About this trial
This study is a two-group feasibility study of oral psilocybin combined with a 12-week group-based program, customized for firefighters. Trained facilitators will help create a trauma-informed space for the group (n = 6-8) to thrive and promote cognitive resilience. The topics covered throughout the 12 weeks include breath-work, mindfulness, self-compassion, embodiment, and Internal Family Systems work.
Group 1 (control): 12-week group-based program, with a breathwork day at week 10
Group 2 (intervention): 12-week group-based program, with a 10mg dose of psilocybin (PEX010) at Week 10
Assessment timepoints:
* Baseline * Mid-program (Week 6) * End of program (Week 12) * 6-month follow up

Treatments tested in this trial
Psilocybin
DrugPsilocybin in the study comes in the form of the study drug, PYEX. PYEX is a drug substance which is a partially purified fraction of the extract of Psilocybe cubensis mushroom fruiting bodies. It is a mixture of indole alkaloids, other mushroom fruiting body components and stabilization excipients. The major indole alkaloids present include psilocybin and psilocin (dephosphorylated psilocybin). PEX010 is a capsule for oral administration and is manufactured with PYEX (12.5-14.0% psilocybin), excipients, and HPMC (hydroxypropyl methyl cellulose) capsules.

Trial outcomes
Primary outcomes
Target recruitment rate
A minimum recruitment rate of 70% of our target of 36 individuals within 6 months
Retention rate
Retention rate of 90% at study completion
Adherence to schedule
Adherence to scheduled study visits at a rate of 90% or higher at study completion.
Secondary outcomes
Scores on the GAD-7 Anxiety Scale
Scores on the GAD-7 Anxiety scale will be evaluated using a two-way mixed effects ANOVA with a between factor of GROUP and a within factor of TIME to determine the effect of the psilocybin and control interventions on symptoms of anxiety in firefighters. The scale reports scores with a lowest value of 0 representing "Not at all" experiencing the symptoms of what is asked in the questions. The highest score of 3 represents "Nearly every day" experiencing the symptoms of what is asked in the questions.
