Objectives

Narrative objectives1

The aim of this study is to compare continuation of lamivudine treatment with switching from lamivudine treatment to entecavir in the following viewpoints: (1)Development of virological breakthrough defined by more than 1 log copy/ml elevation of HBV DNA, and (2) development of entecavir-resistant mutant virus. The patients with chronic hepatitis B or cirrhosis who have been receiving lamivudine treatment for less than 2 years, and in whom lamivudine- resistant YMDD mutant virus has not been detected, are eligible.

Interventions/Control_1

Lamivudine continuing group:Lamivudine (brand name: Zefix) administration 100mg per day orally is continued. If HBV DNA elevates above 4 log copy/ml or YMDD mutant HBV is detected by PCR thereafter, the study is discontinued, and the patients may be treated with additional administration of adefovir dipivoxil (brand name Hepsera) 10 mg per day orally, switching to entecavir treatment 1.0mg per day orally, or continuation of lamivudine administration, according to the decision of the doctor considering the condition of liver.

Interventions/Control_2

Switch-to-entecavir arm: Discontinue lamivudine treatment and switch to entecavir (brand name: Baraclude) administration in a daily dose of 0.5mg before retiring at night. If HBV DNA elevates over 4 log copy/ml or YMDD mutant HBV is detected by PCR afterwards, the patient drops out of the study and may be treated with combination therapy of lamivudine 100mg and adefovir dipivoxil 10mg per day orally, or switching to entecavir treatment in a daily dose of 1.0mg orally, considering the condition of liver.
