You may qualify if…

• Subject is aged 18 to 90 years.
• Subject has an NIHSS of 6 to 25.
• Subject is able to receive the first IP within 24 hours after stroke symptoms onset.
• Neuroimaging Inclusion Criteria:
• Subject is able to undergo a contrast brain perfusion with either MRI or computed tomography (CT).
• Subject has Target Mismatch Profile on MRI (perfusion is included) or CTP: ischemic core volume ≤70 mL, mismatch ratio ≥1.2 and mismatch volume ≥5 mL.

You may not qualify if…

• Subject has large ischemic core volume >70 mL or ASPECTS ≤5.
• Subject has symptoms of suspected subarachnoid hemorrhage.
• Subject has imaging evidence of acute intracranial hemorrhage, intracranial tumor, arteriovenous malformations, other central nervous system lesions that could increase the risk of bleeding, or aneurysm requiring treatment.
• Subject has significant mass effect with midline shift.
• Subject has pre-existing medical, neurological, or psychiatric disease that would confound the neurological or functional evaluations.
• Subject has current uncontrolled hypertension despite treatment.
• Subject has INR >1.7 or abnormal aPTT or platelet count <100,000/mm\^3.
• Subject has received conventional heparin or new oral anticoagulants within 48 hours before the first IP administration.
• Subject has blood glucose concentration <50 mg/dL or >400 mg/dL.
• Subject has moderate or severe hepatic, renal, and/or active infectious disease.
• Subject is lactating, pregnant, or planning to become pregnant during the study.
• Subject has had history of sICH, prior AIS, myocardial infarction, or serious head trauma within 90 days before Screening.
• Subject has had any major surgery within 90 days before Screening.
• Subject has had a bleeding event within 21 days before Screening.
• Subject has puncture of noncompressible vessels within 7 days before Screening.
