Summary of "Innovative therapies for neovascular age-related macular degeneration."

: Investigational anti-VEGF treatments for neovascular age-related macular degeneration (nAMD) aim to improve visual outcomes and reduce treatment burden; these include long-acting agents, combination strategies, topical agents, sustained-release, and genetic therapies. : The authors provide a comprehensive review of investigational therapies for nAMD, focusing on therapies currently in clinical trial. : Long-acting anti-VEGF agents have demonstrated promising results in phase 3 studies, and include Brolucizumab, a single-chain antibody fragment, and Abicipar, a designed ankyrin repeat protein (DARPin). Other unique anti-VEGF agents in current trials include Conbercept - a fusion protein of the VEGF receptor domains, KSI-301 - an anti-VEGF antibody biopolymer conjugate, and OPT-302 - an inhibitor of VEGF-C/D. Strategies to activate the Tie-2 receptor, some in combination with VEGF inhibition, are of interest, with recent trials of Faricimab, ARP-1536, and nesvacumab. Topical anti-VEGF ± anti-PDGF agents, such as pazopanib, squalamine lactate, regorafenib, and LHA510 have shown limited efficacy and/or have not been advanced, although PAN-90806 continues to advance with promising initial results. Sustained-release anti-VEGF treatments, to address treatment burden, include the ranibizumab Port Delivery System, GB-102, NT-503, hydrogel depot, Durasert, and ENV1305. Similarly, genetic therapies, including RGX-314 and ADVM-022, aim to provide sustained anti-VEGF expression from the retina.

Medical and Biotech [MESH] Definitions

A form of MACULAR DEGENERATION also known as dry macular degeneration marked by occurrence of a well-defined progressive lesion or atrophy in the central part of the RETINA called the MACULA LUTEA. It is distinguishable from WET MACULAR DEGENERATION in that the latter involves neovascular exudates.

A recombinant humanized monoclonal antibody fragment that binds VEGF-A to prevent its binding to VEGFR-1 and VEGFR-2 receptors. This activity reduces vessel permeability and angiogenesis in the treatment of neovascular age-related MACULAR DEGENERATION.

Specialized ophthalmic technique used in the surgical repair and or treatment of disorders that include retinal tears or detachment; MACULAR HOLES; hereditary retinal disease; AIDS-related retinal infections; ocular tumors; MACULAR DEGENERATION; DIABETIC RETINOPATHY; and UVEITIS.

A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p304)

A form of RETINAL DEGENERATION in which abnormal CHOROIDAL NEOVASCULARIZATION occurs under the RETINA and MACULA LUTEA, causing bleeding and leaking of fluid. This leads to bulging and or lifting of the macula and the distortion or destruction of central vision.
