  5. Patient has a history of ascites, variceal hemorrhage or hepatic encephalopathy.
  6. Patient is coinfected with HCV, HDV or HIV.
  7. Patient with clinical evidence of liver mass or hepatocellular carcinoma and α-Fetoprotein > 50 ng/mL
  8. Patient is pregnant or breast-feeding.
  9. 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. For males, condoms should be used. Females must 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)

  11. Patient has a significant gastrointestinal, renal, hepatic (decompensated), bronchopulmonary, biliary diseases excluding asymptomic GB stone, neurological, cardiovascular, oncologic or allergic disease. The patient with a benign tumor except for liver mass, excluded if judged by an investigator that the continuation of study would be interfered by the tumor.
  12. 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]

13.Patient whom investigator consider is not suitable in this study
