May be used with chemotherapy or other targeted therapies depending on cancer type and stage.
Avastin is a monoclonal antibody that binds to vascular endothelial growth factor (VEGF), preventing VEGF from interacting with its receptors on blood vessel cells. This blocks the signaling needed for new blood vessel formation (angiogenesis), effectively starving the tumor of nutrients and oxygen supply.
Administered as IV infusion every 2-3 weeks. Common side effects include hypertension, fatigue, bleeding, and delayed wound healing. Serious risks include gastrointestinal perforation, fistula formation, and arterial thromboembolic events. Requires monitoring of blood pressure and proteinuria during treatment.
