Abstract: A method for assessing responsiveness of a subject to a treatment comprising T cells expressing a bivalent BCMA-targeting chimeric antigen receptor (CAR), comprising administering to the subject the T cells, and assessing the responsiveness of the subject to the treatment based on time length the subject maintains minimal residual disease (MRD) negative status.

Abstract: Provided herein are methods of treating a subject who has multiple myeloma and has received prior treatment and has limited treatment options. Infusions of chimeric antigen receptor (CAR)-T cells comprising an anti-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 are methods of treating a subject who has multiple myeloma with a ciltacabtagene autoleucel suspension. Also provided are pharmaceutical products containing ciltacabtagene autoleucel suspensions, instructions for use of the ciltacabtagene autoleucel suspensions, and methods for selling a drug product containing ciltacabtagene autoleucel suspensions.
