Study of Telbivudine in Chronic Hepatitis B

Chang Gung Memorial Hospital160 enrolled

Overview

The purpose of this study is to evaluate the safety, tolerability and antiviral efficacy of telbivudine by maintained suppression of hepatitis B virus (HBV) DNA (\<=300 copies/ml or 60IU/ml, undetectable by current polymerase chain reaction (PCR) - based assays) in HBeAg positive/negative patients at physician's general practice.

Primary objective: To evaluate the antiviral efficacy of telbivudine by maintained suppression of HBV DNA(\<=300 copies/ml or 60 IU/ml,undetectable by current PCR-based assays) in HBeAg positive patients from Week 24 to Week 48. Methodology: This will be an open-label, prospective, observational, single-center and single arm post marketing surveillance study. Number of patients: It is estimated to enroll 240 intent-to-treat patients in Taiwan. Population: Male or female patients, at least 18 years of age diagnosed with chronic hepatitis B with liver disease and telbivudine is prescribed by physicians based on clinical justification. And patients are able to communicate well, provide written informed consent, and willing to participate in the entire study.
