What was measured

Hematological assessments were performed from bone marrow biopsy samples. All hematological assessments of bone marrow were reviewed in a central reference laboratory. Hematological remissions were defined by the following criteria: Complete Remission (CR): * bone marrow blasts ≤ 5% * no evidence of disease * full recovery of peripheral blood counts: * platelets \> 100,000/μL, and * absolute neutrophil count (ANC) \> 1,000/μL Complete Remission With Partial Hematological Recovery (CRh\*): * bone marrow blasts ≤ 5% * no evidence of disease * partial recovery of peripheral blood counts: * platelets \> 50,000/μL, and * ANC \> 500/μL.

Analysis population: The Primary Analysis Set (PAS), defined as participants from the first 3 stages of the study who received any infusion of blinatumomab.

Groups in this outcome

Blinatumomab

Participants received blinatumomab by continuous intravenous (CIV) infusion over 4 weeks followed by a treatment-free interval of 2 weeks for up to 5 consecutive cycles. The initial dose was 9 μg/day for the first seven days of treatment, escalated to 28 μg/day starting from Week 2 of treatment.
