Abstract

An isolated chimeric antigen receptor polypeptide (CAR), wherein the CAR comprises an extracellular antigen-binding domain, comprising an antibody or antibody fragment that binds a B Cell Maturation Antigen (BCMA) polypeptide. The CAR preferably binds an epitope comprising one or more amino acids of residues 13 to 32 of the N-terminus of human BCMA. Also disclosed is a nucleic acid molecule encoding the CAR of the invention, a genetically modified immune cell, preferably a T cell, expressing the CAR of the invention and the use of said cell in the treatment of a medical disorder associated with the presence of pathogenic B cells, such as a disease of plasma cells, memory B cells and/or mature B cells, in particular multiple myeloma, non-Hodgkin's lymphoma or autoantibody-dependent autoimmune diseases.
