The safety data in Warnings and Precautions and described below reflect exposure to bevacizumab in 4463 patients including those with mCRC (AVF2107g, E3200), non-squamous NSCLC (E4599), GBM (EORTC 26101), mRCC (BO17705), cervical cancer (GOG-0240), epithelial ovarian, fallopian tube, or primary peritoneal cancer (MO22224, AVF4095, GOG-0213, and GOG-0218) or another cancer at the recommended dose and schedule for a median of 6 to 23 doses. The most common adverse reactions observed in patients receiving bevacizumab as a single agent or in combination with other anti-cancer therapies at a rate >10% were epistaxis, headache, hypertension, rhinitis, proteinuria, taste alteration, dry skin, hemorrhage, lacrimation disorder, back pain, and exfoliative dermatitis. Across clinical studies, bevacizumab was discontinued in 8% to 22% of patients because of adverse reactions [see Clinical Studies (14) ]. Metastatic Colorectal Cancer In Combination with bolus IFL The safety of bevacizumab was evaluated in 392 patients who received at least one dose of bevacizumab in a double-blind, active-controlled study (AVF2107g), which compared bevacizumab (5 mg/kg every 2 weeks) with bolus-IFL to placebo with bolus IFL in patients with mCRC [see Clinical Studies (14.1) ] . Patients were randomized (1:1:1) to placebo with bolus IFL, bevacizumab with bolus IFL, or bevacizumab with fluorouracil and leucovorin. The demographics of the safety population were similar to the demographics of the efficacy population. All Grades 3–4 adverse reactions and selected Grades 1–2 adverse reactions (i.e., hypertension, proteinuria, thromboembolic events) were collected in the entire study population. Adverse reactions are presented in Table 2.

7 DRUG INTERACTIONS Effects of ZIRABEV on Other Drugs No clinically meaningful effect on the pharmacokinetics of irinotecan or its active metabolite SN38, interferon alfa, carboplatin or paclitaxel was observed when bevacizumab was administered in combination with these drugs; however, 3 of the 8 patients receiving bevacizumab with paclitaxel and carboplatin had lower paclitaxel exposure after four cycles of treatment (at Day 63) than those at Day 0, while patients receiving paclitaxel and carboplatin alone had a greater paclitaxel exposure at Day 63 than at Day 0.

8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on findings from animal studies and their mechanism of action [see Clinical Pharmacology (12.1) ] , bevacizumab products may cause fetal harm in pregnant women. Limited postmarketing reports describe cases of fetal malformations with use of bevacizumab products in pregnancy; however, these reports are insufficient to determine drug associated risks. In animal reproduction studies, intravenous administration of bevacizumab to pregnant rabbits every 3 days during organogenesis at doses approximately 1 to 10 times the clinical dose of 10 mg/kg produced fetal resorptions, decreased maternal and fetal weight gain and multiple congenital malformations including corneal opacities and abnormal ossification of the skull and skeleton including limb and phalangeal defects (see Data ) . Furthermore, animal models link angiogenesis and VEGF and VEGFR2 to critical aspects of female reproduction, embryo-fetal development, and postnatal development. Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Pregnant rabbits dosed with 10 mg/kg to 100 mg/kg bevacizumab (approximately 1 to 10 times the clinical dose of 10 mg/kg) every three days during the period of organogenesis (gestation day 6–18) exhibited decreases in maternal and fetal body weights and increased number of fetal resorptions. There were dose-related increases in the number of litters containing fetuses with any type of malformation (42% for the 0 mg/kg dose, 76% for the 30 mg/kg dose, and 95% for the 100 mg/kg dose) or fetal alterations (9% for the 0 mg/kg dose, 15% for the 30 mg/kg dose, and 61% for the 100 mg/kg dose). Skeletal deformities were observed at all dose levels, with some abnormalities including meningocele observed only at the 100 mg/kg dose level. Teratogenic effects included: reduced or irregular ossification in the skull, jaw, spine, ribs, tibia and bones of the paws; fontanel, rib and hindlimb deformities; corneal opacity; and absent hindlimb phalanges. 8.2 Lactation Risk Summary No data are available regarding the presence of bevacizumab products 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, advise women not to breastfeed during treatment with ZIRABEV and for 6 months after the last dose. 8.3 Females and Males of Reproductive Potential Contraception Females Bevacizumab products may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Advise females of reproductive potential to use effective contraception during treatment with ZIRABEV and for 6 months after the last dose. Infertility Females Bevacizumab products increase the risk of ovarian failure and may impair fertility. Inform females of reproductive potential of the risk of ovarian failure prior to the first-dose of ZIRABEV. Long-term effects of bevacizumab products on fertility are not known. In a clinical study of 179 premenopausal women randomized to receive chemotherapy with or without bevacizumab, the incidence of ovarian failure was higher in patients who received bevacizumab with chemotherapy (34%) compared to patients who received chemotherapy alone (2%). After discontinuing bevacizumab with chemotherapy, recovery of ovarian function occurred in 22% of these patients [see Warnings and Precautions (5.11) , Adverse Reactions (6.1) ]. 8.4 Pediatric Use The safety and effectiveness of bevacizumab products in pediatric patients have not been established. In published literature re …

12.1 Mechanism of Action Bevacizumab products bind VEGF and prevent 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 bevacizumab to xenotransplant models of colon cancer in nude (athymic) mice caused reduction of microvascular growth and inhibition of metastatic disease progression.
