Brief Summary
The main goal of this study is to determine if psilocybin is safe for use in people with SCI. The study will measure how people with SCI respond to three psilocybin doses: low (5mg), medium (10mg), and high (25mg). The main question the study aims to answer is: does psilocybin increase the number and severity of adverse (bad) events reported by people with SCI? These may include pain, muscle spasms, symptoms of depression, and symptoms of low or high blood pressure. The investigators will also measure how well people with SCI tolerate the psychedelic experience, and compare responses between the low (5mg), medium (10mg), and high (25mg) doses. Participants will:
- Agree to be enrolled in the study for up to 13 months.
- Agree to complete the seven (7) visits that are included in the psilocybin-assisted therapy.
- Agree to complete follow-up study visits, including in-person visits to the James J Peters VA Medical Center, located in the Bronx, New York and remote visits.
- Agree to keep a log of how they are feeling and any change in the frequency or severity of adverse events.

Outcome Measures
Primary Outcomes (1)
Number of Participants with Treatment-Related Adverse Events as Assessed by the Adverse Events Log.
The Adverse Events Log will be captured by the research team at screening, before and after medication taper (if needed), weekly during the taper, at each of the three preparatory and three integration sessions, at 44 days post dose, and at all remote and in-person follow-up visits; 16 assessments in total.
Screening through study completion, an average of 13 months.
Secondary Outcomes (2)
Clinician rated change from baseline (V1) in the Montgomery-Asberg Depression Rating Scale (MADRS) score at 44(+/-7) days post psilocybin dose (V9).
Baseline to 44 days post psilocybin.
Self reported change in depression severity score on the Beck Depression Inventory (BDI-II) from baseline (V1) to 44(+/-7) days post psilocybin (V9).
Baseline to 44 days post psilocybin.
Other Outcomes (2)
Change in self-reported levels of pain interference in daily life, overall mood, and sleep quality from baseline (V1) to 7 days post psilocybin (V7) using the International Spinal Cord Injury Pain Basic Data Set (iSCI-PBD).
Baseline to 7 days post psilocybin.
Self-reported change in frequency and severity of spasms using the Penn Spasm Frequency Scale (PSFS) .
Baseline to 7 days post psilocybin.
