  • Discontinue in patients with wound healing complications requiring medical intervention
• Hemorrhage
  • Severe or fatal hemorrhage, including hemoptysis, GI bleeding, hematemesis, central nervous system hemorrhage, epistaxis, and vaginal bleeding, occurred up to 5-fold more frequently in patients receiving Avastin. In clinical studies, the incidence of grade ≥3 hemorrhagic events among patients receiving Avastin ranged from 0.4% to 7%
  • Do not administer Avastin to patients with serious hemorrhage or a recent history of hemoptysis (≥1/2 tsp of red blood)
  • Discontinue Avastin in patients who develop grade 3-4 hemorrhage

  • Non-GI fistulae (<1% to 1.8%, highest in patients with cervical cancer)
  • Arterial thromboembolic events (grade ≥3, 5%, highest in patients with GBM)
  • Renal injury and proteinuria
    • Grade 3–4 proteinuria ranged from 0.7% to 7% in clinical studies
    • Nephrotic syndrome (<1%)
• Additional serious adverse events with increased incidence in the Avastin-treated arm vs chemotherapy arm included:
  • Venous thromboembolism (grade ≥3, 11% seen in GOG-0240)
  • Hypertension (grade 3–4, 5%–18%)
  • Posterior reversible encephalopathy syndrome (PRES) (<0.5%)
  • Congestive heart failure (CHF): grade >3 left ventricular dysfunction (1%)

• Avoid use 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
• Inform females of reproductive potential of the risk of ovarian failure prior to initiating treatment with Avastin
