NCIt synonyms : LGR5-targeted Autologous CAR-T Cells CNA3103; Leucine-rich Repeat-containing G Protein-coupled Receptor 5-targeted Autologous CAR
T-cells CNA3103;
NCIt definition : A preparation of autologous T-lymphocytes transduced to express a chimeric antigen
receptor (CAR) targeting the cancer stem cell (CSC) marker leucine-rich repeat-containing
G-protein coupled receptor 5 (LGR5), with potential immunomodulating and antineoplastic
activities. Upon administration, the autologous anti-LGR5 CAR-T cells CNA3103 selectively
target, binds to and lyse LGR5-expressing tumor cells. LGR5, a member of the Wnt signaling
pathway, is overexpressed on certain cancer cells; it plays a key role in CSC proliferation
and survival, tumor initiation, growth, and metastasis. Its expression is linked to
poor survival and poor patient response to therapy. CNA3103 contains the antigen-biding
domain of the humanized monoclonal LGR5 antibody BNC101.;
