| Secondary | Number of Participants With a Combination of ALT Normalization and HBV DNA Less Than 50 IU/mL, Plus HBeAg Seroconversion Through Week 96 in Treated Participants | Hepatitis B virus DNA by PCR was measured using the Roche COBAS TaqMan - HPS assay and was reported in IU/mL. Baseline was the last value measured prior to or on the date of the first dose of study therapy. Normalization in ALT= ALT ≤ 1.0*ULN. HBe seroconversion was determination of presence of HBeAb and loss of HBeAg. The method used for the detection of HBeAg seroconversion was the DiaSorin - Anti HBe enzyme immunoassay kit. | The intent-to-treat method of Non-Completer = Failure was used through Week 48 in which all treated participants were analyzed, and participants with missing data at the analysis week were considered failures.
