Use for treating cancer or pathological angiogenesis in a patient.
Abstract: Described are polypeptide dimers comprising two soluble gp130 molecules wherein each of said molecules is fused to an Fc domain of an IgG1 protein and wherein the hinge region of the Fc domain is modified resulting in advantageous properties of the dimer. In a particularly preferred embodiment, the hinge region comprises the amino acid sequence motif Ala234-Glu235-Gly236-Ala237. Moreover, a pharmaceutical composition containing said dimer and various medical uses are described.
Abstract: Disclosed is an isolated antigen binding protein, such as but not limited to, an antibody or antibody fragment. Also disclosed are pharmaceutical compositions and medicaments comprising the antigen binding protein, isolated nucleic acid encoding it, vectors, host cells, and hybridomas useful in methods of making it. In some embodiments the antigen binding protein comprises one to twenty-four pharmacologically active chemical moieties conjugated thereto, such as a pharmacologically active polypeptide.

Abstract: The present application discloses methods for treating an IL-6-mediated disorder such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), systemic JIA (sJIA), polyarticular course JIA (pcJIA), systemic sclerosis, or giant cell arteritis (GCA), with subcutaneously administered antibody that binds interleukin-6 receptor (anti-IL-6R antibody). In particular, it relates to identification of a fixed dose of anti-IL-6R antibody, e.g. tocilizumab, which is safe and effective for subcutaneous administration in patients with IL-6-mediated disorders. In addition, formulations and devices useful for subcutaneous administration of an anti-IL-6R antibody are disclosed.
Abstract: The present invention provides an antibody to human IL-3R? chain, which does not inhibit IL-3 signaling and binds to B domain of the human IL-3R? chain but does not bind to C domain of the human IL-3R? chain; a composition for preventing or treating a blood tumor in which a cell expressing IL-3R? is found in bone marrow or peripheral blood of a subject, which comprises the antibody to human IL-3R? as an active ingredient; and a method for treating a blood tumor in which a cell expressing IL-3R? is found in bone marrow or peripheral blood, which comprises administering, to a subject, a composition comprising the IL-3R? antibody as an active ingredient.
Abstract: An objective of the present invention is to provide novel therapeutic agents for cancer, which have an excellent antitumor effect in cancer patients by enhancing their immune function. The present inventors discovered that the administration of at IL-6 inhibitor and/or gemcitabine or a salt thereof to tumor-bearing organisms yields an excellent antitumor T cell response-enhancing effect, and completed the present invention. In addition, the present inventors discovered that the T cell response-enhancing effect produces an excellent antitumor effect.
