Clinical Trial Summary

This phase III trial compares the effect of the combination of blinatumomab with dasatinib and standard chemotherapy versus dasatinib and standard chemotherapy for treating patients with Philadelphia chromosome positive (PH+) or Philadelphia chromosome-like (Ph-Like) ABL-class B-Cell acute lymphoblastic leukemia (B-ALL). Blinatumomab is a bispecific antibody that binds to two different proteins-one on the surface of cancer cells and one on the surface of cells in the immune system. An antibody is a protein made by the immune system to help fight infections and other harmful processes/cells/molecules. Blinatumomab may bind to the cancer cell and a T cell (which plays a key role in the immune system's fighting response) at the same time. Blinatumomab may strengthen the immune system's ability to fight cancer cells by activating the body's own immune cells to destroy the tumor. Dasatinib is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply, which may help keep cancer cells from growing. Giving blinatumomab and dasatinib in combination with standard chemotherapy may work better in treating patients with PH+ or Ph-Like ABL-class B-ALL compared to dasatinib and chemotherapy alone.


Description:

PRIMARY OBJECTIVE: I. To compare the 4-year event free survival (EFS) of children, adolescents, and young adults with Ph+ (BCR:ABL1-rearranged) and Ph-like ABL-class B- ALL who are randomized post-Induction to receive continuous dasatinib and the modified augmented Berlin-Frankfurt-Munster (mBFM) chemotherapy backbone (Arm A) versus continuous dasatinib and a chemotherapy backbone that incorporates three cycles of blinatumomab (Arm B) without traditional consolidation chemotherapy. SECONDARY OBJECTIVES: I. To compare the 4-year and long-term overall survival (OS) of all patients with Ph+ and Ph-like ABL-class B-ALL between randomized arms. I. To compare post-induction/pre-maintenance toxicities (infections, mucositis, neurotoxicity, cytokine release syndrome, therapy delays > 14 days, and treatment-related mortality) between patients on the randomized study arms. I. To compare end of consolidation (EOC)/timepoint 2 (TP2) minimal residual disease (MRD) negativity at the 1x10^-4 or 0.01% threshold between patients on the randomized study arms. EXPLORATORY OBJECTIVES: I. To describe rates of end of induction (EOI)/timepoint 1 (TP1) bone marrow MRD negativity with the introduction of dasatinib by induction day 15 for Ph+ and Ph-like ABL-class B-ALL patients as a whole cohort and as separate groups. II. To describe EFS, disease-free survival (DFS), and overall survival (OS) of Ph+ and Ph-like ABL-class B-ALL patients separately and compared to historical controls. III. To describe the outcomes of patients with Ph+ and Ph-like ABL-class B-ALL who are removed from protocol therapy due to consolidation failure. IV. To describe the percentage of patients with Ph+ and Ph-like ABL-class B-ALL who continue tyrosine kinase inhibitors (TKI) beyond protocol-prescribed therapy and their outcomes. V. To describe the prognostic significance of MRD by next-generation sequencing (NGS) at end of induction and end of consolidation. VI. To describe the clinical characteristics and outcomes of patients with chronic myeloid leukemia (CML)-like biology. VII. To describe the immune function of Ph+ and Ph-like ABL-class B-ALL patients between the two randomized arms and correlate with treatment response. VIII. To describe the dasatinib levels in the plasma and cerebrospinal fluid of children with Ph+ and Ph-like ABL-class B-ALL and correlate with outcome. IX. To describe the impact of dasatinib and high-dose methotrexate interaction and identify clinical and biologic factors influencing methotrexate clearance.
