  • Percentage of Participants With Hepatitis B e Antigen (HBeAg) Loss at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
  • Percentage of Participants With Hepatitis B e Antigen/Antibody (HBeAg/Ab) Seroconversion at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
  • Time to Onset of HBeAg Loss [ Time Frame: From Baseline to Week 52 ] [ Designated as safety issue: No ]
  • Time to Onset of HBeAg/Ab Seroconversion [ Time Frame: From Baseline to Week 52 ] [ Designated as safety issue: No ]
  • Percentage of Participants With Hepatitis B s Antigen (HBsAg) Loss at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
  • Percentage of Participants With Hepatitis B s Antigen/ Antibody (HBsAg/Ab) Seroconversion at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
  • Mean Alanine Aminotransferase (ALT) Level at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
  • Percentage of Participants With Alanine Aminotransferase (ALT) Normalization at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
  • Time to Onset of ALT Normalization [ Time Frame: From Baseline to Week 52 ] [ Designated as safety issue: No ]
