Bevacizumab
Pronunciation
Definition 1
A drug used to treat glioblastoma (a type of brain cancer) and certain types of colorectal cancer, lung cancer, and kidney cancer. It is also being studied in the treatment of other types of cancer. Bevacizumab binds to a protein called vascular endothelial growth factor (VEGF). This may prevent the growth of new blood vessels that tumors need to grow. It is a type of antiangiogenesis agent and a type of monoclonal antibody. Also called Avastin. (NCI Dictionary)
Definition 2
A recombinant humanized monoclonal antibody directed against the vascular endothelial growth factor (VEGF), a pro-angiogenic cytokine. Bevacizumab binds to VEGF and inhibits VEGF receptor binding, thereby preventing the growth and maintenance of tumor blood vessels. (NCI Thesaurus)
