Brief summary
This study evaluates whether psilocybin therapy helps patients cope with chronic low back pain more effectively. Patients may be recruited at Stanford and University of California San Francisco (UCSF), study procedures will occur at UCSF. Each participant will receive a dose of psilocybin with possibly one or more other drugs. Participants will undergo two preparation sessions, a dosing session, three integration sessions to discuss their psilocybin experience, and several follow up sessions.
Detailed description
Chronic pain is associated with higher levels of pain-related distress, depression, emotional dysfunction, helplessness, hopelessness, and suicidality. Psilocybin is a psychoactive drug that may be well-suited to easing the psychological and emotional symptoms of distress associated with chronic pain. Previous studies testing psilocybin therapy have shown improvements on multiple behavioral and psychiatric outcomes, but it is unknown whether psilocybin therapy similarly enables patients to cope with chronic pain more effectively. The investigators will determine whether psilocybin therapy improves patients' ability to cope with chronic low back pain. If psilocybin therapy is an effective treatment in this population, its use could be incorporated into interventions for chronic low back pain and other psychological conditions.

Masking description
This trial is testing various doses of psilocybin in combination with add-on medications. Participants, study staff and clinical assessors will be blinded to individual treatment conditions until study close-out. The clinician administered instruments will be administered by different clinical study staff than the facilitators who provide the preparation, psilocybin therapy, and integration sessions.
Intervention model description
All patients will receive a dose of psilocybin between 1-30 mg, and one of the following: placebo, zolpidem, modafinial, or zolpidem and modafinil. All patients will receive two psilocybin preparation sessions , a single dose of psilocybin within a therapeutic environment (6-8 hours), three integration sessions and two follow up visits. All drugs will be orally administered during the dosing session. The study procedures will follow best practices for administering psilocybin in clinical trials.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain interference | Baseline, 1-month after psilocybin session | The Brief Pain Inventory-Interference subscale (BPI) will be used to assess how pain interferes with a variety of daily activities (e.g., walking, lifting, mood, sleep, relationships). Seven items are rated on a scale from 0 (does not interfere) to 10 (completely interferes) for a total possible score ranging from 0 to 70. Higher scores represent greater interference from pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain interference | Baseline, 1-week, and 3-months | The Brief Pain Inventory-Interference subscale (BPI) will be used to assess how pain interferes with a variety of daily activities (e.g., walking, lifting, mood, sleep, relationships). Seven items are rated on a scale from 0 (does not interfere) to 10 (completely interferes) for a total possible score ranging from 0 to 70. Higher scores represent greater interference from pain. |
| Change in average pain intensity | Baseline, 1-week, 1-month, and 3-months after psilocybin session | The Brief Pain Inventory with the Michigan Body Map will be used to assess pain location and worst, least, average, and present pain on a numerical rating scale from 0 (no pain) to 10 (pain as bad as you can imagine) over the past 24 hours, where higher scores represent greater pain intensity. |
| Change in clinical depressive symptom severity | Baseline, 1-week, 1-month, and 3-months after psilocybin session | The 17-item clinician administered Hamilton Rating Scale for Depression will be used to assess changes in the severity of depressive symptoms. Each item is scored by a clinician on a 3- or 5-point scale from 0 (Not present) to 4 (severe) and summed for a total score between 0 and 52. A higher total score represents greater depressive symptom severity. |
| Change in depressive symptom severity | Baseline, pre-dosing session, 5-days, 11-days, and 77-days after psilocybin session | The 7-item PROMIS-Depression self-report scale will be used as an additional indicator for changes in depression symptom severity. Items are endorsed on a 5-point scale ranging from 1 (Never) to 5 (Always). A higher total score represents greater depressive symptom severity. |
