This is an open-label study that will be conducted at three sites in China to characterize the PK/PD profile, safety and tolerability of Recombinant Human Serum Albumin/interferon alpha2b Fusion Protein in HBV subjects. Subjects will receive a single dose of Recombinant Human Serum Albumin/interferon alpha2b Fusion Protein or active comparator Pegasys at Day 0. A multipule-dose administration in HBV subjects will last 12 weeks after four weeks washout period.
The purpose of this study is to evaluate the dosages of recombinant human serum albumin/interferon alpha2b fusion protein injection on HBV subjects. The secondary purposes is to get the PK/PD data in recombinant human serum albumin/interferon alpha2b fusion protein injection on HBV subjects.
