NCIt definition : A human immunoglobulin G1 (IgG1) afucosylated monoclonal antibody against C-C-chemokine
receptor 8 (CCR8), with potential immunomodulating and antineoplastic activities.
Upon administration, anti-CCR8 monoclonal antibody BAY3375968 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. BAY3375968 eliminates CCR8-positive Tregs via the induction of Fc-mediated
antibody-dependent cell-mediated cytotoxicity (ADCC) and antibody dependent cellular
phagocytosis (ADCP), thereby depleting CCR8-positive Tregs. This may reactivate antitumor
immune responses. CCR8 is specifically expressed on activated tumor-infiltrating Tregs
in multiple types of cancer and plays a key role in immunosuppression. High expression
is correlated with poor prognosis.;
