Primary Outcome Measures:
  • To determine the maximum tolerated doses and dose-limiting toxicities (DLTs) of nelarabine, etoposide and cyclophosphamide when given in combination to children with T-ALL and bone marrow relapse or T-LL. [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • To determine the complete remission rate after 1 and 2 courses of this therapy in children with T-ALL and bone marrow relapse or T-LL. [ Time Frame: 1-3 months ]
  • To determine the percent of children with T-ALL and 1st BM relapse that have a complete response after therapy on this study and proceed to stem cell transplantation in complete response within 20 weeks of beginning this regimen. [ Time Frame: 5 months ]
  • To determine minimal residual disease (MRD) levels at the end of each course of treatment. [ Time Frame: 60 days ]
  • To evaluate the vitamin B12 pathway and metabolites and the potential association of neurotoxicity following nelarabine therapy with alterations in this pathway. [ Time Frame: 3 years ]
  • To determine, in a preliminary manner, whether patients with relapsed T-ALL/LL have a distinct signaling signature that distinguishes malignant cells from normal thymocytes. [ Time Frame: 3 years ]
  • To evaluate, in a preliminary manner, whether phospho-flow cytometry can be used to predict clinical response to Nelarabine. [ Time Frame: 3 years ]

Inclusion Criteria:

  • Patients to be enrolled in the dose-escalation portion of this study must have T-cell ALL or T-cell lymphoblastic lymphoma (LL) in first relapse or must have failed primary induction chemotherapy (ie, never attained a complete remission following an initial course of standard therapy for T-ALL or T-LL). Patients to be enrolled in the cohort expansion portion of this study (ie, those treated at the recommended phase 2 dose) must have T-cell ALL in first relapse or must have failed primary induction chemotherapy (ie, never attained a complete remission following an initial course of standard therapy for T-ALL). T-LL patients are not eligible for the cohort expansion phase.
  • Patients with T-cell ALL must have greater than 25% blasts in the bone marrow with or without extramedullary disease.
  • Patients with T-cell LL must have recurrent disease, documented by clinical or radiographic criteria, as well as histologic verification of the malignancy at original diagnosis. Patients with T-cell LL enrolled in the phase I dose-escalation study are not required to have measurable disease; however, patients enrolled in the phase II cohort expansion at the MTD must have measurable disease.
  • Patients may have CNS 1 or CNS 2 disease but not CNS 3.
  • ECOG 0-2 or Karnofsky ≥ 50% for patients > 16 years of age; Lansky ≥ 50% for patients ≤16 years of age.
  • Patients may be enrolled on study regardless of the timing of prior Intrathecal therapy; however, they MAY NOT BEGIN TREATMENT ON THIS PROTOCOL UNTIL A MINIMUM OF 7 DAYS HAS ELAPSED SINCE PRIOR INTRATHECAL THERAPY.
  • At least 6 weeks must have elapsed since administration of nitrosureas.
  • At least 12 weeks must have elapsed since administration of craniospinal or hemipelvic radiation.

  • Total bilirubin ≤ 1.5x ULN for age. If the total bilirubin is elevated, patient will still be eligible if the conjugated (direct) serum bilirubin ≤ ULN for age.

  • Adequate cardiac function defined as shortening fraction of ≥ 27% by echocardiogram or ejection fraction ≥ 45% by gated radionuclide study.
  • No evidence of dyspnea at rest
  • No exercise intolerance
  • A pulse oximetry ≥ 94% at sea level (≥ 90% at altitude ≥ 5000 feet) if there is clinical indication for determination.
