  • Be hepatitis C treatment-naïve patients.
  • Patients should have been assessed at entry and their METAVIR score of fibrosis determined as F2, F3 or F4.

    Arm Description

    All patients will receive peginterferon alfa-2b 1.5 ug/kg administered subcutaneously (SC) once weekly in combination with ribavirin (800-1200 mg/day) administered orally (PO) for a minimum period of 12 weeks. Patients who have responded to therapy at Treatment Week 12 (ie, who are Early Responders defined by HCV-RNA[-] at Treatment Week 12) will continue the combined treatment for a total of 48 weeks and will complete 24 weeks of follow up to determine the Sustained Viral Response (SVR).

Patients who have a slow response to therapy at Treatment Week 12 (ie, Slow Responders who are not HCV-RNA[-] at Treatment Week 12 but decrease >=2 log) will continue the combined treatment for a total of 72 weeks and will complete 24 weeks of follow up to determine the Sustained Viral Response (SVR).

    5. Study Description

    Brief Summary
    This study aims to evaluate the efficacy and safety of peginterferon alfa-2b plus weight-based ribavirin as initial treatment in chronic hepatitis C virus (HCV) genotype 1 patients. All patients will receive peginterferon alfa-2b plus oral ribavirin for 12 weeks. At the end of this period, quantitative PCR will be used to determine the Early Viral Response (EVR) at this point of treatment. Total treatment duration will be 48 weeks for Early Responders, 72 weeks for Slow Responders, and 12 weeks for Nonresponders.
