A Study to Evaluate the Effect of Fecal Transplant and Dietary Changes on Disease Activity in Patients With Crohn Disease on Advanced Therapies

Inclusion Criteria: 1. Patients with active Crohn disease in whom FMT is feasible 2. Active Crohn's disease who are candidates for advanced therapy (steroid refractory, Immunomodulator intolerant or refractory and moderately severe disease at the time of inclusion) or patients who have an intolerance to or have lost response to advanced therapies must have had their last treatment at least five half-lives prior randomization. 3. Aged between 18-75 years 4. CDAI greater than 150 and/or SES-CD equal or greater than 6 (or equal or greater than 4 if isolated ileal disease) Exclusion Criteria: 1. Patients in remission (CDAI less than 150) 2. Stricturing disease (non-passable stricture) in whom FMT is not feasible 3. Fistulising phenotype or Perianal fistula or abscess 4. Isolated L4 disease 5. Active TB or Sepsis 6. Pregnant or lactating women 7. Patients with co-morbidities like CAD/CLD/CKD 8. Previous surgery for CD 9. Declining consent or not willing for FMT or diet advice 10. Patients with current or recent history of clinically severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, metabolic, endocrine, pulmonary, cardiac, or neurological disease. 11. Positive assay or stool culture for pathogens (ova and parasite examination, bacteria) or positive test for Clostridioides difficile toxin at screening# 12. Patients infected with human immunodeficiency virus (HIV) #The patients with positive assay will be treated appropriately and tests will be repeated. Those with negative assay and persistent activity will be included in the study
