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.
|
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.

- 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 ]
- 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 ]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.
- Efficacy: Change From Baseline in Serum Hepatitis B Surface Antigen (HBsAg) Titer at Week 24, 72 and 96 [ Time Frame: Baseline, Week 24, 72 and 96 ]Change is calculated by HBsAg titer at baseline - HBsAg titer at week of assessments.
- Efficacy: Percentage of Participants With HBsAg Decrease >/=1 log10 IU/ml From Baseline to Week 48 [ Time Frame: Baseline, Week 48 ]
- Efficacy: Number of Participants With Serum HBsAg Loss at Week 12 That Persisted up to Week 96 [ Time Frame: Week 12 up to Week 96 ]HBsAg loss is defined as HBsAg less than or equal to (</=) 0.05 IU/ml.
- Efficacy: HBsAg Levels According to Interleukin 28B (IL28B) Genotypes [ Time Frame: Baseline and Week 48 ]
- Efficacy: HBsAg Levels According to Interferon-Inducible Protein 10 (IP-10) Serum Levels [ Time Frame: Baseline and Week 48 ]
- Safety: Percentage of Participants With Adverse Events (AE) [ Time Frame: Baseline up to Week 48 ]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.
