Bevacizumab (Avastin - Genentech) is a recombinant humanized monoclonal antibody that binds to vascular endothelial growth factor and prevents it from binding to receptors on endothelial cells, inhibiting formation of new blood vessels. Previously approved by the FDA for use in combination regimens for first-line treatment of metastatic colon cancer and metastatic non-small cell lung cancer, and used off-label for treatment of agerelated macular degeneration, it has now also been approved by the FDA for use in combination with paclitaxel (Taxol, and others) for first-line treatment of...

Vascular endothelial growth factor (VEGF) is a principal mediator of neovascularization in wet age-related macular degeneration (AMD) and diabetic macular edema. It induces angiogenesis and increases vascular permeability and inflammation. VEGF inhibitors reduce leakage from blood vessels, prevent proliferation of new abnormal vessels, decrease swelling of the retina, and improve visual acuity in patients with neovascular (wet) AMD and diabetic macular edema. These drugs are given as periodic intravitreal injections with topical anesthesia.

Cetuximab (Erbitux - ImClone Systems/Bristol-Myers Squibb), an epidermal growth factor receptor (EGFR) inhibitor, and bevacizumab (Avastin - Genentech), the first vascular endothelial growth factor angiogenesis inhibitor, have recently been approved by the FDA for treatment of patients with metastatic colorectal cancer. Cetuximab is approved for treatment of patients with EGFR-expressing tumors, either in combination regimens with irinotecan (Camptosar)when the cancer has progressed on irinotecan-based therapy, or as monotherapy for those who cannot tolerate irinotecan. Bevacizumab is approved...

Ziv-aflibercept (Zaltrap – Sanofi/Regeneron), a vascular endothelial growth factor (VEGF) inhibitor, has been approved by the FDA for use in combination with 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) for treatment of metastatic colorectal cancer that is resistant to or has progressed following an oxaliplatin-containing regimen. It is the same drug as aflibercept, which was approved last year as an intravitreal injection (Eylea) for treatment of neovascular (wet) agerelated macular degeneration (AMD). Ziv-aflibercept is the second VEGF inhibitor approved for treatment...

The FDA has approved aflibercept (a flib’ er sept; Eylea – Regeneron) for treatment of neovascular (wet) age-related macular degeneration (AMD).

The FDA has approved ranibizumab (Lucentis - Genentech) as an intravitreal injection for treatment of neovascular (wet) age-related macular degeneration (AMD). Ranibizumab is a derivative of bevacizumab (Avastin), which is FDA-approved for intravenous treatment of metastatic colorectal cancer and nonsmall cell lung cancer, but has also been used off label for intravitreal treatment of neovascular AMD.

This issue includes reviews of drugs for glaucoma, age-related macular degeneration (AMD), bacterial conjunctivitis, and dry eye disease. Allergic conjunctivitis is reviewed in a separate issue.

Age-related macular degeneration (AMD) has two major forms: dry or non-neovascular (~90% of patients) and wet or neovascular (~10% of patients).

The FDA has approved Lonsurf (Taiho Oncology), a combination of the thymidine-based nucleoside analog trifluridine and the thymidine phosphorylase inhibitor tipiracil, for oral treatment of metastatic colorectal cancer. Trifluridine is incorporated into DNA, interfering with DNA synthesis and inhibiting cell proliferation. Tipiracil inhibits the metabolism of trifluridine. The combination is only approved for use in patients who were previously treated with a fluoropyrimidine (fluorouracil or capecitabine), oxaliplatin, irinotecan, an anti-VEGF biological such as bevacizumab, and, if the tumor...

Axitinib (Inlyta – Pfizer), an oral tyrosine kinase inhibitor, has been approved by the FDA for treatment of advanced renal cell carcinoma after failure of one prior systemic therapy. It is the fourth oral tyrosine kinase inhibitor to be approved for treatment of advanced renal cell carcinoma.
