Abstract: Provided herein is a method of treating a subject who has a cancer. At least one dose of chimeric antigen receptor (CAR)-T cells comprising a CAR comprising a polypeptide is administered to the subject. The peptide comprises an extracellular antigen binding domain with at least two BCMA-binding moieties, a transmembrane domain, and an intracellular signaling domain. The dose of CAR-T cells administered to the subject is from 4.0×105 to 1.0×106 of CAR-T cells per kilogram of the subject's mass. Alternatively, the dose comprises 1×106 to 1×108 of the CAR-T cells.

Abstract: Provided herein are methods of treating a subject who has multiple myeloma and has received one to three prior treatment(s). Infusions of chimeric antigen receptor (CAR)-T cells comprising a CAR capable of specifically binding to an epitope of BCMA are administered to the subject.

Abstract: Provided herein are methods of treating a subject who has multiple myeloma and has received an initial therapy, including a stem cell transplantation. Infusions of chimeric antigen receptor (CAR)-T cells comprising a BCMA CAR comprising a polypeptide are administered to the subject. In certain embodiments, the dose of CAR-T cells administered to the subject is from 1.0×105 to 5.0×106 of CAR-T cells per kilogram of the subject's mass. The method of treatment is effective in obtaining and maintaining minimal residual disease negativity status, as well as other beneficial clinical outcomes related to efficacy and safety.

Abstract: Provided herein is a method of treating a subject who has multiple myeloma. A single infusion of chimeric antigen receptor (CAR)-T cells comprising an anti-BCMA CAR comprising a polypeptide is administered to the subject. In certain embodiments, the dose of CAR-T cells administered to the subject is from 1.0×105 to 5.0×106 of CAR-T cells per kilogram of the subject's mass.
