Study of Sc-FOS for Pouchitis Prevention

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02203955
Recruitment Status : Completed
First Posted : July 30, 2014
Last Update Posted : February 24, 2020

Laura E. Raffals, M.D, Mayo Clinic

Brief Summary:
The main objective is to compare prebiotic therapy with placebo for the prevention of pouchitis after closure of diverting ileostomy in patients with an ileal pouch anal anastomosis. This study will also characterize the effects of prebiotics on the fecal microbiota and fecal microbial metabolites and correlate these effects with the primary outcome of development of pouchitis.

Condition or disease Intervention/treatment Phase
Pouchitis Drug: Short-Chain Fructooligosaccharide Drug: Maltodextrin Phase 1

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 13 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Prevention
Official Title: Prevention of Pouchitis With Short-Chain Fructooligosaccharide Therapy, A Double-Blind, Placebo-Controlled Trial
Actual Study Start Date : August 2014
Actual Primary Completion Date : December 2017
Actual Study Completion Date : December 2018

Arm Intervention/treatment
Active Comparator: Short-Chain Fructooligosaccharide
4 chews (8.0 g scFOS) orally per day for 12 months
Drug: Short-Chain Fructooligosaccharide
4 chews (8.0 g scFOS) orally for 12 months

Placebo Comparator: Maltodextrin
4 chews (maltodextrin) daily for 12 months
Drug: Maltodextrin
4 chews (maltodextrin) daily for 12 months

Primary Outcome Measures :
  1. Mean Change in Pouchitis Disease Activity Index (PDAI) at One Year [ Time Frame: baseline, 1 year ]
    In the PDAI, an overall score is calculated from three separate six-point scales comprising of clinical symptoms, endoscopic findings and histological changes. The PDAI incorporates histological features of acute inflammation, and establishes a cut-off of seven for differentiation between 'pouchitis (≥7 points) and 'no pouchitis' (<7 points).
