Brief Summary:
The primary objective was to evaluate the effect of blinatumomab on overall survival when compared to standard of care (SOC) chemotherapy.
Detailed Description:
Adults with relapsed/refractory B-cell precursor ALL were randomized in a 2:1 ratio to receive blinatumomab or 1 of 4 pre-specified, investigator-chosen, SOC chemotherapy regimens. Randomization was stratified by age (\< 35 years vs ≥ 35 years of age), prior salvage therapy (yes vs no), and prior allogeneic HSCT (yes vs no) as assessed at the time of consent.
The study consisted of up to a 3-week screening and pre-phase period, a treatment period consisting of induction with 2 cycles of either blinatumomab or SOC chemotherapy, a consolidation phase of up to 3 additional cycles of protocol-specified therapy, and a maintenance phase for up to an additional 12 months with protocol-specified therapy. A safety follow-up visit 30 days after the last dose of protocol-specified therapy and a long-term follow-up period were included. The long-term follow-up part of the study was discontinued prematurely based on a recommendation from the data monitoring committee (DMC) that the study be stopped for benefit.
