Primary Outcome Measures:

Primary efficacy endpoint: "therapeutic response", defined as reduction of serum HBV DNA to below 5 log10 copies/mL, coupled with normalization of serum alanine aminotransferase levels OR loss of detectable serum HBeAg.

Secondary Outcome Measures:

Secondary efficacy endpoints: Improvement of liver histology, serum HBV DNA changes, normalization of serum alanine aminotransferase levels, HBeAg and HBsAg loss and seroconversion.

February 2003
