NCIt definition : A preparation of autologous T-lymphocytes (ATL) that have been genetically modified
to express a chimeric antigen receptor (CAR) directed against the kappa light chain
of immunoglobulin (Ig) and linked to the costimulatory domain of CD28, with potential
immunostimulating and antineoplastic activities. Upon administration, the autologous
anti-kappa light chain CAR-CD28-expressing T-lymphocytes target and bind to the kappa
light chain of Ig expressed on tumor cells, resulting in T-cell-mediated tumor cell
lysis. In some B-cell malignancies, the expression of the Ig light chain kappa may
be increased compared to the expression of Ig light chain lambda.;
