NCIt definition : A preparation of autologous human T-lymphocytes that are genetically engineered to
express a chimeric antigen receptor (CAR) targeting the tumor-associated antigen (TAA)
CD22, with potential immunostimulating and antineoplastic activities. Upon administration,
the autologous anti-CD22 CAR-expressing T-cells SCRI-CAR22v2 express anti-CD22-CAR
on their cell surfaces and bind to the CD22 antigen on tumor cell surfaces leading
to lysis of CD22-expressing B-cells. CD22, a B-lineage-restricted, transmembrane phosphoglycoprotein,
is expressed on malignant B-cells.;
