  • Publication number: 20210061907
    Abstract: The present invention relates to: a novel antibody or an antigen-binding fragment thereof for use in the treatment of cancer by targeting B cell malignancies; a chimeric antigen receptor comprising the same; and uses thereof. The antibody of the present invention is an antibody specifically binding to CD19 highly expressed in cancer cells (particularly, blood cancer) and has very low homology compared to the CDR sequences of conventional CD19 target antibodies, and thus the sequence thereof is unique. In addition, cells expressing a chimeric antigen receptor comprising an anti-CD19 antibody or antigen-binding fragment of the present invention induce immune cell activity in response to a positive cell line expressing CD19, and thus can be usefully used as a therapeutic agent for CAR-immune cells.
