Brief Summary: The primary objective is to estimate the overall event-free survival of children at least one year of age at diagnosis who are treated with risk-directed therapy and to monitor the molecular remission induction rate
Detailed Description: These are the following secondary objectives

To determine if CNS irradiation can be safely omitted in the context of the systemic therapy used in the protocol
To identify whether prolonged 24 hour intravenous infusions of HDMTX produce greater methotrexate polyglutamate MTXPG accumulation than short 4 hour infusions 42 hours after 1 gmm2 of HDMTX stratified for lineage T- vs B-lineage and ploidy hyperdiploid vs non-hyperdiploid B-lineage
To determine whether prolonged 24 hour intravenous infusions of HDMTX produce greater antileukemic effects than short 4 hour infusions based on the inhibition of de novo purine synthesis in bone marrow blasts and the decrease in circulating blasts during the 4 day window prior to initiation of conventional remission induction therapy

Details of Treatment Plan

Treatment will consist of three main phases Remission Induction Consolidation and Continuation Treatment with an Upfront HDMTX Window for research purposes will be optional

All patients will receive IT therapy on day 1 dose is age dependent

Upfront High-Dose Methotrexate Window

HDMTX 1 gm2 as a 4 hour infusion versus as a 24 hour infusion Leucovorin rescue will be given

Remission Induction

Prednisone 40 mgm2day PO Days 5 - 32 Vincristine 15 mgm2week IV Days 5 12 19 26 Daunorubicin 25 mgm2week IV Days 5 12 L-asparaginase 10000 Unitm2dose IM Days 6 8 10 12 14 16 19 21 23 Cyclophosphamide 1000 mgm2dose IV Day 26 Cytarabine 75 mgm2dose IV Days 27-30 34-37 6-Mercaptopurine 60 mgm2dose PO Days 26-39 Imatinib 40 mgm2 bid for Ph positive patients starting Day 22 of induction Intrathecal therapy will be administered on day 1 and 19 dose age dependent Patients with high risk of CNS relapse will receive additional IT treatments on days 8 and 26

Consolidation Treatment

High dose methotrexate targeted dose depending on risk status days 1 15 29 and 43 and mercaptopurine 50 mgm2day days 1-56

Reintensification treatment for patients with high risk disease

Patients with high risk disease will be offered the option of hematopoietic stem cell transplant HSCT and may receive an additional 1-2 cycles of reintensification treatment prior to maximize the anti-leukemic kill before transplant

Dexamethasone 20 mgm2 PO days 1-3 Cytarabine 2 gm2 IV x 4 doses days 3-5 Etoposide 100 mgm2 IV x 5 doses days 3-5 L-asparaginase 25000 Unitsm2 IM day 6 Intrathecal treatment Day 5

Continuation Treatment lasts 120 weeks for girls and 146 weeks for boys

Treatment will depend on risk classification low versus standard versus high risk

The same treatment weeks 21-28 will be repeated for a total of 6 times until week 68 After week 68 all patients will receive daily 6MP and weekly MTX with pulses of dexamethasone and vincristine every 4 weeks until week 100 after which only 6MP and methotrexate will be given Intrathecal treatment will be given every 8 weeks only to patients at high risk of CNS relapse after week 48 and will be discontinued after week 96 Continuation therapy will be discontinued after 120 weeks in girls and after 146 weeks in boys

Patients who meet the criteria of high-risk ALL are candidates for allogeneic hematopoietic stem cell transplantation However if the option is declined by the patients or guardians or the procedure is deemed unsuitable by the attending physician and the principal investigator the patient will remain on study and continue to receive chemotherapy
