Study Details
Study Description
Brief Summary
The intent of this clinical study is to answer the questions:
-
Is the proposed treatment safe
-
Is treatment effective in improving the disease pathology of patients after Stroke and clinical outcomes?

Detailed Description
Adipose-Derived Stromal Cells (ASCs) are a novel therapy for patients suffering from stroke. By injecting ASCs either into the internal carotid artery, these regions may become populated with the ASCs, thereby potentially restoring brain function. ASCs are a patient-derived ("autologous") cell transplantation technology that is delivered to the patient into the internal carotid artery and intravenously. The therapy is composed of cells derived from a patients' own adipose tissue that are isolated within approximately 1 hour and immediately delivered back to the patient.

Outcome Measures
Primary Outcome Measures
- Improvement in clinical function from baseline as assessed by the NIH stroke scale at three months [3 months]
- Number of participants with adverse events [1 week]
The safety of adipose-derived stem cell injection will be evaluated by assessment of the frequency and nature of adverse events occurring during the study injection and up to the 6-month period following treatment.
- Number of participants with adverse events at 2 weeks [two weeks]
- Number of participants with adverse events at 4 weeks [4 weeks]
- Improvement in clinical function from baseline as assessed by the NIH stroke at 6 months [6 months]
- Number of participants with adverse events at 3 weeks [3 weeks]
- Improvement in clinical function as assessed by Barthel Scale compared to baseline at 6 months [6 months]
Secondary Outcome Measures
- Improvement in clinical function as assessed by Modified Rankin Score compared to baseline at 3 months [3 months]
- Improvement in clinical function as assessed by Barthel Scale compared to baseline at 3 months [3 months]
- Improvement in Magnetic resonance imaging (MRI) scan compared to baseline at three months [3 months]
- Improvement in clinical function as assessed by Modified Rankin Score compared to baseline at 6 months [6 months]
- Improvement in clinical function as assessed by Barthel Scale compared to baseline at 6 months [6 months]
- Improvement in Magnetic resonance imaging (MRI) scan compared to baseline at six months [6 months]
