Brief Summary

This study aims to evaluate the safety, feasibility, acceptability, and effectiveness of MDMA-assisted Cognitive-Behavioral Conjoint Therapy (CBCT) versus CBCT alone for the treatment of Post-Traumatic Stress Disorder (PTSD). PTSD is a debilitating condition that significantly impacts interpersonal relationships and the functioning of individuals and their loved ones. There is also a well-established reciprocal relationship between interpersonal relationships, PTSD, and recovery. CBCT is a manualized treatment for PTSD that simultaneously addresses PTSD symptoms and relationship satisfaction. It provides dyads with behavioral tools to navigate PTSD-related challenges, as well as the knowledge behind PTSD and how it impacts relationships. Previous research has demonstrated the efficacy of CBCT in improving PTSD symptoms, partner functioning, and relationship satisfaction in both distressed and non-distressed dyads. MDMA is a drug commonly used recreationally that has been increasingly studied because of its ability to reduce the impact of PTSD symptoms. The effects of MDMA are reduced fear, enhanced communication, trust and introspection, and increased empathy and compassion. The effects of MDMA create a state that enhances the positive effects of therapy by increasing the ability to tolerate negative emotions and allowing clients to stay engaged in therapy without being overwhelmed by the intense emotions surrounding the memories of traumatic events. It is believed that MDMA may help promote the effects of CBCT due to its ability to induce empathy and interpersonal openness. This randomized study is the second study designed to explore the efficacy of combining MDMA-assisted therapy with CBCT. This study will enroll 30 dyads, where one individual has symptoms of PTSD. Participants will undergo a 7-week psychotherapy course, in MDMA-assisted CBCT or CBCT alone. In the MDMA-assisted CBCT, participants will go through CBCT sessions, and two doses of MDMA will be used as an adjunct to psychotherapy. Participants assigned to the CBCT-only condition will go through CBCT sessions and will have the opportunity to crossover and receive the two MDMA sessions after follow-up. The primary goal of this research is to contribute to the literature on MDMA-assisted CBCT by investigating its feasibility, safety, acceptability, and effectiveness, and by comparing it to active PTSD treatments.

Outcome Measures

Primary Outcomes (5)

  • Feasibility of Intervention Measure (FIM)

    The Feasibility of Intervention Measure (FIM) is a self-report questionnaire in which respondents indicate the extent to which they believe that the treatment can be delivered in a given setting. Respondents indicate their responses on a five-point Likert-type (1=completely disagree, 5= completely agree).

    3-Month Follow-up

  • Safety of Intervention

    Safety will be assessed by examining the frequency and severity of adverse events (AEs), serious AEs (SAEs), treatment emergent AES (TEAEs), and AEs of special interest. Participants are asked to report any AEs, SAEs, TEAEs, and AEs of special interest as they happen and during any communication with the therapist or independent assessor.

    Baseline (enrolment) to Follow-up (3-month follow-up)

  • Intervention Appropriateness Measures (IAM)

    Intervention Appropriateness Measures (IAM) is a self-report measure of the perceived fit, relevance, or compatibility of an intervention. Respondents record their answers on a five-point Likert-type scale (1=completely disagree, 5= completely agree).

    3-month follow-up

  • Long Term Follow-Up Questionnaire (LTFUQ)

    The Long Term Follow-Up Questionnaire (LTFUQ) is a self-report measure that assesses the long-term benefits and harms of MDMA-assisted therapy.

    3-Month Follow-up

  • Clinician Administered PTSD Scale (CAPS-5)

    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 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.

MDMA-Assisted CBCT Condition

EXPERIMENTAL

Dyads will undergo a 7-week course of CBCT psychotherapy for PTSD with two sessions that integrate MDMA-assisted psychotherapy. MDMA will be administered in two separate sessions and integrated into the psychotherapy protocol. The two doses of MDMA during this study will be used as an adjunct to psychotherapy.

Drug: MDMA assisted psychotherapy

CBCT-Only Condition

ACTIVE COMPARATOR

Dyads will undergo a 7-week course of CBCT psychotherapy for PTSD. Dyads who have undergone the CBCT-Only condition will have the option to do a crossover and have the two MDMA sessions after follow-up.

Behavioral: Psychotherapy

Interventions

This treatment combines MDMA with a well researched treatment for PTSD for dyads known as CBCT. Dyads will undergo a 7-week course of psychotherapy with two doses of MDMA will be used as an adjunct to psychotherapy.
