Research: MDMA-Assisted Therapy for PTSD

MAPS Completes Enrollment, as Planned, for the Confirmatory Phase 3 Trial of MDMA-Assisted Therapy for PTSD

  • The second, confirmatory Phase 3 trial of MDMA-assisted therapy for PTSD is now fully enrolled at 13 sites in the United States and Israel
  • Completion of enrollment on schedule supports targeted submission of the New Drug Application to the U.S. Food and Drug Administration (FDA) in the first half of 2023
  • Health Equity initiatives to enroll BIPOC and LGBTQIA+ participants improved representation of populations more likely to develop PTSD following exposure to trauma

The non-profit Multidisciplinary Association for Psychedelic Studies (MAPS) and MAPS Public Benefit Corporation (MAPS PBC), a wholly-owned subsidiary of MAPS, announced that a blinded administrative interim analysis has confirmed no changes to the planned sample size are necessary to provide sufficient statistical power in evaluating efficacy of MDMA-assisted therapy for posttraumatic stress disorder (PTSD) in the second of two Phase 3 trials (MAPP2). Per the special protocol agreement negotiated with the FDA for the confirmatory trial, MAPP2 was designed to enroll at least 100 participants in order to confirm efficacy and further investigate safety of the treatment. 

Phase 3 Trials of MDMA-Assisted Therapy for PTSD: Study Site Opens for Phone Screening in Tel Hashomer, Israel

On February 3, our Phase 3 study site for MDMA-assisted therapy for post-traumatic stress disorder (PTSD) in Tel Hashomer, Israel, officially opened for phone screenings and informed consent visits. Led by Principal Investigator Jana Yakirevitch, M.D., this is an FDA-regulated Phase 3 clinical trial of MDMA-assisted therapy for PTSD. 

All Study Sites Open in Phase 3 Cross-Over Extension Study

On March 22, 2022, all study sites met the criteria to provide treatment in the  cross-over extension study for MAPS-sponsored Phase 3 trials of MDMA-assisted therapy for posttraumatic stress disorder (PTSD).

All subjects who received placebo plus therapy in the double-blind portion of our first Phase 3 study of MDMA-assisted therapy for PTSD are given the opportunity to participate free-of-charge in a similarly designed study to receive MDMA plus therapy.

Long-Term Follow Up Study of MDMA-Assisted Therapy for PTSD

Enrollment is continuing for our long-term follow up study for our MDMA-assisted therapy parent studies. The long-term follow up study is open to individuals who participated and received MDMA in at least one experimental session in one of the following MAPS-sponsored MDMA-assisted therapy studies: open-label lead-in Phase 2 trials (U.S. and Canada), our two Phase 3 trials, or our Phase 3 cross-over trial.

Participation in this study will help us better understand the long-term effects of our treatment protocols. The long-term follow up study visits will be done remotely if the participant received treatment at a study site within the United States. If a participant had previously declined to participate in this follow-up study, it is not too late to enroll. Volunteers who received treatment in one of the aforementioned studies and wish to participate in this follow-up can reach out to their study coordinator for more information. Volunteers will receive $250 for participating in this study.

MAPS Places Fully Validated, Multi-Kilogram Synthesis of MDMA in the Public Domain

  • Multidisciplinary Association of Psychedelic Studies (MAPS) and MAPS Public Benefit Corporation (MAPS PBC) have developed the first validated commercial synthetic process for producing multi-kilogram batches of MDMA under current Good Manufacturing Practices (cGMP)
  • The availability of larger quantities of cGMP-compliant MDMA will facilitate ongoing clinical trials and provide for future therapeutic use following anticipated regulatory approvals
  • Publication of this process establishes “prior art,” contributing to MAPS’ patient access strategy by making intellectual property public 

MDMA is a promising psychedelic compound, currently placed by the Drug Enforcement Administration (DEA) in Schedule I of the Controlled Substances Act, that has been produced for legal research in small batches by certified laboratories. An increasing interest in clinical study of the 110-year-old compound, combined with anticipated regulatory approvals of MDMA-assisted therapy, necessitate the development of a multi-kilogram current cGMP production process by the leading research sponsor, MAPS, and trial organizer, MAPS PBC. “Fully Validated, Multi-Kilogram cGMP Synthesis of MDMA” recently published in ACS Omega, a journal of the American Chemical Society, is the first paper to describe a fully validated cGMP synthesis of up to 5 kg (≈30,000 patient doses) of MDMA in a four-step process beginning with a non-controlled starting material. 


Expanded Access is a program that allows patients to receive an investigational treatment not yet approved by the United States Food and Drug Administration (FDA) for treatment outside of a clinical trial. The program is intended for patients with serious or life-threatening conditions who do not have any promising treatment options and are unable to participate in ongoing clinical trials. Only sites within the U.S and U.S territories are eligible to participate in the FDA Expanded Access Program. 

The rationale for our Expanded Access program is not only to treat more patients with MDMA-assisted therapy, but also to understand logistics of how MDMA-assisted therapy will be administered post-approval by generating real world evidence (RWE).  Learn more:

In April 2022, we launched our first 100-hour blended (online/in person) training program and hosted a week-long in-person training retreat in North Carolina (pictured above). We welcomed over 75 trainees from all over the U.S. and a few international locations including Canada and Brazil. The training retreat included learning seminars, case video presentations, ethics and safety education, practice scenarios, and guest speakers. A dozen new employees, including MAPS PBC’s new COO, Mike Mullette, participated in this training as part of a recent onboarding process. 

In March 2022, the MDMA Therapy Training Program team kicked off the training season with a practice workshop with Naropa University and a week-long virtual training in collaboration with the Center for Psychedelic Psychotherapy and Trauma Research at Mount Sinai and the James J. Peters Department of Veterans Affairs.

Here are a few reflections that our recent trainees have shared about their MDMA Therapy Training experiences:  

“Thank you for the opportunity to be part of this training. Gives me hope for the future of mental health care for the Veteran community. Thank you all for putting it together.”  

“Best training I’ve ever had, honestly. Including outside of the VA.” 

“Thank you, Annie and Michael, for weathering so many storms bringing this treatment to the world and for never losing sight of what’s important.” 

“I am grateful I was able to participate in this first in-person retreat after the pandemic and am looking forward to more. Despite my newness to MDMA, I would love to become more involved.” 

“The training staff was amazing. They were attentive, kind, generous, organized, knowledgeable, responsive, present, and caring. This says a lot about the organization, its leadership, the kind of people it attracts, and how much effort, thought, and care goes into this retreat.” 

In 2021, the team rolled out and initiated our Health Equity Scholarship program, part of a larger commitment to increasing inclusion and equity in our programs. Over the course of this year, we were able to allocate and award $900,000 in Health Equity scholarships, amounting to a total of 231 scholarships. We are currently working to continue and expand this initiative for 2022 and beyond.

The training program enrolled 800 trainees in their 2021 online cohorts. 

By awarding funds through the MAPS Health Equity Scholarship, the MDMA Therapy Training Program hopes to continue the efforts to create these outcomes in 2022: 

  • Create a more accessible training program to ensure that the network of MDMA-Assisted Therapy Practitioners is vast and able to support diverse communities suffering from a spectrum of trauma. 
  • Increase the number of MAPS-Certified MDMA-Assisted Therapy Practitioners who identify as Black, Indigenous, and people of color. 
  • Train and learn from more therapy practitioners who live and work in historically marginalized communities. 
  • Foster connection and validate unique experiences of trauma in marginalized communities.
