Letaxaban is an orally active, tetrahydropyrimidin-2(1H)-one derivative and inhibitor of coagulation factor Xa (activated factor X) with anticoagulant activity. Letaxaban may have anti-inflammatory potential in addition to its anti-thrombotic effects. Letaxaban had been in phase II clinical trials by Takeda for the treatment of venous thromboembolism (VTE). However, this research has been discontinued. Takeda had discontinued their phase II clinical trials for the treatment of acute coronary syndrome (ACS) since the results failed to meet the target efficacy and safety profile.
