Brief Summary

  1. 1.Circulating bone marrow and blood vessel precursors home in to sites of ischemia and aid regeneration of injured tissue
  2. 2.Increasing the number of circulating precursors will improve in regeneration of damaged brain following ischemic stroke.

Outcome Measures

Primary Outcomes (1)

  • A statistically significant increase in: mortality/ non-fatal grade III or greater adverse events measured by the NCI Common Toxicity Scale/ incidence of recurrent strokes/ worsening of neurological disabilities measured by standardized stroke scales.

    6 weeks, 3 months, 6 months and 12 months after the first dose of the study drug.

Secondary Outcomes (1)

  • The secondary endpoints address the feasibility and efficacy of the study treatment: adequacy of bone marrow cell mobilization/ validation of imaging sequences/ Identification of optimal parameters for follow-up to be used in a subsequent larger trial.

    6 weeks, 3 months, 6 months and 12 months after the first dose of the study drug.

Eligibility Criteria

Age45 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is between 45 and 85 years of age
  • Patient is of either gender
  • The qualifying stroke is ischemic with a total NIH Stroke Score less than 18.
  • The stroke is classified as a partial anterior cerebral syndrome by the Oxfordshire Criteria.
  • NIHSS at baseline evaluation with:
  • \*Level of consciousness is not impaired as defined by an NIHSS between 0 and 1 on question 1a and
  • Hemiparesis as defined by
  • an NIHSS between 1 and 4 on questions 5 and/or
  • an NIHSS between 1 and 4 on questions 6.
  • Be able to start the experimental treatment a minimum of 3 days and a maximum of 10 days after the initial presentation with the stroke,
  • Patient or surrogate gives informed consent,
  • The patient is fluent in either French or English.

You may not qualify if:

  • Patient with hemorrhagic stroke,
  • Patients with a pre-morbid modified Rankin score \> 2 (Appendix 3b),
  • Patients with pre-morbid dementia by DSM-IV criteria.
  • Patients with a known allergic reaction to G-CSF or a component of G-CSF.
  • Patients with one or more significant co-morbidities expected to limit lifespan to less than 12 months. Examples include but are not limited to:
  • \> CHF Class II NYHA
  • Known prior or ongoing malignancy except non-melanomatous skin cancer.
  • Acute or chronic infections (HIV, TB, etc.. )
  • Other significant cardiac, renal, hepatic or pulmonary dysfunction.
  • Patients with organ dysfunction that would preclude tests required for this study. Examples include but are not limited to:
  • \*Serum Cr \> 200 μmol/L that would prevent administration of contrast dye.
  • Patients with a known history of bone marrow dysfunction, such as myeloid leukemia or myeloproliferative state that would prevent treatment with G-CSF.
  • Patients with metal implants that would preclude MRI examination including but not limited to patients with
  • pacemakers,
  • ear implants, and
  • +15 more criteria
