A Clinical Study of SSS40 in Healthy Chinese Volunteers

Summary

This is a single-center, randomized, double-blind, single-administration, escalating-dose, placebo-controlled, phase I clinical trial to evaluate the safety, tolerability, pharmacokinetics, and immunogenicity of SSS40 in healthy subjects in China. A total of 8 subcutaneous dose groups were planned, including 1mg, 3mg, 10mg, 20mg, 30mg, 45mg, 60mg, 80mg. Starting from the 10mg group, a sentinel approach was adopted, whereby 2 subjects were first enrolled in the group, and randomized to the sentinel group in a 1:1 ratio (test drug:placebo), with the sentinels blinded, and then the remaining subjects in the group were randomized according to a 1:1 ratio (test drug:placebo), and the sentinel group was blinded. After completion of the 72-h safety assessment in the sentinel group, the remaining subjects in the group were randomized to receive the drug according to the test drug group and the placebo group.
