What is it and how is it used?

Vectibix is used in the treatment of metastatic colorectal carcinoma (cancer of the bowel) after failure of chemotherapy (medicines used to treat cancer) treatment.

Vectibix is for use in adults 18 years and over.

Vectibix contains the active substance panitumumab, which belongs to a group of medicines called monoclonal antibodies. Monoclonal antibodies are proteins, which specifically recognise and attach (bind) to other unique proteins in the body.

Panitumumab recognises and binds specifically to a protein known as epidermal growth factor receptor (EGFR), which is found on the surface of some cancer cells. When growth factors (other body proteins) attach to the EGFR, the cancer cell is stimulated to grow and divide. Panitumumab binds onto the EGFR and prevents the cancer cell from receiving the messages it needs for growth and division.
