What was measured

Duration of response was measured for participants in remission (CR/CRh\*), and was measured from the time the participant first achieved remission until first documented relapse or death from disease progression. Participants without a documented relapse (hematological or extramedullary) and who did not die were censored at the time of the last bone marrow assessment or the last survival follow-up visit to confirm remission. Participants who died without having reported hematological relapse or without showing any clinical sign of disease progression were censored on their date of death.

Analysis population: Participants who received an infusion of blinatumomab and with a CR or CRh\* response during the first 2 treatment cycles.

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 2 cycles. Participants who achieved a complete remission or complete remission with partial or incomplete hematologic recovery within 2 induction cycles of treatment could receive up to 3 additional consolidation cycles of blinatumomab. The initial dose was 9 μg/day for the first 7 days of treatment, increased to 28 μg/day starting on day 8 and for all subsequent cycles of treatment.
