Stabilized protein or peptide conjugates able to bond albumin having extended biological half-lives

摘要

A process for extending the half-life in vivo by a biologically active protein or peptide, characterized by covalently coupling said protein or peptide to a polypeptide fragment capable of binding to a serum protein, whereby when administering the resulting protein or peptide conjugate its binding to the serum protein results in extended biological activity, the use of the protein or peptide conjugate above for manufacturing a medicament which, when administered to a mammal including man, shows extended half-life in vivo; and a method of therapeutic or prophylactic treatment.
