ABOUT IMM2510
IMM2510, independently developed by the Group, is a bispecific molecule with a mAbTrap structure targeting vascular endothelial growth factor (VEGF) and programmed cell death ligand 1 (PD-L1). IMM2510 can inhibit angiogenesis, leading to tumor shrinkage, and sensitize tumor cells to immune responses, while activating T cells, NK cells, and macrophages via the blockade of PD-L1/programmed cell death protein 1 (PD-1) interaction and the induction of Fc-mediated antibody-dependent cellular cytotoxicity (ADCC)/antibody-dependent cellular phagocytosis (ADCP) activity.

ABOUT IMM27M
IMM27M is a new generation cytotoxic T-lymphocyte-associated protein 4 (CTLA-4)antibody with enhanced ADCC activity. It can induce potent immune responses targeting CTLA-4 overexpressed immune-suppressive Treg cells and promote Treg depletion from the tumor microenvironment (TME), thus enhancing T-cell antitumor response.
