| Posttraumatic Stress Disorder | Drug: 3,4-methylenedioxymethamphetamine Drug: Lactose placebo pill Behavioral: Therapy | Phase 2 |
Posttraumatic stress disorder (PTSD) occurs in response to a traumatic event or events. It is most likely to occur following an event involving perceived personal threat, such as rape or physical assault. PTSD is clearly a public health problem that causes a great deal of suffering and accounts for a significant portion of health care costs.
MDMA is a substance possessing unique effects that make it well suited to intensive psychotherapy. MDMA has been hypothesized to represent a new class of drugs, called entactogens, that produce feelings of closeness to others, empathy, well being, and insightfulness. Anecdotal reports of therapy conducted before MDMA was placed on Schedule I suggest that MDMA-assisted psychotherapy may benefit people with PTSD.
This randomized, double-blind placebo-controlled study assessed the safety and effectiveness of MDMA-assisted therapy among people with chronic, treatment-resistant PTSD, including veterans. The study enrolled 23 participants. Participants were assigned to receive either therapy with a single divided dose of MDMA or lactose placebo during two blinded experimental sessions spaced three to five weeks apart during Stage 1 of the study. During these experimental sessions, participants received an initial dose of 125 mg of MDMA followed by a supplemental dose of 62.5 mg of MDMA, or they received initial and supplemental doses of inactive placebo. Psychotherapists and independent raters were blinded to participants' treatment conditions. This treatment period also consisted of preparatory sessions and several non-drug therapy sessions to facilitate integration of material arising during experimental sessions.
During Stage 2 of the study, the blind was broken and participants assigned to receive MDMA in Stage 1 underwent a third open-label experimental session of MDMA-assisted therapy. Participants assigned placebo during Stage 1 who chose to enroll in Stage 2 underwent three open-label sessions of MDMA-assisted therapy. Outcome measures were administered two months after the second MDMA or placebo session in Stage 1 and four to six weeks after the second MDMA session in Stage 2. A final data-collection session took place at two months after the third experimental session.
The primary objective of the study was to measure change in PTSD symptoms via CAPS-IV across the study in participants receiving the placebo vs. full dose of MDMA-assisted psychotherapy.

- Baseline Clinician-Administered PTSD Scale for DSM-IV (CAPS-IV) [ Time Frame: Less than 4 weeks before first experimental session ]The CAPS-IV is a structured clinical interview designed to assess the symptoms and severity of PTSD. The CAPS-IV provides a means to evaluate the frequency and intensity dimensions of each symptom, the impact of symptoms on the patient's social and occupational functioning, the overall severity of the symptom complex, global improvement since baseline, and the validity of the ratings obtained. Total severity scores range from 0 to 136, with higher scores indicating greater severity of PTSD symptoms.
- Primary Endpoint Clinician-Administered PTSD Scale for DSM-IV (CAPS-IV) [ Time Frame: 2 months after second experimental session ]The CAPS-IV is a structured clinical interview designed to assess the symptoms and severity of PTSD. The CAPS-IV provides a means to evaluate the frequency and intensity dimensions of each symptom, the impact of symptoms on the patient's social and occupational functioning, the overall severity of the symptom complex, global improvement since baseline, and the validity of the ratings obtained. Total severity scores range from 0 to 136, with higher scores indicating greater severity of PTSD symptoms.
- Change in Clinician-Administered PTSD Scale (CAPS-IV) From Baseline to 2-month Follow-up [ Time Frame: Baseline to 2 months post second experimental session ]The Clinician-Administered PTSD Scale for DSM-IV (CAPS-IV) is a clinician administered and scored assessment of PTSD symptoms via structured interview based upon PTSD diagnosis in DSM-IV. 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 Impact of Events Scale Revised (IES-R) [ Time Frame: Baseline (less than 4 weeks before first experimental session) ]The Impact of Events Scale Revised (IES-R) is a 22-item self-report measure (for DSM-IV) designed to measure the extent to which a given stressful life event produces subjective distress. Each item corresponds directly to 14 of the 17 DSM-IV symptoms of PTSD and is rated on a 5-point scale ranging from 0 ("not at all") to 4 ("extremely") for the extent to which the item was true for the participant during the past seven days. The IES-R yields a total score ranging from 0 to 88 with higher scores indicated greater distress.
