About Paroxysmal Nocturnal Hemoglobinuria (PNH)
Paroxysmal nocturnal hemoglobinuria (PNH) is a serious ultra-rare blood disorder with devastating consequences. It is characterized by the destruction of red blood cells, which is also referred to as hemolysis. PNH occurs when the complement system—a part of the body’s immune system—over-responds, leading the body to attack its own red blood cells. PNH often goes unrecognized, with delays in diagnosis from one to more than five years. Patients with PNH may experience a range of symptoms, such as fatigue, difficulty swallowing, shortness of breath, abdominal pain, erectile dysfunction, dark-colored urine and anemia. The most devastating consequence of chronic hemolysis is the formation of blood clots, which can occur in blood vessels throughout the body, damage vital organs, and potentially lead to premature death. PNH can strike men and women of all races, backgrounds and ages without warning, with an average age of onset in the early 30s.
About Atypical Hemolytic Uremic Syndrome (aHUS)
Atypical HUS is an ultra-rare disease that can cause progressive injury to vital organs, primarily the kidneys, via damage to the walls of blood vessels and blood clots. aHUS occurs when the complement system—a part of the body’s immune system—over-responds, leading the body to attack its own healthy cells. aHUS can cause sudden organ failure or a slow loss of function over time—potentially resulting in the need for a transplant, and in some cases, death. aHUS affects both adults and children, and many patients present in critical condition, often requiring supportive care, including dialysis, in an intensive care unit. The prognosis of aHUS can be poor in many cases, so a timely and accurate diagnosis—in addition to treatment—is critical to improving patient outcomes. Available tests can help distinguish aHUS from other hemolytic diseases with similar symptoms.
About ULTOMIRIS® (ravulizumab‑cwvz)
ULTOMIRIS® (ravulizumab-cwvz) is the first and only long-acting C5 complement inhibitor. The medication works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system. When activated in an uncontrolled manner, the complement cascade over-responds, leading the body to attack its own healthy cells. ULTOMIRIS is administered intravenously every eight weeks or every four weeks for pediatric patients less than 20 kg, following a loading dose. ULTOMIRIS is approved in
About SOLIRIS® (eculizumab)
SOLIRIS® (eculizumab) is a first-in-class C5 complement inhibitor. The medication works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system. When activated in an uncontrolled manner, the terminal complement cascade over-responds, leading the body to attack its own healthy cells. SOLIRIS is administered intravenously every two weeks, following an introductory dosing period. In many countries around the world, SOLIRIS is approved to treat paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), adults with generalized myasthenia gravis (gMG) who are acetylcholine receptor (AchR) antibody positive and/or adults with neuromyelitis optica spectrum disorder (NMOSD) who are anti-aquaporin-4 (AQP4) antibody positive. SOLIRIS is not indicated for the treatment of patients with Shiga-toxin E. coli-related hemolytic uremic syndrome (STEC-HUS).

INDICATIONS & IMPORTANT SAFETY INFORMATION FOR ULTOMIRIS® (ravulizumab-cwvz) AND SOLIRIS® (eculizumab)
ULTOMIRIS and SOLIRIS are prescription medicines called monoclonal antibodies. ULTOMIRIS and SOLIRIS are used to treat adults with a disease called Paroxysmal Nocturnal Hemoglobinuria (PNH). ULTOMIRIS and SOLIRIS are also used to treat adults and children with a disease called atypical Hemolytic Uremic Syndrome (aHUS). Neither ULTOMIRIS nor SOLIRIS is for use in treating people with Shiga toxin E. coli related hemolytic uremic syndrome (STEC-HUS).
In addition, SOLIRIS is used to treat adults with a disease called generalized myasthenia gravis (gMG) who are anti-acetylcholine receptor (AChR) antibody positive. SOLIRIS is also used to treat adults with a disease called neuromyelitis optica spectrum disorder (NMOSD) who are anti-aquaporin-4 (AQP4) antibody positive.
It is not known if ULTOMIRIS is safe and effective in children with PNH or in children younger than one month of age in aHUS. It is also not known if SOLIRIS is safe and effective in children with PNH, gMG, or NMOSD.
IMPORTANT SAFETY INFORMATION
ULTOMIRIS and SOLIRIS are medicines that affect the immune system. These medicines can lower the ability of the immune system to fight infections. Both medicines increase 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 two weeks before the first dose of ULTOMIRIS or SOLIRIS if the patient has not already had this vaccine. If the patient’s doctor decided that urgent treatment is needed, meningococcal vaccination should be administered as soon as possible. If the patient has not been vaccinated and therapy must be initiated immediately, two weeks of antibiotics should also be administered with the vaccinations. If the patient had a meningococcal vaccine in the past, additional vaccination might be needed before starting ULTOMIRIS or SOLIRIS. Patients should ask their doctor if an additional meningococcal vaccination is needed. Meningococcal vaccines reduce the risk of meningococcal infection but do not prevent all meningococcal infections. Patients should be instructed to call their 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 and fever, headache with a stiff neck or stiff back, fever, fever and a rash, confusion, muscle aches with flu-like symptoms, and eyes sensitive to light. The doctor will provide a Patient Safety Card about the risk of meningococcal infection. This card must be carried at all times during treatment and for 8 months after the last ULTOMIRIS dose or 3 months after the last SOLIRIS dose.
Before a patient can receive ULTOMIRIS or SOLIRIS, their doctor must: enroll in the corresponding ULTOMIRIS REMS or SOLIRIS REMS program; counsel the patient about the risk of meningococcal infection; give the patient information and a Patient Safety Card about the symptoms and risk of meningococcal infection (as discussed above); and make sure that the patient is vaccinated with a meningococcal vaccine.
ULTOMIRIS and SOLIRIS may also increase the risk of other types of serious infections. Patients should talk to their doctor right away if they have any new signs or symptoms of infection.
Patients must not receive ULTOMIRIS or SOLIRIS if they have a meningococcal infection, or if they have not been vaccinated against meningococcal infection, unless their doctor decides that urgent treatment is needed.
Before a patient receives ULTOMIRIS or SOLIRIS, they should tell their doctor about all of their medical conditions, including if they: have an infection or fever, are pregnant or plan to become pregnant, and are breastfeeding or plan to breastfeed. It is not known if ULTOMIRIS or SOLIRIS will harm an unborn baby or if these medicines pass into the breast milk.
Patients should tell their doctor about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. ULTOMIRIS and SOLIRIS can affect how other medicines work, causing side effects.
For patients with PNH, the doctor will need to monitor the patient closely for at least 16 weeks after stopping ULTOMIRIS or 8 weeks after stopping SOLIRIS. Stopping treatment with these medicines may cause breakdown of the red blood cells due to PNH. Symptoms or problems that can happen due to red blood cell breakdown include: a drop in red blood cell count, tiredness, blood in the urine, stomach-area (abdomen) pain, shortness of breath, blood clots, trouble swallowing, and erectile dysfunction (ED) in males.
For patients with aHUS, the doctor will need to monitor closely during and for at least 12 months after stopping ULTOMIRIS, or 12 weeks after stopping SOLIRIS, for signs of worsening aHUS symptoms or problems related to abnormal clotting and breakdown of red blood cells called thrombotic microangiopathy (TMA). Symptoms or problems that can happen with TMA may include: confusion or loss of consciousness, seizures, chest pain (angina), difficulty breathing and blood clots or stroke.
ULTOMIRIS can cause serious side effects including infusion reactions. Symptoms of an infusion reaction with ULTOMIRIS may include lower back pain, pain with the infusion, feeling faint or discomfort in the arms or legs. Patients should tell their doctor or nurse right away if they develop these symptoms, or any other symptoms during their ULTOMIRIS infusion that may mean they are 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.
The most common side effects of ULTOMIRIS in people treated for PNH are upper respiratory infection and headache. The most common side effects of ULTOMIRIS in people with aHUS are upper respiratory infection, diarrhea, nausea, vomiting, headache, high blood pressure and fever.
SOLIRIS can cause serious side effects including serious allergic reactions. Serious allergic reactions can happen during the SOLIRIS infusion. Patients should tell their doctor or nurse right away if they get 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 a patient 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. The most common side effects in people with NMOSD treated with SOLIRIS include: common cold (upper respiratory infection); pain or swelling of the nose or throat (nasopharyngitis); diarrhea; back pain; dizziness; flu like symptoms (influenza) including fever, headache, tiredness, cough, sore throat, and body aches; joint pain (arthralgia); throat irritation (pharyngitis), and bruising (contusion).
Tell your doctor about any side effect that bothers you or that does not go away. These are not all the possible side effects of ULTOMIRIS or SOLIRIS. For more information, ask your doctor or pharmacist. Call your doctor right away if you miss an ULTOMIRIS or SOLIRIS infusion or for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
