  • Patent number: 8865868
    Abstract: The invention relates to conjugated proteins, in particular but not exclusively, blood coagulation factors, to processes for preparing the conjugated proteins which contain the steps of reacting a protein or glycoprotein, such as factor VIIa or human growth hormone, with a water insoluble albumin binder in the presence of an optionally substituted cyclodextrin molecule, to pharmaceutical compositions comprising the protein conjugates and to the use of the protein conjugates in therapy, in particular but not exclusively, for the treatment of diseases alleviated by blood coagulation factors such as the prophylactic treatment of hemophilia.

  • Patent number: 8859731
    Abstract: A method of selectively introducing a substituent into a protein proximal to a binding site on the protein for a homing peptide, comprising: (a) contacting the protein with a compound comprising a homing peptide having the ability to bind to the binding site of the protein; and (b) allowing a moiety on the protein proximal to the binding site to react with the compound comprising the homing peptide, thereby to transfer the substituent G onto the protein.

  • Publication number: 20140295521
    Abstract: A new use of a molecule comprising at least one moiety which is a biologically active protein and at least one moiety capable of binding to a serum albumin of a mammal is provided, for preparation of a medicament which elicits no or a reduced immune response upon administration to the mammal, as compared to the immune response elicited upon administration to the mammal of the biologically active protein per se. Also provided is a method of reducing or eliminating the immune response elicited upon administration of a biologically active protein to a human or non-human mammal, which comprises coupling the polypeptide to at least one moiety capable of binding to a serum albumin of the mammal.

  • Patent number: 8835388
    Abstract: The present invention relates to a proteinaceous construct (also designated as polymer-VWF-conjugate) comprising plasmatic and/or recombinant von Willebrand factor (VWF), said VWF being bound to at least one physiologically acceptable polymer molecule, as well as to a complex between said proteinaceous construct and at least one factor VIII (FVIII) protein. The physiologically acceptable polymer molecule can be, for instance, polyethylene glycol (PEG) or polysialic acid (PSA). Further the present invention relates to methods for prolonging the in vivo-half-life of VWF or FVIII in the blood of a mammal having a bleeding disorder associated with functional defects of or deficiencies of at least one of FVIII or VWF.
