Antibodies that bind human interleukin-18 and methods of making and using

Abstract

Antibodies that bind human interleukin-18 (hIL-18) are provided, in particular antibodies that bind epitope(s) of human IL-18. The antibodies can be, for example, entirely human antibodies, recombinant antibodies, or monoclonal antibodies. Preferred antibodies have high affinity for hIL-18 and neutralize hIL-18 activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. Method of making and method of using the antibodies of the invention are also provided. The antibodies, or antibody portions, of the invention are useful for detecting hIL-18 and for inhibiting hIL-18 activity, e.g., in a human subject suffering from a disorder in which hIL-18 activity is detrimental.

30 claims: 7 independent, 23 dependent

  1. 1
    An isolated human antibody, or an antigen-binding portion thereof, comprising at least one variable region CDR domain capable of binding an epitope of human IL-18.
  2. 11
    An isolated antibody, or an antigen-binding portion thereof, that binds an epitope of human IL-18, or portion thereof, comprising an amino acid sequence selected from the group comprising SEQ ID NO:3 and SEQ ID NO: 33.
  3. 22
    A pharmaceutical composition comprising the antibody, or antigen-binding portion thereof, of any one of claims 1-17, and a pharmaceutically acceptable carrier and, optionally at least one additional therapeutic agent for treating a disorder in which IL-18 activity is detrimental, optionally selected from the group consisting of an antibody, or fragment thereof, capable of binding human IL-12, methotrexate anti-TNF, corticosteroids, cyclosporin, rapamycin, FK506, and non-steroidal anti-inflammatory agents.
  4. 27
    A method for inhibiting human IL-18 activity comprising contacting human IL-18 with the antibody, or antigen-binding portion thereof, of any one of claims 1-17 such that human IL-18 activity is inhibited.
  5. 28
    A method for inhibiting human IL-18 activity in a human subject suffering from a disorder in which IL-18 activity is detrimental, comprising administering to the human subject the antibody, or antigen-binding portion thereof, of any one of claims 1-17 such that human IL-18 activity in the human subject is inhibited.
  6. 29
