Brief Summary:
The aim of interferon therapy in HBeAg negative chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after treatment withdraw. In this trail, entecavir will add on patients with HBV DNA load ≥1000copies/ml after 3 months of peginterferon alpha 2a treatment, and the efficacies of the combine treatment will be evaluated by the rate of sustained viral response after 48 weeks of treatment and 24 week follow up.

Condition or disease Intervention/treatment Phase
Chronic Hepatitis B Drug: Entecavir Phase 4

Detailed Description:
HBeAg negative patients with HBV DNA load ≥1000copies/ml after 3 months of peginterferon alpha 2a treatment would be randomize enrolled into two groups, in Interventional group, patients will receive entecavir combine with peginterferon alpha 2a treatment for 48 weeks and followed 24 weeks. Patients in control group will be continue treated only by peginterferon alpha 2a for 48 weeks and followed 24 weeks after treatment. Serum HBV DNA load, HBsAg/anti-HBs level, HBeAg/anti-HBe will be tested at enrollment and every 3 months during the treatment course. Parameters of Liver and kidney function, and liver ultrasound examination will be tested with intervals 1-3 months. The efficacies of combined therapy were evaluated by the rate of sustained viral response after 48 weeks treatment and 24 weeks follow up compared with control group.

Arm Intervention/treatment
Experimental: entecavir with PEG-IFN a-2a
After enrolled, entecavir will added, and patients will receive treatment of PEG-IFN a-2a combine with entecavir for 48 weeks and 24 weeks of follow up after treatment.
Drug: Entecavir
After enrolled, entecavir will added, and patients will receive treatment of PEG-IFN a-2a combine with entecavir for 48 weeks and 24 weeks of follow-up after treatment.

No Intervention: control group
In this group, patients will be continue treated only by PEG-IFN a-2a for 48 weeks after enrolled and receive 24 weeks of follow up.



Primary Outcome Measures :
  1. rate of sustained virual response [ Time Frame: 72 weeks ]
    sustained viral response was defined as serum HBV DNA load was undetectable at the end of treatment and 24 weeks of follow-up.


Secondary Outcome Measures :
  1. rates of HBsAg loss during treatment course and at the end of follow-up [ Time Frame: 72 weeks ]
    HBsAg loss defined as HBsAg level ≤0.05 IU/ml
