FVIII (PK subgroup only)

Bioverativ Therapeutics Inc. · Phase 3 active Small molecule ✓ Verified May 2026

FVIII (PK subgroup only) is a Coagulation factor replacement Small molecule drug developed by Bioverativ Therapeutics Inc.. It is currently in Phase 3 development for Hemophilia A (factor VIII deficiency) — prevention and treatment of bleeding episodes.

FVIII is a recombinant coagulation factor VIII that replaces deficient or dysfunctional clotting factor to restore hemostasis in hemophilia A patients.

FVIII (PK subgroup) is a small molecule used to treat severe Hemophilia A and study its pharmacokinetics. It is administered as concentrated FVIII or Factor VIII (rFVIIIFc), such as Advate, to patients with Hemophilia A.

Mechanism of action

Factor VIII is a critical cofactor in the intrinsic coagulation cascade that works with von Willebrand factor and factor IX to activate factor X, ultimately leading to thrombin generation and fibrin clot formation. In hemophilia A, deficiency or dysfunction of factor VIII impairs this cascade, resulting in bleeding tendency. Recombinant FVIII replacement therapy restores coagulation capacity and prevents or treats bleeding episodes. The PK subgroup designation indicates this study focuses on pharmacokinetic characterization of the factor VIII product.
