    ARGX-110

    Fc Receptor (FcR) NF-κB Inflammation/Immunology Cancer
    Cusatuzumab (ARGX-110) is a selective competitive blocker targeting CD70 (with an equilibrium dissociation constant of 17 pM for binding to human CD70). Cusatuzumab also possesses enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) activity. It is a humanized IgG1 monoclonal antibody, artificially synthesized through humanization and genetic engineering modifications (CH2 region mutation to enhance effector function). Cusatuzumab has a dual mechanism of action: firstly, it competitively blocks the interaction between CD70 and CD27, inhibiting the CD27-NF-κB signaling pathway, reducing regulatory T cell (Treg) activation and tumor cell proliferation; secondly, by enhancing binding to FcγRIIIa, it mediates ADCC and antibody-dependent cellular phagocytosis (ADCP), directly lysing CD70-positive tumor cells. Cusatuzumab can efficiently eliminate leukemia stem cells (LSCs), induce tumor cell differentiation and apoptosis, restore immune surveillance, and target CD70-positive tumors. Cusatuzumab is used in the study of acute myeloid leukemia (AML) .
