Title (EN) MULTI-SPECIFIC ANTIBODIES AND METHODS OF MAKING AND USING THEREOF
(FR) ANTICORPS MULTISPÉCIFIQUES ET PROCÉDÉS DE FABRICATION ET D'UTILISATION ASSOCIÉS
Abstract:
(EN) The disclosure provides a tetra-specific antibody monomer having a N-terminal and a C-terminal, comprising in tandem from the N-terminal to the C-terminal, a first scFv domain at the N-terminal, a second scFv domain, a Fab domain, a Fc domain, and a third scFv at the C-terminal, wherein the first scFv domain, the second scFv domain, the Fab domain, and the third scFv domain each has a binding specificity against a different antigen. In one embodiment, the antigen is a tumor antigen, an immune signaling antigen, or a combination thereof. In one embodiment, the antigen includes CD19, CD3, CD137, 4-1BB, and PD-L1. Multi-specific antibodies comprising the disclosed tetra-specific antibodies are also provided.
(FR) L'invention concerne un monomère d'anticorps tétraspécifique ayant une extrémité N-terminale et une extrémité C-terminale, comprenant en tandem de l'extrémité N-terminale à l'extrémité C-terminale, un premier domaine scFv à l'extrémité N-terminale, un domaine Fab, un domaine Fc, un deuxième domaine scFv et un troisième scFv à l'extrémité C-terminale, le premier domaine scFv, le domaine Fab, le deuxième domaine scFv et le troisième domaine scFv ayant chacun une spécificité de liaison vis-à-vis d'un antigène différent. Dans un mode de réalisation, l'antigène est un antigène tumoral, un antigène de signalisation immunitaire, ou une combinaison de ceux-ci. Dans un mode de réalisation, l'antigène comprend CD19, CD3, CD137, 4-1BB et PD-L1. L'invention concerne également des anticorps multispécifiques comprenant les anticorps tétraspécifiques de l'invention.
