RATIONALE: Drugs used in chemotherapy, such as fludarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. 3-AP may help fludarabine kill more cancer cells by making them more sensitive to the drug.
PURPOSE: This phase I trial is studying the side effects and best dose of fludarabine when given together with 3-AP in treating patients with relapsed or refractory acute leukemia, chronic leukemia, or high-risk myelodysplastic syndrome.
|Condition or disease||Intervention/treatment||Phase|
|Leukemia Myelodysplastic Syndromes Myelodysplastic/Myeloproliferative Diseases||Drug: fludarabine phosphate Drug: triapine||Phase 1|
- Determine the feasibility and tolerability of 3-AP (Triapine^® ) followed by fludarabine in patients with relapsed or refractory acute or chronic leukemia or high-risk myelodysplastic syndromes.
- Determine the toxic effects of this regimen in these patients.
- Determine the maximum tolerated dose of this regimen in these patients.
OUTLINE: This is a multicenter, dose-escalation study of fludarabine. Patients are stratified according to disease (acute leukemias and myelodysplastic syndromes [MDS] vs chronic lymphocytic leukemia and prolymphocytic leukemia). Patients are assigned to 1 of 2 treatment groups.
- Group 1 (chronic lymphocytic leukemia or prolymphocytic leukemia): Patients receive 3-AP (Triapine^®) IV over 4 hours and fludarabine IV over 30 minutes on days 1-5.
Cohorts of 3-6 patients receive escalating doses of fludarabine 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 toxicity. Once the MTD is determined, 10 additional patients are treated at that dose level.
- Group 2 (acute leukemias or MDS): Patients receive 3-AP IV continuously over 24 hours on day 1. Beginning within 4 hours after completion of 3-AP, patients receive fludarabine IV over 30 minutes on days 2-6.
In both groups, treatment repeats every 3 weeks in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 3-34 patients will be accrued for this study.
