After years of lobbying and experimental research, the FDA has granted breakthrough therapy" status for the drug MDMA as a potential treatment for post-traumatic stress disorder. The designation does not mean the drug is FDA-approved, but it does ease the way for clinical trials to test its safety and effectiveness in patients with PTSD. The non-profit Multidisciplinary Association for Psychedelic Studies (MAPS), which has been advocating and fundraising for MDMA research for three decades, announced the FDA's designation. More commonly known as its street names ecstasy or Molly, MDMA (methylenedioxymethamphetamine) is a psychoactive drug that produces feelings of energy and euphoria, often followed by an emotional crash. In recent years, some in the scientific community have suggested it could have medical benefits, as well. In previous phases of clinical trials, the drug was shown to offer significant relief to sufferers of PTSD, a mental health disorder characterized by nightmares or flashbacks and heightened anxiety or depression after experiencing or witnessing a terrifying event. In phase 2 clinical trials sponsored by MAPS, 61 percent of the 107 participants with chronic, treatment-resistant PTSD no longer had the disorder after two months of MDMA-assisted psychotherapy treatment. At a 12-month follow up, 68 percent no longer had PTSD. The organization expects to begin phase 3 trials with a larger group of participants next year.
