Haemophilia, or hemophilia, is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding. This results in people bleeding for a longer time after an injury, easy bruising, and an increased risk of bleeding inside joints or the brain. Those with a mild case of the disease may have symptoms only after an accident or during surgery. Bleeding into a joint can result in permanent damage while bleeding in the brain can result in long term headaches, seizures, or a decreased level of consciousness.
Haemophilia A is a blood clotting disorder caused by a genetic deficiency in clotting factor VIII, thereby resulting in significant susceptibility to bleeding, both internally and externally. This condition occurs almost exclusively is in males born to carrier mothers due to X-linked recessive inheritance. Nevertheless, rare isolated cases do emerge from de novo (spontaneous) mutations.
Haemophilia B, also spelled hemophilia B, is a blood clotting disorder causing easy bruising and bleeding due to an inherited mutation of the gene for factor IX, and resulting in a deficiency of factor IX. It is less common than factor VIII deficiency.
Coagulation factor VII is one of the proteins that causes blood to clot in the coagulation cascade, and in humans is coded for by the gene F7. It is an enzyme of the serine protease class. Once bound to tissue factor released from damaged tissues, it is converted to factor VIIa, which in turn activates factor IX and factor X.
Prothrombin complex concentrate (PCC), also known as factor IX complex, sold under the brand name Kcentra among others, is a combination medication made up of blood clotting factors II, IX, and X. Some versions also contain factor VII. It is used to treat and prevent bleeding in hemophilia B if pure factor IX is not available. It may also be used for reversal of warfarin therapy. It is given by slow injection into a vein.
Factor VIII is a medication used to treat and prevent bleeding in people with hemophilia A and other causes of low factor VIII. Certain preparations may also be used in those with von Willebrand's disease. It is given by slow injection into a vein.
CSL Behring is a biopharmaceutical company, manufacturing plasma-derived, and recombination therapeutic products. The company is a combination of Behringwerke, founded in 1904 in Marburg, Germany by Emil von Behring, and the Commonwealth Serum Laboratories (CSL), established in Australia in 1916 to provide vaccines to the people of Australia, as well as other companies acquired since 2004
Swedish Orphan Biovitrum AB is an international biopharmaceutical company dedicated to treatments in the areas of haematology, immunology and specialty care, based in Stockholm, Sweden.
Octapharma AG, founded in 1983, is a family-owned pharmaceutical company based in Switzerland. It bills itself as "one of the largest human protein manufacturers in the world, developing and producing human proteins from human plasma and human cell lines."
Moroctocog alfa is a recombinant antihemophilic factor genetically engineered from Chinese hamster ovary (CHO) cell line. Chemically it is a glycoprotein. It is manufactured by Genetics Institute, Inc. and used to control and prevent hemorrhagic bleeding and prophylaxis associated with surgery or to reduce the number of spontaneous bleeding episodes in patients with hemophilia A. It is partially a recombinant coagulation factor VIII since it has an amino acid sequence which compares to the 90 + 80 kDa form of factor VIII (BDDrFVIII). It also has posttranslational modifications which are similar to those of the plasma-derived molecule. It can not prevent hemorrhagic bleeding associated with von Willebrand's disease since it is not a von Willebrand factor.
Recombinant factor VIIa also known as eptacog alfa (INN), and sold under the brand name Novoseven among others, is a form of blood factor VII that has been manufactured via recombinant technology. It is administered via an injection into a vein.
Jeanne Marie Lusher, M.D. was an American physician, pediatric hematologist/oncologist, and a researcher in the field of bleeding disorders of childhood, and has served as the director of Hemostasis Program at the Children's Hospital of Michigan until her retirement on June 28, 2013.
Catridecacog, sold under the brand name Tretten in the US and NovoThirteen in the EU) is a class of recombinant factor XIII A-subunit based biopharmaceutical medicine, indicated in patients with a rare clotting disorder, congenital factor XIII A-subunit deficiency, which is a kind of Factor XIII deficiency. The medication prevents bleeding in patients with this condition, and has been approved by the U.S. Food and Drug Administration (FDA) for this use in the US in 2014. It was brought to market by Novo Nordisk.
Turoctocog alfa is a recombinant antihemophilic factor VIII used for the treatment of and prophylaxis of bleeding patients with haemophilia A. It is marketed by Novo Nordisk. It was approved in the United States, the European Union, and Japan in 2013.
Acquired haemophilia A (AHA) is a rare but potentially life-threatening bleeding disorder characterized by autoantibodies directed against coagulation factor VIII. These autoantibodies constitute the most common spontaneous inhibitor to any coagulation factor and may induce spontaneous bleeding in patients with no previous history of a bleeding disorder.
Susoctocog alfa, sold under the brand name Obizur, is a medication used for the treatment of bleeding episodes in adults with acquired haemophilia, a bleeding disorder caused by the spontaneous development of antibodies that inactivate factor VIII.
Efmoroctocog alfa, sold under the brand name Elocta among others, is a medication for the treatment and prophylaxis of bleeding in people with hemophilia A. Efmoroctocog alfa is a recombinant human coagulation factor VIII, Fc fusion protein (rFVIIIFc). It is produced by recombinant DNA technology in a human embryonic kidney (HEK) cell line.
Damoctocog alfa pegol, sold under the brand name Jivi is a recombinant DNA-derived, Factor VIII concentrate medication used to treat hemophilia A.
Valoctocogene roxaparvovec, sold under the brand name Roctavian, is a gene therapy used for the treatment of hemophilia A. It was developed by BioMarin Pharmaceutical. Valoctocogene roxaparvovec is made of a virus (AAV5) that has been modified to contain the gene for factor VIII, which is lacking in people with hemophilia A. It is an adeno-associated virus vector-based gene therapy. It is given by intravenous infusion.
Etranacogene dezaparvovec, sold under the brand name Hemgenix is a gene therapy used for the treatment of hemophilia B. Etranacogene dezaparvovec is an adeno-associated virus vector-based gene therapy which consists of a viral vector carrying a gene for clotting Factor IX. The gene is expressed in the liver to produce Factor IX protein, to increase blood levels of Factor IX and thereby limit bleeding episodes. Hemophilia B is a genetic bleeding disorder resulting from missing or insufficient levels of blood clotting Factor IX, a protein needed to produce blood clots to stop bleeding.
