1. Contents of the pack and further information

1. What is Savene and what is it used for

Savene contains the active substance dexrazoxane, which acts as an antidote to certain anti-cancer medicines called anthracyclines.

Most anti-cancer medicines are given by injection into a vein. Sometimes an accident can happen and the medicine can leak out of the vein into the surrounding tissue or leak out of the vein into the surrounding tissue. This event is called extravasation. It is a serious complication because it can cause serious damage to the tissue.

Savene is used to treat anthracycline extravasation in adults.

It can reduce the amount of tissue damage caused by anthracycline extravasation.

2. What you need to know before you use Savene

Do not use Savene:

• If you are allergic to dexrazoxane or any of the other ingredients of this medicine (listed in section 6).
• If you are planning to become pregnant and are not using adequate contraceptive measures
• If you are breast-feeding
• If you are being given the yellow fever vaccine.

Warnings and precautions

Talk to your doctor or nurse before you start using Savene:

• Savene should only be given to you if you have had an extravasation when receiving chemotherapy with anthracyclines.
• During treatment with Savene, the area where the extravasation occurred will be regularly examined and you will have regular blood tests to check your blood cells.
• If you have liver problems, your doctor will monitor your liver function during treatment.
• If you have kidney problems, your doctor will monitor any signs of changes in your blood cells.

Children and adolescents

Savene must not be given to children under 18 years of age.

Using Savene with other medicines

Tell your doctor or nurse if you are using, have recently used or might use any other medicines.

In particular, tell your doctor or nurse if you are using or might use any of the following medicines:

• Vaccines: you must not use Savene if you are going to be given the yellow fever vaccine and it is not recommended to use Savene if you are going to be given a vaccine that contains live virus particles.
• A product called DMSO (which is a cream used to treat certain skin conditions)
• Phenytoin (a treatment for fits) Savene may reduce the effectiveness of this medicine.
• Anticoagulants (which thin the blood) (you may need to have more frequent checks).
• Ciclosporin or tacrolimus (both of which reduce the body's immune system and are used to prevent organ rejection after an organ transplant).
• Medicines that reduce the production of red, white or platelet blood cells.

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 for advice before using this medicine.

Savene must not be given if you are pregnant.

You must not breast-feed if you are being treated with Savene.

If you are sexually active, you are advised to use an effective method of contraception to prevent pregnancy during treatment and for 6 months after treatment, both if you are male or female (see section 2 “Do not use Savene”).

Information on the effect of Savene on fertility is limited. If you have any concerns about this, talk to your doctor.

Driving and using machines

Dizziness, fatigue and sudden fainting have been reported in a few patients treated with Savene. The treatment is considered to have a minor influence on the ability to drive and use machines.

Savene contains potassium and sodium

The Savene solvent contains 98 mg of potassium per 500 ml vial which may be harmful to people on a low potassium diet or who have kidney problems. If you are at risk of having high levels of potassium in your blood, your doctor will monitor this.

The Savene solvent also contains 1.61 g of sodium (the main component of cooking/table salt) per 500 ml vial. This is equivalent to 81% of the maximum recommended daily intake of sodium in the diet of an adult.

3. How to use Savene

Savene will be given to you under the control of a doctor with experience in the use of cancer treatments.

Recommended dose

The dose will depend on your height, weight and kidney function. Your doctor will calculate your body surface area in square metres (m2) to determine the dose you should receive. The recommended dose in adults (with normal kidney function) is:

Day 1: 1,000 mg/m2

Day 2: 1,000 mg/m2

Day 3: 500 mg/m2

Your doctor may reduce your dose if you have kidney problems.

Savene will be given to you by infusion into one of your veins. The infusion will last 1-2 hours.

Frequency of administration

You will receive your infusion once a day for 3 consecutive days. The first infusion will be given as soon as possible and within the first 6 hours after anthracycline extravasation. The Savene infusion will be given at the same time each day of treatment.

Savene will not be used again in the next cycle of anthracycline treatment unless another extravasation occurs.

If you receive more Savene than you should

If you receive more Savene than you should, you will be closely monitored, with particular attention to your blood cells, possible gastrointestinal signs, skin reactions and hair loss.

If Savene comes into contact with the skin, the affected area should be rinsed immediately with plenty of water.

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

1. PREPARATION FOR INTRAVENOUS ADMINISTRATION

3.1Reconstitution of Savene powder to prepare a concentrate

3.1.1 Using a syringe with a built-in needle, aseptically withdraw 25 ml from the Savene solvent vial.

3.1.2 Inject the entire contents of the syringe into the vial containing Savene powder.

3.1.3 Remove the syringe and needle and manually mix by repeatedly inverting until the powder is completely dissolved. Do not shake.

Aseptically withdraw the appropriate volume, which contains 20 mg of dexrazoxane per ml, from the appropriate number of vials of concentrate, based on the dose required for the patient expressed in mg. Use a graduated syringe equipped with a needle.

3.2.2 Inject the reconstituted volume back into the opened Savene solvent vial (see point 3.1.5). The solution must not be mixed with any other medicine.
