Abstract

The catalytic active site of Factor VII is modified to produce a compound which effectively interrupts the blood coagulation cascade. The modifications render Factor VIIa substantially unable to activate plasma Factors X or IX. Pharmaceutical compositions of the modified Factor VII are used to treat a variety of coagulation-related disorders, including platelet deposition, vascular thrombosis, ischemic reperfusion, acute closure of a coronary artery, vascular restenosis secondary to balloon angioplasty, endarterectomy, reductive atherectomy, stent placement, laser therapy or rotablation.
