Study Overview

Brief Summary

Dysbiosis can be rectified by several methods: antibiotics, prebiotics, probiotics, dietary modulation, and fecal microbiota transplantation. There has been limited success with the isolated use of antibiotics and pre/probiotics in the treatment of IBD. Among the measures of dietary manipulation, the use of exclusive enteral nutrition (EEN) has shown superior, or at least equivalent, efficacy compared with steroids in pediatric CD. Although the results in adults are not as encouraging, recent cohort studies in patients with complicated CD have shown good success rates. Definite exclusion diets that exclude pro-inflammatory dietary constituents have also been tested with good clinical efficacy in patients with CD, who even failed treatment with anti-TNF agents. Various dietary approaches, inclusive of exclusive enteral nutrition, partial enteral nutrition, and Crohn's disease exclusion diet have been reported to be of benefit and are associated with changes in gut microbiome. Fecal microbiota transplantation (FMT) defined as the infusion of fecal suspension from a healthy individual into the gastrointestinal tract of an individual with GI disease carries a diverse population of microbiota and their metabolites and has been tested with varying efficacy in IBD. In general, FMT has shown good success rates in randomized control trials in patients with UC who failed conventional agents. Although limited small RCTs exist in CD, cohort studies have also shown good success rates. Therefore, the use of FMT in addition to standard medical therapy, is a concept that has not been previously explored and forms the basis for the present study. Therefore, a well-powered RCT is required to resolve the role of FMT in CD. In this study, patients will be recruited in four arms. Group A includes FMT+CDED+SMT, in Group B FMT+SMT+SHAM DIET, in Group C Sham FMT+CDED+SMT, in Group D Sham FMT+ Sham Diet+ SMT given. 168 patients will be recruited across 6 centers for around 3 years. Follow-up of the patient will be done at 0,2,6 and 10 weeks and 8 weekly up to 48 weeks.

Detailed Description

This study is a multi-center, double-blind, factorial randomized controlled trial designed to evaluate the efficacy of microbiome manipulation strategies using fecal microbiota transplantation (FMT), Crohn's Disease Exclusion Diet (CDED), or their combination in treatment-naïve patients with mild to moderate active Crohn's Disease (CD).

Study Setting

The trial is conducted at six FMT centers across India, with one additional center dedicated to microbiome analysis:

AIIMS, New Delhi, India Dayanand Medical College, Ludhiana, India PGIMER, Chandigarh, India Lisie Hospital, Kochi, India IMS, BHU, Varanasi, India Sion Hospital, Mumbai, India IIIT-Delhi, India(for microbiome analysis)
