Ciraparantag is an anticoagulant reversal agent.1,2 It selectively binds to unfractionated heparin, enoxaparin, and Factor IXa (Kds = 28, 17, and 35 µM, respectively) over edoxaban , rivaroxaban , Factor Xa, Factor IX, thrombin , antithrombin, and fibrinogen, and only weakly binds to an enoxaparin-antithrombin complex and fondaparinux , in cell-free assays.1 Ciraparantag (200 µg/ml) prevents decreases in fibrin diameter induced by the Factor Xa inhibitor edoxaban in isolated human whole blood. It reduces edoxaban-, dabigatran-, apixaban-, rivaroxaban-, unfractionated heparin-, or enoxaparin-stimulated increases in tail transection-induced blood loss in rats.2
