Clinical Trial Summary

To compare the safety and efficacy of concomitant LFMT versus placebo in UC patients who are starting vedolizumab or ustekinumab.

Description:

This is dual-center, randomized, double-blind, placebo-controlled pilot trial for UC patients with active disease who are being initiated on treatment with vedolizumab or ustekinumab.

The study will recruit 40 outpatients at 2 Canadian healthcare centres at the University of Alberta Hospital (University of Alberta), and the Hamilton Health Sciences (McMaster University).
