  Purpose

The primary purpose of the clinical study is to determine the safety of a modified stem cell SB623 when administered to chronic, stable ischemic stroke patients. A second purpose is to determine whether SB623 might improve stroke symptoms. Chronic, stable ischemic stroke patients must be between 6 and 60 months after their stroke, and with only this one prior stroke, and and with no further improvement from physical therapy.


Condition Intervention Phase
Chronic Ischemic Stroke
Biological: SB623
Phase 1
Phase 2

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase 1/2A Study of the Safety and Efficacy of Modified Stromal Cells (SB623) in Patients With Stable Ischemic Stroke

Further study details as provided by SanBio, Inc.:

Primary Outcome Measures:
  • Safety [ Time Frame: Two years ] [ Designated as safety issue: Yes ]
    Safety will be evaluated using the WHO safety criteria, by periodic MRIs, frequent laboratory monitoring, and by periodic measurements of possible humoral and cell-mediated immunological changes


Secondary Outcome Measures:
  • Improvement in stroke symptoms and brain metabolism [ Time Frame: Two Years ] [ Designated as safety issue: No ]
    Possible improvement in stroke symptoms will be determined by a variety of neurological assessments: European Stroke Scale, NIH Stroke Scale, Modified Rankin Score, and Fugl-Meyer assessment. Possible improvement in brain metabolism will be assessed using FDG-PET scans.


Estimated Enrollment: 18
Study Start Date: January 2011
Estimated Study Completion Date: May 2015
Estimated Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SB623
Administration of modified stem cells, SB623
Biological: SB623
SB623, a modified stem-cell product, will be administered at 3 dose levels. Each patient in one of three groups will be given a dose of 2.5, 5.0, or 10 million cells once. Each group will be completed before going to the next higher-dose group.

Detailed Description:

Chronic, stable stroke patients have no existing alternative treatments after rehabilitation therapy. SB623, a modified stem cell preparation, has been shown to improve motor function when administered in animal models of stable stroke. Safety studies in animals have shown no adverse events attributed to SB623. Patients who meet the entry criteria for this study will have regular examinations, radiological evaluations (CT, MRI, PET), and be followed for two years. Regular neurological evaluations will also be done using standard questionnaires, with occasional video recording if improvements are evident. Key entry criteria for this study, in addition to 6-60 months post-ischemic stroke, include moderately severe symptoms--e.g., difficulty standing or walking, and/or difficulty using arms or hands, and/or speech impediments.

  Eligibility

Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:
