The Costs and Health Benefits of Expanded Access to MDMA-assisted Therapy for Chronic and Severe PTSD in the USA: A Modeling Study

This study (2022) uses a decision-analytic model to assess the cost and health benefits of expanded access to MDMA-assisted therapy (MDMA-AT) in the phase III clinical trials from MAPS. Expanding access to MDMA-AT to 25-75% of eligible patients was projected to avert 43,618-106,932 deaths and gain 3.3-8.2 million quality-adjusted life-years (QALYs).

Abstract

Background and objective: Intensive psychotherapy assisted with 3,4-methylenedioxymethamphetamine (MDMA-AT) was shown in Phase 3 clinical trials to substantially reduce post-traumatic stress disorder (PTSD) symptoms compared to psychotherapy with placebo. This study estimates potential costs, health benefits, and net savings of expanding access to MDMA-AT to eligible US patients with chronic and severe PTSD.

Methods: Using a decision-analytic model, we compared the costs, deaths averted, and quality-adjusted life-years (QALYs) gained of three, 10-year MDMA-AT coverage targets (25%, 50%, and 75%) compared to providing a standard of care to the same number of eligible patients with chronic and severe PTSD. We used a payer perspective and discounted costs (in US$) and QALYs to 2020. We conducted one-way, scenario, and probabilistic sensitivity analyses and calculated the net monetary value of MDMA-AT using a cost-effectiveness threshold of $100,000 per QALY gained.

Results: Expanding access to MDMA-AT to 25-75% of eligible patients is projected to avert 43,618-106,932 deaths and gain 3.3-8.2 million QALYs. All three treatment targets are dominant or cost-saving compared to the standard of care. Our sensitivity analyses found that accounting for parameter uncertainty and changes in various assumptions did not alter the main finding-MDMA-AT is dominant compared to standard of care.

Conclusion: Expanding access to MDMA-AT to patients with chronic and severe PTSD will provide substantial health and financial benefits. The precise magnitude is uncertain and will depend on the number of eligible patients and other inputs.”

MDMA-assisted therapy for severe PTSD: a randomized, double-blind, placebo-controlled phase 3 study
This double-blind, placebo-controlled study (n=90) finds that MDMA-assisted therapy (3x 80-120mg) is effective (d=.91, large effect size) in the treatment of PTSD. 67% of those in the MDMA-group no longer qualified for PTSD (vs 32% for the therapy-only group). This study is part of the Phase III trial to get MDMA approved by the FDA.

A Multi-Site Phase 3 Study of MDMA-Assisted Psychotherapy for PTSD (MAPP1)
Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder that can develop after a traumatic life experience that severely reduces the quality of life. This multi-site, double-blind, placebo-controlled, randomized Phase 3 study assessed the efficacy and safety of MDMA-assisted psychotherapy compared to psychotherapy with placebo in participants diagnosed with at least moderate PTSD.
