Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if MDMA-assisted therapy is safe and effective and reducing PTSD symptoms in veterans with chronic PTSD. The main question it aims to answer is: Do three doses of MDMA reduce PTSD symptoms?

Researchers will compare 30, 75, and 125 mg of MDMA HCl with therapy to see which dose best reduces PTSD symptoms.

Participants will undergo three preparatory non-drug therapy sessions with a male and female co-therapist team, then undergo three day-long MDMA-assisted therapy sessions after receiving an initial dose of 30, 75, or 125 mg MDMA HCl. After each MDMA-assisted therapy session, participants will undergo three integrative therapy sessions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a randomized, double-blind, dose comparison study with an open-label cross-over segment that will assess the safety and efficacy of MDMA-assisted therapy in veterans with chronic PTSD. Twelve of 24 participants will receive the full dose of 125 mg, six will receive 75 mg and six will receive 30 mg (active placebo dose) of MDMA HCl. An independent rater blind to condition will assess symptoms of PTSD and depression, general quality of life and posttraumatic growth prior to any therapy sessions one month after the second experimental session.

After undergoing three 90-minute non-drug introductory therapy sessions with a male/female co-therapist team, study participants will undergo two eight-hour long experimental sessions scheduled three to five weeks apart, prior to which they will be randomized to receive an initial dose of 30, 75 or 125 mg MDMA HCl , followed by a supplemental dose of half the initial dose 1.5 to 2.5 hours later. Participants will undergo integrative therapy in between each experimental session, including on the day after each session. Vital signs and psychological distress will be measured throughout each experimental session, and suicidality will be assessed throughout the course of the study. Spontaneously reported side effects will be collected on the day of each experimental session, and for six days afterward. PTSD symptoms, symptoms of depression, general psychological function, posttraumatic growth and quality of sleep will be assessed one month after the second experimental session, and the blind will be broken.

Participants who received 125 mg MDMA HCl will continue to have a third experimental session, and they will be assessed two months after the third experimental session.

Participants who received 30 or 75 mg MDMA HCl may take part in an open-label crossover segment that will follow nearly identical procedures, except that there will only be one introductory session prior to the first experimental session. There will be three experimental sessions. Symptoms of PTSD, depression and posttraumatic growth will be assessed at the start of the study. They will also be assessed one month after the second and two months after the third experimental session.

All participants will be assessed 12 months after their final experimental session. PTSD and depression symptoms and posttraumatic growth will be assessed, and participants will complete a questionnaire concerning the costs and benefits of being in the study.
