MAPS will conduct a Phase 2, open-label, multi-site study for MDMA as an adjunct to psychotherapy for anorexia nervosa restricting subtype (AN-R) and binge eating disorder (BED). This study will explore the safety and feasibility of MDMA-assisted psychotherapy and adjunctive caregiver involvement in the treatment of individuals with AN-R and BED. The addition of a supportive caregiver as a treatment ally with every participant reflects this most recent development in science and practice. Supportive caregivers enrolled in the study will receive non-drug psychotherapy support. The study will enroll 12 participants who meet the Diagnostic Statistical Manual for Mental Disorders Edition 5 (DSM-5) criteria for Anorexia Nervosa (AN-R), and 6 participants who meet DSM-5 criteria for BED, for a total of 36 participants (12 AN-R, 6 BED, and 18 caregivers).
The study will take place at three study sites. The study site in Vancouver, Canada, will include six Binge Eating Disorder (BED) participants, with Qualified Investigator Christian Schütz overseeing the study. The study sites in Toronto, Canada, and Denver, Colorado, will each include six Anorexia Nervosa (AN-R) participants, with Michael Verbora overseeing as Qualified Investigator in Toronto, and co-Clinical Investigators Adele Lafrance and Mike Rollin overseeing the site in Denver.
