What is encorafenib?

Encorafenib is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Encorafenib is used in combination with another medicine called binimetinib (Mektovi) to treat melanoma (skin cancer) in people who have a "BRAF" gene mutation. These medicines are for use in treating melanoma that cannot be treated with surgery or has spread to other parts of the body.
