Efficacy and Safety Study of DP-b99 in Treating Acute Ischemic Stroke

Summary

The purpose of this trial is to determine if intravenous administration of the metal ion trapping agent DP-b99 up to 9 hours following acute ischemic stroke onset, and then for 3 additional days (4 consecutive days in total) is effective in improving long term outcome. Patients will be followed up for 3 months after the stroke.
