Napsagatran [RO 466240], a reversible and highly selective thrombin inhibitor, was in development with Roche for use in myocardial infarction and thrombosis. Napsagatran efficiently inhibits and delays thrombin generation in human coagulating plasma. This reduced thrombin generation might be caused by inhibition of thrombin-mediated feedback reactions during blood coagulation. Ro 46-6240 inhibited clot-bound thrombin three times more potently than fluid-phase thrombin (IC50 19 vs 56 ng/ml) while hirudin was two times (IC50 8 vs 3 ng/ml) and heparin six times (IC50 1,205 vs 200 ng/ml) less active against clot-bound thrombin compared with fluid-phase thrombin.

Sample Use Guides

In Vivo Use Guide

One hundred and ten patients with acute proximal deep-vein thrombosis were randomized in a sequential dose-finding design, to receive continuous intravenous infusion of napsagatran, a novel synthetic thrombin-inhibitor, at a fixed dose of 5 mg/h (n = 37) or 9 mg/h (n = 26), or APTT-adjusted unfractionated heparin (n = 47).

Route of Administration: Intravenous

In Vitro Use Guide

Napsagatran [RO 466240] was nearly as potent as r-hirudin for inhibiting extrinsic thrombin generation (IC50 418 vs 229 nM) and intrinsic thrombin generation (IC50 463 vs 343 nM) despite a much lower affinity of Ro 466240 for thrombin (Ki apparent: 0.3 nM) in a purified buffer system.
