MAPS has announced that the second part of its Phase 3 trial of MDMA-assisted therapy for PTSD has confirmed prior positive trial results.

The first part of the Phase 3 trials had potentially historically significant results, and the entire industry has been waiting for the second part of its Phase 3 study. A successful outcome in this confirmatory Phase 3 trial would set the stage for a likely FDA approval of MDMA for PTSD.

Today’s news was a teaser with few details. But the fact that MAPS went public announcing positive results means we can feel pretty confident that the trial produced successful patient outcomes. Some highlights:

• MAPP2, the second Phase 3 trial of MDMA-assisted therapy, treated 104 participants living with PTSD with either MDMA-assisted therapy or placebo with therapy
• The results confirmed findings from MAPP1; no serious adverse events were observed among the participants

The full data from MAPP2 is expected to be published in a peer-reviewed journal later this year and will support MAPS PBC’s new drug application to be filed with the U.S. Food and Drug Administration (FDA).

Prior Positive Results Confirmed in MAPS-Sponsored, Philanthropy-Funded Phase 3 Trial

• MAPP2, the second Phase 3 trial of MDMA-assisted therapy, treated 104 participants living with PTSD with either MDMA-assisted therapy or placebo with therapy
• The results confirmed findings from MAPP1; no serious adverse events were observed among the participants
• In a first for psychedelic-assisted therapy trials, more than half of MAPP2 participants identify as people of color

The nonprofit Multidisciplinary Association for Psychedelic Studies’ (MAPS) clinical research program has achieved an important milestone: a successful confirmatory Phase 3 trial of MDMA-assisted therapy for posttraumatic stress disorder (PTSD). The clinical research program that began in 1992 has been sponsored by the nonprofit MAPS and funded through philanthropic donations. Since 2014, MAPS Public Benefit Corporation (MAPS PBC), a wholly-owned subsidiary of MAPS, has administered the trials.

When I first articulated a plan to legitimize a psychedelic-assisted therapy through FDA approval, many people said it was impossible. Thirty-seven years later, we are on the precipice of bringing a novel therapy to the millions of Americans living with PTSD who haven’t found relief through current treatments. The impossible became possible through the bravery of clinical trial participants, the compassion of mental health practitioners, and the generosity of thousands of donors. Today, we can imagine that MDMA-assisted therapy for PTSD may soon be available and accessible to all who could benefit. – Rick Doblin, Ph.D.

The full data from MAPP2, expected to be published in a peer-reviewed journal later this year, will support MAPS PBC’s new drug application to be filed with the U.S. Food and Drug Administration (FDA).

By 1985, MDMA had been legally used in therapy treatments for a decade, with a growing body of promising anecdotal reports supporting its use. However, increasing social use led the Drug Enforcement Agency to criminalize the use and possession of MDMA that year. In 1986, Dr. Doblin founded MAPS to fund and facilitate research into the potential of psychedelic-assisted therapies; educate the public about psychedelics for medical, social, and spiritual use; and advocate for drug policy reform. A major milestone was reached in 2021 when Nature Medicine published the positive results of the first Phase 3 trial, MAPP1, MAPP1 and MAPP2, the only completed Phase 3 trials of a psychedelic-assisted therapy, were conducted at 15 sites in the US, Canada, and Isreal. Today, Phase 2 trials are being planned or conducted evaluating MDMA-assisted therapies for conditions closely related to PTSD, such as substance use disorder and eating disorders. Trials of other therapies in combination with MDMA are being planned or conducted, such as couples therapy and group therapy among Veterans. These additional Phase 2 trials will determine if MDMA-assisted therapies may be effective for other conditions or with other treatment modalities commonly used to address PTSD.

NOTE

The safety and efficacy of psychedelic-assisted therapies are currently under investigation. No psychedelic-assisted therapy has been approved by the FDA or other regulatory authorities; no therapy works for everyone; and all therapies, even in clinical settings, carry risks.
