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 21 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Volunteers must:
  • Have given written informed consent
  • Have a high school level of education
  • Be 21 to 80 years old
  • Has or has had a cancer diagnosis that is potentially life-threatening. Patients with an active cancer (e.g. stage III or IV with a poor prognosis) or disease progression or recurrence are eligible. Patients who do not have an active cancer or disease progression or disease recurrence are only eligible if at least 1 year has elapsed since their diagnosis.
  • Have an ECOG performance status of 0, 1, or 2.
Show all 13Show fewer
  • Have a DSM-IV psychiatric diagnosis, as determined by the SCID, of one or more of the following Axis I psychiatric disorders that is either precipitated by or exacerbated by the psychological stress of the cancer diagnosis: Generalized Anxiety Disorder; Acute Stress Disorder; Post traumatic Stress Disorder; Major Depressive Disorder (mild or moderate severity); Dysthymic Disorder; Adjustment Disorder with Anxiety; Adjustment Disorder with Depressed Mood; Adjustment Disorder with Mixed Anxiety and Depressed Mood; Adjustment Disorder with Disturbance of Conduct; Adjustment Disorder with Disturbance of Emotions and Conduct. Psychiatric diagnosis will be determined by BPRU staff.
  • Patients receiving chemotherapy, hormonal therapy, radiation therapy, biologic therapies may participate while receiving those therapies. Continuing hormonal therapy, chemotherapy, or radiation treatment is acceptable if the patient is tolerating the therapy or treatment in a sufficient fashion to allow administration of oral psilocybin.
  • Agree that for one week preceding each 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.
  • Agree not to use nicotine for at least 2 hours before psilocybin administration, and not again until questionnaires have been completed approximately 7 hours after psilocybin administration.
  • Agree to consume approximately the same amount of caffeine-containing beverage (e.g., coffee, tea) that he/she consumes on a usual morning, before arriving at the research unit on the mornings of psilocybin session days. If the patient does not routinely consume caffeinated beverages, he or she must agree not to do so on psilocybin session days.
  • Agree not to take any PRN medications on the mornings of psilocybin sessions, with the exception of daily opioid pain medication. Non-routine PRN medications for treating breakthrough pain that were taken in the 24 hours before the psilocybin session may result in rescheduling the treatment session, with the decision at the discretion of the investigators.
  • Agree to refrain from using any psychoactive drugs, including alcoholic beverages, within 24 hours of each psilocybin administration. As described elsewhere, exceptions include daily use of caffeine, nicotine, and opioid pain medication.

  • Known paraneoplastic syndrome or "ectopic" hormone production by the primary tumor such as the patient could have or be at risk for hypercalcemia, Cushing's syndrome, hypoglycemia, syndrome of inappropriate antidiuretic hormone secretion, or carcinoid syndrome
  • Cardiovascular conditions: uncontrolled hypertension, angina, a clinically significant ECG abnormality (e.g. atrial fibrillation), TIA in the last 6 months, stroke, peripheral or pulmonary vascular disease (no active claudication)
  • Blood pressure exceeding screening criteria described below
  • Epilepsy with history of seizures
  • Renal disease (creatinine clearance < 40 ml/min using the Cockcroft and Gault equation)

  • Currently taking on a regular (e.g., daily) basis: investigational agents, psychoactive prescription medications (e.g., benzodiazepines), medications having a primary pharmacological effect on serotonin neurons (e.g., ondansetron), or medications that are MAO inhibitors. Long-acting opioid pain medications (e.g. oxycodone sustained release, morphine sustained release -- which are usually taken at 12 hour intervals) 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.
  • For individuals who have intermittent or PRN use of investigational agents, psychoactive prescription medications, medications having a primary pharmacological effect on serotonin neurons, or medications that are MAO inhibitors, psilocybin sessions will not be conducted until at least 5 half-lives of the agent have elapsed after the last dose.
  • In addition to the foregoing, patients will be excluded if they are currently using any the following of potent metabolic inducers or inhibitors: Inducers - Rifamycin (rifampin, rifabutin, rifapentine), anticonvulsants (carbamazepine, phenytoin, Phenobarbital), Nevirapine, Efavirenz, Taxol, Dexamethasone), St Johns Wort; Inhibitors - all HIV protease inhibitors, itraconazole, ketoconazole, erythromycin, clarithromycin, troleandomycin.

  • Psychiatric Exclusion Criteria
  • Individuals with severity of depression or anxiety symptoms warranting immediate treatment with antidepressant or daily anxiolytic medication (e.g., due to suicidal ideation). We will interview patients to determine if referral (e.g., to Community Psychiatry) is necessary. For all individuals who are consented and screened, we will notify the referring physician as to: 1) whether the individual enrolled in the study or not, and 2) if disqualified, why the individual was disqualified. If disqualification was based on severe depression or anxiety (e.g., suicidal ideation), this will be included in the information conveyed to the referring physician. Permission for this contact will be obtained from the participant.
  • Current or past history of meeting DSM-IV criteria for Schizophrenia, Psychotic Disorder (unless substance-induced or due to a medical condition), or Bipolar I or II Disorder
  • Current or past history within the last 5 year of meeting DSM-IV criteria for alcohol or drug dependence (excluding caffeine and nicotine).
  • Have a first or second degree relative with schizophrenia, psychotic disorder (unless substance induced or due to a medical condition), or bipolar I or II disorder.
  • Currently meets DSM-IV criteria for Dissociative Disorder, Anorexia Nervosa, Bulimia Nervosa, or other psychiatric conditions judged to be incompatible with establishment of rapport or safe exposure to psilocybin.
  • Cardiovascular screening:
  • There will be at least four blood pressure assessment occasions over at least two separate days. Within a day, assessment occasions will be separated by at least 15 minutes. Each assessment occasion will involve two or more blood pressure readings. To qualify for the study, the mean blood pressure (mm Hg) of the four or more assessment occasions will not exceed 140 systolic and 90 diastolic.
  • Blood pressure will be taken while subjects are at rest and have been seated or supine for at least 5 minutes. As recommended by the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure, these assessments will involve the average of 2 or more readings separated by two minutes. If the first 2 readings differ by more than 5 mm Hg, additional readings will be obtained and averaged. On one or more of the blood pressure measurement occasions, the volunteer will be acclimated to the automated blood pressure monitoring equipment by repeatedly taking blood pressure (at least 3 readings) with the device. Because it has been our experience that time-to-time blood pressure readings with the automated equipment can be variable due to measurement artifact, any reading that initially exceeds our threshold value will be reassessed twice within 4 minutes to assure accuracy.

Read the detailed description

This research is being done to study the psychological effects of psilocybin in cancer patients. Psilocybin is a naturally occurring substance found in some mushrooms that some cultures have used for centuries in religious practices. Psilocybin has not been approved for general medical use by the U.S. Food and Drug Administration (FDA). Its use in this study is investigational. Psilocybin is a mood-altering drug with effects similar to other hallucinogens like LSD and mescaline. Mescaline is the main psychoactive component of the peyote cactus used in Native American religious practices. Such substances have been used for centuries in some cultures as a way of inducing non-ordinary states of consciousness for religious and spiritual purposes.

An earlier study that was done in our lab with healthy participants found that psilocybin, given in a comfortable and supportive setting, can provide an experience that is personally and spiritually meaningful for the participant. This study is being done to find out if psilocybin can also produce personally and spiritually meaningful experiences in cancer patients. This could be important because spirituality has been associated with increased psychological coping and decreased depression in serious illness. People with a diagnosis of cancer between the ages of 21 and 80 years old and who meet the medical requirements may join. About 44 people are expected to take part in this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. GRID-HAM-D-17 -- Structured Interview Guide for the Hamilton Depression Scale.

    The GRID-Hamilton Depression Rating Scale is a 17-item clinician-administered rating scale designed to assess severity of depressive symptoms. The score range for the GRID-HAMD is 0 to 52, with higher score indicating more severe depression. For this clinician-rated measure, a clinically significant response was defined as ⩾50% decrease in measure relative to Baseline; symptom remission was defined as ⩾50% decrease in measure relative to Baseline and a score of ⩽7 on the GRID-HAMD

    Measured: Baseline, 5 weeks post session 1 and 2, 6-month follow-up

  2. HAM-A Assessed With the SIGH-A -- a Structured Interview Guide for the Hamilton Anxiety Rating Scale (SIGH-A).

    The Hamilton Anxiety Rating Scale is a 14-item clinician-administered rating scale designed to assess severity of anxiety symptoms. The score range for the HAM-A is 0 to 56, with higher score indicating more severe anxiety.

    For this clinician-rated measure, a clinically significant response was defined as ⩾50% decrease in measure relative to Baseline; symptom remission was defined as ⩾50% decrease in measure relative to Baseline and a score of ⩽7 on the GRID-HAM-A

    Measured: Baseline, 5 weeks post session 1 and 2, 6-month follow-up
