PRIMARY OBJECTIVES: I. To estimate the 3-year event-free survival (EFS) of infants with mixed lineage leukemia-rearranged (MLL-R) acute lymphoblastic leukemia (ALL) treated with chemotherapy plus the fms-related tyrosine kinase 3 (FLT3) inhibitor lestaurtinib. SECONDARY OBJECTIVES: I. To compare the 3-year EFS of infants with MLL-R ALL treated with chemotherapy plus the FLT3 inhibitor lestaurtinib to MLL-R patients treated with chemotherapy alone. II. To determine a safe, tolerable and biologically active dose of lestaurtinib given in sequential combination with chemotherapy in MLL-R infants. III. To characterize the pharmacokinetics and pharmacodynamics of lestaurtinib in infants when given at the proposed dose in sequential combination with chemotherapy. IV. To identify molecular mechanisms of resistance to lestaurtinib in leukemic blasts. V. To describe levels of minimal residual disease in infants with ALL within the context of the proposed therapy, and correlate with outcome. VI. To identify gene expression patterns in diagnostic infant leukemia samples that correlate with outcome within the context of the proposed therapy. VII. To describe the outcome of infants with MLL-G ALL treated with a modified P9407 chemotherapy backbone that includes an extended continuation phase.
