Brief Summary:
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

Condition or disease Intervention/treatment Phase
Proportion of Patients With a Sustained Virological Response (Serum HBV DNA <20 IU/mL) at Week 48 Drug: lamivudine plus adefovir combination Drug: Tenofovir Disoproxil Fumarate Phase 3
