1. What Proleukin is and what it is used for

Proleukin is the brand name of aldesleukin. It is a synthetic protein, very similar to a protein produced by the body called interleukin-2 (IL-2). This protein is part of the immune system. IL-2 activates certain white blood cells in the body called lymphocytes, which fight against diseases and infections. IL-2 stimulates the production of lymphocytes in the body, and enhances the body’s defences.

Proleukin is used to treat kidney cancer which has spread to other organs (also called metastatic renal cell carcinoma).

2. What you need to know before you are given Proleukin

Follow carefully all instructions given to you by your doctor.

Your doctor may carry out tests before you are treated with Proleukin. He/she may perform a blood test to check the level of sugar in your blood and check your kidney and liver function. He/she may also test your heart, respiratory and mental performance. He/she will check your response to the treatment at regular intervals and take any necessary action.

You should not be given Proleukin
  • If you are allergic (hypersensitive) to aldesleukin or any of the other ingredients of this medicine (listed in section 6).
  • If you are confined to bed for more than half the day.
  • If it is less than 24 months since your kidney cancer was diagnosed and you have cancer symptoms, even if the cancer has spread to other organs.
  • If you have a history of heart disease.
  • If you have an infection for which you are taking antibiotics.
  • If you have a shortage of oxygen in your blood.
  • If you have serious problems with your liver, kidneys or any other organs.
  • If you suffer from seizures (convulsions or fits), or from brain cancer that has not been successfully treated.
  • If you have had an organ transplant.
  • If you currently use medicines called corticosteroids to treat inflammatory reactions or if you may require these during Proleukin therapy.
  • If you have had rheumatoid arthritis, Crohn’s disease or any other disease caused by your own immune system.

If any of the above applies to you, talk to your doctor. You should not be given Proleukin.

Also, Proleukin should not be given to you if blood tests show that:

  • You have a low level of white blood cells, platelets or red blood cells.
  • You have creatinine or bilirubin levels outside the normal range.
Take special care with Proleukin
  • If you have chest pain or irregular heart beat. In some patients an electrocardiogram (ECG) will be carried out at regular intervals.
  • If you become short of breath or you start breathing faster during treatment.
  • If you feel extremely tired or sleepy, because this may be a signal that you are losing consciousness.

If you get any of the symptoms listed above, tell your doctor immediately.

You should also take special care:

  • If you have a fever, shivers, chills, nausea and/or diarrhoea.
  • If you feel dizzy and notice a fast heart beat. This may be a sign that you have low blood pressure, often seen within 2 to 12 hours after starting Proleukin administration.
  • If you have a bacterial infection, since Proleukin treatment puts you at a higher risk of infection.
  • If you notice mood changes. These in general return to normal after stopping therapy.
  • If you have diabetes. Your blood sugar levels may increase or decrease more than usual.
  • If you have a very itchy red rash or if your skin gets extremely dry during the treatment with Proleukin.

If any of the symptoms listed above gets severe, tell your doctor.

Other medicines and Proleukin

Some medicines can decrease the effect of Proleukin, or increase side effects.

Tell your doctor or pharmacist if you are using any of the following medicines (or have recently used them).

  • Chemotherapy medicines, called tamoxifen, interferon-alpha, cisplatin, vinblastine and/or dacarbazine, used to treat cancer.
  • Medicines called glucocorticoids (a type of steroid), used to treat inflammatory reactions.
  • Medicines called beta-blockers, used to treat high blood pressure.
  • Medicines that affect the heart, central nervous system, liver, kidneys or bone marrow. Consult your doctor if you are not sure what these are.
  • Contrast fluids used in Computerised Tomography (CT) scanning.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Children and adolescents (below 18 years)

Proleukin is not recommended for children and adolescents younger than 18 years.

Older people (65 years and over)

Older patients may be more susceptible to the side effects of Proleukin. Medical staff should take extra care when treating older people.

Pregnancy and breast-feeding
  • Tell your doctor before starting treatment if you are pregnant, if you suspect that you are pregnant, or if you intend to become pregnant. Your doctor will discuss with you the risks and benefits of taking Proleukin during pregnancy.
  • Both male and female patients should use effective contraception while being treated with Proleukin in order to prevent pregnancy. This is done with most other medicines used to treat cancer.
  • Stop breast-feeding during treatment with Proleukin as there is a possibility that serious side effects could affect the baby.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Do not drive or use any tools or machines because Proleukin has side effects which may influence your ability to carry out these activities.

Proleukin contains sodium

Proleukin contains less than 23 mg sodium per 1 ml, and can therefore be considered as ‘sodium-free’.

3. How Proleukin is used

Proleukin can be given to you:

  • either as a drip into a vein (intravenous infusion). This should be carried out in the hospital, under supervision of a doctor or nurse experienced in the use of medicines to treat cancer,
  • or by injection directly under the skin (subcutaneous injection). This can be administered in a hospital, in an outpatient’s department or at home, under supervision of a doctor or nurse.

Before and during your Proleukin therapy, your doctor may perform regular blood tests and chest X-rays, to check your organs and your blood cell counts.

Follow all instructions given to you by your doctor or nurse carefully.

If you have been given more Proleukin than you should

If you have or think you have been given too much Proleukin, contact your doctor or nurse immediately. You might get some of the side effects described in section 4.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. The side effects of this medicine usually disappear within two days after stopping the treatment.

Your doctor may consider it necessary to treat the side effects of Proleukin with other medicines.
