Title:
FUSION PROTEIN
Document Type and Number:
WIPO Patent Application WO/2024/005204
Kind Code:
A1
Abstract:
Provided is a novel protein, or the like, as a trispecific tribody in which antitumor effects have been augmented. The present invention relates to a fusion protein comprising a first chain and a second chain which are different from one another. Three types of combined VH/VL binding domains formed in the fusion protein have any one binding capability selected from: (i) a binding capability with respect to 5T4; (ii) a binding capability with respect to a T-cell CD3 receptor complex; and (iii) a binding capability with respect to PD-1, PD-L1, or LAG3 (note that the three types of combined VH/VL binding domains all have binding capabilities different from one another).
