Anticoagulation in Liver Fibrosis in Patients With Hepatitis C Virus Infection

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00180674

Brief Summary:

Patients who have been treated for hepatitis C virus (HCV) infection who have failed to respond to anti-viral treatment are often concerned about their ongoing liver disease and are therefore looking for alternative treatments which might prevent fibrosis progression. This view is endorsed by patient representative groups (including Charles Gore at the HepC Trust) who have welcomed this trial protocol.

The trial will be a randomised cross over study with 15 patients in each group. Each patient will receive eight weeks of anticoagulation and eight weeks of observation.
