Clinical Trial Summary

To evaluate the safety, tolerability, PK and preliminary PD of SSS11 for injection in chinese healthy adult volunteers.

Description:

This is a phase I, open label, single-dose, dose-increasing study to assess the safety, tolerability and PK characteristics of healthy humans after injection of SSS11, provide a reference for subsequent clinical studies and give preliminary assessment of the immunogenicity and PD of SSS11.
