What are the uses of this medicine?[edit | edit source]

Bevacizumab (Avastin) is indicated for the treatment of:

Epithelial ovarian, fallopian tube, or primary peritoneal cancer:

  • in combination with carboplatin and paclitaxel, followed by Avastin as a single agent, for stage III or IV disease following initial surgical resection.
  • in combination with paclitaxel, pegylated liposomal doxorubicin, or topotecan for platinum-resistant recurrent disease who received no more than 2 prior chemotherapy regimens.
  • in combination with carboplatin and paclitaxel or carboplatin and gemcitabine, followed by Avastin as a single agent, for platinum-sensitive recurrent disease.

Hepatocellular Carcinoma (HCC):

  • in combination with atezolizumab for the treatment of patients with unresectable or metastatic HCC who have not received prior systemic therapy.

Limitations of Use:


How does this medicine work?[edit | edit source]

  • Bevacizumab (be” va siz’ ue mab) is a recombinant humanized monoclonal IgG1 antibody which is directed at and binds avidly to circulating vascular endothelial growth factor (VEGF).
  • Receptors for VEGF (Flt-1 and KDR) are present on endothelial cells, and the engagement of VEGF with these receptors promotes angiogenesis. Inhibition of VEGF decreases formation of new blood vessels, which plays an important role in growth and spread of cancer cells.
  • When used in combination with other antineoplastic agents, bevacizumab has been shown to extend both recurrence-free as well as overall patient survival in several forms of advanced cancer.

Who Should Not Use this medicine ?[edit | edit source]

  • This medicine have no usage limitations.


What drug interactions can this medicine cause?[edit | edit source]

  • No clinically meaningful drug interactions have been observed.

Is this medicine FDA approved?[edit | edit source]

  • Bevacizumab was approved in the United States in 2004 for use in metastatic colon cancer.
  • Indications were subsequently extended to selected forms of non-small cell lung cancer, breast and renal cancer and glioblastoma.
  • However, the indication for use in breast cancer was withdrawn in 2011 because of lack of evidence that bevacizumab extended overall patient survival.

What side effects can this medication cause?[edit | edit source]

The most common side effects of this medicine include:

What special precautions should I follow?[edit | edit source]

  • Serious, and sometimes fatal, gastrointestinal perforation occurred at a higher incidence in patients receiving Avastin compared to patients receiving chemotherapy. Discontinue for gastrointestinal perforations, tracheoesophageal fistula, grade 4 fistula, or fistula formation involving any organ.
  • 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 Avastin for at least 28 days following a major surgery, and until adequate wound healing. The safety of resumption of AVASTIN after resolution of wound healing complication has not been established. Discontinue for wound healing complication of necrotizing fasciitis.
  • Avastin can result in two distinct patterns of bleeding: minor hemorrhage, which is most commonly Grade 1 epistaxis, and serious hemorrhage, which in some cases has been fatal. Severe or fatal hemorrhages have occurred. Do not administer for recent hemoptysis. Discontinue for Grade 3-4 hemorrhage.
  • Serious, sometimes fatal, arterial thromboembolic events (ATE) including cerebral infarction, transient ischemic attacks, myocardial infarction, and angina, occurred at a higher incidence in patients receiving Avastin compared to patients receiving chemotherapy. Discontinue for severe ATE.
  • An increased risk of venous thromboembolic events (VTE) was observed across clinical studies. Discontinue for Grade 4 VTE.
  • Severe hypertension occurred at a higher incidence in patients receiving Avastin as compared to patients receiving chemotherapy alone. Monitor blood pressure and treat hypertension. Withhold if not medically controlled; resume once controlled. Discontinue for hypertensive crisis or hypertensive encephalopathy
  • Posterior reversible encephalopathy syndrome (PRES) was reported. Discontinue Avastin in patients who develop PRES.
  • The incidence and severity of proteinuria was higher in patients receiving Avastin as compared to patients receiving chemotherapy. Monitor urine protein. Discontinue for nephrotic syndrome. Withhold until less than 2 grams of protein in urine.
  • Infusion-related reactions reported with Avastin. Decrease rate for infusion-related reactions. Discontinue for severe infusion-related reactions and administer medical therapy.
  • Avastin may cause fetal harm. Advise females of potential risk to fetus and need for use of effective contraception.
  • Based on its mechanism of action and findings from animal studies, Avastin may cause fetal harm when administered to pregnant women. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with Avastin and for 6 months after the last dose.
  • Avastin is not indicated for use with anthracycline-based chemotherapy. The incidence of Grade ≥ 3 left ventricular dysfunction was in patients receiving Avastin compared to patients receiving chemotherapy alone. Discontinue Avastin in patients who develop CHF.
