Abstract
One year of treatment with entecavir (0.5 mg daily) in nucleoside-naive
patients with hepatitis B e antigen (HBeAg)-positive or HBeAg-negative chronic
hepatitis B (CHB) resulted in significantly improved liver histology and
virological and biochemical endpoints in comparison with lamivudine. Patients
who received at least 3 years of cumulative entecavir therapy in phase 3
studies and a long-term rollover study and underwent long-term liver biopsy
were evaluated for improvements in histological appearance. Sixty-nine
patients [50 HBeAg-positive and 19 HBeAg-negative] receiving entecavir therapy
underwent long-term liver biopsy (median time of biopsy = 6 years, range = 3-7
years). Histological improvement was analyzed for 57 patients who had adequate
baseline biopsy samples, baseline Knodell necroinflammatory scores >/=2, and
adequate long-term biopsy samples. At the time of long-term biopsy, all
patients in the cohort had a hepatitis B virus DNA level <300 copies/mL, and
86% had a normalized alanine aminotransferase level. Histological improvement
(>/=2-point decrease in the Knodell necroinflammatory score and no worsening
of the Knodell fibrosis score) was observed in 96% of patients, and a
>/=1-point improvement in the Ishak fibrosis score was found in 88% of
patients, including all 10 patients with advanced fibrosis or cirrhosis at the
phase 3 baseline. Conclusion: The majority of nucleoside-naive patients with
CHB who were treated with entecavir in this long-term cohort achieved
substantial histological improvement and regression of fibrosis or cirrhosis.
