Change From Baseline in Serum Hepatitis B Surface Antigen (HBsAg) Level at Week 24
Baseline to Week 24

A mixed effect model for repeated measures (MMRM) was used to analyze HBsAg change from baseline, which included treatment, baseline HBsAg level (\> 5000 IU/mL or ≤ 5000 IU/mL), HBeAg baseline status (positive or negative), visit and treatment-by-visit interaction as fixed effect and visit as repeated measurement.

Secondary Endpoints
Composite Endpoint Measuring the Percentage of Participants With Hepatitis B Envelope Antigen (HBeAg) Loss and Seroconversion at Week 24
