On January 20, 2012, the first of two subjects eligible for our relapse study of MDMA-assisted psychotherapy for PTSD was screened. This study will enroll two subjects whose PTSD symptoms eventually returned after participating in our U.S. flagship study of MDMA-assisted psychotherapy for PTSD, which was completed in July 2010. This is an open-label proof-of-principle study intended to test whether an additional MDMA-assisted psychotherapy session and several associated non-drug psychotherapy sessions can once again heal these subjects.
