MDMA-Assisted Massed Exposure Therapy for PTSD

Description

Posttraumatic stress disorder (PTSD) affects many individuals, including military veterans and civilians exposed to trauma. While trauma-focused therapies like Prolonged Exposure (PE) are effective, many people do not fully recover, and current medications often have limited success.

This study will test whether combining PE therapy with a single dose of MDMA (a psychoactive drug) can improve PTSD treatment outcomes. Ninety-five participants with PTSD will be randomly assigned to receive either MDMA or a placebo during the second of ten PE therapy sessions, which are delivered over two weeks. Researchers will measure PTSD symptoms one month after treatment using a standardized interview.

The study will also explore how MDMA affects brain responses related to fear and emotional memory, which may help explain how it works. Early results from a pilot study suggest this combination may lead to large reductions in PTSD symptoms. This is the first clinical trial to formally test MDMA with PE therapy, and it may lead to new, more effective treatment options for PTSD.
