  Purpose

A study to examine the safety and potential effectiveness of the adult stem cell investigational product, MultiStem, in adults who have suffered an ischemic stroke. The hypothesis is that MultiStem will be safe and provide benefit following an ischemic stroke.


Condition Intervention Phase
Ischemic Stroke
 Biological: MultiStem
Biological: Placebo
 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)

Further study details as provided by Athersys, Inc:

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 ]
