Abstract
The present invention relates to recombinant fusion proteins wherein erythropoietin (EPO) is linked via its C-terminus to an Fc fragment, and wherein the recombinant fusion proteins are further carbamoylated at the primary amines of the fusion protein. More specifically the invention relates to carbamoylated EPO-Fc fusion proteins, wherein at least one, preferably two or more, lysine amine residues and/or the N-terminal amino acid of the fusion protein are carbamoylated. The carbamoylated EPO-Fc fusion proteins of the present invention having a reduced hematopoietic activity whereas the tissue regenerative activity, i.e. the nerve cell regenerative activity remains unaltered or is even enhanced as compared to unmodified EPO-Fc fusion proteins. The invention further relates to a process for the manufacture of such fusion proteins and to pharmaceutical compositions containing them, as well as to the use of such fusion proteins and pharmaceutical compositions for medical therapy.
