Trial ID: NCT00704106


We propose a largely retrospective study with short-term prospective follow-up in a subgroup of patients who have not yet been treated with 48 weeks of entecavir following partial response to adefovir. The aim of the study is to describe sequential virologic response to adefovir and entecavir.
