Brief Summary:
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/II trial to study the effectiveness of combination chemotherapy in treating patients who have previously untreated acute myeloid leukemia.
Detailed Description:
OBJECTIVES:
* Determine the maximum tolerated dose (MTD) of topotecan when combined with daunorubicin, cytarabine, and etoposide in patients with de novo acute myeloid leukemia.
* Determine the efficacy of this regimen at the MTD of topotecan by measuring the complete response rate in this patient population.
* Determine the days of hospitalization and number of infections associated with this regimen in these patients.
* Correlate serum levels of topotecan and etoposide with the expression of topoisomerase I and II in tumor cells and in peripheral blood mononuclear cells (PBMN), as well as with toxicity and response rate in these patients.
* Correlate tumor cell and PBMN expression and activity of topoisomerase I and II with hematological toxicity and clinical response in these patients.
* Correlate levels of activation of STAT signaling proteins with expression of bcl-2 family proteins and response to chemotherapy in these patients.
OUTLINE: This is a dose-escalation study of topotecan (phase I) followed by a response rate-determination (phase II) study.
Patients receive induction chemotherapy with daunorubicin IV over 10-15 minutes on days 1-3, cytarabine IV continuously on days 1-5, topotecan IV continuously on days 6-8, and etoposide IV over 60 minutes on days 9 and 10. Within 4 weeks of hematologic recovery, patients achieving remission after induction receive consolidation chemotherapy with cytarabine IV over 1 hour every 12 hours on days 1, 3, and 5. Subsequent courses of consolidation chemotherapy begin within 2 weeks of documentation of hematologic recovery from the prior consolidation course. Consolidation chemotherapy continues for 4 courses in the absence of unacceptable toxicity or disease progression.
Cohorts of 3-6 patients receive escalating doses of topotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, additional patients are accrued to receive induction chemotherapy at the recommended phase II dose.
Patients are followed at 1 month, every 2 months for 1 year, every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 3-36 patients (phase I) and then an additional 24-27 patients (phase II) will be accrued for this study within 4 years.
