This multicenter, prospective, observational study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) in routine clinical practice in patients with HBeAg-positive or HBeAg-negative chronic hepatitis B. Eligible patients receiving treatment with Pegasys according to standard of care and the summary od product characteristics/local labelling will be followed for the duration of treatment and up to 2 years of follow-up.

Primary Outcome Measures:
  • Change in HBsAg (IU/ml) levels during therapy (up to 48 weeks) and follow-up [ Time Frame: from baseline to up to approximately 3 years ] [ Designated as safety issue: No ]
  • Change in HBV DNA (IU/ml) during therapy (up to 48 weeks) and follow-up [ Time Frame: from baseline to up to approximately 3 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of patients with sustained immune control (sustained HBV DNA <2000 IU/ml in HBeAg-negative and HBeAg-positive patients or HBeAg seroconversion in HBeAg-positive patients) [ Time Frame: approximately 4 years ] [ Designated as safety issue: No ]
  • Percentage of patients with normalisation of serum alanine transaminase (ALT) levels [ Time Frame: approximately 4 years ] [ Designated as safety issue: No ]
  • Percentage of patients with HBsAg clearance/seroconversion [ Time Frame: approximately 4 years ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 4 years ] [ Designated as safety issue: No ]
