Official Title: Autologous Bone Marrow Stromal Cell and Endothelial Progenitor Cell Transplantation in Patients With Ischemic Stroke: a Randomized Controlled Trial

Further study details as provided by Zhen-Zhou Chen, Southern Medical University, China:

Primary Outcome Measures:
  • Number of adverse events after infusion of BMSCs or EPCs. [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Changes in functional outcomes measured by the modified Rankin Scale (mRS) and the Barthel index (BI). [ Time Frame: 1 year ]

Estimated Enrollment: 20
Study Start Date: November 2011
Estimated Study Completion Date: March 2017
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BMSCs group Genetic: Autologous BMSCs transplantation

The first transplantation: 2.5 million cells per kg autologous BMSCs suspended in 100 ml saline plus 5% autologous serum are infused intravenously approximately 4 weeks after bone marrow aspiration.

The second transplantation: the same amount of cells are again transplanted approximately 1 weeks after initial boosting.

Other Names:
  • Autologous Bone marrow stromal cells transplantation
  • Autologous Mesenchymal stem cells transplantation
Experimental: EPCs group Genetic: Autologous EPCs transplantation

The first transplantation: 2.5 million cells per kg autologous EPCs suspended in 100 ml saline plus 5% autologous serum are infused intravenously approximately 4 weeks after bone marrow aspiration.

The second transplantation: the same amount of cells are again transplanted approximately 1 weeks after initial boosting.

Other Name: Autologous endothelial progenitor cells transplantation
Placebo Comparator: Control group Genetic: IV infusion of placebo
IV infusion of saline plus 5% autologous serum.
Other Name: Placebo control group

Detailed Description:
This study is a multi-center, single-blind, randomized, parallel controlled trail. Patients with acute cerebral infarcts within the middle cerebral arterial territory and with severe neurological deficits will be enrolled and randomly allocated into 3 groups: autologous BMSCs transplantation group, autologous EPCs transplantation group and Placebo control group. Randomization codes were established by the study statistician and were revealed only to the stem cell laboratory technician responsible for separating the cells into aliquots or preparing the placebo material. All patients will undergo a Bone Marrow aspiration procedure at 7 days after symptom onset. BMSCs and EPCs will be expanded ex vivo and then intravenously infused into own body, respectively. The control group will not receive cell therapy. Observe will followed for up to 1 year after the onset. Neurological score, neuroimaging, mortality of any cause, side effects, and new-onset comorbidities will be monitored and compared between each groups.
