Exclusion Criteria:

  1. Subjects with liver diseases other than hepatitis B, including hepatitis C, hemochromatosis, primary sclerosing cholangitis; alcoholic, drug-related or autoimmune liver diseases; primary liver cancer and indeterminate nodules on liver imaging test;
  2. A history or manifestations of liver decompensation (e.g. Child-Pugh Class B or C, or ascites, gastrointestinal bleeding, hepatic encephalopathy or spontaneous bacterial peritonitis, etc.);
  3. Transient elastography at screening revealing FibroScan value ≥ 9 kPa or liver biopsy evidencing hepatic fibrosis within 24 months;
  4. The following laboratory findings: total serum bilirubin> 2×ULN; serum alpha-fetoprotein>50μg/L; serum albumin <3.5g/dL; international normalized ratio (INR)> 1.25; serum creatinine > 1.5×ULN; any laboratory outliers of clinical significance that in the investigator's opinion may interfere with the interpretation of efficacy or safety data;
