---|---|
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:
|
- 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 ]
- 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 ]
