Anticoagulation in Liver Fibrosis

This study has been completed.
Sponsor:
Information provided by:
Imperial College London
ClinicalTrials.gov Identifier:
NCT00180674
First received: September 13, 2005
Last updated: November 10, 2016
Last verified: September 2005
  Purpose

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.
