drug_description
Autologous, fully human anti-CD19 CAR T-cell therapy that reprograms a patient’s T cells to express a CD19-directed CAR, enabling depletion of CD19+ B-lineage cells to reset B cell–driven immune dysregulation in non-relapsing progressive MS.

Autologous Anti-CD19 CAR-CD8alpha-CD28-CD3zeta T Cells KYV 101
nci_thesaurus_definition
A preparation of autologous CD4- and CD8-positive T-cells that are transduced with a lentiviral vector encoding for a chimeric antigen receptor (CAR) consisting of a human single chain variable fragment (scFv) of anti-CD19 and fused to the hinge and transmembrane domains of CD8alpha co-receptor, the cytoplasmic costimulatory domain of human CD28, and the T-cell antigen receptor complex zeta chain (CD3-zeta), with potential immunostimulating activity. Upon transfusion, autologous anti-CD19 CAR-CD8alpha-CD28-CD3zeta T cells KYV 101 recognize and induce selective toxicity and lysis in CD19-expressing B-cells. CD19, a B-cell-specific cell surface antigen, is overexpressed in B-cell lineage malignancies and in certain B-cell-driven autoimmune diseases.

drug_mechanism_of_action
Autologous T cells are transduced to express a fully human anti-CD19 chimeric antigen receptor (CD8α hinge/transmembrane, CD28 costimulatory, CD3ζ signaling). On binding CD19 on B-lineage cells, the CAR T cells activate and mediate cytotoxic killing and depletion of CD19+ B cells (including naive/memory B cells and plasmablasts), aiming to reset B cell–driven immune dysregulation in multiple sclerosis.
