Comparison of Telbivudine Versus Lamivudine on the Early Dynamics and Kinetics of Viral Suppression in Chronic Hepatitis B
- Registration Number
- NCT00710216
- Lead Sponsor
- University of Ulm
- Brief Summary
This study examines the effect of telbivudine compared to lamivudine on the early viral kinetics in patients with chronic hepatitis B. The virus Kinetics is measured by the viral load (HBV-DNA) reduction in the serum during the first 12 weeks of therapy.
