Experimental: Blinatumomab Treatment
Eligible patients with detectable MRD will taper immunosuppressive medications, if applicable, and undergo treatment with blinatumomab. The duration of each cycle of blinatumomab treatment is 6 weeks. Adult and pediatric patients will be treated for 4 weeks followed by a 2-week treatment free period. Patients may receive up to 4 cycles total of blinatumomab therapy.
Continuous intravenous infusion
- MRD Response [ Time Frame: Following 1st cycle of blinatumomab (each cycle is 28 days) ]To determine the proportion of patients with MRD response, defined as negative MRD as measured by flow cytometry, after 1 cycle of blinatumomab.
- Safety and Tolerability [ Time Frame: During Blinatumomab treatment, an average of 24 weeks ]Safety of delivering blinatumomab will be monitored early during the post-transplant course. Safety will be evaluated by the onset of treatment emergent adverse events (TEAEs) and by documentation of the incidence and severity of acute and chronic graft versus host disease (GvHD).
- Survival [ Time Frame: Up to 5 years ]Clinically relevant survival outcomes for patients enrolled onto the study including: 2-year and 5-year overall survival (OS) and event free-survival (EFS) and median OS.
- Incidence of MRD Post HSCT [ Time Frame: Up to day +270 following stem cell transplant ]To determine the proportion of patients developing detectable MRD following HSCT for B-ALL as measured by flow cytometry.
- Patient Recruitment (Number of Patients Recruited) [ Time Frame: Through Study Completion, an average of 2 years ]Feasibility
- Turnaround time of centralized MRD testing (days) [ Time Frame: Through Study Completion, an average of 2 years ]Feasibility
- Time to delivery of blinatumomab following MRD detection [ Time Frame: Through Study Completion, an average of 2 years ]Feasibility
