ADVERSE REACTIONS

Clinical Trial Experience

Renal Injury

  1. A retrospective analysis across clinical trials where 5805 patients had received Avastin and chemotherapy and 3713 had received chemotherapy alone has shown higher rates of elevated serum creatinine levels (ranging between 1.5 – 1.9 times baseline levels) in patients who had received Avastin. Creatinine levels did not return to baseline in approximately one-third of patients who received Avastin

WARNINGS AND PRECAUTIONS

Embryo-fetal Toxicity section added
  • Avastin may cause fetal harm based on the drug’s mechanism of action and findings from animal studies. Congenital malformations were observed with the administration of bevacizumab to pregnant rabbits during organogenesis every 3 days at a dose as low as a clinical dose of 10 mg/kg. Furthermore, animal models link angiogenesis and VEGF and VEGF Receptor 2 (VEGFR2) to critical aspects of female reproduction, embryo-fetal development, and postnatal development. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with and for 6 months after the last dose of Avastin. [See Use in Specific Populations (8.1, 8.3), Clinical Pharmacology (12.1).]

ADVERSE REACTIONS

Immunogenicity
  • As with all therapeutic proteins, there is a potential for an immune response to Avastin. In clinical trials of adjuvant colon carcinoma, 14 of 2233 evaluable patients (0.63%) tested positive for treatment-emergent anti-bevacizumab antibodies detected by an electrochemiluminescent (ECL) based assay. Among these 14 patients, three tested positive for neutralizing antibodies against  bevacizumab using an enzyme-linked immunosorbent assay (ELISA). The clinical significance of these anti-product antibody responses to bevacizumab is unknown.
