Abstract:
PROBLEM TO BE SOLVED: To provide a new compound which binds to a human erbB2 gene product (ErbB2, also referred to as HER2, or c-ErbB-2); and to provide a pharmaceutical composition comprising the new compound. SOLUTION: The compound comprises a non-naturally occurring amino acid sequence which binds to the ErbB2. The compound comprises a peptide ligand composed of the non-naturally occurring amino acid sequence of about 5-50 amino acid residues, wherein the peptide ligand comprises a CH3 domain, and a hinge region as an immunoglobulin constant region sequence.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for inhibiting or preventing growth of cancer cells. SOLUTION: A VEGF-E (vascular endothelial growth factor-E) antagonist which is a new polypeptide related to VEGF (vascular endothelial growth factor) and bone morphogenetic protein 1 is administered in combination with a second agent. Furthermore, the second agent is a chemotherapeutic agent, a growth inhibitory agent, a cytotoxic agent, an angiostatic agent, an agent used in radiation therapy, an anti-VEGF antibody, an FGF antagonist, a PDGF antagonist, or an antibody that binds to an ErbB2, an EGFR, an ErbB3, an ErbB4 or a VEGF receptor. In addition, the chemotherapeutic agent, the growth inhibitory agent, the cytotoxic agent, the angiostatic agent, the agent used in the radiation therapy, the anti-VEGF antibody, the FGF antagonist, the PDGF antagonist, or the antibody that binds to the ErbB2, the EGFR, the ErbB3, the ErbB4 or the VEGF receptor is administered as a third therapeutic agent.

Abstract:
PROBLEM TO BE SOLVED: To provide a means for preventing death of neurons that is one main cause of various nervous disorders from acute injury to long-term degeneration, and for elongating the life of neurons. SOLUTION: The invention discloses a method of protecting neurons in mammals from injury-induced pathological changes and a method of treating neuronal damage in mammals, by administering artemin or its agonist, which is unexpectedly and completely free of harmful side-effects (particularly hyperalgesia) associated with administration of neurotropic factors (for example NGF) in many cases.

Abstract:
PROBLEM TO BE SOLVED: To identify a new member of the heregulin superfamily. SOLUTION: The new member of the heregulin superfamily has been identified which is designated as "γ-HRG". The molecule, secreted from human breast cancer MDA-MB-175 cells, promotes the formation of a constitutive active receptor complex and stimulates the growth of these cells in an autocrine manner. The γ-HRG polypeptide and a nucleic acid are disclosed, together with various applications therefor (e.g. use of γ-HRG nucleic acid for the recombinant production of γ-HRG). The γ-HRG antagonists (e.g. neutralizing antibodies and antisense nucleic acid molecules) as well as applications therefor are also described. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an apoptotic anti-ErbB2 antibody. SOLUTION: The anti-ErbB2 antibodies are described which bind to an epitope in Domain 1 of ErbB2 and induce cell death via apoptosis. Various uses for these antibodies are also described. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a new composition and a new method useful for diagnosing and treating immune-related diseases in mammals including humans, and to provide proteins (agonist and antagonist antibodies) stimulating or inhibiting immune responses of mammals. SOLUTION: New polypeptides which are homologs of IL-17 and receptors thereof and nucleic acid molecules encoding those peptides, vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising these polypeptides fused to heterologous polypeptide sequences, antibodies binding to these polypeptides and methods for producing the polypeptides are provided.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for reducing the viscosity of formulations containing proteins because concentrated protein formulations are increased in viscosity and the protein formulations are added with much lyoprotectant such as sugar and treated by freeze drying to keep its stability and thereby sugar increases intermolecular interaction to increase viscosity so the high viscosity formulations are hard in performing preparation, sucking into a syringe and hypodermic injection. SOLUTION: The protein formulations with high viscosity are reduced in viscosity without much injured in stability and biological activity by (1) increasing total ionic strength by adding a salt or a buffer component, or (2) decreasing (from about 4.0 to about 5.3) or increasing (from about 6.5 to about 12.0) pH of the formulations.

Abstract:
PROBLEM TO BE SOLVED: To provide an anti-CD20 antibody, and to provide a method for treating B-cell-associated diseases. SOLUTION: The anti-CD20 antibody is a monoclonal antibody and the antibody binding to the CD20 is humanized or chimeric. Humanized 2H7 variants include those that have amino acid substituents in FR and maturation variants having changes in grafted CDRs. The anti-CD20 antibody is effective in depleting B cells of primates in vivo and treatment of CD20 positive malignancies and autoimmune diseases can be carried out. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide novel antibody variants, particularly anti-HER2 antibody variants having substitutions at positions within the variable domains of the heavy and light chains. SOLUTION: The present invention is based on the finding that particular amino acids of the humanized anti-HER2 antibody hu4D5-8, determined by alanine scanning to be necessary for antigen binding, and other amino acids found by alanine scanning to be relatively unimportant for antigen binding, may be substituted to produce variants having high affinity for HER2.
