Objectives

Narrative objectives1

The aim of this randomized controlled study is to examine the effectiveness and safety of adefovir monotherapy switched from lamivudine-adefovir combinational therapy for chronic hepatitis B or cirrhosis with lamivudine-resistance and sustained normal ALT and low HBV DNA load by lamivudine-adefovir combination therapy.

Interventions/Control_1

Adefovir-monotherapy arm: Switch from Lamivudine-Adefovir combinational therapy to Adefovir monotherapy, i.e., oral administration of Adefovir dipivoxil (brand name: Hepsera) in a daily dose of 10mg. If HBV DNA re-elevates or ALT re-elevates above two-fold of baseline afterwards, Lamivudine (brand name: Zefix) administration in a daily dose of 100 mg is re-started.

Interventions/Control_2

Lamivudine-adefovir combinational therapy arm: Combinational therapy of Lamivudine (brand name: Zefix) 100 mg per day and Adefovir dipivoxil (brand name: Hepsera) 10mg per day is continued.
