Lenalidomide contains the active substance ‘lenalidomide’. This medicine belongs to a group of medicines which affect how your immune system works.

Lenalidomide is used in adults for:

• Multiple myeloma
• Myelodysplastic syndromes
• Mantle cell lymphoma
• Follicular lymphoma

Multiple myeloma is a type of cancer which affects a certain kind of white blood cell, called the plasma cell.

These cells collect in the bone marrow and divide, becoming out of control. This can damage the bones and kidneys.

Multiple myeloma generally cannot be cured. However, the signs and symptoms can be greatly reduced or disappear for a period of time. This is called a ‘response’.

Newly diagnosed multiple myeloma – in patients who have had a bone marrow transplant

Lenalidomide is used on its own as a maintenance therapy after patients have recovered enough following a bone marrow transplant.

Newly diagnosed multiple myeloma – in patients who cannot have a bone marrow transplant

Lenalidomide is taken with other medicines. These may include:

• a chemotherapy medicine called ‘bortezomib’
• an anti-inflammatory medicine called ‘dexamethasone’
• a chemotherapy medicine called ‘melphalan’ and
• an immunosuppressant medicine called ‘prednisone’.

You will take these other medicines at the start of treatment and then continue to take Lenalidomide on its own.

If you are aged 75 years or older or have moderate to severe kidney problems - your doctor will check you carefully before starting treatment.

Multiple myeloma – in patients who have had treatment before

Lenalidomide is taken together with an anti-inflammatory medicine called ‘dexamethasone’.

Lenalidomide can stop the signs and symptoms of multiple myeloma getting worse. It has also been shown to delay multiple myeloma from coming back following treatment.

MDS are a collection of many different blood and bone marrow diseases. The blood cells become abnormal and do not function properly. Patients can experience a variety of signs and symptoms including a low red blood cell count (anaemia), the need for a blood transfusion, and be at risk of infection.

Lenalidomide is used alone to treat adult patients who have been diagnosed with MDS, when all of the following apply:

• you need regular blood transfusions to treat low levels of red blood cells (‘transfusion-dependent anaemia’)
• you have an abnormality of cells in the bone marrow called an ‘isolated deletion 5q cytogenetic abnormality’. This means your body does not make enough healthy blood cells
• other treatments have been used before, are not suitable or do not work well enough.

Lenalidomide can increase the number of healthy red blood cells that the body produces by reducing the number of abnormal cells:

• this can reduce the number of blood transfusions needed. It is possible that no transfusions will be needed.

MCL is a cancer of part of the immune system (the lymph tissue). It affects a type of white blood cell called ‘B-lymphocytes’ or B-cells. MCL is a disease where B-cells grow in an uncontrolled way and build up in the lymph tissue, bone marrow or blood.

Lenalidomide is used alone to treat adult patients who have previously been treated with other medicines.

FL is a slow growing cancer that affects the B-lymphocytes. These are a type of white blood cells that help your body fight infection. When you have FL, too many of these B-lymphocytes may collect in your blood, bone marrow, lymph nodes and spleen.

Lenalidomide is taken together with another medicine called ‘rituximab’ for the treatment of adult patients with previously treated follicular lymphoma.

Lenalidomide works by affecting the body’s immune system and directly attacking the cancer. It works in a number of different ways:

• by stopping the cancer cells developing
• by stopping blood vessels growing in the cancer
• by stimulating part of the immune system to attack the cancer cells.

• if you are pregnant, think you may be pregnant or are planning to become pregnant, as Lenalidomide is expected to be harmful to an unborn child (see section 2, ‘Pregnancy, breast-feeding and contraception – information for women and men’).
• if you are able to become pregnant, unless you follow all the necessary measures to prevent you from becoming pregnant (see section 2, ‘Pregnancy, breast-feeding and contraception – information for women and men’). If you are able to become pregnant, your doctor will record with each prescription that the necessary measures have been taken and provide you with this confirmation.
• if you are allergic to lenalidomide or any of the other ingredients of this medicine listed in section 6. If you think you may be allergic, ask your doctor for advice.

If any of these apply to you, do not take Lenalidomide. Talk to your doctor if you are not sure.

Talk to your doctor, pharmacist or nurse before taking Lenalidomide if:

• you have had blood clots in the past - you have an increased risk of developing blood clots in the veins and arteries during treatment
• you have any signs of an infection, such as a cough or fever
• you have or have ever had previous viral infection, particularly: hepatitis B infection, varicella zoster, HIV. If you are in doubt, talk to your doctor. Treatment with Lenalidomide may cause the virus to become active again, in patients who carry the virus. This results in a recurrence of the infection. Your doctor should check whether you have ever had hepatitis B infection
• you have kidney problems - your doctor may adjust your dose of Lenalidomide
• you have had a heart attack, have ever had a blood clot, or if you smoke, have high blood pressure or high cholesterol levels
• you have had an allergic reaction whilst taking thalidomide (another medicine used to treat multiple myeloma) such as rash, itching, swelling, dizziness or trouble breathing
• you have experienced in the past a combination of any of the following symptoms: widespread rash, red skin, high body temperature, flu-like symptoms, liver enzyme elevations, blood abnormalities (eosinophilia), enlarged lymph nodes – these are signs of a severe skin reaction called Drug Reaction with Eosinophilia and Systemic Symptoms which is also known as DRESS or drug hypersensitivity syndrome. (see also section 4 “Possible side effects”).

If any of the above apply to you, tell your doctor, pharmacist or nurse before starting treatment.

At any time during or after your treatment, tell your doctor or nurse immediately if you:

• experience blurred, loss of or double vision, difficulty speaking, weakness in an arm or a leg, a change in the way you walk or problems with your balance, persistent numbness, decreased sensation or loss of sensation, memory loss or confusion. These may all be symptoms of a serious and potentially fatal brain condition known as progressive multifocal leukoencephalopathy (PML). If you had these symptoms prior to treatment with lenalidomide, tell your doctor about any change in these symptoms.
• experience shortness of breath, tiredness, dizziness, pain in the chest, a faster heartbeat, or swelling in the legs or ankles. These may be symptoms of a serious condition known as pulmonary hypertension (see section 4).

Before and during the treatment with Lenalidomide you will have regular blood tests. This is because Lenalidomide may cause a fall in the blood cells that help fight infection (white blood cells) and help the blood to clot (platelets).

Your doctor will ask you to have a blood test:

• before treatment
• every week for the first 8 weeks of treatment
• then at least every month after that.

You may be evaluated for signs of cardiopulmonary problems before and during the treatment with lenalidomide.

For patients with MDS taking Lenalidomide

If you have MDS, you may be more likely to get a more advanced condition called acute myeloid leukaemia (AML). In addition, it is not known how Lenalidomide affects the chances of you getting AML. Your doctor may therefore do tests to check for signs which may better predict the likelihood of you getting AML during your treatment with Lenalidomide.

For patients with MCL taking Lenalidomide

Your doctor will ask you to have a blood test:

• before treatment
• every week for the first 8 weeks (2 cycles) of treatment
• then every 2 weeks in cycles 3 and 4 (see section 3 ‘Treatment cycle’ for more information)
• after this it will happen at the start of each cycle and
• at least every month.

For patients with FL taking Lenalidomide

Your doctor will ask you to have a blood test:

• before treatment
• every week for the first 3 weeks (1 cycle) of treatment
• then every 2 weeks in cycles 2 to 4 (see Section 3 ‘Treatment cycle’ for more information)
• After this it will happen at the start of each cycle and
• at least every month.

Your doctor may check if you have a high total amount of tumour throughout the body, including your bone marrow. This could lead to a condition where the tumours break down and cause unusual levels of chemicals in the blood which can lead to kidney failure (this condition is called ‘Tumour Lysis Syndrome’).

Your doctor may check you for changes to your skin such as red spots or rashes.

Your doctor may adjust your dose of Lenalidomide or stop your treatment based on the results of your blood tests and on your general condition. If you are newly diagnosed, your doctor may also assess your treatment based on your age and other conditions you already have.

You should not donate blood during treatment and for at least 7 days after the end of treatment.

Lenalidomide is not recommended for use in children and adolescents under 18 years.

If you are aged 75 years or older or have moderate to severe kidney problems - your doctor will check you carefully before starting treatment.

Tell your doctor or nurse if you are taking or have recently taken any other medicines. This is because Lenalidomide can affect the way some other medicines work. Also, some other medicines can affect the way Lenalidomide works.

In particular, tell your doctor or nurse if you are taking any of the following medicines:

• some medicines used to prevent pregnancy such as oral contraceptives, as they may stop working
• some medicines used for heart problems – such as digoxin
• some medicines used to thin the blood – such as warfarin.

Pregnancy

For women taking Lenalidomide

• You must not take Lenalidomide if you are pregnant, as it is expected to be harmful to an unborn baby.
• You must not become pregnant while taking Lenalidomide. Therefore you must use effective methods of contraception if you are a woman of childbearing potential (see ‘Contraception’).
• If you do become pregnant during your treatment with Lenalidomide, you must stop the treatment and inform your doctor immediately.

For men taking Lenalidomide

• If your partner becomes pregnant whilst you are taking Lenalidomide, you should inform your doctor immediately. It is recommended that your partner seeks medical advice.
• You must also use effective methods of contraception (see ‘Contraception’).

Breast-feeding

You must not breast-feed when taking Lenalidomide, as it is not known if Lenalidomide passes into breast milk.

Contraception

For women taking Lenalidomide

Before starting the treatment, ask your doctor if you are able to become pregnant, even if you think this is unlikely.

If you are able to become pregnant

• you will have pregnancy tests under the supervision of your doctor (before every treatment, at least every 4 weeks during treatment, and at least 4 weeks after the treatment has finished) except where it has been confirmed that the fallopian tubes have been severed and sealed, to stop eggs from reaching the uterus (tubal sterilisation)

AND

• you must use effective methods of contraception for at least 4 weeks before starting treatment, during treatment, and until at least 4 weeks after stopping treatment. Your doctor will advise you on appropriate methods of contraception.

For men taking Lenalidomide

Lenalidomide passes into human semen. If your female partner is pregnant or able to become pregnant, and she does not use effective methods of contraception, you must use condoms during treatment and for at least 7 days after the end of treatment, even if you have had a vasectomy. You should not donate semen or sperm during treatment and for at least 7 days after the end of treatment.

Do not drive or operate machines if you feel dizzy, tired, sleepy, have vertigo or blurred vision after taking Lenalidomide.

Lenalidomide contains lactose. If you have been told by your doctor that you have intolerance to some sugars, contact your doctor before taking this medicine.

Lenalidomide is taken on certain days over 3 weeks (21 days).

• Every 21 days is called a ‘treatment cycle’.
• Depending on the day of the cycle, you will take one or more of the medicines. However, on some days you do not take any of the medicines.
• After completing every 21-day cycle, you should start a new ‘cycle’ over the next 21 days.

OR

Lenalidomide is taken on certain days over 4 weeks (28 days).

• Every 28 days is called a ‘treatment cycle’.
• Depending on the day of the cycle, you will take one or more of the medicines. However, on some days you do not take any of the medicines.
• After completing every 28-day cycle, you should start a new ‘cycle’ over the next 28 days.

Before you start treatment, your doctor will tell you:

• how much Lenalidomide you should take
• how much of the other medicines you should take in combination with Lenalidomide, if any
• on what days of your treatment cycle to take each medicine.

• swallow the capsules whole, preferably with water.
• do not break, open or chew the capsules. If powder from a broken Lenalidomide capsule makes contact with the skin, wash the skin immediately and thoroughly with soap and water.
• healthcare professionals, caregivers and family members should wear disposable gloves when handling the blister or capsule. Gloves should then be removed carefully to prevent skin exposure, placed in a sealable plastic polyethylene bag and disposed of in accordance with local requirements. Hands should then be washed thoroughly with soap and water. Women who are pregnant or suspect they may be pregnant should not handle the blister or capsule.
• the capsules can be taken either with or without food.
• you should take Lenalidomide at about the same time on the scheduled days.

To remove the capsule from the blister:

• press only one end of the capsule out to push it through the foil
• do not put pressure on the centre of the capsule, as this can cause it to break.

Lenalidomide is taken in treatment cycles, each cycle lasting 21 or 28 days (see above ‘Treatment cycle’).

You should continue the cycles of treatment until your doctor tells you to stop.

If you take more Lenalidomide than you should

If you take more Lenalidomide than was prescribed, tell your doctor immediately.

If you forget to take Lenalidomide at your regular time and:

• less than 12 hours have passed - take your capsule immediately.
• more than 12 hours have passed - do not take your capsule. Take your next capsule at the usual time the next day.

• Hives, rashes, swelling of eyes, mouth or face, difficulty breathing, or itching, which may be symptoms of serious types of allergic reactions called angioedema and anaphylactic reaction.
• A serious allergic reaction that may begin as a rash in one area but spread with extensive loss of skin over the whole body (Stevens-Johnson syndrome and/or toxic epidermal necrolysis).
• Widespread rash, high body temperature, liver enzyme elevations, blood abnormalities (eosinophilia), enlarged lymph nodes and other body organs involvement (Drug Reaction with Eosinophilia and Systemic Symptoms which is also known as DRESS or drug hypersensitivity syndrome). See also section 2.

• Fever, chills, sore throat, cough, mouth ulcers or any other symptoms of infection including within the bloodstream (sepsis)
• Bleeding or bruising in the absence of injury
• Chest pain or leg pain
• Shortness of breath
• Bone pain, muscle weakness, confusion or tiredness that might be due to high level of calcium in the blood.

Lenalidomide may reduce the number of white blood cells that fight infection and also the blood cells which help the blood to clot (platelets) which may lead to bleeding disorders such as nosebleeds and bruising. Lenalidomide may also cause blood clots in the veins (thrombosis).

It is important to note that a small number of patients may develop additional types of cancer, and it is possible that this risk may be increased with Lenalidomide treatment. Therefore your doctor should carefully evaluate the benefit and risk when you are prescribed Lenalidomide.
