What is tepotinib?

Tepotinib is used to treat a certain type of non-small cell lung cancer that has a specific genetic marker (an abnormal "MET" gene). Your doctor will test you for this gene.

Tepotinib was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, some people responded to tepotinib, but further studies are needed.
