Outcome Measures
Primary Outcome Measures
- Mean Change (Measured in log10 IU/mL) in Hepatitis B Surface Antigen (HBsAg) From Baseline at Week 24 [Baseline; Week 24]
The change from baseline to Week 24 in HBsAg (log10 IU/mL) was analyzed using a mixed model for repeated measures (MMRM). The model included treatment, baseline HBsAg (log10 IU/mL), baseline Hepatitis B Envelope Antigen (HBeAg) status (positive or negative), baseline alanine aminotransferase (ALT) level relative to upper limit of normal (ULN) (> 19 vs ≤ 19 IU/L for females; > 30 vs ≤ 30 IU/L for males), visit and treatment-by-visit interaction as fixed effects, and visit as a repeated measure.
Secondary Outcome Measures
