Brief Summary

This study is designed to determine the efficacy and safety of SHPL-49 intravenous infusion in acute ischemic stroke patients.

Detailed Description

The objective of this study is to determine the efficacy and safety of SHPL-49 intravenous infusion for 7 consecutive days in acute ischemic stroke patients within 8hours after onset. This study is a Phase III, multicenter, randomized, double-blind, placebo-controlled parallel design. Participants receive twice daily dosing for 7 consecutive days, or once on Day 1 and Day 8 and twice daily on Days 2 to 7, with each participant scheduled to receive 14 doses throughout the clinical trial. 1096 participants will be randomized 1:1 to SHPL-49 injection treated group and placebo group.
