Brief Summary

Tenofovir alafenamide (TAF) is a new prodrug of tenofovir developed to treat patients with chronic hepatitis B virus (HBV) infection. Whereas, the long-term effect of TAF to liver fibrosis is still unknown. Here, we enrolled treatment naive CHB patients with biopsy-proven significant fibrosis (METAVIR fibrosis stage ≥ F2). All enrolled subjects will be treated with TAF monotherapy for 96 weeks. After 96 weeks of therapy, the second liver biopsy will be performed to evaluate the rate of liver fibrosis regression. During this study, all subjects will be assessed for laboratory tests, imaging examination at baseline, first 12-week and every 24-week during follow-up.
