1. What Rystiggo is and what it is used for
What Rystiggo is
Rystiggo contains the active substance rozanolixizumab. Rozanolixizumab is a monoclonal antibody (a type of protein) designed to recognize and bind to FcRn, a protein that prolongs the presence of immunoglobulin G (IgG) antibodies in the body.
Rystiggo is used in combination with standard treatment in adults to treat generalized myasthenia gravis (gMG), an autoimmune disease causing muscle weakness that affects multiple muscle groups in the body. The condition may also cause difficulty breathing, extreme fatigue, and problems with swallowing. Rystiggo is used in adults with gMG who have IgG autoantibodies against either acetylcholine receptors or muscle-specific kinase.
In generalized myasthenia gravis (gMG), these IgG autoantibodies (immune system proteins that attack parts of a person's own body) attack and damage proteins involved in nerve-to-muscle communication, known as acetylcholine receptors or muscle-specific kinase.
By binding to FcRn, Rystiggo reduces the levels of IgG antibodies, including IgG autoantibodies (antibodies directed against the body's own tissues), thereby helping to improve disease symptoms.
2. What you need to know before starting to use Rystiggo
Do not use Rystiggo
- If you are allergic to rozanolixizumab or to any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before starting to use this medicine if you are in any of the following situations:
Myasthenic crisis
Your doctor may not prescribe this medicine if you are using a ventilator, or are likely to require one, due to muscle weakness caused by gMG (myasthenic crisis).
Inflammation of the membranes surrounding the brain and spinal cord (aseptic meningitis)
Aseptic meningitis has been observed in association with this medicine. Seek immediate medical attention if you develop symptoms of aseptic meningitis, such as severe headache, fever, neck stiffness, nausea, vomiting, and/or sensitivity to bright light.
Infections
This medicine may reduce your body's natural resistance to infections. Before starting treatment with this medicine or during treatment, inform your doctor if you have any symptoms of infection (feeling unwell, fever, chills or shivering, cough, sore throat, or cold sores may be signs of an infection).
Hypersensitivity (allergic reactions)
This medicine contains a protein that may cause allergic reactions such as rash, swelling, or itching in some people. You will be monitored for signs of an infusion reaction during treatment and for 15 minutes after.
Vaccinations (vaccines)
Inform your doctor if you have received a vaccine in the past 4 weeks or if you plan to be vaccinated in the near future.
Children and adolescents
Do not administer this medicine to children under 18 years of age, as the use of Rystiggo has not been studied in this age group.
Other medicines and Rystiggo
Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.
Using Rystiggo with other medicines may reduce the effectiveness of those medicines, including therapeutic antibodies (such as rituximab) or subcutaneous or intravenous immunoglobulins. Other medicines, including subcutaneous or intravenous immunoglobulins, or procedures such as plasmapheresis (a process in which the liquid part of the blood, or plasma, is separated from blood drawn from a person), may affect the effect of Rystiggo. Inform your doctor if you are taking or plan to take any other medicine.
Before vaccination, inform your doctor about your treatment with Rystiggo. This medicine may affect the response to vaccines. Vaccination with so-called live or attenuated vaccines is not recommended during treatment with Rystiggo.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.
The effects of this medicine during pregnancy are unknown. You should not use this medicine if you are pregnant or think you might be pregnant unless specifically advised by your doctor.
It is not known whether this medicine passes into breast milk. Your doctor will help you decide whether to breastfeed while using Rystiggo.
Driving and using machines
It is unlikely that Rystiggo will affect your ability to drive or use machines.
Rystiggo contains proline
This medicine contains 29 mg of proline per millilitre of medicine.
Proline may be harmful for patients with hyperprolinemia, a rare genetic disorder in which excess of the amino acid proline accumulates in the body.
If you have hyperprolinemia, inform your doctor and do not use this medicine unless specifically recommended.
Rystiggo contains polysorbate 80
This medicine contains 0.3 mg of polysorbate 80 per millilitre of medicine. Polysorbates may cause allergic reactions. Inform your doctor if you have any known allergies.
3. How to use Rystiggo
Treatment with Rystiggo will be initiated and supervised by a specialist doctor experienced in the treatment of neuromuscular or neuroinflammatory disorders.
How much Rystiggo is administered and for how long
You will receive Rystiggo in cycles of 1 infusion per week for 6 weeks.
Your doctor will calculate the correct dose for you based on your body weight:
- if you weigh at least 100 kg, the recommended dose is 840 mg per infusion (requiring 6 ml per administration)
- if you weigh between 70 kg and less than 100 kg, the recommended dose is 560 mg per infusion (requiring 4 ml per administration)
- if you weigh between 50 kg and less than 70 kg, the recommended dose is 420 mg per infusion (requiring 3 ml per administration)
- if you weigh between 35 kg and less than 50 kg, the recommended dose is 280 mg per infusion (requiring 2 ml per administration)
The frequency of treatment cycles varies for each patient, and your doctor will determine whether it is appropriate for you to receive a new treatment cycle and, if so, when.
Your doctor will advise you on how long you should continue treatment with this medicine.
How Rystiggo is administered
Rystiggo will be administered by a doctor or nurse.
You may also self-inject Rystiggo. You and your doctor or nurse will decide whether, after receiving training from a healthcare professional, you can self-inject this medicine. Another person may also administer the injections after receiving training. Do not self-inject Rystiggo or allow anyone to inject it for you until you have been properly trained.
If you or your caregiver administer Rystiggo injections, you must carefully read and follow the Administration Instructions located at the end of this leaflet (see “Instructions for use”).
This medicine is given as a subcutaneous infusion (under the skin). It is usually injected into the lower abdomen, below the navel. Injections should not be given in areas where the skin is painful, bruised, red, or hardened.
Administration is performed using an infusion pump at a flow rate of up to 20 ml/h.
Alternatively, it may be administered manually (via manual slow injection, i.e., without an infusion pump) at a speed that is comfortable for you.
If you receive more Rystiggo than you should
If you suspect that you have accidentally received a dose of Rystiggo higher than prescribed, consult your doctor for advice.
If you missed or skipped an appointment to receive Rystiggo
If you miss a dose, contact your doctor immediately for advice and to schedule another appointment to receive Rystiggo within the next 4 days. After that, the next dose should be administered according to the original administration schedule until the treatment cycle is complete.
If you stop treatment with Rystiggo
Do not stop using this medicine without first talking to your doctor. Interrupting or stopping treatment with Rystiggo may cause generalized myasthenia gravis symptoms to return.
If you have any further questions about how to use this medicine, ask your doctor, pharmacist, or nurse.
