Dose-Dependent Antithrombotic Activity Of An Orally Active Tissue Factor/Factor Viia Inhibitor Without Concomitant Enhancement Of Bleeding Propensity

The discovery of a highly potent and selective tissue factor/factor VIIa inhibitor is described. Upon oral administration of its double prodrug in the guinea pig, a dose-dependent antithrombotic effect is observed in an established model of arterial thrombosis without prolonging bleeding time. The pharmacodynamic properties of this selective inhibitor are compared to the behaviour of a mixed factor VIIa/factor Xa inhibitor. (c) 2006 Elsevier Ltd. All rights reserved.
