Background and Date of Approval of Eculizumab
Eculizumab is a monoclonal antibody used to treat rare blood and kidney disorders. It was first approved by the US FDA in March 2007 for paroxysmal nocturnal hemoglobinuria (PNH) and later for other conditions such as atypical hemolytic uremic syndrome (aHUS) and generalized myasthenia gravis (gMG).
Uses
Eculizumab is approved for the following conditions:
-
Paroxysmal Nocturnal Hemoglobinuria (PNH): Prevents destruction of red blood cells and reduces anaemia and risk of blood clots.
-
Atypical Hemolytic Uremic Syndrome (aHUS): Helps protect kidneys and prevents organ damage caused by uncontrolled complement activation.
-
Generalised Myasthenia Gravis (gMG): Reduces muscle weakness and improves daily functioning in patients with antibodies against acetylcholine receptors.
-
Prevention of Complement-Mediated Organ Damage: Used in conditions where overactivation of the complement system can harm organs.
-
Other Rare Complement-Mediated Disorders: May be prescribed for other conditions as determined by a physician.
How is Eculizumab administered?
Eculizumab is given intravenously (IV) by a healthcare professional in a hospital or clinic. Your doctor will determine the dose and frequency based on your condition. Infusions are typically administered every 2–4 weeks. You will be closely monitored for side effects during and after the infusion. Do not self-administer this medicine at home.
