Study Arms:
- Blinatumomab (Type: EXPERIMENTAL): Treatment consisted of two induction cycles and up to 3 consolidation cycles of treatment for responders.~In the first induction cycle, the initial dose of blinatumomab was 9 μg/day for Days 1-7 and then escalated (dose step) to 28 μg/day starting on day 8 (week 2) through day 29 (week 4). This is followed by two weeks without blinatumomab treatment.~In subsequent cycles (beginning with the second induction cycle and continuing through consolidation, for applicable participants) 28 μg/day was administered for all 4 weeks of continuous treatment, followed by a treatment-free interval of two weeks.

Based on this trial design, predict the completion outcome and termination type (if applicable).
