摘要:
USE OF AN ANTI-CD3 HUMAN ANTIBODY. The present invention provides methods of treating, preventing, slowing the progression, or ameliorating the symptoms of T cell-mediated immune diseases, particularly autoimmune diseases (for example, autoimmune diabetes (i.e., type 1 diabetes or insulin-dependent diabetes mellitus (IDDM )) and multiple sclerosis) using human anti-CD3 antibodies. The antibodies of the invention are preferably used in low dose dosing regimens, chronic dosing regimens or regimens that involve redose after a certain period of time. The methods of the invention provide administration of antibodies that specifically bind to the epsilon subunit within the human CD3 complex. Such antibodies modulate the alloantigen / T cell receptor interaction and thus regulate T cell-mediated cytotoxicity associated with autoimmune disorders. In addition, the methods of the invention provide the use of modified human anti-CD3 antibodies such that they exhibit reduced or eliminated effector function and T cell activation when compared to unmodified human anti-CD3 antibodies.USO DE UM ANTICORPO HUMANO ANTI-CD3. A presente invenção fornece métodos de tratar, prevenir, diminuir a progressão, ou melhorar os sintomas de doenças imunológicas mediadas pela célula T, particularmente doenças autoimunes (por exemplo, diabetes autoimune (isto é, diabetes tipo 1 ou diabetes melito dependente de insulina (IDDM)) e esclerose múltipla) através do uso de anticorpos humanos anti-CD3. Os anticorpos da invenção são preferivelmente usados em regimes de dosagem de dose baixa, regimes de dosagem crónica ou regimes que envolvem a redosagem depois de um certo período de tempo. Os métodos da invenção fornecem a administração de anticorpos que especificamente se ligam à subunidade épsilon dentro do complexo CD3 humano. Tais anticorpos modulam a interação de aloantígeno/receptor de célula T e, assim, regulam a citotoxicidade mediada pela célula T associada com distúrbios autoimunes. Adicionalmente
