Autologous Bone Marrow Stem Cells in Middle Cerebral Artery Acute Stroke Treatment.

Phase 2CompletedNCT00761982

Hospital Universitario Central de Asturias20 enrolled

Overview

The aim of the study is to determine the safety and efficacy on an autologous CD34+ subset bone marrow stem cell infusion into the middle cerebral artery in patients who have suffered acute middle cerebral artery stroke.

The proposed trial will involve the recruitment of a total of 20 patients. The cells will be collected from ten subject recruited as cases, via bone marrow sampling. The aspirate will be centrifuged on a Ficoll density gradient to isolate mononuclear cells, which will be resuspended in heparinized isotonic saline for infusion into the area of the stroke intra-arterially using the middle cerebral artery. The investigators will monitor each case and control for a period of 6 months post-stem cell infusion. Initially, they will be subjected to a review after one month,three months and finally 6 months. Assessment of adverse events will be by physical examination and measurement of laboratory parameters. Assessment of efficacy will be by physical examination and the measurement of laboratory, CT and MRI parameters.
