Axitinib (Inlyta)

Axitinib is a targeted cancer drug and is also known by its brand name Inlyta.

It is a treatment for advanced kidney cancer. You might also have it as part of a clinical trial for other types of cancer.

How it works

Axitinib is a tyrosine kinase inhibitor (TKI) which is a cancer growth blocker. Tyrosine kinase inhibitors work by blocking certain proteins called tyrosine kinases from acting on cells. Tyrosine kinases signal to cancer cells to grow.

Axitinib blocks different types of tyrosine kinase and is called a multi kinase inhibitor. It stops cancer cells forming blood vessels, which the cancer needs in order to grow. This is called anti angiogenesis treatment.

How you have it

Axitinib comes as red tablets. You take them twice a day, about 12 hours apart. You should swallow the tablets whole with a glass of water. You can take them with or without food.

Taking your tablets

You must take tablets according to the instructions your doctor or pharmacist gives you.

You should take the right dose, not more or less.

Talk to your specialist or advice line before you stop taking a cancer drug.

When you have it

You start on a low dose and your doctor may increase the dose after 2 weeks, depending on how you feel.

You usually carry on taking axitinib for as long as it works.

Tests

You might have blood tests before starting treatment and during your treatment. They check your general health and might check your levels of blood cells and other substances in the blood.

Side effects

We haven't listed all the side effects. It is very unlikely that you will have all of these side effects, but you might have some of them at the same time.

How often and how severe the side effects are can vary from person to person. They also depend on what other treatment you are having. For example, your side effects could be worse if you are also having other drugs or radiotherapy.

When to contact your team

Your doctor or nurse will go through the possible side effects. They will monitor you closely during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:

  • you have severe side effects 
  • your side effects aren’t getting any better
  • your side effects are getting worse
Early treatment can help manage side effects better.

Common side effects

These side effects happen in more than 10 in 100 people (10%). You might have one or more of them. They include:

Diarrhoea or constipation

Tell your doctor or nurse if you have diarrhoea or constipation. They can give you medicine to help. 

Low levels of thyroid hormones (hypothyroidism)

The level of your thyroid hormones may drop (hypothyroidism). You may feel tired or cold, gain weight, feel sad or depressed, or your voice may deepen. You will have regular blood tests to check your thyroid hormone levels.

Less common the level of your thyroid hormones might increase (hyperthyroidism).

Loss of appetite and weight loss

You might not feel like eating and may lose weight. It is important to eat as much as you can. Eating several small meals and snacks throughout the day can be easier to manage. You can talk to a dietitian if you are concerned about your appetite or weight loss. 

Headaches

Tell your doctor or nurse if you keep getting headaches. They can give you painkillers to help.

Loss of taste

Taste changes may make you go off certain foods and drinks. You may also find that some foods taste different from usual or that you prefer to eat spicier foods. Your taste gradually goes back to normal a few weeks after your treatment finishes.

High blood pressure (hypertension)

Tell your doctor or nurse if you have headaches, nose bleeds, blurred or double vision or shortness of breath. Your nurse will check your blood pressure regularly.

Increased risk of bleeding

This is due to a drop in the number of platelets in your blood. These blood cells help the blood to clot when we cut ourselves. You may have nosebleeds or bleeding gums after brushing your teeth. Or you may have lots of tiny red spots or bruises on your arms or legs (known as petechia).

Difficulty breathing and coughing

You may have difficulty breathing with wheezing and coughing. Let your doctor or nurse know straight away if this happens. 

Changes to your voice (hoarseness)

Your voice might husky or croaky and sound weaker. 

Feeling or being sick

Feeling or being sick is usually well controlled with anti sickness medicines. Avoiding fatty or fried foods, eating small meals and snacks, drinking plenty of water, and relaxation techniques, can all help.

Tummy (abdominal) pain

Tell your treatment team if you have this. They can check the cause and give you medicine to help. 

Indigestion and heartburn

Contact your doctor or pharmacist if you have indigestion or heartburn. They can prescribe medicines to help.

Sore mouth

You might get a stinging or burning sensation in your mouth.

Less common you might get pain in the back of your mouth and throat. 

Redness and swelling of palms and soles of feet (hand foot syndrome)

The skin on your hands and feet may become sore, red, or may peel. You may also have tingling, numbness, pain and dryness. This is called hand-foot syndrome or palmar plantar syndrome.

Rash, dry skin

Skin problems include a skin rash, dry skin and itching. Talk to your doctor or nurse they might be able to help if this becomes too bad.

Pain in the joints, hands and feet

You might get pain in your joints, hands or feet. Talk to your doctor, nurse or contact the advice line to find out how to ease the pain. 

Protein and blood in your urine

Small amounts of blood and protein in your urine may be found when your nurse tests your urine. This is not harmful.

Tiredness (fatigue)

You might feel very tired and as though you lack energy.

Various things can help you to reduce tiredness and cope with it, for example exercise. Some research has shown that taking gentle exercise can give you more energy. It is important to balance exercise with resting.

Lack of energy and feeling weak

This is usually mild. You can do things to help yourself, including some gentle exercise. It’s important not to push yourself too hard and eat a well balanced diet.

Talk to your doctor or nurse if this effect is stopping you from doing your usual daily activities.

Inflammation of the mouth, throat, nose and lining of the bowel

Your mouth, throat, nose and lining of the bowel might become swollen and irritated. Talk to your doctor, nurse or contact the advice line if this happens.

  • a rise or a drop in the number of red blood cells
  • not enough fluid in your body (dehydration) - make sure you drink plenty of fluids

What else do I need to know?

Other medications, food 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.

This drug contains lactose (milk sugar). If you have an intolerance to lactose, contact your doctor before taking this medicine.

You should not eat grapefruit or drink grapefruit juice when you are taking this drug because it can react with the drug.

Loss of fertility

It is not known whether this treatment affects fertility in people. Talk to your doctor before starting treatment if you think you may want to have a baby in the future.

Contraception and pregnancy

This drug may harm a baby developing in your womb. It is important not to become pregnant or father a child while you are having treatment with this drug and for at least 1 week afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.

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.

Immunisation

Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.

In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and the shingles vaccine (Zostavax).

You can:

  • have other vaccines, but they might not give you as much protection as usual
  • have the flu vaccine (as an injection)
  • be in contact with other people who have had live vaccines as injections

Avoid close contact with people who have recently had live vaccines taken by mouth (oral vaccines) such as oral polio or the typhoid vaccine.

This also includes the rotavirus vaccine given to babies. The virus is in the baby’s poo for up to 2 weeks and could 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 should also avoid close contact with children who have had the flu vaccine nasal spray if your immune system is severely weakened.
