Abstract: The application discloses methods and compositions for inhibiting functions associated with vascular endothelial growth factor-A (VEGF-A). The methods and compositions may involve the use of pan-variant specific aptamers for binding to VEGF-A, and preventing or reducing association of VEGF-A with Flt-1, KDR, or Nrp-1. The methods and compositions may include one or more aptamers that bind to receptor binding face of VEGF-A. The methods and compositions may include one or more aptamers that bind to a receptor binding domain of VEGF-A. The application further provides anti-VEGF-A aptamers for the treatment of ocular diseases or disorders. In some cases, the anti-VEGF-A aptamers may have a stem-loop secondary structure.

Abstract: The application discloses methods and compositions for inhibiting functions associated with Interleukin-8 (IL8). The methods and compositions may involve the use of aptamers for binding to IL8 and preventing or reducing association of IL8 with CXCR1, CXCR2, or both. The methods and compositions may include one or more aptamers that bind to an N-terminal domain of IL8. The methods and compositions may include one or more aptamers that bind to a hydrophobic pocket of IL8. The methods and compositions may include one or more aptamers that bind to an N-loop of IL8. The methods and compositions may include one or more aptamers that bind to a GAG binding site of IL8. The application further provides anti-IL8 aptamers for the treatment of ocular diseases or disorders. In some cases, the anti-IL8 aptamers may have a stem-loop secondary structure.

Abstract: Methods are provided herein for generating and selecting aptamers. The aptamers can be suitable as therapeutic aptamers for the treatment of a disease or disorder. The methods provided may improve the efficiency and/or effectiveness of generating a therapeutic aptamer over traditional methods. The methods may generally involve selective pressure including competitive elution to generate aptamers that specifically bind to therapeutically-relevant epitopes and have a desired mechanism of action.

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.
