Description
A recombinant humanized monoclonal IgG1 antibody that binds to and inhibits the biologic activity of human vascular endothelial growth factor (VEGF). Bevacizumab contains human framework regions and the complementarity-determining regions of a murine antibody that binds to VEGF. Bevacizumab is produced in a Chinese Hamster Ovary mammalian cell expression system in a nutrient medium containing the antibiotic gentamicin and has a molecular weight of approximately 149 kilodaltons.
Indication
As part of combination therapy for metastatic colorectal cancer and HER2-negative metastatic breast cancer.
Mechanism of Action
Bevacizumab contains human framework regions with antigen binding regions of a humanised murine antibody that binds to VEGF. Bevacizumab is produced by recombinant DNA technology in a Chinese hamster ovary mammalian cell expression system in a nutrient medium containing the antibiotic gentamicin and is purified by a process that includes specific viral inactivation and removal steps. Bevacizumab binds VEGF and prevents the interaction of VEGF to its receptors (Flt-1 and KDR) on the surface of endothelial cells. This prevents blood vessel proliferation and in response retardation of metastatic tumor growth occurs.
Clearance
* 0.26 L/day [Male patients who received 1 to 20 mg/kg of Avastin weekly, every 2 weeks, or every 3 weeks] * 0.21 L/day [Female patients who received 1 to 20 mg/kg of Avastin weekly, every 2 weeks, or every 3 weeks] * 0.25 L/day [Patients with higher tumor burden who received 1 to 20 mg/kg of Avastin weekly, every 2 weeks, or every 3 weeks] * 0.2 L/day [patients with tumor burdens below the median who received 1 to 20 mg/kg of Avastin weekly, every 2 weeks, or every 3 weeks] Clearance varies by body weight, gender, and tumor burden. Increased clearance observed in men and in patients with higher tumor burden; however, no evidence of reduced efficacy.
