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
Before you are given VITRAKVI, your doctor will do a test to check if you have the change in the NTRK gene.
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.
VITRAKVI can increase the amount of the liver enzymes ALT and AST and bilirubin in your blood. Your doctor will do blood tests before and during treatment to check the level of ALT, AST and bilirubin and check how well your liver is working.
