On August 23, 2016, the first pair of participants received their second experimental treatment in our new study of MDMA combined with Cognitive Behavioral Conjoint Therapy (CBCT) for PTSD in Charleston, South Carolina. Final outcome measures for this pair (dyad) will be collected during the one-month follow-up taking place on October 9, 2016. The study will enroll 10 dyads, with one participant diagnosed with PTSD and one concerned significant other who does not have PTSD but does experience psychosocial distress. The primary goal of this study is to develop a combined method of MDMA with CBCT for PTSD. MDMA will be administered to both participants to help facilitate communication and connection between participants and therapists. We are currently screening additional local participants for this study.
