Zusammenfassung:The present invention provides a modified polypeptide which binds Factor VIII. The modified polypeptide comprises a sequence as shown in SEQ ID NO:3 in which the sequence comprises at least one modification at a position selected from the group consisting of L18, V42, K149, N248, S279, V320, T325, Q395 and K418 such that the modified polypeptide binds to Factor VIII with an off rate lower than a reference polypeptide comprising an unmodified SEQ ID NO:3.
