The present invention relates to the therapeutic application of the Kazal-type serine protease inhibitor Infestin or domains thereof or modified Kazal-type serine protease inhibitors based on Infestin homologs, which prevent the formation and/or stabilization of three-dimensional arterial or venous thrombi by interfering with proteins involved in activation of the so-called intrinsic coagulation pathway. The present invention also relates to the use of Kazal-type serine protease inhibitors or fragments thereof or modified Kazal-type serine protease inhibitors in the treatment or prophylaxis of a condition or disorder related to arterial thrombus formation, i.e. stroke or myocardial infarction, inflammation, complement activation, fibrinolysis, angiogenesis and/or diseases linked to pathological kinin formation such as hypotonic shock, edema including hereditary angioedema, bacterial infections, arthritis, pancreatitis, or articular gout, Disseminated Intravasal Coagulation (DIC) and sepsis.
A polypeptide comprising Infestin-4 or an Infestin-4 fragment with 1 to 10 amino acids deleted from the N- or C-terminus, wherein the Infestin-4 or Infestin-4 fragment is linked to at least one half-life enhancing polypeptide, and wherein the polypeptide inhibits Factor XIIa and prolongs clotting time in an aPTT assay.
A method for increasing the half-life of Infestin-4 or of an Infestin-4 fragment in vivo comprising linking a polypeptide comprising Infestin-4 or an Infestin-4 fragment with 1 to 10 amino acids deleted from the N- or C-terminus to at least one half-life enhancing polypeptide.
