Social Anxiety MDMA-Assisted Therapy Investigation

Two 8-hour experimental sessions will occur within the 11-session intervention in which participants will take a dose of MDMA. In the first Experimental Session, the initial dose will be 80 mg MDMA, with a supplemental dose of 40 mg 1.5 to 2 hours later unless contraindicated. In the second Experimental Session, the initial dose may be increased to 120 mg MDMA unless contraindicated with an additional dose of 40 mg 1.5 to 2 hours after the initial dose is given unless contraindicated.

Adjunctive, manualized psychotherapy will be provided by a team of two therapists during the MDMA-assisted therapy sessions
