Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Deoxycytidine may protect patients from the side effects of high-dose cytarabine.

PURPOSE: Phase I trial to study the effectiveness of high-dose cytarabine given with deoxycytidine in treating patients who have refractory acute myelogenous leukemia or other lymphoma or leukemia.


Description:

OBJECTIVES: I. Estimate the lowest dose of deoxycytidine (dC) that can be given as a host protective agent in conjunction with high dose cytarabine (HD ARA-C) in patients with refractory acute myelogenous leukemia or other hematologic malignancies. II. Determine the maximum tolerated dose and dose-limiting toxic effects of HD ARA-C/dC in these patients. III. Characterize the pharmacokinetics of continuously administered HD ARA-C/dC in these patients. IV. Characterize, when possible, the pharmacodynamics of HD ARA-C, dC, and their metabolites in blasts obtained from leukemic patients participating in this trial. V. Recommend the lowest possible dose of dC that can be given in combination with HD ARA-C in future phase II trials.

OUTLINE: This is a dose escalation study. Patients receive deoxycytidine IV over 120 hours. Beginning 12 hours after initiation of deoxycytidine, patients receive high dose cytarabine IV over 96 hours. Patients achieving complete response receive no further therapy. Patients achieving partial response or initial complete response and subsequent relapse receive an additional course of therapy. Cohorts of 3-6 patients receive escalating doses of deoxycytidine and high dose cytarabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicities.

PROJECTED ACCRUAL: Approximately 24-30 patients will be accrued for this study.
