What is in this leaflet

This leaflet answers some common questions about KANJINTI. It does not contain all the available information.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you being given KANJINTI against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What KANJINTI is given for

KANJINTI contains an active ingredient called trastuzumab.

KANJINTI is a biosimilar medicine. A biosimilar medicine is a highly similar version of an original brand of a biological medicine, marketed by a different manufacturer once the patent on the original brand expires. Biosimilar brands of biological medicines are thoroughly tested to show that they are just as safe and effective as the original brand.

KANJINTI belongs to a group of medicines known as anti-neoplastic (or anti-cancer) agents. There are many different classes of anti-neoplastic agents. KANJINTI 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.

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

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

KANJINTI 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, KANJINTI is used with chemotherapy medicines cisplatin and capecitabine (or 5FU).

For further information about the other medicines you are receiving with KANJINTI, please ask your doctor, nurse or pharmacist for the Consumer Medicine Information (CMI) leaflet.

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

This medicine is available only with a doctor's prescription.

Before you are given KANJINTI

When you must not be given it

Do not use KANJINTI if:

you have had an allergic reaction to;

KANJINTI,

any ingredient listed at the end of this leaflet or

any protein of chinese hamster origin.

Some symptoms of an allergic reaction may include shortness of breath; wheezing or difficulty breathing; rash, itching or hives on the skin or swelling of the face, lips, tongue or other parts of the body.

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 tire easily after light physical activity (such as walking)

shortness of breath at night, especially when lying flat

swelling of the hands or feet due to fluid build up

abnormal or irregular heartbeat

If you are not sure if you should start receiving KANJINTI, talk to your doctor.

Before you are given it

Tell 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

you 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 KANJINTI

Your doctor will monitor your heart function closely before and during your treatment with KANJINTI. Your heart function may also be monitored for years after ceasing KANJINTI treatment.

if you have any breathing or lung problems

you are allergic to any other medicines or any other substances such as foods, preservatives or dyes

Allergic or anaphylactic reactions can occur with KANJINTI treatment (known as infusion or administration related reactions). Your doctor or nurse will monitor you for side effects during treatment. See "side effects" for symptoms to look out for.

you are pregnant or intend to become pregnant

KANJINTI may be harmful to an unborn baby. If there is a need for KANJINTI treatment when you are pregnant, your doctor will discuss the risks and benefits to you and the unborn baby.

You should use effective contraception to avoid becoming pregnant while you are being treated with KANJINTI, and for 7 months after stopping treatment.

you are breast-feeding or plan to breast-feed

It is not known if KANJINTI passes into breast milk. It is recommended that you discontinue breast-feeding while you are being treated with KANJINTI and not restart breast-feeding until 7 months after completing KANJINTI treatment

If you have not told your doctor about any of the above, tell them before you are given KANJINTI.

Use in children

The safety and effectiveness of KANJINTI in children under 18 years of age have not been established.

Taking other medicines

Tell your doctor if you are taking any other medicines including any that you have bought without a prescription from a pharmacy, supermarket or health food shop.

KANJINTI treatment with gemcitabine, vinorelbine, a taxane or radiation therapy can increase the chance of lung problems (interstitial lung disease).

Your doctor and pharmacist have more information on medicines to be careful with or avoid while receiving KANJINTI.

Tell your doctor or pharmacist that you have had KANJINTI if you start any new medication in the seven months after stopping treatment.

It may take up to seven months for KANJINTI to be removed from your body

KANJINTI is given by "drip" into a vein (intravenous (IV) infusion).

The first KANJINTI infusion is given over 90 minutes. If the first infusion is well tolerated, your drip time may be shortened to 30 minutes.

For the treatment of gastric cancer, KANJINTI is given every three weeks in combination with other medicines used to treat gastric cancer.

Your doctor will decide how long you should receive KANJINTI, this will depend on your response to the medicine and the state of your disease.

Side effects

KANJINTI helps most people with HER2 positive breast and gastric cancer, but it may have some unwanted side effects in some people.

Ask your doctor or pharmacist to answer any questions you may have.

Because KANJINTI may be used with other medicines that treat breast and gastric cancer, it may be difficult for your doctor to tell whether the side effects are due to KANJINTI or due to the other medicines.
