Efficacy and Safety Study of Adefovir and Entecavir for Elderly With Chronic Hepatitis B

Completed
Conditions
Hepatitis B, Chronic
Interventions
Registration Number
NCT02075294
Lead Sponsor
Ying-Jie Ji
Brief Summary

It is estimated that 350-400 million people have chronic infection with hepatitis B virus (HBV) all over the world. In china, 93 million individuals suffer from this chronic condition. Currently, seven medications are approved for the treatment of hepatitis B: two formulations of interferon and four nucleos(t)ide analogues. The Chinese population has one of the longer average life spans, and the size of the aged population has been increasing rapidly. As a result, the prevalence of elderly patients with HBV has increased, and the potential for development of cirrhosis or hepatocellular carcinoma in such patients is real. Hence, treatment of elderly patients with HBV is an important issue. However, ADV or ETV has become first choice due to the more side effect of INF and the resistant of LAM and LdT. But treatment outcomes with ADV and ETV in elderly are not known yet. In this study, we will evaluate and compare the efficacy and tolerability of ADV and ETV between younger and older patients with HBV. The aims of the present study are (1)to assess the benefits of ADV or ETV therapy for elderly patients with chronic hepatitis B, and (2)to determine differences in the emergence rate of side effect.
