Altuviiio

Generic name: Antihemophilic Factor (recombinant), Fc-VWF-XTEN Fusion Protein-ehtl
Drug class: Miscellaneous coagulation modifiers

Usage of Altuviiio

Altuviiio is a once-weekly recombinant factor VIII replacement therapy that can be used by Hemophilia A patients routinely to prevent bleeding, or used on-demand to treat an acute bleed. Altuviiio works as a replacement for the missing coagulation factor VIII that hemophilia A patients need for effective blood clotting, so Altuviiio lowers their risk of bleeding.

Hemophilia is a genetic disorder that impairs the ability of a person’s blood to clot correctly, this leads to excessive and unexpected bleeding. Hemophilia A is caused by a missing or defective clotting protein called factor VIII (FVIII), which means the blood does not clot when it needs to.  Patients with severe hemophilia A can have excessive spontaneous bleeds without apparent cause, this can be bleeding inside the body or outside the body. Patients with milder hemophilia A are likely only to have significant bleeding if they have surgery or after severe injury. 

Altuviio is given as a weekly infusion to hemophilia A patients, as a replacement for their missing or defective factor VIII clotting protein, to decrease their risk of bleeding  

Altuviiio is a first-in-class FDA-approved high-sustained factor VIII replacement therapy that is given as a once-weekly intravenous infusion. FDA approval was supported by data from the Phase 3 XTEND-1 study (NCT04161495) and XTEND-Kids study (NCT04759131).
