Suffered the onset of an acute ischemic stroke that can be evaluated and treatment initiated within 9 hours after the onset of acute ischemic stroke symptoms.
Screening NIHSS score of 10 to 16, inclusive
Readily accessible peripheral venous access for clinical trial material (CTM) administration and blood sampling
Ability to understand the requirements of the study and be willing to provide written informed consent as evidenced by signature on an informed consent document approved by an institutional review board or independent ethics committee, and agree to abide by the study restrictions and return for the required assessments.

Exclusion Criteria:

An intracerebral or subarachnoid hemorrhage per screening/baseline computerized tomography scan or susceptibility-weighted magnetic resonance imaging

A candidate for either:

thrombolytic therapy, or have been treated with thrombolytic therapy for the current stroke
mechanical thromboembolectomy, or have been treated with mechanical thromboembolectomy for the current stroke
Delirious, comatose or stuporous or demented, or having a mental impairment that in the investigator's opinion renders the subject incapable to participate in the study
Have seizure(s) anytime from stroke onset to screening/baseline NIHSS evaluation
Neurological or non-neurological comorbidities that in the investigator's opinion may lead, independent of the current stroke, to further deterioration in the subject's neurological status during the trial period, or may render the study's neurological assessments inconclusive for the purpose of evaluating solely the stroke's effects
Likely to undergo a procedure involving cardiopulmonary bypass during the study period
Suffered a myocardial infarction in the last 90 days
Any medical condition that in the investigator's opinion may threaten the subject's ability to complete the study (e.g., concurrent significant or life-threatening diseases, such as malignancies or end stage organ failure)
Rapid spontaneous improvement of neurological signs during screening/baseline assessments
Premorbid neurological deficits and functional limitations assessed by a pre-stroke Modified Rankin Scale score of > 1
Suffered a stroke within 90 days of the screening/baseline assessments that is either diagnostically confirmed or assumed to be in the same cerebral territory as is the current acute stroke
Either severe hypertension or hypotension, as measured by at least 2 consecutive supine measurements taken 10 minutes apart prior to randomization.
Significant current renal or hepatic disease(s): a serum creatinine concentration of >2.5 mg/dL; alanine aminotransferase, aspartate aminotransferase, or gamma-glutamyl transferase values that are three times greater than the upper limit of normal.
Have a platelet count of <100,000/mm3 or, for patients on oral anticoagulants at study entry, INR of >4

Severe anemia as measured by a hemoglobin value of < 7 g/dl.
