Abstract

This article describes the rationale and the specific methods for an open label pilot trial of 100 mg MDMA in combination with massed exposure therapy for PTSD, a treatment which involves daily exposure therapy sessions for two weeks which has found to be effective. We review the need for novel PTSD treatments and the existing research on MDMA-assisted therapy, and then describe the rationale for this novel treatment approach, including combining MDMA with a gold standard treatment, translational support for this treatment, strong dissemination potential, and strengths of providing massed exposure treatment. The specific methods of the open label pilot study are presented, followed by conclusions and future directions for this research. This study will enroll at least 15 adults with PTSD over the next 2 years in order to identify feasibility and lead to a manual describing how to combine MDMA with exposure therapy, tested in a randomized, placebo-controlled trial, with significant promise for dissemination and improving our ability to treat PTSD. ClinicalTrials.gov identifier: NCT05746572.
