Factor IX (Recombinant)

Factor IX (Recombinant) Uses, Dosage, Side Effects, Food Interaction and all others data.

Recombinant Coagulation Factor IX is a purified Factor IX glycoprotein produced by recombinant DNA technology. It has a primary amino acid sequence that is identical to the Ala148 allelic form of human factor IX, and has structural and functional characteristics similar to those of endogenous factor IX. It is not derived from human blood (unlike human Factor IX complex), and is instead produced by a genetically engineered Chinese hamster ovary (CHO) cell line that secretes recombinant Factor IX into cell medium that is then processed and purified for use as a pharmaceutical agent.

Recombinant Factor IX is indicated for the control and prevention of bleeding episodes in adult and pediatric patients with congenital factor IX deficiency (Hemophilia B).

Binds vitamin K and factor VIIIa. Cleaves the Arg-Ile bond in factor X to form active factor Xa. Plays a key role in blood coagulation and clotting. Injections of factor IX are used to treat hemophilia B, which is sometimes called Christmas disease. AlphaNine is injected to increase plasma levels of Factor IX and can temporarily correct this coagulation defect. The activated partial thromboplastin time (aPTT) is prolonged in people with hemophilia B. Treatment with factor IX concentrate may normalize the aPTT by temporarily replacing the factor IX. The administration of BeneFIX increases plasma levels of factor IX, and can temporarily correct the coagulation defect in these patients.

Factor IX (Recombinant) is a form of recombinant human coagulation Factor IX used to treat hemophilia B.

For treatment of hemophilia (Christmas disease).

Factor IX (Recombinant) is also used to associated treatment for these conditions: Hemophilia B

How Factor IX (Recombinant) works

Coagulation Factor IX is an important protein in the process of hemostasis and normal blood clotting as it plays a key role within the coagulation cascade. It is located within the blood plasma as a zymogen, an antecedent to enzymatic function, in its inactivated state. Factor IX is dependent on the presence of Vitamin K, and is activated to a serine protease by the function of Coagulation Factor XIa. Factor XIa cleaves the peptide bond associated with protein activation in Factor IX, leaving Factor IX with two exposed chains, a light chain and a heavy chain. These two chains are held together by several disulfide bonds that reinforce the structure of Factor IX's activated form. After being activated, Factor IX forms a complex with calcium ions, membrane phospholipids and Coagulation Factor VIII to activate Coagulation Factor X. The activation of Factor X then performs a similarly integral step in the blood coagulation cascade. The ultimate result of phenotypically normal coagulation factors is the creation of platelets for normal blood clotting.
