Clinical Trial Summary

This study was a single-center, randomized, double blind, placebo-controlled, single-dose, dose-increasing study to evaluate the safety, tolerability, PK characteristics, PD effect, and immunogenicity of CM338 injection administered intravenously or subcutaneously at different doses in healthy subjects.

Description:

The study included screening period, baseline period, administration and hospitalization observation period, and safety follow-up period.

Sixty-six healthy volunteers will be enrolled and randomized into 8 groups.
