autologous anti-CD19/CD22 CAR-T cells AUTO3

A preparation of autologous T lymphocytes that have been transduced with a bicistronic retroviral vector encoding both an anti-CD19 chimeric antigen receptor (CAR) fused to OX40 co-stimulatory domain and an anti-CD22 CAR linked to the intracellular signaling domains of 4-1BB (CD137) and the zeta chain of the TCR/CD3 complex (TCRzeta; CD247; CD3zeta), optimized with a novel pentameric spacer derived from the collagen oligomeric matrix protein (COMP), with potential antineoplastic activity. Upon administration, the autologous anti-CD19/CD22 CAR T cells AUTO3 bind to and induce selectivity in tumor cells expressing CD19 and CD22. CD19 and CD22, both transmembrane phosphoglycoproteins expressed on the surface of cells in the B lineage, are often overexpressed on malignant B cells. By simultaneously targeting two B-cell antigens, this preparation may minimize relapse due to single antigen loss in patients with B-cell malignancies.
