H What Clofarabine 1 mg/ml concentrate for solution for infusion is and what it is used for

Clofarabine 1 mg/ml concentrate for solution for infusion contains the active substance clofarabine. Clofarabine is one of a family of medicines called anticancer medicines. It works by hindering the growth of abnormal white blood cells, and eventually kills them. It works best against cells which are multiplying quickly – such as cancer cells.

Clofarabine is used to treat children (> 1 year old), teenagers and young adults up to 21 years old with acute lymphoblastic leukaemia (ALL) when previous treatments have not worked or have stopped working. Acute lymphoblastic leukaemia is caused by abnormal growth of some types of white blood cells.

H How to use Clofarabine

1 mg/ml concentrate for solution for infusion

Your treatment with Clofarabine has been prescribed by a qualified doctor experienced in treating leukaemia.

Your doctor will work out the dose that is right for you depending on your height, weight and how well you are. Before Clofarabine is given to you, it will be diluted in a sodium chloride solution (salt and water). Tell your doctor if you are on a controlled sodium diet as it could affect how you will be given your medicine.

Your doctor will give you Clofarabine once every day for 5 days. It will be given to you as an infusion through a long thin tube which goes into a vein (a drip), or into a small medical appliance that is inserted under the skin (port-a-cath) if you (or your child) have one implanted. The infusion will be given over 2 hours. If you (or your child) weigh less than 20 kg, the infusion time may be longer.

Your doctor will monitor your health and may change your dose depending on your response to the treatment. It is important to drink plenty of water to avoid dehydration.

If you use more Clofarabine than you should

If you think you may have been given too much medicine, tell your doctor straight away.

If you forget to use Clofarabine

Your doctor will tell you when you need to be given this medicine. If you think that you have missed a dose, tell your doctor straight away.

The following information is intended for healthcare professionals only:

Special precautions for administration Clofarabine 1 mg/ml concentrate for solution for infusion must be diluted prior to administration. It should be filtered through a sterile 0.2 micrometre syringe filter and then diluted with sodium chloride 9 mg/ml (0.9%) intravenous infusion to produce a total volume according to the examples given in the table below. However, the final dilution volume may vary depending on the patient’s clinical status and physician discretion. (If the use of a 0.2 micrometre syringe filter is not feasible, the concentrate should be pre-filtered with a 5 micrometre filter, diluted and then administered through a 0.22 micrometre in-line filter.)

Suggested dilution schedule based on the recommended dosage of 52 mg/m2/day clofarabine
Body surface area (m2)	Concentrate (ml)*	Total diluted volume
< 1.44	< 74.9	100 ml
1.45 to 2.40	75.4 to 124.8	150 ml
2.41 to 2.50	125.3 to 130.0	200 ml
*Each ml of concentrate contains 1 mg of clofarabine. Each 20 ml vial contains 20 mg of clofarabine. Therefore, for patients with a body surface area < 0.38 m2, the partial contents of a single vial will be required to produce the recommended daily dosage of clofarabine. However, for patients with a body surface area > 0.38 m2, the contents of between 1 to 7 vials will be required to produce the recommended daily dosage of clofarabine.

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