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

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;
