Abstract: This patent document relates to antibodies, antigen-binding antibody fragments (Fabs), and other protein scaffolds, directed against human antithrombin ? complexed with heparin and/or heparin-like structure (AT?H). These AT?H binding proteins can block the anti-coagulant activity of AT? to induce coagulation. Therapeutic uses of these antibodies and binders are described herein as are methods of panning and screening specific antibodies.

Abstract: Isolated monoclonal antibodies that bind human tissue factor pathway inhibitor (TFPI) and the isolated nucleic acid molecules encoding them are provided. Pharmaceutical compositions comprising the anti-TFPI monoclonal antibodies and methods of treating deficiencies or defects in coagulation by administration of the antibodies are also provided. Methods of producing the antibodies are also provided.

Abstract: Antibodies are disclosed that bind to and inhibit the anti-coagulant function of TFPI and have a lower affinity for TFPi at pH 6.0 than at pH 7.4. The lower affinity at pH 6 improves circulating half-life (T1/2) due to reduced target mediated clearance, a process by which an antibody/antigen complex, is endocytased and trafficked to the lysosome where both components are degraded. The lower affinity at pH 6.0 results in disruption of the complex prior to lysosome targeting and allows for re-circulation of the antibody. Specific modifications to antibody binding by histidine residue substitution are disclosed along with methods of use.

Abstract: This invention relates to Factor VIII muteins that are covalently bound, at a predefined site that is not an N-terminal amine, to one or more biocompatible polymers such as polyethylene glycol. The mutein conjugates retain FVIII procoagulant activity and have improved pharmacokinetic properties.

Abstract: Antibodies are disclosed that bind to and inhibit the anti-coagulant function of TFPI and have a lower affinity for TFPI at pH 6.0 than at pH 7.4. The lower affinity at pH 6 improves circulating half-life (T½) due to reduced target mediated clearance, a process by which an antibody/antigen complex is endocytosed and trafficked to the lysosome where both components are degraded. The lower affinity at pH 6.0 results in disruption of the complex prior to lysosome targeting and allows for re-circulation of the antibody. Specific modifications to antibody binding by histidine residue substitution are disclosed along with methods of use.

Abstract: Provided herein are antibodies, antigen-binding antibody fragments (Fabs), and other protein scaffolds, directed against human activated Protein C (aPC) with minimal binding to its zymogen Protein C (PC). Moreover, these aPC binding proteins could potentially block the anti-coagulant activity of aPC to induce coagulation. Therapeutic uses of these binders are described herein as are methods of panning and screening specific antibodies.

Abstract: The invention is directed to a procoagulant conjugate having an endopeptidase-activatable procoagulant protein moiety and one or more bioprotective moieties, which are conjugated to one another by a linker that is cleaved by an endopeptidase in situ to release the bioprotective moiety. The invention is also directed to therapeutic uses of the procoagulant conjugate and methods of making the conjugate.
