Rapid Delivery of Autologous Bone Marrow Derived Stem Cells in Acute Myocardial Infarction Patients. (AMIRST)
Intracoronary Infusion of Concentrated Autologous Bone Marrow Mononuclear Cells in Acute Myocardial Infarction Patients Utilizing a Novel Point-of-Care Device for Rapid-Delivery of Stem Cells (AMIRST)
The primary objective of the study is to determine the feasibility and safety of intracoronary administration of autologous bone marrow derived mononuclear cell product in patients at risk for clinically significant cardiac dysfunction following AMI.
The secondary objective of the study is to assess the effect on cardiac function and infarct region perfusion. A concurrent placebo control patient group meeting eligibility but not receiving autologous bone marrow derived stem cells will be evaluated similar to the treated group to assess the rate of significant spontaneous improvement in cardiac function.
연구 개요
상세 설명
Emerging evidence indicate that progenitor stem cells derived from bone marrow can be used to improve cardiac function in acute myocardial infarction patients. There is a great potential for stem cell therapy, using a variety of cell precursors to contribute to new blood vessel formation and muscle preservation in the myocardial infarct zone. The administration of cells via an infusion through the infarct related artery appears to be feasible and result in a clinical effect in some studies. Across the globe AMI is the leading cause of morbidity and mortality. This cannot be prevented by optimal standard therapies i.e. balloon or stent dilation of the infarct vessels.
The study is a double blind, placebo controlled, randomized, multicenter trial. Male or female patients between 18-75 years with first incidence of Acute Myocardial Infarction(AMI) and LVEF less than or equal to 40% are included in the study. Patients who have undergone successful percutaneous intervention (PCI) within ≤ 24 hours after onset of symptoms (PTCA/stent) or / and Thrombolysed patients having TIMI-3 flow are eligible to take part in the study.
A total of 30 subjects will be recruited and randomly assigned to receive concentrated BMMNC or placebo. All patients will undergo bone marrow aspiration within 3-10 days from the index event(infarction). Bone Marrow(BM) will be processed utilizing point of care technology. Following cell processing, the concentrated BMMNC or placebo control is infused directly into the infarct related artery using the stop flow method. Clinical follow up for all the subjects at 1,30, 60, 90, 180 and 360 days will be performed from the day of the procedure, with primary and secondary end points evaluated for both study arms.
