Monoclonal antibodies can block these receptors and prevent the growth signal from getting through. Cetuximab (Erbitux), a monoclonal antibody approved to treat colon cancer and head and neck cancers, attaches to receptors on cancer cells that accept a certain growth signal (epidermal growth factor).he cancer cells then ingest the antibody, which releases a few molecules of chemotherapy. The chemotherapy only damages the cancer cells, leaving the surrounding healthy cells undamaged. A number of monoclonal antibody drugs are available to treat various types of cancer.
