Group vs Individual MDMA-Assisted Therapy for PTSD After the October 7, 2023 Events

This Phase II, randomised, open-label, non-inferiority trial (n=168) will evaluate the safety, tolerability and effectiveness of group-based MDMA-assisted therapy compared with individual MDMA-assisted therapy in adults (18–75 years) with PTSD diagnosed following the events of 7 October 2023. The primary outcomes are change in PTSD symptoms measured by CAPS-5 and PCL-5 from baseline to end-of-treatment (Week 17 in the group-based arm; Week 13 in the individual arm). Eligible participants will be randomised to either group-based MDMA-assisted therapy (groups of up to 7 participants with the same trauma type) or individual MDMA-assisted therapy; both arms include preparatory sessions, three MDMA dosing sessions and integration sessions. MDMA HCl is administered orally in a divided dose with a supplemental dose 1.5 to 2 hours after the initial dose: first dosing session 80 mg with 40 mg supplemental, second and third dosing sessions 120 mg with 60 mg supplemental. Dosing sessions include on-site monitoring of vital signs, overnight stay after sessions and safety assessments (physical exam, urine drug screen, ECG, laboratory tests), with adverse events and suicidality monitored (C-SSRS) and oversight by an external DSMB; estimated enrolment is 168, with study start 24 December 2025 and completion anticipated 31 March 2029.

Detailed Description

The goal of this clinical trial is to evaluate the safety, tolerability and effectiveness of group-based MDMA-assisted therapy compared to individual MDMA-assisted therapy in participants with PTSD, who were diagnosed following the events of 7 October 2023. The main questions it aims to answer are: safety and tolerability? effectiveness? Researchers will compare group-based MDMA-assisted therapy to individual MDMA-assisted therapy to see if group-based MDMA-assisted therapy is not inferior to individual MDMA-assisted therapy, in terms of safety and effectiveness.

Participants will be randomized to one of two study arms: group-based MDMA-assisted therapy or individual MDMA-assisted therapy receive MDMA HCl administered orally in a divided dose. Participate in preparatory sessions, MDMA dosing sessions, and integration sessions. Be monitored for adverse events and suicidality (C-SSRS). Be monitored by an external Data Safety Monitoring Board (DSMB).

Agree to the following lifestyle modifications (see lifestyle modifications section) : comply with requirements for fasting and refraining from certain medications prior to Experimental Sessions, not participate in any other interventional clinical trials during the duration of the study, remain overnight at the study site after each Experimental Session and be driven home after, and commit to medication dosing, therapy, and study procedures.
  • 10. If able to become pregnant (i.e. assigned female at birth, fertile, following menarche and until becoming post-menopausal unless permanently sterile), must have a highly sensitive negative pregnancy test at study entry and prior to each Experimental Session, and must agree to use adequate birth control through 10 days after the last Experimental Session. Adequate birth control methods include intrauterine device (IUD), injected, implanted, intravaginal, or transdermal hormonal methods, abstinence, oral hormones plus a barrier contraception, vasectomized sole partner, or double barrier contraception. Two forms of contraception are required with any barrier method or oral hormones (i.e. condom plus diaphragm, condom or diaphragm plus spermicide, oral hormonal contraceptives plus spermicide or condom).
  • 11. Holds a permanent address in the next 6 months.
  • Medical History
  • 1. May have well-controlled hypertension that has been successfully treated with anti-hypertensive medicines, if they pass additional screening to rule out underlying cardiovascular disease.

  • 6. Any participant presenting current serious suicide risk, as determined through psychiatric interview, responses to C-SSRS, and clinical judgment of the investigator will be excluded; however, history of suicide attempts is not an exclusion. Any participant who is likely to require hospitalization related to suicidal ideation and behavior, in the judgment of the investigator, will not be enrolled. Any participant presenting with the following on the Baseline C-SSRS will be excluded:
  • 1. Suicidal ideation score of 4 or greater within the last 6 months of the assessment at a frequency of once a week or more.
  • 2. Suicidal ideation score of 5 within the last 6 months of the assessment.

  • Medical History
  • 1. Have a history of any medical condition that could make receiving a sympathomimetic drug harmful because of increases in blood pressure and heart rate. This includes, but is not limited to, a history of myocardial infarction, cerebrovascular accident, or aneurysm. Participants with other mild, stable chronic medical problems may be enrolled if the study physician and sponsor-investigator agree the condition would not significantly increase the risk of MDMA administration or be likely to produce significant symptoms during the study that could interfere with study participation or be confused with side effects of the use of MDMA. Examples of stable medical conditions that could be allowed include, but are not limited to Diabetes Mellitus (Type 2), Human Immunodeficiency Virus (HIV) infection, Gastroesophageal Reflux Disease (GERD), etc. Any medical disorder judged by the investigator to significantly increase the risk of MDMA administration by any mechanism would require exclusion.
