Abstract: The present invention provides methods of producing thrombin using coordinated coexpression systems, and particularly inducible coexpression systems, capable of controlled induction of expression of each gene product required for the production of thrombin.

Abstract: Novel binding molecules, comprising humanized antibodies, fragments, variants, and derivatives thereof, compositions, methods, and kits comprising the same, are described, wherein the binding molecules specifically bind to FXI and FXIa. The binding molecules are capable of binding to and forming an immune complex with the factor XI A2 domain, and thereby disrupting the contact activation molecular complex without affecting hemostatic factor XI activity or activation. The binding molecule of this disclosure is useful in safely inhibiting thrombosis and inflammation without compromising hemostasis. The binding molecules, compositions, methods, and kits provided herein are therefore intended to treat, inter alia, thrombosis- and inflammation-related diseases and conditions. Moreover, polynucleotides encoding the binding molecules of this disclosure, vectors comprising the polynucleotides, and host cells for producing the polynucleotides are provided.

Abstract: Monoclonal antibodies that bind, such as specifically bind, blood protein factor XII (FXII) are described. The monoclonal antibodies (including antigen-binding fragments thereof) are capable of forming immune complexes with human FXII and inhibiting FXII activity, resulting in safe anti-inflammatory and anti-thrombotic effects.

Abstract: Provided herein are methods, compounds, and compositions for safely reducing thrombopoietin in a cell or an individual. Such methods, compounds, and compositions maintain platelet count within a safe hemostatic range. Such methods, compounds, and compositions are useful to safely treat, prevent, or ameliorate a disease that can benefit from platelet count reduction in an individual. Such methods, compounds, and compositions are useful for treating or preventing diseases in which thrombopoietin contributes to the presence or activation of platelets contributes to and promotes disease initiation or progression, and/or adversely affects disease outcome.

Abstract: Compositions and methods for inhibiting thrombosis without compromising hemostasis are described. Compositions include anti-factor XI monoclonal antibodies (aXIMabs) capable of binding to an epitope on the heavy chain of human FXI, particularly the A3 domain of the heavy chain of human FXI. Compositions also include epitope-binding fragments, variants, and derivatives of the monoclonal antibodies, cell lines producing these antibody compositions, and isolated nucleic acid molecules encoding the amino acid sequences of the antibodies. The disclosure further includes pharmaceutical compositions comprising the disclosed anti-factor XI monoclonal antibodies, or epitope-binding fragments, variants, or derivatives thereof, in a pharmaceutically acceptable carrier.

Abstract: Disclosed herein are monoclonal antibodies specific for factor XI (fXI) that prevent activation of fXI by factor XIIa (fXIIa). The monoclonal antibodies are universal fXI antibodies, capable of binding all mammalian species tested. The anti-fXI monoclonal antibodies prolong clotting time in mammalian plasmas. Moreover, administration of the fXI monoclonal antibodies disclosed herein results in inhibition of thrombosis without altering hemostasis in animal models of thrombosis. Thus, provided herein are monoclonal antibodies specific for fXI that block activation of fXI by fXIIa, compositions and immunoconjugates comprising such antibodies and their methods of use.

Abstract: Provided are antibodies that selectively bind to and inhibit activation of coagulation factor XII. Methods of treatment employing these antibodies are described herein.
