Because PEG-IFN therapy results in a high rate of sustained off-therapy response, patients with advanced fibrosis or cirrhosis but compensated liver disease should not be excluded from PEG-IFN treatment.
WIN-R (Weight-based dosing of pegINterferon alfa-2b and Ribavirin) was a multicenter, randomized, open-label, investigator-initiated trial involving 236 community and academic sites in the United States, comparing response to pegylated interferon (PEG-IFN) alfa-2b plus a flat or weight-based dose of ribavirin (RBV) in treatment-naive patients with chronic hepatitis C and compensated liver disease.
