Clinical Trial Summary

This study evaluates generic emtricitabine(FTC) in Chinese naive chronic hepatitis B patients. Patients were divided into 2 groups: HBeAg positive Chronic hepatitis B(CHB)group and HBeAg negative Chronic hepatitis B(CHB)group.

Description:

Generic emtricitabine(FTC) has been approved for treatment of naive chronic hepatitis B(CHB) patients in China. Yet data are limited for this agent. The investigators design this trial to test the effect of FTC in Chinese CHB which including naive HBeAg positive and Negative CHB patients. Response guided therapy strategy is adopted for patients who can not achieve HBV DNA negativity at week 24 FTC treatment, which means FTC and adefovir are combined for these patients.
