Spots Global Cancer Trial Database for A Phase I/II Study of Induction Chemotherapy With Daunorubicin, Cytarabine, Topotecan and Etoposide

Study Description

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.
