CCR8 Inhibitor

ML604086 is a selective CCR8 inhibitor, inhibiting CCL1 binding to CCR8 on circulating T-cells. ML604086 inhibits CCL1 mediated chemotaxis and increases in intracellular Ca²⁺ concentrations.

Lanerkitug (FUT8-KO) (BAY3375968 (FUT8-KO)) is an anti-CCR8 monoclonal antibody expressed by CHO cells with the fucosyltransferase 8 gene (FUT8) knocked out. Fucose deficiency enhances the ADCC effect of the antibody. Lanerkitug (HY-P991942) selectively depletes human CCR8+Tregs via antibody dependent cellular cytotoxicity (ADCC) and antibody dependent cellular phagocytosis (ADCP). Lanerkitug can be used in the research of solid tumors.

S-531011 (FUT8-KO) is an anti-CCR8 monoclonal antibody expressed by CHO cells with the fucosyltransferase 8 gene (FUT8) knocked out. Fucose deficiency enhances the antibody-dependent cellular cytotoxicity (ADCC) effect of the antibody. S-531011 (FUT8-KO) can be used for the research of cancer immunity.

Enzelkitug (RO-7502175; RG-6411) (FUT8-KO) is an anti-CCR8 monoclonal antibody expressed by CHO cells with the fucosyltransferase 8 gene (FUT8) knocked out. Fucose deficiency enhances the antibody-dependent cellular cytotoxicity (ADCC) effect of the antibody. Enzelkitug (FUT8-KO) can be used for the research of various solid tumors and hematological malignancies.

Tagmokitug (CHS-114; SRF-114) is a fully human IgG1 antibody targeting CCR8. Tagmokitug selectively binds to human CCR8 (K_d = 502 pM) and mediates the death of CCR8-expressing cells via antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis. Tagmokitug selectively eliminates intratumoral regulatory T cells, induces tumor growth inhibition, remodels the tumor immune microenvironment, and promotes the differentiation of cytotoxic CD8⁺ T cell subsets. Tagmokitug can be used for the research of solid tumors.

S-531011 is a high-affinity, selective, and reversible CCR8 ligand with antibody-dependent cellular cytotoxicity (ADCC) against CCR8-expressing cells. S-531011 induces the death of tumor-infiltrating CCR8⁺ regulatory T cells while preserving regulatory T cells in peripheral blood, thereby reinvigorating anti-tumor immunity. The combination of S-531011 with anti-PD-1 antibody effectively inhibits tumor growth, and S-531011 can be used for research on advanced solid tumors and various cancers including non-small cell lung cancer, ovarian cancer, colon cancer, breast cancer, and pancreatic ductal adenocarcinoma.

Lanerkitug (BAY3375968) is a fully human monoclonal IgG1 anti-human CCR8 antibody. Lanerkitug selectively depletes human CCR8⁺ Tregs via antibody dependent cellular cytotoxicity (ADCC) and antibody dependent cellular phagocytosis (ADCP). Lanerkitug can be used in the research of solid tumors.

CM369 is a humanized monoclonal antibody against CCR8 that possesses potential immunomodulatory and anti-tumor activities. CM369 can be used in cancer research.

ZL-1218 (FUT8-KO) is an anti-CCR8 monoclonal antibody expressed by CHO cells with the fucosyltransferase 8 gene (FUT8) knocked out. Fucose deficiency enhances the antibody-dependent cellular cytotoxicity (ADCC) effect of the antibody. ZL-1218 (FUT8-KO) can be used for the research of solid tumour.

HFB101110 is a human-derived inhibitor and Treg depleter that specifically targets CCR8. It does not bind to the homologous CCR4 receptor and is mainly used in research on solid tumors, renal cell carcinoma and colorectal cancer. HFB101110 blocks hCCL1 binding by interacting with the N-terminal extracellular domain of hCCR8, thereby inhibiting hCCL1-induced calcium influx, chemotaxis and downstream signaling pathways. Meanwhile, HFB101110 can mediate ADCC effects to specifically deplete CCR8-positive cells, including intratumoral Tregs. HFB101110 exhibits favorable anti-tumor activity and pharmacokinetic properties.

Enzelkitug is a humanized immunoglobulin G1-κ monoclonal antibody targeting the human C-C motif chemokine receptor 8 (CCR8). Enzelkitug is promising for research of various solid tumors and hematological malignancies.

ZL-1218 is a selective humanized IgG1 antibody, targeting CCR8. ZL-1218 induces antibody-dependent cellular cytotoxicity (ADCC), leading to NK cell-mediated depletion of CCR8-expressing regulatory T cells (Tregs). ZL-1218 blocks the binding of the CCR8 ligand CCL1 to CCR8 and reduces Treg recruitment by inhibiting the chemotaxis of CCR8⁺ cells. ZL-1218 reduces intratumoral Treg levels in a dose-dependent manner. ZL-1218 exerts enhanced antitumor activity when combined with the anti-PD-1 antibody. ZL-1218 can be used for solid tumour research.
