MDMA/PTSD Switzerland Study (Completed)

MDMA-Assisted Psychotherapy in the Treatment of Posttraumatic Stress Disorder (PTSD)
Principal Investigator: Peter Oehen, MD, with co-therapist Verena Widmer, RN

Location: Solothurn, Switzerland

All data gathering has been completed and the results are being written up for publication. All 12 subjects with treatment-resistant PTSD have undergone the experimental treatment. The final subject's last visit took place on January 8, 2010. The final analysis was completed in January 2011, after the last measurements for the one-year, long-term follow-up phase of the study were collected from the final subject. The results will be published February 2013 in the Journal of Psychopharmacology.

Our Swiss MDMA/PTSD pilot study had full approval from an Ethics Committee (Swiss IRB equivalent) and SwissMedic (FDA equivalent). The protocol had also been submitted to, and accepted by, the FDA under MAPS’ Investigational New Drug (IND) application for MDMA. The study is a part of MAPS’ clinical plan to develop MDMA into a prescription medicine approved by both the FDA and the European Medicines’ Agency (EMEA).
