Abstract | BACKGROUND: METHODS: Sixty-eight patients were randomized to entecavir 1 mg (n = 51) or placebo (n = 17) once daily for 24 weeks; 65 patients continued the study with entecavir for an additional 24 weeks. Lamivudine-containing HAART was continued throughout. RESULTS: At week 24, the mean HBV DNA in entecavir-treated patients was 5.52 log10 copies/ml versus 9.27 log10 copies/ml for placebo, and at week 48, it was 4.79 log10 copies/ml versus 5.63 log10 copies/ml, respectively. The mean HBV DNA change from baseline for entecavir was -3.65 log10 copies/ml (versus + 0.11 for placebo, P < 0.0001) and alanine aminotransferase normalization in 34% of patients (versus 8% for placebo, P = 0.08). At 48 weeks, mean change in HBV DNA reached -4.20 log10 copies/ml in patients who received entecavir for the entire 48 weeks. The frequency of adverse events with entecavir and placebo was comparable. Through 48 weeks, no clinically relevant changes in HIV viremia or CD4 cell counts were identified. CONCLUSION: In this study, entecavir was associated with rapid, clinically significant reductions in HBV DNA, with maintenance of HIV viremia suppression, in HIV/HBV coinfected patients with HBV viremia while on lamivudine treatment.
