Prophylactic prevention of bleeding episodes in patients with hemophilia A (congenital Factor VIII deficiency), including those with Factor VIII inhibitors (acquired antibodies against Factor VIII).
A bispecific monoclonal antibody that binds to both Factor IXa and Factor X, mimicking the cofactor function of natural Factor VIII to facilitate the conversion of Factor X to Factor Xa in the coagulation cascade.
Administered by subcutaneous injection (under the skin). Does not replace Factor VIII in emergency situations or for on-demand treatment. May increase risk of thrombotic microangiopathy and thrombotic events when used with bypassing agents. Regular monitoring may be required. The '-Kxwh' suffix indicates a specific product variant with unique naming.
