Study Arms:
- Blinatumomab (Type: EXPERIMENTAL): Blinatumomab was administered as a continuous intravenous (cIV) infusion at a constant daily flow rate over 4 weeks followed by a treatment-free interval of 2 weeks. Doses ranged between 5 and 30 µg/m²/day. Each participant received up to five cycles of treatment.
