Design outcomes

Primary

MeasureTime frame
The identification and documentation of long-term adverse effects following genome-edited allogeneic universal CAR T cell therapy and allogeneic transplant (PBLTT52CAR19, BE-CAR7, and BE-CAR33), including non-persistence of IMP beyond allo-SCT (via chimerism testing), the occurrence of new haematologic disorders (cytopenia, malignancies), autoimmune disorders, immune recovery (T-cell, B-cell aplasia, immunoglobulins), severe viral infections, engraftment, chimerism status, and new or ongoing GVHD grade 3 or higher, assessed annually from year 2 or 3 through year 15 (+/- 1 month)

Secondary

MeasureTime frame
The tracking of mononuclear cell chimerism for the recipient, transplant donor, and IMP (CAR-T) donor signals to confirm the non-persistence of IMP (by chimerism assay). Chimerism status in blood will be performed annually from year 2 or 3 through year 15 (+/- 1 month)
