NCIt definition : A recombinant humanized 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
LM-102 specifically targets and binds to CLDN18.2 expressed on tumor cells. This may
kill CLDN18.2-expressing tumor cells and inhibit tumor cell proliferation. CLDN18.2,
a tight junction protein and stomach-specific isoform of claudin-18, is expressed
on a variety of tumor cells, but its expression in healthy tissues is strictly confined
to short-lived differentiated epithelial cells of the gastric mucosa.;
