The aim of the study was to assess the safety and efficacy of intracoronary administration of allogeneic CDCs in the multicentre, randomized, double-blinded, placebo-controlled, intracoronary ALLogeneic heart STem cells to Achieve myocardial Regeneration (ALLSTAR) trial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>We enrolled patients 4\u2009weeks to 12\u2009months after MI, with left ventricular ejection fraction (LVEF) \u226445% and LV scar size \u226515% of LV mass by magnetic resonance imaging (MRI). A pre-specified interim analysis was performed when 6-month MRI data were available. The trial was subsequently stopped due to the low probability of detecting a significant treatment effect of CDCs based on the primary endpoint. Patients were randomly allocated in a 2:1 ratio to receive CDCs or placebo in the infarct-related artery by stop-flow technique. The primary safety endpoint was the occurrence, during 1-month post-intracoronary infusion, of acute myocarditis attributable to allogeneic CDCs, ventricular tachycardia- or ventricular fibrillation-related death, sudden unexpected death, or a major adverse cardiac event (death or hospitalization for heart failure or non-fatal MI or need for left ventricular assist device or heart transplant). The primary efficacy endpoint was the relative percentage change in infarct size at 12\u2009months post-infusion as assessed by contrast-enhanced cardiac MRI. We randomly allocated 142 eligible patients of whom 134 were treated (90 to the CDC group and 44 to the placebo group). The mean baseline LVEF was 40% and the mean scar size was 22% of LV mass. No primary safety endpoint events occurred. There was no difference in the percentage change from baseline in scar size (P\u2009=\u20090.51) between CDCs and placebo groups at 6\u2009months. Compared with placebo, there were significant reductions in LV end-diastolic volume (P\u2009=\u20090.02), LV end-systolic volume (P\u2009=\u20090.02), and N-terminal pro b-type natriuretic peptide (NT-proBNP) (P\u2009=\u20090.02) at 6\u2009months in CDC-treated patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Intracoronary infusion of allogeneic CDCs in patients with post-MI LV dysfunction was safe but did not reduce scar size relative to placebo at 6\u2009months.
