Pharmacology

Indication

Vonicog alfa is indicated for the on-demand treatment and control of bleeding episodes in adults previously diagnosed with von Willebrand disease.8 Vonicog alfa contains only the vWF and thus, its administration offers the flexibility to administer the coagulation factor VIII if needed. The von Willebrand disease is an inherited disorder characterized by the deficiency or misfunction of the von Willebrand factor (vWF). Due to this deficiency, the blood cannot clot properly and the patients that present this disease are prone to prolonged or excessive bleeding. There are three types of this disease, and type 3 is an autosomal recessive inherited disorder marked by very low or absent levels of vWF.9

Pharmacodynamics

Vonicog alfa does not present a risk of transmission of blood-borne pathogens as it is a recombinant, plasma- and albumin-free protein. The two first clinical trials showed an effective reduction of bleeding episodes in different sites of the body. This effect was observed even after the first infusion in 81% of the cases.3

Mechanism of action

Von Willebrand factor (vWF) is an important piece of the blood coagulation cascade and it acts by stabilizing the coagulation factor VIII. It also binds to collagen and platelets in blood vessel walls which helps with the formation of a platelet plug during clotting process. The presence of different mutations in vWF causes a common bleeding disorder named von Willebrand disease.6 The bleeding episodes were usually treated with plasma-derived vWF/factor VIII concentrates which required high doses and long treatment duration. The use of vonicog alfa allows a separate administration of vWF without the presence of the Factor VIII. This separate dosing allows the personalization of the dosage according to the patient's needs.2 On the same note, the plasma-derived vWF concentrates variably lack ULM due to an in vivo exposure to plasma ADAMTS13 and granulocyte elastases. Vonicog alfa can be delivered as an unaltered vWF and it functions as a replacement of vWF. Thus, it mediates platelet adhesion and aggregation as well as stabilization of the procoagulant factor VIII.3

Absorption

In pharmacokinetic studies, the Cmax, AUC and mean residence time of vonicog alfa are reported to be 90.7 mcg, 1877 h.U/dL and 29.8 hours, respectively.3

Volume of distribution

In phase 3 clinical trials, the volume of distribution of vonicog alfa is reported to be of 0.80 L.3

Protein binding

Vonicog alfa presents a very high plasma protein binding as its main function is performed in the blood.3

Metabolism

The endogenous regulator of the vWF is ADAMTS13. The interaction between these two proteins results in the proteolysis of vWF. This proteolysis occurs primarily in the cleavage site at the domain A2 which is a target domain for ADAMTS13.5

Route of elimination

The majority of vonicog alfa is targeted to the liver and spleen which indicates an active regulatory elimination mechanism. It seems to be uptaken mainly by macrophages.4

Half-life

Clinical trials have shown a terminal half-life of 21.9 hours for vonicog alfa which can be modified by the coadministration of the factor VIII.3

Clearance

In phase 3 clinical trials, the clearance rate of vonicog alfa is reported to be of 0.29 dL/kg/h.3
