Descrição detalhada
PRIMARY OBJECTIVES:
I. To assess the feasibility and safety of using an intensified sequential induction regimen to treat children with acute lymphoblastic leukemia (ALL), who experience an isolated, or combined bone marrow relapse.
II. To determine the potential of this regimen to serve, as a backbone, for the future testing of novel therapeutic agents.
SECONDARY OBJECTIVES:
I. To estimate the remission re-induction rates and four-month event-free survival (EFS) for children, stratified by the duration of first remission.
II. To determine the feasibility of measuring minimal residual disease (MRD) quantitatively in all patients at time points throughout re-induction, and to correlate post-remission events with disease burden during induction.
III. To use deoxyribonucleic acid (DNA) arrays to characterize patterns of gene expression that predict treatment failure, and to compare gene expression profiles at the time of relapse with those at the time of initial diagnosis to gain an understanding of the pathways that may be involved in disease recurrence.
IV. To determine the feasibility of combining intensive re-induction therapy with imatinib mesylate (STI571) for children with a relapse of Philadelphia chromosome positive (Ph+) ALL.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I:
Treatment Block 1: Patients receive cytarabine intrathecally (IT) on day 1 and methotrexate IT on days 15 and 29. Patients also receive vincristine intravenously (IV) on days 1, 8, 15, and 22; prednisone orally (PO) twice or thrice daily (BID or TID) on days 1-29; pegaspargase intramuscularly (IM) on days 2, 8, 15, and 22; and doxorubicin IV over 15 minutes on day 1. Ph-positive patients also receive imatinib mesylate PO on days 1-14.
Treatment Block 2: Patients receive methotrexate IT on days 1 and 22, cyclophosphamide IV over 30 minutes and etoposide IV over 2 hours on days 1-5, and filgrastim (G-CSF) subcutaneously (SC) beginning on day 6 and continuing until blood counts recover. Patients also receive methotrexate IV over 24 hours on day 22 followed by leucovorin calcium IV every 6 hours on days 24 and 25. Ph-positive patients receive imatinib mesylate PO on days 1-14.
Treatment Block 3a (Ph-negative patients): Patients receive cytarabine IV over 3 hours every 12 hours on days 1, 2, 8, and 9, asparaginase IM on days 2 and 9, and G-CSF SC beginning on day 10 and continuing until blood counts recover.
Treatment Block 3b (Ph-positive patients): Patients receive cytarabine IV over 3 hours every 12 hours on days 1 and 2, asparaginase IM on day 2, and G-CSF SC beginning on day 3 and continuing until blood counts recover. Patients also receive imatinib mesylate PO on days 1-14.
ARM II:
Treatment Block 1: Patients receive cytarabine IT on day 1 and then methotrexate, cytarabine and hydrocortisone IT (triple intrathecal therapy; TIT) on days 8, 15, 22, and 29. Vincristine, prednisone, pegaspargase, doxorubicin, and imatinib mesylate are administered as in arm I.
Treatment Block 3: Patients receive cytarabine, asparaginase, G-CSF, and imatinib mesylate as in arm I.
Treatment Block 2: Patients receive TIT on days 1 and 22. Patients then receive cyclophosphamide, etoposide, G-CSF, methotrexate IV, leucovorin calcium, and imatinib mesylate as in arm I. After each block is completed, disease is assessed. The next block is started on day 36 if blood counts have recovered and marrow during block 1 is at least M2/M3. Patients are removed from protocol therapy if disease progresses, unacceptable toxicity occurs, marrow is M2/M3 at day 15 of the second administered block of treatment, or cerebrospinal fluid blasts persist after 6 weekly doses of TIT.
After completion of study treatment, patients are followed up for 4 months.
PROJECTED ACCRUAL: A total of 63-126 patients will be accrued for this study within 14 months.

Descrição
Inclusion Criteria:
- Patients with acute lymphoblastic leukemia (ALL) in first relapse involving the bone marrow (M3 marrow), with or without associated extramedullary disease; this includes patients who are Philadelphia chromosome-positive
- Shortening fraction of >= 28% by echocardiogram, or ejection fraction of >= 50% by gated radionuclide study
- Cumulative prior anthracycline exposure of =< 350 mg/m^2 (each 10 mg/m^2 dose of idarubicin should be calculated as the isotoxic equivalent of 50 mg/m^2 of daunorubicin or adriamycin)
- All patients and/or their parents or legal guardians must sign a written informed consent
- All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met
Exclusion Criteria:
- Patients with B-cell ALL (L3 morphology or evidence of myc translocation by molecular or cytogenetic technique) are not eligible
- Patients with Down syndrome are excluded due to the administration of methotrexate in Block 2
Patients who have undergone prior stem cell transplantation (SCT) are ineligible if:
- They received SCT less than 12 months prior to study entry
- They are still receiving immunosuppression for the treatment of graft-versus-host disease (GVHD)
- They have active fungal infection at time of study entry
- They have had invasive filamentous fungal infection at any time post-SCT
- Pregnant or lactating females are ineligible as the medications used in this protocol could be harmful to unborn children and infants
- Patients with prior isolated extramedullary relapse are ineligible
