  Purpose

RATIONALE: Drugs used in chemotherapy, such as cytarabine and clofarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.

PURPOSE: This phase II trial is studying clofarabine when given together with cytarabine to see how well they work in treating patients with refractory or relapsed acute myeloid leukemia or acute lymphoblastic leukemia.

Primary Outcome Measures:
  • Measure Patient Response to High-dose Cytarabine Followed by Clofarabine in Adult Patients With Relapsed or Refractory AML [ Time Frame: 5 weeks ]
    Response to the therapy is measured by a defined improvement in Neutrophil and platlet counts, along with improved cellularity of bone marrow biopsy (>20% with maturation of all cell lines), <5% blasts, auer rods must not be detectable and extramedullary leukemia or soft tissue involvment must not be present.


Enrollment: 39
Study Start Date: February 2005
Study Completion Date: November 2008
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: high-dose cytarabine and clofarabine
high-dose cytarabine (2000 milligram/meter squared/day) administered intravenously over 3 hours followed by clofarabine administered intravenously over 2 hours daily for 5 consecutive days
Drug: clofarabine Drug: cytarabine

Detailed Description:

OBJECTIVES:

  • Determine the response rate in adult patients with relapsed or refractory acute myeloid leukemia or acute lymphoblastic leukemia treated with high-dose cytarabine followed by clofarabine.

OUTLINE: This is an open-label phase II study. Patients are stratified according to diagnosis (acute myeloid leukemia vs acute lymphoblastic leukemia Phase II: Patients receive high-dose cytarabine followed by clofarabine (at the dose determined in phase I) on days 1-3.

After completion of study treatment, patients are followed periodically for up to 5 years.

PROJECTED ACCRUAL: A total of 39 patients were accrued for this study.
