Inclusion criteria

Patients who were between 18 and 60, inclusive.
Patients with HBV DNA ³1 x 106 copies/mL within 30 days of baseline.
Patients who were documented to be HBsAg positive for > 6 months. (The documentation of positive HBsAg for the previous 6 months included previous laboratory reports of HBsAg positive or HBeAg positive at least 6 month ago or IgM anti-HBc negative and IgG anti-HBc positive at screening).
Patients who were HBeAg positive.
Patients with ALT levels which were in the range of ≥1.2 and < 15 times of the upper limit of normal (x ULN) and bilirubin levels less than 2.0 mg/dL, prothrombin time of less than 1.7 (INR), and a serum albumin level of at least 3.5 g/dL.
Women of child bearing potential with a negative serum (β-HCG) pregnancy test taken within 14 days of starting therapy.
Patients who were able to give written informed consent prior to study start and to comply with the study requirements.

Exclusion criteria

Patients who were currently receiving antiviral, immunomodulatory or corticosteroid therapy.
Patients previously treated with lamivudine, lobucavir, famciclovir, adefovir or any other investigational nucleoside for HBV infection.
Previous treatment with interferon that had ended less than 6 months prior to the screening visit.
Patients with a history of ascites, variceal hemorrhage or hepatic encephalopathy.
Patients co-infected with HCV, HDV or HIV.
Patients with clinical evidence of liver mass or with alpha-fetoprotein > 50 ng/mL
Patients who were pregnant or breast-feeding.
Patients who were unwilling to use an "effective" method of contraception during the treatment and for up to 3 months after cessation of therapy. For males, condoms should be used. Females had to be surgically sterile (via hysterectomy or bilateral tubal ligation) or post-menopausal or using at least medically acceptable barrier method of contraception ( i.e. IUD, barrier methods with spermicide or abstinence)
Patients with a clinically relevant history of abuse of alcohol or drugs.
Patients with a significant gastrointestinal, renal, hepatic (decompensated), bronchopulmonary, biliary diseases except asymptomatic GB stone, neurological, cardiovascular, oncologic or allergic disease.

The patients with a benign tumor were excluded if judged by an investigator that the continuation of study would be interfered by benign tumor.
Patients with creatinine clearance less than 60mL/min as estimated by the following formula :

(140-age in years) (body weight [kg]) (72) (serum creatinine [mg/dL]) [Note: multiply estimates by 0.85 for women]

Patients who were found to have YMDD HBV DNA polymerase mutation at baseline were to be excluded from the overall efficacy evaluation and analyzed separately. They were to be included in the overall safety evaluation.
