and efficacy of MDMA-assisted therapy in treating chronic, treatment-resistant PTSD. In Stage 1, participants will be randomized to either MDMA-assisted therapy or placebo with therapy during two blinded experimental sessions, spaced three to five weeks apart. During experimental sessions, participants receive an initial dose of 125 mg of MDMA HCl, or placebo, followed by a dose of 62.5 mg of MDMA HCl, or placebo. During this treatment period, participants will also undergo non-drug preparatory therapy sessions and non-drug integration sessions. After this treatment period, participants will complete the primary endpoint assessment and the study will become unblinded.
Participants who were assigned to receive MDMA-assisted therapy will receive a third session of MDMA-assisted therapy that is open-label and participants assigned to receive placebo with therapy will have the option to enter Stage 2. Stage 2 will explore the optimal therapeutic dose of MDMA in a clinical titration dosing strategy. Participants will receive MDMA-assisted with an initial dose of 100 mg followed by a dose of 50 mg of MDMA HCl for the first experimental session. In the second and third experimental sessions, participants will have the option to increase the dose to an initial dose of 125 mg followed by a dose of 62.5 mg.
A blinded independent rater will assess PTSD symptoms via the CAPS-IV as well as other secondary outcome measures and safety measures.
