Cetuximab (Erbitux®)

Cetuximab

Brand Name: Erbitux®

Cetuximab is used to treat a certain type of head and neck cancer, and colorectal cancer. More specifically, cetuximab may be used alone or in combination with another medication to treat a certain type of colon or rectum cancer that has spread to other parts of the body.

Cetuximab is a monoclonal antibody, which belongs to the type of cancer drugs known as biologics or targeted therapy. This drug works by slowing or stopping the growth of cancer cells.

Given as a liquid, cetuximab is slowly injected, or infused, into a vein. Most often, cetuximab is given once a week.
