Preclinical evaluation of XB628: A novel PD-L1 x NKG2A bispecific antibody (AACR 2025) - "XB628 is a first-in-class, bispecific antibody that simultaneously inhibits both adaptive and innate immune checkpoints by engaging PD-L1 and NKG2A, while also recruiting NK cells to tumor cells. XB628 is highly efficacious in tumor cell killing in vitro and in vivo, supporting further clinical development."
