Detailed Description
PTSD is a stress-related psychiatric condition that may occur following a traumatic event such as war, disaster, sexual abuse, violence, terrorism, and accidents. PTSD negatively impacts 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 is a drug that releases serotonin, norepinephrine and dopamine in the brain and indirectly increases levels of the neurohormones oxytocin, arginine vasopressin and cortisol. The combined neurobiological effects of MDMA increase compassion, reduce defenses and fear of emotional injury, and enhance communication and introspection. MDMA produces anxiolytic and prosocial effects, which counteract avoidance and hyperarousal in the context of therapy. A combined treatment of MDMA and psychotherapy may be especially useful for treating PTSD.
This multi-site, open-label, Phase 2, lead-in study assesses the safety and effect of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy in participants diagnosed with at least severe posttraumatic stress disorder (PTSD). Therapy teams that have been identified and trained to work on the sponsor's planned Phase 3 studies will treat at least one open-label participant in this study. A flexible dose of MDMA (100 to 125 mg), followed by a supplemental half-dose, unless contraindicated, is administered during the Treatment Period with manualized therapy in three open-label 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. The primary outcome measure is the change in the Clinician Administered PTSD Scale for DSM 5 (CAPS-5) total severity scores from Baseline to Visit 19. The secondary outcome measure is the change in the customized version of the Sheehan Disability Scale (SDS) for PTSD for the MAPS studies total scores from Baseline to Visit 19.

---|---|---|
Change From Baseline to Primary Endpoint in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Total Severity Score
Time Frame: Baseline (Visit 3) to Primary Endpoint (Visit 19,18 weeks post enrollment)
|
The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) is a clinician administered and scored assessment of PTSD symptoms via structured interview based upon PTSD diagnosis in DSM-5.
It contains symptom subscales, a CAPS-5 total severity score, and a diagnostic score.
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.

The Sheehan Disability Scale (SDS for PTSD for MAPS) is a self-report assessment of functional impairment.
The reporting period for the adapted SDS refers to the past month.
The items indicate degree of impairment in the domains of work/school, social life, and home life, with response options based on an eleven-point scale (0=not at all to 10=extremely), with higher scores indicating greater functional impairment.
