What was measured

Hematological RFS was measured from first dose of blinatumomab until the first assessment of documented relapse (either hematological or extramedullary), secondary leukemia, or death due to any cause. Participants without a documented relapse, or death due to any cause were censored at the time of their last hematological assessment. Participants who received chemotherapy for relapsed or persistent MRD or for any other reason after treatment with blinatumomab, or HSCT after treatment with blinatumomab, before hematological or extramedullary relapse, or death occurred were censored at the start of chemotherapy or HSCT, respectively. Hematological relapse was defined as unequivocal detection of \> 5% leukemia cells in bone marrow as measured by cytological, microscopic assessment, presence of circulating leukemia blasts, or extramedullary leukemia (whichever occurred first). The 18-month Kaplan-Meier estimate of hematological RFS is reported.

Analysis population: Full analysis set participants who were in hematological complete remission at treatment start, excluding Philadelphia-positive participants.
