Clinical Trial Summary

This Phase 1b multiple center, randomized, double-blind, placebo-controlled study is a dose escalation trial evaluating the safety, tolerability, PK characteristics and efficacy of SY-007 after injection in acute ischemicstroke patients. The immunogenicity of SY-007 will be evaluated and this study will provide the recommended dosage for subsequent clinical trials.
