NCT01158885

Brief Summary

This study will test the ability of clofarabine + cytarabine to eliminate minimal residual disease (MRD) in acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL) patients whose bone marrows exhibit complete remission by morphology. The toxicity profile of this regimen will be evaluated in addition to toxicity experienced by patients who proceed to stem cell transplant. Overall length of remission will also be collected.

Outcome Measures

Primary Outcomes (1)

  • Minimal Residual Disease (MRD)

    To be assessed in acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL) patients whose bone marrows exhibit complete remission by morphology. Patient's bone marrow will be evaluated for the amount of minimal residual disease (MRD) present after treatment on courses 1 and 2.

    Sample collected between Days 22-36 of courses 1 and 2

Secondary Outcomes (2)

  • Number of Patients With Dose-Limiting Toxicity (DLT)

    Beginning with the first dose of investigational product until day 56 of treatment course, an average of 1 year

  • Occurrence of Toxicity During Hematopoietic Cell Transplant (HCT) for Patients Who Achieve Remission and Proceed to Transplant

    Every 3 months for life following completion of protocol therapy.

Study Arms (1)

Single Arm

EXPERIMENTAL

A maximum of two courses of the following regimen will be administered. * Clofarabine: 20 mg/m2/day intravenously (IV) over 2 hours (given at hours 0 to 2) on days 1 through 5. * Cytarabine intravenous: 1 gram/m2/day intravenously (IV) over 2 hours to be given 4 hours after the initiation of clofarabine on days 1 through 5. * Methotrexate: to be given intrathecally (IT) to all acute lymphoblastic leukemia (ALL) patients on day 1 at the dose defined by age. * Intrathecal (IT) cytarabine: is optional for acute myelogenous leukemia (AML) patients.

Single Arm

Methotrexate to be given intrathecally (IT) to all acute lymphoblastic leukemia (ALL) patients on day 1 at the dose defined by age below: * 8 mg for patients age 1-1.99 * 10 mg for patients age 2-2.99 * 12 mg for patients 3-8.99 years of age * 15 mg for patients \>9 years of age

Single Arm

Intrathecal (IT) cytarabine is optional for acute myelogenous leukemia (AML) patients. If intrathecal cytarabine is to be given, it must be given at least 72 hours but not more than 7 days prior to the initiation of intravenous cytarabine. Dose should be given according to age as defined below: * 30 mg for patients age 1-1.99 * 50 mg for patients age 2-2.99 * 70 mg for patients \>3 years of age
