Recruitment Status
Primary Trial ID Number
An international, multi-centre, double-blind, randomised, placebo-controlled clinical trial with central core lab analyses to determine the safety of intra-coronary infusion of enriched CD133+, bone marrow-derived, autologous progenitor cells in patients 5-10 days after acute percutaneous coronary revascularization (primary PCI) for ST-segment elevation myocardial infarction (STEMI).

Study Design
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Study Type
Other : CD133+ infusion, Other : placebo infusion

Study Arm Groups : 1, 2

Intervention Type
See Interventions above
Primary Outcome Measures
  • PRIMARY SAFETY ENDPOINT Comparison of progression in coronary atherosclerosis burden proximal and distal to the stented segment of the infarct-related artery in treated and control groups.; at 6 months post-infusion; PRIMARY EFFICACY ENDPOINT Comparison of changes in myocardial thickening in non-viable akinetic / hypokinetic LV wall segments as determined by cardiac magnetic resonance imaging (cMRI) in treated and control groups.; at 6 and 24 months
Secondary Outcome Measures
  • SECONDARY SAFETY ENDPOINT (a) Development of ventricular arrhythmias including failed sudden cardiac death. (b) Development of congestive heart failure.; At all follow up's; SECONDARY EFFICACY ENDPOINTS (a) Changes in % global LV ejection fraction (EF) compared with baseline as determined by cMRI and echocardiography pre- and post-cell infusion subsequent to primary PCI.; at all follow up's; SECONDARY EFFICACY ENDPOINTS (b)Assessment of epicardial resistance and microvascular resistance, index of myocardial resistance and absolute coronary blood flow measurements in the infarct related artery.; at 6 months follow up; SECONDARY EFFICACY ENDPOINTS (c) The feasibility of the CliniMACS® Reagent System to yield 5x106 CD133+ cells from 100-150 ml of autologous bone marrow.; prior to the infusion
