and what it is used for<\/h2>\n\n\n\n<p><strong>What VITRAKVI is used for<\/strong><\/p>\n\n\n\n<p>VITRAKVI contains the active substance larotrectinib.<\/p>\n\n\n\n<p>The medicine is used for adults, adolescents, and children to treat solid\u00a0tumors\u00a0(cancer) in various places in the body and which are caused by a change in the NTRK gene (neurotrophic tyrosine\u00a0receptor\u00a0kinase).<\/p>\n\n\n\n<p>VITRAKVI is used only when<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>these&nbsp;tumors&nbsp;are advanced or have spread to other parts of the body or if an operation to remove the cancer is likely to cause serious complications&nbsp;<strong>and<\/strong><\/li><li>there is no satisfactory treatment option.<\/li><\/ul>\n\n\n\n<p>Before you receive VITRAKVI, the doctor will do a test to check if you carry the change in the&nbsp;<em>NTRK<\/em>&nbsp;gene.<\/p>\n\n\n\n<p><strong>How VITRAKVI works<\/strong><\/p>\n\n\n\n<p>In patients whose cancer is caused by a changed\u00a0<em>NTRK<\/em>\u00a0gene, the gene change causes the body to produce an abnormal\u00a0protein, the so-called TRK fusion protein, which can lead to uncontrolled cell growth and cancer.\u00a0VITRAKVI blocks the action of the TRK fusion proteins and can thus delay or stop cancer&#8217;s growth.\u00a0It can also help\u00a0shrink a\u00a0tumor.<\/p>\n\n\n\n<p>If you have any questions about how VITRAKVI works or why it has been prescribed for you, ask your doctor, pharmacist, or nurse.<br><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What you need to know before you take VITRAKVI<\/h2>\n\n\n\n<h2 class=\"wp-block-heading\">Do not take VITRAKVI<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>if you are allergic to larotrectinib or any of the other ingredients of this medicine (listed in section 6).<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Tests and checks<\/h2>\n\n\n\n<p>VITRAKVI can cause the amount of the liver enzymes&nbsp;ALT&nbsp;and&nbsp;AST&nbsp;in your blood to increase.&nbsp;The doctor takes blood samples before and during treatment to check the levels of&nbsp;ALT&nbsp;and&nbsp;AST&nbsp;in the blood and check how well your liver is working.<a><\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other medicines and VITRAKVI<\/h2>\n\n\n\n<p>Tell your doctor, pharmacist, or nurse if you are taking, have recently taken, or might take any other medicines, as some medicines can affect how VITRAKVI works.\u00a0Conversely, VITRAKVI can affect how other medicines work.<\/p>\n\n\n\n<p>You must tell your doctor, pharmacist, or nurse if you are taking any of the following medicines:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>itraconazole, voriconazole, clarithromycin, telithromycin, and troleandomycin for the treatment of fungal
