14 CLINICAL STUDIES. 14.1Metastatic Colorectal Cancer. Study AVF2107gThe safety and efficacy of Avastin was evaluated in double-blind, active-controlled study [AVF2107g (NCT00109070)] in 923 patients with previously untreated mCRC who were randomized (1:1:1) to placebo with bolus-IFL (irinotecan 125 mg/m2, fluorouracil 500 mg/m2, and leucovorin 20 mg/m2 given once weekly for weeks every weeks), Avastin (5 mg/kg every weeks) with bolus-IFL, or Avastin (5 mg/kg every weeks) with fluorouracil and leucovorin. Enrollment to the Avastin with fluorouracil and leucovorin arm was discontinued after enrollment of 110 patients in accordance with the protocol-specified adaptive design. Avastin was continued until disease progression or unacceptable toxicity or for maximum of 96 weeks. The main outcome measure was overall survival (OS).The median age was 60 years; 60% were male, 79% were White, 57% had an ECOG performance status of 0, 21% had rectal primary and 28% received prior adjuvant chemotherapy. The dominant site of disease was extra-abdominal in 56% of patients and was the liver in 38% of patients.The addition of Avastin improved survival across subgroups defined by age (< 65 years, >= 65 years) and sex.

Figure 1. Study E3200The safety and efficacy of Avastin were evaluated in randomized, open-label, active-controlled study [E3200 (NCT00025337)] in 829 patients who were previously treated with irinotecan and fluorouracil for initial therapy for metastatic disease or as adjuvant therapy. Patients were randomized (1:1:1) to FOLFOX4 (Day 1: oxaliplatin 85 mg/m2 and leucovorin 200 mg/m2 concurrently, then fluorouracil 400 mg/m2 bolus followed by 600 mg/m2 continuously; Day 2: leucovorin 200 mg/m2, then fluorouracil 400 mg/m2 bolus followed by 600 mg/m2 continuously; every weeks), Avastin (10 mg/kg every weeks prior to FOLFOX4 on Day 1) with FOLFOX4, or Avastin alone (10 mg/kg every weeks). Avastin was continued until disease progression or unacceptable toxicity. The main outcome measure was OS.The Avastin alone arm was closed to accrual after enrollment of 244 of the planned 290 patients following planned interim analysis by the data monitoring committee based on evidence of decreased survival compared to FOLFOX4 alone.The median age was 61 years; 60% were male, 87% were White, 49% had an ECOG performance status of 0, 26% received prior radiation therapy, and 80% received prior adjuvant chemotherapy, 99% received prior irinotecan with or without fluorouracil for metastatic disease, and 1% received prior irinotecan and fluorouracil as adjuvant therapy.The addition of Avastin to FOLFOX4 resulted in significantly longer survival as compared to FOLFOX4 alone; median OS was 13.0 months vs. 10.8 months [hazard ratio (HR) 0.75 (95% CI: 0.63, 0.89), p-value of 0.001 stratified log-rank test] with clinical benefit seen in subgroups defined by age (< 65 years, >= 65 years) and sex. PFS and ORR based on investigator assessment were higher in patients receiving Avastin with FOLFOX4.. Study TRC-0301The activity of Avastin with fluorouracil (as bolus or infusion) and leucovorin was evaluated in single arm study [TRC-0301 (NCT00066846)] enrolling 339 patients with mCRC with disease progression following both irinotecan- and oxaliplatin-based chemotherapy. Seventy-three percent of patients received concurrent bolus fluorouracil and leucovorin. One objective partial response was verified in the first 100 evaluable patients for an ORR of 1% (95% CI: 0%, 5.5%).. Study ML18147The safety and efficacy of Avastin were evaluated in prospective, randomized, open-label, multinational, controlled study [ML18147 (NCT00700102)] in 820 patients with histologically confirmed mCRC who had progressed on first-line Avastin containing regimen. Patients were excluded if they progressed within months of initiating first-line chemotherapy and if they received Avastin for less than consecutive months in the first-line setting. Patients were randomized (1:1) within months after discontinuing Avastin as first-line treatment to receive fluoropyrimidine-irinotecan- or fluoropyrimidine-oxaliplatin-based chemotherapy with or without Avastin (5 mg/kg every weeks or 7.5 mg/kg every weeks). The choice of second-line treatment was contingent upon first-line chemotherapy. Second-line treatment was administered until progressive disease or unacceptable toxicity. The main outcome measure was OS. secondary outcome measure was ORR.The median age was 63 years (21 to 84 years); 64% were male, 52% had an ECOG performance status of 1, 44% had an ECOG performance status of 0, 58% received irinotecan-based therapy as first-line treatment, 55% progressed on first-line treatment within months, and 77% received their last dose of Avastin as first-line treatment within 42 days of being randomized. Second-line chemotherapy regimens were generally balanced between each arm.The addition of Avastin to fluoropyrimidine-based chemotherapy resulted in statistically significant prolongation of OS and PFS. There was no significant difference in ORR. Results are presented in Table 12 and Figure 2.Table 12: Efficacy Results in Study ML18147Efficacy ParameterAvastin with Chemotherapy(N=409)Chemotherapy(N=411)Overall Survivalp=0.0057 by unstratified log-rank test.

Figure 2. 14.2Lack of Efficacy in Adjuvant Treatment of Colon Cancer. Lack of efficacy of Avastin as an adjunct to standard chemotherapy for the adjuvant treatment of colon cancer was determined in two randomized, open-label, multicenter clinical studies.The first study [BO17920 (NCT00112918)] was conducted in 3451 patients with high-risk stage II and III colon cancer, who had undergone surgery for colon cancer with curative intent. Patients were randomized to receive Avastin at dose equivalent to 2.5 mg/kg/week on either 2-weekly schedule with FOLFOX4 (N=1155) or on 3-weekly schedule with XELOX (N=1145) or FOLFOX4 alone (N=1151). The main outcome measure was disease free survival (DFS) in patients with stage III colon cancer.The median age was 58 years; 54% were male, 84% were White and 29% were >= 65 years. Eighty-three percent had stage III disease.The addition of Avastin to chemotherapy did not improve DFS. As compared to FOLFOX4 alone, the proportion of stage III patients with disease recurrence or with death due to disease progression were numerically higher for patients receiving Avastin with FOLFOX4 or with XELOX. The hazard ratios for DFS were 1.17 (95% CI: 0.98,1.39) for Avastin with FOLFOX4 versus FOLFOX4 alone and 1.07 (95% CI: 0.90, 1.28) for Avastin with XELOX versus FOLFOX4 alone. The hazard ratios for OS were 1.31 (95% CI: 1.03, 1.67) and 1.27 (95% CI: 1, 1.62) for the comparison of Avastin with FOLFOX4 versus FOLFOX4 alone and Avastin with XELOX versus FOLFOX4 alone, respectively. Similar lack of efficacy for DFS was observed in the Avastin-containing arms compared to FOLFOX4 alone in the high-risk stage II cohort.In second study [NSABP-C-08 (NCT00096278)], patients with stage II and III colon cancer who had undergone surgery with curative intent, were randomized to receive either Avastin administered at dose equivalent to 2.5 mg/kg/week with mFOLFOX6 (N=1354) or mFOLFOX6 alone (N=1356). The median age was 57 years, 50% were male and 87% White. Seventy-five percent had stage III disease. The main outcome was DFS among stage III patients. The HR for DFS was 0.92 (95% CI: 0.77, 1.10). OS was not significantly improved with the addition of Avastin to mFOLFOX6 [HR 0.96 (95% CI: 0.75,1.22)].. 14.3 First-Line Non-Squamous Non-Small Cell Lung Cancer. Study E4599The safety and efficacy of Avastin as first-line treatment of patients with locally advanced, metastatic, or recurrent non-squamous NSCLC was studied in single, large, randomized, active-controlled, open-label, multicenter study [E4599 (NCT00021060)]. total of 878 chemotherapy-naive patients with locally advanced, metastatic or recurrent non-squamous NSCLC were randomized (1:1) to receive six 21-day cycles of paclitaxel (200 mg/m2) and carboplatin (AUC 6) with or without Avastin 15 mg/kg. After completing or discontinuing chemotherapy, patients randomized to receive Avastin continued to receive Avastin 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 main outcome measure was duration of survival.The median age was 63 years; 54% were male, 43% were >= 65 years, and 28% had >= 5% weight loss at study entry. Eleven percent had recurrent disease. Of the 89% with newly diagnosed NSCLC, 12% had Stage IIIB with malignant pleural effusion and 76% had Stage IV disease.OS was statistically significantly longer for patients receiving Avastin with paclitaxel and carboplatin compared with those receiving chemotherapy alone. Median OS was 12.3 months vs. 10.3 months [HR 0.80 (95% CI: 0.68, 0.94), final p-value of 0.013, stratified log-rank test]. Based on investigator assessment which was not independently verified, patients were reported to have longer PFS with Avastin with paclitaxel and carboplatin compared to chemotherapy alone. Results are presented in Figure 3.Figure 3: Kaplan-Meier Curves for Duration of Survival in First-Line Non-Squamous Non-Small Cell Lung Cancer in Study E4599In an exploratory analysis across patient subgroups, the impact of Avastin on OS was less robust in the following subgroups: women [HR 0.99 (95% CI: 0.79, 1.25)], patients >= 65 years [HR 0.91 (95% CI: 0.72, 1.14)] and patients with >= 5% weight loss at study entry [HR 0.96 (95% CI: 0.73, 1.26)].. Figure 3. Study BO17704The safety and efficacy of Avastin in patients with locally advanced, metastatic or recurrent non-squamous NSCLC, who had not received prior chemotherapy was studied in another randomized, double-blind, placebo-controlled study [BO17704 (NCT00806923)]. total of 1043 patients were randomized (1:1:1) to receive cisplatin and gemcitabine with placebo, Avastin 7.5 mg/kg or Avastin 15 mg/kg. The main outcome measure was PFS. Secondary outcome measure was OS.The median age was 58 years; 36% were female and 29% were >= 65 years. Eight percent had recurrent disease and 77% had Stage IV disease.PFS was significantly higher in both Avastin-containing arms compared to the placebo arm [HR 0.75 (95% CI: 0.62, 0.91), p-value of 0.0026 for Avastin 7.5 mg/kg and HR 0.82 (95% CI: 0.68; 0.98), p-value of 0.0301 for Avastin 15 mg/kg]. The addition of Avastin to cisplatin and gemcitabine failed to demonstrate an improvement in the duration of OS [HR 0.93 (95% CI: 0.78; 1.11), p-value of 0.420 for Avastin 7.5 mg/kg and HR 1.03 (95% CI: 0.86, 1.23), p-value of 0.761 for Avastin 15 mg/kg]. 14.4 Recurrent Glioblastoma. Study EORTC 26101The safety and efficacy of Avastin were evaluated in multicenter, randomized (2:1), open-label study in patients with recurrent GBM (EORTC 26101, NCT01290939). Patients with first progression following radiotherapy and temozolomide were randomized (2:1) to receive Avastin (10 mg/kg every weeks) with lomustine (90 mg/m2 every weeks) or lomustine (110 mg/m2 every weeks) alone until disease progression or unacceptable toxicity. Randomization was stratified by World Health Organization performance status (0 vs. >0), steroid use (yes vs. no), largest tumor diameter (<= 40 vs. 40 mm), and institution. The main outcome measure was OS. Secondary outcome measures were investigator-assessed PFS and ORR per the modified Response Assessment in Neuro-oncology (RANO) criteria, health related quality of life (HRQoL), cognitive function, and corticosteroid use.A total of 432 patients were randomized to receive lomustine alone (N=149) or Avastin with lomustine (N=283). The median age was 57 years; 24.8% of patients were >= 65 years. The majority of patients with were male (61%); 66% had WHO performance status score 0; and in 56% the largest tumor diameter was <= 40 mm. Approximately 33% of patients randomized to receive lomustine received Avastin following documented progression.No difference in OS (HR 0.91, -value of 0.4578) was observed between arms; therefore, all secondary outcome measures are descriptive only. PFS was longer in the Avastin with lomustine arm [HR 0.52 (95% CI: 0.41, 0.64)] with median PFS of 4.2 months in the Avastin with lomustine arm and 1.5 months in the lomustine arm. Among the 50% of patients receiving corticosteroids at the time of randomization, higher percentage of patients in the Avastin with lomustine arm discontinued corticosteroids (23% vs. 12%).. Study AVF3708g and Study NCI 06-C-0064EThe efficacy and safety of Avastin 10 mg/kg every weeks in patients with previously treated GBM were evaluated in one single arm single center study (NCI 06-C-0064E) and randomized noncomparative multicenter study [AVF3708g (NCT00345163)]. Response rates in both studies were evaluated based on modified WHO criteria that considered corticosteroid use. In AVF3708g, the response rate was 25.9% (95% CI: 17%, 36.1%) with median duration of response of 4.2 months (95% CI: 3, 5.7). In Study NCI 06-C-0064E, the response rate was 19.6% (95% CI: 10.9%, 31.3%) with median duration of response of 3.9 months (95% CI: 2.4, 17.4).. 14.5 Metastatic Renal Cell Carcinoma. Study BO17705The safety and efficacy of Avastin were evaluated in patients with treatment-naive mRCC in multicenter, randomized, double-blind, international study [BO17705 (NCT00738530)] comparing interferon alfa and Avastin versus interferon alfa and placebo. total of 649 patients who had undergone nephrectomy were randomized (1:1) to receive either Avastin (10 mg/kg every weeks; = 327) or placebo (every weeks; = 322) with interferon alfa (9 MIU subcutaneously three times weekly for maximum of 52 weeks). Patients were treated until disease progression or unacceptable toxicity. The main outcome measure was investigator-assessed PFS. Secondary outcome measures were ORR and OS.The median age was 60 years (18 to 82 years); 70% were male and 96% were White. The study population was characterized by Motzer scores as follows: 28% favorable (0), 56% intermediate (1-2), 8% poor (3-5), and 7% missing.PFS was statistically significantly prolonged among patients receiving Avastin compared to placebo; median PFS was 10.2 months vs. 5.4 months [HR 0.60 (95% CI: 0.49, 0.72), p-value 0.0001, stratified log-rank test]. Among the 595 patients with measurable disease, ORR was also significantly higher (30% vs. 12%, p-value 0.0001, stratified CMH test). There was no improvement in OS based on the final analysis conducted after 444 deaths, with median OS of 23 months in the patients receiving Avastin with interferon alfa and 21 months in patients receiving interferon alone [HR 0.86, (95% CI: 0.72, 1.04)]. Results are presented in Figure 4.Figure 4: Kaplan-Meier Curves for Progression-Free Survival in Metastatic Renal Cell Carcinoma in Study BO17705. Figure 4. 14.6Persistent, Recurrent, or Metastatic Cervical Cancer. Study GOG-0240The safety and efficacy of Avastin were evaluated in patients with persistent, recurrent, or metastatic cervical cancer in randomized, four-arm, multicenter study comparing Avastin with chemotherapy versus chemotherapy alone [GOG-0240 (NCT00803062)]. total of 452 patients were randomized (1:1:1:1) to receive paclitaxel and cisplatin with or without Avastin, or paclitaxel and topotecan with or without Avastin.The dosing regimens for Avastin, paclitaxel, cisplatin and topotecan were as follows:Day 1: Paclitaxel 135 mg/m2 over 24 hours, Day 2: cisplatin 50 mg/m2 with Avastin;Day 1: Paclitaxel 175 mg/m2 over hours, Day 2: cisplatin 50 mg/m2 with Avastin;Day 1: Paclitaxel 175 mg/m2 over hours with cisplatin 50 mg/m2 with Avastin;Day 1: Paclitaxel 175 mg/m2 over hours with Avastin, Days 1-3: topotecan IV 0.75 mg/m2 over 30 minutesPatients were treated until disease progression or unacceptable adverse reactions. The main outcome measure was OS. Secondary outcome measures included ORR.The median age was 48 years (20 to 85 years). Of the 452 patients randomized at baseline, 78% of patients were White, 80% had received prior radiation, 74% had received prior chemotherapy concurrent with radiation, and 32% had platinum-free interval of less than months. Patients had GOG performance status of (58%) or (42%). Demographic and disease characteristics were balanced across arms.Results are presented in Figure and Table 13.Figure 5: Kaplan-Meier Curves for Overall Survival in Persistent, Recurrent, or Metastatic Cervical Cancer in Study GOG-0240Table 13: Efficacy Results in Study GOG-0240Efficacy ParameterAvastin with Chemotherapy(N=227)Chemotherapy(N=225)Overall Survival Median, in monthsKaplan-Meier estimates. 16.812.9 Hazard ratio (95% CI)0.74 (0.58, 0.94) p-valuelog-rank test (stratified). 0.0132The ORR was higher in patients who received Avastin with chemotherapy [45% (95% CI: 39, 52)] compared to patients who received chemotherapy alone [34% (95% CI: 28,40)].Table 14: Efficacy Results in Study GOG-0240Efficacy ParameterTopotecan and Paclitaxel with or without Avastin(N=223)Cisplatin and Paclitaxelwith or without Avastin(N=229)Overall Survival Median, in monthsKaplan-Meier estimates. 13.315.5 Hazard ratio (95% CI)1.15 (0.91, 1.46) p-value0.23The HR for OS with Avastin with cisplatin and paclitaxel as compared to cisplatin and paclitaxel alone was 0.72 (95% CI: 0.51,1.02).

Figure 5. 14.7Stage III or IV Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer Following Initial Surgical Resection. Study GOG-0218The safety and efficacy of Avastin were evaluated in multicenter, randomized, double-blind, placebo controlled, three arm study [Study GOG-0218 (NCT00262847)] evaluating the effect of adding Avastin to carboplatin and paclitaxel for the treatment of patients with stage III or IV epithelial ovarian, fallopian tube or primary peritoneal cancer (N=1873) following initial surgical resection. Patients were randomized (1:1:1) to one of the following arms:CPP: carboplatin (AUC 6) and paclitaxel (175 mg/m2) for six cycles, with concurrent placebo started at cycle 2, followed by placebo alone every three weeks for total of up to 22 cycles of therapy (n=625) orCPB15: carboplatin (AUC 6) and paclitaxel (175 mg/m2) for six cycles, with concurrent Avastin started at cycle 2, followed by placebo alone every three weeks for total of up to 22 cycles of therapy (n=625) orCPB15+: carboplatin (AUC 6) and paclitaxel (175 mg/m2) for six cycles, with concurrent Avastin started at cycle 2, followed by Avastin as single agent every three weeks for total of up to 22 cycles of therapy (n=623).The main outcome measure was investigator-assessed PFS. OS was secondary outcome measure.The median age was 60 years (range 22-89 years) and 28% of patients were >65 years of age.Overall, approximately 50% of patients had GOG PS of at baseline, and 43% GOG PS score of 1. Patients had either epithelial ovarian cancer (83%), primary peritoneal cancer (15%), or fallopian tube cancer (2%). Serous adenocarcinoma was the most common histologic type (85% in CPP and CPB15 arms, 86% in CPB15+ arm). Overall, approximately 34% of patients had resected FIGO Stage III with residual disease 1 cm, 40% had resected Stage III with residual disease >1 cm, and 26% had resected Stage IV disease.The majority of patients in all three treatment arms received subsequent antineoplastic treatment, 78.1% in the CPP arm, 78.6% in the CPB15 arm, and 73.2% in the CPB15+ arm. higher proportion of patients in the CPP arm (25.3%) and CPB15 arm (26.6%) received at least one anti-angiogenic (including bevacizumab) treatment after discontinuing from study compared with the CPB15+ arm (15.6%).Study results are presented in Table 15 and Figure 6.Table 15: Efficacy Results in Study GOG-0218Efficacy ParameterAvastin with carboplatin and paclitaxel followed by Avastin alone(N=623)Avastin with carboplatin and paclitaxel(N=625)Carboplatin and paclitaxel(N= 625)NS=not significantProgression-Free Survival per Investigator Median, in months18.212.812.0 Hazard ratio (95% CI)Relative to the control arm; stratified hazard ratio 0.62 (0.52, 0.75)0.83 (0.70, 0.98) -valueTwo-sided p-value based on re-randomization test 0.0001NSOverall SurvivalFinal overall survival analysis Median, in months43.838.840.6 Hazard ratio (95% CI) 0.89 (0.76, 1.05)1.06 (0.90, 1.24)Figure 6: Kaplan-Meier Curves for Investigator-Assessed Progression-Free Survival in Stage III or IV Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer Following Initial Surgical Resection in Study GOG-0218.

Figure 6. 14.8Platinum-Resistant Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer. Study MO22224The safety and efficacy of Avastin were evaluated in multicenter, open-label, randomized study [MO22224 (NCT00976911)] comparing Avastin with chemotherapy versus chemotherapy alone in patients with platinum-resistant, recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer that recurred within <6 months from the most recent platinum-based therapy (N=361). Patients had received no more than prior chemotherapy regimens. Patients received one of the following chemotherapy regimens at the discretion of the investigator: paclitaxel (80 mg/m2 on days 1, 8, 15 and 22 every weeks; pegylated liposomal doxorubicin 40 mg/m2 on day every weeks; or topotecan mg/m2 on days 1, and 15 every weeks or 1.25 mg/m2 on days 1-5 every weeks). Patients were treated until disease progression, unacceptable toxicity, or withdrawal. Forty percent of patients on the chemotherapy alone arm received Avastin alone upon progression. The main outcome measure was investigator-assessed PFS. Secondary outcome measures were ORR and OS.The median age was 61 years (25 to 84 years) and 37% of patients were >=65 years. Seventy-nine percent had measurable disease at baseline, 87% had baseline CA-125 levels >=2 times ULN and 31% had ascites at baseline. Seventy-three percent had platinum-free interval (PFI) of months to months and 27% had PFI of <3 months. ECOG performance status was for 59%, for 34% and for 7% of the patients.The addition of Avastin to chemotherapy demonstrated statistically significant improvement in investigator-assessed PFS, which was supported by retrospective independent review analysis.

Figure 7. 14.9Platinum-Sensitive Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer. Study AVF4095gThe safety and efficacy of Avastin were evaluated in randomized, double-blind, placebo-controlled study [AVF4095g (NCT00434642)] studying Avastin with chemotherapy versus chemotherapy alone in the treatment of patients with platinum-sensitive recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who have not received prior chemotherapy in the recurrent setting or prior bevacizumab treatment (N=484). Patients were randomized (1:1) to receive Avastin (15 mg/kg day 1) or placebo every weeks with carboplatin (AUC 4, day 1) and gemcitabine (1000 mg/m2 on days and 8) for to 10 cycles followed by Avastin or placebo alone until disease progression or unacceptable toxicity. The main outcome measures were investigator-assessed PFS. Secondary outcome measures were ORR and OS.The median age was 61 years (28 to 87 years) and 37% of patients were >=65 years. All patients had measurable disease at baseline, 74% had baseline CA-125 levels >ULN (35 U/mL). The platinum-free interval (PFI) was months to 12 months in 42 of patients and >12 months in 58% of patients. The ECOG performance status was or for 99.8% of patients.A statistically significant prolongation in PFS was demonstrated among patients receiving Avastin with chemotherapy compared to those receiving placebo with chemotherapy (Table 18 and Figure 8). Independent radiology review of PFS was consistent with investigator assessment [HR 0.45 (95% CI: 0.35, 0.58)]. OS was not significantly improved with the addition of Avastin to chemotherapy [HR 0.95 (95% CI: 0.77, 1.17)].Table 18: Efficacy Results in Study AVF4095gEfficacy ParameterAvastin with Gemcitabine and Carboplatin(N=242)Placebo with Gemcitabine and Carboplatin(N=242)Progression-Free Survival Median, in months12.48.4 Hazard ratio (95% CI)0.46(0.37, 0.58)p-value< 0.0001Overall Response Rate patients with overall response78%57% p-value< 0.0001Figure 8: Kaplan-Meier Curves for Progression-Free Survival in Platinum-Sensitive Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer in Study AVF4095g.

Study GOG-0213The safety and efficacy of Avastin were evaluated in randomized, controlled, open-label study [Study GOG-0213 (NCT00565851)] of Avastin with chemotherapy versus chemotherapy alone in the treatment of patients with platinum-sensitive recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have not received more than one previous regimen of chemotherapy (N=673). Patients were randomized (1:1) to receive carboplatin (AUC 5) and paclitaxel (175 mg/m2 IV over hours) every weeks for to cycles (N=336) or Avastin (15 mg/kg) every weeks with carboplatin (AUC 5) and paclitaxel (175 mg/m2 IV over hours) for to cycles followed by Avastin (15 mg/kg every weeks) as single agent until disease progression or unacceptable toxicity. The main outcome measure was OS. Other outcome measures were investigator-assessed PFS, and ORR.The median age was 60 years (23 to 85 years) and 33% of patients were >= 65 years. Eighty-three percent had measurable disease at baseline and 74% had abnormal CA-125 levels at baseline. Ten percent of patients had received prior bevacizumab. Twenty-six percent had PFI of months to 12 months and 74% had PFI of >12 months. GOG performance status was or for 99% of patients.Results are presented in Table 19 and Figure 9.Table 19: Efficacy Results in Study GOG-0213Efficacy ParameterAvastin with Carboplatin and Paclitaxel(N=337)Carboplatin and Paclitaxel(N=336)Overall Survival Median, in months42.637.3 Hazard ratio (95% CI) (IVRS)HR was estimated from Cox proportional hazards models stratified by the duration of treatment free-interval prior to enrolling onto this study per IVRS (interactive voice response system) and secondary surgical debulking status. 0.84 (0.69, 1.01) Hazard ratio (95% CI) (eCRF)HR was estimated from Cox proportional hazards models stratified by the duration of platinum free-interval prior to enrolling onto this study per eCRF (electronic case report form) and secondary surgical debulking status. 0.82 (0.68, 0.996)Progression-Free Survival Median, in months13.810.4 Hazard ratio (95% CI) (IVRS) 0.61 (0.51, 0.72)Overall Response Rate Number of patients with measurable disease at baseline274286 Rate, %213 (78%)159 (56%)Figure 9: Kaplan Meier Curves for Overall Survival in Platinum-Sensitive Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer in Study GOG-0213. Figure 9. 14.10 Hepatocellular Carcinoma. The efficacy of Avastin in combination with atezolizumab was investigated in IMbrave150 (NCT03434379), multicenter, international, open-label, randomized trial in patients with locally advanced unresectable and/or metastatic hepatocellular carcinoma who have not received prior systemic therapy. Randomization was stratified by geographic region (Asia excluding Japan vs. rest of world), macrovascular invasion and/or extrahepatic spread (presence vs. absence), baseline AFP (<400 vs. >=400 ng/mL), and by ECOG performance status (0 vs. 1).A total of 501 patients were randomized (2:1) to receive either atezolizumab as an intravenous infusion of 1200 mg, followed by 15 mg/kg Avastin, on the same day every weeks or sorafenib 400 mg given orally twice daily, until disease progression or unacceptable toxicity. Patients could discontinue either atezolizumab or Avastin (e.g., due to adverse events) and continue on single-agent therapy until disease progression or unacceptable toxicity associated with the single-agent.The study enrolled patients who were ECOG performance score or and who had not received prior systemic treatment. Patients were required to be evaluated for the presence of varices within months prior to treatment, and were excluded if they had variceal bleeding within months prior to treatment, untreated or incompletely treated varices with bleeding, or high risk of bleeding. Patients with Child-Pugh or cirrhosis, moderate or severe ascites; history of hepatic encephalopathy; history of autoimmune disease; administration of live, attenuated vaccine within weeks prior to randomization; administration of systemic immunostimulatory agents within weeks or systemic immunosuppressive medications within weeks prior to randomization; or untreated or corticosteroid-dependent brain metastases were excluded. Tumor assessments were performed every weeks for the first 54 weeks and every weeks thereafter.The demographics and baseline disease characteristics of the study population were balanced between the treatment arms. The median age was 65 years (range: 26 to 88) and 83% of patients were male. The majority of patients were Asian (57%) or White (35%); 40% were from Asia (excluding Japan). Approximately 75% of patients presented with macrovascular invasion and/or extrahepatic spread and 37% had baseline AFP >=400 ng/mL. Baseline ECOG performance status was (62%) or (38%). HCC risk factors were Hepatitis in 48% of patients, Hepatitis in 22% and 31% of patients had non-viral liver disease. The majority of patients had BCLC stage (82%) disease at baseline, while 16% had stage and 3% had stage A.The major efficacy outcome measures were overall survival (OS) and independent review facility (IRF)-assessed progression free survival (PFS) per RECIST v1.1. Additional efficacy outcome measures were IRF-assessed overall response rate (ORR) per RECIST and mRECIST.Efficacy results are presented in Table 20 and Figure 10.Table 20: Efficacy Results from IMbrave150Avastin in combination with Atezolizumab(N= 336)Sorafenib(N=165)CI=confidence interval; HCC mRECIST= Modified RECIST Assessment for Hepatocellular Carcinoma; NE=not estimable; N/A=not applicable; RECIST 1.1= Response Evaluation Criteria in Solid Tumors v1.1Overall SurvivalNumber of deaths (%)96 (29)65 (39)Median OS in months(95% CI)NE(NE, NE)13.2(10.4, NE)Hazard ratioStratified by geographic region (Asia excluding Japan vs. rest of world), macrovascular invasion and/or extrahepatic spread (presence vs. absence), and baseline AFP (<400 vs. >=400 ng/mL) (95% CI)0.58 (0.42, 0.79)p-valueBased on two-sided stratified log-rank test; as compared to significance level 0.004 (2-sided) based on 161/312=52% information using the OBF method 0.0006 Progression-Free SurvivalPer independent radiology review Number of events(%)197 (59)109 (66)Median PFS in months (95% CI)6.8 (5.8, 8.3)4.3 (4.0, 5.6)Hazard ratio (95% CI)0.59 (0.47, 0.76)p-value<0.0001Overall Response Rate Confirmed responses (ORR), RECIST 1.1Number of responders (%)93 (28)19 (12)(95% CI)(23, 33)(7,17)p-valueBased on two-sided Cochran-Mantel-Haesnszel test <0.0001Complete responses, (%)22 (7)0Partial responses, (%)71 (21)19 (12)Duration of Response (DOR) RECIST 1.1(n=93)(n=19)Median DOR in months(95% CI)NE(NE, NE)6.3(4.7, NE)Range (months)(1.3Denotes censored value, 13.4)(1.4, 9.1)Overall Response Rate (ORR), HCC mRECIST Number of responders (%)112 (33)21 (13)(95% CI)(28, 39)(8, 19)p-value <0.0001Complete responses, (%)37 (11)3 (1.8)Partial responses, (%)75 (22)18 (11)Duration of Response (DOR) HCC mRECIST (n=112)(n=21)Median DOR in months(95% CI)NE(NE, NE)6.3(4.9, NE)Range (months)(1.3, 13.4)(1.4, 9.1)Figure 10: Kaplan-Meier Plot of Overall Survival in IMbrave150.

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.The safety data in Warnings and Precautions and described below reflect exposure to Avastin 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 HCC (IMbrave150) at the recommended dose and schedule for median of to 23 doses. The most common adverse reactions observed in patients receiving Avastin as single agent or in combination with other anti-cancer therapies at rate 10% were epistaxis, headache, hypertension, rhinitis, proteinuria, taste alteration, dry skin, hemorrhage, lacrimation disorder, back pain, and exfoliative dermatitis.Across clinical studies, Avastin was discontinued in 8% to 22% of patients because of adverse reactions [see Clinical Studies (14)]. Metastatic Colorectal Cancer In Combination with bolus-IFLThe safety of Avastin was evaluated in 392 patients who received at least one dose of Avastin in double-blind, active-controlled study (AVF2107g), which compared Avastin (5 mg/kg every 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, Avastin with bolus-IFL, or Avastin 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 Avastin vs. Placebo in Study AVF2107gAdverse ReactionNCI-CTC version Avastin with IFL (N=392)Placebo with IFL(N=396)Hematology Leukopenia37%31% Neutropenia21%14%Gastrointestinal Diarrhea34%25% Abdominal pain8%5% Constipation4%2%Vascular Hypertension12%2% Deep vein thrombosis9%5% Intra-abdominal thrombosis3%1% Syncope3%1%General Asthenia10%7% Pain8%5%. In Combination with FOLFOX4The safety of Avastin 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, Avastin (10 mg/kg every weeks prior to FOLFOX4 on Day 1) with FOLFOX4, or Avastin alone (10 mg/kg every weeks). Avastin 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 4-5 hematologic occurring at higher incidence (>= 2%) in patients receiving Avastin 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 CancerThe safety of Avastin was evaluated as first-line treatment in 422 patients with unresectable NSCLC who received at least one dose of Avastin in an active-controlled, open-label, multicenter trial (E4599) [see Clinical Studies (14.3)]. Chemotherapy naive 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 Avastin (15 mg/kg every weeks). After completion or upon discontinuation of chemotherapy, patients randomized to receive Avastin continued to receive Avastin 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 higher incidence (>= 2%) in patients receiving Avastin 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 or neutropenia (4% vs. 2%), hyponatremia (4% vs. 1%), headache (3% vs. 1%) and proteinuria (3% vs. 0%).. Recurrent GlioblastomaThe safety of Avastin was evaluated in 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 Avastin and are considered safety evaluable [see Clinical Studies (14.4)]. Patients were randomized (2:1) to receive Avastin (10 mg/kg every 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 Avastin with lomustine arm, 22% of patients discontinued treatment due to adverse reactions compared with 10% of patients in the lomustine arm. In patients receiving Avastin with lomustine, the adverse reaction profile was similar to that observed in other approved indications.. Metastatic Renal Cell CarcinomaThe safety of Avastin was evaluated in 337 patients who received at least one dose of Avastin in multicenter, double-blind study (BO17705) in patients with mRCC. Patients who had undergone nephrectomy were randomized (1:1) to receive either Avastin (10 mg/kg every 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 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).

Persistent, Recurrent, or Metastatic Cervical CancerThe safety of Avastin was evaluated in 218 patients who received at least one dose of Avastin in 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 Avastin (15 mg/kg every weeks), or paclitaxel and topotecan with or without Avastin (15 mg/kg every weeks). The demographics of the safety population were similar to the demographics of the efficacy population.Grades 3-4 adverse reactions occurring at higher incidence (>= 2%) in 218 patients receiving Avastin 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%).

Epithelial Ovarian, Fallopian Tube or Primary Peritoneal Cancer Stage III or IV Following Initial Surgical ResectionThe safety of Avastin was evaluated in GOG-0218, multicenter, randomized, double-blind, placebo controlled, three arm study, which evaluated the addition of Avastin to carboplatin and paclitaxel for the treatment of patients with stage III or IV epithelial ovarian, fallopian tube or primary peritoneal cancer following initial surgical resection [see Clinical Studies (14.7)]. Patients were randomized (1:1:1) to carboplatin and paclitaxel without Avastin (CPP), carboplatin and paclitaxel with Avastin for up to six cycles (CPB15), or carboplatin and paclitaxel with Avastin for six cycles followed by Avastin as single agent for up to 16 additional doses (CPB15+). Avastin was given at 15 mg/kg every three weeks. On this trial, 1215 patients received at least one dose of Avastin. The demographics of the safety population were similar to the demographics of the efficacy population.Grades 3-4 adverse reactions occurring at higher incidence (>=2%) in either of the Avastin arms versus the control arm were fatigue (CPB15+ 9%, CPB15 6%, CPP 6%), hypertension (CPB15+ 10%, CPB15 6%, CPP 2%), thrombocytopenia (CPB15+ 21%, CPB15 20%, CPP 15%) and leukopenia (CPB15+ 51%, CPB15 53%, CPP 50%).

Platinum-Resistant Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal CancerThe safety of Avastin was evaluated in 179 patients who received at least one dose of Avastin in multicenter, open-label study (MO22224) in which patients were randomized (1:1) to Avastin with chemotherapy or chemotherapy alone in patients with platinum resistant, recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer that recurred within 6 months from the most recent platinum based therapy [see Clinical Studies (14.8)]. Patients were randomized to receive Avastin 10 mg/kg every weeks or 15 mg/kg every weeks. Patients had received no more than 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.

Hepatocellular Carcinoma (HCC) The safety of Avastin in combination with atezolizumab was evaluated in IMbrave150, multicenter, international, randomized, open-label trial in patients with locally advanced or metastatic or unresectable hepatocellular carcinoma who have not received prior systemic treatment [see Clinical Studies (14.10)]. Patients received 1,200 mg of atezolizumab intravenously followed by 15 mg/kg Avastin (n=329) every weeks, or 400 mg of sorafenib (n=156) given orally twice daily, until disease progression or unacceptable toxicity. The median duration of exposure to Avastin was 6.9 months (range: 0-16 months) and to atezolizumab was 7.4 months (range: 0-16 months).Fatal adverse reactions occurred in 4.6% of patients in the Avastin and atezolizumab arm. The most common adverse reactions leading to death were gastrointestinal and esophageal varices hemorrhage (1.2%) and infections (1.2%).Serious adverse reactions occurred in 38% of patients in the Avastin and atezolizumab arm. The most frequent serious adverse reactions (>= 2%) were gastrointestinal hemorrhage (7%), infections (6%), and pyrexia (2.1%).Adverse reactions leading to discontinuation of Avastin occurred in 15% of patients in the Avastin and atezolizumab arm. The most common adverse reactions leading to Avastin discontinuation were hemorrhages (4.9%), including bleeding varicose vein, hemorrhage and gastrointestinal, subarachnoid, and pulmonary hemorrhages; and increased transaminases or bilirubin (0.9%).Adverse reactions leading to interruption of Avastin occurred in 46% of patients in the Avastin and atezolizumab arm; the most common (>= 2%) were proteinuria (6%); infections (6%); hypertension (6%); liver function laboratory abnormalities including increased transaminases, bilirubin, or alkaline phosphatase (4.6%); gastrointestinal hemorrhages (3%); thrombocytopenia/decreased platelet count (4.3%); and pyrexia (2.4%).Tables and 10 summarize adverse reactions and laboratory abnormalities, respectively, in patients who received Avastin and atezolizumab in IMbrave150.Table 9: Adverse Reactions Occurring in >=10% of Patients with HCC Receiving Avastin in IMbrave150Adverse ReactionAvastin in combination with atezolizumab(n 329)Sorafenib (n=156)All GradesIncludes fatigue and asthenia (%)Grades 3-4 (%)All Grades (%)Grades 3-4 (%)2 Graded per NCI CTCAE v4.0Vascular DisordersHypertension30152412General Disorders and Administration Site ConditionsFatigue/asthenia 262326Pyrexia180100Renal and Urinary Disorders Proteinuria20370.6InvestigationsWeight Decreased110100Skin and Subcutaneous Tissue Disorders Pruritus190100Rash120172.6Gastrointestinal DisordersDiarrhea191.8495Constipation130140Abdominal Pain120170Nausea120160Vomiting10080Metabolism and Nutrition DisordersDecreased Appetite181.2243.8Respiratory, Thoracic and Mediastinal DisordersCough120100Epistaxis1004.50Injury, Poisoning and Procedural ComplicationsInfusion Related Reaction112.400Table 10: Laboratory Abnormalities Worsening from Baseline Occurring in >=20% of Patients with HCC Receiving Avastin in IMbrave150Laboratory AbnormalityAvastin in combination with atezolizumab(n=329)Sorafenib (n=156)All GradesGraded per NCI CTCAE v4.0 (%)Grades 3-4 (%)All Grades (%)Grades 3-4 (%)Each test incidence is based on the number of patients who had both baseline and at least one on-study laboratory measurement available: Avastin plus atezolizumab (222-323) and sorafenib (90-153) NA Not applicable.ChemistryIncreased AST86169016Increased Alkaline Phosphatase704764.6Increased ALT628704.6Decreased Albumin601.5540.7Decreased Sodium5413499Increased Glucose489434.6Decreased Calcium300.3351.3Decreased Phosphorus264.75816Increased Potassium231.9162Hypomagnesemia220220HematologyDecreased Platelet687634.6Decreased Lymphocytes62135811Decreased Hemoglobin583.1623.9Increased Bilirubin5785914Decreased Leukocyte323.4291.3Decreased Neutrophil232.3161.1. 6.2Immunogenicity. As with all therapeutic proteins, there is 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 to bevacizumab 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 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 Avastin. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.General: PolyserositisCardiovascular: Pulmonary hypertension, Mesenteric venous occlusionGastrointestinal: Gastrointestinal ulcer, Intestinal necrosis, Anastomotic ulcerationHemic and lymphatic: PancytopeniaHepatobiliary disorders: Gallbladder perforationMusculoskeletal and Connective Tissue Disorders: Osteonecrosis of the jawRenal: Renal thrombotic microangiopathy (manifested as severe proteinuria)Respiratory: Nasal septum perforationVascular: Arterial (including aortic) aneurysms, dissections, and rupture.

ANIMAL PHARMACOLOGY & OR TOXICOLOGY SECTION.

13.2 Animal Toxicology and/or Pharmacology. Rabbits dosed with bevacizumab exhibited reduced wound healing capacity. Using full-thickness skin incision and partial thickness circular dermal wound models, bevacizumab dosing resulted in reductions in wound tensile strength, decreased granulation and re-epithelialization, and delayed time to wound closure.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. No studies have been conducted to assess potential of bevacizumab for carcinogenicity or mutagenicity.Bevacizumab may impair fertility. Female cynomolgus monkeys treated with 0.4 to 20 times the recommended human dose of bevacizumab exhibited arrested follicular development or absent corpora lutea, as well as dose-related decreases in ovarian and uterine weights, endometrial proliferation, and the number of menstrual cycles. Following 4- or 12-week recovery period, there was trend suggestive of reversibility. After the 12-week recovery period, follicular maturation arrest was no longer observed, but ovarian weights were still moderately decreased. Reduced endometrial proliferation was no longer observed at the 12-week recovery time point; however, decreased uterine weight, absent corpora lutea, and reduced number of menstrual cycles remained evident.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Bevacizumab 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 bevacizumab to xenotransplant models of colon cancer in nude (athymic) mice caused reduction of microvascular growth and inhibition of metastatic disease progression.. 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 population pharmacokinetic analysis of 491 patients who received to 20 mg/kg of Avastin every week, every weeks, or every 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 dose of 10 mg/kg once every weeks is 2.8.Population simulations of bevacizumab exposures provide median trough concentration of 80.3 mcg/mL on Day 84 (10th, 90th percentile: 45, 128) following dose of mg/kg once every two weeks.. DistributionThe 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 PopulationsThe clearance of bevacizumab varied by body weight, sex, and tumor burden. After correcting for body weight, males had higher bevacizumab clearance (0.26 L/day vs. 0.21 L/day) and larger central volume of distribution (3.2 vs. 2.7 L) than females. Patients with higher tumor burden (at or above median value of tumor surface area) had 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 Avastin as compared to females and patients with low tumor burden.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. Effects of Avastin on Other DrugsNo clinically meaningful effect on the pharmacokinetics of irinotecan or its active metabolite SN38, interferon alfa, carboplatin or paclitaxel was observed when Avastin was administered in combination with these drugs; however, of the patients receiving Avastin 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 greater paclitaxel exposure at Day 63 than at Day 0.

FEMALES & MALES OF REPRODUCTIVE POTENTIAL SECTION.

8.3 Females and Males of Reproductive Potential. Contraception. FemalesAvastin may cause fetal harm when administered to pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment with Avastin and for months after the last dose.. Infertility FemalesAvastin increases 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 Avastin. Long-term effects of Avastin on fertility are not known.In clinical study of 179 premenopausal women randomized to receive chemotherapy with or without Avastin, the incidence of ovarian failure was higher in patients who received Avastin with chemotherapy (34%) compared to patients who received chemotherapy alone (2%). After discontinuing Avastin with chemotherapy, recovery of ovarian function occurred in 22% of these patients [see Warnings and Precautions (5.11), Adverse Reactions (6.1)].

GERIATRIC USE SECTION.

8.5 Geriatric Use. In an exploratory pooled analysis of 1745 patients from five randomized, controlled studies, 35% of patients were >= 65 years old. The overall incidence of ATE was increased in all patients receiving Avastin with chemotherapy as compared to those receiving chemotherapy alone, regardless of age; however, the increase in the incidence of ATE was greater in patients >= 65 years (8% vs. 3%) as compared to patients 65 years (2% vs. 1%) [see Warnings and Precautions (5.4)].

HOW SUPPLIED SECTION.

16 HOW SUPPLIED/STORAGE AND HANDLING. Avastin (bevacizumab) injection is clear to slightly opalescent, colorless to pale brown, sterile solution for intravenous infusion supplied as single-dose vials in the following strengths:100 mg/4 mL: carton of one vial (NDC 50242-060-01); carton of 10 vials (NDC 50242-060-10).400 mg/16 mL: carton of one vial (NDC 50242-061-01); carton of 10 vials (NDC 50242-061-10).. 100 mg/4 mL: carton of one vial (NDC 50242-060-01); carton of 10 vials (NDC 50242-060-10).. 400 mg/16 mL: carton of one vial (NDC 50242-061-01); carton of 10 vials (NDC 50242-061-10).. Store refrigerated at 2C to 8C (36F to 46F) in the original carton until time of use to protect from light. Do not freeze or shake the vial or carton.

IMMUNOGENICITY.

6.2Immunogenicity. As with all therapeutic proteins, there is 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 to bevacizumab 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 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.

INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION. Gastrointestinal Perforations and Fistulae: Avastin may increase the risk of developing gastrointestinal perforations and fistulae. Advise patients to immediately contact their health care provider for high fever, rigors, persistent or severe abdominal pain, severe constipation, or vomiting [see Warnings and Precautions (5.1)].. Surgery and Wound Healing Complications: Avastin can increase the risk of wound healing complications. Instruct patients not to undergo surgery without first discussing this potential risk with their healthcare provider [see Warnings and Precautions (5.2)].. Hemorrhage: Avastin can increase the risk of hemorrhage. Advise patients to immediately contact their health care provider for signs and symptoms of serious or unusual bleeding including coughing or spitting blood [see Warnings and Precautions (5.3)].. Arterial and Venous Thromboembolic Events: Avastin increases the risk of arterial and venous thromboembolic events. Advise patients to immediately contact their health care provider for signs and symptoms of arterial or venous thromboembolism [see Warnings and Precautions (5.4, 5.5)].. Hypertension: Avastin can increase blood pressure. Advise patients that they will undergo routine blood pressure monitoring and to contact their healthcare provider if they experience changes in blood pressure [see Warnings and Precautions (5.6)].. Posterior Reversible Leukoencephalopathy Syndrome: Posterior reversible encephalopathy syndrome (PRES) has been associated with Avastin treatment. Advise patients to immediately contact their health care provider for new onset or worsening neurological function [see Warnings and Precautions (5.7)].. Renal Injury and Proteinuria: Avastin increases the risk of proteinuria and renal injury, including nephrotic syndrome. Advise patients that treatment with Avastin requires regular monitoring of renal function and to contact their health care provider for proteinuria or signs and symptoms of nephrotic syndrome [see Warnings and Precautions (5.8)].. Infusion-Related Reactions: Avastin can cause infusion-related reactions. Advise patients to contact their healthcare provider immediately for signs or symptoms of infusion-related reactions [see Warnings and Precautions (5.9)]..

Ovarian Failure: Avastin may lead to ovarian failure. Advise patients of potential options for preservation of ova prior to starting treatment [see Warnings and Precautions (5.11)].. Lactation: Advise women not to breastfeed during treatment with Avastin and for months after the last dose [see Use in Specific Populations (8.2)].

LACTATION SECTION.

8.2 Lactation. Risk SummaryNo data are available regarding the presence of bevacizumab 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 Avastin and for months after the last dose.

MECHANISM OF ACTION SECTION.

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

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. No studies have been conducted to assess potential of bevacizumab for carcinogenicity or mutagenicity.Bevacizumab may impair fertility. Female cynomolgus monkeys treated with 0.4 to 20 times the recommended human dose of bevacizumab exhibited arrested follicular development or absent corpora lutea, as well as dose-related decreases in ovarian and uterine weights, endometrial proliferation, and the number of menstrual cycles. Following 4- or 12-week recovery period, there was trend suggestive of reversibility. After the 12-week recovery period, follicular maturation arrest was no longer observed, but ovarian weights were still moderately decreased. Reduced endometrial proliferation was no longer observed at the 12-week recovery time point; however, decreased uterine weight, absent corpora lutea, and reduced number of menstrual cycles remained evident.. 13.2 Animal Toxicology and/or Pharmacology. Rabbits dosed with bevacizumab exhibited reduced wound healing capacity. Using full-thickness skin incision and partial thickness circular dermal wound models, bevacizumab dosing resulted in reductions in wound tensile strength, decreased granulation and re-epithelialization, and delayed time to wound closure.

PEDIATRIC USE SECTION.

8.4 Pediatric Use. The safety and effectiveness of Avastin 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 Avastin. Avastin is not approved for use in patients under the age of 18 years.Antitumor activity was not observed among eight pediatric patients with relapsed GBM who received bevacizumab and irinotecan. Addition of Avastin to standard of care did not result in improved event-free survival in pediatric patients enrolled in two randomized clinical studies, one in high grade glioma (n= 121) and one in metastatic rhabdomyosarcoma or non-rhabdomyosarcoma soft tissue sarcoma (n= 154).Based on the population pharmacokinetics analysis of data from 152 pediatric and young adult patients with cancer (7 months to 21 years of age), bevacizumab clearance normalized by body weight in pediatrics was comparable to that in adults.. Juvenile Animal Toxicity DataJuvenile cynomolgus monkeys with open growth plates exhibited physeal dysplasia following 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.

PHARMACOKINETICS SECTION.

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 population pharmacokinetic analysis of 491 patients who received to 20 mg/kg of Avastin every week, every weeks, or every 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 dose of 10 mg/kg once every weeks is 2.8.Population simulations of bevacizumab exposures provide median trough concentration of 80.3 mcg/mL on Day 84 (10th, 90th percentile: 45, 128) following dose of mg/kg once every two weeks.. DistributionThe 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 PopulationsThe clearance of bevacizumab varied by body weight, sex, and tumor burden. After correcting for body weight, males had higher bevacizumab clearance (0.26 L/day vs. 0.21 L/day) and larger central volume of distribution (3.2 vs. 2.7 L) than females. Patients with higher tumor burden (at or above median value of tumor surface area) had 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 Avastin as compared to females and patients with low tumor burden.

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryBased on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)], Avastin may cause fetal harm in pregnant women. Limited postmarketing reports describe cases of fetal malformations with use of Avastin in pregnancy; however, these reports are insufficient to determine drug-associated risks. In animal reproduction studies, intravenous administration of bevacizumab to pregnant rabbits every days during organogenesis at doses approximately 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, embryofetal development, and postnatal development. Advise pregnant women of the potential risk to 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 DataPregnant rabbits dosed with 10 mg/kg to 100 mg/kg bevacizumab (approximately 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 mg/kg dose, 76% for the 30 mg/kg dose, and 95% for the 100 mg/kg dose) or fetal alterations (9% for the 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.

Risk SummaryNo data are available regarding the presence of bevacizumab 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 Avastin and for months after the last dose.. 8.3 Females and Males of Reproductive Potential. Contraception. FemalesAvastin may cause fetal harm when administered to pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment with Avastin and for months after the last dose.. Infertility FemalesAvastin increases 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 Avastin. Long-term effects of Avastin on fertility are not known.In clinical study of 179 premenopausal women randomized to receive chemotherapy with or without Avastin, the incidence of ovarian failure was higher in patients who received Avastin with chemotherapy (34%) compared to patients who received chemotherapy alone (2%). After discontinuing Avastin 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 Avastin 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 Avastin. Avastin is not approved for use in patients under the age of 18 years.Antitumor activity was not observed among eight pediatric patients with relapsed GBM who received bevacizumab and irinotecan.

The incidence and severity of physeal dysplasia were dose-related and were partially reversible upon cessation of treatment.. 8.5 Geriatric Use. In an exploratory pooled analysis of 1745 patients from five randomized, controlled studies, 35% of patients were >= 65 years old. The overall incidence of ATE was increased in all patients receiving Avastin with chemotherapy as compared to those receiving chemotherapy alone, regardless of age; however, the increase in the incidence of ATE was greater in patients >= 65 years (8% vs. 3%) as compared to patients 65 years (2% vs. 1%) [see Warnings and Precautions (5.4)].

Congestive Heart Failure (CHF): Discontinue Avastin in patients who develop CHF. (5.12). 5.1 Gastrointestinal Perforations and Fistulae. Serious, and sometimes fatal, gastrointestinal perforation occurred at higher incidence in patients receiving Avastin compared to patients receiving chemotherapy. The incidence ranged from 0.3% to 3% across clinical studies, with the highest incidence in patients with 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 higher incidence in patients receiving Avastin 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 months of the first dose. Patients who develop gastrointestinal vaginal fistula may also have bowel obstruction and require surgical intervention, as well as diverting ostomy.Avoid Avastin 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 fistula. Discontinue in patients with fistula formation involving any internal organ. 5.2 Surgery and Wound Healing Complications. In controlled clinical study in which Avastin 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 Avastin and 4% in patients who did not receive Avastin. In controlled clinical study in patients with relapsed or recurrent GBM, the incidence of wound healing events was 5% in patients who received Avastin and 0.7% in patients who did not receive Avastin [see Adverse Reactions (6.1)]. In patients who experience wound healing complications during Avastin treatment, withhold Avastin until adequate wound healing. Withhold for at least 28 days prior to elective surgery. Do not administer for at least 28 days following major surgery and until adequate wound healing. The safety of resumption of AVASTIN after resolution of wound healing complications has not been established [see Dosage and Administration (2.9)].Necrotizing fasciitis including fatal cases, has been reported in patients receiving Avastin, usually secondary to wound healing complications, gastrointestinal perforation or fistula formation. Discontinue Avastin in patients who develop necrotizing fasciitis. 5.3 Hemorrhage. Avastin can result in two distinct patterns of bleeding: minor hemorrhage, which is most commonly Grade epistaxis, and serious hemorrhage, which in some cases has been fatal. Severe or fatal hemorrhage, including hemoptysis, gastrointestinal bleeding, hematemesis, CNS hemorrhage, epistaxis, and vaginal bleeding, occurred up to 5-fold more frequently in patients receiving Avastin compared to patients receiving chemotherapy alone. Across clinical studies, the incidence of Grades 3-5 hemorrhagic events ranged from 0.4% to 7% in patients receiving Avastin [see Adverse Reactions (6.1)]. Serious or fatal pulmonary hemorrhage occurred in 31% of patients with squamous NSCLC and 4% of patients with non-squamous NSCLC receiving Avastin with chemotherapy compared to none of the patients receiving chemotherapy alone.An evaluation for the presence of varices is recommended within months of initiation of Avastin in patients with HCC. There is lack of clinical data to support the safety of Avastin in patients with variceal bleeding within months prior to treatment, untreated or incompletely treated varices with bleeding, or high risk of bleeding because these patients were excluded from clinical trials of Avastin in HCC [see Clinical Studies (14.10)].Do not administer Avastin to patients with recent history of hemoptysis of 1/2 teaspoon or more of red blood. Discontinue in patients who develop Grades 3-4 hemorrhage.. 5.4 Arterial Thromboembolic Events. Serious, sometimes fatal, arterial thromboembolic events (ATE) including cerebral infarction, transient ischemic attacks, myocardial infarction, and angina, occurred at higher incidence in patients receiving Avastin compared to patients receiving chemotherapy. Across clinical studies, the incidence of Grades 3-5 ATE was 5% in patients receiving Avastin with chemotherapy compared to <=2% in patients receiving chemotherapy alone; the highest incidence occurred in patients with GBM. The risk of developing ATE was increased in patients with history of arterial thromboembolism, diabetes, or >65 years [see Use in Specific Populations (8.5)]. Discontinue in patients who develop severe ATE. The safety of reinitiating Avastin after an ATE is resolved is not known.. 5.5 Venous Thromboembolic Events. An increased risk of venous thromboembolic events (VTE) was observed across clinical studies [see Adverse Reactions (6.1)]. In Study GOG-0240, Grades 3-4 VTE occurred in 11% of patients receiving Avastin with chemotherapy compared with 5% of patients receiving chemotherapy alone. In EORTC 26101, the incidence of Grades 3-4 VTE was 5% in patients receiving Avastin with chemotherapy compared to 2% in patients receiving chemotherapy alone.Discontinue Avastin in patients with Grade VTE, including pulmonary embolism. 5.6 Hypertension. Severe hypertension occurred at higher incidence in patients receiving Avastin as compared to patients receiving chemotherapy alone. Across clinical studies, the incidence of Grades 3-4 hypertension ranged from 5% to 18%.Monitor blood pressure every two to three weeks during treatment with Avastin. Treat with appropriate anti-hypertensive therapy and monitor blood pressure regularly. Continue to monitor blood pressure at regular intervals in patients with Avastin-induced or -exacerbated hypertension after discontinuing Avastin. Withhold Avastin in patients with severe hypertension that is not controlled with medical management; resume once controlled with medical management. Discontinue in patients who develop hypertensive crisis or hypertensive encephalopathy.. 5.7 Posterior Reversible Encephalopathy Syndrome. Posterior reversible encephalopathy syndrome (PRES) was reported in 0.5% of patients across clinical studies. The onset of symptoms occurred from 16 hours to year after the first dose. PRES is neurological disorder which can present with headache, seizure, lethargy, confusion, blindness and other visual and neurologic disturbances. Mild to severe hypertension may be present. Magnetic resonance imaging is necessary to confirm the diagnosis of PRES.Discontinue Avastin in patients who develop PRES. Symptoms usually resolve or improve within days after discontinuing Avastin, although some patients have experienced ongoing neurologic sequelae. The safety of reinitiating Avastin in patients who developed PRES is not known.. 5.8 Renal Injury and Proteinuria. The incidence and severity of proteinuria was higher in patients receiving Avastin as compared to patients receiving chemotherapy. Grade (defined as urine dipstick 4+ or 3.5 grams of protein per 24 hours) to Grade (defined as nephrotic syndrome) ranged from 0.7% to 7% in clinical studies. The overall incidence of proteinuria (all grades) was only adequately assessed in Study BO17705, in which the incidence was 20%. Median onset of proteinuria was 5.6 months (15 days to 37 months) after initiating Avastin. Median time to resolution was 6.1 months (95% CI: 2.8, 11.3). Proteinuria did not resolve in 40% of patients after median follow-up of 11.2 months and required discontinuation of Avastin in 30% of the patients who developed proteinuria [see Adverse Reactions (6.1)].In an exploratory, pooled analysis of patients from seven randomized clinical studies, 5% of patients receiving Avastin with chemotherapy experienced Grades 2-4 (defined as urine dipstick 2+ or greater or 1 gram of protein per 24 hours or nephrotic syndrome) proteinuria. Grades 2-4 proteinuria resolved in 74% of patients. Avastin was reinitiated in 42% of patients. Of the 113 patients who reinitiated Avastin, 48% experienced second episode of Grades 2-4 proteinuria.Nephrotic syndrome occurred in 1% of patients receiving Avastin across clinical studies, in some instances with fatal outcome. In published case series, kidney biopsy of patients with proteinuria showed findings consistent with thrombotic microangiopathy. Results of retrospective analysis of 5805 patients who received Avastin with chemotherapy and 3713 patients who received chemotherapy alone, showed higher rates of elevated serum creatinine levels (between 1.5 to 1.9 times baseline levels) in patients who received Avastin. Serum creatinine levels did not return to baseline in approximately one-third of patients who received Avastin.Monitor proteinuria by dipstick urine analysis for the development or worsening of proteinuria with serial urinalyses during Avastin therapy. Patients with 2+ or greater urine dipstick reading should undergo further assessment with 24-hour urine collection. Withhold for proteinuria greater than or equal to grams per 24 hours and resume when less than grams per 24 hours. Discontinue in patients who develop nephrotic syndrome.Data from postmarketing safety study showed poor correlation between UPCR (Urine Protein/Creatinine Ratio) and 24-hour urine protein [Pearson Correlation 0.39 (95% CI: 0.17, 0.57)]. 5.9 Infusion-Related Reactions. Infusion-related reactions reported across clinical studies and postmarketing experience include hypertension, hypertensive crises associated with neurologic signs and symptoms, wheezing, oxygen desaturation, Grade hypersensitivity, chest pain, headaches, rigors, and diaphoresis. In clinical studies, infusion-related reactions with the first dose occurred in 3% of patients and severe reactions occurred in 0.4% of patients.Decrease the rate of infusion for mild, clinically insignificant infusion-related reactions. Interrupt the infusion in patients with clinically significant infusion-related reactions and consider resuming at slower rate following resolution. Discontinue in patients who develop severe infusion-related reaction and administer appropriate medical therapy (e.g., epinephrine, corticosteroids, intravenous antihistamines, bronchodilators and/or oxygen).. 5.10 Embryo-Fetal Toxicity. Based on its mechanism of action and findings from animal studies, Avastin may cause fetal harm when administered to pregnant women. Congenital malformations were observed with the administration of bevacizumab to pregnant rabbits during organogenesis every days at dose as low as clinical dose of 10 mg/kg. 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 fetus. Advise females of reproductive potential to use effective contraception during treatment with Avastin and for months after the last dose [see Use in Specific Populations (8.1, 8.3)]. 5.11 Ovarian Failure. The incidence of ovarian failure was 34% vs. 2% in premenopausal women receiving Avastin with chemotherapy as compared to those receiving chemotherapy alone for adjuvant treatment of solid tumor. After discontinuing Avastin, recovery of ovarian function at all time points during the post-treatment period was demonstrated in 22% of women receiving Avastin. Recovery of ovarian function is defined as resumption of menses, positive serum -HCG pregnancy test, or an FSH level 30 mIU/mL during the post-treatment period. Long-term effects of Avastin on fertility are unknown. Inform females of reproductive potential of the risk of ovarian failure prior to initiating Avastin [see Adverse Reactions (6.1), Use in Specific Populations (8.3)]. 5.12 Congestive Heart Failure (CHF). Avastin is not indicated for use with anthracycline-based chemotherapy. The incidence of Grade >= left ventricular dysfunction was 1% in patients receiving Avastin compared to 0.6% of patients receiving chemotherapy alone. Among patients who received prior anthracycline treatment, the rate of CHF was 4% for patients receiving Avastin with chemotherapy as compared to 0.6% for patients receiving chemotherapy alone.In previously untreated patients with hematological malignancy, the incidence of CHF and decline in left ventricular ejection fraction (LVEF) were increased in patients receiving Avastin with anthracycline-based chemotherapy compared to patients receiving placebo with the same chemotherapy regimen. The proportion of patients with decline in LVEF from baseline of >= 20% or decline from baseline of 10% to 50%, was 10% in patients receiving Avastin with chemotherapy compared to 5% in patients receiving chemotherapy alone. Time to onset of left-ventricular dysfunction or CHF was to months after the first dose in at least 85% of the patients and was resolved in 62% of the patients who developed CHF in the Avastin arm compared to 82% in the placebo arm. Discontinue Avastin in patients who develop CHF.
