Eksperimentel: telbivudine
telbivudine 600 mg tablet orally (p.o.) once daily for up to 156 weeks.
Patients with HBV DNA ≥ 300 copies/mL at Week 24 were to initiate add-on therapy with tenofovir 300 mg tablets p.o. once daily for the remaining weeks of treatment.
The investigator was to initiate tenofovir add-on therapy within 2 weeks of central laboratory confirmation.
Patients with HBV DNA < 300 copies/mL at Week 24 were to continue to receive telbivudine monotherapy

Tidsramme: week 52
|
The primary objective of the study is to compare the efficacy of Roadmap-Concept-based telbivudine treatment versus Roadmap-Concept-based tenofovir treatment in HBeAg-negative CHB patients.
The rate of HBV DNA < 300 copies/mL (51 IU/mL) at week 52 will be used for the comparison of the efficacy.
The hypothesis is that the aggregated rate of HBV DNA < 300 copies/mL (51 IU/mL) at week 52 of Telbivudine (ARM 1) is non-inferior to Tenofovir (ARM 2).
For the "treating missing as failure" analysis, patients who came for their primary endpoint Week 52 visit within the ± 7-day window but not on the exact designated day of the visit were treated as "missing data."

eGFR Change From Baseline in Telbivudine Arm vs Tenofovir Arm Over the Course of the Study
Tidsramme: Baseline, 24 weeks, 52 weeks, 104 weeks, 156 weeks
|
eGFR changes were calculated using the Modification of Diet in Renal Disease (MDRD) formula: GFR = 186 x (sCr)^(-1.154)
x (age)^-0.203
with Female: Multiply GFR by 0.742; Black: Multiply GFR by 1.210.
sCr is Serum Creatinine in mg/dl (measured at each scheduled visit).
Age in years at visit (=[sCr sample collection date -Date of birth]/365.25).
Weight in kilograms, as measured at the visit or the closest previous visit Safety population.
