What MabThera is

MabThera contains the active substance “rituximab”. This is a type of protein called a “monoclonal antibody”. It sticks to the surface of a type of white blood cell called “B-Lymphocyte”. When rituximab sticks to the surface of this cell, the cell dies.

What MabThera is used for

MabThera may be used for the treatment of several different conditions in adults. Your doctor may prescribe MabThera for the treatment of:

a) Non-Hodgkin’s Lymphoma

This is a disease of the lymph tissue (part of the immune system) that affects a type of white blood cell called B-Lymphocytes.

MabThera can be given alone or with other medicines called “chemotherapy”.

In patients where the treatment is working, MabThera may be used as a maintenance treatment for 2 years after completing the initial treatment.

b) Chronic lymphocytic leukaemia

Chronic lymphocytic leukaemia (CLL) is the most common form of adult leukaemia. CLL affects a particular lymphocyte, the B cell, which originates from the bone marrow and develops in the lymph nodes. Patients with CLL have too many abnormal lymphocytes, which accumulate mainly in the bone marrow and blood. The proliferation of these abnormal B-lymphocytes is the cause of symptoms you may have. MabThera in combination with chemotherapy destroys these cells which are gradually removed from the body by biological processes.

c) Rheumatoid arthritis

MabThera is used for the treatment of rheumatoid arthritis. Rheumatoid arthritis is a disease of the joints. B lymphocytes are involved in the cause of some of the symptoms you have. MabThera is used to treat rheumatoid arthritis in people who have already tried some other medicines which have either stopped working, have not worked well enough or have caused side effects. MabThera is usually taken together with another medicine called methotrexate.

MabThera slows down the damage to your joints caused by rheumatoid arthritis and improves your ability to do normal daily activities.

The best responses to MabThera are seen in those who have a positive blood test to rheumatoid factor (RF) and/or anti-Cyclic Citrullinated Peptide (anti-CCP). Both tests are commonly positive in rheumatoid arthritis and aid in confirming the diagnosis.

d) Granulomatosis with polyangiitis or microscopic polyangiitis

MabThera is used for the treatment of granulomatosis with polyangiitis (formerly called Wegener’s granulomatosis) or microscopic polyangiitis, taken in combination with corticosteroids. Granulomatosis with polyangiitis and microscopic polyangiitis are two forms of inflammation of the blood vessels which mainly affects the lungs and kidneys, but may affect other organs as well. B lymphocytes are involved in the cause of these conditions.

e) Pemphigus vulgaris

MabThera is used for the treatment of patients with moderate to severe pemphigus vulgaris. Pemphigus vulgaris is an autoimmune condition that causes painful blisters on the skin and lining of the mouth, nose, throat and genitals.

Do not take MabThera if:

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

Do not have MabThera if any of the above apply to you. If you are not sure, talk to your doctor, pharmacist or nurse before you are given MabThera.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before you are given MabThera if:

• you have ever had or might now have a hepatitis infection. This is because in a few cases, MabThera could cause hepatitis B to become active again, which can be fatal in very rare cases. Patients who have ever had hepatitis B infection will be carefully checked by their doctor for signs of this infection
• you have ever had heart problems (such as angina, palpitations or heart failure) or breathing problems.

If any of the above apply to you (or you are not sure), talk to your doctor, pharmacist or nurse before you are given MabThera. Your doctor may need to take special care of you during your treatment with MabThera.

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

• if you think you may have an infection, even a mild one like a cold. The cells that are affected by MabThera help to fight infection and you should wait until the infection has passed before you are given MabThera. Also please tell your doctor if you had a lot of infections in the past or suffer from severe infections.
• if you think you may need any vaccinations in the near future, including vaccinations needed to travel to other countries. Some vaccines should not be given at the same time as MabThera or in the months after you receive MabThera. Your doctor will check if you should have any vaccines before you receive MabThera.

Children and adolescents

Talk to your doctor, pharmacist or nurse before you are given this medicine if you, or your child, are under 18 years of age. This is because there is not much information about the use of MabThera in children and young people.

Other medicines and MabThera

Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines. This is because MabThera can affect the way some other medicines work. Also some other medicines can affect the way MabThera works.

In particular, tell your doctor:

• if you are taking medicines for high blood pressure. You may be asked not to take these other medicines 12 hours before you are given MabThera. This is because some people have a fall in their blood pressure while they are being given MabThera.
• if you have ever taken medicines which affect your immune system – such as chemotherapy or immune-suppressive medicines.

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

Pregnancy and breast-feeding

You must tell your doctor or nurse if you are pregnant, think that you might be pregnant or are planning to become pregnant. This is because MabThera can cross the placenta and may affect your baby.

If you can get pregnant, you and your partner must use an effective method of contraception while using MabThera. You must also do this for 12 months after your last treatment with MabThera.

Do not breast-feed while you are being treated with MabThera. Also do not breast-feed for 12 months after your last treatment with MabThera. This is because MabThera may pass into breast milk.

Driving and using machines

It is not known whether MabThera has an effect on you being able to drive or use any tools or machines.

MabThera contains sodium

This medicine contains 2.3 mmol (or 52.6 mg) sodium per 10 mL vial and 11.5 mmol (or 263.2 mg) per 50 mL vial. Take this into account if you are on a low-sodium diet.

How it is given

MabThera will be given to you by a doctor or nurse who is experienced in the use of this treatment. They will watch you closely while you are being given this medicine. This is in case you get any side effects.

You will always be given MabThera as a drip (intra-venous infusion).

Medicines given before each MabThera administration

Before you are given MabThera, you will be given other medicines (pre-medication) to prevent or reduce possible side effects.

How much and how often you will receive your treatment

a) If you are being treated for non-Hodgkin’s Lymphoma

• If you are having MabThera alone
  MabThera will be given to you once a week for 4 weeks. Repeated treatment courses with MabThera are possible.
• If you are having MabThera with chemotherapy
  MabThera will be given to you on the same day as your chemotherapy. This is usually given every 3 weeks up to 8 times.
• If you respond well to treatment, you may be given MabThera as a maintenance treatment every 2 or 3 months for two years. Your doctor may change this, depending on how you respond to the medicine.

b) If you are being treated for chronic lymphocytic leukaemia

When you are treated with MabThera in combination with chemotherapy, you will receive MabThera infusions on day 0 cycle 1 then day 1 of each cycle for 6 cycles in total. Each cycle has a duration of 28 days. The chemotherapy should be given after the MabThera infusion. Your doctor will decide if you should receive concomitant supportive therapy.

c) If you are being treated for rheumatoid arthritis

Each course of treatment is made up of two separate infusions which are given 2 weeks apart. Repeated courses of treatment with MabThera are possible. Depending on the signs and symptoms of your disease, your doctor will decide when you should receive more MabThera. This may be months from now.

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

Treatment with MabThera uses four separate infusions given at weekly intervals. Corticosteroids will usually be given by injection before the start of MabThera treatment. Corticosteroids given by mouth may be started at any time by your doctor to treat your condition.

If you respond well to treatment, you may be given MabThera as a maintenance treatment. This will be administered as 2 separate infusions which are given 2 weeks apart, followed by 1 infusion every 6 months for at least 2 years. Your doctor may decide to treat you longer with MabThera (up to 5 years), depending on how you respond to the medicine.

e) If you are being treated for pemphigus vulgaris

Each course of treatment is made up of two separate infusions which are given 2 weeks apart. If you respond well to treatment, you may be given MabThera as a maintenance treatment. This will be administered 1 year and 18 months after the initial treatment and then every 6 months as needed or your doctor may change this, depending on how you respond to the medicine.

Infusion reactions

During or within the first 24 hours of the infusion you may develop fever, chills and shivering. Less frequently, some patients may experience pain at the infusion site, blisters, itching, sickness (nausea), tiredness, headache, breathing difficulties, blood pressure raised, wheezing, throat discomfort, tongue or throat swelling, itchy or runny nose, vomiting, flushing or palpitations, heart attack or low number of platelets. If you have heart disease or angina, these reactions might get worse. Tell the person giving you the infusion immediately if you develop any of these symptoms, as the infusion may need to be slowed down or stopped. You may require additional treatment such as an antihistamine or paracetamol. When these symptoms go away, or improve, the infusion can be continued. These reactions are less likely to happen after the second infusion. Your doctor may decide to stop your MabThera treatment if these reactions are serious.

Infections

Tell your doctor immediately if you get signs of an infection including:

• fever, cough, sore throat, burning pain when passing urine or feeling weak or generally unwell
• memory loss, trouble thinking, difficulty walking or sight loss – these may be due to a very rare, serious brain infection, which has been fatal (Progressive Multifocal Leukoencephalopathy or PML).

You might get infections more easily during your treatment with MabThera.

These are often colds, but there have been cases of pneumonia or urinary infections. These are listed below under “Other side effects”.

If you are being treated for rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis or pemphigus vulgaris, you will also find this information in the Patient Alert Card you have been given by your doctor. It is important that you keep this Alert Card and show it to your partner or caregiver.

Skin Reactions

Very rarely, severe blistering skin conditions that can be life-threatening may occur. Redness, often associated with blisters, may appear on the skin or on mucous membranes, such as inside the mouth, the genital areas or the eyelids, and fever may be present. Tell your doctor immediately if you experience any of these symptoms.
