Nucleic acids encoding those polypeptides are also disclosed. Methods for identifying an agent having anti-coagulation activity are also disclosed. These methods comprise determining whether the agent displaces the polypeptide or derivative from its factor VIIa binding site. The agent identified in these methods is also useful in methods for treating a patient to prevent thrombosis. The treatment methods comprise administration of the agent to the patient. Additional methods are also disclosed for treating a patient to prevent thrombosis, comprising treating the patient with a polypeptide or derivative comprising the factor VIIIa binding site on factor IXa. Methods of preventing coagulation in a blood sample are also disclosed, comprising adding the polypeptides or derivatives described above to the blood sample. Methods of detecting factor VIIIa in a sample are also disclosed. Those methods comprise contacting the sample with the above-described polypeptide or derivative, wherein the polypeptide or derivative also comprises a covalently attached detectable moiety, then determining whether the polypeptide or derivative is binding factor VIIIa from the sample.

The present invention relates to novel polypeptide variants of factor VII (FVII) or factor VIIa (FVIIa) polypeptides, where said variants comprise an amino acid substitution in position 10 and 32 and where said variants further comprise a sugar moiety covalently attached to an introduced in vivo N-glycosylation site located outside the Gla domain. Such polypeptide variants are useful in therapy, in particular for the treatment of a variety of coagulation-related disorders, such as trauma.

The present invention relates to a proteinaceous construct comprising plasmatic or recombinant factor VIIa (FVIIa) or biologically active derivatives thereof, which are bound to a carbohydrate moiety comprising 1-4 sialic acid units, wherein the in vivo half-life of the proteinaceous construct is substantially prolonged in the blood of a mammal, as compared to the in vivo half-life of a FVIIa molecule not bound to a carbohydrate moiety. The invention also provides a method for controlling bleeding in a mammal having a bleeding disorder due to functional defects or deficiencies of FVIIa, FVIII, or FIX. The invention also provides a method for controlling bleeding in a mammal during surgery or trauma.

The present invention relates to a novel pharmaceutical combination for treating thromboembolic and/or inflammatory diseases, wherein the combination has: (a) a first therapeutic agent independently selected from the group consisting of a selective Factor VIIa inhibitor, a selective Factor XIa inhibitor, a combination of the selective Factor VIIa and XIa inhibitors, or pharmaceutically acceptable salt forms thereof; and (b) a second therapeutic agent comprising a selective plasma kallikrein inhibitor or a pharmaceutically acceptable salt form thereof.
