mdma-assisted cognitive processing therapy versus cognitive processing therapy for veterans with severe posttraumatic stress disorder

Conditions: PTSD

Summary: 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.

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. ptsd carries a high public burden, both economically and socially, by increased healthcare utilization, use of social services, lost wages, and disability payments. given the chronicity of ptsd, low treatment compliance evidenced by high dropouts, and limited recovery with current medications contributing to serious outcomes, ptsd patients exhibit an unmet medical need. currently, the va serves approximately nine million veterans and the conservative estimate of those with ptsd is 25%, or over two million veterans. the potential importance and benefits of this novel treatment to veterans, doctors, researchers, and the va system cannot be underestimated. the clinical effectiveness, implementation evaluation, and economic assessment conducted in this study will provide critical information and understanding of the feasibility of utilization in the va system.
