The safety data in Warnings and Precautions and described below reflect exposure to bevacizumab in 4,463 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), or other cancers 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. Table 2: Grades 3 - 4 Adverse Reactions Occurring at Higher Incidence (≥2%) in Patients Receiving Bevacizumab vs. Placebo in Study AVF2107g Adverse Reaction a Bevacizumab with IFL (N=392) Placebo with IFL (N=396) Hematology Leukopenia 37% 31% Neutropenia 21% 14% Gastrointestinal Diarrhea 34% 25% Abdominal pain 8% 5% Constipation 4% 2% Vascular Hypertension 12% 2% Deep vein thrombosis 9% 5% Intra-abdominal thrombosis 3% 1% Syncope 3% 1% General Asthenia 10% 7% Pain 8% 5% a NCI-CTC version 3 In Combination with FOLFOX4 The safety of bevacizumab was evaluated in 521 patients in an open-label, active-controlled study (E3200) in patients who were previously treated with irinotecan and fluorouracil for initial therapy for mCRC. Patients were randomized (1:1:1) to FOLFOX4, bevacizumab (10 mg/kg every 2 weeks prior to FOLFOX4 on Day 1) with FOLFOX4, or bevacizumab alone (10 mg/kg every 2 weeks). Bevacizumab was continued until disease progression or unacceptable toxicity. The demographics of the safety population were similar to the demographics of the efficacy population. Selected Grades 3 - 5 non-hematologic and Grades 4 to 5 hematologic occurring at a higher incidence (≥ 2%) in patients receiving bevacizumab with FOLFOX4 compared to FOLFOX4 alone were fatigue (19% vs. 13%), diarrhea (18% vs. 13%), sensory neuropathy (17% vs. 9%), nausea (12% vs. 5%), vomiting (11% vs. 4%), dehydration (10% vs. 5%), hypertension (9% vs. 2%), abdominal pain (8% vs. 5%), hemorrhage (5% vs. 1%), other neurological (5% vs. 3%), ileus (4% vs. 1%) and headache (3% vs. 0%). These data are likely to under-estimate the true adverse reaction rates due to the reporting mechanisms. First-Line Non Squamous Non-Small Cell Lung Cancer The safety of bevacizumab was evaluated as first-line treatment in 422 patients with unresectable NSCLC who received at least one dose of bevacizumab in an active-controlled, open-label, multicenter trial (E4599) [see Clinical Studies (14.3)] . Chemotherapy naïve patients with locally advanced, metastatic or recurrent non–squamous NSCLC were randomized (1:1) to receive six 21-day cycles of paclitaxel and carboplatin with or without bevacizumab (15 mg/kg every 3 weeks). After completion or upon discontinuation of chemotherapy, patients randomized to receive bevacizumab continued to receive bevacizumab alone until disease progression or until unacceptable toxicity. The trial excluded patients with predominant squamous histology (mixed cell type tumors only), CNS metastasis, gross hemoptysis (1/2 teaspoon or more of red blood), unstable angina, or receiving therapeutic anticoagulation. The demographics of the safety population were similar to the demographics of the efficacy population. Only Grades 3 - 5 non-hematologic and Grades 4 - 5 hematologic adverse reactions were collected. Grades 3 - 5 non-hematologic and Grades 4 - 5 hematologic adverse reactions occurring at a higher incidence (≥ 2%) in patients receiving bevacizumab with paclitaxel and carboplatin compared with patients receiving chemotherapy alone were neutropenia (27% vs. 17%), fatigue (16% vs. 13%), hypertension (8% vs. 0.7%), infection without neutropenia (7% vs. 3%), venous thromboembolism (5% vs. 3%), febrile neutropenia (5% vs. 2%), pneumonitis/pulmonary infiltrates (5% vs. 3%), infection with Grade 3 or 4 neutropenia (4% vs. 2%), hyponatremia (4% vs. 1%), headache (3% vs. 1%) and proteinuria (3% vs. 0%). Recurrent Glioblastoma The safety of bevacizumab was evaluated in a multicenter, randomized, open-label study (EORTC 26101) in patients with recurrent GBM following radiotherapy and temozolomide of whom 278 patients received at least one dose of bevacizumab and are considered safety evaluable [see Clinical Studies (14.4)] . Patients were randomized (2:1) to receive bevacizumab (10 mg/kg every 2 weeks) with lomustine or lomustine alone until disease progression or unacceptable toxicity. The demographics of the safety population were similar to the demographics of the efficacy population. In the bevacizumab with lomustine arm, 22% of patients discontinued treatment due to adverse reactions compared with 10% of patients in the lomustine arm. In patients receiving bevacizumab with lomustine, the adverse reaction profile was similar to that observed in other approved indications. Metastatic Renal Cell Carcinoma The safety of bevacizumab was evaluated in 337 patients who received at least one dose of bevacizumab in a multicenter, double-blind study (BO17705) in patients with mRCC. Patients who had undergone a nephrectomy were randomized (1:1) to receive either bevacizumab (10 mg/kg every 2 weeks) or placebo with interferon alfa [see Clinical Studies (14.5)] . Patients were treated until disease progression or unacceptable toxicity. The demographics of the safety population were similar to the demographics of the efficacy population. Grades 3 - 5 adverse reactions occurring at a higher incidence (>2%) were fatigue (13% vs. 8%), asthenia (10% vs. 7%), proteinuria (7% vs. 0%), hypertension (6% vs. 1%; including hypertension and hypertensive crisis), and hemorrhage (3% vs. 0.3%; including epistaxis, small intestinal hemorrhage, aneurysm ruptured, gastric ulcer hemorrhage, gingival bleeding, hemoptysis, hemorrhage intracranial, large intestinal hemorrhage, respiratory tract hemorrhage, and traumatic hematoma). Adverse reactions are presented in Table 3.

Persistent, Recurrent, or Metastatic Cervical Cancer The safety of bevacizumab was evaluated in 218 patients who received at least one dose of bevacizumab in a multicenter study (GOG-0240) in patients with persistent, recurrent, or metastatic cervical cancer [see Clinical Studies (14.6)] . Patients were randomized (1:1:1:1) to receive paclitaxel and cisplatin with or without bevacizumab (15 mg/kg every 3 weeks), or paclitaxel and topotecan with or without bevacizumab (15 mg/kg every 3 weeks). The demographics of the safety population were similar to the demographics of the efficacy population. Grades 3 - 4 adverse reactions occurring at a higher incidence (≥ 2%) in 218 patients receiving bevacizumab with chemotherapy compared to 222 patients receiving chemotherapy alone were abdominal pain (12% vs. 10%), hypertension (11% vs. 0.5%), thrombosis (8% vs. 3%), diarrhea (6% vs. 3%), anal fistula (4% vs. 0%), proctalgia (3% vs. 0%), urinary tract infection (8% vs. 6%), cellulitis (3% vs. 0.5%), fatigue (14% vs. 10%), hypokalemia (7% vs. 4%), hyponatremia (4% vs. 1%), dehydration (4% vs. 0.5%), neutropenia (8% vs. 4%), lymphopenia (6% vs. 3%), back pain (6% vs. 3%), and pelvic pain (6% vs. 1%). Adverse reactions are presented in Table 4.

Patients were randomized to receive bevacizumab 10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks. Patients had received no more than 2 prior chemotherapy regimens. The trial excluded patients with evidence of recto-sigmoid involvement by pelvic examination or bowel involvement on CT scan or clinical symptoms of bowel obstruction. Patients were treated until disease progression or unacceptable toxicity. Forty percent of patients on the chemotherapy alone arm received bevacizumab alone upon progression. The demographics of the safety population were similar to the demographics of the efficacy population. Grades 3 - 4 adverse reactions occurring at a higher incidence ( ≥ 2%) in 179 patients receiving bevacizumab with chemotherapy compared to 181 patients receiving chemotherapy alone were hypertension (6.7% vs. 1.1%) and palmar-plantar erythrodysaesthesia syndrome (4.5% vs. 1.7%). Adverse reactions are presented in Table 6. Table 6: Grades 2 - 4 Adverse Reactions Occurring at Higher Incidence (≥ 5%) in Patients Receiving Bevacizumab with Chemotherapy vs. Chemotherapy Alone in Study MO22224 Adverse Reaction a Bevacizumab with Chemotherapy (N=179) Chemotherapy (N=181) Hematology Neutropenia 31% 25% Vascular Hypertension 19% 6% Nervous system Peripheral sensory neuropathy 18% 7% General Mucosal inflammation 13% 6% Renal and urinary Proteinuria 12% 0.6% Skin and subcutaneous tissue Palmar-plantar erythrodysaesthesia 11% 5% Infections Infection 11% 4% Respiratory, thoracic and mediastinal Epistaxis 5% 0% a NCI-CTC version 3 6.2 Immunogenicity As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and the specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other bevacizumab products may be misleading. In clinical studies for adjuvant treatment of a solid tumor, 0.6% (14/2233) of patients tested positive for treatment-emergent anti-bevacizumab antibodies as 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-bevacizumab antibodies is not known. 6.3 Postmarketing Experience The following adverse reactions have been identified during postapproval use of bevacizumab products. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General: Polyserositis Cardiovascular: Pulmonary hypertension, Mesenteric venous occlusion Gastrointestinal: Gastrointestinal ulcer, Intestinal necrosis, Anastomotic ulceration Hemic and lymphatic: Pancytopenia Hepatobiliary disorders: Gallbladder perforation Musculoskeletal and Connective Tissue Disorders: Osteonecrosis of the jaw Renal: Renal thrombotic microangiopathy (manifested as severe proteinuria) Respiratory: Nasal septum perforation Vascular: Arterial (including aortic) aneurysms, dissections, and rupture

12.3 Pharmacokinetics The pharmacokinetic profile of bevacizumab was assessed using an assay that measures total serum bevacizumab concentrations (i.e., the assay did not distinguish between free bevacizumab and bevacizumab bound to VEGF ligand). Based on a population pharmacokinetic analysis of 491 patients who received 1 to 20 mg/kg of bevacizumab every week, every 2 weeks, or every 3 weeks, bevacizumab pharmacokinetics are linear and the predicted time to reach more than 90% of steady state concentration is 84 days. The accumulation ratio following a dose of 10 mg/kg of bevacizumab once every 2 weeks is 2.8. Population simulations of bevacizumab exposures provide a median trough concentration of 80.3 mcg/mL on Day 84 (10 th , 90 th percentile: 45, 128) following a dose of 5 mg/kg once every two weeks. Distribution The mean (% coefficient of variation [CV%]) central volume of distribution is 2.9 (22%) L. Elimination The mean (CV%) clearance is 0.23 (33) L/day. The estimated half-life is 20 days (11 to 50 days). Specific Populations The clearance of bevacizumab varied by body weight, sex, and tumor burden. After correcting for body weight, males had a higher bevacizumab clearance (0.26 L/day vs. 0.21 L/day) and a larger central volume of distribution (3.2 L vs. 2.7 L) than females. Patients with higher tumor burden (at or above median value of tumor surface area) had a higher bevacizumab clearance (0.25 L/day vs. 0.20 L/day) than patients with tumor burdens below the median. In Study AVF2107g, there was no evidence of lesser efficacy (hazard ratio for overall survival) in males or patients with higher tumor burden treated with bevacizumab as compared to females and patients with low tumor burden.
