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

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

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.

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).

Side effects

they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.

it may be difficult for your doctor to tell whether the side effects are due to KANJINTI
