- Vascular Endothelial Growth Factor (VEGF) Inhibitor
Bevacizumab is a recombinant, humanized monoclonal antibody which binds to, and neutralizes, vascular endothelial growth factor (VEGF), preventing its association with endothelial receptors, Flt-1 and KDR. VEGF binding initiates angiogenesis (endothelial proliferation and the formation of new blood vessels). The inhibition of microvascular growth is believed to retard the growth of all tissues (including metastatic tissue).
Vd: 46 mL/kg
Pediatric patients (age: 1 to 21 years): Median: 11.8 days (range: 4.4 to 14.6 days) (Glade Bender 2008)
Adults: ~20 days (range: 11 to 50 days)
Intravitreal: ~5 to 10 days (Bakri 2007; Krohne 2008)
Special Populations: Gender
Men had a higher clearance and larger volume of distribution in the central compartment when compared with women. There is no evidence that this difference decreases the efficacy of bevacizumab in men.
Special Populations Note
Tumor burden: Patients with a higher tumor burden had a higher clearance of bevacizumab compared with patients who had a tumor burden below the median. There is no evidence suggesting that this difference leads to decreased efficacy.

There are no dosage adjustments provided in the manufacturer's labeling.
Dosing: Hepatic Impairment
There are no dosage adjustments provided in the manufacturer's labeling.
Dosing: Adjustment for Toxicity
IV administration (systemic): There are no recommended dosage reductions. Temporary suspension is recommended for severe infusion reactions, at least 4 weeks prior to (and after) elective surgery, in moderate-to-severe proteinuria (in most studies, treatment was withheld for ≥2 g proteinuria/24 hours), or in patients with severe hypertension which is not controlled with medical management. Permanent discontinuation is recommended (by the manufacturer) in patients who develop wound dehiscence and wound healing complications requiring intervention, necrotizing fasciitis, fistula (gastrointestinal and nongastrointestinal), gastrointestinal perforation, intra-abdominal abscess, hypertensive crisis, hypertensive encephalopathy, serious bleeding/hemorrhage, severe arterial thromboembolic event, life-threatening (grade 4) venous thromboembolic events (including pulmonary embolism), nephrotic syndrome, or PRES.
Dilute in 100 mL NS prior to infusion (the manufacturer recommends a total volume of 100 mL). Do not mix with dextrose-containing solutions.
IV: Infuse the initial dose over 90 minutes. The second infusion may be shortened to 60 minutes if the initial infusion is well tolerated. The third and subsequent infusions may be shortened to 30 minutes if the 60-minute infusion is well tolerated. Monitor closely during the infusion for signs/symptoms of an infusion reaction. After tolerance at the 90-, 60-, and 30-minute infusion rates has been established, some institutions use an off-label 10-minute infusion rate (0.5 mg/kg/minute) for bevacizumab dosed at 5 mg/kg (Reidy 2007). In a study evaluating the safety of the 0.5 mg/kg/minute infusion rate, proteinuria and hypertension incidences were not increased with the shorter infusion time (Shah 2013). Do not administer IV push. Do not administer with dextrose solutions. Temporarily withhold bevacizumab for 4 weeks prior to elective surgery and for at least 4 weeks (and until the surgical incision is fully healed) after surgery.
Intravitreal injection (off-label use/route): Adequate local anesthesia and a topical broad-spectrum antimicrobial agent should be administered prior to the procedure.

Concerns related to adverse effects:
• Fistula/abscess formation: Gastrointestinal (GI) fistula (including enterocutaneous, esophageal, duodenal, and rectal fistulas), and intra-abdominal abscess have been reported in patients receiving bevacizumab for colorectal cancer, ovarian cancer, and other cancers (not related to treatment duration). Non-GI fistula formation (including tracheoesophageal, bronchopleural, biliary, vaginal, vesical, renal, bladder, and female tract fistulas) has been observed (rarely fatal), most commonly within the first 6 months of treatment. GI-vaginal fistulas have been reported in cervical cancer patients, all of whom had received prior pelvic radiation; patients may also have bowel obstructions requiring surgical intervention and diverting ostomies. Permanently discontinue in patients who develop internal organ fistulas, tracheoesophageal (TE) fistula, or any grade 4 fistula.
• Gastrointestinal perforation: [US Boxed Warning]: GI perforation, (sometimes fatal) has occurred in 0.3% to 3.2% of clinical study patients receiving bevacizumab; discontinue (permanently) if GI perforation occurs. All cervical cancer patients with GI perforation had a history of prior pelvic radiation. GI perforation was observed in patients with platinum-resistant ovarian cancer, although patients with evidence of recto-sigmoid involvement (by pelvic exam), bowel involvement (on CT scan), or clinical symptoms of bowel obstruction were excluded from the study; avoid bevacizumab use in these ovarian cancer patient populations. Most cases occur within 50 days of treatment initiation; monitor patients for signs/symptoms (eg, fever, abdominal pain with constipation and/or nausea/vomiting).
• Heart failure: Among approved and nonapproved uses evaluated thus far, the incidence of heart failure (HF) and/or left ventricular dysfunction (including LVEF decline) is higher in patients receiving bevacizumab plus chemotherapy when compared to chemotherapy alone. Use with caution in patients with cardiovascular disease. The safety of therapy resumption or continuation in patients with cardiac dysfunction has not been studied. In studies of patients with metastatic breast cancer (an off-label use), the incidence of grades 3 or 4 HF was increased in patients receiving bevacizumab plus paclitaxel when compared to the control arm. Patients with metastatic breast cancer who received prior anthracycline therapy had a higher rate of HF compared to those receiving paclitaxel alone (3.8% vs 0.6% respectively). A meta-analysis of 5 studies which enrolled patients with metastatic breast cancer who received bevacizumab suggested an association with an increased risk of heart failure; all trials included in the analysis enrolled patients who either received prior or were receiving concurrent anthracycline therapy (Choueiri 2011). In a scientific statement from the American Heart Association, bevacizumab has been determined to be an agent that may either cause reversible direct myocardial toxicity or exacerbate underlying myocardial dysfunction (magnitude: moderate/major) (AHA [Page 2016]).
• Hemorrhage: [US Boxed Warning]: Severe or fatal hemorrhage, including hemoptysis, gastrointestinal bleeding, central nervous system hemorrhage, epistaxis, and vaginal bleeding have been reported (up to 5 times more frequently if receiving bevacizumab). Avoid use in patients with serious hemorrhage or recent hemoptysis (≥2.5 mL blood). Serious or fatal pulmonary hemorrhage has been reported in patients receiving bevacizumab (primarily in patients with non–small cell lung cancer with squamous cell histology [not an FDA-approved indication]). Intracranial hemorrhage, including cases of grade 3 or 4 hemorrhage, has occurred in patients with previously treated glioblastoma. Treatment discontinuation is recommended in all patients with intracranial bleeding or other serious hemorrhage. Use with caution in patients at risk for thrombocytopenia.
• Hypertension: May cause and/or worsen hypertension; the incidence of severe hypertension in increased with bevacizumab. Use caution in patients with preexisting hypertension and monitor BP closely (every 2 to 3 weeks during treatment; regularly after discontinuation if bevacizumab-induced hypertension occurs or worsens). Permanent discontinuation is recommended in patients who experience a hypertensive crisis or hypertensive encephalopathy. Temporarily discontinue in patients who develop uncontrolled hypertension.
• Infusion reactions and hypersensitivity: Infusion reactions (eg, hypertension, hypertensive crisis, wheezing, oxygen desaturation, hypersensitivity [including anaphylactic/anaphylactoid reactions], chest pain, rigors, headache, diaphoresis) may occur with the first infusion (uncommon). Interrupt therapy in patients experiencing severe infusion reactions and administer appropriate therapy; there are no data to address routine premedication use or reinstitution of therapy in patients who experience severe infusion reactions.
• Mortality: Bevacizumab, in combination with chemotherapy (or biologic therapy), is associated with an increased risk of treatment-related mortality; a higher risk of fatal adverse events was identified in a meta-analysis of 16 trials in which bevacizumab was used for the treatment of various cancers (breast cancer, colorectal cancer, non–small cell lung cancer, pancreatic cancer, prostate cancer, and renal cell cancer) and compared to chemotherapy alone (Ranpura 2011).
• Necrotizing fasciitis: Cases of necrotizing fasciitis, including fatalities, have been reported (rarely); usually secondary to wound healing complications, GI perforation or fistula formation. Discontinue in patients who develop necrotizing fasciitis.
• Ocular adverse events: Serious eye infections and vision loss due to endophthalmitis have been reported from intravitreal administration (off-label use/route).
• Osteonecrosis of the jaw (ONJ): According to a position paper by the American Association of Maxillofacial Surgeons (AAOMS), medication-related osteonecrosis of the jaw (MRONJ) has been associated with bisphosphonates and other antiresorptive agents (denosumab), and antiangiogenic agents (eg, bevacizumab, sunitinib) used for the treatment of osteoporosis or malignancy. Antiangiogenic agents, when given concomitantly with antiresorptive agents, are associated with an increased risk of ONJ. Other risk factors for MRONJ include dentoalveolar surgery (eg, tooth extraction, dental implants), pre-existing inflammatory dental disease, and concomitant corticosteroid use. The AAOMS suggests that if medically permissible, initiation of antiangiogenic agents for cancer therapy should be delayed until optimal dental health is attained (if extractions are required, antiangiogenesis therapy should delayed until the extraction site has mucosalized or until after adequate osseous healing). Once antiangiogenic therapy for oncologic disease is initiated, procedures that involve direct osseous injury and placement of dental implants should be avoided. Patients developing ONJ during therapy should receive care by an oral surgeon (AAOMS [Ruggiero 2014]). Cases of non-mandibular ONJ has also been reported in pediatric patients who have received bevacizumab (bevacizumab is not approved for use in pediatric patients).
• Ovarian failure: In premenopausal women receiving bevacizumab in combination with mFOLFOX (fluorouracil/oxaliplatin based chemotherapy) the incidence of ovarian failure (amenorrhea ≥3 months) was higher (34%) compared to women who received mFOLFOX alone (2%). Ovarian function recovered in some patients after treatment was discontinued. Premenopausal women should be informed of the potential risk of ovarian failure.
• Posterior reversible encephalopathy syndrome: Cases of posterior reversible encephalopathy syndrome (PRES) have been reported. Symptoms (which include headache, seizure, confusion, lethargy, blindness and/or other vision, or neurologic disturbances) may occur from 16 hours to 1 year after treatment initiation. Resolution of symptoms usually occurs within days after discontinuation; however, neurologic sequelae may remain. PRES may be associated with hypertension; discontinue therapy and begin management of hypertension, if present. The safety of treatment reinitiation after PRES is not known.
• Proteinuria/nephrotic syndrome: Proteinuria and/or nephrotic syndrome have been associated with use; risks may be increased in patients with history of hypertension. Thrombotic microangiopathy has been associated with bevacizumab-induced proteinuria. Withhold treatment for ≥2 g proteinuria/24 hours and resume when proteinuria is <2 g/24 hours; discontinue in patients with nephrotic syndrome.
• Thromboembolism: Bevacizumab is associated with an increased risk for arterial thromboembolic events (ATE), including cerebral infarction, stroke, MI, TIA, angina, and other ATEs, when used in combination with chemotherapy. History of ATE, diabetes, or ≥65 years of age may present an even greater risk. Although patients with cancer are already at risk for venous thromboembolism (VTE), a meta-analysis of 15 controlled trials has demonstrated an increased risk for VTE in patients who received bevacizumab (Nalluri 2008). Cervical cancer patients receiving bevacizumab plus chemotherapy may be at increased risk of grade 3 or higher VTE compared to those patients who received chemotherapy alone. Permanently discontinue therapy in patients with severe ATE or life-threatening (grade 4) VTE, including pulmonary embolism; the safety of treatment reinitiation after ATE has not been studied.
• Wound dehiscence: [US Boxed Warning]: The incidence of wound healing and surgical complications, including serious and fatal events, is increased in patients who have received bevacizumab; discontinue with wound dehiscence. Although the appropriate interval between withholding bevacizumab and elective surgery has not been defined, bevacizumab should be discontinued at least 28 days prior to surgery and should not be reinitiated for at least 28 days after surgery and until wound is fully healed. In a retrospective review of central venous access device placements (a minor procedure), a greater risk of wound dehiscence was observed when port placement and bevacizumab administration were separated by <14 days (Erinjeri 2011). If possible, it may be more appropriate to wait until at least 6 to 8 weeks after bevacizumab discontinuation for major surgical procedures (Cortes 2012; Gordon 2009).
• CNS metastases: Use with caution in patients with CNS metastases; one case of CNS hemorrhage was observed in a study of NSCLC patients with CNS metastases.
• Renal impairment: An increase in diastolic and systolic blood pressures were noted in a retrospective review of patients with renal insufficiency (CrCl ≤60 mL/minute) who received bevacizumab for renal cell cancer (Gupta 2011).
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Anthracyclines: May potentiate cardiotoxic effects of anthracyclines. HF is more common with prior anthracycline exposure and/or left chest wall irradiation.
• Myelosuppressive chemotherapy: When used in combination with myelosuppressive chemotherapy, increased rates of severe or febrile neutropenia and neutropenic infection were reported.
• Sorafenib: The incidence of hand-foot syndrome is increased in patients treated with bevacizumab plus sorafenib in comparison to those treated with sorafenib monotherapy.
• Sunitinib: Microangiopathic hemolytic anemia (MAHA) has been reported when bevacizumab has been used in combination with sunitinib. Concurrent therapy with sunitinib and bevacizumab is also associated with dose-limiting hypertension in patients with metastatic renal cell cancer.
• Elderly: Use with caution in patients ≥65 years of age; greater risk for adverse events, including arterial thrombotic events and proteinuria. Serious adverse events occurring more frequently in the elderly also include weakness, deep thrombophlebitis, sepsis, hyper-/hypotension, MI, CHF, diarrhea, constipation, anorexia, leukopenia, anemia, dehydration, hypokalemia, and hyponatremia.
Monitor closely during the infusion for signs/symptoms of an infusion reaction. Monitor CBC with differential; signs/symptoms of gastrointestinal perforation, fistula, or abscess (including abdominal pain, constipation, vomiting, and fever); signs/symptoms of bleeding, including hemoptysis, gastrointestinal, and/or CNS bleeding, and/or epistaxis. Monitor blood pressure every 2 to 3 weeks; more frequently if hypertension develops during therapy. Continue to monitor blood pressure after discontinuing due to bevacizumab-induced hypertension. Monitor for proteinuria/nephrotic syndrome with urine dipstick; collect 24-hour urine in patients with ≥2+ reading. Monitor for signs/symptoms of thromboembolism (arterial and venous).
AMD (off-label use): Monitor intraocular pressure and retinal artery perfusion
Hereditary hemorrhagic telangiectasia (off-label use): Cardiac output measurements and liver radiologic response (via ultrasound and hepatic CT exams) prior to initial treatment and at 3 and 6 months following the first dose.
Based on its mechanism of action, bevacizumab would be expected to cause fetal harm if administered to a pregnant woman. Information from postmarketing reports following exposure in pregnancy is limited. Women of reproductive potential should use effective contraception during therapy and for 6 months following the last dose (due to the long half-life of bevacizumab). Bevacizumab treatment may also increase the risk of ovarian failure and impair fertility; long term effects on fertility are not known.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience back pain, muscle pain, joint pain, diarrhea, loss of strength and energy, lack of appetite, hair loss, dry skin, nail changes, change in taste, weight loss, dry mouth, rhinorrhea, insomnia, or change in voice. Have patient report immediately to prescriber signs of infusion reaction, signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; hematuria; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any severe or persistent bleeding), signs of infection, signs of blood clots (numbness or weakness on one side of the body; pain, redness, tenderness, warmth, or swelling in the arms or legs; change in color of an arm or leg; angina; shortness of breath; tachycardia; or coughing up blood), signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of electrolyte problems (mood changes, confusion, muscle pain or weakness, abnormal heartbeat, seizures, lack of appetite, or severe nausea or vomiting), tachycardia, sweating a lot, redness or irritation of palms or soles of feet, signs of necrotizing fasciitis (warm skin with red or purple areas of swelling that spread quickly; ulcers, blisters, black spots on the skin; or any other skin changes), signs of posterior reversible encephalopathy syndrome (confusion, not alert, vision changes, seizures, or severe headache), signs of severe cerebrovascular disease (change in strength on one side is greater than the other, difficulty speaking or thinking, change in balance, or vision changes), severe dizziness, passing out, shortness of breath, excessive weight gain, swelling of arms or legs, severe headache, severe nausea, vomiting, severe constipation, severe abdominal pain, wound healing impairment, or mouth irritation (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
