Important Safety Information

Serious adverse reactions (Warnings and Precautions)

  • Serious and sometimes fatal adverse reactions with increased incidence in the bevacizumab-treated arm vs chemotherapy arm included:
    • Gastrointestinal (GI) perforation ranged from 0.3% to 3% of patients across clinical studies

Pregnancy warning

  • Based on the mechanism of action and animal studies, MVASI® may cause fetal harm
  • 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 of MVASI®
  • Advise nursing women not to breastfeed during treatment with MVASI® and for 6 months following their last dose of treatment

    • Proteinuria
    • Taste alteration
    • Dry skin
    • 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 reactions

  • 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 reactions 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, the incidence of Grade 3–4 VTE was 5% in patients receiving bevacizumab with chemotherapy compared to 2% in patients receiving chemotherapy alone. In this study, 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 reactions 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 reactions 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) reactions 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
  • When continued beyond first progression in MCRC, no new safety signals were observed in the TML study (ML18147) when bevacizumab was administered in second-line MCRC patients who progressed on a bevacizumab containing regimen in first-line MCRC. The safety data was consistent with the known safety profile established in first- and second-line MCRC
