1. What Kleder is and what it is used for

What Kleder is
Kleder contains the active substance lenalidomide. This medicine belongs to a group of medicines that affect the function of the immune system.
What Kleder is used for
Kleder is used in adults to treat:

  • multiple myeloma,
  • myelodysplastic syndromes,
  • mantle cell lymphoma,
  • follicular lymphoma.

Multiple myeloma
Multiple myeloma is a type of cancer that attacks a certain type of white blood cells called plasma cells. These cells accumulate in the bone marrow and divide uncontrollably. This may lead to damage of bones and kidneys.
Multiple myeloma is generally incurable, but it is possible to achieve a temporary significant reduction or disappearance of signs and symptoms of the disease. This is called a “response”.
Newly diagnosed multiple myeloma in patients after bone marrow transplant
In this indication, Kleder is used alone as maintenance treatment after achieving an adequate response following transplant.
Newly diagnosed multiple myeloma – in patients who are not eligible for bone marrow transplant
Kleder is taken in combination with other medicines. These may include:

  • a chemotherapy medicine called “bortezomib”;
  • an anti-inflammatory medicine called “dexamethasone”;
  • a chemotherapy medicine called “melphalan”; and
  • an immunosuppressive medicine called “prednisone”.
    The patient starts treatment with additional medicines and then continues with Kleder alone.

If the patient is 75 years of age or older, or has moderate to severe kidney problems, the doctor will perform careful assessments before starting treatment.
Multiple myeloma – in previously treated patients
Kleder is taken in combination with an anti-inflammatory medicine called “dexamethasone”.
Kleder may stop the progression of signs and symptoms of multiple myeloma. It has also been shown to delay the recurrence of multiple myeloma after treatment.
Myelodysplastic syndromes (MDS)
Myelodysplastic syndromes (MDS) are a group of different blood and bone marrow disorders. There are abnormal blood cells that do not function properly. Patients may experience various subjective and objective symptoms, including low number of red blood cells (anaemia), need for blood transfusions, and risk of infection.
Kleder, used as monotherapy, is indicated for the treatment of adult patients with MDS when all of the following conditions are met:

  • the patient requires regular blood transfusions due to low red blood cell count (transfusion-dependent anaemia);
  • the patient has an abnormality in bone marrow cells called “isolated cytogenetic abnormality of deletion 5q”. This means the patient’s body does not produce enough healthy blood cells;
  • the patient has previously been treated with other therapies that were inappropriate or insufficiently effective.

Taking Kleder may lead to an increase in the number of healthy blood cells produced by the body by reducing the number of abnormal cells:

  • this may lead to a reduction in the number of blood transfusions required. It may even become possible to stop blood transfusions altogether.

Mantle cell lymphoma (MCL)
MCL is a cancer of part of the immune system (lymphatic tissue). It attacks a type of white blood cells called B-lymphocytes or B-cells. Mantle cell lymphoma is a disease characterised by uncontrolled growth of B-lymphocytes, leading to their accumulation in lymphatic tissue, bone marrow, or blood.
Kleder, used as monotherapy, is indicated for the treatment of adult patients who have been previously treated with other medicines.
Follicular lymphoma (FL)
Follicular lymphoma (FL) is a slowly growing malignant cancer that attacks B-lymphocytes. These are a type of white blood cells that help the body fight infections. In patients with FL, too many B-lymphocytes may accumulate in the blood, bone marrow, lymph nodes, and spleen.
Kleder is taken together with another medicine called “rituximab” for the treatment of adult patients with previously treated follicular lymphoma.
How Kleder works
Kleder works by affecting the function of the immune system and directly attacking cancer cells. The medicine works in several different ways:

  • by inhibiting the growth of cancer cells,
  • by inhibiting the development of blood vessels in the tumour,
  • by stimulating part of the immune system to attack cancer cells.

2. What you need to know before taking Kleder
Before starting treatment with Kleder, read carefully the leaflets of all other medicines taken in combination with Kleder.
When not to take Kleder:

  • If you are pregnant, suspect you are pregnant, or plan to become pregnant, because Kleder is expected to be harmful to the unborn child (see section 2 “Pregnancy, breastfeeding and contraception – information for women and men”).
  • If you are a woman who could become pregnant, unless you use all required contraceptive measures (see section 2 “Pregnancy, breastfeeding and contraception – information for women and men”). If you are a woman who could become pregnant, your doctor will always document that necessary measures have been taken and will ensure you are aware of them.
  • If you are allergic to lenalidomide or any of the other ingredients of this medicine listed in section 6. If you suspect an allergy, ask your doctor for advice.

Do not take Kleder if any of these apply to you. If in doubt, consult your doctor.
Warnings and precautions
Before starting Kleder, talk to your doctor, pharmacist, or nurse if:

  • you have previously had blood clots – this means an increased risk of blood clots forming in veins and arteries during treatment;
  • you have any signs of infection, such as cough or fever;
  • you currently have or have previously had a viral infection, particularly hepatitis B virus, varicella-zoster virus (chickenpox and shingles), or HIV. If in doubt, consult your doctor. Treatment with Kleder may cause reactivation of the virus in patients who are carriers. This leads to a recurrence of infection. Your doctor will check whether you have had hepatitis B in the past;
  • you have kidney problems – your doctor may adjust the dose of Kleder;
  • you have had a heart attack (heart attack), blood clot at any time, if you smoke, have high blood pressure, or high cholesterol levels;
  • you had allergic reactions while taking thalidomide (another medicine used to treat multiple myeloma), such as rash, itching, swelling, dizziness, or difficulty breathing;
  • you have previously experienced a combination of any of the following symptoms: widespread rash, skin redness, high body temperature, flu-like symptoms, increased liver enzyme activity, blood abnormalities (eosinophilia), swollen lymph nodes – these are symptoms of a severe skin reaction called drug reaction with eosinophilia and systemic symptoms, also known as “DRESS” or “drug hypersensitivity syndrome” (see also section 4 “Possible side effects”).

If any of the above apply to you, consult your doctor, pharmacist, or nurse.
If at any time during or after treatment you experience:

  • vision disturbances, loss of vision or double vision, difficulty speaking, weakness in the arm or leg, change in walking or balance problems, persistent numbness, reduced sensation or loss of sensation, memory loss or disorientation, tell your doctor or nurse immediately. These may be symptoms of a serious and potentially fatal brain disease called progressive multifocal leukoencephalopathy (PML). If you had such symptoms before treatment with lenalidomide, inform your doctor about any changes in these symptoms.
  • shortness of breath, fatigue, dizziness, chest pain, rapid heartbeat, or swelling of the legs or ankles. These may be symptoms of a serious condition known as pulmonary hypertension (see section 4).

Tests and examinations
Regular blood tests will be performed before and during treatment with Kleder. This is because Kleder may cause a decrease in blood cells involved in fighting infections (white blood cells) and blood clotting (platelets).
Your doctor will ask you to have blood tests:

  • before treatment;
  • weekly for the first 8 weeks of treatment;
  • then at least once a month.

Before starting lenalidomide treatment and during treatment, you may be evaluated for cardiovascular and respiratory disorders.
Patients with MDS taking Kleder
If you have myelodysplastic syndromes, there is an increased chance of developing a serious disease called acute myeloid leukaemia. In addition, it is not known how Kleder affects the likelihood of developing acute myeloid leukaemia. Therefore, your doctor may perform tests and check for signs that help better predict the risk of acute myeloid leukaemia during treatment with Kleder.
Patients with MCL taking Kleder
Your doctor will ask you to have blood tests:

  • before treatment;
  • weekly for the first 8 weeks (2 cycles) of treatment;
  • then every 2 weeks during cycles 3 and 4 (more information in section 3 “Treatment cycle”);
  • then at the beginning of each cycle, and
  • at least once a month.

Patients with FL taking Kleder
Your doctor will ask you to have blood tests:

  • before treatment;
  • weekly for the first 3 weeks (1 cycle) of treatment;
  • then every 2 weeks during cycles 2 to 4 (more information in section 3 “Treatment cycle”);
  • then at the beginning of each cycle, and
  • at least once a month.

Your doctor may perform a test to check whether you have a large amount of tumour tissue in your body, including in the bone marrow. This may lead to a situation where tumour tissue begins to die and causes an abnormal increase in the concentration of various substances in the blood, which may lead to kidney failure (a condition called tumour lysis syndrome).
Your doctor may examine you to check for skin changes such as red spots or rash.
Your doctor may change the dose of Kleder or stop treatment based on your blood test results and your general condition. If the disease has been recently diagnosed, your doctor may also assess treatment based on your age and other conditions you already have.
Blood donation
During treatment and for at least 7 days after treatment ends, you must not donate blood.
Children and adolescents
Kleder is not recommended for use in children and adolescents under 18 years of age.
Elderly patients and patients with kidney problems
If you are 75 years of age or older, or have moderate to severe kidney problems, your doctor will perform careful assessments before starting treatment.
Kleder with other medicines
Tell your doctor or nurse about all medicines you are currently taking or have recently taken. This is necessary because Kleder may affect the action of other medicines. Also, some other medicines may affect how Kleder works.
In particular, inform your doctor or nurse if you are taking the following medicines:

  • certain contraceptives, such as oral contraceptives, because they may stop working;
  • certain medicines used for heart problems – such as digoxin;
  • certain medicines used to thin the blood – such as warfarin.

Pregnancy, breastfeeding and contraception – information for women and men
Pregnancy
For women taking Kleder

  • Do not take Kleder if you are pregnant, because it is expected to be harmful to the unborn child.
  • You must not become pregnant while taking Kleder.
  • Therefore, women who could become pregnant must use an effective method of contraception (see “Contraception”).
  • If you become pregnant while taking Kleder, you must stop treatment immediately and inform your doctor.

For men taking Kleder

  • If the female partner of a man being treated with Kleder becomes pregnant, she should inform her doctor immediately. The patient’s partner should seek medical advice.
  • Men must also use an effective method of contraception (see “Contraception”).

Breastfeeding
Do not breastfeed while taking Kleder, because it is not known whether Kleder passes into human milk.
Contraception
For women taking Kleder
Before starting treatment, ask your doctor about the possibility of becoming pregnant, even if you consider it unlikely.
Women who could become pregnant:

  • will undergo pregnancy tests performed under the supervision of a doctor (before each treatment, at least every 4 weeks during treatment, and at least 4 weeks after treatment ends), except in cases where the fallopian tubes have been cut and sealed to prevent the egg from reaching the uterus (tubal sterilisation)
    AND

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

For men taking Kleder
Kleder passes into human semen. If a woman is pregnant or could become pregnant and does not use an effective method of contraception, her partner must use a condom during treatment and for at least 7 days after treatment ends. This applies also to men who have had a vasectomy. During treatment and for at least 7 days after treatment ends, you must not donate semen.
Driving and using machines
Do not drive or operate machinery if you experience dizziness, fatigue, drowsiness, balance disturbances due to vertigo, or blurred vision after taking Kleder.
Kleder contains lactose and sodium.
Kleder contains lactose. If you have been previously diagnosed with intolerance to certain sugars, you should contact your doctor before taking this medicine.
The medicine contains less than 1 mmol (23 mg) of sodium per capsule, meaning the medicine is considered “sodium-free”.

3. How to take Kleder

Kleder must be administered by healthcare professionals experienced in the treatment of
multiple myeloma, MDS, MCL, or FL.

  • When Kleder is used to treat multiple myeloma in patients who are not eligible for bone marrow transplantation or who have previously received other treatment, the medicine is given in combination with other drugs (see section 1 "Why Kleder is used").
  • When Kleder is used to treat multiple myeloma in patients after bone marrow transplantation, or in patients with MDS or MCL, the medicine is used as monotherapy.
  • When Kleder is used to treat follicular lymphoma, it is given together with another medicine called "rituximab".

Kleder should always be used exactly as prescribed by the doctor. If in doubt, consult the
doctor or pharmacist.
If the patient is taking Kleder together with other medicines, they should read the package leaflet
included with those medicines to obtain information about their use and effects.

Treatment cycle
Kleder is taken on specific days within a period of three weeks (21 days).

  • Each 21-day period is called a treatment cycle.
  • Depending on the day of the cycle, the patient will take one or more medicines. However, on some days, the patient will not take any medicines.
  • After completing each 21-day cycle, the patient should start a new 21-day cycle. OR Kleder is taken on specific days within a period of four weeks (28 days).
  • Each 28-day period is called a treatment cycle.
  • Depending on the day of the cycle, the patient will take one or more medicines. However, on some days, the patient will not take any medicines.
  • After completing each 28-day cycle, the patient should start a new 28-day cycle.

What dose of Kleder should be taken
Before starting treatment, the doctor will inform the patient:

  • how much Kleder should be taken;
  • how much of any other medicines should be taken in combination with Kleder, if other medicines are required;
  • on which days of the cycle each medicine should be taken.

How and when to take Kleder

4. Possible adverse reactions

Like all medicines, this medicine can cause adverse reactions, although not everyone will experience them.
If any of the following serious adverse reactions occur, stop taking Kleder immediately and seek medical advice without delay – immediate treatment may be required:

  • urticaria, rash, swelling of the eyes, lips or face, breathing difficulties or itching, which may be symptoms of severe allergic reactions known as angioedema and anaphylactic reaction;
  • severe allergic reaction possibly starting as a rash in one area, spreading over the entire body and associated with significant skin peeling (Stevens-Johnson syndrome and/or toxic epidermal necrolysis);
  • widespread rash, high fever, increased liver enzyme activity, blood abnormalities (eosinophilia), swollen lymph nodes and involvement of other organs (drug rash with eosinophilia and systemic symptoms also known as "DRESS" or "drug hypersensitivity syndrome"). See also section 2.
