NCIt definition : A monoclonal antibody against C-C-chemokine receptor 8 (CCR8), with potential immunomodulating
and antineoplastic activities. Upon administration, anti-CCR8 monoclonal antibody
LM-108 targets, binds to and blocks the activity of CCR8 on CCR8-positive tumor-infiltrating
regulatory T-cells (Tregs) in the tumor microenvironment (TME) and prevents chemokine
ligand 1 (CCL1)-CCR8-mediated signaling. This may reactivate antitumor immune responses.
CCR8 is specifically expressed by tumor-infiltrating Tregs in multiple types of cancer
and plays a key role in immunosuppression. High expression is correlated with poor
prognosis.;
