Clinical Trial Summary

This multi-site double-blind, placebo-controlled randomized Phase 3 study assesses the efficacy and safety of MDMA-assisted therapy versus placebo with therapy in participants diagnosed with at least severe PTSD. The study will be conducted in up to N ≈ 100 participants. Participants will be randomized to receive a flexible dose of MDMA or placebo, followed by a supplemental half-dose, unless contraindicated, during the Treatment Period with manualized therapy in three monthly Experimental Sessions. This ~12-week Treatment Period is preceded by three Preparatory Sessions. During the Treatment Period, each Experimental Session is followed by three Integrative Sessions of non-drug psychotherapy.

Description:

Posttraumatic stress disorder (PTSD) is a stress-related psychiatric condition that may occur following a traumatic event such as war, disaster, sexual abuse, violence, terrorism, or accidents. PTSD can negatively impact a person's daily life, resulting in relationship difficulties, difficulty in finding and maintaining a job, reduced cognitive and psychosocial functioning, substance abuse, high-cost healthcare use, and increased depression and suicide risk. Available PTSD treatments, including medications and therapy, effectively treat only a fraction of people who try them for adequate dose and duration. People with PTSD can be treated with psychotherapies and pharmacotherapies. In the past decade, there has been a growing amount of research into medications and other methods that may augment the effectiveness of psychotherapy for PTSD.

3,4-methylenedioxymethamphetamine (MDMA) induces serotonin release and has been shown to enhance fear memory extinction, modulate fear memory reconsolidation, and bolster social behavior in animal models. Pooled analysis of six Phase 2 trials of MDMA-assisted therapy for PTSD have now shown promising safety and efficacy findings.

This multi-site, double-blind, randomized Phase 3 study assessed the efficacy and safety of MDMA-assisted therapy versus placebo with therapy in participants diagnosed with at least severe PTSD. The study will be conducted in N ≈ 100 participants. Participants will be enrolled in one of two groups at a 1:1 ratio. A flexible dose of MDMA or placebo, followed by a supplemental half-dose unless contraindicated, is administered during the Treatment Period with manualized therapy in three monthly Experimental Sessions. This ~12-week Treatment Period is preceded by three Preparatory Sessions. During the Treatment Period, each Experimental Session is followed by three Integrative Sessions of non-drug psychotherapy. Initial doses per Experimental Session include 80 mg or 120 mg of MDMA or placebo followed 1.5 to 2 hours later by a supplemental half-dose (40 or 60 mg). Total amounts of MDMA to be administered per Experimental Session range from 80 mg to 180 mg.

The Primary Outcome measure is change in Clinician Administered PTSD Scale for DSM-V (CAPS-5) from Baseline to Primary Endpoint (18 weeks post-Baseline). Drug safety will be assessed by measuring blood pressure, heart rate and body temperature during experimental sessions, collecting adverse events and measuring suicidal thoughts or behaviors with the Columbia Suicide Severity Rating Scale (adapted C-SSRS).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline to Primary Endpoint in Clinician Administered PTSD Scale for DSM-V (CAPS-5)	The Clinician-Administered PTSD Scale for DSM-V (CAPS-5) is a clinician administered and scored assessment of PTSD symptoms via structured interview based upon PTSD diagnosis in DSM-5. The total severity score is a sum of symptom frequency and intensity scores for the subscales B (re-experiencing), C (avoidance) and D (hypervigilance) and ranges from 0 to 136, with higher scores indicating greater severity of PTSD symptoms.	Baseline to 18 weeks post enrollment confirmation
Secondary	Change From Baseline to Primary Endpoint in Sheehan Disability Scale (SDS) Total Score	The Sheehan Disability Scale (SDS) is a clinician-rated assessment of functional impairment that was adapted for the purposes of this study to limit missing item-level data as per the FDA requirements and included use of the three-item mean as the total score and imputation of work-related impairment. The SDS is a 3-item scale measuring the severity of disability in the domains of work, family life/home responsibilities and social/leisure activities, with each item scored on a ten-point Likert scale from 0 ('not at all impaired') to 10 ('very severely impaired'). The SDS total score was the mean of the 3 item responses. The SDS total score ranged from 0 to 10, with higher scores indicating greater functional impairment.	Baseline to 18 weeks post enrollment confirmation
