ModeRN Approach to ocular disease treatment - Smart lipid-based nanoparticle systems for the delivery of mRNA to the ocular tissues

Projektbeschreibung

Nanopartikel für die effiziente Arzneimittelabgabe im Auge

Die Behandlung von Augenerkrankung beruht meist auf Arzneimitteln mit kleinen Molekülen und Proteinen, die jedoch durch eine geringe Absorption behindert werden. Ziel des über die Marie-Skłodowska-Curie-Maßnahmen finanzierten Projekts LIPOmRNA ist die Entwicklung von lipidbasierten Nanopartikeln, die therapeutische mRNA-Moleküle in die Hornhaut und die Netzhaut einbringen. Die Forschenden werden sich mit anatomischen Barrieren befassen und die Technologie für die Abgabe am Auge optimieren, indem sie die lipidbasierten Nanopartikel mit pH-sensitiven Merkmalen und augenspezifischen Oberflächeneigenschaften versehen. Die Verabreichung von lipidbasierten Nanopartikeln erfolgt durch mukoadhäsive Augentropfen und intravitreale Injektionen, um die Retention und Permeation zu verbessern. Die Projektergebnisse werden die vielversprechende mRNA-Technologie für die Behandlung von Augenerkrankungen fördern.

Ziel

Many severe ocular diseases lead to visual impairment and blindness in millions of patients worldwide, and the number is rapidly growing in aging populations. Most ocular diseases are still without drug treatment and the current treatments are based on the use of small molecules and protein drugs. However, poor ocular absorption and rapid elimination restrict their development and use in ophthalmology.
Technology for mRNA transfer into the cornea and retina and subsequent expression of encoded proteins may open widely applicable possibilities for the treatment of ocular diseases (e.g. various retinal degenerations, uveitis) as topical eye drops or intravitreal injections. However, clinical application of mRNAs is limited by their poor in vivo stability and low cellular entry. Therefore, efficient and safe delivery systems for ocular mRNA transfer are urgently needed.
Our research program aims to develop lipid-based nanoparticle (LNP) systems that are specifically tailored for mRNA delivery into the corneal, conjunctival and retinal cells. The project will address the critical anatomical and physiological barriers of ocular mRNA delivery topically and intravitreally. Chemical structure and composition of LNPs will be carefully modified to optimize mRNA delivery across ocular barriers. Smart pH-sensitive LNPs with eye specific surface moieties will be used to target ocular cells and trigger mRNA release and cytosolic delivery. Moreover, eye drop formulations will be mucoadhesive, increasing precorneal residence time, whereas intravitreal injectables will be capable of permeating in the vitreous and inner limiting membrane into the retinal cells. The representative in vitro and ex vivo test models will be used to select the most promising LNPs for versatile animal experiments. Finally, in vivo pharmacokinetics and mRNA mediated anti-VEGF responses of the delivery systems will be investigated to understand their translational potential towards clinical use.
