Colesevelam for the Treatment of Bile Acid Malabsorption in Patients With Crohn's Disease (COBAM)
April 17, 2013 updated by: Florian Beigel
The purpose of this study is to assess the efficacy of cholestagel to reduce the frequency of soft and liquid stools per day in patients with CD in clinical remission with symptoms of BAM and to assess the improvement in stool consistency and quality of life in these patients and to assess the safety of cholestagel.
