Cabozantinib (Cabometyx)

The basics

Cabozantinib (brand name – Cabometyx, Cometriq) is an FDA-approved treatment for kidney, ovaries, liver, and thyroid cancers. It is used in combination with nivolumab (Opdivo) to treat kidney cancers. Cabozantinib is used in adults and children 12 years of age and older for cancers that have spread to nearby tissues or other parts of the body.

Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
