NCIt definition : A human monoclonal antibody directed against the tumor-associated antigen (TAA) Claudin18.2
(CLDN18.2; A2 isoform of claudin-18), with potential immunostimulating and antineoplastic
activities. Upon administration, anti-CLDN18.2 monoclonal antibody NBL-015 specifically
targets, binds to and inhibits CLDN18.2 expressed on tumor cells. This may trigger
antibody-dependent cellular cytotoxicity (ADCC), antibody-dependent cell mediated
phagocytosis (ADCP) and antibody-mediated complement dependent cytotoxicity (CDC).
This may kill CLDN18.2-expressing tumor cells and inhibit cell proliferation. CLDN18.2,
a tight junction protein and stomach-specific isoform of claudin-18, is expressed
on a variety of tumor cells. Its expression in healthy tissues is strictly confined
to short-lived differentiated epithelial cells of the gastric mucosa.;
