  • Patent number: 11918606
    Abstract: A family of chimeric antigen receptors (CARs) containing a CD123 specific scFv was developed to target different epitopes on CD123. In some embodiments, such a CD123 chimeric antigen receptor (CD123CAR) gene includes an anti-CD123 scFv region fused in frame to a modified IgG4 hinge region comprising an S228P substitution, an L235E substitution, and optionally an N297Q substitution; a costimulatory signaling domain; and a T cell receptor (TCR) zeta chain signaling domain. When expressed in healthy donor T cells (CD4/CD8), the CD123CARs redirect T cell specificity and mediated potent effector activity against CD123+ cell lines as well as primary AML patient samples. Further, T cells obtained from patients with active AML can be modified to express CD123CAR genes and are able to lyse autologous AML blasts in vitro. Finally, a single dose of 5.0×106 CAR123 T cells results in significantly delayed leukemic progression in mice.

  • Publication number: 20230338531
    Abstract: Immune cells, including T cells, expressing a chimeric antigen receptor targeted to CD45 are described. In some cases, the immune cells lack a functional CD45 gene. In some cases, the immune cells also include a modification (a suicide sequence) that allows the cells to be killed in vivo. The immune cells are useful for treating a variety of cancers.
