NCIt related terms : MCARH109;
NCIt definition : A preparation of autologous T-lymphocytes that have been transduced with a retroviral
vector expressing a chimeric antigen receptor (CAR) containing a single chain variable
fragment (scFv) specific for the tumor-associated antigen (TAA) human G-protein coupled
receptor family C group 5 member D (GPRC5D) and the co-stimulatory domain 4-1BB (CD137),
with potential immunostimulating and antineoplastic activities. Upon leukapheresis,
isolation, transduction, expansion ex vivo, and reintroduction into the patient, the
autologous anti-GPRC5D-CAR-4-1BB-expressing T-cells MCARH109 specifically recognize
and induce selective toxicity in GPRC5D-expressing tumor cells. GPRC5D is overexpressed
in certain malignancies, such as multiple myeloma, while minimally expressed in normal,
healthy cells. It plays a key role in tumor cell proliferation.;
