Telbivudine or Tenofovir Treatment in HBeAg-negative Chronic Hepatitis B Patients Based on the Roadmap Concept

March 6, 2018 updated by: Novartis Pharmaceuticals

OPTIMA: A Randomized, Open-label, 156-week Treatment Study to Evaluate the Efficacy and Safety of Telbivudine or Tenofovir Treatment in HBeAg-negative Chronic Hepatitis B Patients Based on the Roadmap Concept

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving HBV DNA < 300 Copies/mL (51 IU/mL) at Week 52 (rITT Population) -
Time Frame: 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."
week 52

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Patients Achieving Secondary Efficacy Endpoints (rITT)
Time Frame: 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
week 24, 52, 104
Percentage of Participants Achieving Secondary Efficacy Endpoints at Week 156 (mITT)
Time Frame: 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
156 weeks
eGFR Change From Baseline in Telbivudine Arm vs Tenofovir Arm Over the Course of the Study
Time Frame: 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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
