Study 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.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Individuals aged 18-70 years.

  • Diagnosed with Major Depressive Disorder (MDD) according to DSM-V criteria.

  • Active depressive symptoms as indicated by a score > 16 on the Hamilton Depression

  • Rating Scale (HAM-D) over the preceding two weeks.

  • Female participants of childbearing potential must be using a highly effective formof contraception and willing to maintain contraceptive use throughout the studyperiod.

  • Participants must have been taking one SSRI antidepressant (e.g., citalopram,escitalopram, fluoxetine) for at least 6 weeks with at least 75% adherence.

Exclusion

Exclusion Criteria:

  • Resting blood pressure >140/90 (average of four separate measurements).

  • Risk of suicidal tendencies as indicated by a score of 3 or higher on item 3 of theHAM-D scale.

  • Use of multiple SSRIs or any antidepressant not specified in the inclusion criteria.

  • Presence of concurrent psychiatric disorders (e.g., bipolar disorder,schizophrenia).

  • Use of psychedelics or ketamine within the last 12 months.

  • Pregnancy, breastfeeding, or attempting to conceive.

  • History of substance abuse or alcohol use in the last 6 months.

  • Cardiovascular conditions (e.g., hypertension, stroke history).

Study Description

This single-masked randomized controlled trial investigates novel therapeutic interventions for Major Depressive Disorder (MDD). MDD is a leading cause of disability worldwide, with a significant proportion of patients being treatment-resistant or showing only partial response to conventional antidepressants. Emerging evidence suggests that psilocybin, a serotonergic psychedelic, has potential as a rapid-acting antidepressant.

The study will recruit 60 participants meeting DSM-V criteria for MDD, randomized into four groups:

Control group (Conventional therapy only), Psilocybin therapy group, Cognitive Behavioral Therapy (CBT) group, and Psilocybin-assisted CBT group. Participants will receive interventions over 10 weeks, with psilocybin administered in two heroic doses six weeks apart, and CBT delivered in 8-10 structured sessions. Biochemical and neurochemical markers such as CD4/CD8 ratio, TNF-α, IL-6, BDNF, and oxytocin will be measured, along with inflammatory markers (resistin and visfatin). Depression scores will be assessed using scales like HAM-D, MADRS, and BDI. EEG recordings will evaluate changes in brain activity pre- and post-intervention.

The primary objective is to assess improvements in depression symptoms, while secondary objectives include evaluating changes in immune, inflammatory, and neurochemical markers and EEG activity. Data will be analyzed using ANOVA with Tukey's post-hoc tests to determine statistical significance.
