To compare disease free survival (DFS) of HR and IR relapse B-ALL patients who are randomized following Induction Block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR Randomization).
To compare DFS of LR relapse B-ALL patients who are randomized following Block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR Randomization).
To compare overall survival (OS) of HR and IR relapse B-ALL patients who are randomized following Induction Block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5 week blocks of blinatumomab (HR/IR Randomization).
To compare OS of LR relapse B-ALL patients who are randomized following Block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR Randomization
To compare the rates of MRD ≥ 0.01% at the end of Block 2 and Block 3 for HR and IR relapse B-ALL patients in HR/IR randomization.
To estimate, for treatment failure (TF) patients not previously receiving blinatumomab, the hematologic complete remission rate (CR), rate of MRD < 0.01%, and proportion able to proceed to hematopoietic stem cell transplant (HSCT) in CR after treatment with blinatumomab.
To assess the feasibility and safety of rapid taper of immune suppression for the subset of HSCT patients with MRD ≥ 0.01% pre- and/or post-HSCT with no acute graft versus host disease (aGVHD).
To evaluate blinatumomab pharmacokinetics (PK) and explore exposure-response relationships for measures of safety and effectiveness.
Patients ≥1 year and < 31 years of age at the time of relapse will be eligible.
First relapse of B-ALL, allowable sites of disease include
isolated bone marrow, combined bone marrow and CNS
and/or testicular, and isolated CNS and/or testicular.
Extramedullary sites are limited to the CNS and testicles.
Please refer to Section 3.3 for definitions of relapse and
criteria for risk classification.
Review- concomitant therapy restrictions for patients during
No waiting period for patients who relapse while receiving
standard Maintenance therapy
Patients who relapse on frontline therapy in phases other than
Maintenance must have fully recovered from the acute toxic
effects of all prior chemotherapy, immunotherapy, or
radiotherapy prior to entering this study.
Cytotoxic therapy: At least 14 days since the completion of
cytotoxic therapy with the exception of hydroxyurea, which is
permitted up to 24 hours prior to the start of protocol therapy, .
Biologic (anti-neoplastic) agent: At least 7 days since the
completion of therapy with a biologic agent. For agents that
have known adverse events occurring beyond 7 days after
administration, this period must be extended beyond the time
during which adverse events are known to occur.
Stem cell transplant or rescue: Patient 184.108.40.206 Stem cell
transplant or rescue: Patient has not had a prior stem cell
transplant or rescue.
Patient has not had prior treatment with blinatumomab.
With the exception of intrathecal chemotherapy (methotrexate
strongly preferred) administered at the time of the required
diagnostic lumbar puncture to establish baseline CNS status,
patient has not received prior relapse-directed therapy (i.e.,
this protocol is intended as the INITIAL treatment of first
Patients must have a performance status corresponding to
ECOG scores of 0, 1, or 2. Use Karnofsky for patients > 16
years of age and Lansky for patients ≤ 16 years of age.
