reaction to medicines used to treat leukaemia . Symptoms may include: fever; cough;
trouble breathing; weight gain; rash; decreased urination; dizziness or light-headedness;
rapid weight gain; and swelling of the arms, legs, and neck. TIBSOVO can also cause
QTc Interval Prolongation, regardless of the type of cancer a person has, which can

Full Consumer Medicine Information (CMI)
This leaflet provides important information about using TIBSOVO. 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 TIBSOVO.
Where to find information in this leaflet:
1. Why am I using TIBSOVO?
TIBSOVO contains the active substance ivosidenib.
TIBSOVO is used to treat specific cancers (bile duct cancer and acute myeloid leukaemia)
that contain a particular mutated (abnormal) form of the IDH1 enzyme.
When the IDH1 enzyme is mutated, metabolic changes in the cell can lead to the development
of cancer. TIBSOVO blocks the effects of the mutated enzyme and helps to slow or stop
the cancer from growing.
TIBSOVO can be used to treat adults with bile duct cancer (also known as ‘cholangiocarcinoma’).
It is used to treat patients whose bile duct cancer has spread to other parts of the
body and when therapy with other anti-cancer medicines are no longer working.
TIBSOVO can also be used alone or in combination with another anti-cancer medicine
called azacitidine, to treat adults with acute myeloid leukaemia (AML) who are not
eligible to receive intensive chemotherapy.
TIBSOVO can also be used alone in adults with AML when the disease has come back or
has not improved after previous treatment(s).
TIBSOVO is only used in patients whose cancer is related to a particular mutation
(called R132) in the IDH1 enzyme.
Your doctor will have performed a test confirming the cancer contains the R132-mutated
IDH1 enzyme before deciding that this medicine is the right treatment for you. Speak
to your doctor if you have any questions about this test and the results.
2. What should I know before I use TIBSOVO?
There are some people who shouldn't take TIBSOVO. Please read the list below. If you
think any of these situations apply to you or you have any questions, please see your
doctor.
Warnings
Do not use TIBSOVO if:
you are allergic to ivosidenib or any of the other ingredients of this medicine (listed
in section 3); or
you are already taking medicines such as dabigatran, St.John’s wort, rifampicin or
certain medicines used to treat epilepsy (e.g. carbamazepine, phenobarbital, phenytoin).
Precautions when taking TIBSOVO:
If you have AML, and if your cancer responds to treatment, TIBSOVO can cause a serious
condition known as Differentiation Syndrome, which can be life-threatening if not
treated. Seek urgent medical attention if you develop fever; cough; trouble breathing;
weight gain; rash; swelling of the arms, legs, and neck; build-up of excess fluid
around the heart and lungs; or low blood pressure (see "Serious side effects" in Section
6. Are there any side effects?).
TIBSOVO can cause a serious condition known as QTc interval prolongation, which can
cause life-threatening irregular heartbeats. Seek urgent medical attention if you
feel dizzy, light-headed or faint (see also Section 6. Are there any side effects?)
after taking TIBSOVO.
Guillain-Barré syndrome has happened in patients treated with TIBSOVO. Your doctor
will monitor you for nervous system problems. Tell your doctor if you develop weakness
or tingling feeling in your legs, arms, or upper body, numbness and pain on one side
or both sides of your body, any changes in your ability to see, touch, hear, or taste,
burning or prickling sensation, or difficulty breathing.
If you get any of the above serious side effects, your doctor may give you other medicines
to treat them and they may tell you to stop taking TIBSOVO for a while or stop taking
it altogether.
Check with your doctor if:
you have heart problems including a condition called long QT syndrome or have problems
with abnormal electrolyte levels (such as sodium, potassium, calcium or magnesium);
you are taking certain medicines that can affect the heart (e.g. those used to prevent
arrhythmia called anti-arrhythmics, some antibiotics, some antifungals and those used
to prevent nausea and vomiting - see also Section
3. What if I am taking other medicines?);
you have kidney problems; and/or
you have liver problems.
Other side effects that could happen during treatment are described under Section
? It is important you understand these risks and how to look out for them.
Pregnancy and breastfeeding
It is important to tell your doctor if you are pregnant or intend to become pregnant,
or if you are breastfeeding or intend to breastfeed.
Pregnancy
TIBSOVO is not recommended for use during pregnancy as it may harm the unborn baby.
People of child-bearing age should have a pregnancy test prior to starting treatment
with TIBSOVO and should avoid becoming pregnant during therapy.
If you are pregnant, think you might be pregnant or are planning to have a baby, ask
your doctor for advice before taking this medicine. Contact your doctor or nurse immediately
if you become pregnant whilst taking TIBSOVO.
As TIBSOVO may affect an unborn developing baby, it is important for women not to
become pregnant for at least 1 month after treatment discontinuation.
Contraception
People who might become pregnant, and people who have partners who might become pregnant,
should use effective contraception during treatment with TIBSOVO and for at least
1 month after the last dose.
TIBSOVO may stop hormonal contraceptives from working properly. If you or your partner
use a hormonal contraceptive (e.g. birth control pills, or contraceptive patches or
implants), you should also use a barrier method (e.g. condoms or a diaphragm) to avoid
pregnancy. Talk to your doctor or nurse about the right contraceptive method for you.
Breastfeeding
It is not known if TIBSOVO passes into breast milk. Do not breastfeed your baby during
treatment with TIBSOVO and for at least 1 month after the last dose.
Fertility
It is not known if TIBSOVO affects fertility. If you are concerned about your fertility
whilst taking TIBSOVO talk to your doctor.
Children and adolescents
Do not give this medicine to children and adolescents under 18 years old because there is
no information about its use in this age group.
3. What if I am taking other medicines?
Tell your doctor or pharmacist if you are taking any other medicines, including any
medicines, vitamins or supplements that you buy without a prescription from your pharmacy,
supermarket or health food shop.
This is because they may reduce how well TIBSOVO works or increase the risk of side
effects, or TIBSOVO may affect the way these other medicines work.
In particular, tell your doctor if you are taking any of the following medications:
antibiotics used for bacterial infections (e.g. erythromycin, clarithromycin, benzylpenicillin,
ciprofloxacin, levofloxacin);
warfarin (used to stop blood clots);
medicines used for fungal infections (e.g. itraconazole, ketoconazole, fluconazole, isavuconazole, posaconazole, voriconazole);
medicines that affect your heartbeat known as anti-arrhythmics (e.g diltiazem, verapamil, quinidine);
medicines used to stop nausea and vomiting known as anti-emetics (e.g aprepitant, ondansetron, tropisetron, granisetron);
medicines used after organ transplants known as immunosuppressants (e.g. ciclosporin, everolimus, sirolimus, tacrolimus);
medicines used for HIV (e.g. raltegravir, ritonavir);
alfentanil (used for anaesthesia in surgery);
fentanyl (used for severe pain);
pimozide (used for schizophrenia);
medicines used for cancer (e.g. cyclophosphamide, ifosfamide, paclitaxel);
methadone (used for morphine or heroin addiction, or severe pain);
medicines used for type 2 diabetes (e.g. pioglitazone, repaglinide);
omeprazole (used for stomach ulcers and acid reflux);
furosemide (used for fluid build-up known as oedema);
medicines used for high cholesterol known as statins (e.g. atorvastatin, pravastatin, rosuvastatin); and/or
lamotrigine (used for epilepsy).

or supplements you are taking and if these affect TIBSOVO.
