  • 1. What Myocet liposomal is and what is it used for

Myocet liposomal contains a medicine called “doxorubicin”, which damages tumour cells. This type of medicine is called “chemotherapy”. The medicine is contained inside very small droplets of fat called “liposomes”.

Myocet liposomal is used in adult women for the first-line treatment of breast cancer that has spread (“metastatic breast cancer”). It is used with another medicine called “cyclophosphamide”. Please also read the patient information leaflet carefully that comes with that medicine.

2. What you need to know before you are given Myocet liposomal

Do not have Myocet liposomal:

  • if you are allergic to doxorubicin or any of the other ingredients of this medicine (listed in section 6).

Do not have Myocet liposomal if this applies to you. If you are not sure, talk to your doctor or nurse before having Myocet liposomal.

Warning and precautions

Talk to your doctor or nurse before having Myocet liposomal.

Check with your doctor or nurse before having your medicine if:

  • you have ever had heart problems such as a heart attack, heart failure or you have had high blood pressure for a long time
  • you have liver problems.

If any of the above apply to you (or you are not sure), talk to your doctor or nurse before having Myocet liposomal.

Tests

Your doctor will do tests during your treatment to check that the medicine is working properly. They will also look out for any side effects such as blood problems or heart problems.

Radiation therapy

If you have already had radiation therapy, this may react with Myocet liposomal. You may get painful, red or dry skin. This can happen straight away or later on in your treatment.

Other medicines and Myocet liposomal

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines. This is because Myocet liposomal can affect the way some other medicines work. Also some other medicines can affect the way Myocet liposomal works.

In particular tell your doctor or nurse if you are taking any of the following medicines:

  • phenobarbital or phenytoin – for epilepsy
  • warfarin – for thinning the blood
  • streptozotocin – for cancer of the pancreas
  • cyclosporine – for changing your immune system.

If any of the above apply to you (or you are not sure), please talk to your doctor or nurse before having Myocet liposomal.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or nurse for advice before having Myocet liposomal.

  • Myocet liposomal should not be used during pregnancy unless clearly necessary.
  • Women having Myocet liposomal should not breast-feed.
  • Women who could get pregnant should use effective contraception during treatment with Myocet liposomal and for 6 months after treatment.

Driving and using machines

You may feel dizzy after having Myocet liposomal. If you feel dizzy or are not sure how you feel, do not drive or use any tools or machines.

Myocet liposomal contains sodium

Myocet liposomal is available in cartons containing 1 set or 2 sets of 3 vials (not all pack-sizes may be marketed). When the 3 vials have been mixed together, your medicine contains about 108 mg sodium (main component of cooking/table salt). This is equivalent to 5.4 % of the recommended maximum daily dietary intake of sodium for an adult.

  • 3. How Myocet liposomal is given

This medicine is normally given by a doctor or nurse. It is given as a drip (infusion) into a vein.

How much you will be given

Your doctor will work out exactly how much you need. This is based on the size of your body (measured in “square metres” or “m2”).

The recommended dose is between 60 and 75 mg of the medicine for each square meter of your body:

  • this is given once every 3 weeks
  • the medicine “cyclophosphamide” is given on the same day.

The doctor may give you a lower dose if they think you need it.

The number of times you have the drip depends on:

  • the stage of your breast cancer
  • how well your body responds to the medicine.

Treatment usually lasts for about 3 to 6 months.

If you get Myocet liposomal on your skin

Tell your doctor or nurse straight away if any medicine leaks from the drip (infusion) onto your skin. This is because Myocet liposomal can damage your skin. The drip will be stopped straight away. Ice will be put on the affected area for 30 minutes. Then the drip will be started in another vein.

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

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. The following side effects may happen with this medicine.

Tell your doctor or nurse straight away if you notice any of the following side effects. These are signs of an allergic reaction and your drip (infusion) may have to be stopped:

  • feeling breathless or a tight chest or throat
  • headache or back pain

PREPARATION GUIDE

Myocet liposomal 50 mg powder, dispersion and solvent for concentrate for dispersion for infusion Liposomal doxorubicin hydrochloride

It is important you read the entire contents of this guide prior to the preparation of this medicinal product.

  • 1. PRESENTATION

Myocet liposomal is supplied as a three-vial system: (1) doxorubicin HCl, (2) liposomes, and

  • (3) buffer. In addition to these three components, 0.9% (w/v) sodium chloride solution for injection will also be required for the reconstitution of the doxorubicin HCl. Myocet liposomal must be reconstituted prior to administration.

  • 2. RECOMMENDATIONS FOR SAFE HANDLING

The normal procedures for proper handling and disposal of anti-tumour medicinal products should be adopted, namely:

  • Personnel should be trained to reconstitute the medicinal product.
  • Pregnant staff should be excluded from handling the medicinal product.
  • Personnel handling this medicinal product during reconstitution should wear protective clothing including masks, goggles and gloves.
  • All items for administration or cleaning, including gloves, should be placed in a high-risk, waste disposal bag for high-temperature incineration. Liquid waste may be flushed with large amounts of water.
  • Accidental contact with the skin or eyes should be treated immediately with copious amounts of water.
  • 3. PREPARATION FOR THE INTRAVENOUS ADMINISTRATION

Aseptic technique must be strictly observed throughout handling of Myocet liposomal since no preservative is present.

  • 3.1 Preparation of Myocet liposomal

Step 1. Set up

Two alternative heating methods can be used : a Techne DB-3 Dri Block heater or a water bath:

  • Turn on the Techne DB-3 Dri Block heater and set the controller to 75°C-76°C. Verify the temperature set point by checking the thermometer(s) on each heat block insert.
  • If using a water bath, turn on the water bath and allow it to equilibrate at 58°C (55°C-60°C). Verify the temperature set point by checking the thermometer.

(Please note that whilst the control settings on the water bath and heat block are set to different levels the temperature of the vial contents are in the same range (55°C-60°C)).

  • Remove the carton of constituents from the refrigerator.

Step 2. Reconstitute doxorubicin HCl

  • Withdraw 20 ml sodium chloride solution for injection (0.9%), (not provided in the package), and inject into each vial of doxorubicin HCl, intended for preparation.
  • Shake well in the inverted position to ensure doxorubicin is fully dissolved.

Step 3. Heat in water bath or dry heat block

  • Heat the reconstituted doxorubicin HCl vial in the Techne DB-3 Dri Block heater with the thermometer in the block reading (75°C-76°C) for 10 minutes (not to exceed 15 minutes).
  • If using a water bath, heat the doxorubicin HCl vial with the thermometer temperature reading 55°C-60°C for 10 minutes (not to exceed 15 minutes).
  • While heating proceed to step 4.

Step 4. Adjust pH of liposomes

  • Withdraw 1.9 ml of liposomes. Inject into the buffer vial to adjust the pH of liposomes. Pressure build-up may require venting.
  • Shake well.

Step 5. Add pH-adjusted liposomes to doxorubicin

  • Using a syringe, withdraw the entire vial contents of pH-adjusted liposomes from the buffer vial.
  • Remove the reconstituted doxorubicin HCl vial from the water bath or dry heat block. SHAKE VIGOROUSLY. Carefully insert a pressure-venting device equipped with a hydrophobic filter. Then IMMEDIATELY (within 2 minutes) inject the pH-adjusted liposomes into the vial of heated reconstituted doxorubicin HCl. Remove venting device.
  • SHAKE VIGOROUSLY.
  • WAIT FOR A MINIMUM OF 10 MINUTES BEFORE USING, KEEPING THE MEDICINE AT ROOM TEMPERATURE.

The Techne DB-3 Dri Block Heater is fully validated for use in the constitution of Myocet liposomal. Three inserts, each with two 43.7mm openings per insert must be used. To ensure correct temperature control the use of a 35mm immersion thermometer is recommended.

The resulting reconstituted preparation of Myocet liposomal contains 50 mg of doxorubicin HCl/25 ml of concentrate for liposomal dispersion for infusion (2 mg/ml).

After reconstitution the finished product must be further diluted in 0.9% (w/v) sodium chloride solution for injection, or 5% (w/v) glucose solution for injection to a final volume of 40 ml to 120 ml per 50 mg reconstituted Myocet liposomal so that a final concentration of 0.4 mg/ml to 1.2 mg/ml doxorubicin is obtained.

Once constituted, the liposomal dispersion for infusion containing liposome encapsulated doxorubicin should be a red-orange opaque homogeneous dispersion. All parenteral medicinal products should be inspected visually for particulate matter and discoloration prior to administration. Do not use the preparation if foreign particulate matter is present.

It has been demonstrated that once reconstituted Myocet liposomal has a chemical and physical in-use stability at room temperature for up to 8 hours or in a refrigerator (2OC-8OC) for up to 5 days.

From a microbiological point of view, the product should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2OC-8OC, unless reconstitution and dilution has taken place in controlled and validated aseptic conditions.

Myocet liposomal should be administered by intravenous infusion over a period of 1 hour. Warning: Myocet liposomal must not be administered by the intramuscular or subcutaneous route or as a bolus injection.
