Find out about ponatinib, how you have it and other important information about taking this cancer drug.
Ponatinib is also called by its brand name Iclusig. It is a treatment for:
- chronic myeloid leukaemia where the leukaemic cells have gene change (mutation) called T315I
- acute lymphoblastic leukaemia that has an abnormal chromosome called the Philadelphia chromosome, or has the T315I mutation
You may also have it as part of clinical trials for other cancers.
How it works
Ponatinib is a type of drug called a protein tyrosine kinase inhibitor (TKI). Tyrosine kinases are proteins that act as chemical messengers to stimulate cancer cells to grow. Ponatinib blocks and interferes with how cells make a number of protein kinases. It is called a multi kinase inhibitor.
How you have it
Ponatinib comes as tablets. You swallow the tablets whole with a glass of water once a day. You can take them with or without food.
Taking your tablets or capsules
Whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, not more or less.
Never stop taking a cancer drug without talking to your specialist first.
When you have it
You usually carry on taking ponatinib for as long as it works, unless the side effects get too bad.
Tests during treatment
You have blood tests before starting treatment and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
Other medicines, foods and drink
Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.
Some medicines, foods and herbal supplements that contain CYP enzymes can interfere with how ponatinib works. Speak to your doctor about this.
Grapefruit and grapefruit juice
You should not eat grapefruit or drink grapefruit juice when you are taking this drug because it can react with the drug.
Pregnancy and contraception
This treatment might harm a baby developing in the womb. It is important not to become pregnant or father a child while you are having treatment and for a few months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
Don’t breastfeed during this treatment because the drug may come through in your breast milk.
You may not be able to become pregnant or father a child after treatment with this drug. Talk to your doctor before starting treatment if you think you may want to have a baby in the future. Men may be able to store sperm before starting treatment. Women may be able to store eggs or ovarian tissue but this is rare.
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment if you need treatment for anything else, including teeth problems.
Don’t have immunisations with live vaccines while you’re having treatment and for at least 6 months afterwards.
In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and shingles vaccine (Zostavax).
- have other vaccines, but they might not give you as much protection as usual
- have the flu vaccine
- be in contact with other people who've had live vaccines as injections
Avoid contact with people who’ve had live vaccines taken by mouth (oral vaccines). This includes the rotavirus vaccine given to babies. The virus is in the baby’s urine for up to 2 weeks and can make you ill. So, avoid changing their nappies for 2 weeks after their vaccination if possible. Or wear disposable gloves and wash your hands well afterwards.
You also need to avoid anyone who has had oral polio or typhoid vaccination recently.
Possible long term effects
Ponatinib is a fairly new drug in cancer treatment. This means that there is limited information available at the moment about possible longer term effects that it may cause. Tell your doctor if you notice anything that is not normal for you.
