Nintedanib is a targeted cancer drug. it’s also known as Vargatef.
It is a treatment for a type of non-small cell lung cancer (NSCLC) called adenocarcinoma.
Nintedanib is for people who have already had one type of chemotherapy and whose lung cancer has:
-
spread to surrounding tissues (
locally advanced 
)
-
spread to distant parts of the body (
metastatic cancer
)
- returned after treatment
You have it with a type of chemotherapy called docetaxel.
You may also have nintedanib as part of a clinical trial for other types of cancer.
How does nintedanib work?
Nintedanib is a cancer growth blocker. It blocks particular proteins called protein kinases on the cancer cells. The protein kinases encourage the cancer to grow. Nintedanib blocks a number of these proteins and is called a multi kinase inhibitor. It also stops the cancer cells growing their own blood vessels, which the cells need to be able to grow.
Nintedanib may shrink the cancer or stop it growing for a time.
How do you have nintedanib?
Nintedanib is a capsule that you swallow whole with a glass of water. Do not crush or chew the capsules. You should take nintedanib with food.
Taking your capsules
You must take capsules according to the instructions your doctor or pharmacist gives you.
You should take the right dose, not more or less.
Talk to your healthcare team before you stop taking a cancer drug or if you miss a dose.
How often do you have nintedanib?
You usually take nintedanib twice a day, morning and evening, 12 hours apart.
You take nintedanib with docetaxel as part of a 21 day
. Your doctor will tell you how many cycles you will have.
You have it in the following way:
- You have docetaxel as a drip into your bloodstream over 1 hour.
- You take nintedanib capsules in the morning and evening at least 12 hours apart. You swallow them whole and you should take them with food.
When you have finished your treatment cycles taking docetaxel and nintedanib together, you carry on taking nintedanib on its own every day.
You usually keep taking it for as long as it is working or until the side effects get too bad.
Tests

What else do I need to know?
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.
Do not take nintedanib if you are allergic to peanuts and soy. The capsule contains soya products. People who have a peanut allergy can also have an allergic reaction to soya preparations. This allergic reaction could be life threatening.
Pregnancy and contraception
Nintedanib may harm a baby developing in the womb. It is important not to become pregnant or father a child while you are having treatment with this drug and for at least 3 months afterwards.
Talk to your doctor, nurse, or pharmacist about effective contraception before starting treatment. This treatment may have an effect on how well hormonal contraceptives work. If you’re taking hormonal contraceptives like the pill, injections, or patches you should use additional barrier contraceptives such as condoms.
Let your doctor or nurse know straight away if you or your partner falls pregnant while having treatment.
Loss of fertility
You may not be able to become pregnant or get someone pregnant 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 might be able to store sperm before starting treatment. And women might be able to store eggs or ovarian tissue. But these services are not available in every hospital, so you would need to ask your doctor about this.
Breastfeeding
It is not known whether this drug comes through into breast milk. Doctors usually advise that you don’t breastfeed during this treatment
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment. For example, if you need treatment for anything else, including teeth problems.
Immunisations
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 one of the shingles vaccines called Zostavax.
You can have:
- other vaccines, but they might not give you as much protection as usual
- the flu vaccine (as an injection)
- the coronavirus (COVID-19) vaccine - talk to your doctor or pharmacist about the best time to have it in relation to your cancer treatment
Members of your household who are aged 5 years or over are also able to have the COVID-19 vaccine. This is to help lower your risk of getting COVID-19 while having cancer treatment and until your
recovers from treatment.
Contact with others who have had immunisations - You can 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 the oral typhoid vaccine. Sometimes people who have had the live shingles vaccine can get a shingles type rash. If this happens they should keep the area covered.
If your immune system is severely weakened, you should avoid contact with children who have had the flu vaccine as a nasal spray as this is a live vaccine. This is for 2 weeks following their vaccination.
Babies have the live rotavirus vaccine. The virus is in the baby’s poo for about 2 weeks and could make you ill if your immunity is low. Get someone else to change their nappies during this time if you can. If this isn't possible, wash your hands well after changing their nappy.
