  • Publication number: 20230126447
    Abstract: This disclosure provides an ocular tissue depot of a selected complement factor D (CFD) inhibitor for the extended treatment of an ocular disorder mediated by complement factor D. In particular, the disclosure includes the creation of a drug depot within the choroid-retina pigmented epithelium (C-RPE) and/or the iris-ciliary body (I-CB) of the eye by means of the systemic (oral or parenteral) administration of the compound, where the compound accumulates in ocular tissue and is released over an extended period for the treatment of a posterior and/or anterior eye disorder.

  • Publication number: 20150344533
    Abstract: The present invention relates, in general, to a pharmacologic system to modulate the biology of platelets based upon a nucleic acid ligand that can interact with and modulate the activity of platelet glycoprotein GPVI to regulate platelet function. These nucleic acid ligands are also actively reversible using a modulator that inhibits the activity of the nucleic acid ligand to neutralize this pharmacologic effect and thereby restore GPVI function, including collagen binding, platelet adhesion, collagen-induced platelet activation, and collagen-induced platelet aggregation. The invention further relates to compositions comprising the nucleic acid ligand, the ligand and a modulator, methods to generate the nucleic acid ligand and its modulator, as well as methods of using these agents and compositions in medical therapeutic and diagnostic procedures.
