Use of monoclonal antibodies for the treatment of inflammation and bacterial infections

Abstract

A composition includes monoclonal antibodies directed against a circulating proinflammatory cytokine, the antibodies having a high affinity for the FcγRIIIa receptor (CD16), in particular the fucose level of all of the antibodies of the composition being less than 60%, and preferably less than 50%, and in particular, the galactosylation level of all of the antibodies of the composition being at least 60%, for the use thereof in the context of the prevention or treatment of the early phases of inflammation. A composition including monoclonal antibodies directed against a circulating bacterial toxin, having an improved affinity for the FcγRIIIa receptor (CD16) with respect to antibodies directed against the bacterial toxin, produced in the CHO cell line, for the use thereof in the context of the prevention or treatment of the early phases of a bacterial infection linked to the release of the toxin is also described.
