A review.FX06 (fibrin derived peptide Bβ15-42) is a promising new drug candidate indicated for the prevention of reperfusion injury in patients undergoing primary percutaneous intervention (PCI) for acute myocardial infarction (AMI).This novel peptide has been shown to prevent myocardial reperfusion injury in a number of acute and chronic animal models for this disease when given as a single bolus injection at the time of reperfusion.FX06 has a novel mechanism of action: it is a competitive inhibitor of the binding of fibrin E1 fragments to vascular endothelial (VE)-cadherin.Through this inhibition, it potently blocks the transmigration of inflammatory leukocytes through the endothelial barrier and prevents the downstream release of tissue-damaging mediators.FX06 has proven safe in acute and subchronic toxicol. studies and recently entered clin. development.
