PTSD Clinical Trial - Evaluation of Psilocybin-assisted Psychotherapy

Status Not yet recruiting

Clinical Trial Summary

Post-Traumatic Stress Disorder (PTSD) is a mental health condition that occurs as a result of a traumatic experience. Symptoms include feeling anxious, flashbacks, nightmares and difficulty sleeping. Several studies indicate that psilocybin-assisted psychotherapy (PaP) may be an effective treatment for a number of mental health conditions. This has led to PaP being designated as a "breakthrough treatment" by the FDA in the US. Despite indications that PaP may hold benefits in treating individuals with posttraumatic stress disorder (PTSD), this remains to be investigated. As such, the present study aims to examine the acceptability, feasibility, safety, and efficacy of PaP (psilocybin administered with psychotherapy) in treating PTSD in military veterans.

Clinical Trial Description

Recent studies have shown that Psilocybin-Assisted Psychotherapy (PaP) for individuals with treatment-resistant depression can result in outcomes that exceed routine psychotherapy. Psilocybin may have a catalytic effect on the psychotherapeutic process, enhancing introspection and interoception. PaP may similarly benefit the treatment of posttraumatic stress disorder (PTSD). Research indicates high treatment drop-out rates (approximately 30%) among PTSD patients, and moderate remission rates (approximately 44%) 40 months after completing treatment. Furthermore, some veterans with PTSD have poorer treatment responses than members of the general public. This suggests that alternative treatment approaches may be required to support veterans who do not benefit from standard evidence-based approaches. This study aims to explore the acceptability, feasibility, safety and efficacy of PaP for veterans with PTSD. A total of eight military veterans will be recruited. The study involves two non-directive preparatory sessions, two dosing sessions of psilocybin, followed by 12 sessions of Cognitive Processing Therapy. It is hypothesised that PaP will result in a significant reduction in PTSD symptoms, as indicated by PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders (DSM-5; PCL-5) scores from baseline to one-month follow-up. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
