Danicopan, sold under the brand name Voydeya, is a medication used for the treatment of paroxysmal nocturnal hemoglobinuria. It is a complement inhibitor which reversibly binds to factor D to prevent alternative pathway-mediated hemolysis and deposition of complement C3 proteins on red blood cells. The most common side effects include fever, headache, increased levels of liver enzymes (a sign ...
The sucrose lysis test is a diagnostic laboratory test used for diagnosing paroxysmal nocturnal hemoglobinuria (PNH), as well as for hypoplastic anemias and any hemolytic anemia with an unclear cause. [1] The test works by using sucrose, which creates a low ionic strength environment that allows complement to bind to red blood cells. [1]
Crovalimab is the subject of five phase III studies for paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome (aHUS). It is also being investigated for the treatment of sickle cell disease and other conditions.
Ravulizumab, sold under the brand name Ultomiris, is a humanized monoclonal antibody complement inhibitor medication designed for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome. It is designed to bind to and prevent the activation of Complement component 5 (C5). [8] [7]
The drug crovalimab, branded as PiaSky, is a monthly under-the-skin or intravenous treatment for paroxysmal nocturnal hemoglobinuria (PNH). PNH is a disorder in which red blood cells break apart ...
Pegcetacoplan is the first treatment for paroxysmal nocturnal hemoglobinuria that binds to and inhibits complement protein C3. [9] Pegcetacoplan was approved for medical use in the United States in May 2021. [9] The US Food and Drug Administration (FDA) considers it to be a first-in-class medication. [16]
Because DAF is a GPI-anchored protein, its expression is reduced in persons with mutations that reduce GPI levels such as those with paroxysmal nocturnal hemoglobinuria (PNH). In PNH disorder, red blood cells with very low levels of DAF and CD59 undergo complement-mediated hemolysis. Symptoms include low red blood cell count (anemia), fatigue ...
Iptacopan, sold under the brand name Fabhalta, is a medication used for the treatment of paroxysmal nocturnal hemoglobinuria (PNH). [4] It is a complement factor B inhibitor that was developed by Novartis. [4] It is taken by mouth. [4]
