Randomized Controlled Trial Multicenter Study Clinical TrialA randomized, double-blinded, placebo-controlled, dose-ranging study measuring the effect of an adenosine agonist on infarct size reduction in patients undergoing primary percutaneous transluminal coronary angioplasty: the ADMIRE (AmP579 Delivery for Myocardial Infarction REduction) study.
Evidence suggests that myocardial ischemic preconditioning and reperfusion injury may be mediated by adenosine A1 and A2 receptors. AMP579 is a mixed adenosine agonist with both A1 and A2 effects. In animal models of acute myocardial infarction (MI), AMP579 reduced infarct size at serum levels of 15 to 24 ng/mL. ⋯ AMP579 was safe at the doses tested, but it did not reduce infarct size. There was a trend toward greater myocardial salvage in treated patients with anterior MI.
