tagmokitug

A human immunoglobulin G1 (IgG1) afucosylated monoclonal antibody against C-C-chemokine receptor 8 (CCR8), with potential immunomodulating and antineoplastic activities. Upon administration, tagmokitug targets and binds to CCR8 on CCR8-positive tumor-infiltrating regulatory T cells (Tregs) in the tumor microenvironment (TME), and depletes CCR8-positive tumor-infiltrating Tregs via antibody-dependent cellular cytotoxicity (ADCC) and antibody dependent cellular phagocytosis (ADCP). 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.
