Patient Info Service - information for patients

1. What is Vectibix and what is it used for?

Vectibix is ​​used in the treatment of metastatic colorectal cancer (colon cancer) in adult patients with a type of tumor called "RAS-Wild-type tumor "is known. Vectibix is ​​used alone or in combination with other cancer medicines.

Vectibix contains the active substance panitumumab, which belongs to a group of medicines called monoclonal antibodies. Monoclonal antibodies are proteins that specifically recognize certain other proteins in the body and bind to them.

Panitumumab specifically recognizes and binds to a protein called "epidermal growth factor receptor (EGFR = Epidermal Growth Factor Receptor)", which is found on the surface of some cancer cells. When growth factors (other body proteins) bind to EGFR, the cancer cell is stimulated to grow and divide. Panitumumab binds to the EGFR, preventing the cancer cell from receiving the signals it needs to grow and divide.
