Abstract
(EN)
The present disclosure relates to a CD3 antibody and a pharmaceutical use thereof. Specifically, the present disclosure relates to forming a multi-specificity antibody by using a CD3 antibody and binding molecules of another target. The multi-specificity antibody may simultaneously bind to CD3 and another tumor-associated antigen, and bind and activate CD3-positive T cells while binding tumor-associated antigen-expressing cells, thereby promoting T cells specifically killing tumor cells that express tumor-associated antigens. In addition, the present disclosure also provides a preparation and application of a multi-specificity antibody.
(FR)
La présente invention concerne un anticorps CD3 et son utilisation pharmaceutique. Plus particulièrement, la présente invention concerne la formation d'un anticorps multi-spécifique à l'aide d'un anticorps CD3 et des molécules de liaison d'une autre cible. L'anticorps multi-spécifique peut se lier simultanément à CD3 et à un autre antigène associé à une tumeur, et se lient et activent des lymphocytes T positifs au CD3 tout en se liant à des cellules exprimant un antigène associé à une tumeur, favorisant ainsi des lymphocytes T détruisant de manière spécifique des cellules tumorales exprimant des antigènes associés à une tumeur. De plus, la présente invention concerne également une préparation et une utilisation d'un anticorps multi-spécifique.
