1. What Lenalidomide Grindeks is and what it is used for

What Lenalidomide Grindeks is
Lenalidomide Grindeks contains the active substance ‘lenalidomide’. This medicine belongs to a group of medicines that affect the function of the immune system.

What Lenalidomide Grindeks is used for
Lenalidomide Grindeks is used in adults to treat:

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

Multiple myeloma
Multiple myeloma is a type of cancer that affects 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 to bones and kidneys.
Generally, multiple myeloma is incurable. However, it is possible to achieve temporary significant reduction or elimination of signs and symptoms of the disease. This is called “remission”.

Newly diagnosed multiple myeloma – in patients after bone marrow transplantation
Lenalidomide Grindeks is used alone (without other medicines) as maintenance therapy in patients who have responded adequately after bone marrow transplantation.

Newly diagnosed multiple myeloma – in patients not eligible for bone marrow transplantation
Lenalidomide Grindeks is taken together with other medicines, including:

  • a chemotherapy medicine called ‘bortezomib’;
  • an anti-inflammatory medicine called ‘dexamethasone’;
  • a chemotherapy medicine called ‘melphalan’; and
  • an immunosuppressive medicine called ‘prednisone’.
    Treatment starts with Lenalidomide Grindeks in combination with additional medicines, followed by continued treatment with Lenalidomide Grindeks alone.

If you are 75 years of age or older, or if you have moderate to severe kidney function impairment, your doctor will perform careful assessments before starting treatment.

Multiple myeloma – in previously treated patients
Lenalidomide Grindeks is taken together with an anti-inflammatory medicine called ‘dexamethasone’.
Lenalidomide Grindeks may stop the progression of signs and symptoms of multiple myeloma. It has also been shown to delay relapse of multiple myeloma after treatment.

Myelodysplastic syndromes (MDS)
Myelodysplastic syndromes (MDS) are a group of different blood and bone marrow disorders. Abnormal blood cells are present and do not function properly. Patients may experience various subjective and objective symptoms, including low red blood cell count (anaemia), need for blood transfusions, and risk of infection.

Lenalidomide Grindeks, 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 known as “isolated cytogenetic abnormality with deletion 5q”. This means the patient’s body does not produce enough healthy blood cells;
  • the patient has previously received other treatments that were inappropriate or insufficiently effective.

Taking Lenalidomide Grindeks may increase the production of healthy blood cells by the body by reducing the number of abnormal cells.

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

Follicular lymphoma (FL)
Follicular lymphoma (FL) is a slowly growing malignant cancer affecting B-cells. These are a type of white blood cells that help the body fight infections. In patients with FL, excessive numbers of B-cells may accumulate in the blood, bone marrow, lymph nodes, and spleen.
Lenalidomide Grindeks is taken together with another medicine called “rituximab” for the treatment of adult patients with previously treated follicular lymphoma.

How Lenalidomide Grindeks works
Lenalidomide Grindeks works by affecting the body’s immune system and directly attacking cancer cells. Its mechanism of action includes:

  • inhibition of cancer cell growth;
  • inhibition of blood vessel formation in tumours;
  • stimulation of part of the immune system to attack cancer cells.

2. Important information before taking Lenalidomide Grindeks

Before starting treatment with Lenalidomide Grindeks, carefully read the package leaflets of all medicinal products being used in combination with Lenalidomide Grindeks.
When not to take Lenalidomide Grindeks

  • if the patient is pregnant or suspects she may be pregnant, or plans to become pregnant, because Lenalidomide Grindeks may harm the unborn child (see "Pregnancy, breastfeeding and contraception – information for women and men" in section 2).
  • if the patient may become pregnant, unless she is using all required contraceptive measures (see "Pregnancy, breastfeeding and contraception – information for women and men" in section 2). If the patient may become pregnant, the doctor will document at each follow-up visit that necessary precautions have been taken and will confirm this with the patient.
  • if the patient is allergic to lenalidomide or to any of the other ingredients of this medicine (listed in section 6). If the patient suspects an allergy, she should consult her doctor for advice.

If any of the above situations apply, Lenalidomide Grindeks must not be taken. If in doubt, consult a doctor.

Warnings and precautions
Before starting treatment with Lenalidomide Grindeks, discuss with your doctor,
pharmacist or nurse if:

  • the patient has previously had blood clots, as there is an increased risk of developing blood clots in veins and arteries during treatment;
  • the patient has any signs of infection, such as cough or fever;
  • the patient has or has ever had a viral infection, especially: hepatitis B virus, varicella-zoster virus (chickenpox and shingles), or HIV. If in doubt, consult a doctor. Treatment with Lenalidomide Grindeks may cause reactivation of the virus in carriers, leading to recurrence of infection. The doctor should check whether the patient has ever had hepatitis B.
  • the patient has kidney function disorders – the doctor may adjust the dose of Lenalidomide Grindeks;
  • the patient has had a heart attack, has ever had a blood clot, smokes tobacco, has high blood pressure or high cholesterol levels;
  • the patient experienced an allergic reaction after taking thalidomide (another medicine used in the treatment of multiple myeloma), such as rash, itching, swelling, dizziness or difficulty breathing;
  • the patient has previously experienced any combination of the following symptoms: widespread rash, skin redness, high body temperature, flu-like symptoms, elevated liver enzymes, blood abnormalities (eosinophilia), enlarged lymph nodes – these are symptoms of a severe skin reaction known as "drug reaction with eosinophilia and systemic symptoms" (DRESS) or "drug hypersensitivity syndrome" (see also section 4 "Possible side effects"). If any of the above applies, inform the doctor, pharmacist or nurse before starting treatment.

Contact your doctor or nurse immediately if at any time during or after treatment
the patient experiences any of the following symptoms:

  • blurred vision, loss of vision or double vision, difficulty speaking, muscle weakness in arms or legs, change in walking pattern or balance problems, persistent numbness, reduced sensation or loss of sensation, memory loss or disorientation. All these symptoms may indicate a serious and potentially fatal brain disease known as progressive multifocal leukoencephalopathy (PML). If the above symptoms occurred before starting lenalidomide treatment, inform the 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 called pulmonary hypertension (see section 4).

Tests and examinations
Before starting treatment with Lenalidomide Grindeks and during treatment, the patient will undergo regular blood tests, as this medicine may reduce the number of blood cells that help fight infection (white blood cells) and those that help blood clot (platelets). The doctor will order blood tests:

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

Before starting lenalidomide treatment and during treatment, the patient may be evaluated for circulatory and respiratory problems.

Patients with MDS taking Lenalidomide Grindeks
If the patient has myelodysplastic syndromes (MDS), there is an increased risk of developing a serious disease called acute myeloid leukaemia. Furthermore, it is not known how Lenalidomide Grindeks affects the likelihood of developing acute myeloid leukaemia. Therefore, the doctor may perform tests and check for signs that help better predict the risk of acute myeloid leukaemia during treatment with Lenalidomide Grindeks.

Patients with FL taking Lenalidomide Grindeks
The doctor will request 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.

The doctor may perform a test to determine whether the patient has a large amount of tumour tissue in the body, including in the bone marrow. This may lead to a condition in which tumour tissue begins to break down, causing abnormal increases in various substances in the blood and potentially leading to kidney failure (this condition is known as "tumour lysis syndrome").

The doctor may examine the patient to check for skin changes such as red spots or rash.

The doctor may adjust the dose of Lenalidomide Grindeks or discontinue treatment based on blood test results and the patient's overall condition. If the disease has been recently diagnosed, the doctor may also consider the patient's age and other pre-existing conditions when evaluating treatment.

Blood donation
Do not donate blood during treatment and for at least 7 days after treatment ends.

Children and adolescents
Lenalidomide Grindeks is not recommended for use in children and adolescents under 18 years of age.

Elderly patients and patients with kidney function disorders
If the patient is 75 years of age or older, or has moderate to severe kidney function impairment, the doctor will perform thorough assessments before starting treatment.

Lenalidomide Grindeks and other medicines
Inform your doctor or nurse about all medicines currently taken or recently used. This is necessary because Lenalidomide Grindeks may affect the action of other medicines. Likewise, other medicines may affect the action of Lenalidomide Grindeks.

In particular, inform your doctor or nurse if the patient is taking any of the following medicines:

  • certain contraceptives, such as oral contraceptives, as they may become ineffective;
  • certain heart medications – such as digoxin;
  • certain anticoagulants – such as warfarin.

4. Possible adverse reactions

Like all medicines, Lenalidomide Grindeks may cause adverse reactions, although they do not
occur in everyone.
If any of the following serious adverse reactions occur, stop taking Lenalidomide Grindeks and
seek immediate medical advice – immediate treatment may be required:

  • hives, rash, swelling of the eyes, lips or face, difficulty breathing 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 across the entire body and progressing with significant skin peeling (Stevens-Johnson syndrome and/or toxic epidermal necrolysis);
  • widespread rash, high body temperature, increased liver enzyme activity, abnormalities in blood tests (eosinophilia), swollen lymph nodes and involvement of other organs (drug rash with eosinophilia and systemic symptoms, also known as "DRESS" or "drug hypersensitivity syndrome").

  • shortness of breath;
  • bone pain, muscle weakness, confusion or fatigue, which may result from high levels of calcium in the blood.

Lenalidomide Grindeks may reduce the number of white blood cells that fight infection, as well as
blood cells that help blood clot (platelets), which may lead to bleeding disorders such as nosebleeds
and bruising. Lenalidomide Grindeks may also cause blood clots in the veins (thrombosis).
Other adverse reactions
It should be noted that in a small number of patients, other types of cancer may develop, and
treatment with Lenalidomide Grindeks may possibly increase this risk.
