Brief Summary

This study is designed to determine the safety and efficacy of SHPL-49 intravenous infusion for 7 consecutive days in the treatment of acute ischemic stroke subjects.

Detailed Description

Trial Objectives:

The primary objective of this study is to determine the effectiveness of different doses of SHPL-49 intravenous infusion for 7 consecutive days in the treatment of acute ischemic stroke subjects within 8h after onset.

The secondary objective is to determine the safety of different doses of SHPL-49 intravenous infusion for 7 consecutive days in the treatment of acute ischemic stroke subjects within 8h after onset.

Trial Design:

This study is a Phase II, multicenter, randomized, double Blind, placebo-Controlled design. Participants receive twice daily dosing for 7 consecutive days, or once on Days 1 and Day 8 and twice daily on Days 2 to Day 7, with each subject scheduled to receive 14 doses throughout the clinical trial. 270 Participants will be randomized 1:1:1 to SHPL-49 injection treated group (3 ampoules of SHPL-49 injections, Bis in die（BID）), SHPL-49 injection treated group (6 ampoules of SHPL-49 injections , BID) and placebo group (BID).

4. Stroke with rapid improvement of symptoms before intravenous thrombolysis, or acute ischemic symptoms suspected to be caused by other causes;

5. Patients who are ready to receive or have receive intravascular therapy;
