Primary Outcome Measures:
  • Antiviral Activity: Proportion of patients with HBeAg loss [ Time Frame: Screening, Day1(predose), every 4 weeks during treatment period(48weeks) ]
  • Safety Endpoints:Laboratory tests, Adverse Events, Vital signs, ECG [ Time Frame: Screening, Day1(predose), every 4 weeks during treatment period(48weeks), ECG: screening, Week48 ]

Secondary Outcome Measures:
  • Proportion of patients with HBV DNA below LOD, Biochemical improvement, Proportion of patients with seroconversion [ Time Frame: Screening, Day1(predose), every 4 weeks during treatment period(48weeks) ]
  • Immunological endpoints: Alterations in immunological parameters before, after therapy, particularly with regards to the proliferative a [ Time Frame: Day1(predose), Week 8, 16, 24, 28, 32, 40 and 48 ]

Estimated Enrollment: 70

  6. Patient is able to give written informed consent prior to study start and to comply with the study requirements.

Exclusion Criteria:

  1. Patient is currently receiving antiviral, immunomodulatory, cytotoxic or corticosteroid therapy.
  2. Patients previously treated with interferon, lamivudine, adefovir, entecavir, telbivudine or any other investigational nucleoside for HBV infection.
  3. Patient has a history of ascites, variceal hemorrhage or hepatic encephalopathy.
  4. Patient is coinfected with HCV, HDV or HIV.
  5. Patient with clinical evidence of decompensated liver disease or HCC
  6. ANA > 1:160 and positive anti-smooth muscle antibody as evidence of autoimmune hepatitis
  7. Patient is pregnant or breast-feeding.
  8. Patient is unwilling to use an "effective" method of contraception during the study and for up to 3 months after the use of study drug ceases.
  9. Patient has a clinically relevant history of abuse of alcohol or drugs.
  10. Patient has a significant immunocompromised, gastrointestinal, renal, hematological, psychiatric, bronchopulmonary, biliary diseases excluding asymptomatic GB stone, neurological, cardiac, oncologic or allergic disease or medical illness that in the investigator's opinion might interfere with therapy. The patient with a benign tumor, excluded if judged by an investigator that the continuation of study would be interfered by the tumor.
  11. Patient has 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]
