-
A preparation of autologous T lymphocytes that have been genetically modified and transduced with a lentiviral vector expressing a chimeric antigen receptor (CAR) targeting the tumor-associated antigen (TAA) CD19 and containing, as of yet undisclosed co-stimulatory signaling domains, with potential immunostimulating and antineoplastic activities. Upon administration, autologous anti-CD19 CAR-T cells IM19 target and bind to CD19-expressing tumor cells, thereby inducing selective toxicity in CD19-expressing tumor cells. CD19 antigen is a B-cell-specific cell surface antigen expressed in all B-cell lineage malignancies.
