Brief summary

Nelarabine has shown significant activity in patients with T-cell malignancies. This study will determine the safety and maximum tolerated dose of the combination of nelarabine, cyclophosphamide and etoposide in patients with first bone marrow relapse of T-ALL, or first relapse of T-LL.

Interventions

DRUGNelarabine

Dose will be assigned at study entry. Nelarabine will be given IV over 60 minutes (given at hours 0 to 1) on days 1 through 5.

DRUGEtoposide

100 mg/m2/day IV over 2 hours (given at hours 1 to 3) on days 1 through 5

DRUGCyclophosphamide

Dose will be assigned at study entry, IV as a 30-60 minute infusion (given at hours 3 to 4) on days 1 through 5.

DRUGMethotrexate

Give between day 29 and 36 or when ANC\>750 and PLTS\>75,000 - whichever comes first (but not prior to day 22) at the dose defined by age below, ideally in conjunction with BM evaluation. Given intrathecally at the dose defined by age below. 8 mg for patients age greater than or equal to 1, but \<2 years of age 10 mg for patients age greater than or equal to 2, but \<3 years of age 12 mg for patients greater than or equal to 3, but \< 9 years of age 15 mg for patients greater than or equal to \>9 years of age

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).

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. * Female patients of childbearing potential must have a negative urine or serum pregnancy test confirmed within 2 weeks prior to enrollment. * Female patients with infants must agree not to breastfeed their infants while on this study. * Male and female patients of child-bearing potential must agree to use an effective method of contraception approved by the investigator during the study and for a minimum of 6 months after study treatment. * Adequate renal function defined as serum creatinine ≤ 1.5x upper limit of normal (ULN) for age.

Participants by arm

ArmCount
Nelarabine Dose Level 1
The study will begin at Dose Level 1 at 480 mg/m2 Nelarabine (75% of single agent MTD) and 330 mg/m2 Cyclophosphamide. The first 3 patients will be enrolled into Dose Level 1. If 0/3 experiences dose limiting toxicity (DLT) at a given dose level, then the dose is escalated to the next higher level and 3 more patients are enrolled. If 1/3 experiences DLT at current dose, the up to 3 more patients are accrued at the same dose level. If 2 or more DLTs are observed in a 3-patient or 6-patient cohort at a given dose level, then the MTD has been exceeded, dose escalation will be stopped, and up to 3 additional patients will be enrolled at the next lower dose level (unless 6 patients have already been treated at that prior dose). If the MTD is exceeded at Dose Level 0, the study will be closed.
6
Nelarabine Dose Level 2
Patients in this arm will be administered Nelarabine at 650 mg/m2 (100% of single agent MTD) and 330 mg/m2 Cyclophosphamide. This is the second dose level of this dose escalation study. If 1 or fewer patients at Dose Level 1 experiences a DLT, patients will be accrued at Dose Level 2. If 0/3 experiences dose limiting toxicity (DLT) at a given dose level, then the dose is escalated to the next higher level and 3 more patients are enrolled. If 1/3 experiences DLT at current dose, the up to 3 more patients are accrued at the same dose level. If 2 or more DLTs are observed in a 3-patient or 6-patient cohort at a given dose level, then the MTD has been exceeded, dose escalation will be stopped, and up to 3 additional patients will be enrolled at the next lower dose level (unless 6 patients have already been treated at that prior dose). If the MTD is exceeded at Dose Level 0, the study will be closed.
7
Nelarabine Dose Level 3
Patients in this arm will be administered Nelarabine at 650 mg/m2 (100% of single agent MTD) and 400 mg/m2 Cyclophosphamide This is the third and final dose level of this dose escalation study. If 1 or fewer patients at Dose Level 2 experiences a DLT, patients will be accrued at Dose Level 3. If 0/3 experiences dose limiting toxicity (DLT) at a given dose level, then the dose is escalated to the next higher level and 3 more patients are enrolled. If 1/3 experiences DLT at current dose, the up to 3 more patients are accrued at the same dose level. If 2 or more DLTs are observed in a 3-patient or 6-patient cohort at a given dose level, then the MTD has been exceeded, dose escalation will be stopped, and up to 3 additional patients will be enrolled at the next lower dose level (unless 6 patients have already been treated at that prior dose). If the MTD is exceeded at Dose Level 0, the study will be closed.
10
Nelarabine Dose Level 0
Patients in this arm will be administered Nelarabine 325 mg/m2 (50% of single agent MTD) and 330 mg/2 Cyclophosphamide. Patients will only enter this arm if the MTD at Dose Level 1 has been exceeded. If the MTD is exceeded at Dose Level 0, the study will be closed.
