Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. Symptoms may include large bruises, fever, weakness, shortness of breath, confusion, and headache. Repeated episodes may occur.
Clopidogrel, sold under the brand name Plavix among others, is an antiplatelet medication used to reduce the risk of heart disease and stroke in those at high risk. It is also used together with aspirin in heart attacks and following the placement of a coronary artery stent. It is taken by mouth. Its effect starts about two hours after intake and lasts for five days.
Fabry disease, also known as Anderson–Fabry disease, is a rare genetic disease that can affect many parts of the body, including the kidneys, heart, brain, and skin. Fabry disease is one of a group of conditions known as lysosomal storage diseases. The genetic mutation that causes Fabry disease interferes with the function of an enzyme that processes biomolecules known as sphingolipids, leading to these substances building up in the walls of blood vessels and other organs. It is inherited in an X-linked manner.
ADAMTS13 —also known as von Willebrand factor-cleaving protease (VWFCP)—is a zinc-containing metalloprotease enzyme that cleaves von Willebrand factor (vWf), a large protein involved in blood clotting. It is secreted into the blood and degrades large vWf multimers, decreasing their activity, hence ADAMTS13 acts to reduce thrombus formation.
Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. It is used to treat conditions in which there are low blood clotting factors or low levels of other blood proteins. It may also be used as the replacement fluid in plasma exchange. Using ABO compatible plasma, while not required, may be recommended. Use as a volume expander is not recommended. It is administered by slow injection into a vein.
Thrombotic microangiopathy (TMA) is a pathology that results in thrombosis in capillaries and arterioles, due to an endothelial injury. It may be seen in association with thrombocytopenia, anemia, purpura and kidney failure.
Maribavir, sold under the brand name Livtencity, is an antiviral medication that is used to treat post-transplant cytomegalovirus (CMV). Maribavir is a cytomegalovirus pUL97 kinase inhibitor that works by preventing the activity of human cytomegalovirus enzyme pUL97, thus blocking virus replication.
Recombinant factor VIIa (rfVIIa) is a form of blood factor VII that has been manufactured via recombinant technology. It is administered via an injection into a vein. It is used to treat bleeding episodes in people who have acquired haemophilia, among other indications. There are several disimilar forms, and biosimilars for each. All forms are activated.
Caplacizumab is a bivalent single-domain antibody (VHH) designed for the treatment of thrombotic thrombocytopenic purpura (TTP) and thrombosis.
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.
Upshaw–Schulman syndrome (USS) is the recessively inherited form of thrombotic thrombocytopenic purpura (TTP), a rare and complex blood coagulation disease. USS is caused by the absence of the ADAMTS13 protease resulting in the persistence of ultra large von Willebrand factor multimers (ULVWF), causing episodes of acute thrombotic microangiopathy with disseminated multiple small vessel obstructions. These obstructions deprive downstream tissues from blood and oxygen, which can result in tissue damage and death. The presentation of an acute USS episode is variable but usually associated with thrombocytopenia, microangiopathic hemolytic anemia (MAHA) with schistocytes on the peripheral blood smear, fever and signs of ischemic organ damage in the brain, kidney and heart.
Sebelipase alfa, sold under the brand name Kanuma, is a recombinant form of the enzyme lysosomal acid lipase (LAL) that is used as a medication for the treatment of lysosomal acid lipase deficiency (LAL-D). It is administered via intraveneous infusion. It was approved for medical use in the European Union and in the United States in 2015.
Vestronidase alfa, sold under brand name Mepsevii, is a drug for the treatment of Sly syndrome. It is a recombinant form of the human enzyme beta-glucuronidase. It was approved in the United States in November 2017, to treat children and adults with an inherited metabolic condition called mucopolysaccharidosis type VII, also known as Sly syndrome. MPS VII is an extremely rare, progressive condition that affects most tissues and organs.
Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder characterized by thrombocytopenia and microangiopathic hemolytic anemia accompanied by variable neurological dysfunction, kidney failure, and fever. It is caused by severely reduced activity of the von Willebrand factor-cleaving protease ADAMTS13. Hereditary TTP, caused by ADAMTS13 gene mutations, is much less common.
Velmanase alfa, sold under the brand name Lamzede, is a medication used for the treatment of alpha-mannosidosis. Velmanase alfa is a recombinant human lysosomal alpha-mannosidase.
Damoctocog alfa pegol, sold under the brand name Jivi is a recombinant DNA-derived, Factor VIII concentrate 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.
Avalglucosidase alfa, sold under the brand name Nexviazyme, is an enzyme replacement therapy medication used for the treatment of glycogen storage disease type II.
Olipudase alfa, sold under the brand name Xenpozyme, is a medication used for the treatment of non-central nervous system (CNS) manifestations of acid sphingomyelinase deficiency type A/B or type B.
Cipaglucosidase alfa, sold under the brand name Pombiliti, and used in combination with miglustat, is a medication used for the treatment of glycogen storage disease type II. Cipaglucosidase alfa is a recombinant human acid α-glucosidase enzyme replacement therapy that provides an exogenous source of acid α-glucosidase.
