Change in Clinical Administered PTSD Scale (CAPS-IV) Total Score From Baseline to End of Stage 1 [ Time Frame: Baseline to 1-Month Post Experimental Session 2 (End of Stage 1) ]
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.

Descriptive Information
Brief Title  ICMJE Randomized, Double-blind, Active Placebo-Controlled Pilot Study of MDMA-assisted Psychotherapy in People With Chronic PTSD
Official Title  ICMJE A Randomized, Double-Blind, Active Placebo-Controlled Phase 2 Pilot Study of MDMA-assisted Psychotherapy in People With Chronic, Treatment-Resistant Posttraumatic Stress Disorder (PTSD)
Brief Summary This Phase 2 pilot study assessed the safety and efficacy of MDMA-assisted psychotherapy in 10 people with chronic, treatment-resistant posttraumatic stress disorder (PTSD), comparing the effects of low and full dose MDMA as an adjunct to psychotherapy. The first two subjects were enrolled in the open label full dose lead-in with 125 mg of MDMA, followed 1.5 to 2.5 hours later by a supplemental half-dose of 62.5 mg of MDMA. The remaining eight subjects enrolled in Stage 1 of the study and received either an active placebo dose (low dose of 25 mg MDMA, with a supplemental dose of 12.5 mg MDMA) or a fully active dose of MDMA (125 mg, with a supplemental dose of 62.5 mg MDMA) during two experimental psychotherapy session, each lasting six to eight hours and scheduled three to five weeks apart. The extent of PTSD symptoms was assessed at baseline and two months after the second experimental session using the Clinician Administered PTSD Scale (CAPS) [Blake et al., 1995]. Subjects who enrolled in Stage 1 and received the active placebo had the opportunity to enroll in Stage 2 of the study and complete open-label experimental sessions with the fully active dose of MDMA on the same schedule as Stage 1.
Detailed Description

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder that can develop after a person experiences a traumatic event, such as sexual assault, war, or any other life-threatening event. PTSD is a worldwide health problem that severely reduces a person's quality of life and is associated with high rates of psychiatric and medical comorbidity, disability, suffering, and suicide. At least a third of PTSD patients fail to respond to established PTSD psychotherapies. A wider array of effective treatments for PTSD are needed.

3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy may be a potential treatment option for PTSD. MDMA is a monoamine releaser that affects serotonin, norepinephrine, and dopamine. MDMA is capable of inducing unique psychopharmacological effects such as decreased feelings of fear, increased feelings of wellbeing, increased sociability and extroversion, increased interpersonal trust, and an alert state of consciousness. In the U.S., MDMA was used as an adjunct to psychotherapy by a considerable number of psychiatrists and therapists before it was placed in Schedule I in 1985 as a result of non-medical use.

This randomized, double-blind, active placebo-controlled Phase 2 pilot study investigated the safety and efficacy of MDMA-assisted psychotherapy in 10 people with chronic, treatment-resistant posttraumatic stress disorder (PTSD), comparing the effects of low and full dose MDMA as an adjunct to psychotherapy. The first two subjects were enrolled in the open label full dose lead-in with 125 mg of MDMA, followed by a supplemental half-dose of 62.5 mg of MDMA after 1.5 to 2.5 hours. The remaining eight subjects enrolled in Stage 1 of the study and received either an active placebo dose (low dose of 25 mg MDMA with a supplemental half-dose of 12.5 mg MDMA) or a fully active dose (125 mg MDMA with a supplemental half-dose of 62.5 mg MDMA) during two experimental psychotherapy session, each lasting six to eight hours and scheduled three to five weeks apart.

Subjects remained with their male/female co-therapist team for the entirety of the study. Upon enrollment, subjects met with their therapist team for three preparatory sessions. After each MDMA-assisted psychotherapy session, subjects met with their therapist team for integrative psychotherapy sessions where subjects processed and connected their thoughts and feelings about the experience.

The extent of PTSD symptoms was assessed at baseline and two months after the second experimental session using the Clinician Administered PTSD Scale (CAPS) (Blake et al., 1995). Safety measures, vital signs, and a measurement of psychological distress was assessed during all experimental sessions. Blood pressure and heart rate were assessed periodically during each experimental session.

Subjects who enrolled in Stage 1 and received the active placebo had the opportunity to enroll in Stage 2 of the study and complete open-label experimental sessions with the fully active dose of MDMA (125 mg and 62.5 mg supplemental) on the same schedule as Stage 1.
