  • Patent number: 7615217
    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.

  • Publication number: 20090088561
    Abstract: Disclosed are methods for the genetic construction and expression of antibody-based fusion proteins with enhanced circulating half-lives. The fusion proteins of the present invention lack the ability to bind to immunoglobulin Fc receptors, either as a consequence of the antibody isotype used for fusion protein construction, or through directed mutagenesis of antibody isotypes that normally bind Fc receptors. The fusion proteins of the present invention may also contain a functional domain capable of binding an immunoglobulin protection receptor.

  • Publication number: 20080025947
    Abstract: Methods directed to enhancing the effectiveness of IL-2 in stimulating the immune system is disclosed. According to one method, an antagonist directed against the CD25 subunit of the high-affinity IL-2 receptor complex is administered in conjunction with IL-2. The CD25 antagonist may be an anti-CD25 antibody. According to another method, an anti-IL-2 antibody is administered in conjunction with IL-2. In another method, a mutant IL-2 with diminished ability to bind the CD25 subunit of the high-affinity IL-2 receptor complex is administered. In another method, an CD4 antagonist is administered in conjunction with IL-2 in order to stimulate the immune system.
