LFMT vs Placebo in New Biologic Start for Ulcerative Colitis

Official title

A Dual-center, Double Blind, Randomized Placebo-controlled Pilot Trial of Concomitant Lyophilized Fecal Microbiota Transplantation (LFMT) and Biologic Therapy (Vedolizumab or Ustekinumab) for the Induction of Remission in Ulcerative Colitis (UC)

Overview

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

Detailed 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 University of Manitoba.

Interventions

• Drug Lyophilized fecal microbiota (LFMT)
  vedolizumab or ustekinumab + FMT vs placebo
• Other Placebo
  Placebo

Primary outcome measures

• Proportion of participants with serious adverse events (SAEs) of interest up to week 8 in each group (ie vedolizumab with or without LFMT, ustekinumab with or without LFMT). [Time frame: 24 weeks]

Secondary outcome measures (9)

• Proportion of participants in each group with adverse events during the study up to week 24, including nausea, vomiting, abdominal pain, worsening diarrhea, constipation or fevers [Time frame: 24 weeks]
• Proportion of participants who achieve clinical remission, defined as total Mayo score ≤ 2 with no individual subscore > 1, at week 8 and 24 in each group. [Time frame: 24 weeks]
• Proportion of participants who achieve clinical response [Time frame: 24 weeks]
• Proportion of participants who achieve symptom remission, defined as partial Mayo score < 2 with no individual subscore > 1, at week 8 and 24 in each group [Time frame: 24 weeks]
• Proportion of participants who achieve symptom response, defined as reduction in partial Mayo score ≥ 2 points from baseline and ≥ 30% from baseline and decrease in rectal bleeding score of ≥ 1point from baseline, at week 8 and 24 in each group [Time frame: 24 weeks]
• Proportion of participants who achieve endoscopic improvement, defined as Mayo endoscopic subscore ≤1, at week 8 and 24 in each group [Time frame: 24 weeks]
• Changes in partial Mayo score over time up to week 24 relative to baseline in each group [Time frame: 24 weeks]
• Changes in quality of life, assessed by short IBD Questionnaire (sIBDQ), and work productivity, assessed by Work Productivity and Activity Impairment Questionnaire (WPAIQ), at week 8 and 24 relative to baseline in each group [Time frame: 24 weeks]
• Changes in inflammatory markers (serum c-reactive protein (CRP) and fecal calprotectin) over time up to week 24 in each group [Time frame: 24 weeks]
