## What is lenvatinib?

Lenvatinib is a kinase inhibitor used to treat certain types of cancer. Kinase inhibitors are enzyme inhibitors that blocks the action of one or more protein kinases.

Lenvatinib is used to treat thyroid cancer. It is usually given after radioactive iodine has been tried without success.

Lenvatinib is used together with everolimus (Afinitor) to treat advanced kidney cancer when other medicines have not been effective.

Lenvatinib is used together with pembrolizumab (Keytruda) to treat a certain type of endometrial cancer (a type of uterine cancer) that has progressed and cannot be removed with surgery or radiation.

Lenvatinib is also used to treat liver cancer that cannot be removed with surgery.
