mdma-assisted psychotherapy for anxiety associated with a life-threatening illness

Conditions: Anxiety

Summary: the goal of this clinical trial is to learn if mdma-assisted therapy is safe and effective in people with anxiety associated with a life-threatening illness. the main question it aims to answer is: does anxiety decrease in people receiving two sessions of mdma-assisted therapy? researchers will compare people receiving placebo with therapy to people receiving mdma-assisted therapy. * participants will undergo three non-drug preparatory therapy sessions before their first blinded session of mdma or placebo with therapy. * each medication session will be followed by three non-drug integrative therapy sessions. * after the second blinded medication session, participants receiving mdma will complete a third open-label medication session. * participants who received placebo will be given the option to crossover and receive three sessions of assisted therapy.

this phase 2 pilot study is a randomized, double-blind, placebo-controlled study in 18 participants comparing the effects of mdma-assisted therapy vs. placebo with therapy. thirteen participants were randomized to the active dose condition of 125 mg of mdma hcl (plus an optional supplemental dose of 62.5 mg mdma hcl) with therapy and five participants were randomized to the placebo with therapy condition. the study consisted of two blinded experimental sessions of mdma-assisted therapy or placebo with therapy, each session lasting six to eight hours and scheduled two to four weeks apart. each participant was unblinded one month after their second experimental session in stage 1. after unblinding, participants receiving mdma were to complete a third open-label experimental session of mdma-assisted therapy and participants who originally received placebo had the opportunity to cross over to open-label stage 2 and receive active mdma-assisted therapy in 3 sessions. the primary objective of the study is to assess changes in trait anxiety in subjects receiving active dose mdma compared to those receiving placebo as measured by state-trait anxiety index (stai) trait scores from baseline to the primary endpoint (one month after the second experimental session).
