Effect of Psilocybin and Structured Integrated Reframing Therapy on Gut-Brain Axis Biomarkers and Depression in Major Depressive Disorder
Effect of Psilocybin and Structured Integrated Reframing Therapy on Gut-Brain Axis Biomarkers and Depression in Trauma-Related Major Depressive Disorder: Randomized Controlled Trial
Source: ClinicalTrials.gov · Last updated 14 Jul 2026
Brief summary (registry, in English)
Trauma-related Major Depressive Disorder (MDD) is frequently associated with poor response to conventional antidepressants, persistent psychological distress, and alterations in gut-brain axis function. Existing assessment tools primarily diagnose depression or PTSD but provide limited guidance for integrated clinical management. This study aims to develop and validate the Trauma Anxiety Depression Emotion (TADE) management tool while simultaneously evaluating the effectiveness of psilocybin-assisted Structured Integrated Reframing Therapy (SIRT) in improving clinical and biological outcomes. This prospective, four-arm randomized controlled trial will compare conventional therapy, psilocybin therapy, SIRT, and psilocybin-assisted SIRT. Participants will undergo assessment using the newly developed TADE tool together with established psychometric scales including HAM-D, PCL-5, and GAD-7. Biological outcomes will include serum gut-brain axis and inflammatory biomarkers, including Short-Chain Fatty Acids (SCFAs), Interleukin-6 (IL-6), Interleukin-10 (IL-10), Zonulin, Occludin, and Glial Cell Line-Derived Neurotrophic Factor (GDNF). Assessments will be performed at baseline, during treatment, and at 12-week follow-up. The study aims to determine whether combining psilocybin with SIRT provides superior clinical improvement and favorable biological changes compared with either intervention alone while establishing the validity and clinical utility of the TADE management tool.
