What this trial studies

The study enrolls 30 adults with chronic spinal cord injury and diagnosed major depressive disorder, split between paraplegia and tetraplegia, and assigns participants in a stepwise design to low (5 mg), medium (10 mg), or high (25 mg) psilocybin doses. Participants complete seven psilocybin-assisted therapy visits plus follow-up visits over about 12 months, with both in-person visits at the James J. Peters VA Medical Center in the Bronx and remote check-ins. Primary outcomes track the number and severity of adverse events (including pain, muscle spasms, blood pressure changes) and tolerability of the psychedelic experience, while secondary outcomes include changes in depression severity, neuropathic pain, spasms, and quality of life. The protocol requires supervised tapering of antidepressants and uses audio/video recording and medical record release for safety monitoring.

Who should consider this trial

Good fit: Ideal candidates are adults (≥22 years) with a spinal cord injury at least one year old, a confirmed diagnosis of major depressive disorder, able to taper antidepressants under supervision, weigh at least 50 kg, and able to attend in-person visits in the Bronx and complete study procedures in English.

Not a fit: People with a history of Bipolar I disorder, recent use of psychedelics or ketamine, recent ECT, active severe substance or eating disorders, ventilator dependence, inability to give informed consent, or inability to taper antidepressants are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If safe and effective, psilocybin could offer a new treatment option to reduce depressive symptoms and improve wellbeing for people living with chronic spinal cord injury.

How similar studies have performed: Previous psilocybin trials have shown promising antidepressant effects in general populations, but people with spinal cord injury have not been previously included and safety in this group is untested.
