  Purpose

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.

Primary Outcome Measures:
  • 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). [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
    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).


Secondary Outcome Measures:
  • antiviral efficacy by the rate of patients achieving HBV DNA < 300 copies/ml at Week104, and at Week156 [ Time Frame: 104 weeks; 156 weeks ] [ Designated as safety issue: No ]
    To assess the antiviral efficacy, as evaluated by rate of patients achieving HBV DNA <300 copies/mL (51 IU/mL) at Week104, at Week156. In patients who achieve HBV DNA <300copies at Week 104, rate of patients with maintained HBV DNA <300 copies at Week 156

  • antiviral efficacy by serum HBV DNA reduction and time to achieve HBV DNA <300 copies/ml at Week104, and at Week156 [ Time Frame: over the course of the study ] [ Designated as safety issue: No ]
    To assess the antiviral efficacy, as evaluated by serum HBV DNA reduction from baseline, and time to achieve HBV DNA < 300 copies/mL (51 IU/mL). In patients who achive HBV DNA < 169 copies/ml at Week104, teh rate of patients with maintained HBV DNA <169 copies at Week156.

  • rate of HBsAg loss [ Time Frame: over the course of the study ] [ Designated as safety issue: No ]
    To assess the rate of HBsAg loss and HBsAg seroconversion (defined as loss of HBsAg and development of HBsAb) over the course of the study

  • biochemical efficacy [ Time Frame: Week 52; Week 104; Week 156 in patients with elevated ALT at baseline. ] [ Designated as safety issue: No ]
    To assess the biochemical efficacy as evaluated by rate of patients with ALT normalization

  • safety endpoint [ Time Frame: at Week 52, Week 104 and Week 156 ] [ Designated as safety issue: Yes ]
    To assess the safety endpoints as evaluated by incidence of death, AE, SAE, AESI and graded laboratory abnormalities

  • eGFR change in telbivudine arm vs tenofovir Arm over the course of the study [ Time Frame: 52 weeks, 104 weeks, 156 weeks ] [ Designated as safety issue: No ]
    eGFR changes from baseline to Week52, Week104 and Week156 for the overall population and sub-populations of patients with renal function impairment at baseline (eGFR 60-90 ml/min/1.73m2 or 60-80 ml/min/1.73m2). Percentage of patients with abnormal baseline eGFR shifting to normal eGFR at Week52, Week104 and Week156
