1 What Onkotrone is and what it is used for

Onkotrone contains the active substance mitoxantrone.

Onkotrone belongs to the group of medicines known as antineoplastic or anti-cancer medicines. It also belongs to the subgroup of anti-cancer medicines called anthracyclines. Mitoxantrone prevents cancer cells from growing, as a result of which they eventually die.

Onkotrone is used in the treatment of:

  • advanced stage (metastatic form) of breast cancer;
  • a form of lymph node cancer (non-Hodgkin’s lymphoma);
  • a cancer of the blood in which the bone marrow (the spongy tissue inside the large bones) makes too many white blood cells (acute myeloid leukaemia);
  • a cancer of the white blood cells (chronic myeloid leukaemia) at a stage where it is difficult to control the number of white blood cells (blast crisis). Onkotrone is used in combination with other medicinal products in this indication;
  • pain caused by prostate cancer at an advanced stage of prostate cancer in combination with corticosteroids.

2 What you need to know before you use Onkotrone
Do not use Onkotrone:
  • if you are allergic to mitoxantrone or any of the other ingredients of this medicine (see section 6);
  • if you are allergic to sulphite;
  • if you have a form of asthma (bronchial asthma) with sulphite allergy;
  • if you are breast-feeding (see section “pregnancy and breast-feeding”).

Warning and precautions

Onkotrone should be administered under the supervision of a doctor experienced in the use of cancer medicines that are toxic to your cells (cytotoxic chemotherapy agents).

Onkotrone should be given by slow and freely flowing infusion into the vein.

Onkotrone must not be administered under the skin (subcutaneous), in a muscle (intramuscular), or into the artery (intra-arterial). Severe local tissue damage may occur if Onkotrone leaks in surrounding tissue (extravasation) during administration.

Onkotrone must also not be injected into the space under the brain or spinal cord (intrathecal injection) as this can result in severe injury with permanent impairment.

Talk to your doctor or, pharmacist or nurse before using Onkotrone:

  • if you have liver problems;
  • if you have kidney problems;
  • if you have use Onkotrone before;
  • if your heart is not working well;
  • if you had prior radiotherapy of the chest;
  • if you already use other medicines that affect your heart;
  • if you had previous therapies with anthracyclines or anthracenediones, such as daunorubicin or doxorubicin;
  • if your bone marrow is not working well (is depressed) or if you are in generally poor health;
  • if you have an infection. This infection should be treated before taking Onkotrone;
  • if you plan a vaccination or immunisation during treatment. Vaccinations and immunisations may not work during treatment with Onkotrone and for 3 months after the end of treatment;
  • if you are pregnant or if you and your partner are trying to become pregnant;
  • if you are breast-feeding. You should stop breast-feeding before taking Onkotrone.

Tell your doctor or pharmacist or nurse immediately if you get any of the following signs or symptoms during treatment with Onkotrone:

  • fever, infections, unexplained bleeding or bruising, weakness and easy fatigability;
  • breathlessness (including breathlessness at night), cough, fluid retention (swelling) in the ankles or legs, heart fluttering (irregular heart beat). This may occur either during or months to years after therapy with Onkotrone.

Your doctor may need to adjust your treatment or stop Onkotrone temporarily or permanently.

Blood tests prior and during treatment with Onkotrone

Onkotrone may affect your blood cell counts. Before you start Onkotrone and during treatment, your doctor will do a blood test to count the number of your blood cells. Your doctor will carry out blood tests more often, in which he will in particular monitor the number of white blood cells (neutrophilic leucocytes) in the blood:

  • if you have a low count of a specific type of white blood cells (neutrophils) (less than 1,500 cells/mm³);
  • if you use Onkotrone in high doses (>14 mg/m² per day x 3 days).

Heart function tests prior and during treatment with Onkotrone

Onkotrone may damage your heart and cause a deterioration of your heart function or in more severe cases heart failure. You are more prone to these side effects if you take higher doses of Onkotrone or:

  • if your heart is not working well;
  • if you had prior treatment of the chest with radiation;
  • if you already use other medicines that affect your heart;
  • if you had previous therapies with anthracyclines or anthracenediones, such as daunorubicin or doxorubicin.

Your doctor will do heart function tests before you start Onkotrone and at regular intervals during therapy.

Acute myeloid leukemia (AML) and Myelodysplastic syndrome

A group of anticancer medicines (topoisomerase II inhibitors), including Onkotrone, may cause the following diseases when used alone but especially in combination with other chemotherapy and/or radiotherapy:

  • cancer of white blood cells (acute myeloid leukaemia, AML)
  • a bone marrow disorder that causes abnormally shaped blood cells and leads to leukaemia (myelodysplastic syndrome)

Discolouration of urine and other tissues

Onkotrone may cause a blue-green colouration to the urine for 24 hours after administration. A bluish disolouration of the whites of your eyes, skin and nails may also occur.

Contraception in men and women

Men must not father a child and should use contraceptive measures during and at least 6 months after therapy. Women of childbearing potential should have a negative pregnancy test prior to each dose, and use effective contraception during therapy and for at least 9 months after cessation of therapy.

If this medicine is used during pregnancy or if you become pregnant while taking this medicine, inform your doctor as there may be risks to the foetus.

Fertility

This medicine might increase the risk for transitory or persistent absence of menstruation (amenorrhoea) in women of childbearing age.

Children and adolescents

There is little experience in children and adolescents.

Do not give this medicine to children and adolescents from birth up to age of 18 years as safety and efficacy in children and adolescents have not been established.

Other medicines and Onkotrone

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines. It is particularly important that you mention any of the following medicines. Medicines which may increase the risk of side effects with Onkotrone:

  • Medicines that can damage your heart (e.g. anthracyclines).
  • Medicines that suppress the bone marrow's production of blood cells and platelets (myelosuppressive agents).
  • Medicines that suppress your immune system (immunosuppressive agents).
  • Antivitamin K, in particular if you are taking Onkotrone because you have cancer.
  • Topoisomerase II inhibitors (a groups of anticancer medicines including mitoxantrone) in combination with other chemotherapy and/or radiotherapy. These can cause:
    • cancer of white blood cells (acute myeloid leukaemia, AML);
    • a bone marrow disorder that causes abnormally shaped blood cells and leads to leukaemia (myelodysplastic syndrome).

Ask your doctor or pharmacist if you are not sure whether your medicine is one of the medicines listed above.

These medicines should be used with care or may need to be avoided during your treatment with Onkotrone. If you are taking any of these, your doctor might need to prescribe an alternative medicine for you.

You should also tell your doctor if you are already taking Onkotrone and you are prescribed a new medicine that you have not already taken at the same time as Onkotrone.

Vaccinations and immunisation (protection against the vaccination substances) may not work during treatment with Onkotrone and for three months after the end of treatment.

Pregnancy, breast-feeding and fertility

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 you are given this medicine.

Pregnancy

Onkotrone may cause damage to your unborn child. Therefore you should avoid becoming pregnant.

If you become pregnant during the treatment with Onkotrone, you must tell your doctor immediately and stop treatment with Onkotrone.

You should avoid becoming pregnant. Men must use an effective method of contraception during the treatment and for at least 6 months after discontinuing the treatment.

Women of child-bearing potential should have a negative pregnancy test prior to each dose and must practise effective contraception for at least 9 months after stopping the treatment with Onkotrone.

Breast-feeding

Onkotrone is secreted into breast milk and may cause serious adverse reactions in your baby. You must not breast-feed while using mitoxantrone and for up to one month after the last administration.

Fertility

Onkotrone might increase the risk for transient or persistent absence of menstruation (amenorrhoea) in women of childbearing age. Therefore you should talk to your doctor if you are planning to become pregnant in the future; your eggs may need to be frozen. In men, no data are available.

However, in male animals, damage to the testes and decreased sperm counts were observed.

Driving and using machines

Onkotrone has a minor effect on your ability to drive and use machines. This is caused by possible side effects, such as confusion or feeling tired (see section 4).

If you suffer from these side effects, do not drive any vehicles and/or use any machines.

3 How to use Onkotrone
Posology and method of administration

Onkotrone will be given to you under supervision of a doctor experienced in the use of cytotoxic chemotherapy agents. It must always be administered as an intravenous infusion (in a vein) and must always be diluted before. The infusion liquid can leak out of the vein into the tissue (extravasation). If this happens, the infusion must be stopped and restarted in another vein. You should avoid contact with Onkotrone, especially with the skin, mucous membranes (moist body surfaces, such as the lining of the mouth) and eyes. The individual dose of Onkotrone is calculated by your doctor. The recommended dose is based on your body surface area, which is calculated in square metres (m2) using your height and weight. In addition your blood will be tested regularly during the treatment. The dosage of the medicine will be adjusted in accordance with the results of these tests.

The usual dose is:

Metastatic breast cancer, non-Hodgkin’s lymphoma

If Onkotrone is used alone:

The recommended initial dosage of Onkotrone is 14 mg/m² of body surface area, given as a single intravenous dose, which may be repeated at 21-day intervals, if your blood values have returned to acceptable levels.

A lower initial dosage (12 mg/m² or less) is recommended in patients with low bone marrow reserves e.g. due to prior chemotherapy or poor general condition.

Your doctor will decide precisely which subsequent dosage you need.

For subsequent courses, the prior dose can usually be repeated if white blood cell and platelet counts have returned to normal levels after 21 days.

Combination therapy (if used with other agents)

Onkotrone has been given as part of combination therapy.

In metastatic breast cancer, combinations of Onkotrone with other cytotoxic agents including cyclophosphamide and 5-fluorouracil or methotrexate and mitomycin C have been shown to be effective.

Onkotrone has also been used in various combinations for non-Hodgkin’s lymphoma; however, data are presently limited and specific regimens cannot be recommended.

As a guide, when Onkotrone is used in combination chemotherapy, the initial dose of Onkotrone should be reduced by 2-4 mg/m² below the doses recommended when Onkotrone is used alone.

Acute myeloid leukaemia:

If used alone for recurrence (return of the cancer)

The recommended dosage for remission induction is 12 mg/m² of body surface area, given as a single intravenous dose daily for five consecutive days (total of 60 mg/m² per 5 days).

If used with other agents against cancer:

Your doctor will decide exactly what dosage you need. This dose might be adjusted if:

  • The combination of medicines reduces the production of white and red blood cells as well as platelets in your bone marrow more than Onkotrone used alone;
  • If you have serious liver or kidney problems.

Treatment of blast crisis in (chronic) myeloid leukaemia

Used alone for recurrence

The recommended dosage in relapse is 10 to 12 mg/m² body surface area given as a single intravenous dose daily over 5 consecutive days (total of 50 to 60 mg/m²).

Advanced castrate-resistant prostate cancer

The recommended dosage of Onkotrone is 12 to 14 mg/m² given as a short intravenous infusion every 21 days, in combination with low oral doses of corticosteroids (hormonal medicines that suppress the immune system).

Elderly patients

Elderly patient should receive doses at the low end of the dosing range due to possible reduced liver, kidney or heart function and of possible illness or treatment with other medicines.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
