About this trial

The goal of this multi-centre phase I/II open-label, single-arm study is to determine the safety, feasibility, therapeutic dose, and preliminary efficacy of psilocybin microdosing to treat psychological distress among patients with advanced illness. Forty patients will receive psilocybin drug product (1-3mg per day, Mon-Fri) for 4 weeks to be administered via oral capsules by the participant. Feasibility (recruitment rate, rate of intervention and follow-up completion), safety (rate of adverse events), dosing, and preliminary efficacy (depression, anxiety, overall well-being, and global impression of change) will be measured.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients >/=18 years of age

Advanced illness under palliative care management, defined as having 1 to <12 months life expectancy (in the judgment of the palliative care provider)

Experiencing psychological distress, defined as a score of 7 or greater on the Depression, Anxiety or Well-being item of the Edmonton Symptom Assessment System

Ability to understand and communicate in English or French

Disqualifiers

Current or previously diagnosed, or first-degree relative, with psychotic or bipolar disorder

Previously deemed eligible for MAiD with intention to proceed with MAiD regardless of study intervention effectiveness (this criteria is meant to exclude patients who would be unlikely to complete follow-up - those considering or being assessed for MAiD will still be eligible)

Documented or suspected delirium in the past 3 months without a clearly defined reversible cause (e.g. opioid toxicity, infection) and resolution

Documented moderate or severe dementia diagnosis

Trial design

Design model

Single group

Treatments tested in this trial

  • Psilocybin

    Drug

    Phase 1 (week 1): all enrolled participants will take a single 1mg oral dose of psilocybin once per day on Monday and Thursday. If no adverse events are reported at any point during the week (Mon-Fri), the participant will continue to Phase 2 for week 2. Phase 2: The participant will take a single 1mg oral dose of psilocybin once per day for 5 consecutive days (Monday to Friday). If no adverse events are reported at any point during the week (Mon-Fri), the participant will continue to Phase 3 for week 3. Phase 3: The participant will take two 1mg oral doses (2mg total) of psilocybin once per day for 5 consecutive days (Monday to Friday). If no adverse events are reported at any point during the week (Mon-Fri), the participant will continue to Phase 4 for week 4. Phase 4 (maximum allowable dose): The participant will take three 1mg oral doses (3mg total) of psilocybin once per day for 5 consecutive days (Monday to Friday).

Trial outcomes

Primary outcomes

1

Recruitment Rate

Number of patients enrolled divided by number of patients approached

Time frame
Through study completion, up to 1 year
2

Intervention Completion Rate

Number of participants who complete the intervention divided by number of participants enrolled

Time frame
Through study completion, up to 13 months
3

Follow-up Completion Rate

Number of participants who complete follow-up divided by number of participants enrolled

Time frame
Through study completion, up to 18 months
4

Number of Participants With Adverse Events - Change in Blood Pressure

Proportion of participants with systolic blood pressure of \>180mmHg or an increase in 40% from baseline measurements

Time frame
Measured at baseline and daily (Mon-Fri) from enrolment to intervention completion (up to 4 weeks)

Secondary outcomes

1

Existential Distress

Measured using the Demoralization scale II (DS-II), a 16-item questionnaire that measures loss of meaning and purpose, distress, and coping abilities. Each item is rated as a 0 (Never), 1 (Sometimes), or 2 (Often). The 16 items are then summed to create a total score. The highest total score that can be obtained is 32. Higher total scores indicate higher levels of demoralization.

Time frame
Baseline (Friday prior to first dose administered on a Monday); 1 day, 2 week, 4 week, 12 week, 24 week follow-up
2

Psychological distress

Measured by the Hamilton Depression Rating Scale (HDRS), a 17-item questionnaire. We will consider a 50% reduction in score from baseline as achieving clinically meaningful improvement. Each item varies in the maximum value it can be rated at (an item can be rated from 0-2, 0-3, or 0-4). The highest total score that can be obtained is 53. All scores from the 17-items are summed for a total score. Higher total scores indicate increased severity of depression.

Time frame
Baseline (Friday prior to first dose administered on a Monday); 1 day, 2 week, 4 week, 12 week, 24 week follow-up
3

Participant Quality of Life

Measured using the World Health Organization Quality of Life, Brief Version (higher scores indicate higher quality of life)

Time frame
Baseline (Friday prior to first dose administered on a Monday); 1 day, 2 week, 4 week, 12 week, 24 week follow-up
4

Wish to Die

Measured using the Categories of Attitudes Towards Death Occurrence (scored 1-6 with scores 4-6 indicating a wish to die)

Time frame
Baseline (Friday prior to first dose administered on a Monday); 1 day, 2 week, 4 week, 12 week, 24 week follow-up
