Summary

This randomized controlled clinical trial evaluates the effectiveness of psilocybin and psilocybin-assisted cognitive behavioral therapy (CBT) in the management of Major Depressive Disorder (MDD). The study aims to compare the effects of psilocybin-only therapy, CBT, and psilocybin-assisted CBT on depression symptoms, neurochemical markers, inflammatory markers, and neuroplasticity in individuals with MDD. Participants will continue their routine depression medications and will be assessed for changes in depression scores, biochemical markers, and brain activity patterns using validated tools and tests.

Conditions

Interventions

DRUG

Psilocybin

Psilocybin is a naturally occurring serotonergic psychedelic compound found in Psilocybe mushrooms. It is metabolized in the body into its active form, psilocin, which has a high affinity for serotonin 5-HT2A receptors. This enables psilocin to bypass the default serotonin pathway, producing antidepressant effects. For this study: Psilocybin will be administered orally in a dose of 5-6 grams per session. Each participant in the Psilocybin and Psilocybin-assisted CBT arms will receive two sessions spaced six weeks apart. The therapy will be conducted in a controlled hospital setting with medical monitoring during the session to ensure safety until the hallucination phase subsides. Psilocybin will be added to routine antidepressant medication.

BEHAVIORAL

Cognitive Behavioral Therapy (CBT)

Cognitive Behavioral Therapy (CBT) is a structured, time-limited psychotherapy aimed at alleviating symptoms of depression. It involves addressing negative thoughts and behavioral patterns through the following steps: Identifying troubling life situations. Recognizing thoughts, emotions, and beliefs about those situations. Identifying negative or inaccurate thinking patterns. Restructuring those thoughts into positive and realistic perspectives. In this study: CBT will consist of 8-10 structured sessions, each lasting approximately 90 minutes. Participants will attend therapy sessions twice weekly over a six-week period. The intervention will be delivered by trained psychotherapists in a controlled hospital setting. Routine antidepressant medications will be continued alongside CBT.
