Describe MOA of bevacizumab.
Monoclonal antibody, VEGF inhibitor, inhibits angiogenesis.
VEGF-A interacts with receptor on epithelial cells (VEFG-R2). Bev binds VEGF-A extracellularly, making it unable to activate the receptor.
Absolute contraindications to bevacizumab
surgery within 28 days (especially abdominal or bowel), nephrotic syndrome, existing fistula or wound complication
Indications to discontinue bevacizumab
fistula, bowel perf, heart failure, hemorrhage, HTN crisis, PRES, VTE
