Patient information leaflet

What is it and what is it used for?

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.

What should you consider before use?

Do not use Vectibix
  • if you have ever had a severe or life-threatening allergic (hypersensitivity) reaction to panitumumab or any of the other ingredients of Vectibix.
  • if you have previously had or have evidence of interstitial pneumonitis (swelling of the lungs causing coughing and difficulty breathing) or pulmonary fibrosis (scarring and thickening in the lungs with shortness of breath).
Take special care with Vectibix

Your doctor will check your blood levels of several substances such as magnesium, and other electrolyte levels such as calcium and potassium in your blood before you start Vectibix treatment. If these levels are too low, your doctor may prescribe you appropriate supplements.

Your doctor will ask you to come in for tests to monitor hypomagnesaemia (low magnesium levels in the blood) and hypocalcaemia (low calcium levels in the blood) periodically during your treatment, and for up to 8 weeks after you have finished your treatment.
