Tenney – 28 November 2006 – Comprehensive monitoring of genotypic and phenotypic antiviral resistance was performed on 673 entecavir (ETV)‐treated nucleoside naïve hepatitis B virus (HBV) patients. ETV reduced HBV DNA levels to undetectable by PCR (<300 copies/mL, <57 IU/mL) in 91% of hepatitis B e antigen (HBeAg)‐positive and ‐negative patients by Week 96.
