Groups in this outcome

Phase 1: Blinatumomab 5 µg/m²/Day

Blinatumomab was administered as a continuous intravenous (cIV) infusion at a constant daily flow rate of 5 µg/m²/day over 4 weeks followed by a treatment-free interval of 2 weeks for up to five cycles of treatment.

Phase 1: Blinatumomab 15 µg/m²/Day

Blinatumomab was administered as a continuous intravenous infusion at a constant daily flow rate of 15 µg/m²/day over 4 weeks followed by a treatment-free interval of 2 weeks for up to five cycles of treatment.

Phase 1: Blinatumomab 30 µg/m²/Day

Blinatumomab was administered as a continuous intravenous infusion at a constant daily flow rate of 30 µg/m²/day over 4 weeks followed by a treatment-free interval of 2 weeks for up to five cycles of treatment.

Phase 1: Blinatumomab 15/30 µg/m²/Day

Blinatumomab was administered as a continuous intravenous infusion at a constant daily flow rate of 15 µg/m²/day for the first week of cycle 1 and then at 30 µg/m²/day for 3 weeks followed by a treatment-free interval of 2 weeks. Participants received subsequent cycles at 30 µg/m²/day for up to five cycles of treatment.

Phase 1: Blinatumomab 5/15 µg/m²/Day

Blinatumomab was administered as a continuous intravenous infusion at a constant daily flow rate of 5 µg/m²/day for the first week of cycle 1 and then at 15 µg/m²/day for 3 weeks followed by a treatment-free interval of 2 weeks. Participants received subsequent cycles at 15 µg/m²/day for up to five cycles of treatment.

Phase 2: Blinatumomab 5/15 µg/m²/Day

Blinatumomab was administered as a continuous intravenous infusion at a constant daily flow rate of 5 µg/m²/day for the first week of cycle 1 and then at 15 µg/m²/day for 3 weeks followed by a treatment-free interval of 2 weeks. Participants received subsequent cycles at 15 µg/m²/day for up to five cycles of treatment.

Phase 1+2: Blinatumomab 5/15 µg/m²/Day

Blinatumomab was administered as a continuous intravenous infusion at a constant daily flow rate of 5 µg/m²/ day for the first week of cycle 1 and then at 15 µg/m²/day for 3 weeks followed by a treatment-free interval of 2 weeks. Participants received subsequent cycles at 15 µg/m²/day for up to five cycles of treatment.
