MDMA-Assisted Therapy for Veterans With Moderate to Severe Post Traumatic Stress Disorder
What this study is about
This randomly assigned, where neither patients nor doctors know which treatment is given, single-site phase II 2-treatment group$1 study will investigate the safety and preliminary effectiveness of MDMA-assisted therapy compared with low dose d-amphetamine-assisted therapy on the severity of PTSD symptoms in participants aged 18 years and older with PTSD of at least moderate severity.
View original scientific description
This randomized, double-blind, single-site phase II 2-arm study will investigate the safety and preliminary efficacy of MDMA-assisted therapy compared with low dose d-amphetamine-assisted therapy on the severity of PTSD symptoms in participants aged 18 years and older with PTSD of at least moderate severity.
Interventions
DRUG
3,4-methylenedioxymethamphetamine
Initial doses per Experimental Session include 68 mg or 100 mg MDMA (equivalent to 80 mg or 120 mg MDMA HCl), followed 1.5 to 2 hours later by a supplemental dose of 34 mg or 50 mg MDMA (equivalent to 40 mg or 60 mg MDMA HCl).
DRUG
d-amphetamine
Initial dose per experimental session will be 5 mg or 10 mg d-amphetamine, followed 1.5 to 2 hours later by supplemental dose of 2.5 mg or 5 mg d-amphetamine.
BEHAVIORAL
Therapy
Participants assigned to MDMA and d-amphetamine will undergo a therapeutic approach, which is detailed in the MDMA-Assisted Therapy Treatment Manual and administered by MAPS-trained therapists. In brief, this therapy is guided by the subject's own recollections of traumatic events. The subject and two therapists provide a comfortable and supportive environment and allow the subject to guide the discussion. Subjects are encouraged to experience and express fear, anger, and grief with less likelihood of feeling overwhelmed by these emotions. MDMA seems to engender internal awareness that even painful feelings that arise are an important part of the therapeutic process. In addition, feelings of empathy, love, and deep appreciation often emerge, along with a clearer perspective of the trauma as a past event, a more accurate perspective about its significance, and a heightened awareness of the support and safety that exists in the present.
Primary outcome measures
Compare changes in PTSD symptom severity in the MDMA vs active control group.
Time frame: Visit 17 (approximately 14 weeks after enrollment)
The Primary Outcome measure will be the change in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Total Severity Score from Baseline to Visit 17, 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.

- Able to swallow pills.
- Agree to have study visits audiovisually recorded, including Experimental Sessions, IR assessments, and non-drug therapy sessions.
- Able to provide a contact (relative, spouse, close friend, or other support person) who is willing and able to be reached by the investigators in the event of the participant becoming unwell or unreachable.
- Able to identify appropriate support person(s) to stay with the participant on the evenings of Experimental Sessions if needed.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
