    Abstract: The present invention provides chimeric proteins comprising a Factor VIII (FVIII) polypeptide and XTEN polypeptides. The FVIII polypeptide can have a reduced affinity for von Willebrand Factor (VWF). XTEN polypeptides of appropriate sizes are inserted into the FVIII polypeptide at particular locations in order to extend the half-life of the FVIII polypeptide. The invention also includes nucleotides, vectors, host cells, and methods of using the chimeric proteins, e.g., to treat bleeding diseases and disorders.

    Abstract: The present invention provides a chimeric molecule comprising a VWF protein fused to a heterologous moiety via a VWF linker. The invention provides an efficient VWF linker that can be cleaved in the presence of thrombin. The chimeric molecule can further comprise a polypeptide chain comprising a FVIII protein and a second heterologous moiety, wherein the chain comprising the VWF protein and the chain comprising the FVIII protein are associated with each other. The invention also includes nucleotides, vectors, host cells, methods of using the chimeric proteins.
