At the request of our Institutional Review Board (IRB), MAPS has established a Data Safety Monitoring Board (DSMB) that works for MAPS reviewing the data from Dr. Mithoefer’s MDMA/PTSD study on an ongoing basis. The DSMB met today to review the charts from the first five subjects who have completed their final follow-up evaluation. which takes place two months after the second experimental session. The DSMB concluded that “We did not see any significant adverse events that caused us any concerns about the safety of this study.” They recommended that “the study continue without modification.” The next scheduled meeting of the DSMB will take place after the next five subjects (the 6th-10th) have completed their final follow-up evaluations. The DSMB will also meet if there is a serious adverse event.
