RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells.

PURPOSE: Phase II trial to study the effectiveness of idarubicin and cladribine in treating children who have recurrent acute myeloid leukemia.

Condition	Treatment or Intervention	Phase
Acute Myeloid Leukemia	Drug: cladribine  Drug: filgrastim  Drug: idarubicin  Procedure: biological response modifier therapy  Procedure: chemotherapy  Procedure: colony-stimulating factor therapy  Procedure: cytokine therapy	Phase II

Further Study Details: 

OBJECTIVES:

• Determine the complete response rate in children with primary refractory or recurrent acute myeloid leukemia (AML) or secondary AML treated with idarubicin and cladribine. (Refractory AML stratum closed as of 4/3/01) (Secondary AML stratum closed as of 04/02/02)
• Compare the remission reinduction rates in children who relapse at 1 year or earlier vs more than 1 year from time of initial remission.
• Determine the toxic effects of this regimen in this patient population.

OUTLINE: Patients are stratified according to disease characteristics (primary or secondary acute myeloid leukemia (AML) with first untreated relapse vs primary refractory AML). (Refractory AML stratum closed as of 4/3/01) (Secondary AML stratum closed as of 04/02/02)

Patients receive idarubicin IV over 15 minutes on days 1-3, cladribine IV over 2 hours on days 1-5, and filgrastim (G-CSF) subcutaneously beginning on day 6 and continuing until blood counts have recovered for 2 days. Treatment repeats every 3 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve complete response after completion of course 1 may proceed to other chemotherapy or bone marrow transplantation at the discretion of the protocol investigator. Patients with extramedullary disease may receive intrathecal chemotherapy or radiotherapy to symptomatic sites.

Patients are followed every 3 months for 1 year, every 6 months for 4 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 51-102 patients will be accrued for this study within 3 years.

Ages Eligible for Study:  up to  21 Years,  Genders Eligible for Study:  Both
