ITUXREDI 500 mg CONCENTRATE FOR INFUSION SOLUTION

2. What you need to know before you use Ituxredi

Do not use Ituxredi

• if you are allergic to rituximab, to other proteins similar to rituximab, or to any of the other ingredients of this medicine (listed in section 6)
• if you have any severe active infection
• if you have a weakened immune system
• if you have severe heart failure or uncontrolled severe heart disease and you have rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, or pemphigus vulgaris.

Do not use rituximab if you have any of the above. If you are not sure, ask your doctor, pharmacist, or nurse before you are given rituximab.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before using rituximab:

• if you think you have an infectious hepatitis or have had it in the past. This is because in a few cases, patients who had hepatitis B may suffer a relapse that can be fatal in very rare cases. Patients with a history of hepatitis B infection will be closely monitored by their doctor for possible signs of hepatitis B
• if you have had any heart disease (such as angina, palpitations, or heart failure) or respiratory problems.

If any of the above apply to you (or you are not sure), ask your doctor, pharmacist, or nurse before you are given rituximab. Your doctor may need to monitor you during your treatment with rituximab.

Also, ask your doctor if you think you may need to be vaccinated in the near future, including vaccinations needed for travel to other countries. Some vaccinations should not be given at the same time as rituximab or in the months following its administration. Your doctor will check if you need any vaccination before receiving rituximab.

If you have rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, or pemphigus vulgaris, you should also tell your doctor:

• if you think you may have any infection, even if it is mild, such as a cold. The cells that rituximab targets help fight infections, so you should wait until the infection has passed before using rituximab. Also, tell your doctor if you have had many infections in the past or if you have any severe infection.

Children and adolescents

Non-Hodgkin's Lymphoma

Rituximab can be used to treat children and adolescents from 6 months of age and older with non-Hodgkin's lymphoma, specifically CD20-positive diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma (BL) / Burkitt leukemia (mature B-cell acute leukemia) (MBAL) or Burkitt-like lymphoma (BLL).

Talk to your doctor, pharmacist, or nurse before receiving this medicine if you or your child are under 18 years old.

Granulomatosis with Polyangiitis or Microscopic Polyangiitis.

Rituximab can be used to treat children and adolescents 2 years of age and older with granulomatosis with polyangiitis (formerly called Wegener's granulomatosis) or microscopic polyangiitis. There is not much information on the use of rituximab in children and young people with other diseases.

Tell your doctor, pharmacist, or nurse before you are given rituximab if you or your child are under 18 years old.

Other medicines and Ituxredi

Tell your doctor or pharmacist if you are using or have recently used other medicines, including those bought without a prescription or herbal medicines. This is because rituximab may affect the way other medicines work. Also, other medicines may affect the way rituximab works.

In particular, tell your doctor:

• if you are being treated for high blood pressure. You may be told not to take your blood pressure medicines during the 12 hours before you are given rituximab. This is because some people experience a drop in blood pressure during the infusion of rituximab.
• if you have ever taken medicines that affect your immune system – such as chemotherapy or immunosuppressive medicines.

If any of the above apply to you (or you are not sure), ask your doctor, pharmacist, or nurse before you are given rituximab.

Pregnancy and breastfeeding

You should tell your doctor or nurse if you are pregnant, think you may be pregnant, or plan to become pregnant. This is because rituximab can cross the placenta and affect your baby.

If you are of childbearing potential, you and your partner should use an effective method of contraception during treatment with rituximab and for up to 12 months after the last treatment with rituximab. Rituximab passes into breast milk in very small amounts. As the long-term effects on breastfed infants are unknown, breastfeeding is not recommended during treatment with rituximab and for 6 months after treatment.

Driving and using machines

It is not known if Ituxredi affects the ability to drive or use machines.

Ituxredi contains sodium

This medicine contains 52.2 mg of sodium (main component of cooking/table salt) in each 10 ml vial and 261.2 mg of sodium in each 50 ml vial.

This is equivalent to 2.6% (per 10 ml vial) and 13.2% (per 50 ml vial) of the maximum recommended daily intake of sodium for an adult.

3. How to use Ituxredi

How Ituxredi is used

Rituximab will be given to you by a doctor or nurse with experience in the use of this medicine. They will keep you under observation during the administration of rituximab in case you experience any side effects. Rituximab will always be given as an intravenous infusion (drip).

Medicines given before each Ituxredi infusion

Before the administration of rituximab, you will be given other medicines (pre-medication) to prevent or reduce possible side effects.

Dose and frequency of treatment

1. If you are being treated for non-Hodgkin's lymphoma

• If you are being treated with rituximab alone

Rituximab will be given to you once a week for 4 weeks. Treatment cycles with rituximab can be repeated.

• If you are being treated with rituximab with chemotherapy

Rituximab will be given to you on the same day as chemotherapy. It is usually given every 3 weeks up to 8 times.

• If you respond well to treatment, you may continue treatment with rituximab as maintenance every 2 or 3 months for 2 years. Your doctor may change this depending on your response to the medicine.
• If you are under 18 years old, you will be given rituximab with chemotherapy. You will receive rituximab up to 6 times over a period of 3.5 to 5.5 months.

1. If you are being treated for chronic lymphocytic leukemia

When you are being treated with rituximab in combination with chemotherapy, you will receive rituximab infusions on day 0 of cycle 1, then on day 1 of each cycle up to a total of 6 cycles. Each cycle lasts 28 days. Chemotherapy should be given after the rituximab infusion. Your doctor will decide if you should receive supportive therapy.

1. If you are being treated for rheumatoid arthritis

Each treatment cycle consists of two infusions, given 2 weeks apart. Treatment cycles with rituximab can be repeated. Depending on the signs and symptoms of your disease, your doctor may decide if you should receive a higher dose of rituximab at some point, which may occur after several months.

1. If you are being treated for granulomatosis with polyangiitis or microscopic polyangiitis

Treatment with rituximab uses four infusions, given at weekly intervals. Corticosteroids are usually given by injection before starting treatment with rituximab. To treat your disease, your doctor may start giving you oral corticosteroids at any time.

If you are 2 years or older and respond well to treatment, you may be given rituximab as maintenance treatment. This will be given as 2 infusions, 2 weeks apart, followed by 1 infusion every 6 months for at least 2 years. Your doctor may decide to treat you for longer with rituximab (up to 5 years), depending on your response to the medicine.

1. If you are being treated for pemphigus vulgaris

Each treatment cycle consists of two infusions, given 2 weeks apart. If you respond well to treatment, you may be given rituximab as maintenance treatment. This will be given 1 year and 18 months after initial treatment and then every 6 months as needed. Your doctor may change this depending on your response to the medicine.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or nurse.

4. Possible Adverse Effects

Like all medicines, rituximab can cause adverse effects, although not all people suffer from them.

Most of these adverse effects are of mild to moderate intensity, but some of them can be serious and require treatment. In rare cases, some of these reactions have been fatal.

Infusion Reactions

During or up to 24 hours after the first infusion, you may experience fever, chills, and tremors. Other less frequent adverse effects that some patients may experience are: pain at the infusion site, blisters, and itching of the skin, nausea and vomiting, fatigue, headache, difficulty breathing, increased blood pressure, wheezing, throat irritation, swelling of the tongue or throat, itching or nasal congestion, vomiting, flushing or palpitations, heart attack or low platelet count. If you have heart disease or angina, these reactions could worsen. Immediately inform the person administering the infusionif you or your child experience any of these symptoms, as you may need a slower infusion or to interrupt it. You may need additional treatment with antihistamines or paracetamol. When the symptoms disappear or improve, the infusion can continue. After the second infusion, it is less likely that these reactions will appear. Your doctor may decide to discontinue your treatment with rituximab if you have severe infusion reactions.

Infections

Immediately inform your doctor if, after treatment with rituximab, you or your childexperience any symptoms of infection, such as:

• fever, cough, sore throat, burning sensation when urinating, or if you start to feel tired or unwell.
• memory loss, concentration problems, difficulty walking, or vision loss. This may be due to a very rare and serious brain infection, which can be fatal (Progressive Multifocal Leukoencephalopathy or PML).
• fever, headache, neck stiffness, discoordination (ataxia), personality changes, hallucinations, altered consciousness, seizures, or coma – this could be due to a serious brain infection (enteroviral meningoencephalitis), which can be fatal.

You may be more prone to infections after treatment with rituximab. These are usually colds, but cases of pneumonia, urinary tract infections, or severe viral infections have been reported. All of these are included below as "Other Adverse Effects".

If you are being treated for rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, or pemphigus vulgaris, your doctor should have given you a Patient Information Card, where you will also find this information. It is essential that you carry this card and show it to your partner or caregiver.

Skin Reactions

Very rarely, severe blisters can form on the skin that can be fatal. Redness may appear, usually associated with blisters, on the skin or mucous membranes, such as inside the mouth, genital area, or eyelids, and may occur with fever. Inform your doctor immediately if you experience any of these symptoms.
