Patient baseline characteristics before CAR-T infusion.
ANC, absolute neutrophil count; ASCT, autologous stem cell transplantation; IMiD, immunomodulatory drug; PI, proteasome inhibitor.
High-risk cytogenetics include t(4;14), t(14;16), t(14;20), and/or del(17p). Triple-drug refractory disease indicates refractory to an IMiD, PI, and daratumumab; penta-drug refractory indicates refractory to lenalidomide, pomalidomide, bortezomib, carfilzomib, and daratumumab.
