Evaluating Fecal Transplant and Diet Changes for Crohn's Disease

Official title: Efficacy of Microbiome Manipulation Strategies (Fecal Microbial Transplant or Crohns Disease Exclusion Diet or Both) With Advanced Therapies (BiOlOgics and Small Molecules) to Break the Therapeutic Ceiling in Active Crohns Disease (BOOST-CD): A Multicenter Double Blind Factorial Randomized Controlled Trial

Run by All India Institute of Medical Sciences · NCT06890637 · Data updated 2026-11-12

This study is testing if combining a special diet with fecal transplants can help people with active Crohn's Disease feel better while they are on other treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-75 with active Crohn's Disease who are candidates for advanced therapy and have not responded to or are intolerant to previous treatments.

Probably not a fit

Patients in remission, those with stricturing disease, or those with certain comorbidities may not benefit from this study.

What this trial studies

This multicenter, double-blind, factorial randomized controlled trial aims to assess the effectiveness of fecal microbiota transplantation (FMT) combined with a Crohn's Disease Exclusion Diet (CDED) in patients with active Crohn's Disease who are undergoing advanced therapies. Participants will be randomized into four groups to receive different combinations of FMT, sham FMT, CDED, and sham diet, alongside their ongoing advanced therapy. The study will be conducted across six clinical centers in India, with a focus on understanding how these interventions can improve disease activity and potentially break the therapeutic ceiling in Crohn's Disease management.

Why it matters

Potential benefit: If successful, this approach could provide a novel treatment option that enhances the effectiveness of existing therapies for patients with Crohn's Disease.

How similar studies have gone: While the combination of FMT and dietary interventions is a novel approach, previous studies have shown promise in using FMT for inflammatory bowel diseases, indicating potential for success.
