In a phase 3 trial, MDMA-assisted therapy reduced PTSD symptoms and functional impairment more than placebo with therapy in 104 participants with moderate to severe PTSD. The average decrease in PTSD symptom severity was 23.7 points with MDMA-assisted therapy versus 14.8 points with placebo, and functional disability improved by 3.3 versus 2.1 points. Participants were ethnoracially diverse, with 27% identifying as Hispanic/Latino and 34% as other than White. Severe side effects occurred in 9.4% of the MDMA group and 3.9% of the placebo group; no deaths or serious adverse events were reported. The treatment was generally well tolerated.
