This multicenter, prospective, observational study will evaluate the use in clinical practice and the efficacy and safety of Pegasys (peginterferon alfa-2a) in Chinese participants with HBeAg negative chronic hepatitis B. Participants receiving Pegasys according to the local label will be followed for the duration of their treatment and for one year after cessation of treatment.

Primary Outcome Measures:
  • Incidence of sustained suppression of HBV DNA <2000 IU/mL one year after treatment cessation [ Time Frame: approximately 4 years ]

Secondary Outcome Measures:
  • Incidence of suppression of HBV DNA <2000 IU/mL at the end of treatment and 6 months post-treatment [ Time Frame: approximately 4 years ]
  • Incidence of HBV DNA undetectable (<400 IU/mL) at the end of treatment and 1 year post-treatment [ Time Frame: approximately 4 years ]
  • Incidence of HBsAg loss/seroconversion [ Time Frame: approximately 4 years ]
  • Incidence of normalization of serum ALT levels [ Time Frame: approximately 4 years ]
  • Dosage/schedule of Pegasys treatment in real-life clinical setting [ Time Frame: approximately 4 years ]
  • Clinical/demographic patient characteristics at initiation of treatment [ Time Frame: approximately 4 years ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 4 years ]
