NCIt definition : A preparation of autologous T-lymphocytes that have been genetically modified to express
a killer cell immunoglobulin-like receptor (KIR)-based chimeric antigen receptor (CAR)
consisting of an anti-mesothelin (MSLN) single chain variable fragment (scFv) fused
to the transmembrane and cytoplasmic domains of the stimulatory KIR 2DS2 (KIR2DS2),
and the immunoreceptor tyrosine-based activation motif (ITAM)-containing adaptor protein
and costimulatory chain DAP12, with potential immunomodulating and antineoplastic
activities. Upon administration, the autologous anti-MSLN KIR-CAR-transduced T-cells
SynKIR-110 specifically target and kill MSLN-expressing tumor cells. Mesothelin, a
tumor-associated antigen (TAA) and cell surface glycoprotein involved in cell adhesion,
is overexpressed in a variety of cancer cell types. KIR is normally expressed by natural
killer (NK) cells, and KIR-based CAR may decrease T-cell exhaustion and enhance T-cell
persistence.;
