  • Efficacy: Percent Change From Baseline in Serum Hepatitis B Surface Antigen (HBsAg) Titer at End of the Combination Treatment (Week 48) [ Time Frame: Baseline up to Week 48 ] [ Designated as safety issue: No ]
  • Efficacy: Percentage of Participants With Serum Hepatitis B Surface Antigen (HBsAg) Decrease >/= 50% From Baseline at End of the Combination Treatment (Week 48) [ Time Frame: Baseline and Week 48 ] [ Designated as safety issue: No ]
    Participants who stopped pegylated interferon (PEG-IFN) treatment during the add-on phase due to serum HBsAg loss and HBsAg seroconversion were considered as responders.
Proportion of patients with serum HBsAg decrease >/= 50% from baseline to the end of the combination treatment Pegasys plus NA (Study Week 48) [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]

  • Safety: Number of Participants With Adverse Events (AE) [ Time Frame: Baseline up to Week 48 ] [ Designated as safety issue: No ]
    An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
  • Proportion of patients with HBsAg decrease >/=1 log10 IU/ml from baseline to Week 48 [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Change in HBsAg levels [ Time Frame: from baseline to Week 96 ] [ Designated as safety issue: No ]
  • Proportion of patients with HBsAg </= 0.05 UI/ml at Week 48 [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Proportion of patients with HBsAg </= 0.05 UI/ml at Week 72 [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]
  • Proportion of patients with HBsAg </= 0.05 UI/ml at Week 96 [ Time Frame: approximately 2.5 years ] [ Designated as safety issue: No ]

A Study of Pegasys (Peginterferon Alfa-2a) Added to Nucleos(t)Ide Analogue Treatment in Participants With HBeAg-Negative Chronic Hepatitis B Genotype D Showing Stable Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) Suppression
A Phase IIb, Open Label, Single Arm, Multicenter Study to Evaluate the Effect of 48-weeks PEG-Interferon Alfa-2a (PEG-IFN) Administration on Serum HBsAg in Chronic Hepatitis B, HBeAg-Negative, Genotype D Patients on Treatment With Nucleos(t)Ide Analogues (NAs), Showing Stable HBV DNA Suppression
This open-label, single-arm, multicenter study will evaluate the efficacy and safety of adding Pegasys (peginterferon alfa-2a) to nucleos(t)ide analogue (NAs) treatment in participants with HBeAg-negative chronic hepatitis B genotype D showing stable HBV DNA suppression. After a 12-week Lead-in period on treatment with NA, participants with a HBsAg decline <0.5 log10 IU/ml will enter the Add-on period to receive Pegasys 180 mcg subcutaneously weekly for 48 weeks in addition to their current NA treatment. Follow-up will be a further 48 weeks, during which the participants will continue their NA treatment.

Hepatitis B, Chronic
  • Drug: Pegylated Interferon (Peginterferon) Alfa-2a
    Peginterferon alfa-2a 180 mcg, subcutaneously (SC) once weekly for 48 weeks.
    Other Name: Pegasys
  • Drug: Nucleos(t)ide Analogues (NA)
    Nucleos(t)ide analogues includes adefovir, entecavir, lamivudine or tenofovir.
Experimental: Pegylated Interferon (Peginterferon) Alfa-2a
Participants receiving nucleos(t)ide analogues (NA) therapy with Hepatitis B surface Antigen (HBsAg) decline less than <0.5 log 10 international unit/milliliter (IU/ml) at baseline received peginterferon alfa-2a 180 microgram (mcg), subcutaneously (SC) once weekly for 48 weeks along with their NA therapy.
