Targeted Cancer Therapy

Bevixa 100 mg/4 ml binds VEGF and prevents the interaction of VEGF to its receptors (Flt-1 and KDR) on the surface of endothelial cells. The interaction of VEGF with its receptors leads to endothelial cell proliferation and new blood vessel formation in in vitro models of angiogenesis. Administration of Bevixa 100 mg/4 ml to xenotransplant models of colon cancer in nude (athymic) mice caused reduction of microvascular growth and inhibition of metastatic disease progression.

Targeted Cancer Therapy

Bevixa 100 mg/4 ml is a recombinant humanized monoclonal IgG1 antibody that binds to and inhibits the biologic activity of human vascular endothelial growth factor (VEGF) in-vitro and in-vivo assay systems. Bevixa 100 mg/4 ml contains human framework regions and the complementarity-determining regions of a murine antibody that binds to VEGF. Bevixa 100 mg/4 ml has an approximate molecular weight of 149 kD. Bevixa 100 mg/4 ml is produced in a mammalian cell (Chinese Hamster Ovary) expression system in a nutrient medium containing the antibiotic gentamicin. Gentamicin is not detectable in the final product. Bevixa 100 mg/4 ml is a clear to slightly opalescent, colorless to pale brown, sterile, pH 6.2 solution for intravenous infusion.

Pregnancy: Bevixa 100 mg/4 ml may cause fetal harm based on findings from animal studies and the drug’s mechanism of action.Lactation: No data are available regarding the presence of Bevixa 100 mg/4 ml in human milk, the effects on the breast fed infant, or the effects on milk production. Human IgG is present in human milk, but published data suggest that breast milk antibodies do not enter the neonatal and infant circulation in substantial amounts. Because of the potential for serious adverse reactions in breastfed infants from Bevixa 100 mg/4 ml, advise a nursing woman that breastfeeding is not recommended during treatment with Bevixa 100 mg/4 ml.

Pediatric Use: The safety, effectiveness and pharmacokinetic profile of Bevixa 100 mg/4 ml in pediatric patients have not been established. In published literature reports, cases of non-mandibular osteonecrosis have been observed in patients under the age of 18 years who have received Bevixa 100 mg/4 ml. Bevixa 100 mg/4 ml is not approved for use in patients under the age of 18 years. Antitumor activity was not observed among eight children with relapsed glioblastoma treated with Bevixa 100 mg/4 ml and irinotecan. There is insufficient information to determine the safety and efficacy of Bevixa 100 mg/4 ml in children with glioblastoma. Animal Data Juvenile cynomolgus monkeys with open growth plates exhibited physeal dysplasia following 4 to 26 weeks exposure at 0.4 to 20 times the recommended human dose (based on mg/kg and exposure). The incidence and severity of physeal dysplasia were dose-related and were partially reversible upon cessation of treatment.Geriatric Use In Study: Severe adverse events that occurred at a higher incidence (≥2%) in patients aged ≥65 years as compared to younger patients were asthenia, sepsis, deep thrombophlebitis, hypertension, hypotension, myocardial infarction, congestive heart failure, diarrhea, constipation, anorexia, leukopenia, anemia, dehydration, hypokalemia, and hyponatremia. The effect of Bevixa 100 mg/4 ml on overall survival was similar in elderly patients as compared to younger patients.
