简要总结
In partnership with the Veterans Affairs (VA) Palo Alto Health Care System and Stanford University, this study aims to evaluate clinical outcomes, assess implementation feasibility, and health economics of MDMA-assisted Cognitive Processing Therapy (MDMA-aCPT) in the treatment of posttraumatic stress disorder (PTSD). Through a randomized comparison of MDMA-aCPT versus Cognitive Processing Therapy (CPT), a VA gold standard treatment for PTSD, the proposed study will set the stage for understanding the potential use and application of MDMA-aCPT for PTSD within the VA system.
详细描述
Posttraumatic stress disorder (PTSD) is a serious debilitating disorder that negatively impacts a person's daily life, and can result in diminished cognitive and psychosocial functioning, fractured relationships, inability to maintain employment, substance use disorders, high-cost healthcare utilization, increased depression, and suicide risk. People who suffer from PTSD relive their traumatic experience(s) through nightmares and flashbacks, have difficulty sleeping, and feel detached or estranged. Symptoms can be severe and long lasting.
Many available PTSD treatments, including medications and therapy, effectively treat only a fraction of people who try them. This indicates a need to assess treatments targeting durable remission of PTSD. An extensive list of medications, namely antipsychotics, anxiolytics, antidepressants, and sleep aids, are frequently prescribed off-label but are minimally effective in reducing PTSD symptoms.
Cognitive Processing Therapy (CPT) is a cognitively-oriented approach to treating PTSD developed in the late 1980's by Dr. Patricia Resick. Significant research on CPT has been conducted in the VA system nationally. Across a number of studies, a meta-analysis found the number of subjects that no longer meet PTSD criteria after receiving a full course of CPT ranged from 30% to 97%, and 51% of subjects receiving CPT achieved loss of diagnosis compared to waitlist, self-help booklets, and treatment as usual control groups. There are various task forces and active efforts to deploy CPT more broadly in the VA.
MDMA-assisted cognitive processing therapy (MDMA-aCPT) is a novel treatment package that combines standard CPT with the administration of MDMA (3,4-methylenedioxymethamphetamine) during medication sessions separate from CPT sessions. This includes the regular course of 8-15 CPT sessions, three sessions during which MDMA is used, and an additional one 'preparatory' session and three 'integration' sessions without the use of medication. Data from a series of Phase 2 and Phase 3 studies of MDMA-assisted therapy provide preliminary evidence suggesting that chronic PTSD symptoms are improved by up to three sessions of MDMA-assisted therapy and associated non-drug preparatory and integrative therapy sessions.
Our goal is to learn how MDMA-aCPT compares to CPT in reducing PTSD symptoms among Veterans. Comparing MDMA-aCPT and CPT for the treatment of PTSD is particularly important due to the urgent need for effective treatments within the VA system.

研究组 & 干预措施
MDMA-assisted Cognitive Processing Therapy (MDMA-aCPT)
This arm consists of 8-15 virtual CPT sessions (average of 12), one 90-minute, non-drug Preparatory Session, three Experimental Sessions with MDMA (~8 hours), and three 90-minute, non-drug Integration Sessions, occurring over a 9-15-week Treatment Period. Standardized homework is assigned at each CPT session to promote the practice of the skills taught in the session. Participants will receive 80mg MDMA HCl for the first Experimental Session and will have the option of a supplemental dose of 40mg MDMA HCI 1.5-2 hours after the initial dose. For the second and third Experimental Sessions, participants will receive either 80mg or 120mg MDMA HCl as the initial dose, and an optional supplemental dose of 40mg or 60mg MDMA HCl 1.5-2 hours after the initial dose. Participants interested in receiving CPT treatment alone after study completion will have the option to be referred to their local VA PTSD Clinical Team for services 6 months after all study visits are completed.

Cognitive processing therapy
This arm consists of 8-15 virtual CPT treatment sessions lasting approximately 1-1.5 hours, occurring over a ~12-16-week Treatment Period. These sessions will take place approximately one week apart. Standardized homework is assigned at each session to promote the practice of the skills taught in the session. Participants will have the option to crossover to the MDMA-aCPT arm 6 months after all study visits are completed.

结局指标
主要结局
Change in Clinician Administered PTSD Scale (CAPS-5) Total Severity Score
时间窗: From Baseline to approximately 4 months post-baseline
The Primary Outcome measure will be the change in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Total Severity Score from Baseline to 4 months post-baseline assessed by a blinded study staff rater. 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.
次要结局
- Change in Quality of Life Enjoyment and Satisfaction Questionnaire(From Baseline to approximately 4 months post-baseline)
