Aflibercept
Aflibercept, sold under the brand names Eylea and Zaltrap among others, is a medication used to treat wet macular degeneration and metastatic colorectal cancer. It was developed by Regeneron Pharmaceuticals.
It is an inhibitor of vascular endothelial growth factor. Aflibercept is a recombinant fusion protein consisting of the extracellular domains of human VEGF receptor 1 and 2 fused to the Fc portion of human IgG1. By acting as a soluble decoy for the natural VEGF receptors, aflibercept inhibits their activation, thereby reducing angiogenesis.
Medical uses
Aflibercept is indicated for the treatment of people with neovascular age-related macular degeneration, macular edema following retinal vein occlusion, diabetic macular edema, diabetic retinopathy, and retinopathy of prematurity.Aflibercept, in combination with fluorouracil, leucovorin, and irinotecan, is indicated for the treatment of people with metastatic colorectal cancer that is resistant to, or has progressed following, an oxaliplatin-containing regimen.
It is used for the treatment of wet macular degeneration and is administered as an intravitreal injection, that is, into the eye. For cancer treatment, it is given intravenously in combination with fluorouracil, leucovorin, and irinotecan.
In July 2014, aflibercept was approved for the treatment of people with visual impairment due to diabetic macular edema In May 2019, the US FDA expanded the indication for aflibercept to include all stages of diabetic retinopathy.
In February 2023, the US FDA approved aflibercept as a treatment for retinopathy of prematurity.
Contraindications
Aflibercept is contraindicated in people with infections or active inflammations of or near the eye, while aflibercept has no contraindications.Adverse effects
Common adverse effects of the eye formulation include conjunctival hemorrhage, eye pain, cataract, vitreous detachment, floaters, and ocular hypertension.Aflibercept has adverse effects typical of anti-cancer drugs, such as reduced blood cell count, gastrointestinal disorders like diarrhea and abdominal pain, and fatigue. Another common effect is hypertension.
Interactions
No interactions are described for either formulation.Mechanism of action
In wet macular degeneration, abnormal blood vessels grow in the choriocapillaris, a layer of capillaries in the eye, leading to blood and protein leakage below the macula.Aflibercept binds to circulating VEGFs and acts like a "VEGF trap". It thereby inhibits the activity of the vascular endothelial growth factor subtypes VEGF-A and VEGF-B, as well as to placental growth factor, inhibiting the growth of new blood vessels in the choriocapillaris or the tumour, respectively.
Composition
Aflibercept is a recombinant fusion protein consisting of vascular endothelial growth factor -binding portions from the extracellular domains of human VEGF receptors 1 and 2, that are fused to the Fc portion of the human IgG1 immunoglobulin.History
Regeneron commenced clinical testing of aflibercept in cancer in 2001. In 2003, Regeneron signed a major deal with Aventis to develop aflibercept in the field of cancer. In 2004 Regeneron started testing the compound, locally delivered, in proliferative eye diseases, and in 2006 Regeneron and Bayer signed an agreement to develop the eye indications.Society and culture
Legal status
In November 2011, the US Food and Drug Administration approved aflibercept for the treatment of wet macular degeneration.In August 2012, the US FDA approved aflibercept for use in combination with 5-fluorouracil, folinic acid and irinotecan to treat adults with metastatic colorectal cancer that is resistant to, or has progressed following, an oxaliplatin‑containing regimen. To avoid confusion with the version that is injected into the eye, the FDA assigned a new name, ziv-aflibercept, to the active ingredient.
In November 2012, the European Medicines Agency authorized aflibercept for the treatment of wet macular degeneration.
In February 2013, the European Medicines Agency authorized aflibercept for the treatment of adults with metastatic colorectal cancer for whom treatment based on oxaliplatin has not worked or the cancer got worse. Aflibercept is used with irinotecan, 5-fluorouracil, and folinic acid.
In August 2023, the FDA approved aflibercept for the treatment of wet age-related macular degeneration, diabetic macular edema, and diabetic retinopathy.
