5 WARNINGS AND PRECAUTIONS • Gastrointestinal Perforations and Fistula: Discontinue for gastrointestinal perforations, tracheoesophageal fistula, grade 4 fistula, or fistula formation involving any organ. ( 5.1 ) • Surgery and Wound Healing Complications: In patients who experience wound healing complications during ZIRABEV treatment, withhold ZIRABEV until adequate wound healing. Withhold for at least 28 days prior to elective surgery. Do not administer ZIRABEV for at least 28 days following a major surgery, and until adequate wound healing. The safety of resumption of bevacizumab products after resolution of wound healing complication has not been established. Discontinue for wound healing complications of necrotizing fasciitis. ( 5.2 ) • Hemorrhage: Severe or fatal hemorrhages have occurred. Do not administer for recent hemoptysis. Discontinue for Grade 3–4 hemorrhage. ( 5.3 ) • Arterial Thromboembolic Events (ATE): Discontinue for severe ATE. ( 5.4 ) • Venous Thromboembolic Events (VTE): Discontinue for Grade 4 VTE. ( 5.5 ) • Hypertension: Monitor blood pressure and treat hypertension. Withhold if not medically controlled; resume once controlled. Discontinue for hypertensive crisis or hypertensive encephalopathy. ( 5.6 ) • Posterior Reversible Encephalopathy Syndrome (PRES): Discontinue. ( 5.7 ) • Renal Injury and Proteinuria: Monitor urine protein. Discontinue for nephrotic syndrome. Withhold until less than 2 grams of protein in urine. ( 5.8 ) • Infusion–Related Reactions: Decrease rate for infusion-related reactions. Discontinue for severe infusion-related reactions and administer medical therapy. ( 5.9 ) • Embryo-Fetal Toxicity: May cause fetal harm. Advise females of potential risk to fetus and need for use of effective contraception. ( 5.10 , 8.1 , 8.3 ) • Ovarian Failure: Advise females of the potential risk. ( 5.11 , 8.3 ) • Congestive Heart Failure (CHF): Discontinue ZIRABEV in patients who develop CHF. ( 5.12 ) 5.1 Gastrointestinal Perforations and Fistulae Serious and sometimes fatal gastrointestinal perforation occurred at a higher incidence in patients receiving bevacizumab products compared to patients receiving chemotherapy. The incidence ranged from 0.3% to 3% across clinical studies, with the highest incidence in patients with a history of prior pelvic radiation. Perforation can be complicated by intra-abdominal abscess, fistula formation, and the need for diverting ostomies. The majority of perforations occurred within 50 days of the first dose [see Adverse Reactions (6.1) ] . Serious fistulae (including, tracheoesophageal, bronchopleural, biliary, vaginal, renal and bladder sites) occurred at a higher incidence in patients receiving bevacizumab products compared to patients receiving chemotherapy. The incidence ranged from <1% to 1.8% across clinical studies, with the highest incidence in patients with cervical cancer. The majority of fistulae occurred within 6 months of the first dose. Patients who develop a gastrointestinal vaginal fistula may also have a bowel obstruction and require surgical intervention, as well as a diverting ostomy. Avoid ZIRABEV in patients with ovarian cancer who have evidence of recto-sigmoid involvement by pelvic examination or bowel involvement on CT scan or clinical symptoms of bowel obstruction. Discontinue in patients who develop gastrointestinal perforation, tracheoesophageal fistula or any Grade 4 fistula. Discontinue in patients with fistula formation involving any internal organ . 5.2 Surgery and Wound Healing Complications In a controlled clinical study in which bevacizumab was not administered within 28 days of major surgical procedures, the incidence of wound healing complications, including serious and fatal complications, was 15% in patients with mCRC who underwent surgery while receiving bevacizumab and 4% in patients who did not receive bevacizumab. In a controlled clinical study in patients with relapsed or recurrent GBM, the incidence of wound healing events w…

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.

8.1 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.

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.
