TRAZIMERA™

Active ingredient: Trastuzumab


Consumer Medicine Information (CMI)

This leaflet provides important information about using TRAZIMERA. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using TRAZIMERA.

Where to find information in this leaflet:

1. Why am I using TRAZIMERA?

TRAZIMERA contains the active ingredient trastuzumab.

TRAZIMERA belongs to a group of medicines known as anti-neoplastic (or anti-cancer) agents. There are many different classes of antineoplastic agents. TRAZIMERA belongs to a class called monoclonal antibodies.

Monoclonal antibodies are proteins made in a laboratory. These proteins are designed to recognise and bind to other unique proteins in the body.

TRAZIMERA binds selectively to a protein called human epidermal growth factor receptor 2 (HER2).

HER2 is found in large amounts on the surface of some cancer cells.

When TRAZIMERA binds to HER2 it stops the growth and spread of the cancer cells.

TRAZIMERA is used to treat breast and gastric cancer. It is only used in patients whose tumour has tested positive to HER2.

TRAZIMERA may be used alone or with other medicines that treat breast cancer, such as an aromatase inhibitor (hormone receptor positive breast cancer) or a taxane (e.g. paclitaxel or docetaxel).

For the treatment of gastric cancer TRAZIMERA is used with chemotherapy medicines cisplatin and capecitabine (or 5FU).

Ask your doctor if you have any questions about why TRAZIMERA has been prescribed for you.

2. What should I know before I use TRAZIMERA?

Warnings

Do not use TRAZIMERA if:
  1. You are allergic to any medicine containing trastuzumab, any protein of Chinese hamster origin, or any of the ingredients listed at the end of this leaflet. Some of the symptoms of an allergic reaction may include:
  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other part of the body
  • rash, itching or hives on the skin
  1. You have breast cancer that has not spread (non-metastatic) and
  • you have had an LVEF test result (which measures how well your heart can pump blood) of less than 45% or
  • you have symptoms of heart failure

Symptoms of heart failure may include:

  • shortness of breath or getting tired easily after light physical activity (such as walking)
  • shortness of breath at night, especially when lying flat

  • abnormal or irregular heartbeat

If you are not sure whether you should start receiving this medicine, talk to your doctor.

Check with your doctor if you:

  • have a history of heart disease with:
    • angina (chest pain)
    • cardiac arrhythmias (abnormal beating of the heart)
    • heart failure (where the heart cannot pump blood normally)
    • coronary artery disease (also known as CAD, a condition where plaque builds up inside the arteries)
    • poorly controlled high blood pressure
  • have previously been treated with chemotherapy medicines known as anthracyclines (e.g. doxorubicin); these medicines can damage heart muscle and increase the risk of heart problems with TRAZIMERA

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding
