Summary: | The present invention relates to a recombinant Factor VIII protein comprising, in a single chain, a heavy chain portion comprising an A1 and an A2 domain and a light chain portion comprising an A3, C1 and C2 domain of Factor VIII, wherein the B-domain is partially deleted in two deletions, the first leading to the presence of a defined processing sequence cleavable by thrombin, and the second leading to absence of the furin cleavage recognition site at position R1664-R1667. An internal fragment of the B-domain is maintained Nucleic acids encoding said protein, host cells and methods of preparing the protein are also provided, as well as a pharmaceutical composition comprising the protein, nucleic acid or host cell, which may be used for treatment of hemophilia A. |
