About

This clinical research study is to learn about the feasibility, safety, and effects of psilocybin-assisted psychotherapy for cancer survivors with depression and/or anxiety.

Full description

Primary Objective:

To examine the feasibility, safety, effect size estimates of psilocybin-assisted psychotherapy for cancer survivor patients with depression and/or anxiety. Feasibility will be measured as: At least 20% of eligible patients consent (inclusion rate), at least 60% of consented patients completing the two doses of treatment (treatment completion rate), and at least 80% and 65% consenting patients completing assessments at the 2- and 6-month follow-ups (adherence rates), respectively.

Secondary Objectives:

Determine whether psilocybin-assisted psychotherapy improves measures of quality of life (e.g., sleep, pain, functional status) and psychosocial well-being (e.g., finding meaning and post-traumatic growth), as measured by the following: PHQ-9, GAD-7, PROMIS-10, PROMIS-A, PROMIS-D, MEQ30 (mystical experience), Flourishing scale, mDES, PIQ (altered states), and Posttraumatic Growth Inventory.
Determine whether psilocybin-assisted psychotherapy improves functional status per clinician-rated outcome measures.
Measure the change in inflammatory markers (IL6, TNF, and CRP) and in frequency and activation status of peripheral immune cell populations assessed by immune monitoring through flow cytometry.
Examine changes in central nervous system plasticity through the use of fMRI, specifically changes in 5-HT2A-rich and higher-order functional networks, as well as a global increase in brain network integration.
Evaluate the Impact on MDASI measurements.

Inclusion criteria

Subjects must have solid or hematological malignancy that does not involve the brain.

Agree to abstain from any nicotine products for at least 8 hours prior to fMRI performance.
Refrain from any psychoactive drugs (including alcohol) for 48 hours prior to psilocybin sessions and must refrain from psychoactive drugs 12 hours after psilocybin sessions. Must consent to urine drug screen (UDS) which will be given before receiving psilocybin. Participants with positive drug test will be retested (UDS) after 6 weeks and included if the repeated UDS is negative. Patient tested positive for a prescribed substance are eligible. Patient failing on the 2nd test (UDS) will be excluded.
Must be free from any regularly scheduled psychotropic (antidepressant/anxiolytic class) medications for a minimum of 2 weeks prior to study. Intermittent or PRN use of short-acting anxiolytics or and anti-nausea medications (e.g., ondansetron) may be permitted as defined below in exclusionary criteria). Ondansetron could be taken but must be stopped at least 24 hours before psilocybin administration.
Inhibitors of monoamine oxidase, UGT1A9, 1A10, and aldehyde or alcohol dehydrogenase should be discontinued 5 half-lives prior to active dose of psilocybin.
Eligible subjects will have a third-party transportation by a licenses driver (e.g. friend, family or a driver) after the psilocybin session is complete. If a driver is used, a friend or family member must accompany them in the vehicle home
Fluent in Englishria). Ondansetron could be taken but must be stopped at least 24 hours before psilocybin administration.

Exclusion criteria

Clinically significant suicidality or high risk of completed suicide defined as:

i. Answer 'Yes' to C-SSRS Suicidal Ideation items 4 or 5 within the last 2 months at Screening or 'since last visit' at Baseline ii. Report having had any C-SSRS Suicidal Behavior item within the past 12 months at Screening or 'since last visit' at Baseline, as defined by 'Yes' to any of the following on the C-SSRS: actual attempt, interrupted attempt, aborted attempt, or preparatory acts iii. Have any suicidal ideation or thoughts, in the opinion of the study physician or PI, that presents a serious risk of suicidal or self injurious behavior
History of bipolar disorder, psychosis (including a history of schizophrenia).
Functionally limiting comorbid conditions such as second primary malignancies in CNS or chest, and history of total laryngectomy or total glossectomy precluding them from communicating.
The effects of psilocybin on the developing human fetus are unknown. For this reason, pregnant women will be excluded (Urine test for screening), women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstaining from intercourse with the opposite sex) prior to study entry and for the duration of study participation. This includes all female patients, between the onset of menses (as early as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following:
- Postmenopausal (no menses in greater than or equal to 12 consecutive months).
- History of hysterectomy or bilateral salpingo-oophorectomy.
- Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy).
- History of bilateral tubal ligation or another surgical sterilization procedure. Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control.
