Evaluating fecal transplant and diet changes for ulcerative colitis treatment

Efficacy of Microbiome Manipulation Strategies Fecal Microbial Transplant or Anti-inflammatory Diet or Both With Advanced Therapies BiOlOgics and Small Molecules to Break the Therapeutic Ceiling in Active Ulcerative Colitis BOOST-UC A Multicenter Double Blind Factorial Randomized Controlled Trial

Not applicable Interventional All India Institute of Medical Sciences · NCT06906445

This study is testing if a combination of fecal transplants and dietary changes can help people with ulcerative colitis who are already on advanced treatments feel better.

What this trial studies

This clinical trial investigates the effects of fecal microbiota transplantation (FMT) combined with dietary changes on disease activity in patients with ulcerative colitis (UC) who are on advanced therapies. It employs a multicenter, randomized, factorial-design approach, where participants are assigned to one of four treatment arms involving FMT and anti-inflammatory diets. The study includes comprehensive assessments of clinical, laboratory, and endoscopic evaluations, with follow-up visits scheduled at specific intervals to monitor progress. The aim is to explore innovative treatment combinations to improve patient outcomes in managing UC.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with active ulcerative colitis who have not responded adequately to conventional therapies.

Not a fit: Patients with severe UC requiring immediate surgical intervention or those who are not treatment-naïve may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved remission rates and quality of life for patients with ulcerative colitis.

How similar studies have performed: Other studies have shown promise in using fecal microbiota transplantation for gastrointestinal conditions, suggesting potential for success in this novel approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Adult (age 18 to 75 years) patients
2. Patients with active UC (defined as mMS equal or greater than 3 with rectal bleed score equal or greater than 1 and Endoscopic Mayo score equal or greater than 2 documented within 3 months of randomization or mild symptoms with high inflammatory burden or poor prognostic features).
3. Any disease extent E1, E2 or E3. Patients with Proctitis will be limited to 25 percent of the entire pool of patients.
4. Patients with an inadequate response, loss of response, or intolerance to conventional therapies example, aminosalicylates, corticosteroids, immunosuppressants or advanced therapies including but not limited to anti TNF alpha agents, anti-integrins, anti IL 12 or IL 23 agents, anti IL 23 agents, JAK inhibitors, or S1P receptor modulators. The last administration of any such treatment must have occurred at least five half-lives prior to randomization.
5. Confirmed diagnosis of UC. The diagnosis must be confirmed by endoscopic and histologic evidence and corroborated by a histopathology report
6. Subjects who are willing and able to comply with treatment plan, laboratory tests, daily bowel movement diary call and other study procedures
7. Subjects who are willing to provide a written informed consent for FMT
8. Agree to adhere to the diet schedule
9. Infective colitis ruled out Biopsy showing crypt architecture distortion or basal plasmacytosis, OR two sigmoidoscopies, at least 7 days apart showing evidence of endoscopic activity

Exclusion Criteria:

1. Hospitalization of exacerbation of UC requiring intravenous corticosteroids
2. Patients already on biologics (anti-tumor necrosis factor inhibitors) or small molecules (tofacitinib) for equal or more than 2 weeks.
3. Clinical signs of fulminant colitis or toxic megacolon
4. Positive assay or stool culture for pathogens (ova and parasite examination, bacteria) or positive test for Clostridioides difficile toxin or CMV (histology or IHC and or tissue PCR) at screening. (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.)
5. Active or inadequately treated infections, including Mycobacterium tuberculosis.
6. Presence of IBD-unclassified, microscopic colitis, ischemic colitis, infectious colitis, or clinical findings suggestive of Crohn's Disease.
7. Patients infected with human immunodeficiency virus (HIV)
8. Patients with current or past history of malignancy.
9. Patients with current or recent history of clinically severe, progressive, or uncontrolled renal, hepatic, Hematological, gastrointestinal, metabolic, endocrine, pulmonary, cardiac, or neurological disease.
10. Pregnant females
