Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Hepatitis B, Chronic Drug: Pegylated Interferon (Peginterferon) Alfa-2a Drug: Nucleos(t)ide Analogues (NA) Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 76 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: 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
Study Start Date : January 2013
Actual Primary Completion Date : September 2013
Actual Study Completion Date : November 2014

Arm Intervention/treatment
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.

Primary Outcome Measures :
  1. 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 ]
  2. 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.

Secondary Outcome Measures :
  1. 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.

  2. Efficacy: Percentage of Participants With HBsAg Decrease >/=1 log10 IU/ml From Baseline to Week 48 [ Time Frame: Baseline, Week 48 ]
  3. 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.

  4. Efficacy: HBsAg Levels According to Interleukin 28B (IL28B) Genotypes [ Time Frame: Baseline and Week 48 ]
  5. Efficacy: HBsAg Levels According to Interferon-Inducible Protein 10 (IP-10) Serum Levels [ Time Frame: Baseline and Week 48 ]
  6. 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.
