SOLIRIS is approved in the EU for the treatment of NMOSD in adult patients who are anti-AQP4 antibody positive with a relapsing course of the disease. In the U.S., SOLIRIS is approved for the treatment of adults with NMOSD who are anti-AQP4 antibody positive. A supplemental New Drug Application currently is under review by regulatory authorities in Japan. SOLIRIS received Orphan Drug Designation (ODD) for the treatment of NMOSD in the U.S., EU and Japan.
NMOSD is a rare and severe, autoimmune, inflammatory disorder that attacks the central nervous system (CNS), in which complement activation due to anti-aquaporin-4 (AQP4) antibodies plays a significant role in the disease process. Patients with NMOSD experience unpredictable attacks, also referred to as relapses, which can cause irreversible damage predominantly to the optic nerve and spinal cord and can lead to long-term disability. The most common symptoms of NMOSD are optic neuritis and transverse myelitis. Optic neuritis can cause visual problems including blindness; transverse myelitis can cause mobility problems including paralysis.
The disease primarily affects women, often in the prime of their lives, with an average age of onset of 39 years. The prevalence of NMOSD may be more common and more severe in non-Caucasian populations worldwide.
Complement activation by anti-AQP4 antibodies can cause destruction of vital cells in the CNS, leading to demyelination and to the death of neurons, predominantly in the spinal cord and optic nerve. Approximately three quarters (73%) of all patients with NMOSD have AQP4 antibodies. In patients with anti-AQP4 antibody-positive NMOSD, the body’s own immune system can turn against itself to produce antibodies against AQP4, a protein on certain cells in the optic nerves, brain and spinal cord that are critical for the survival of nerve cells. The binding of these anti-AQP4 antibodies activates the complement cascade, another part of the immune system.
SOLIRIS® (eculizumab) is a first-in-class complement inhibitor that works by inhibiting the C5 protein in the terminal part of the complement cascade, a part of the immune system. The terminal complement cascade, when activated in an uncontrolled manner, plays a role in severe rare and ultra-rare disorders. SOLIRIS, an intravenously administered therapy, is approved in the U.S., EU, Japan and other countries as a treatment for adult patients with PNH and for adults and children with aHUS. SOLIRIS is not indicated for the treatment of patients with Shiga-toxin E. coli-related hemolytic uremic syndrome (STEC-HUS). In the U.S., SOLIRIS is also approved for the treatment of generalized MG (gMG) in adult patients who are anti-AchR antibody-positive and for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adult patients who are anti-AQP4 antibody-positive, in the EU as the first and only treatment of refractory gMG in adults who are anti-AchR antibody-positive and for the treatment of NMOSD in adult patients who are anti-AQP4 antibody-positive with a relapsing course of the disease, and in Japan for the treatment of patients with gMG who are anti-AChR antibody-positive and whose symptoms are difficult to control with high-dose intravenous immunoglobulin (IVIG) therapy or plasmapheresis (PLEX).
INDICATIONS & IMPORTANT SAFETY INFORMATION FOR SOLIRIS® (eculizumab)
What is SOLIRIS?
SOLIRIS is a prescription medicine called a monoclonal antibody. SOLIRIS is used to treat patients with a disease called Paroxysmal Nocturnal Hemoglobinuria (PNH). SOLIRIS is used to treat adults and children with a disease called atypical Hemolytic Uremic Syndrome (aHUS). SOLIRIS is not for use in treating people with Shiga toxin E. coli related hemolytic uremic syndrome (STEC-HUS). SOLIRIS is used to treat adults with a disease called generalized myasthenia gravis (gMG) who are anti-acetylcholine receptor (AchR) antibody positive. SOLIRIS is 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 SOLIRIS is safe and effective in children with PNH, gMG, or NMOSD.
U.S. IMPORTANT SAFETY INFORMATION
SOLIRIS is a medicine that affects the immune system. SOLIRIS can lower the ability of the immune system to fight infections. SOLIRIS 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 two weeks before the first dose of SOLIRIS if one has not already had this vaccine. If one’s doctor decided that urgent treatment with SOLIRIS is needed, meningococcal vaccination should be administered as soon as possible. If one has not been vaccinated and SOLIRIS therapy must be initiated immediately, two 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 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. 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 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.
One’s doctor will provide a Patient Safety Card about the risk of meningococcal infection. Carry the card at all times during treatment and for 3 months after the last SOLIRIS dose.
SOLIRIS is only available through a program called the SOLIRIS REMS.
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.
Do not receive SOLIRIS if one has a meningococcal infection, or has not been vaccinated against meningitis infection unless one’s doctor decides that urgent treatment with SOLIRIS is needed.
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 or 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 during and for at least 12 weeks after stopping treatment 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 the 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. 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).
Please see the accompanying full Prescribing Information and Medication Guide for SOLIRIS, including BOXED WARNING regarding serious and life-threatening meningococcal infections.
