96 weeks combination of adefovir dipivoxil plus emtricitabine vs. adefovir dipivoxil monotherapy in the treatment of chronic heptitis B

Abstract

BACKGROUND/AIMS: In order to prevent the occurrence of drug-resistant mutants associated with treatment for chronic hepatitis B virus (HBV) infection, combination therapy is being developed. To determine the efficacy of adefovir dipivoxil (ADV) plus emtricitabine (FTC) combination therapy in chronic HBV infection. METHODS: Thirty treatment-nai ve, HBeAg-positive patients were randomized to combination ADV plus FTC (n=14) or ADV plus placebo monotherapy (n=16) for 96 weeks. HBV DNA was measured by polymerase chain reaction. Treatment was stopped in those with HBeAg seroconversion. RESULTS: The median decrease in HBV DNA at week 96 was higher in the combination group (-5.30 vs. -3.98 log(10)co..
