About

This trial is conducted in China. The purpose of this study is to evaluate the pharmacokinetic similarity of Tafolecimab with different manufacturing process in healthy male subjects. Another purpose is to determine safety, and immunogenicity of sintilimab with different manufacturing process,also to determine Pharmacodynamics of Tafolecimab with different manufacturing process
