  • Patent number: 11730703
    Abstract: The present invention concerns nanoparticles useful for treating posterior segment ocular diseases or conditions, such as macular degeneration and diabetic retinopathy; compositions comprising the nanoparticles; methods for producing the nanoparticles; and methods for treating posterior segment ocular diseases or conditions, comprising administering the nanoparticles or compositions to the ocular posterior segment of an afflicted eye.
    Type: Grant
    Filed: December 27, 2021
    Date of Patent: August 22, 2023
    Assignee: UNIVERSITY OF SOUTH FLORIDA
    Inventors: Kathleen Emily-Ann Halasz, Yashwant V. Pathak, Vijaykumar Bhadabhai Sutariya

  • Patent number: 10973776
    Abstract: The present invention provides a sustained drug delivery system for the treatment of age-related macular degeneration (AMD), comprising corticosteroid encapsulated nanoparticles incorporated into a thermoreversible hydrogel. The corticosteroid may be triamcinolone acetate (TA), dexamethasone, or loteprednol etabonate (LE). The proposed drug delivery system is nontoxic to ARPE-19 (retinal pigment epithelium) cells and significantly reduces VEGF (vascular endothelial growth factor) expression as compared to solutions of the coticosteroids. The present invention provides sustained delivery of the corticosteroid to the posterior segment of the eye, reducing the frequency of intraocular injections necessary to maintain therapeutic concentrations.
