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.
