BOSTON -- (EUREKALERT!) -- Alexion Pharmaceuticals, Inc. today announced the first conference presentation of the topline Phase 3 data for ULTOMIRIS® (ravulizumab), the first and only long-acting C5 complement inhibitor administered every eight weeks, in adult patients with atypical hemolytic syndrome (aHUS). The previously announced data will be presented at the Annual Congress of the European Renal Association - European Dialysis and Transplant Association (ERA-EDTA), taking place June 13-16, 2019 in Budapest, Hungary:
Efficacy and safety of the long-acting complement C5 inhibitor ravulizumab in adult patients with atypical hemolytic uremic syndrome - Symposium 38, Regular Presentation, June 16, 2019, 09:30 a.m.1
Atypical HUS is a severe and chronic ultra-rare disease that affects both adults and children and can cause progressive and irreversible damage to vital organs, predominantly the kidneys, and lead to kidney failure (requiring dialysis or transplant) and premature death. The disease is characterized by inflammation and blood clotting in small blood vessels throughout the body, called thrombotic microangiopathy (TMA). This inflammation and blood clotting is mediated by chronic, uncontrolled activation of the complement system, which is part of the body's immune system.2,3,4,5,6
Early and careful diagnosis of aHUS is critical as many coexisting diseases and events are known or suspected to activate the complement cascade, and as patients may not necessarily present with the classic TMA triad of thrombocytopenia, hemolytic anemia and renal impairment,7 or may have less severe renal involvement.8 Available tests can help distinguish aHUS from other hemolytic diseases with similar symptoms such as HUS caused by Shiga toxin-producing Escherichia coli (STEC-HUS) and thrombotic thrombocytopenic purpura (TTP).6
Alexion submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for the approval of ULTOMIRIS in TMA, including aHUS, in April 2019 and plans to submit similar applications to the European Medicines Agency (EMA) and Pharmaceuticals and Medical Devices Agency (PMDA) in Japan later this year.
ULTOMIRIS (ravulizumab), the first and only long-acting C5 inhibitor administered every eight weeks, is approved in the U.S. as a treatment for adults with paroxysmal nocturnal hemoglobinuria (PNH). ULTOMIRIS works by inhibiting the C5 protein in the terminal complement cascade, a part of the body's immune system. The terminal complement cascade, when activated in an uncontrolled manner, plays a role in severe ultra-rare disorders like PNH, atypical hemolytic uremic syndrome (aHUS), anti-acetylcholine receptor (AchR) antibody-positive myasthenia gravis (MG) and anti-aquaporin-4 (AQP4) auto-antibody-positive neuromyelitis optica spectrum disorder (NMOSD). Regulatory authorities in the European Union (EU) and Japan are reviewing applications for the approval of ULTOMIRIS as a treatment for adult patients and patients with PNH, respectively.
ULTOMIRIS is also currently being evaluated in a Phase 3 clinical study in children and adolescents with aHUS, administered intravenously every eight weeks. Alexion has initiated a Phase 3 study of ULTOMIRIS, intravenously administered every eight weeks, as a potential treatment for patients with generalized MG (gMG), and is planning to initiate a Phase 3 in patients with NMOSD. In addition, Alexion has initiated Phase 3 studies of ULTOMIRIS delivered subcutaneously once per week as a potential treatment for patients with PNH and aHUS.
ULTOMIRIS has received Orphan Drug Designation (ODD) for the treatment of patients with PNH in the U.S. and Japan and for the subcutaneous treatment of patients with aHUS in the U.S.
U.S. Indication of ULTOMIRIS®
ULTOMIRIS (ravulizumab-cwvz) is a prescription medicine called a monoclonal antibody. ULTOMIRIS is used to treat adults with a disease called paroxysmal nocturnal hemoglobinuria (PNH). It is not known if ULTOMIRIS is safe and effective in children.
U.S. Important Safety Information for ULTOMIRIS®
ULTOMIRIS (ravulizumab-cwvz) is a medicine that affects the immune system. ULTOMIRIS can lower the ability of the immune system to fight infections. ULTOMIRIS increases the chance of getting serious and life-threatening meningococcal infections. Meningococcal infections may quickly become life-threatening and cause death if not recognized and treated early.
Meningococcal vaccines must be received at least 2 weeks before the first dose of ULTOMIRIS if one has not already had this vaccine. If one's doctor decided that urgent treatment with ULTOMIRIS is needed, meningococcal vaccination should be administered as soon as possible. If one has not been vaccinated and ULTOMIRIS therapy must be initiated immediately, 2 weeks of antibiotics should also be administered with the vaccinations. If one had a meningococcal vaccine in the past, additional vaccination might be needed before starting ULTOMIRIS. Call one's doctor or get emergency medical care right away if any of these signs and symptoms of a meningococcal infection occur: headache with nausea or vomiting, headache with a stiff neck or stiff back, fever and a rash, muscle aches with flu-like symptoms, headache and fever, fever, confusion, and eyes sensitive to light.
ULTOMIRIS is only available through a program called the ULTOMIRIS REMS.
ULTOMIRIS may also increase the risk of other types of serious infections. People who take ULTOMIRIS may have an increased risk of getting infections caused by Streptococcus pneumoniae and Haemophilus influenzae. Certain people may also have an increased risk of gonorrhea infection. To find out if one is at risk for gonorrhea infection, about gonorrhea prevention, and regular testing, talk to the healthcare provider. Call the healthcare provider right away if one has any new signs or symptoms of infection.
Before one receives ULTOMIRIS, tell the doctor about all of the medical conditions, including if one: has an infection or fever, is pregnant or plans to become pregnant, and is breastfeeding or plans to breastfeed. It is not known if ULTOMIRIS will harm an unborn baby. It is not known if ULTOMIRIS passes into the breast milk. One should not breast feed during treatment and for 8 months after one's final dose of ULTOMIRIS.
Tell the doctor about all the medicines one takes, including prescription and over-the-counter medicines, vitamins, and herbal supplements. ULTOMIRIS and other medicines can affect each other causing side effects. Know the medications one takes and the vaccines one receives. Keep a list of them to show the doctor and pharmacist when one gets a new medicine.
If one stops receiving ULTOMIRIS, the doctor will need to monitor closely for at least 16 weeks after one stops ULTOMIRIS. Stopping ULTOMIRIS may cause breakdown of the red blood cells due to PNH. Symptoms or problems that can happen due to red blood cell breakdown include: drop in the number of the red blood cell count, tiredness, blood in the urine, stomach-area (abdomen) pain, blood clots, shortness of breath, trouble swallowing, and erectile dysfunction (ED) in males.
ULTOMIRIS can cause serious side effects including infusion reactions. Infusion reactions may happen during one's ULTOMIRIS infusion. Symptoms of an infusion reaction with ULTOMIRIS may include lower back pain, pain with the infusion, or feeling faint. Tell the doctor or nurse right away if these symptoms develop, or any other symptoms during the ULTOMIRIS infusion that may mean one is having a serious infusion reaction, including: chest pain, trouble breathing or shortness of breath, swelling of the face, tongue, or throat, and feel faint or pass out. One's doctor will treat the symptoms as needed. The most common side effects of ULTOMIRIS are upper respiratory infection and headache.
