Abstract: The present invention discloses reshaped antibody to human medulloblastoma cells comprising: (A) an L chain comprising: (1) a human L chain C region, and (2) an L chain V region comprising human L chain FRs and L chain CDRs of mouse monoclonal antibody ONS-M21 to human medulloblastoma cells; and, (B) an H chain containing: (1) a human H chain C region, and (2) an H chain V region comprising human H chain FRs and H chain CDRs of mouse monoclonal antibody ONS-M21 to human medulloblastoma cells. Since the majority of this reshaped human antibody is derived from a human antibody and mouse CDRs have a low level of antigenicity, the reshaped human antibody of the present invention has a low level of antigenicity in humans, and is therefore expected to be useful as a therapeutic agent and diagnostic tool for brain tumors such as medulloblastoma which strongly express antigen that is recognized by this antibody.

Abstract: A humanized antibody against tissue factor (TF), comprising: A: a humanized H chain comprising (1) a H chain V region comprising the H chain CDRs of a mouse monoclonal antibody against TF and the H chain FRs of a human antibody, and (2) the H chain C region of a human antibody; and B: a humanized L chain comprising (1) an L chain V region comprising the L chain CDRs of a mouse monoclonal antibody against TF and the L chain FRs of a human antibody, and (2) the L chain C region of a human antibody. After generating a humanized V region by grafting the CDRs of a mouse monoclonal antibody onto a human antibody, a humanized antibody having a higher activity is searched by replacing the FR of the above region with the corresponding FR of the human antibody having a high homology.

Abstract: A reshaped human antibody to the human IL-6R, comprising: (A) an L chain comprising, (1) a human L chain C region, and (2) an L chain V region comprising human L chain framework regions (FRs), and mouse L chain complementary determination regions (CDRs) of a momoclonal antibody to the IL-6 receptor (IL-6R); and (B) an H chain comprising, (1) a human H chain C region, and (2) an H chain V region comprising human H chain FRS, and mouse H chain CDRs of a monoclonal antibody to the IL-6R. Since major portion of the reshaped human antibody is derived from a human antibody and the mouse CDRs which are less immunogenic, the present reshaped human antibody is less immunogenic to human, and therefor is promised for therapeutic uses.

Abstract: The invention relates to a therapeutic agent for cachexia comprising, as an active ingredient, a substance capable of inhibiting the binding between a parathyroid hormone related protein (PTHrP) and a receptor thereof.

Abstract: A humanized antibody against tissue factor (TF), comprising:

Abstract: The present invention relates to a human/mouse chimeric antibody that includes the variable region of a mouse monoclonal antibody against human tissue factor (TF) and the constant region of a human antibody. The humanized antibody contains light and heavy chain complementarity determining regions of a mouse monoclonal antibody against human TF which have been grafted onto a human antibody. The present invention also provides a therapeutic agent for disseminated intravascular coagulation (DIC) syndrome, which includes a humanized antibody against human TF as an active ingredient.

Abstract: The present invention discloses a reshaped human antibody against human IL-8 comprising:

Abstract: A reshaped human antibody is characterized as having the same binding affinity for IL-8 as a chimeric antibody but with low immunogenicity in comparison. The reshaped antibody has the following elements: a human L chain C region or a human L chain FR and an L chain CDR from a mouse monoclonal antibody against human IL-8 and a human H chain C region or a human H chain FR and an H chain CDR of mouse monoclonal antibody against human IL-8. Since the reshaped human antibody has low immunogenicity to humans, it is suitable for use in medical treatment of a variety of medical conditions.

Abstract: A reshaped antibody comprising:(A) L chains comprising:(1) a human C region, and(2) an L chain V region comprising human L chain FRs and L chain CDRs of a mouse monoclonal antibody; and(B) H chains comprising:(1) a human H chain C region, and(2) an H chain V region comprising human H chain FRs, and H chain CDRs of a mouse monoclonal antibody to human IL-6. Since the major portions of the reshaped human antibody are derived from human, and the mouse CDRs are less immunogenic, then the present reshaped human antibody is less immunogenic, and therefore inhibits information transfer by IL-6, and is promising as a therapeutic agent for diseases caused by IL-6.
