Brief Summary
Primary objective: Compare Pegasys RGT overall response rate (i.e., HBeAg seroconversion rate) with Pegasys mono historical response rate at week 72 (48 week treatment with 24 week follow up) Secondary objective :
- The changes of HBsAg titer
- The rate of combined HBeAg seroconversion and HBV DNA \< 300 copies/mL
- The rate of serum HBV DNA \< 300 copies/mL ⅳ. The rate of ALT normalization
- The rate of HBsAg loss ⅵ. The rate of serum HBV DNA \< 10,000 copies/mL

Outcome Measures
Primary Outcomes (1)
HBeAg seroconversion
24 weeks post treatment follow up
Secondary Outcomes (1)
The changes of HBsAg titer
baseline and 24weeks post treatment follow up
Study Arms (3)
HBsAg quantification>20,000 IU/ml
SHAM COMPARATORstop peginterferon alfa 2a if patients reach HBsAg quantification\>20,000 Iu/ml at 12w
HBsAg<=1500IU/ml
SHAM COMPARATORextend peginterferon alfa 2a until 48weeks
HBsAg >1500 <=20,000 IU/ML
SHAM COMPARATORadd Entecavir for 12w with peginterferon alfa 2a then, extend peginterferon alfa 2a until 48w

Eligibility Criteria
You may qualify if:
- Age ≥ 18 years
- Positive HBsAg for more than 6 months, positive HBeAg, detectable HBV DNA(patients must have \> 100,000 copies/ml as measured by PCR) and anti-HBs negative
- Elevated serum ALT \> 2ULN but ≤ 10 × ULN as determined by two abnormal values taken ≥ 14 days apart during the six months before the first dose of study drug with at least one of the determinations obtained ≤ 35 days prior to the first dose.
You may not qualify if:
- Patients must not have received antiviral therapy for their chronic hepatitis B. Patients who are expected to need systemic antiviral therapy other than that provided by the study at any time during their participation in the study are also excluded. Exception: patients who have had less than 6 months treatment of NA(Nucleos(t)ide analog) and more than 1 year wash-out period for systemic antiviral therapy and negative results in the NA resistance test at baseline are not excluded.
- Positive test at screening for HAV IgM Ab, HCV-RNA or HCV Ab, HDV Ab or HIV Ab.
- Diagnosed hepatic cellular carcinoma
- Any evidence of decompensated liver disease (Childs B-C)
