Title
(EN) ANTI-EGFRVIII ANTIBODIES AND ANTIGEN-BINDING FRAGMENTS THEREOF
(FR) ANTICORPS ANTI-EGFRVIII ET LEURS FRAGMENTS DE LIAISON À L'ANTIGÈNE
Abstract
(EN)
Antigen-binding agents such as antibodies or antigen-binding fragments thereof, chimeric antigen receptors (CARs), bispecific T-cell engagers (BiTEs) and the like that specifically bind to epidermal growth factor receptor variant III (EGFRvIII) are provided. The EGFRvIII-specific antibodies or antigen-binding fragments, CARs and BiTEs thereof may be used for the treatment of cancer. Antibody drug conjugates targeting EGFRvIII-expressing cells are particularly contemplated.
(FR)
L'invention concerne des agents de liaison à l'antigène tels que des anticorps ou des fragments de liaison à l'antigène de ceux-ci, des récepteurs antigéniques chimériques (CAR), des activateurs de lymphocytes T bispécifiques (BiTE) et analogues qui se lient de manière spécifique à la variante III du récepteur du facteur de croissance épidermique (EGFRvIII). Les anticorps spécifiques de EGFRvIII ou les fragments de liaison à l'antigène, les CAR et les BiTE de ceux-ci peuvent être utilisés pour le traitement du cancer. L'invention concerne en particulier des conjugués anticorps-médicament ciblant des cellules exprimant EGFRvIII.
