The U.S. Food and Drug Administration (FDA) has denied the approval of MDMA, also known as ecstasy or molly, as a treatment for post-traumatic stress disorder (PTSD), citing limitations in the data presented by the drug's manufacturer, Lykos Therapeutics.
The FDA's announcement on Friday came as a disappointment to veteran organizations and mental health advocates who have long championed the use of psychedelic-assisted therapies, including MDMA, to address the debilitating effects of PTSD.
MDMA, a Schedule I controlled substance, has shown promise in clinical trials for treating PTSD, which affects an estimated 12 million adults in the United States. Studies have indicated that MDMA-assisted therapy can reduce symptoms and improve sleep and overall well-being in people with PTSD.

However, the FDA's decision was based on "significant limitations" in the data submitted by Lykos Therapeutics, the California company that filed the drug application. The agency noted that the clinical trials conducted did not fully meet the FDA's requirements for safety and efficacy.
"As discussed at the Advisory Committee meeting, there are significant limitations to the data contained in the application that prevent the agency from concluding that this drug is safe and effective for the proposed indication," an FDA spokesperson said in a statement.

The setback is particularly disappointing given the lack of new treatment options for PTSD in over two decades. Lykos Therapeutics CEO Amy Emerson expressed her dismay, stating, "The FDA request for another study is deeply disappointing, not just for all those who dedicated their lives to this pioneering effort, but principally for the millions of Americans with PTSD, along with their loved ones, who have not seen any new treatment options in over two decades."
Veteran organizations and mental health experts have long advocated for the approval of psychedelic-assisted therapies for PTSD. They argue that these therapies offer a unique opportunity to break through the limitations of traditional treatments and provide meaningful relief to those suffering from the disorder.

Despite the FDA's rejection, PharmAla Biotech, a company focused on MDMA research and development, expressed its commitment to continuing research and pursuing approval. "We believe that they are acting in good faith," said Nicholas Kadysh, CEO of PharmAla Biotech. "However, there is a vitally important patient need for novel PTSD treatments, which must be balanced with that prudency."
The FDA's decision underscores the complex and often challenging path to approval for new treatments, especially for those involving controlled substances. Nevertheless, the continued research and advocacy for psychedelic-assisted therapies provide hope for the millions of people living with PTSD that new options may be on the horizon.
