Humate-P® for von Willebrand Disease—High-Quality VWF

The mainstay of von Willebrand disease treatment is the replacement of the deficient protein (VWF)1

Quality: high molecular weight von Willebrand factor (HMW-VWF) multimers2

  • The clinical efficacy of a von Willebrand factor (VWF) concentrate is related to the quality of its multimers
  • HMW-VWF demonstrates increased hemostatic activity2
  • HMW-VWF is associated with
    — High specific activity2
    — VWF:ristocetin cofactor (VWF:RCo) activity
    — Collagen-binding activity
  • HMW-VWF is associated with shortened bleeding time3

Important Safety Information

Antihemophilic Factor/von Willebrand Factor Complex (Human), Dried, Pasteurized, Humate-P® is indicated in adult patients for treatment and prevention of bleeding in hemophilia A (classical hemophilia). Humate-P® is also in indicated in adult and pediatric patients with von Willebrand disease (VWD) for (1) treatment of spontaneous and trauma-induced bleeding episodes, and (2) prevention of excessive bleeding during and after surgery. This applies to patients with severe VWD, and patients with mild and moderate VWD for whom use of desmopressin is known or suspected to be inadequate.

Humate-P® is contraindicated in individuals with a history of anaphylactic or severe systemic response to antihemophilic factor or von Willebrand factor preparations or any of its components.

Thromboembolic events have been reported in VWD patients receiving coagulation factor replacement, especially in the setting of known risk factors for thrombosis. Caution should be exercised and antithrombotic measures considered.

Humate-P® is derived from human plasma. As with all plasma-derived products, the risk of transmission of infectious agents, including viruses and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent, cannot be completely eliminated.

Although few adverse reactions have been reported the most common are allergic-anaphylactic reactions, including urticaria, chest tightness, rash, pruritus, edema, shock, chills and fever, and hypervolemia. For patients undergoing surgery, the most common adverse reactions are postoperative wound or injection-site bleeding.
