Irinotecan and Cytarabine in Treating Patients With Refractory or Recurrent Acute Myeloid Leukemia or Chronic Myelogenous Leukemia
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 I trial to study the effectiveness of combining irinotecan with cytarabine in treating patients who have refractory or recurrent acute myeloid leukemia or chronic myelogenous leukemia.

|Study Start Date:||November 1999|

- Determine the activity of irinotecan and cytarabine in patients with refractory or recurrent acute myeloid leukemia or chronic myelogenous leukemia in myeloid blast transformation.
- Determine the pharmacokinetics of this regimen in these patients.
- Determine the maximum tolerated dose of irinotecan in this regimen in these patients.
- Correlate the clinical activity of this drug with cellular endpoints associated with DNA synthesis inhibition, DNA repair, induction of apoptosis, and drug resistance in these patients.
OUTLINE: This is a dose-escalation study of irinotecan.
Patients receive irinotecan IV over 90 minutes and cytarabine IV over 60 minutes on days 1-6. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of irinotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity. An additional 9 patients with refractory/relapsed acute myeloid leukemia and 9 patients with chronic myelogenous leukemia in myeloid blast transformation are treated at the MTD.
Patients are followed for survival.
PROJECTED ACCRUAL: A total of 3-36 patients will be accrued for this study within 2.5 years.
