BISPECIFIC ANTIBODY COMBINATION AND USE THEREOF
Provided are a bispecific antibody combination and a use thereof. The bispecific antibody combination comprises a bispecific antibody I and a bispecific antibody II. The bispecific antibody I comprises a CD3-targeting domain and a tumor-associated antigen-targeting domain, and the bispecific antibody II comprises a 4-1BB-targeting domain and a tumor-associated antigen-targeting domain. Further provided are a pharmaceutical composition, a test kit, a kit of parts and an administration device containing the same, and a method of treating cancer by using the same. The concomitant use of the bispecific antibodies not only reduces the exhaustion of T cells, but also significantly facilitates tumor killing at a later stage. Moreover, the concomitant use of the bispecific antibodies, especially when targeting different epitopes of the same tumor-associated antigen or targeting different tumor-associated antigens, produces a strong synergistic killing effect. The use of the bispecific antibody combination and the pharmaceutical composition containing the same provides a potential clinical solution for effectively treating solid tumors..
