Little is known about efficacy of switching to tenofovir monotherapy for lam-resistant chronic hepatitis B patients who achieved a complete virological response to lamivudine plus adefovir. This study was to investigate the efficacy of switching to tenofovir monotherapy for lamivudine -resistant chronic hepatitis B patients with undetectable hepatitis B virus DNA while on lamivudine plus adefovir combination therapy
Name: lamivudine plus adefovir combination

Description: Proportion of patients with a sustained virological response (serum HBV DNA <20 IU/mL) at week 48
Measure: SVR Time: 48 WEEKAllocation: Randomized
Parallel Assignment
There is one SNP
