On March 13, 2015, the 22nd subject received their first experimental treatment in our ongoing study of MDMA-assisted psychotherapy for 24 U.S. veterans, firefighters, and police officers with treatment-resistant PTSD. This subject was enrolled on February 10, and the 23rd subject was enrolled on March 2. The potential final subject is now being screened. Principal Investigator Michael Mithoefer, M.D., will be discussing preliminary results and ongoing research into MDMA-assisted psychotherapy for PTSD at the upcoming American Psychiatric Association Annual Meeting in Toronto, Canada, from May 16-20, 2015. MAPS will also host an educational booth in the exhibit hall. Learn more…
