Summary

This randomized phase III trial is studying different combination chemotherapy regimens and comparing how well they work in treating patients with newly diagnosed acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.

Principal investigator Kelly Maloney, MD
Description PRIMARY OBJECTIVES: I. To determine whether the substitution of three intensified phases of post-Induction treatment for standard phases will improve the event free survival (EFS) of children with SR-average acute lymphoblastic leukemia (ALL). II. Determine whether the substitution of intensified Consolidation for standard Consolidation will improve the EFS of children with SR-average ALL. III. To determine whether the addition of four doses of percutaneous endoscopic gastrostomy (PEG) asparaginase, given once every three weeks during Consolidation and Interim Maintenance phases, will improve the EFS for children with SR-low ALL. SECONDARY OBJECTIVES: I. Identify potentially modifiable factors associated with impaired health related quality of life (HRQOL) at different periods of therapy in the patients who are SR-average enrolled on the standard risk ALL study. II. Determine the critical time periods when future intervention studies to mitigate adverse HRQOL outcomes should occur. III. Correlate day 29 minimal residual disease (MRD) with EFS and overall survival (OS) of patients treated with these regimens. IV. Correlate early marrow response with day 29 MRD status. V. To improve outcome by identifying additional high risk patients by Day 29 MRD for treatment with fully augmented Berlin-Frankfurt-Munster (BFM). VI. To examine the relative contributions of genetic factors and early treatment response to outcome by comparing the outcome of patients with and without TEL-AML1 fusion or triple trisomy and low levels of MRD at end Induction who are treated with identical therapy on the standard arms of the SR-low and SR-average trials. OUTLINE: This is a 2-part, partially randomized, multicenter study. Patients are stratified according to early response to study induction therapy (rapid early response [standard risk (SR)-low or SR-average acute lymphoblastic leukemia (ALL)] vs slow early response [SR-high ALL]). After completion of induction therapy but before proceeding to part II therapy, patients are assigned to 1 of 3 groups based on stratification.

Patients with Down syndrome (DS) receive leucovorin calcium PO at 48 and 60 hours after each dose of methotrexate IT. Patients are assessed for response on day 29. Patients with M1 bone marrow AND minimal residual disease (MRD) < 0.1% OR MRD >= 0.1% and < 1% proceed to therapy in part II.
