Overview

Despite being exposed to a high level of potentially traumatic experiences due to exposure to combat, military veterans have poor response rates to traditional PTSD treatments, in some reports, just 1/3 of veterans recover using traditional treatments. In recent years 3,4-methylenedioxymethamphetamine (MDMA), a psychedelic drug has demonstrated a significant treatment potential for severe and treatment resistant PTSD though not specifically in a veteran population. Additionally, even in groups where participants receive a placebo, the effect of the psychedelic treatment formulation, intensive, focused and respectful structure, appears to have promising effects. Indeed, in the current psychedelic literature, the setting and mind with which participant approach psychedelic therapy, significantly contributes to the treatment effect.

The current study proposes to address the major gaps in the theoretical literature by examining the proposed mechanisms by which MDMA enhances the "window of tolerance" for PTSD therapy, specifically in those with comorbid symptoms of moral injury; namely by reducing hyperarousal and enhancing connection (to self and others) and whether MDMA assisted therapy is more successful in reducing PTSD in veterans compared to a matched somatic experiential PTSD treatment, Somatic Experiental Acceptance Intensive Trauma-based therapy, (SEA-IT) which builds upon the promising placebo results, enhancing them with somatic and acceptance based treatment protocols.

Medical History

        10. At Screening, meet diagnostic criteria (Diagnostic Statisticians Manual, 5th version,
        DSM-5) for current military-based PTSD with a symptom duration of 6 months or longer with a
        history of at least one attempt at psychiatric or psychological treatment.
        11. At Screening, have a PCL-5 total score of 33 or greater and at Screening/Baseline a
        confirmed diagnosis of PTSD per CAPS-5 and a total severity score of 28 or greater.
        12. Have a body weight of at least 45 kilograms. Participants with a body weight of 45 to
        48 kg must also have a body mass index (BMI) within the range of 18 to 30 kg/m2.
        13. Capable of giving signed informed consent.
        Exclusion Criteria:
        - Medical Conditions
          1. Alanine transaminase (ALT) [or aspartate transaminase (AST)]higher than 2 x upper
             limit of normal (ULN).
          2. Total bilirubin higher than 1.5 x ULN (isolated bilirubin higher than; 1.5 x ULN is
             acceptable if total bilirubin is fractionated and direct bilirubin less than; 35%).
          3. Current unstable liver or biliary disease per investigator assessment defined by the
             presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or
             gastric varices, persistent jaundice, or cirrhosis.
             • Note: Stable chronic liver disease (including Gilbert's syndrome, asymptomatic
             gallstones, and chronic stable hepatitis B (e.g., the presence of hepatitis B surface
             antigen or positive hepatitis C antibody test result without evidence of active
             infection at screening or within 3 months prior to starting study intervention) is
             acceptable if the participant otherwise meets entry criteria.
          4. Have a recent history of clinically significant hyponatremia or hyperthermia.
          5. Have a marked baseline QTcF (QT interval corrected for heart rate ) interval higher
             than 450 ms demonstrated on repeated ECG (electrocardiogram) assessments. Participants
             whose QTcF exceeds this value during screening may be initially enrolled if a
             pre-study concomitant medication is suspected to be prolonging the QT-interval. ECGs
             should be repeated after initial enrollment and tapering off the pre-study concomitant
             medication to ensure the participant meets eligibility criteria prior to enrolment
             confirmation and to IMP dosing.
             • Note: The QTcF is the QT interval corrected for heart rate according to Fridericia's
             formula. It is either machine-read or manually over-read.
          6. 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, heart
             failure, severe coronary artery disease, or aneurysm.
               -  Participants with other mild, stable chronic medical problems may be enrolled if
                  the study clinician and Sponsor Investigator (S-I) 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 MDMA.
               -  Examples of stable medical conditions that could be allowed include but are not
                  limited to human immunodeficiency virus (HIV) infection, gastroesophageal reflux
                  disease (GERD), hypothyroidism (if taking adequate and stable thyroid replacement
                  medication), glaucoma (if approval for study participation is received from an
                  ophthalmologist). Any medical disorder judged by the investigator to
                  significantly increase the risk of harm from MDMA exposure by any mechanism would
                  require exclusion.
          7. Have a diagnosis of uncontrolled hypertension, defined as repeated blood pressure
             readings of ≥140 mmHg systolic or ≥90 mmHg diastolic. The diagnosis may be confirmed
             by repeated clinic measurements or home blood pressure monitoring if clinically
             indicated.
             • Participants with well-controlled hypertension that has been successfully treated
             with anti-hypertensive medicines may be enrolled if they pass a risk assessment and
             potentially additional screening to rule out underlying cardiovascular disease.
          8. Have a history of ventricular arrhythmia at any time, other than occasional premature
             ventricular contractions (PVCs) in the absence of ischemic heart disease.
          9. Have Wolff-Parkinson-White syndrome or any other accessory pathway that has not been
             successfully eliminated by ablation.
         10. Have a history of arrhythmia, other than premature atrial contractions (PACs) or
             occasional PVCs in the absence of ischemic heart disease, within 12 months of
             screening.
             • Participants with a history of atrial fibrillation, atrial tachycardia, atrial
             flutter or paroxysmal supraventricular tachycardia or any other arrhythmia associated
             with a bypass tract may be enrolled only if they have been successfully treated with
             ablation and have not had recurrent arrhythmia for at least one year off all
             antiarrhythmic drugs, as confirmed by a cardiologist.
         11. Have a history of additional risk factors for Torsade de pointes (e.g., heart failure,

             Period, to be re-exposed to their index trauma or other significant trauma during the
             study.
         14. Have a current moderate (not in early remission in the 3 months prior to enrollment
             and meets at least 5 of 11 diagnostic criteria per DSM-5) or severe alcohol or
             cannabis use disorder within the 12 months prior to enrollment (meets at least 6 of 11
             diagnostic criteria per DSM-5).
             • May have current mild alcohol or cannabis use disorder (meets 3 of 11 diagnostic
             criteria per DSM-5) or moderate alcohol or cannabis use disorder in early remission
             for the 3 months prior to enrollment (meets 4 or 5 of 11 diagnostic criteria per
             DSM-5).
         15. Have an active illicit drug (other than cannabis) or prescription drug substance use
             disorder at any severity within 12 months prior to enrollment.

             psychiatric interview, responses to Columbia Suicide Severity Rating Scale (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/Screening C-SSRS will be excluded:
               -  Suicidal ideation score of 4 or greater within the last month of the assessment
                  at a frequency of once a week or more.
               -  Suicidal ideation score of 5 within the last 6 months of the assessment.
               -  Any suicidal behavior, including suicide attempts or preparatory acts, within the
                  last 6 months of the assessment. Participants with non-suicidal self-injurious

             clinician, might interfere with study participation.
        Security Criteria
        The current study dealing with intensive treatment of military veterans suffering from
        PTSD, requires an environment of physical and emotional security for the patients. Safety
        is critical in the success of the treatment. Since October 7, 2023, we have been in a
        continuous state of war, which we do not know when it will end. Therefore, we are required
        at this time to define what security is as a criterion for conducting research at this
        time, and in relation to the normative reality in the world and in the State of Israel in
        particular. Therefore:
          1. The research will be carried out in Jerusalem and long sessions will not take place
             when there is a high risk of rocket attack or sirens during the previous day/night.
          2. The participants in the study will be military veterans who do not participate or have
             taken an operational part in the war in the three months prior to the start of their
             participation in the study.
          3. The participants in the study do not have first degree relatives or a partner who are
             actively serving in a war zone at the time of their participation in the study.
          4. The participants live in a permanent and safe place and are not expected to change
             their place of residence during their participation in the study.
