On October 14, 2011, MAPS’ clinical research team submitted the final clinical study report for our recently completed Phase 2 Swiss study of MDMA-assisted psychotherapy for people with chronic, treatment-resistant PTSD to SwissMedic, the Swiss equivalent of the U.S. FDA. SwissMedic confirmed that the report had been received on October 18. The report, authored by MAPS Lead Clinical Research Associate Berra Yazar-Klosinski, Ph.D., and MAPS Research and Information Specialist Ilsa Jerome, Ph.D., is required under International Council on Harmonization/Good Clinical Practice (ICH/GCP) and FDA regulations. The report contains information about the study protocol, information about the conduct of the study, and all study data in both raw and analyzed formats. The study team is now preparing the results for publication in a peer-reviewed academic journal.
A statistical analysis of the results reveals clinically significant decreases in scores on the Clinician-Administered PTSD Scale (CAPS), with an average reduction of 15.6 points. Due to the small number of subjects in this small pilot study, however, these decreases did not reach statistical significance. We did, however, observe trends toward statistical significance in both the CAPS and the Posttraumatic Diagnostic Scale (PDS), the two measures used to evaluate symptom severity in study subjects.
