Abstract

DESCRIPTION (provided by applicant): This project seeks to treat age related macular degeneration (AMD) by creating a platform for the sustained intra-ocular delivery of antibody-based therapeutic agents to inhibit vascular endothelial growth factor (VEGF). This interdisciplinary team will design and manufacture prototype nanoporous thin-film devices; establish drug loading techniques and drug release properties; and complete pre-clinical biocompatibility and functional testing in vitro and in animal eye models. Unlike other sustained release technologies, the proposed thin-film devices are functionally tunable to achieve zero-order drug release kinetics, attaining a flat drug release profile and a tight concentration range over several months. By sequestering drug in an underlying reservoir layer within the device, the drug can be protected from the external microenvironment. This ability to load and protect the drug is key for biologically-based therapies which often undergo rapid degradation and clearance from the eye. The device design proposed in this program will mitigate many challenges inherent in ocular drug delivery and provide an innovative approach to the delivery of ocular therapeutics.
