Study 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.

What researchers measure

Primary outcomes

  1. Mean Change in Pouchitis Disease Activity Index (PDAI) at One 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).

    Time frame: baseline, 1 year

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 24, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
