LAG-3 and PD-1 are two distinct immune checkpoints1,3
Relatlimab binds to the LAG-3 receptor and blocks its interaction with ligands, including MHC II, reducing LAG-3 pathway–mediated inhibition of the immune response, thereby promoting T cell proliferation and cytokine secretion1
Nivolumab binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, thereby relieving T cell exhaustion and improving cytokine production1
The combination of nivolumab- and relatlimab-mediated inhibition increases T cell activity compared to the activity of either antibody alone1
Targeting of normal cells can occur.
The illustrated mechanism of action may vary for each patient and may not directly correlate with clinical significance.
APC=antigen-presenting cell; LAG-3=lymphocyte-activation gene-3; MHC II=major histocompatibility complex II; MOA=mechanism of action; PD-1=programmed cell death protein-1; PD-L1=programmed death-ligand 1; PD-L2=programmed death-ligand 2.
