Ultomiris is a medicine that contains the active substance ravulizumab and it belongs to a class of medicines called monoclonal antibodies, that attach to a specific target in the body. Ravulizumab has been designed to attach to the C5 complement protein, which is a part of the body’s defence system called the ‘complement system’.

Ultomiris is used to treat adult and children patients 10 kg and over with a disease called paroxysmal nocturnal haemoglobinuria (PNH), including patients untreated with complement inhibitor and patients who have received eculizumab for at least the past 6 months. In patients with PNH, the complement system is overactive and attacks their red blood cells, which can lead to low blood counts (anaemia), tiredness, difficulty in functioning, pain, abdominal pain, dark urine, shortness of breath, difficulty swallowing, erectile dysfunction and blood clots. By attaching to and blocking the C5 complement protein, this medicine can stop complement proteins from attacking red blood cells and so control symptoms of the disease.

Ultomiris is also used to treat adult and children patients 10 kg and over with a disease affecting the blood system and kidney called atypical haemolytic uremic syndrome (aHUS), including patients untreated with complement inhibitor and patients who have received eculizumab for at least 3 months. In patients with aHUS, their kidneys and blood vessels, including platelets, can be inflamed which can lead to low blood counts (thrombocytopenia and anaemia), reduced or lost kidney function, blood clots, tiredness and difficulty in functioning. Ultomiris can block the body’s inflammatory response, and its ability to attack and destroy its own vulnerable blood vessels and so control symptoms of the disease including injury to the kidneys.

Ultomiris is also used to treat adult patients with a certain type of disease affecting the muscles called generalised Myasthenia Gravis (gMG). In patients with gMG, their muscles can be attacked and damaged by the immune system which can lead to profound muscle weakness, impaired vision and mobility, shortness of breath, extreme fatigue, risk for aspiration, and markedly impaired activities of daily living. Ultomiris can block the body’s inflammatory response, and its ability to attack and destroy its own muscles to improve muscle contraction, thereby reducing symptoms of the disease and impact of the disease on the activities of daily living. Ultomiris is specifically indicated for patients who remain symptomatic despite treatment with other therapies.

Ultomiris is also used to treat adult patients with a disease of the central nervous system that mainly affects the optic (eye) nerves and the spinal cord called Neuromyelitis Optica Spectrum Disorder (NMOSD). In patients with NMOSD, the optic nerves and spinal cord are attacked and damaged by the immune system working incorrectly, which can lead to loss of sight in one or both eyes, weakness or loss of movement in the legs or arms, painful spasms, loss of feeling, problems with bladder and bowel function and marked difficulties with activities of daily living. Ultomiris can block the body’s abnormal immune response, and its ability to attack and destroy its own optic nerves and spinal cord, which reduces the risk of a relapse or attack of NMOSD.

• If you are allergic to ravulizumab or any of the other ingredients of this medicine (listed in section 6).
• If you have not been vaccinated against meningococcal infection.
• If you have meningococcal infection.

Talk to your doctor before using Ultomiris.

Because the medicine blocks the complement system, which is part of the body’s defences against infection, the use of Ultomiris increases your risk of meningococcal infection caused by Neisseria meningitidis. These are severe infections affecting the linings of the brain which can cause inflammation of the brain (encephalitis) and can spread throughout the blood and body (sepsis).

Consult your doctor before you start Ultomiris to be sure that you receive vaccination against Neisseria meningitidis at least 2 weeks before beginning therapy. If you cannot be vaccinated 2 weeks beforehand, your doctor will prescribe antibiotics to reduce the risk of infection until 2 weeks after you have been vaccinated. Ensure that your current meningococcal vaccination is up to date. You should also be aware that vaccination may not always prevent this type of infection. In accordance with national recommendations, your doctor might consider that you need supplementary measures to prevent infection.

Meningococcal infection symptoms

Because of the importance of rapidly identifying and treating meningococcal infection in patients who receive Ultomiris, you will be provided a ‘Patient card’ to carry with you at all times, listing relevant signs and symptoms of meningococcal infection/sepsis/encephalitis.

If you experience any of the following symptoms, you should immediately inform your doctor:

• headache with nausea or vomiting
• headache and fever
• headache with a stiff neck or stiff back
• fever
• fever and rash
• confusion
• muscle aches with flu-like symptoms
• eyes sensitive to light

Treatment for meningococcal infection while travelling

If you are travelling in a region where you are unable to contact your doctor or will be temporarily unable to receive medical treatment, your doctor may prescribe an antibiotic against Neisseria meningitidis to bring with you. If you experience any of the symptoms described above, you should take the course of antibiotics as prescribed. You should bear in mind that you should still see a doctor as soon as possible, even if you feel better after having taken the antibiotics.

Before starting Ultomiris, inform your doctor if you have any infections.

When Ultomiris is given, you may experience reactions to the infusion (drip) (infusion reaction) such as headache, lower back pain, and infusion-related pain. Some patients may experience allergic or hypersensitivity reactions (including anaphylaxis, a serious allergic reaction which causes difficulty breathing or dizziness).

Patients less than 18 years of age must be vaccinated against Haemophilus influenzae and pneumococcal infections.

There are no special precautions needed for the treatment of patients aged from 65 years and over, although experience with Ultomiris in elderly patients with PNH, aHUS, or NMOSD in clinical studies is limited.

Tell your doctor or pharmacist if you are using or have recently used or might use any other medicines.

Women of childbearing potential

The effects of the medicine on an unborn child are not known. Therefore, effective contraception during treatment and up to 8 months after treatment should be used in women who are able to get pregnant.

Pregnancy/ Breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Ultomiris is not recommended during pregnancy and in women of childbearing potential not using contraception.

This medicine has no or negligible influence on the ability to drive and use machines.

Once diluted with sodium chloride 9 mg/mL (0.9%) solution for injection, this medicine contains 0.18 g sodium (main component of cooking/table salt) in 72 mL at the maximal dose. This is equivalent to 9.1% of the recommended maximum daily dietary intake of sodium for an adult.

You should take this into consideration if you are on a controlled sodium diet.

Your dose of Ultomiris will be calculated by your doctor, based on your body weight, as shown in Table 1. Your first dose is called the loading dose. Two weeks after receiving your loading dose, you will be given a maintenance dose of Ultomiris, and this will then be repeated once every 8 weeks for patient above 20 kg and every 4 weeks for patient less than 20 kg.

If you were previously receiving another medicine for PNH, aHUS, gMG, or NMOSD called eculizumab, the loading dose should be given 2 weeks after the last eculizumab infusion.
