Following the publication of this article, an error was noted in the text of the introduction.
The following paragraph:
“T-cell redirecting bispecific antibodies (bsABs) and CAR-T cells have shown impressive response rates and progression-free survival (PFS) compared to the previous standard of care in RRMM patients [8,9,10,11], and there was hope that the same might hold true for EMD [12, 13]. Indeed, the pivotal KarMMa trial reported an overall response rate (ORR) of over 70% and a survival benefit for EMD patients treated with idecabtagene vicleucel (ide-cel), but this analysis subsumed not only EMD but also paraskeletal disease, making interpretation difficult [14]. In a retrospective analysis, 11 US centers reported outcomes of 84 EMD patients treated with ciltacabtagene autoleucel (cilta-cel), another BCMA-directed CAR-T cell therapy, and found an ORR of 52%, an mPFS of 5.3 months, and an mOS of 14.8 months, with overall inferior outcomes compared to patients without EMD [16]. Similarly, in two other recent real-world analyses of 134 and 255 patients receiving cilta-cel, EMD was associated with significantly lower ORR and both shorter PFS and OS compared to non-EMD patients [17]. Nevertheless, the results were promising compared to historical EMD cohorts.”

A recent real-world analysis of in 236 patients treated with ciltacabtagene autoleucel (cilta-cel), another BCMA-directed CAR-T cell therapy, reported that true EMD was associated with a significantly lower ORR, as well as shorter PFS and OS, compared to non-EMD patients[17]. Nevertheless, the results were promising compared to historical EMD cohorts.”
