Tecarfarin (also known as ATI-5923), an anticoagulant, is a vitamin K reductase antagonist. Tecarfarin is participating in phase III clinical trials for the treatment of thromboembolism and thrombosis. On March 11, 2019, Espero BioPharma Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) for tecarfarin for the prevention of systemic thromboembolism of cardiac origin. Tecarfarin is metabolized by esterases, escaping metabolism by the cytochrome P450 system and thereby avoiding cytochrome P450-mediated drug-drug or drug-food interactions as well as genetic variations found in the cytochrome P450 system.
