drugs within 2 months before study screening or during the study period

- Subjects who are currently participating in another investigational study or has been
taking any investigational drug within the last 4 weeks prior to screening visit.

- Patient is coinfected with HCV, HDV or HIV.

- Patient with following clinical evidence

- Decompensated liver cirrhosis (Child class B,C: CPT score 7) or hepatocellular
carcinoma

- Significant gastrointestinal, renal, bronchopulmonary, neurological,

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