A Phase 2 Double Blinded, Randomized, Placebo Controlled Dose Escalation Study to Evaluate the Efficacy and the Safety of GM602 in Patients With Acute Middle Cerebral Artery Ischemic Stroke Within an 18-hour Treatment Window

The purpose of this research study is to determine whether the investigational drug GM602, is
effective and safe in the treatment of ischemic stroke (strokes caused by a blood clot
blocking the flow of blood through one, or more of the blood vessels supplying the brain)
when administered up to 18 hours after symptoms begin.

Stroke is a serious and life threatening disease. About 85% of all strokes are ischemic,
caused by a blood clot or plaque that blocks a blood vessel in the brain. The thrombolytic
drug tissue plasminogen activator (tPA) is the only early treatment for acute ischemic stroke
approved by the FDA. Treatment with tPA must be administered within three hours of the stroke
onset. Furthermore, tPA treatment carries a recognized risk of bleeding in the brain. GM602
is an investigational drug that may act as a neuroprotectant in patients who have had a
stroke. It is thought to stop cell death and reduce inflammation in the injured area of the
brain. This study is designed to evaluate the safety and efficacy of GM602 administered
intravenously to patients in three consecutive daily doses of 320 mg/dose or 480 mg/dose, the
initial dose administered within 18 hours after onset of acute ischemic stroke in the Middle
Cerebral artery region.
