CA 2749966

The present invention encompasses IL-1.alpha. binding proteins. Specifically, the invention relates to antibodies that are chimeric, CDR grafted and humanized antibodies. Antibodies of the invention have high affinity for IL-1.alpha. and neutralize IL-1.alpha. activity. 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 IL-1.alpha. and for inhibiting IL-1.alpha. activity, e.g., in a human subject suffering from a disorder in which IL-1.alpha. activity is detrimental.

La présente invention concerne des protéines de liaison à IL-1a. Spécifiquement, l'invention concerne des anticorps qui sont des anticorps chimères, à greffe de CDR et humanisés. Les anticorps de l'invention présentent une affinité élevée pour IL-1a et neutralisent l'activité d'IL-1a. Un anticorps de l'invention peut être un anticorps pleine-longueur ou une partie de liaison à l'antigène de celui-ci. L'invention concerne également un procédé de fabrication et un procédé d'utilisation des anticorps de l'invention. Les anticorps, ou les parties d'anticorps, de l'invention sont utiles pour détecter IL-1a et pour inhiber l'activité d'IL-1a, par exemple chez un sujet humain souffrant d'un trouble dans lequel l'activité d'IL-1a est préjudiciable.
