Trial Overview

Purpose of the Study

This multi-center study is designed to provide information on whether the drug MDMA combined with psychotherapy is safe and helpful for people with PTSD. Each volunteer will be assigned at random (like flipping a coin) to get either MDMA with psychotherapy or psychotherapy with a placebo. Volunteers will have a 50/50 chance of being assigned to either group.

To ensure every study volunteer is safely evaluated in the trial, the study staff will meet with them to ask questions about their medical and psychiatric history. This is called screening. Potential volunteers will need to provide medical records, have blood drawn, and visit with a study cardiologist. If the volunteer is eligible for the study, they will meet with the study therapists for psychotherapy 15 times over about 4-5 months. There will be three day-long therapy sessions (with MDMA or placebo) and 12 other therapy sessions that are 1.5 hours long. Throughout the study, volunteers will complete questionnaires about how they are doing and meet throughout the study with qualified researchers over telemedicine (video) who will ask questions about their symptoms. At the end of the study, the study therapists and volunteer will meet one final time.

Phase of Research

Phase 3

MDMA-assisted psychotherapy for PTSD is currently in Phase 3 clinical trials in the US, Canada, and Israel. This means that previous studies have been completed that suggested MDMA-assisted psychotherapy is safe and effective for treating PTSD. The Phase 3 clinical trials will enroll more participants to determine if the previous study results were correct and collect more data on the risks and benefits of the drug.
