Clinical Trial Summary

This study is designed to evaluate the safety and antiviral activity of tenofovir disoproxil fumarate (TDF, tenofovir DF) compared to adefovir dipivoxil (ADV) for the treatment of HBeAg-positive chronic hepatitis B. Participants will receive either TDF or the approved hepatitis B therapy ADV. After 48 weeks all participants will be switched to open-label TDF.


Clinical Trial Description

Efficacy of TDF versus ADV will be evaluated for histologic improvement, reductions in serum HBV DNA, changes in liver enzymes, and the generation of antibody to the virus. Safety will be assessed by evaluating adverse events, laboratory abnormalities and the development of drug-resistant mutations. After 48 weeks, all participants will receive open-label TDF, and the efficacy and safety of TDF will be monitored for the remainder of the study. ;


Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
