The Kunitz Protease Inhibitor (KPI) domain of protease nexin 2 (PN2) potently inhibits coagulation factor XIa. Recombinant KPI has been shown to inhibit thrombosis in mouse models, but its clearance from the murine circulation remains uncharacterized. The present study explored the pharmacokinetic and pharmacodynamic effects of fusing KPI to human serum albumin (HSA) in fusion protein KPIHSA.
