Brief 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.

Primary Outcome Measures
NameTimeMethod
Safety and tolerance of SY-007From Day 0 to Day 90

Number of patients with treatment-emergent adverse events and number of patients who died over 90 days

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Excellent Outcome in Barthel index (BI) Score at Day 8, Day30, Day60, Day 90Day 8, Day30, Day60, Day 90

Excellent BI outcome is defined as a score of \>=95. BI consists of 10 items that measure a participant's daily functioning, specifically the activities of daily living and mobility.

Immunogenicity of SY-007From Day 0 to Day 30

Anti-Drug antibody evaluation
