Abstract
The present invention relates to a new antibody or an antigen binding fragment thereof for use in the treatment of cancer by targeting a B cell malignancy, a chimeric antigen receptor comprising the same, and a use of the same. The antibody of the present invention is an antibody for specifically binding to CD19 that is highly expressed in cancer cells (particularly, blood cancer), has very low homology to a CDR sequence thereof compared to a CDR sequence of a conventional CD19 target antibody so that the sequence thereof is unique, and specifically binds to an epitope that is different from a FMC63 antibody fragment binding to CD19 of the conventional art. A cell expressing the chimeric antigen receptor comprising an anti-CD19 antibody or the antigen binding fragment of the present invention induces immune cell activity in response to a positive cell line expressing CD19.
