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