Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female subjects ≥18 years of age
  • Clinical diagnosis of ischemic stroke involving cerebral cortex
  • Occurrence of a moderate to moderately severe stroke with a persistent neurologic deficit documented by a NIHSS score of 8 to 20 (inclusive) that does not change by ≥4 points during the initial screening period
