CA 2543920

The present invention encompasses IL-18 binding proteins, particularly antibodies that bind human interleukin-18 (hIL-18). Specifically, the invention relates to antibodies that are entirely human antibodies. Preferred antibodies have high affinity for hIL-18 and/or that 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.

La présente invention a trait à des protéines de liaison IL-18, notamment des anticorps de liaison de l'interleukine 18 humaine. De manière spécifique, la présente invention a trait à des anticorps qui sont entièrement des anticorps humains. Des anticorps préférés présente une affinité élevée pour l'interleukine 18 humaine et/ou neutralisent l'activité de l'interleukine 18 humaine in vitro et in vivo. Un anticorps de l'invention peut être un anticorps pleine longueur ou une portion de liaison à l'antigène de celui-ci. L'invention a également trait à un procédé de fabrication et un procédé d'utilisation des anticorps de l'invention. Les anticorps, ou portions d'anticorps, de l'invention sont utiles pour la détection de l'interleukine 18 humaine et pour l'inhibition de l'activité de l'interleukine 18 humaine, par exemple chez un sujet humain atteint d'un trouble dans lequel l'activité de l'interleukine 18 humaine est nuisible.
