  • Previous treatment with interferon must have ended at least 6 months prior to the screening visit.
  • Patients previously treated with clevudine, entecavir, lamivudine, adefovir, telbivudine or any other investigational nucleoside for HBV infection.
  • Patient is coinfected with HCV, HDV or HIV.
  • Patient with clinical evidence of hepatocellular carcinoma
  • Patient has alpha-fetoprotein \> 400ng/mL.
