What is the purpose of this trial?

This trial examines how psilocybin, a compound in magic mushrooms, can aid first responders, such as firefighters, in managing mental health conditions like PTSD, depression, or anxiety. Participants will engage in a 12-week program emphasizing wellness techniques, including mindfulness and breathwork. One group will receive a psilocybin dose in week 10, while the other will participate in a dedicated breathwork day. Firefighters diagnosed with a mental health condition who can attend both in-person and remote sessions may be suitable for this study. The researchers aim to determine if this approach can enhance mental resilience and overall well-being. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to be among the first to experience this innovative approach.

Do I need to stop taking my current medications for the trial?

Participants must have a stable dose of their current medications for the last three months and should not anticipate changes during the study. However, they must refrain from taking certain nonprescription medications, nutritional supplements, or herbal supplements for one week before the drug sessions, unless approved by the study Investigator.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that psilocybin, the treatment under study, is generally safe for humans. In a recent study on psilocybin for post-traumatic stress disorder, participants who took a single 25 mg dose experienced no serious side effects. Most side effects were mild and short-lived, such as nausea, anxiety, and headaches. Another study found that 77% of participants experienced side effects like headaches, nausea, and dizziness, but these were not severe.

It is important to note that psilocybin can sometimes cause "bad trips" or panic reactions, where individuals feel anxious or scared. However, these effects are usually temporary. The fact that psilocybin is being studied in a Phase 1/2 trial indicates it has demonstrated some level of safety in earlier tests. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatment?

Most treatments for stress-related conditions in first responders, such as therapy and medication, can take weeks or even months to show effectiveness. However, psilocybin offers a novel approach because it involves a psychedelic compound that may rapidly promote cognitive resilience and emotional healing. Unlike traditional treatments, psilocybin acts on serotonin receptors in the brain, potentially leading to profound shifts in perception and mood in a matter of hours. Researchers are excited because this could mean faster relief from stress and trauma, offering a transformative experience that complements traditional therapeutic practices.

What evidence suggests that psilocybin-assisted therapy could be effective for first responders?

Research has shown that psilocybin can significantly alleviate PTSD (post-traumatic stress disorder) symptoms. Studies have found that a single dose of psilocybin can lead to noticeable improvements in individuals with PTSD, with benefits lasting up to 12 weeks. In this trial, participants in the active group will receive 10mg of psilocybin during Week 10 of the program. Psilocybin reduces activity in the amygdala, the brain region responsible for fear and emotions. This reduction can help individuals manage their emotions better and may decrease intense fear reactions. Early findings also suggest that psilocybin is generally safe, with no serious side effects reported. These results indicate that psilocybin could be a promising treatment for conditions related to trauma. ^{3 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Psilocybin

Trial Overview The study compares two groups: one receives standard group therapy with breathwork, while the other gets the same plus a single dose of psilocybin. The goal is to see if psilocybin can enhance the effectiveness of group therapy for first responders.

How Is the Trial Designed?

Group I: Active Group Experimental Treatment 1 Intervention

All participants will undergo a 12-week, group-based program (one session per week, for 12 weeks). The first group session, as well as the Week 10 session will occur in-person. The remainder of the sessions will occur remotely. Each week, trained facilitators will help create a trauma-informed safe space for the group to thrive and promote cognitive resilience. The topics covered throughout the 12-week program include breath-work, mindfulness, self-compassion, embodiment, and Internal Family Systems work. During Week 10, participants will be provided with either psilocybin (active group) or complete a breathwork day (control group). For participants randomized to the active group, they will receive 10mg of psilocybin on Week 10. A clinician certified and trained in the therapeutic use of psilocybin will be on site for participants in the psilocybin group.
