  • Percentage of Participants With Hepatitis B Virus DNA (HBV-DNA) <100,000 Copies/mL [ Time Frame: Week 72 ] [ Designated as safety issue: No ]
    Participants who had HBV-DNA levels below 100,000 copies per milliliter (mL) at the end of follow-up (EOF) period (24 weeks after the end of treatment) were classified as responders.
  • Percentage of Participants With Hepatitis B Virus e Antigen (HBeAg) Loss [ Time Frame: Week 72 ] [ Designated as safety issue: No ]
    Participants with loss of HBeAg at the EOF period (24 weeks after the end of treatment) were classified as responders.
  • Percentage of patients with hepatitis B virus DNA <100,000 copies/mL [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with hepatitis B virus HBeAg loss rate [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]

  • Percentage of Participants With Alanine Aminotransferase (ALT) Normalization [ Time Frame: Week 48 and Week 72 ] [ Designated as safety issue: No ]
    Participants with ALT less than the ULN (upper limit of normal) at end of treatment (EOT) and EOF period were responders.
  • Percentage of Participants With HBV-DNA Below the Limit of Detection [ Time Frame: Week 48 and Week 72 ] [ Designated as safety issue: No ]
    Participants with HBV-DNA below the limit of detection i.e. <174 copies/mL at EOT and EOF period were responders.
  • Percentage of Participants With a Combined Response [ Time Frame: Week 48 and Week 72 ] [ Designated as safety issue: No ]
    A responder with Combined Response was a participant with HBV-DNA<100,000 copies/mL, HBeAg seroconversion (i.e. loss of HBeAg and presence of anti-HBe) and ALT normalization at EOT and EOF period.
  • Percentage of Participants With HBeAg Seroconversion [ Time Frame: Week 48 and Week 72 ] [ Designated as safety issue: No ]
    A responder was a participant with loss of HBeAg and presence of anti-HBe at EOT and EOF period.
  • Percentage of Participants With Loss of Hepatitis B Surface Antigen (HBsAg) [ Time Frame: Week 48 and Week 72 ] [ Designated as safety issue: No ]
    A responder was a participant who were analysed with loss of HBsAg at EOT and EOF period.
  • Percentage of Participants With HBsAg Seroconversion [ Time Frame: Week 48 and Week 72 ] [ Designated as safety issue: No ]
    A responder was a participant with loss of HBsAg and presence of anti-HBs at EOT and EOF period.
  • Number of Participants With Adverse Events (AE) [ Time Frame: Up to Week 72 ] [ Designated as safety issue: No ]
    An adverse event was defined as any untoward medical occurrence that occurred during the course of the trial after study treatment had started. An adverse event was therefore any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. A SAE is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.
  • Percentage of patients with alanine aminotransferase (ALT) normalization [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with hepatitis B virus (HBV) DNA below limit of detection [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with a combined response of HBeAg seroconversion, loss of HBeAg, and alanine aminotransferase normalization [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with HBeAg seroconversion [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with loss of HBsAg [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Percentage of patients with loss of HBsAg and presence of anti-HBs [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: 72 weeks ] [ Designated as safety issue: No ]

An Open Label Phase IV Multicenter Study for Efficacy and Safety of Peginterferon Alfa-2a (40KD) (PEGASYS®) in Patients With HBeAg Positive Chronic Hepatitis B
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.
