Primary Outcome Measures:
  • Primary efficacy assessment is the serological conversion rate of HBeAg at week. 48 [ Time Frame: 48 weeks ]

Secondary Outcome Measures:
  • Serological response [ Time Frame: 96 weeks ]
    Serological response at every observation time: serological conversion rate of HBeAg, negative conversion rate of HBeAg, and change of HBeAg.

  • Virological response [ Time Frame: 96 weeks ]
    Virological response at every observation time: the proportion of patients with serum HBV DNA level reduction to undetectable level, decreased amount of serum HBV DNA compared with the baseline value, and HBV DNA load decrease 2 log scales or HBV DNA level <1.72×104 IU/ml.

  • Biochemistry response [ Time Frame: 96 weeks ]
    Biochemistry response at every observation time, mean the ALT level reduce to normal.

  • Histological response [ Time Frame: 72 weeks ]
    Histological response at week 72, mean histological score limited reduce 2 (reduced score 2-5), and no fiber deterioration compare with before treatment.
