About this study

This study is designed to provide information on whether the drug MDMA, combined with Cognitive Processing Therapy (CPT), is safe and helpful for people with Post Traumatic Stress Disorder (PTSD). PTSD is a serious debilitating disorder that negatively impacts a person's daily life, and can result in diminished functioning, fractured relationships, inability to maintain employment, substance abuse, 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.

CPT is a manualized treatment for PTSD, which has the participant make meaning of the traumatic event and its impact on their life. CPT is one of the treatments with the best evidence for the treatment of PTSD to date. Clients with PTSD discuss how they believe the trauma has impacted them, and the therapist teaches the client skills to challenge areas where they are "stuck" remembering the traumatic event.

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 CPT. Given the properties of MDMA, specifically in inducing the ability to stay with emotion and challenging cognitions, these effects are especially relevant to the mechanisms of CPT.

This is a pilot study exploring CPT integrated with MDMA-assisted psychotherapy for treatment of PTSD. This study will enroll 10 participants diagnosed with PTSD, who will undergo a 2-month course of psychotherapy that includes CPT integrated with MDMA-assisted psychotherapy. Participants will go through CPT sessions, and two doses of MDMA will be used as an adjunct to psychotherapy. Since this is the first time that CPT is being combined with individual MDMA-assisted psychotherapy for PTSD, the researchers are interested in gathering preliminary information about the blending of these two therapeutic approaches.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline to Primary Endpoint in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Score

    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.

    Measured: Baseline (enrolment) to endpoint (6 month follow up)

  2. Change From Baseline to Midpoint (visit 6) in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Score

    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.

    Measured: Baseline (enrolment) to midpoint (visit 6, 3-4 weeks)

  3. Change From Baseline to 1 Month Follow up in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Score

Secondary outcomes (8)
  1. Change From Baseline to Endpoint in PTSD Symptoms Checklist

    PTSD Checklist for the DSM-5 (PCL-5) is a self-report questionnaire in which respondents indicate the presence and severity of PTSD symptoms, derived from the DSM-5 symptoms of PTSD. Participants indicate how much distress they have experienced due to symptoms on a five-point Likert-type scale (1 = not at all, 5 = extremely). The total PCL-5 score (a sum of all 20 items) provides an index of overall PTSD symptom severity with higher scores indicating higher severity.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MDMA in people with Post Traumatic Stress Disorder, run by Remedy at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline to Primary Endpoint in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Score (time frame: Baseline (enrolment) to endpoint (6 month follow up)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2024; AzTrials last refreshed its copy on 31 Oct 2026.
