• Gastrointestinal (GI) perforation
  • Serious and sometimes fatal GI perforation occurred at a higher incidence in bevacizumab-treated patients compared to patients treated with chemotherapy
  • The incidence of GI perforation ranged from 0.3% to 3% across clinical studies
  • Discontinue MVASI™ in patients with GI perforation

  • 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 bevacizumab. In clinical studies, the incidence of grade ≥3 hemorrhagic events among patients receiving bevacizumab ranged from 0.4% to 7%
  • Do not administer MVASI™ to patients with serious hemorrhage or a recent history of hemoptysis (≥1/2 tsp of red blood)
  • Discontinue MVASI™ in patients who develop grade 3–4 hemorrhage
• Additional serious and sometimes fatal adverse events with increased incidence in the bevacizumab-treated arm vs chemotherapy arm included:
  • 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 bevacizumab-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) (1%)
• Infusion reactions with the first dose of bevacizumab occurred in <3% of patients, and severe reactions occurred in 0.2% of patients
• 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 MVASI™

Pregnancy warning

• Based on the mechanism of action and animal studies, MVASI™ may cause fetal harm when administered to pregnant women
• Advise female patients that MVASI™ may cause fetal harm, and to inform their healthcare provider of a known or suspected pregnancy
• Advise females of reproductive potential to use effective contraception during treatment with MVASI™ and for 6 months after the last dose
• Advise nursing women that breastfeeding is not recommended during treatment with MVASI™ and for 6 months following their last dose of treatment
• MVASI™ may impair fertility

Most common adverse events

• Across studies, the most common adverse reactions observed in bevacizumab-treated patients at a rate >10% were:
  • Epistaxis
  • Headache
  • Hypertension
  • Rhinitis
  • Proteinuria
  • Taste alteration
  • Dry skin
  • Rectal hemorrhage
  • Lacrimation disorder
  • Back pain
  • Exfoliative dermatitis
• Across all studies, bevacizumab was discontinued in 8% to 22% of patients because of adverse reactions

Indication-specific adverse events

• In CC, grade 3 or 4 adverse reactions in Study GOG-0240, occurring at a higher incidence (≥2%) in 218 patients receiving bevacizumab plus chemotherapy compared to 222 patients receiving chemotherapy alone, were abdominal pain (12% vs 10%), 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%), hypertension (11% vs 0.5%), thrombosis (8% vs 3%), 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%)
• In mRCC, the most common grade 3–5 adverse events in AVOREN, occurring at a >2% higher incidence in bevacizumab-treated patients vs controls, 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)
• In rGBM Study EORTC 26101, 22% of patients discontinued treatment in the bevacizumab with lomustine arm due to adverse reactions compared with 10% of patients in the lomustine arm. In patients receiving bevacizumab with lomustine, the adverse reaction profile was similar to that observed in other approved indications
• In NSCLC, grade 3–5 (nonhematologic) and grade 4–5 (hematologic) adverse events in Study E4599 occurring at a ≥2% higher incidence in bevacizumab-treated patients vs controls were neutropenia (27% vs 17%), fatigue (16% vs 13%), hypertension (8% vs 0.7%), infection without neutropenia (7% vs 3%), venous thromboembolism (5% vs 3%), febrile neutropenia (5% vs 2%), pneumonitis/pulmonary infiltrates (5% vs 3%), infection with grade 3 or 4 neutropenia (4% vs 2%), hyponatremia (4% vs 1%), headache (3% vs 1%), and proteinuria (3% vs 0%)
• In first-line mCRC, the most common grade 3–4 events in Study 2107, which occurred at a ≥2% higher incidence in the bevacizumab plus IFL vs IFL groups, were asthenia (10% vs 7%), abdominal pain (8% vs 5%), pain (8% vs 5%), hypertension (12% vs 2%), deep vein thrombosis (9% vs 5%), intra-abdominal thrombosis (3% vs 1%), syncope (3% vs 1%), diarrhea (34% vs 25%), constipation (4% vs 2%), leukopenia (37% vs 31%), and neutropenia (21% vs 14%)
• In second-line mCRC, the most common grade 3–5 (nonhematologic) and 4–5 (hematologic) events in Study E3200, which occurred at a higher incidence (≥2%) in the bevacizumab plus FOLFOX4 vs FOLFOX4 groups, 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 underestimate the true adverse event rates due to the reporting mechanisms used in this study
