NCT00537537

Brief Summary

This study is to evaluate the antiviral efficacy of add-on adefovir to telbivudine in non-responders to telbivudine monotherapy after 24 and 36 initial weeks. Antiviral efficacy is assessed by hepatitis B virus (HBV) DNA non-detectability (PCR \<300 copies/ml) by week 104 with CHB.

Outcome Measures

Primary Outcomes (1)

  • Antiviral efficacy with adefovir combination assessed by HBV DNA non-detectability (PCR <300 copies/ml) by week 104.

Secondary Outcomes (5)

  • Antiviral efficacy with telbivudine alone assessed by HBV DNA non-detectability (PCR <300 copies/ml) at week 24 and 36.

  • HBeAg loss & HBeAg seroconversion (defined as a loss of HBeAg and a gain of detectable level of HBeAb).

  • Alanine Transaminase (ALT) normalization, in patients with raised levels at baseline.

  • Change in HBV DNA level (log10 copies/ml) from baseline to week 4, 8, 12, 24, 36, 52, 76 and 104.

  • Viral breakthrough, defined as increase of HBV DNA by 1 log10 copies/ml from treatment nadir, at any point after week 24.
