Neovascular AMD: Bevacizumab Injection Increases Angiogenic Biomarkers

Dr. Thiago Cabral

Neovascular age-related macular degeneration (nAMD) is induced by the development of new abnormal ‘leaky’ blood vessels in the choroid and retina, when the balance of pro- and anti-angiogenic factors is upset. Vascular endothelial growth factor (VEGF) is considered a critical modulator of angiogenesis and is related to induction of endothelial cell migration and proliferation after hypoxia. The development of anti-VEGF agents, such as bevacizumab (Avastin®), ranibizumab (Lucentis®) and aflibercept (Eylea®), revolutionized the treatment of nAMD.

Regeneron's PANORAMA study for Eylea in Diabetic Retinopathy shows Promise

(c) PMLive

Regeneron Pharmaceuticals, Inc. announced positive topline data from its Phase III PANORAMA clinical trial of Eylea (aflibercept) injection in moderately severe to severe non-proliferative diabetic retinopathy. Diabetic retinopathy, which affects about eight million people, is the result of microvascular damage to the blood vessels in the retina related to lack of blood sugar control in diabetic patients.

Researchers identify a key protein in Diabetic Retinopathy

Researchers at University of Utah Health have identified a protein, ADP-ribosylation factor 6 (ARF6), which is crucial for the development of diabetic retinopathy. Published in The Journal of Clinical Investigation, they identified a compound, NAV-2729, which inhibits or blocks ARF6, reducing the chances of development of diabetic retinopathy.

Study Finds Anti-VEGF Therapy Safer Before Steroids for Retinal Vein Occlusion

In results from a new study that was presented at EURETINA, Aflibercept and ranibizumab were found to be safer than dexamethasone intravitreal implants for the treatment of central retinal vein occlusion.
