• Agree to refrain from using any psychoactive drugs, including alcoholic beverages, ondansetron, cannabis, and non-routine PRN medications within 24 hours of each psilocybin administration. Exceptions include daily use of caffeine, nicotine, and opioid pain medication (see Section 6.2.2).
• Agree that for one week preceding the psilocybin session, he/she will refrain from taking any nonprescription medication, nutritional supplement, or herbal supplement except when approved by the research team. Exceptions will be evaluated by the research team and will include acetaminophen, non-steroidal anti-inflammatory drugs, and common doses of vitamins and minerals.

If the subject does not routinely consume caffeinated beverages, he or she must agree not to do so on the day of psilocybin administration.
• Subjects requiring opioid use for pain are on a stable pain management regimen. Long-acting opioid medications (e.g., oxycodone sustained-release, morphine sustained release) will be allowed if the last dose occurred at least 6 hours before psilocybin administration; such medication will not be taken again until at least 6 hours after psilocybin administration.

Exclusion Criteria:

• Personal history or immediate family members with schizophrenia, bipolar affective disorder, delusional disorder, schizoaffective disorder, psychosis, or other psychotic spectrum illness.
• Currently meeting DSM-V criteria for Dissociative Disorder, or other psychiatric conditions judged to be incompatible with the establishment of rapport or safe exposure to psilocybin.

• The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions:

  • Cardiovascular disorders:

    • Congestive heart failure New York Heart Association Class III or IV
    • Unstable angina pectoris, cardiac hypertrophy, cardiac ischemia, myocardial infarction
    • Uncontrolled hypertension at time of enrollment (BP>140 systolic or 90 diastolic), coronary artery disease, artificial heart valve
    • Prolonged or congenital long QT syndrome (≥480 ms), serious cardiac arrhythmias, tachycardia, a clinically significant screening ECG abnormality

  • Renal insufficiency as defined as creatinine clearance < 40 mL/min calculated by Cockcroft-Gault formula:

    • Males: ((140-age)×weight[kg])/(serum creatinine [mg/dL]×72)
    • Females: (((140-age)×weight[kg])/(serum creatinine [mg/dL]×72))×0.85

  • Hepatic disorders:

    • Active infection including hepatitis B (known positive HBV surface antigen (HBsAg) result) or hepatitis C.
    • Note: Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
  • Any other condition that would, in the Investigator's judgment, contraindicate the subject's participation in the clinical study due to safety concerns or compliance with clinical study procedures (e.g., infection/inflammation, intestinal obstruction, unable to swallow medication, [patients may not receive the drug through a feeding tube], social/ psychological issues, etc.)
• Known prior severe hypersensitivity to investigational product or any component in its formulations (NCI CTCAE v5.0 Grade ≥ 3).
