Thrombosis and novel hemophilia therapies: the fine line between clotting and bleeding.

ABSTRACT: The availability of novel nonfactor therapeutics is revolutionizing the management of hemophilia in individuals with inhibitory antibodies, as well as making prophylaxis more convenient even in the absence of inhibitors. Unfortunately, the use of these products has been associated with thrombotic events that are not typically seen with factor replacement. These are primarily seen when a patient on a nonfactor therapy experiences breakthrough bleeding and concomitantly receives another hemostatic agent. This video addresses thrombotic complication in 3 nonfactor products: (1) emicizumab, a bispecific antibody that mimics the cofactor activity of factor VIII; (2) fitusiran, an small interfering RNA that knocks down synthesis of antithrombin; and (3) concizumab, an antibody that blocks inhibi
