NCIt definition : A recombinant form of the vitamin K-dependent glycoprotein and coagulation factor
VIIa (FVIIa), that can be used for the treatment of bleeding episodes and perioperative
management in patients with hemophilia, congenital Factor VII (FVII) deficiency, and
Glanzmann's thrombasthenia. Upon intravenous administration, eptacog alfa temporarily
replaces missing endogenous FVIIa. When complexed with tissue factor (TF), FVIIa activates
coagulation Factor X (FX) to Factor Xa (FXa), as well as coagulation Factor IX to
Factor IXa. Factor Xa, in complex with other factors, then converts prothrombin to
thrombin. This converts fibrinogen to fibrin and leads to the formation of a hemostatic
plug, thereby inducing local hemostasis and prevents bleeding.;
