Primary Outcome Measures:
  • The proportion of subjects who have newly reported hepatitis B-related complications during AI463049 (reported by Phase III treatment groups) [ Time Frame: data is collected every 6 months ] [ Designated as safety issue: Yes ]

    defined as follows:

    • Hepatic cirrhosis (Diagnosis requires biopsy or imaging study)
    • Esophageal Varices (Grade 1 or higher on endoscopy or barium swallow)
    • Bleeding esophageal varices
    • Ascites (Present on physical exam or imaging study)
    • Hepatic encephalopathy (≥ Stage 2)
    • Hepatocellular carcinoma
    • Spontaneous bacterial peritonitis
    • Gastric varices
    • Bleeding gastric varices
    • Hepatorenal syndrome


Secondary Outcome Measures:
  • To determine the proportion of subjects who have a HBV Deoxyribonucleic acid (DNA) by Polymerase chain reaction (PCR) of < 300 copies/mL over the AI463049 follow-up period by the phase III treatment group [ Time Frame: Every 6 months ] [ Designated as safety issue: No ]
  • To determine the proportion of subjects who have Alanine transaminase (ALT) ≤ 1.0 x Upper limit of normal (ULN) over the AI463049 follow-up period by the phase III treatment group [ Time Frame: Every 6 months ] [ Designated as safety issue: No ]
  • To determine the proportion of subjects who were Hepatitis B e antigen (HBeAg) positive at the beginning of Phase III trials who have HBeAg loss or HBe seroconversion over the AI463049 follow-up period by the phase III treatment group [ Time Frame: Every 6 months ] [ Designated as safety issue: No ]
  • To determine the number of anti-HBV medications following enrollment in AI463049 by the phase III treatment group [ Time Frame: Every 6 months ] [ Designated as safety issue: No ]
  • To determine all cause mortality by the phase III treatment group [ Time Frame: Every 6 months ] [ Designated as safety issue: No ]
  • To determine HBV-related mortality by the phase III treatment group [ Time Frame: Every 6 months ] [ Designated as safety issue: No ]
  • To determine Non-hepatic malignancies by the phase III treatment group [ Time Frame: Every 6 months ] [ Designated as safety issue: No ]
