Clinical Trial Summary

The primary objectives of this study are to evaluate the safety, tolerability and pharmacokinetic (PK) profiles of single-dose, dose-escalated, abdominal subcutaneous injection of GB224 in Chinese healthy adult subjects. The secondary objectives are to preliminarily understand the immunogenicity and pharmacodynamic variable (IL-6) of single abdominal subcutaneous injection of GB224 in Chinese healthy adult subjects.
