Primary Outcome Measures:
  • frequency of dose limiting adverse events [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
  • proportion of subjects with a modified Rankin Scale (mRS) score of less than or equal to 2 [ Time Frame: 90 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • change in functional outcome throughout range of mRS scores [ Time Frame: 90 days ] [ Designated as safety issue: No ]
  • proportion of subjects with an excellent functional outcome [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    • mRS score = 0 to 1; and
    • NIHSS score = 0 to 1; and
    • Barthel Index score = greater than or equal to 95

  • frequency of adverse events [ Time Frame: 365 days ] [ Designated as safety issue: Yes ]
  • change in vital signs [ Time Frame: 365 days ] [ Designated as safety issue: Yes ]
  • change in safety labs [ Time Frame: 365 days ] [ Designated as safety issue: Yes ]
  • frequency of secondary infections [ Time Frame: 365 days ] [ Designated as safety issue: Yes ]
