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

6 mars 2018 uppdaterad av: 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.

Åtgärdsbeskrivning
Tidsram
Percentage of Participants Achieving HBV DNA < 300 Copies/mL (51 IU/mL) at Week 52 (rITT Population) -
Tidsram: 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
Tidsram: 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.
