Late leukapheresis (>6 months after CAR19) resulted in less residual CAR19, higher CAR22 CD4+ naïve T and TCM cells, less TEM cells, and higher CD8+ TCM cells, but similar clinical outcomes to those with early leukapheresis. CAR22 responses were associated with higher transduction efficiency and CD8+ TCM and less CD8+ TEM cells.
