Who cannot take part

  • Taking any contraindicated medications: antidepressants, mood stabilizers, antipsychotics, stimulants. No patient will be encouraged to discontinue medications for the study. We will allow people to participate who stopped contraindicated medications at least five half-lives before baseline assessments
  • History of bipolar disorder, schizophrenia or schizoaffective disorder or currently exhibiting psychotic features as determined by the Structured Clinical Interview for DSM5 (SCID-5) and/or clinician assessment
  • Any current substance use disorder (in the last 1 month) per SCID interview for alcohol or non-alcohol substances; or a positive pre-study (screening) urine drug screen
  • Any severe substance use disorder during the last 6 months
  • History of valvulopathy or pulmonary hypertension (due to evidence of 5HT2B receptor agonism by MDMA)
  • History of uncontrolled hypertension with baseline blood pressure above 130 mmHg (systolic) and over 90 mmHg (diastolic). Any history of syncope and/or study baseline blood pressure below 90 mmHg (systolic)
  • History of tachycardia with baseline heart rate above 90 beats per minute
  • Any significant history of serious medical or neurological illness (including history of stroke, myocardial infarction, heart failure, cardiac arrhythmia, diabetes, family history of long-QT syndrome, etc.)
  • Any signs of major medical or neurological illness on examination, ECG screening, or laboratory tests. For QTc, we would exclude for QTcf >450. For liver function tests (AST, ALT), we will exclude for values more than 2.5 times the upper limit of normal range for our laboratory. For kidney function, we would exclude for eGFR < 90 (n.b. our laboratory does use the contemporary non-race based formula for eGFR). Clinically significant electrolyte imbalances (sodium, potassium values out of range) will also be exclusionary (clinical significance to be determined by study MD review). A participant with a clinical abnormality may be included only if the study physician considers the abnormality will not introduce additional risk factors and will not interfere with the study procedure
  • Hypersensitivity to non-MDMA ingredients of the investigational medicine product (IMP), namely mannitol, magnesium stearate, and hydroxypropylmethylcellulose
