Adefovir DipivoxilLong-term Therapy • Safety and efficacy over 4-5 years demonstrated[1,2] • 55% in 4-yr cohort and 71% in 5-yr cohort had >/= 1-point improvement in Ishak fibrosis score • Majority of patients normalized ALT and suppressed serum HBV DNA < 1000 copies/mL • Adverse events uncommon: 3% increased serum creatinine >/= 0.5 mg/dL • Adefovir resistance mutations: 0%, 3%, 11%, 18%, and 29% detected at 1, 2, 3, 4, and 5 years, respectively • Durability of HBeAg seroconversion = 91%[3] • Addition of adefovir to lamivudine before and after liver transplantation prevents graft reinfection[4] 1.

Entecavir96 Weeks of Therapy • Among patients with only a virologic response after 48 weeks of therapy treated for a second year, 96% treated with entecavir vs 64% treated with lamivudine had an HBV DNA level < 300 copies/mL[1] • Cumulative virologic response for all patients through Week 96 (HBV DNA < 300 copies/mL) was 94% for entecavir and 77% for lamivudine[1] • No evidence of entecavir resistance found in nucleoside-naive patients lacking lamivudine resistance at study entry and treated for 96 weeks[2] 1.

Peginterferon alfa-2aEffect on Fibrosis Progression • Paired pretreatment and 24-week posttreatment biopsies analyzed • In HBeAg-positive patients, 33% had improved fibrosis and 33% had no change • In HBeAg-negative patients, 39% had improved fibrosis and 37% had no change • Rates of improved or stabilized fibrosis were significantly higher in patients with sustained serologic or virologic response at Week 72 Cooksley G, et al.
