  • Patent number: 8454582
    Abstract: Featured is a method for instilling one or more bioactive agents into ocular tissue within an eye of a patient for the treatment of an ocular condition, the method comprising concurrently using at least two of the following bioactive agent delivery methods (A)-(C): (A) implanting a sustained release delivery device comprising one or more bioactive agents in a posterior region of the eye so that it delivers the one or more bioactive agents into the vitreous humor of the eye; (B) instilling (e.g., injecting or implanting) one or more bioactive agents subretinally; and (C) instilling (e.g., injecting or delivering by ocular iontophoresis) one or more bioactive agents into the vitreous humor of the eye.

  • Patent number: 8034369
    Abstract: The invention provides a controlled release bioactive agent delivery device for treatment of an eye that includes a body member having a direction of extension, a longitudinal axis along the direction of extension, and a proximal end and a distal end, wherein at least a portion of the body member deviates from the direction of extension, and a polymeric coated composition in contact with a surface of the body member, the polymeric coated composition including a first polymer, a second polymer, and a bioactive agent. The first polymer and the second polymer are hydrophobic, and the body member has a length such that, upon placement of the device at an implantation site within a posterior segment of an eye, the device does not enter a central visual field of the eye. The invention also provides methods method of delivering bioactive agent to a posterior region of an eye.

  • Patent number: 7247714
    Abstract: This invention is in the area of regulatory DNA sequences and their methods of use. Specifically, DNA sequences found in the regulatory region of cytoprotective genes are described that are termed cytoprotective response elements. DNA constructs also are provided that include cytoprotective response elements operably linked to heterologous protein coding sequence, as well as cells and non-human organisms that include the cytoprotective response elements optionally operably linked to a heterologous protein coding sequence, and a method for screening for a compound that increases mRNA or protein regulated by a cytoprotective response element. It has been discovered that the cytoprotective response elements mediate the coordinate activation of certain genes that protect cells from damaging effects of oxidative stress, and that they do so, for example during conditions of hemodynamic shear stress.
