Abstract
To this day, use of oily eye drops and non-invasive retinal delivery remains a major challenge. Oily eye drops usually cause ocular irritation and interfere with normal function of the eye, while ocular injections for retinal drug delivery cause significant adverse effects and a high burden on the healthcare system. Here the authors report a novel topical Non-Invasive Ocular Delivery Platform (NIODP) through the periorbital skin for high efficiency anterior and posterior ocular delivery in a non-human primate model (NHP). A single dose of about 7mg JV-MD2 (omega-3 DHA) via the NIODP reached the retina at Cmax of 111µg/g and the cornea at Cmax of 66µg/g. NIODP also delivered JV-DE1, an anti-inflammatory agent in development for dry eye diseases, as efficiently as eye drops did to anterior segments of NHP. The topical NIODP seems to transport drug candidates through the cornea pathway to the anterior and via the conjunctiva/sclera pathway to the posterior segments of the eye. The novel NIODP method has the potential to reshape the landscape of ocular drug delivery, especially for oily eye drops and retinal delivery, where the success of treatment lies in the ocular tolerability and bioavailability of drugs in the target tissue.
