Stroke
 Biological: autologous bone marrow mononuclear cells
 Phase 1
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment

Primary Purpose: Treatment
Official Title: Phase 1/2A Study of Intravenous Autologous Bone Marrow Mononuclear Cell Transplantation for Patients After Cerebral Embolism

Further study details as provided by National Cerebral and Cardiovascular Center:

Primary Outcome Measures:
  • Improvement of NIHSS（National Institute of Health Stroke Scale） [ Time Frame: 30 days after treatment ] [ Designated as safety issue: No ]
  • Frequency of change for the worse in NIHSS [ Time Frame: 30 days aftrer treatment ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Mean level of mRS (modified Rankin Scale) [ Time Frame: 30 days after treatment ] [ Designated as safety issue: No ]
  • Frequency of death [ Time Frame: day 30 after treatment ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 12
Study Start Date: May 2008
Estimated Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: autologous bone marrow mononuclear cell
On day 7-10 after stroke, patient has 25ml of bone marrow cells aspiration. Mononuclear cells are purified by Ficoll and administrated intravenously.
 Biological: autologous bone marrow mononuclear cells
intravenous administration of autologous bone marrow derived mononuclear cells obtained from 25ml of bone marrow on day 7-10 after stroke (only once in that period)
Experimental: autologous bone marrow mononuclear cells
On day 7-10 after stroke, patient has 50ml of bone marrow cells aspiration. Mononuclear cells are purified by Ficoll and administrated intravenously.
 Biological: autologous bone marrow mononuclear cells
intravenous administration of autologous bone marrow derived mononuclear cells obtained from 50ml of bone marrow on day 7-10 after stroke (only once in that period)
