    1. Bevacizumab
    2. Ramucirumab
  2. Non-Small Cell Lung Cancer
    1. Bevacizumab
    2. Ramucirumab
  3. Glioblastoma (recurrent)
    1. Bevacizumab
  4. Renal Cell Carcinoma (metastatic)
    1. Bevacizumab
  5. Cervical Cancer (advanced, recurrent)
    1. Bevacizumab
  6. Ovarian Cancer, Fallopian Tube Cancer or Primary Peritoneal Cancer (resistant)
    1. Bevacizumab
  7. Hepatocellular Carcinoma
    1. Bevacizumab
    2. Ramucirumab
  8. Gastric Cancer (advanced)
    1. Ramucirumab
  9. Soft-Tissue Sarcoma
    1. Bevacizumab (off-label)
  10. Age-Related Macular Degeneration
    1. See VEGF Inhibitor Intravitreal Injection
    2. Bevacizumab (off-label)
  • Mechanism
  1. Vascular Endothelial Growth Factor Receptor (VEGF, VEGFR)
    1. See Tyrosine Kinase
    2. Angiogenesis signaling Protein
      1. Vascular Endothelial Growth Factors (VEGF) are pro-angiogenic Cytokines
      2. Bind to VEGF receptors on Tyrosine Kinases to initiate Angiogenesis
      3. Target in some Targeted Cancer Therapy (as below)
    3. Other functions
      1. Monocyte activation and differentiation (VEGFR 1)
      2. Also used in Age-Related Macular Degeneration as a VEGF Inhibitor Intravitreal Injection
  2. VEGFR Inhibitors
    1. VEGF Inhibitors suppress Angiogenesis
    2. Recombinant Monoclonal Antibody against Vascular Endothelial Growth Factor (VEGF)
    3. Inhibit VEGF receptor binding, interfering with the growth and maintenance of neoplastic vessels
  3. Other Inhibitors of VEGFR
    1. See Small Molecule VEGF Inhibitor
  • Medications
  1. Bevacizumab (Avastin) IV Infusion
    1. Risk of CV events, VTE, bleeding, MAHA, GI perforation, Proteinuria, Hypertension, poor Wound Healing
