Percentage of Participants With a Virologic Response at Week 48 - Treated Population
기간: Week 48
|
Virologic response was defined as Hepatitis B virus (HBV) Deoxyribonucleic acid (DNA) less than 50 international units per milliliter (IU/mL); approximately 300 copies/mL.
Percentage was calculated as number of participants with virologic response at Week 48 divided by the number of treated participants.
Treated participants were evaluated using non-completer (NC) = failure (F).
The HBV DNA by polymerase chain reaction (PCR) was measured using the Roche COBAS(REGISTERED) TaqMan - High Pure System (HPS) assay, in a central laboratory.
The results were reported in IU/mL, with the limit of quantification (LOQ) = 29 IU/mL and lower limit of detection (LLD) = 6 IU/mL.
HBV DNA measurements were transformed by the log10 scale when analyzed as a continuous variable, using log10(LOQ-1) for values below LOQ.

Testing of HBV genotype was performed at baseline for all treated patients and for participants at Weeks 48 and 96 with primary non-response or virologic breakthrough.
Emergent genotypic resistance to study drugs was defined as follows: Emergent = not detected at baseline; entecavir (ETV) resistance (ETVr): participant's sample was to have rtM204V/I/S and any substitution at rtT184, rtS202, or rtM250; tenofovir (TDF) resistance (TDFr) which was based on adefovir (ADV)-mutations: participant's sample was to have rtA181T/V, rtN236T, or (rtA194T and rtM204V/I/S).
Primary non-response was defined as < 1 log10 decrease in HBV DNA from baseline on treatment at or after Week 12. Virologic breakthrough was defined as ≥ 1 log10 increase in HBV DNA over nadir on treatment, either confirmed or last on-treatment followed by discontinuation of study therapy.
