Abstract

Summary: Reports on the efficacy and safety of long‐term entecavir treatment in chronic hepatitis B (CHB) predominantly genotype B or C are insufficient. This study presents the efficacy and safety of entecavir maleate in Chinese CHB patients. Patients were randomly assigned to receive 48‐week treatment with either 0.5 mg/day entecavir (group A) or 0.5 mg/day entecavir maleate (group B), and then all patients received treatment with 0.5 mg/day entecavir maleate from week 49. Two hundred and seventy‐five patients with CHB (HBeAg‐positive: 218) were analysed, predominantly (98.5%) with genotype B or C. Baseline characteristics were balanced. For the HBeAg‐positive CHB patients, the mean HBV DNA level decreased similarly (A: by 6.36 log10 IU/mL vs B: by 6.31 log10 IU/mL) between groups at week 144. The percentages of patients who achieved undetectable HBV DNA were similar (A: 70.59% vs B: 66.67%) between groups. Similar HBeAg loss rates (A: 43.53% vs B: 40.23%; P >.05) and HBeAg seroconversion rates (A: 21.52% vs B: 21.18%) were achieved. For the HBeAg‐negative CHB patients, similar reductions in HBV DNA levels from baseline (A: by 6.13 log10 IU/mL vs B: by 5.65 log10 IU/mL) and percentages of patients who achieved undetectable HBV DNA (A: 100% vs B: 100%) were achieved. The overall incidence of adverse events was comparable between groups. In conclusions, 48‐week administration of entecavir maleate and entecavir showed similar efficacy and safety in Chinese patients with CHB. Long‐term entecavir maleate treatment was effective and safe in CHB patients.
