BOSTON--(BUSINESS WIRE)--Alexion Pharmaceuticals, Inc. (NASDAQ:ALXN) today announced that Japan’s Ministry of Health, Labour and Welfare (MHLW) has approved ULTOMIRIS® (ravulizumab), the first and only long-acting C5 complement inhibitor administered every eight weeks, for the treatment of adult patients with paroxysmal nocturnal hemoglobinuria (PNH).
PNH is an ultra-rare and severe disease that, when left untreated, may cause a wide range of debilitating symptoms and complications, including thrombosis. Thrombosis occurs when a blood clot presents inside a blood vessel, and slows or blocks the flow of blood through the circulatory system. Serious cases of thrombosis can occur throughout the body and result in organ damage, stroke, heart attack, and potentially premature death.1–8
“As a physician, I am pleased to have a new medication for patients in Japan facing the burden of living with PNH—both for people naive to anti-complement therapy and those that are already on SOLIRIS seeking to make a change without interruption,” said Jun-ichi Nishimura, M.D., Ph.D. Assistant Professor, Department of Hematology and Oncology, Osaka University Graduate School of Medicine, Japan. “When PNH is not treated, the consequences can be serious.”
PNH can strike men and women of all races, backgrounds and ages without warning, with an average age of onset in the early 30s.1,9 PNH often goes unrecognized, with delays in diagnosis ranging from one to more than five years.10
The Ministry’s approval is based on comprehensive results from two Phase 3 studies, which were published in Blood.11,12 In these studies, which included 441 patients who had either never been treated with a complement inhibitor before, or who had been stable on SOLIRIS, the efficacy of ULTOMIRIS administered every eight weeks was non-inferior to the efficacy of SOLIRIS administered every two weeks on all 11 endpoints. The safety profile of ULTOMIRIS was similar to that of SOLIRIS. Additional data showed that ULTOMIRIS provided immediate and complete C5 inhibition that was sustained for eight weeks13 and that ULTOMIRIS eliminated breakthrough hemolysis associated with incomplete C5 inhibition.14 The entire clinical development program for ULTOMIRIS to date represents more than 800 patient years of experience.
“Immediate and complete C5 inhibition with ULTOMIRIS can provide meaningful benefits for patients and their families,” said John Orloff, M.D., Executive Vice President and Head of Research & Development at Alexion. “Based on the totality of our compelling data from the largest Phase 3 program ever conducted in PNH, we believe ULTOMIRIS has the potential to become the new standard of care for patients with PNH in Japan. We would like to express our deep gratitude to the patients and investigators in Japan who supported this study with their participation.”
About Paroxysmal Nocturnal Hemoglobinuria (PNH)
Paroxysmal nocturnal hemoglobinuria (PNH) is a chronic, progressive, debilitating and life-threatening ultra-rare blood disorder characterized by hemolysis (destruction of red blood cells) that is mediated by an uncontrolled activation of the complement system, a component of the body’s immune system.1,2,15 PNH can strike men and women of all races, backgrounds and ages without warning, with an average age of onset in the early 30s.1,9 PNH often goes unrecognized, with delays in diagnosis ranging from one to more than five years.10 Patients with PNH may experience a wide range of signs and symptoms, such as fatigue, difficulty swallowing, shortness of breath, abdominal pain, erectile dysfunction, dark-colored urine and anemia.3–5,7,8,11,15 The most devastating consequence of chronic hemolysis is thrombosis, which can occur in blood vessels throughout the body, damage vital organs and cause premature death.16 The first thrombotic event can be fatal.1,9,17 Despite historical supportive care, including transfusion and anticoagulation management, 20 to 35 percent of patients with PNH die within five to 10 years of diagnosis.18,19 Patients with certain types of hemolytic anemia, bone marrow disorders and unexplained venous or arterial thrombosis are at increased risk of PNH.15,20–24
ULTOMIRIS (ravulizumab), the first and only long-acting C5 inhibitor administered every eight weeks, is approved in the U.S. and Japan 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). In Phase 3 clinical studies in complement inhibitor-naïve patients with PNH11 and patients with PNH who had been stable on SOLIRIS® (eculizumab),12 intravenous treatment with ULTOMIRIS every eight weeks demonstrated non-inferiority to intravenous treatment with SOLIRIS every two weeks on all 11 endpoints.
The Phase 3 study of ULTOMIRIS, administered intravenously every eight weeks in adult patients with aHUS, met its primary objective. Alexion has submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for approval of ULTOMIRIS as a treatment for patients with aHUS and plans to submit similar applications in the EU and Japan later in 2019. 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, aHUS and gMG.
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 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 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.

SOLIRIS may also increase the risk of other types of serious infections. If one’s child is treated with SOLIRIS, make sure that the child receives vaccinations against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib). Certain people may be at risk of serious infections with gonorrhea. Talk to the doctor about whether one is at risk for gonorrhea infection, about gonorrhea prevention, and regular testing. Certain fungal infections (Aspergillus) may also happen if one takes SOLIRIS and has a weak immune system or a low white blood cell count.
Before one receives SOLIRIS, 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 SOLIRIS will harm an unborn baby. It is not known if SOLIRIS passes into the breast milk.
Tell the doctor about all the medicines one takes, including prescription and over-the-counter medicines, vitamins, and herbal supplements. SOLIRIS and other medicines can affect each other causing side effects.
It is important that one: has all recommended vaccinations before starting SOLIRIS, receives 2 weeks of antibiotics if one immediately starts SOLIRIS, and stays up-to-date with all recommended vaccinations during treatment with SOLIRIS. 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 has PNH, the doctor will need to monitor closely for at least 8 weeks after stopping SOLIRIS. Stopping treatment with SOLIRIS 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, drop in the platelet counts, confusion, kidney problems, blood clots, difficulty breathing, and chest pain.
If one has aHUS, the doctor will need to monitor closely for at least 12 weeks after stopping SOLIRIS for signs of worsening aHUS symptoms or problems related to abnormal clotting (thrombotic microangiopathy). Symptoms or problems that can happen with abnormal clotting may include: stroke, confusion, seizure, chest pain (angina), difficulty breathing, kidney problems, swellings in arms or legs and a drop in platelet count.
SOLIRIS can cause serious side effects including serious allergic reactions. Serious allergic reactions can happen during one’s SOLIRIS infusion. Tell the doctor or nurse right away if one gets any of these symptoms during the SOLIRIS infusion: chest pain, trouble breathing or shortness of breath, swelling of the face, tongue, or throat, and feeling faint or pass out. If one has an allergic reaction to SOLIRIS, the doctor may need to infuse SOLIRIS more slowly, or stop SOLIRIS. The most common side effects in people with PNH treated with SOLIRIS include: headache, pain or swelling of the nose or throat (nasopharyngitis), back pain, and nausea. The most common side effects in people with aHUS treated with SOLIRIS include: headache, diarrhea, high blood pressure (hypertension), common cold (upper respiratory infection), stomach-area (abdominal pain), vomiting, pain or swelling of the nose or throat (nasopharyngitis), low red blood cell count (anemia), cough, swelling of legs or feet (peripheral edema), nausea, urinary tract infections, and fever. The most common side effects in people with gMG treated with SOLIRIS include: muscle and joint (musculoskeletal) pain.
