简要总结

This randomized phase III trial studies how well blinatumomab works compared with standard combination chemotherapy in treating patients with B-cell acute lymphoblastic leukemia that has returned after a period of improvement (relapsed). Immunotherapy with blinatumomab may allow the body's immune system to attack and destroy some types of leukemia cells. It is not yet known whether blinatumomab is more effective than standard combination chemotherapy in treating relapsed B-cell acute lymphoblastic leukemia.

详细描述

PRIMARY OBJECTIVES: I. To compare disease free survival (DFS) of high-risk (HR) and intermediate-risk (IR) relapse B-cell acute lymphoblastic leukemia (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) as a part of a treatment regimen prior to allogeneic bone marrow transplantation. (Closed to enrollment effective September 18, 2019) II. To compare the DFS of low risk (LR) relapse B-ALL patients who are randomized following block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR randomization). (Closed to enrollment effective September 30, 2019) SECONDARY OBJECTIVES: I. 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). (Closed to enrollment effective September 18, 2019) II. 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). EXPLORATORY OBJECTIVES: I. To compare the rates of minimal residual disease (MRD) \>= 0.01% at the end of block 2 and block 3 for HR and IR relapse B-ALL patients in HR/IR randomization. II. 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. III. 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). IV. To evaluate blinatumomab pharmacokinetics (PK) and explore exposure-response relationships for measures of safety and effectiveness. OUTLINE: All patients receive Block 1 over 4 weeks. BLOCK 1: Patients receive dexamethasone orally (PO) twice daily (BID) or intravenously (IV) on days 1-5 and 15-19; vincristine sulfate IV over 1 minute on days 1, 8, 15, and 22; pegaspargase IV over 1-2 hours on days 3 and 17; mitoxantrone hydrochloride IV over 15-30 minutes on days 1-2, and methotrexate intrathecally (IT) on day 1.

时间窗: Up to 2 years from date of randomization

DFS rates 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). DFS is calculated as the time from randomization to date of first event (treatment failure, relapse, second malignancy, remission death) or date of last contact. Two-year DFS estimates will be calculated from date of randomization for both Arm A and Arm B. Two-sided 95% confidence intervals will be calculated.

时间窗: Up to 3 years from date of randomization

DFS rates of LR relapse B-ALL patients who are randomized following Block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR Randomization). DFS is calculated as the time from randomization to date of first event (relapse, second malignancy, remission death) or date of last contact. Three-year DFS estimates will be calculated from date of randomization for both Arm C and Arm D. Two-sided 95% confidence intervals will be calculated.
