What VITRAKVI is used for

VITRAKVI contains the active ingredient larotrectinib.

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

VITRAKVI is only used when

• these cancers are advanced or have spread to other parts of the body or when surgery to remove them would cause severe complicationsand
• there are no satisfactory treatment options.

Before VITRAKVI is started, your doctor will perform a test to determine if you have the NTRK gene change.

How VITRAKVI works

In patients with cancer caused by an NTRK gene alteration, the change in the gene causes the body to produce an abnormal protein called TRK fusion protein, which can cause uncontrolled cell growth and cancer. VITRAKVI blocks the action of TRK fusion proteins and can therefore slow down or stop cancer growth. It may also help reduce its size.

If you have any doubts about how VITRAKVI works or why you have been prescribed it, consult your doctor, pharmacist, or nurse.

Do not take VITRAKVI

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

Analysis and checks

VITRAKVI may increase the levels of liver enzymes ALT and AST and bilirubin in the blood. Your doctor will perform blood tests before treatment and during treatment to check the levels of ALT, AST, and bilirubin and evaluate liver function.
