Continuous Suppression of Pathological Retinal and Choroidal Neovascularization in Cynomolgus Monkeys via Noninvasive Ophthalmic Delivery of a Novel Anti‐VEGFA Nanobody and Proprietary Penetratin Analog Formulation

open access: yesAdvanced Science, EarlyView.
Pathological retinal/choroidal neovascularization drives vision loss in DR and AMD. Current anti‐VEGF injections, while effective, require invasive, frequent administration. Pene/LQ015, is developed a novel topical anti‐VEGFA nanobody formulation achieving therapeutic intraocular levels through penetratin analog‐enhanced delivery.
