This observational study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) in patients with chronic hepatitis B who have failed antiviral treatment with nucleoside (nucleotide) analogues. Data will be collected from patients treated according to the current Summary of Product Characteristics and local standard of care and regulations during 48 weeks of treatment and 24 weeks of follow-up.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Efficacy: HBsAg seroclearance/seroconversion rate at the end of Week 72 (48 weeks of treatment and 24 weeks of follow-up) [ Time Frame: approximately 2.5 years ]

Secondary Outcome Measures:
  • HBs levels in correlation with treatment outcome [ Time Frame: approximately 2.5 years ]
  • For HBeAg positive patients: Proportion of patients with HBeAg loss and presence of anti HBe (HBeAg seroconversion) at the end of Week 72 (48 weeks of treatment and 24 weeks of follow-up) [ Time Frame: approximately 2.5 years ]
  • For HBeAg negative patients: Proportion of patients with HBV DNA </= 2000 IU/ml and ALT normalization [ Time Frame: approximately 2.5 years ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 2.5 years ]
