AALL1631: International Phase 3 trial in Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) testing imatinib in combination with two different cytotoxic chemotherapy backbones
Why are we doing this research?
BRIEF SUMMARY:
This randomized phase III trial studies how well imatinib mesylate and combination chemotherapy work in treating patients with newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukemia. Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving imatinib mesylate and combination chemotherapy may work better in treating patients with Philadelphia chromosome positive acute lymphoblastic leukemia.
DETAILED DESCRIPTION:
PRIMARY OBJECTIVES:
- To compare disease-free survival (DFS) of standard risk pediatric Philadelphia chromosome (Ph)+ acute lymphoblastic leukemia (ALL) treated with continuous imatinib mesylate (imatinib) combined with either a high-risk Children's Oncology Group (COG)/Berlin-Frankfurt-Munster (BFM) ALL chemotherapy backbone or the more intensive European (Es)PhALL chemotherapy backbone.
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Who can participate?
AGES ELIGIBLE FOR STUDY: 2 years to 21 Years
ELIGIBILITY CRITERIA
Inclusion Criteria:
- Patients who have not previously enrolled on AALL08B1 or APEC14B1 (if open for classification of newly diagnosed ALL patients) prior to enrollment on AALL1631, a baseline diagnostic sample must be available to develop an MRD probe
- Newly diagnosed de novo ALL (B-ALL or T-ALL) with definitive evidence of BCR-ABL1 fusion by karyotype, fluorescence in situ hybridization (FISH) and/or reverse transcriptase (RT)-PCR
- For patients who DO NOT enter AALL1631 via AALL08B1 or APEC14B1 (if open for classification of newly diagnosed ALL patients), laboratory reports detailing evidence of BCR-ABL1 fusion must be submitted for rapid central review within 72 hours of study enrollment
- Patients with known chronic myelogenous leukemia (CML) who develop lymphoid blast crisis are not eligible
- Patient must have previously started induction therapy, which includes vincristine, a corticosteroid, pegaspargase, with or without anthracycline, and/or other standard cytotoxic chemotherapy
- Patient has not received more than 14 days of induction therapy
- Patient has not had prior treatment with imatinib, dasatinib, or any other BCR-ABL1 inhibitor
Exclusion Criteria:
