The present disclosure relates to compositions and methods for compositions, methods, and kits for treating cancer using chimeric antigen receptor (CAR) modified cells. Some embodiments of the present disclosure relate to an isolated nucleic acid sequence encoding CAR. The CAR may include an antigen binding domain, a transmembrane domain, a costimulatory signaling region, and a CD3 zeta signaling domain. The antigen binding domain may bind to an antigen of a non-essential organ.

This present invention relates to BCMA binders (e.g. antibodies) and chimeric antigen receptor (CAR) constructs comprising a BCMA antigen binding molecule. The BCMA binders specifically bind to BCMA. The present BCMA CARs further comprise a hinge region (e.g., CD28 hinge), a transmembrane domain, and one or more intracellular NK cell signalling domains. NK cells expressing a BCMA CAR has increased efficacy in killing cancer cells. Provided herein also include therapeutic uses of the BCMA binders and BCMA CARs.
