Rifaximin to Prevent Recurrent Fibrosis

Phase:
II

Prospective Randomized Double Blind Placebo Controlled Trial of Rifaximin 550mg PO Twice Daily for Three Months to Prevent Recurrent Fibrosis in Liver Transplant Recipients with Chronic Hepatitis C Virus Infection

The purpose of this study is to determine if the administration of a poorly-absorbable antibiotic (rifaximin) for the first three months after liver transplant will reduce the amount of fibrosis (or scarring of the liver) in liver transplant patients with recurrent hepatitis C virus (HCV) by lowering serum lipopolysaccharide (LPS), a protein in blood that comes from the bacteria in intestines and may cause scarring in the liver.

Approximately 60 subjects will participate in this study. Subjects will be part of the study for approximately 1 year post transplant.
