Brief Summary
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.
