NCT01300234

Brief Summary

This is a multi-centre, double blind, double dummy, randomised, controlled study to evaluate the efficacy and safety of TDF 300mg QD versus ADV 10mg QD in Chinese subjects with CHB. This study is designed to demonstrate the superiority of TDF 300mg QD over ADV 10mg QD in treating Chinese subjects with CHB (hepatitis B e antigen \[HBeAg\] positive subjects and HBeAg negative subjects). It will also provide long-term efficacy and safety data (up to 240 weeks) for TDF 300 mg administered once daily.

Outcome Measures

Primary Outcomes (1)

  • Participants With Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) <400 Copies/Milliliter (mL) at Week 48

    The number of participants with Hepatitis B Virus (HBV) deoxyribonucleic acid (DNA) \<400 copies/milliliter (mL) at Week 48 in the hepatitis B e antigen (HBeAg)-positive and HBeAg-negative population was assessed. HBeAg is a viral protein that is secreted by hepatitis B-infected cells. It is associated with chronic hepatitis B infections and is used as a marker of active viral disease and a participant's degree of infectiousness. A positive result indicates that the participant has high levels of virus in the blood and greater infectiousness. Usually, a negative result indicates that the participant has lower levels of virus in the blood and is less infectious. A "non-completers equal failures" approach is used for the analysis in ITT population. Only those participants available at the specified time points (represented by n=X in the category titles) were analyzed.

    Week 48

Secondary Outcomes (14)

    Weeks 96, 144, 192, and 240

  • Change From Baseline of Log 10 Copies/mL HBV DNA at Weeks 48, 96, 144, 192 and 240

    Baseline, Weeks 48, 96, 144, 192 and 240

  • Number of Participants With Alanine Aminotransferase (ALT) Normalization at Weeks 48, 96, 144, 192 and 240 in Participants Who Had Abnormal ALT at Baseline

    Baseline; Weeks 48, 96, 144, 192 and 240

  • Number of Participants With Histological Improvement at Weeks 48 and 240 Who Had a Baseline Knodell Necroinflammatory Score (KNS) >=2.

    Baseline; Week 48 and Week 240

  • Number of HBeAg-positive Participants Achieving HBeAg Loss and HBeAg Seroconversion at Weeks 24, 48, 96, 144, 192 and 240.
