On April 16, 2012, Dr. Michael Mithoefer, the lead investigator for our recently completed long-term follow-up of subjects who participated in the initial U.S. proof of principle study, submitted a revised version of the paper in response to comments from reviewers. We’re hopeful the paper will soon be accepted for publication. The long-term follow-up, conducted an average of 3½ years after the last MDMA-assisted psychotherapy session, found that the benefits persisted over time, though a few subjects had relapsed due to new life stressors.
