MDMA-assisted therapy for moderate to severe PTSD: a randomized, placebo-controlled phase 3 trial

Results from the phase 3 placebo-controlled MAPP2 trial show that MDMA-assisted therapy reduces post-traumatic stress disorder (PTSD) symptoms and functional impairment in a diverse population with moderate to severe PTSD.

Due to disparities in trauma exposure, gender-diverse and transgender individuals, ethnoracial minorities, first responders, military personnel, veterans and victims of chronic sexual abuse have a disproportionately higher risk of developing PTSD.

Mounting evidence supports substituted phenethylamine 3,4-methylenedioxymethamphetamine-assisted therapy (MDMA-AT) as a treatment for PTSD. MDMA, an entactogen that promotes monoamine reuptake inhibition and release (primarily by inducing conformational change of pre-synaptic transporters), effectively modulates fear memory reconsolidation, enhances fear extinction and promotes openness and prosocial behavior.
