Brief Summary
Entecavir (ETV) has shown superior ability to suppress hepatitis B virus (HBV) replication, histology improvement as well as low rate of emergence of resistant mutants. Out of range of clinical recommendations for treatment of chronic hepatitis B (CHB), chronic HBV carriers with persistently normal ALT and viral load more than 10\^5 copies/mL have progression of liver disease during long-term follow-up. In addition, certain proportions of these patients do have significant inflammation and fibrosis in liver histology. This study will be able to identify who are at risk of liver disease progression and evaluate efficacy of ETV regarding improvement of liver histology during short-term (1-year) and long-term ETV treatment (3-year).

Outcome Measures
Primary Outcomes (1)
Improvement of liver histology in patients with chronic hepatitis B virus infection and persistently normal ALT receiving entecavir. Please refer to "Description" section for the definiton of improvement of liver histology
1. The ratio of liver histology improvement in two groups. 2. Definition of improving liver histology is improvement in the necroinflammatory score (≥ 2 point decrease in Knodell necroinflammation score) and no worsening of fibrosis (≥ 1 point increase in the Knodell fibrosis score) at the week 52 liver biopsy compared to baseline.
1 year
Secondary Outcomes (2)
Undetectable HBV DNA
1 year and 3 year
the reduction of HBV DNA from baseline
1 year and 3 year

Interventions
Eligibility Criteria
You may qualify if:
- Male and female subjects aged between 18 and 65 year-old with history of chronic hepatitis B virus infection;
- Detectable HBsAg at screening and for at least 24 weeks prior to screening or detectable HBsAg for \< 24 week and negative for IgM core antibody and confirmation of chronic hepatitis on liver biopsy;
- ALT should be within normal range in recent one year and at least twice, which are at least 3 month apart;
- Normal ALT at screening;
- Screening HBV DNA of more than 10\^5 copies/mL by Roche AmplicorTM PCR assay performed by the central laboratory;
- Evidence of chronic hepatitis on liver biopsy (Knodell HAI Score \>= 4) performed ≤ 52 weeks prior to randomization;

- Other forms of liver disease e.g., alcoholic, autoimmune, biliary disease;
- Patients with evidence of decompensation of liver disease;
- Therapy with interferon, thymosin alpha or antiviral agents with activity against hepatitis B (e.g., adefovir, famciclovir, lamivudine, and telbivudine) within 24 weeks of randomization into this study;
- More than 12 weeks of prior therapy with nucleoside or nucleotide analogue antiviral agents with activity against hepatitis B (e.g., adefovir, famciclovir lamivudine, and telbivudine);
