Bevacizumab is part of a group of medications known as monoclonal antibodies. The drug is an antibody that is designed to bind to and inhibit vascular endothelial growth factor (VEGF). VEGF is a naturally occurring protein that encourages the growth of new blood vessels (including those that feed cancers). By binding to VEGF, bevacizumab prevents this protein from encouraging new blood vessel growth, essentially helping to "starve" the cancer of its blood supply. Because the drug does not directly kill cells, it is not considered a chemotherapy medication and does not cause many of the usual chemotherapy side effects. However, it is approved only to be used in combination with chemotherapy.
