What is Rixathon

Rixathon contains the active ingredient “rituximab”. This is a type of protein called “monoclonal antibody”. It binds to the surface of a type of white blood cell called “B lymphocytes”. When rituximab binds to the surface of these cells, it causes their death.

What is Rixathon used for

Rixathon may be used in adults and children for the treatment of several different diseases. Your doctor may prescribe Rixathon for the treatment of:

a)Non-Hodgkin Lymphoma

This is a disease of the lymphatic system (part of the immune system) that affects a type of white blood cell, called B lymphocytes.

Rixathon may be administered in adults alone or with other medications called “chemotherapy”. In adult patients in whom the initial treatment has been effective, Rixathon may be used as maintenance therapy for 2 years after completing the initial treatment.

In children and adolescents, rituximab is administered in combination with “chemotherapy”.

b)Chronic Lymphocytic Leukemia (CLL)

CLL is the most common form of leukemia in adults. B lymphocytes, which are produced in the bone marrow and develop in lymph nodes, are involved. Patients with CLL have too many abnormal lymphocytes that accumulate mainly in the bone marrow and blood. The proliferation of these abnormal lymphocytes may be the cause of some of the symptoms you may experience. Rixathon in combination with chemotherapy destroys these cells, which gradually disappear from the body through biological processes.

c)Rheumatoid Arthritis

Rixathon is used in the treatment of rheumatoid arthritis. Rheumatoid arthritis is a disease of the joints. B lymphocytes are involved, causing some of the symptoms you may experience. Rixathon is used in the treatment of rheumatoid arthritis in people who have already been treated with other medications, which have either stopped working, not worked well enough, or caused adverse effects. Rixathon is usually used in combination with another medication called methotrexate.

Rixathon reduces the damage caused by rheumatoid arthritis to the joints and improves the ability to perform normal daily activities.

The best responses to Rixathon are observed when the blood test for rheumatoid factor (RF) and/or the test for anti-cyclic citrullinated peptide (anti-CCP) is positive. Both tests are usually positive in patients with rheumatoid arthritis and help confirm the diagnosis.

d)Granulomatosis with Polyangiitis (GPA) or Microscopic Polyangiitis (MPA)

Rixathon is used for the treatment of adult and pediatric patients 2 years of age or older with GPA (formerly known as Wegener's granulomatosis) or MPA, administered in combination with corticosteroids.

GPA and MPA are two forms of inflammation of blood vessels that primarily affect lungs and kidneys, but may also affect other organs. B lymphocytes are involved in the cause of these diseases.

e)Pemphigus Vulgaris (PV)

Rixathon is used for the treatment of patients with moderate to severe pemphigus vulgaris.

PV is an autoimmune disease that causes painful blisters on the skin and mucous membranes of the mouth, nose, throat, and genitals.

Do not use Rixathon

•If you are allergic to rituximab, other proteins similar to rituximab, or any of the other components of this medication (listed in section6)

•If you have an active, severe infection

•If you have a weakened immune system

•If you have severe heart failure or uncontrolled severe heart disease and have rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, or pemphigus vulgaris.

Do not use Rixathon if you have any of the above points. If you are unsure, ask your doctor, pharmacist, or nurse before Rixathon is administered to you.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Rixathon:

•If you think you have a hepatitis infection or have had it in the past. This is because in a few cases, patients who had hepatitisB may experience a relapse that can be fatal in rare occasions. Patients with a history of hepatitisB infection will be closely monitored by your doctor to detect possible signs of hepatitisB.

•If you have had any heart disease (such as angina, palpitations, or heart failure) or respiratory problems.

If you are affected by any of the above points (or are unsure), ask your doctor, pharmacist, or nurse before Rixathon is administered to you. Your doctor may need to monitor you during your treatment with Rixathon.

Also ask your doctor if you think you may need to be vaccinated in the near future, including travel vaccines. Some vaccines should not be administered at the same time as Rixathon or in the months following its administration. Your doctor will check if you need any vaccine before receiving Rixathon.

If you have rheumatoid arthritis, granulomatosis with polyangiitis (GPA), microscopic polyangiitis (PAM), or pemphigus vulgaris (PV), you must also inform your doctor:

•If you think you may have an infection, even if it is mild such as a cold. The cells targeted by Rixathon help fight infections, so you should wait until the infection has passed before using Rixathon. Also inform your doctor if you have had many infections in the past or if you have a severe infection.

Children and adolescents

Non-Hodgkin lymphoma

Rituximab can be used for the treatment of children and adolescents, 6 months of age and older, with non-Hodgkin lymphoma, specifically diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma (BL) / Burkitt leukemia (BLA) or Burkitt-like lymphoma (BLL).

Granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (PAM)

Rituximab can be used for the treatment of children and adolescents, 2 years of age and older, with GPA (formerly known as Wegener's granulomatosis) or PAM. There is little information on the use of rituximab in children and young people with other diseases.

There is little information on the use of rituximab in children and adolescents with other diseases.

Inform your doctor, pharmacist, or nurse before rituximab is administered to you if you or your child is under 18years old

Other medications and Rixathon

Inform your doctor or pharmacist if you are using or have recently used other medications, including those purchased without a prescription or herbal medications. This is because Rixathon may affect how other medications work. Also, other medications may affect how Rixathon works.

In particular, inform your doctor if:

•If you are being treated for hypertension. You may be told not to take your medications for 12hours before Rixathon is administered. This is because some people experience a drop in blood pressure during Rixathon infusion

•If you have ever taken medications that affect your immune system – such as chemotherapy or immunosuppressive medications.

If you are affected by any of the above points (or are unsure), ask your doctor, pharmacist, or nurse before Rixathon is administered to you.

Pregnancy and breastfeeding

You must inform your doctor or nurse if you are pregnant, if you think you may be pregnant, or if you intend to become pregnant. This is because Rixathon may cross the placental barrier and affect your baby.

If you are of childbearing age, you and your partner should use an effective contraceptive method during treatment with Rixathon and for 12months after the last treatment with Rixathon. Rixathon passes into breast milk in very small amounts.As the long-term effects on infants are unknown, it is recommended not to breastfeed during treatment with Rixathon or for 6 months after treatment.

Driving and operating machinery

The effects of rituximab on the ability to drive vehicles or operate machinery are unknown.

Rixathon contains sodium

This medication contains 52.6mg of sodium per 10ml vial and 263.2mg of sodium per 50ml vial. This is equivalent to 2.6% (per 10ml vial) and 13.2% (per 50ml vial) of the maximum recommended daily sodium intake for an adult.

How Rixathon is administered

Rixathon will be administered by a doctor or nurse experienced in the use of this medication. They will keep you under observation during the administration of Rixathon in case you experience any adverse effects.

Rixathon will be administered always by intravenous infusion (drip).

Medications administered before each Rixathon infusion

Before the administration of Rixathon, other medications (premedication) will be administered to prevent or reduce possible adverse effects.

Quantity and frequency of treatment

a)If you are being treated for non-Hodgkin lymphoma

•If you are only being treated with Rixathon

Rixathon will be administered once a week for 4 weeks. Treatment cycles with Rixathon can be repeated.

•If you are being treated with Rixathon and chemotherapy

Rixathon will be administered on the same day as chemotherapy. It is usually administered every 3 weeks for up to 8 times.

•If you respond well to treatment, you may continue treatment with Rixathon as maintenance every 2 or 3 months for up to 2 years. Your doctor may modify it depending on your response to the medication.

• If you are under 18 years old, Rixathon will be administered with chemotherapy. You will receive Rixathon up to 6 times during a period of 3.5 to 5.5 months.

b)If you are being treated for chronic lymphocytic leukemia (CLL)

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

c)If you are being treated for rheumatoid arthritis

Each treatment cycle consists of two infusions, both separated by a 2-week interval. Treatment cycles with Rixathon can be repeated. Depending on the signs and symptoms of your disease, your doctor may decide if you should receive a higher dose of Rixathon at some point, which may occur after several months.

d)If you are being treated for granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (PAM)

The treatment with Rixathon uses four separate infusions, administered at weekly intervals. Corticosteroids are usually administered by injection before starting treatment with Rixathon. To treat your disease, your doctor may start administering corticosteroids orally at any time.

If you are 18 years or older and respond well to treatment, you may be administered Rixathon as maintenance treatment. This will be administered in the form of 2 separate infusions with a 2-week interval, followed by 1 infusion every 6 months for at least 2 years. Your doctor may decide to treat you for longer with Rixathon (up to 5 years), depending on your response to the medication.

e)If you are being treated for bullous pemphigoid (BP)

Each treatment cycle consists of two infusions, both separated by a 2-week interval. If you respond well to treatment, you may be administered Rixathon as maintenance treatment. This will be administered 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 medication.

If you have any other questions about the use of this medication, ask your doctor, pharmacist, or nurse.

Like all medicines, this medicine can cause side effects, although not everyone will experience them.

The majority of these side effects are of mild to moderate intensity, but some of them can be severe and require treatment. In rare cases, some of these reactions have been fatal.

Infusion Reactions

During or within 24 hours after the infusion, you may experience fever, chills, and shivering. Other less common side effects that some patients may experience are: pain at the infusion site, blisters, and itching on the skin, nausea and vomiting, fatigue, headache, difficulty breathing, increased blood pressure, wheezing, throat discomfort, swelling of the tongue or throat, itching or congestion in the nose, vomiting, flushing or palpitations, heart attack, or low platelet count. If you have any heart disease or angina, these reactions may worsen.Inform the person administering the infusion immediately if you or your child experience any of these symptoms, as you may need a slower infusion or to stop 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 occur. Your doctor may decide to stop your treatment with Rixathon if you have severe infusion reactions.

Infections

Inform your doctor immediately if, after treatment with Rixathon, you or your child experience any symptoms of infection, such as:

•fever, cough, sore throat, burning sensation while urinating, or if you start feeling tired or unwell.

•memory loss, concentration problems, difficulty walking, or loss of vision. This may be due to a rare and severe brain infection (leucoencephalopathy multifocal progressive or LMP).

• fever, headache, stiff neck,discoordination (ataxia), changeofpersonality, hallucinations,altered consciousness, convulsions, or coma– eventhough this could be due toa severe brain infection (enteroviral meningoencephalitis), which can be fatal.

You may be more susceptible to infections after treatment with Rixathon.

Normally, these are colds, but cases of pneumonia, urinary tract infections, or severe viral infectionshave been reported. All of them are included below as “Other side 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 leaflet that also contains this information. It is essential to carry this leaflet and show it to your partner or caregiver.

Skin Reactions

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