Brief Summary:
The outcome of treatment of chronic hepatitis B is determined by viral and host interaction, thus the combination therapy of immunomodulator (PEG-IFN) and potent antiviral drug (entecavir) should improve the response rate. In addition, the simultaneous assessment of viral and host genetic factors associated with SVR may help to identify predictors of treatment outcomes, which will in turn significant reduce the cost/effect of therapy

Arm Intervention/treatment
Active Comparator: drug combination Drug: PEG-IFN and entecavir
The patients will be randomized in approximately 1:1 ratio into one of 2 treatment regimens; to receive PEG-IFN alpha-2b (1.5 microgram/kg/week) plus entecavir (0.5 mg/day) or PEG-IFN alpha-2b (1.5 microgram/kg/week) alone for 48 weeks by using pre-generated randomization schedule.
Other Names:
  • pegintron
  • baraclude

Primary Outcome Measures :
  1. To determine whether a combination of PEG-IFN and entecavir improves the rate of sustained response and HBsAg clearance in patients with HBeAg-negative chronic hepatitis B [ Time Frame: 24 weeks post treatment ]

Secondary Outcome Measures :
  1. To determine host factors and viral factors associated with response to PEG-IFN alone or PEG-IFN plus entecavir treatment [ Time Frame: 24 weeks post treatment ]
