Despite the promise of chimeric antigen receptor (CAR) T cell therapy, predicting patient response is challenging. Single-cell multiomics of myeloma treated with B cell maturation antigen (BCMA)-targeted CAR T cells now reveal that poor clinical response is associated with an immunosuppressive environment and CAR T cells transition to exhausted phenotypes, indicating a mechanism for reduced persistence.
