Abstract: This invention relates to the fields of immunology and protein therapeutics. The therapeutic proteins are polypeptides to be administered especially to humans. The polypeptides are modified whereby the modification results in a reduced propensity for the polypeptide to elicit an immune response upon administration to the human subject. The invention therefor provides methods for the development of therapeutic polypeptides that are less immunogenic than any non-modified counterpart when used in vivo. The modifications used according to this invention relate, for example, to the introduction of protease cleavage sites, attachment of different molecules or insertion of non-natural amino acids.

Abstract: This invention pertains to a TNF alpha-binding polypeptide composition comprising at least one of a modified heavy chain variable region polypeptide or a modified light chain variable region polypeptide that is capable of specifically binding to human TNF alpha. The modified heavy and light chain variable region polypeptides of the TNF alpha binding polypeptide are modified by at least one amino acid residue substitution, deletion or addition and are homologous to the heavy and light chain variable regions, respectively, of a non-human monoclonal antibody that specifically binds human TNF alpha. The polypeptide compositions of the invention comprising modified heavy and light chain variable region polypeptides are less immunogenic in a human than are the homologous heavy and light chain variable region polypeptides from a non-human animal.

Abstract: The present invention relates a modified human interferon beta (INF?) which is less immunogenic than human INF? (SEQ ID NO: 1) when administered in vivo to a human. The modified human INF? comprises an amino acid residue sequence that differs from SEQ ID NO: 1 by an amino acid residue substitution selected from the group consisting of L57A, L57C, L57D L57E, L57G, L57H, L57K, L57N, L57P, L57Q, L57R, L57S, and L57T and an additional substitution selected from the group consisting of the H140A, H140C, H140G, and H140P.

Abstract: The invention relates to artificial modified proteins, preferably fusion proteins, having a reduced immunogenicity compared to the parent non-modified molecule when exposed to a species in vivo. The invention relates, above all, to novel immunoglobulin fusion proteins which essentially consist of an immunoglobulin molecule or a fragment thereof covalently fused via its C-terminus to the N-terminus of a biologically active non-immunoglobulin molecule, preferably a polypeptide or protein or a biologically active fragment thereof. In a specific embodiment, the invention relates to fusion proteins consisting of an Fc portion of an antibody which is fused as mentioned to the non-immunological target molecule which elicits biological or pharmacological efficacy. The molecules of the invention have amino acid sequences which are altered in one or more amino acid residue positions but have in principal the same biological activity as compared with the non-altered molecules.
