Real-world outcomes for multiple myeloma patients after apheresis for planned chimeric antigen receptor T-cell therapy

Background

Chimeric antigen receptor T-cell (CAR-T) therapy is highly active in relapsed/refractory multiple myeloma (RRMM), but manufacturing creates an obligatory waiting period between apheresis and infusion. Patients may deteriorate, progress or die during this window. Analyses that begin follow-up at infusion exclude these patients entirely and cannot describe the experience of all patients who enter the CAR-T pathway.
