A defucosylated, humanized IgG1 monoclonal antibody directed against the extracellular domain of the human CD70 molecule with potential antineoplastic activity. Upon administration, anti-CD70 monoclonal antibody ARGX-110 selectively binds to, and neutralizes the activity of CD70, which may also induce an antibody-dependent cellular cytotoxicity (ADCC) response against CD70-expressing tumor cells. CD70, the ligand for the costimulatory receptor CD27 and a member of the tumor necrosis factor (TNF) family, is found on a number of solid and hematological tumors. Its overexpression may play an important role in evasion of immune surveillance. Check for active clinical trials using this agent.
