Primary Outcome Measures:
  • The proportion of subjects who achieve: 1) HBV DNA < 50 IU/mL (approximately 300 copies/mL) using the Roche COBAS® TaqMan HBV Test for use with the High Pure System (HPS) assay; and 2) HBeAg seroconversion [ Time Frame: At Week 48 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of subjects with HBV DNA < 50 IU/mL [ Time Frame: At Week 48 ] [ Designated as safety issue: No ]
  • Proportion of subjects with HBV DNA < LOQ [ Time Frame: At Week 48 ] [ Designated as safety issue: No ]
  • Proportion of subjects with serum ALT < = 1 x ULN [ Time Frame: At Week 48 ] [ Designated as safety issue: No ]
  • Proportion of subjects with HBe seroconversion [ Time Frame: At Week 48 ] [ Designated as safety issue: No ]
  • Proportion of subjects who achieved sustained HBeAg seroconversion during off-treatment follow-up among subjects who achieved HBe seroconversion at end of treatment [ Time Frame: At 5 years of study participation ] [ Designated as safety issue: No ]
  • The number and percent of subjects with adverse events, serious adverse events, discontinuations due to adverse events, and HBV disease progression [ Time Frame: At Week 48 ] [ Designated as safety issue: Yes ]
  • Proportion of subjects who maintained HBeAg seroconversion at Week 96 (end of blinded therapy) among subjects who achieved HBeAg seroconversion [ Time Frame: at Week 48 ] [ Designated as safety issue: No ]
  • Histological analysis among subjects with available liver biopsy [ Time Frame: At 5 years of study participation ] [ Designated as safety issue: No ]
