On July 31, 2015, the final experimental session took place in our ongoing study of MDMA-assisted psychotherapy for 24 U.S. veterans, firefighters, and police officers with treatment-resistant PTSD. "We had our last experimental session today," reports Principal Investigator Michael Mithoefer, M.D. "It was, once again, a wonderful example of the power of MDMA-assisted therapy to bring healing, and to change the lives of people who have been suffering for years with PTSD." On July 13 and July 28, two additional subjects completed long-term follow-up interviews, which 17 out of 24 subjects have now completed. We expect that primary data analysis will be completed by October 2015, and that the last long-term follow-up interview will take place in August 2016. We anticipate that the results will be published in early 2016, after the data from this study and all of our other international Phase 2 pilot studies is submitted to the U.S. Food and Drug Administration for consideration of Breakthrough Therapy status.
