Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the efficacy and safety following the Roadmap Concept strategy with an initial monotherapy using either telbivudine or tenofovir in HBeAg negative CHB patients. The data from the study should allow for the validation of the Roadmap concept in a prospective manner, for both telbivudine and tenofovir treated HBeAg negative CHB patients. As part of a post-approval commitment to the European Health Authorities, the data will also be used to provide an optimized clinical treatment strategy for better clinical use of telbivudine in European HBeAg negative patients. Furthermore, the data from the study will contribute to a better scientific understanding, disease management and treatment of HBeAg negative CHB patients.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 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

Drug: telbivudine
600 mg film-coated tablets taken as 600 mg once daily
Other Names:
  • LDT600
  • Active Comparator: tenofovir

    tenofovir 300 mg tablets 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 telbivudine 600 mg tablet p.o. once daily for the remaining weeks of treatment. The investigator was to initiate telbivudine 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 tenofovir monotherapy

    Drug: tenofovir disoproxil fumarate
    300 mg tablets taken as 300 mg once daily

    Outcome Measures

    Primary Outcome Measures

    1. Percentage of Participants Achieving HBV DNA < 300 Copies/mL (51 IU/mL) at Week 52 (rITT Population) - [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."

    Secondary Outcome Measures

    1. Percentage of Patients Achieving Secondary Efficacy Endpoints (rITT) [week 24, 52, 104]

      To assess the antiviral efficacy, as evaluated by the percentage of patients achieving HBV DNA <300 copies/mL (51 IU/mL), ALT normalization, HBsAg loss, HBsAg conversion, virologic breakthrough (VB) at study visit, cumulative VB by study defined study period, cumulative treatment-emergent resistance

    2. Percentage of Participants Achieving Secondary Efficacy Endpoints at Week 156 (mITT) [156 weeks]

      To assess the antiviral efficacy, as evaluated by the percentage of patients achieving HBV DNA <300 copies/mL (51 IU/mL) at Week156, ALT normalization, HBsAg loss, development of HBsAg conversion , cumulative tx emergent resistance, HBV DNA <300 copies/mL with HBV DNA <7 log at Baseline

    3. eGFR Change From Baseline in Telbivudine Arm vs Tenofovir Arm Over the Course of the Study [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.

    4. Secondary Outcome
    Title eGFR Change From Baseline in Telbivudine Arm vs Tenofovir Arm Over the Course of the Study
    Description 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.
    Time Frame Baseline, 24 weeks, 52 weeks, 104 weeks, 156 weeks

    Analysis Population Description
    Safety population consisted of patients who received at least 1 dose of study drug and had 1 post-baseline safety assessment.
