Completed

Phase 1/2 Results

Eligibility Criteria

Inclusion Criteria

- Subjects with cerebral ischemia at any location producing a serious measurable deficit by NIHSS scale and who received study medication within 5 hours after the onset of the symptom. A serious measurable deficit by NIHSS was defined as the NIHSS  9 and  20 (for brain stem stroke, patients with NIHSS > 20 were included).
- Subjects were  18 years old, of either sex.
- Subjects or his/her legal guardians demonstrated their willingness to participate in the study and comply with its procedures by signing a written informed consent.
- Subjects with Modified Rankin Scale > 1.

Exclusion Criteria

- Onset of symptoms on awaking from sleep.
- Intracranial bleeding detected on a pretreatment head computerized tomographic (CT) scan.
- Clinical presentation suggested a subarachnoid hemorrhage even if the head CT scan was normal.
