NCIt definition : A monoclonal antibody directed against the human cell surface glycoprotein ADP-ribosyl
cyclase 1 (CD38), with potential antineoplastic activity. Upon administration, lumrotatug
specifically targets and binds to CD38 expressed on tumor cells. This may trigger
antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity
(CDC), antibody-dependent cellular phagocytosis (ADCP) and apoptosis, resulting in
cell lysis and depletion of CD38-expressing tumor cells. In addition, lumrotatug inhibits
the extracellular enzyme activity of CD38. CD38, a type II transmembrane glycoprotein,
is present on various immune cells and hematologic malignancies. It plays an important
role in the regulation of migration and receptor-mediated adhesion, as well as various
cell functions through its multiple ecto- and endo-enzymatic activities.;
