Brief Summary

This is a randomized, double-blinded, controlled Phase I three-arms study of CMAB807X administered by subcutaneous injection. This study will characterize the pharmacokinetic, pharmacodynamics, safety and immunogenicity of CMAB807X Pre- and Post-change in Manufacturing Site, and Post-change CMAB807X versus Xgeva® #Denosumab# in healthy male subjects after a single dose

Detailed Description

This is a randomized, double-blind, parallel-controlled, single-dose phase I three-arms clinical study in healthy Chinese male subjects. A total of 252 subjects were planned to be enrolled and randomly assigned to the test group or the bridging control group or bioequivalence control group in a 1:1:1 ratio. Subjects in three groups received a single abdominal subcutaneous injection of pre- or post-change CMAB807X or Xgeva® #Denosumab# 120 mg, respectively. Subjects in three groups were observed for 140 days after administration to evaluate similarities in pharmacokinetics, pharmacodynamics, safety, and immunogenicity.
