The polymer-drug conjugates can form nanoparticles, microparticles, and implants that are capable of effectively delivering therapeutic levels of one or more active agents for an extended period of time. Administration to the eye of an active agent in the form of a non-linear multiblock copolymer-drug conjugate produces decreased side effects when compared to administration of the active agent alone. Also provided are methods of treating intraocular neovascular diseases, such as wet age-related macular degeneration as well as diseases and disorders of the eye associated with inflammation, such as uveitis.

  • Patent number: 10076496
    Abstract: The present invention provides organic nanoparticles that include a molecule having a Log P value of about 3 or above, an amphiphilic diblock copolymer or a surfactant, and a pharmaceutically-acceptable hydrophilic polymer. The present invention also provides methods of making these nanoparticles, e.g., by flash nanoprecipitation, with control over particle size and surface properties. The methods of the present invention provide a means for co-precipitating a water-insoluble compound with an amphiphilic stabilizer within a few milliseconds. The nanoparticles of the present invention exhibit high drug loading, e.g., 50% w/w, and can be produced with a mean particle size less than 200 nm and with a narrow particle size distribution.

  • Patent number: 10064819
    Abstract: Devices, systems, and methods for delivery of an active agent into the eye of a subject can include an intraocular active agent delivery device including an active agent dispersed within a biodegradable active agent matrix. The active agent includes dexamethasone and the delivery device is adapted to fit within a lens capsule or ciliary sulcus of an eye. The delivery device can be inserted into the lens capsule or ciliary sulcus of an eye during cataract surgery or for treatment of uveitis.

  • Patent number: 9919052
    Abstract: Polyurethane microparticles are derived from structural units comprising poly(alkylene oxide) moieties, caprolactone moieties and urethane moieties. The microparticles may include an active agent and have a particle size from 0.1 to 100 microns. Microparticles for injection have a particle size of 15 to 80 microns; for use as a aerosol 1 to 3 microns; and for intraocular use 0.02 to 2 microns. Dispersivity is in the range 1 to 3.

  • Patent number: 9885808
    Abstract: Coating with photochromic properties, method for producing said coating and use thereof applicable to optical articles and glazed surfaces. The coating is formed by the combination of the following three elements: (1) a polymeric matrix, which is typically rigid and deposited on the surface of interest; (2) hollow, sealed micro- and/or nanocapsules dispersed within said matrix; and (3) solutions of photochromic compounds (chosen from a group comprising spirooxazine, azobenzenes or chromenes) in a liquid solvent that does not react (with the photochromic compound and with the capsule wall), which are encapsulated inside said micro- or nanocapsules.
