  Purpose

This study will evaluate the efficacy and safety of PEGASYS (peginterferon alfa-2a) in patients with HBeAg positive chronic hepatitis B. Patients will be stratified into group A (treatment naïve patients) or B (YMDD mutant patients). All patients will receive PEGASYS 180 micrograms subcutaneously once weekly for 48 weeks, followed by 24 weeks of treatment-free follow up.

Primary Outcome Measures:
  • Percentage of patients with hepatitis B virus DNA <100,000 copies/mL [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with hepatitis B virus HBeAg loss rate [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of patients with alanine aminotransferase (ALT) normalization [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with hepatitis B virus (HBV) DNA below limit of detection [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with a combined response of HBeAg seroconversion, loss of HBeAg, and alanine aminotransferase normalization [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with HBeAg seroconversion [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with loss of HBsAg [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with loss of HBsAg and presence of anti-HBs [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
