1. What VITRAKVI is and what it is used for

What VITRAKVI is used for

VITRAKVI contains the active substance larotrectinib.

It is used in adults, adolescents and children to treat solid tumours (cancer) in various parts of the body that are caused by a change in the NTRK gene (neurotrophic tyrosine receptor kinase).

VITRAKVI is only used when

  • these cancers are advanced or have spread to other parts of the body or if a surgery to remove the cancer is likely to cause severe complications and
  • there are no satisfactory treatment options.

Before you are given VITRAKVI, your doctor will do a test to check if you have the change in the NTRK gene.

How VITRAKVI works

In patients whose cancer is due to an altered NTRK gene, the change in the gene causes the body to make an abnormal protein called TRK fusion protein, which can lead to uncontrolled cell growth and cancer. VITRAKVI blocks the action of TRK fusion proteins and so may slow or stop the growth of the cancer. It may also help to shrink the cancer.

If you have any questions on how VITRAKVI works or why it has been prescribed for you, ask your doctor, pharmacist or nurse.

2. What you need to know before you take VITRAKVI

Do not take VITRAKVI if

  • you are allergic to larotrectinib or any of the other ingredients of this medicine (listed in section 6).

Tests and checks

VITRAKVI can increase the amount of the liver enzymes ALT and AST in your blood. Your doctor will do blood tests before and during treatment to check the level of ALT and AST and check how well your liver is working.

Other medicines and VITRAKVI

Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines. This is because some medicines may affect the way VITRAKVI works or VITRAKVI may affect how other medicines work.

Taking VITRAKVI with food and drink

Do not eat grapefruit or drink grapefruit juice while taking VITRAKVI. This is because it may increase the amount of VITRAKVI in your body.

Pregnancy and breast-feeding

Pregnancy

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

You should not use VITRAKVI during pregnancy since the effect of VITRAKVI on the unborn is not known.

Breast-feeding

Do not breast-feed while taking this medicine and for 3 days after the last dose. This is because it is not known if VITRAKVI passes into breast milk.

Contraception – for men and women

You should avoid getting pregnant while taking this medicine.

If you are able to become pregnant, your doctor should do a pregnancy test before you start treatment. You must use effective methods of contraception while taking VITRAKVI and for at least 1 month after the last dose, if

  • you are able to become pregnant. If you use hormonal contraceptives, you should also use a barrier method, such as a condom.
  • you have sex with a woman able to become pregnant.

Ask your doctor about the best method of contraception for you.

Driving, cycling and using machines

VITRAKVI may make you feel dizzy or tired. If this happens, do not drive, cycle or use any tools or machines.

VITRAKVI contains:

  • sucrose: it may be harmful to the teeth. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
  • 22 mg sorbitol in 1 mL. Sorbitol is a source of fructose. If your doctor has told you that you or your child have an intolerance to some sugars or if you have been diagnosed with hereditary fructose intolerance (HFI), a rare genetic disorder in which a person cannot break down fructose, talk to your doctor before you or your child take or receive this medicine.
  • less than 1 mmol (or 23 mg) of sodium per 5 mL, that is to say essentially ‘sodium free’.
