Lyophilized fecal microbiota transplant for adults with active ulcerative colitis

Official title: A Multi-centre, Randomised Controlled Trial Comparing Fecal Microbiota Transplantation to Placebo in an Expanded Ulcerative Colitis Population: a Feasibility Study (FRONTIER-UC)

Run by University of Alberta · NCT07401680 · Data updated 2026-11-12

This trial will test whether a dried (lyophilized) fecal microbiota transplant helps adults with active ulcerative colitis when added to their current treatment or started alongside a new advanced medication.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with an established diagnosis of active ulcerative colitis who can provide informed consent and attend outpatient visits are the intended participants.

Probably not a fit

Patients with severe UC requiring hospitalization, Crohn's disease or indeterminate colitis, recent intestinal infection, planned colectomy, recent abdominal surgery, or uncontrolled medical or psychiatric conditions are unlikely to be eligible or to benefit from this trial.

What this trial studies

This randomized, double-blind, placebo-controlled Phase 1 feasibility trial will enroll 85 outpatients across three Canadian centres to compare lyophilized fecal microbiota transplantation (LFMT) with placebo in people with active ulcerative colitis. Participants will be randomized to receive LFMT or placebo either as an adjunct to their existing therapy or when initiating or switching to a new advanced agent. The study uses an oral, lyophilized FMT product and focuses on safety, tolerability, and early signals of clinical benefit to determine whether a full-scale randomized controlled trial is feasible. Standard clinical and laboratory monitoring will be performed and patients with severe or complicated disease are excluded.

Why it matters

Potential benefit: If successful, LFMT could offer a new, non-antibiotic option to improve symptoms or induce remission in some people with active ulcerative colitis.

How similar studies have gone: Fecal microbiota transplantation is proven for recurrent C. difficile infection, but previous trials in ulcerative colitis have had mixed results and lyophilized oral formulations remain a relatively new approach.
