OBJECTIVE: To compare the efficacy of 48 week-Entecavir therapy with that of Adefovir therapy for chronic hepatitis B patients. METHODS: In this open-label study we randomly assigned 125 CHB patients to receive 0.5 mg of entecavir (n = 56) or 10mg of adefovir (n = 69) once daily for 48 weeks. RESULTS:HBV DNA, ALT and HBeAg were quantified at baseline and at 0, 24, 48 weeks. At week 24 and 48, more patients in entecavir group than in adefovir group achieved undetectable serum HBV DNA level (68% vs 35%, 84% vs 49%, P < 0.05). The percentage of patients with normal ALT level in the two groups at week 48 was similar (100% vs 94%, P > 0.05). Among the HBeAg positive patients, more patients in entecavir group than in adefovir group had HBeAg loss at week 24 and 48 (23% vs 7%, 44% vs 15%, P < 0.05). The ratio of HBeAg seroconversion was similar in the two groups at week 24 (18% vs 7%, P > 0.05), but more patients in entecavir group than in adefovir group achieved HBeAg seroconversion at week 48 (33% vs 12%, P < 0.05). The retreated patients in the entecavir group had a higher chance to achieve undetectable serum HBV DNA level (79% vs 34%, P < 0.05), HBeAg loss (42% vs 17%, P > 0.05), and seroconversion (26% vs 17%, P > 0.05), than these in the adefovir group. The safety profiles and adverse event profiles were similar in the two groups. CONCLUSIONS: Compared to adefovir, entecavir is more potent to suppress HBV replication.
