Study Summary

The researchers are doing this study to find out whether PK-targeted fludarabine is an effective Lymphodepletion (LD) chemotherapy approach for people with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) who will receive tisagenlecleucel CAR T-cell therapy. The researchers will compare PK-targeted fludarabine dosing with standard fludarabine dosing to see which treatment approach is more effective. The researchers will also look at whether PK-targeted fludarabine dosing is feasible (practical), the side effects of the study treatment, and how the study treatment affects people's quality of life. The researchers will measure quality of life by having participants complete questionnaires.

Primary Outcome

EFS is defined as time from randomization until non-response at day 28 after CAR T cell infusion, loss of B-cell aplasia \<6 months from the time of CAR T cell infusion, disease relapse, initiation of anti-leukemic therapy or death of any cause
