NCT01937728

Brief Summary

The purposes of this study are:

  1. 1.To test if 36 weeks of standard dose of ribavirin with PEGASYS® is non-inferior to standard dose of 48 weeks of ribavirin with PEGASYS® in SVR for patients with RVR and HVL
  2. 2.To test if the 72 weeks of treatment with PEGASYS® plus standard dose ribavirin is superior to 48 weeks of the same treatment for patients with HCV RNA seropositivity at week 12

  • Liver biopsy findings consistent with the diagnosis of chronic hepatitis C infection with or without compensated cirrhosis (Exception: hemophiliacs in whom biopsy is medically contra-indicated do not require biopsy.)
  • Compensated liver disease (Child-Pugh Grade A clinical classification)
  • Negative urine or blood pregnancy test (for women of childbearing potential) documented within the 24-hour period prior to the first dose of study drug
  • All fertile males and females receiving ribavirin must be using two forms of effective contraception during treatment and during the 6 months after treatment end

You may not qualify if:

  • Women with ongoing pregnancy or breast feeding
  • Therapy with any systemic anti-neoplastic or immunomodulatory treatment (including supraphysiologic doses of steroids and radiation) \*6 months prior to the first dose of study drug
  • Any investigational drug \*6 weeks prior to the first dose of study drug
  • Co-infection with active hepatitis A, hepatitis B and/or human immunodeficiency virus (HIV)
  • History or other evidence of a medical condition associated with chronic liver disease other than HCV (e.g., hemochromatosis, autoimmune hepatitis, metabolic liver disease, alcoholic liver disease, toxin exposures)
  • Signs or symptoms of hepatocellular carcinoma
  • History or other evidence of bleeding from esophageal varices or other conditions consistent with decompensated liver disease
  • Neutrophil count \<1500 cells/mm3 or platelet count \<90,000 cells/mm3 at screening
