Is this trial a fit for you?

Likely a good fit

Ideal candidates are treatment-naïve adults aged 18-75 with mild to moderate active ulcerative colitis.

Probably not a fit

Patients with severe ulcerative colitis or other forms of colitis may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effects of fecal microbiota transplantation (FMT) combined with an anti-inflammatory diet on patients with newly diagnosed active ulcerative colitis (UC). It employs a multi-center, double-blind, 2x2 factorial design to randomize treatment-naïve patients into four groups, each receiving different combinations of FMT, dietary interventions, and standard medication (5-ASA). The study aims to assess the impact of these interventions on disease activity and gut microbiota composition. Participants will receive FMT through colonoscopy and follow a specific dietary regimen over several weeks.

Why it matters

Potential benefit: If successful, this approach could provide a novel and effective treatment option for patients with ulcerative colitis, potentially improving their quality of life.

How similar studies have gone: Other studies have shown promising results with fecal microbiota transplantation for various gastrointestinal conditions, suggesting potential success for this approach in ulcerative colitis.
