ClinicalTrials.gov Identifier:	NCT00189033

Purpose

The purpose of this study is to assess the role of dietary fibre in Irritable Bowel Syndrome (IBS) treatment, in particular the role of increasing the content of soluble or insoluble fibres in the daily diet. The primary objective is to compare soluble (psyllium) and insoluble (bran) to placebo, administered over 12 weeks in patients with ‘probable’ or ‘definite’ Irritable Bowel Syndrome. The primary efficacy parameter is the responder rate based on weekly assessment of adequate relief of IBS symptoms. Secondary efficacy parameters include changes in IBS related symptoms (abdominal pain, bowel habits) and quality of life.
