1. Why am I using TEPMETKO?

TEPMETKO contains the active ingredient tepotinib (as hydrochloride monohydrate). TEPMETKO belongs to anti-cancer medicines called mesenchymal epithelial transition (MET) tyrosine kinase inhibitors.

TEPMETKO has provisional approval to treat adults with non-small cell lung cancer (NSCLC) that has spread to other parts of the body or is advanced, and whose tumours have mesenchymal epithelial transition (MET) exon 14 skipping alterations.

The alterations in the MET gene can lead to a dysfunctional protein which can lead to uncontrolled cell growth and cancer. By blocking this dysfunctional protein, TEPMETKO may slow or stop the cancer from growing. It may also help to shrink the cancer.

2. What should I know before I use TEPMETKO?


Do not use TEPMETKO if:

  • you are allergic to tepotinib, or any of the ingredients listed at the end of this leaflet.

Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • have or have had any new or worsening symptoms indicative of inflammation of the lungs, e.g. sudden breathing difficulties, cough or fever
  • have or have had liver problems
  • take any medicines for any other conditions (see Section 3. What if I am taking other medicines?).

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?
