Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Are at least 18 years old
  • Are considered important to their well-being by patient participants (e.g., spouse or close family member)
  • Meet DSM-5 criteria for current AD (no criteria for another mental disorder and does not correspond to an exacerbation of a preexisting mental disorder. Does not represent a normal bereavement)
  • Satisfies diagnostic criteria for AD using the ADNM-2020 (score ≥ 47.5 on the scale)
  • Are able to swallow pills.
  • Are willing to be driven home after the experimental sessions, either by a driver arranged by the participant or by the site personnel or taxi and agree not to drive after each Experimental Session until the therapists deem it safe to do so

  • 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).
  • Must agree to inform the Clinical Investigators within 48 hours of any medical conditions and procedures
  • Are proficient in speaking and reading English
  • Agree to have all clinic visit sessions recorded to audio and video
  • Agree to the following lifestyle modifications (described in more detail in Section 4.3 Lifestyle Modifications): comply with requirements for fasting and refraining from certain medications prior to Experimental Sessions, not enroll in any other interventional clinical trials during the duration of the study, be driven home after each Experimental Session, and commit to medication dosing, therapy, and study procedures.
  • 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.
  • May have asymptomatic Hepatitis C virus (HCV) that has previously undergone evaluation and treatment as needed.
  • May have alcohol or substance use disorder if participant is not in withdrawal or requiring detox. Participants must have a plan, agreed upon by investigator, therapy team, and study physician, to reduce use of alcohol or other substances and to manage symptoms without self-medicating. Enrollment will require that, in the judgment of the investigator, therapy team, and study physician, the plan for decreasing substance use is realistic and has a good chance of succeeding in order to prevent substance use from impacting the safety or efficacy of the investigational treatment.
  • May have a history of or current Diabetes Mellitus (Type 2) if additional screening measures rule out underlying cardiovascular disease, if the condition is judged to be stable on effective management, and with approval by the study physician.
  • May have hypothyroidism if taking adequate and stable thyroid replacement medication.
  • May have a history of, or current, glaucoma if approval for study participation is received from an ophthalmologist.

  • 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, and confirmed by a cardiologist.
  • Have evidence or history of significant (controlled or uncontrolled) hematological, endocrine, cerebrovascular, cardiovascular, coronary, pulmonary, renal, gastrointestinal, immunocompromising, or neurological disease, including seizure disorder, or any other medical disorder judged by the investigator to significantly increase the risk of MDMA administration (participants with hypothyroidism who are on adequate and stable thyroid replacement will not be excluded).
