Chemotherapy and Its Side Effects: Chapter 2 - Monoclonal antibodies (Cont'd)

G.2. Bevacizumab (Avastin)

 

Angiogenesis is a normal physiological process related to the growth of new blood vessels from pre-existing vessels. Angiogenesis can be stimulated as a result of tumor growth. Therefore, modulating the abnormally high angiogenesis has become a strategy for anticancer research after Judah Folkman proposed the theory in 1971.


Bevacizumab is the first approved angiogenesis inhibitor in the U.S. It is a humanized monoclonal antibody that works by blocking vascular endothelial growth factor A (VEGF-A).

Bevacizumab, in combination with intravenous 5-FU–based chemotherapy, was approved by the FDA for first- or second-line treatment of patients with metastatic colorectal cancer in 2004. It was subsequently approved for lung cancer (2006) and breast cancer (2008).

Major side effects of bevacizumab includes hypertension, surgery wound healing problem, higher risk of bleeding, thrombocytopenia, gastrointestinal perforation, and nasal septum perforation. Other common side effects include lower white blood cell (WBC) count, vomiting, constipation, diarrhea, and hair loss.
