Stopped: Difficult to recruit severely affected patients with fecal incontinence
Accidental bowel leakage (fecal incontinence) increases in people who have diarrhea and sensations of urgency to have a bowel movement. Drugs such as loperamide (Imodium) that reduce diarrhea improve accidental bowel leakage, but loperamide has disadvantages: it is difficult to find a dose that does not cause constipation, and it does not reduce urge sensations. Eluxadoline is a new drug that is effective for reducing diarrhea, abdominal pain, and urgency in patients with irritable bowel syndrome, and it may be less likely than loperamide to cause severe constipation. Therefore, eluxadoline may help patients manage accidental bowel leakage caused by diarrhea. The chemical name for ViberziĀ® is eluxadoline. The primary aims of this study are to find out if eluxadoline at a dose of 100 mg orally twice a day will reduce the average number of days the patient has accidental bowel leakage, and to see if the rate of accidental bowel leakage increases when the patient stops taking eluxadoline. Additional goals are to find out if eluxadoline decreases diarrhea and urge sensations. This is a small (pilot) study to show whether eluxadoline is an effective way of treating accidental bowel leakage. If the study shows this, a larger study will be needed. There are three phases to this 12-week study: (1) A two-week run-in period to see if the patient meets the inclusion criteria. (2) Two months for treatment including one month on eluxadoline and one on placebo (sugar pills) twice a day. (3) A two-week follow-up to see what happens when you stop taking eluxadoline. To participate in the study, patients should be aged 18 or older. Patients with inflammatory bowel disease, anal fissures, or congenital malformations will be excluded. The primary outcome is the average number of days per week with any solid or liquid bowel accidents. Additional information includes: (1) Number of days per week the patient takes loperamide, (2) days per week with loose or watery stools, (3) days per week with moderate to strong urge sensations, and (4) questionnaires to measure the severity of accidental bowel leakage, quality of life, anxiety, and depression. There will be up to 38 patients in the study.
