Light-activated carriers for the controlled delivery of therapeutic peptides in posterior segment eye diseases

Descrizione del progetto

Nanovettori attivati da impulsi luminosi per il rilascio di farmaci nell’occhio

La degenerazione maculare e il glaucoma sono malattie dell’occhio connesse all’età che, secondo le attese, diventeranno maggiormente prevalenti nel futuro, a causa dell’aumento della popolazione anziana. Poiché tali patologie compromettono la vista e, di conseguenza, la qualità della vita, vi è la necessità di somministrare terapie efficienti. L’obiettivo principale del progetto Light4Sight, finanziato dall’UE, è sviluppare un sistema di somministrazione dei farmaci basato su nanotecnologia contenente peptidi terapeutici in un idrogel sensibile alla luce. L’idrogel può essere iniettato nell’umor vitreo, la sostanza gelatinosa e trasparente che occupa lo spazio tra il cristallino e la retina. Il rilascio dei farmaci sarà attivato dalla luce visibile in maniera controllata, evitando la tossicità ma aumentando il tempo di dimezzamento dell’agente terapeutico.

Obiettivo

In 2016, the global sales of biopharmaceutical drugs (protein, peptides) in ophthalmic applications exceeded $8 billion and is estimated to increase to $35.7 billion by 2025. The growth of the ophthalmic drug market is primarily driven by an increasing aged population suffering from age- and lifestyle-related diseases such as macular degeneration, diabetic retinopathy, glaucoma, among others. These diseases cause moderate or complete vision loss, resulting in significant reduction in quality of life. Consequently, innovative approaches for the effective delivery of biopharmaceuticals for the treatment of chronic intraocular diseases are required.
Currently, intravitreal injection of drugs is the most acceptable and effective method to treat vitreoretinal diseases. By placing the drug in the posterior eye, it evades the ocular barriers common in topical and systemic delivery, allowing higher drug doses to reach the target site. However, treatments require frequent injections to maintain adequate intraocular concentration, which are invasive, increase the risk of adverse effects and pose significant treatment burden on patients and healthcare providers. Thus, alternative ways to deliver these drugs that require less frequent administration need to be developed. Light4Sight aims to develop a novel delivery platform consisting of self-assembling nanocarriers incorporating therapeutic peptides and suspended within a light-sensitive supramolecular hydrogel. The hydrogel can be injected in the vitreous and release of nanocarriers be activated through the irradiation of visible light. This approach provides several benefits: 1) minimizes the use of repeated injections reducing treatment burden; 2) reduces burst release of the nanocarriers avoiding potential dose related toxicity; 3) on-demand release to match patient needs; 4) allows high drug loading for long-term therapy; 5) protects peptide drugs from rapid clearance in the vitreous increasing their half-life.
