Testing the Drug Obeticholic Acid for Familial Adenomatous Polyposis

About the Study

This study is looking at whether obeticholic acid (OCA) is safe and has a beneficial effect on the number of in the small bowel and colon in people with familial adenomatous polyposis (FAP). OCA is a drug similar to a bile acid the body's liver makes. Researchers believe OCA may help keeping cancer from developing. OCA is already approved to treat a type of liver disease. There have been studies showing that OCA decreases inflammation and fibrosis. However, it is not yet known whether OCA works on reducing the number of in patients with FAP.

What the Study Involves

Participants will be divided into two groups:

  • Group 1 will receive OCA for 6 months
  • Group 2 will receive a for 6 months

All participants will undergo GI endoscopy with biopsy and collection of blood samples at screening and on study.

After completion of the study treatment, patients are followed within 14-21 days.
