Clofarabine in Treating Patients With T-Cell or Natural Killer-Cell Non-Hodgkin's Lymphoma That Has Relapsed or Not Responded to Previous Treatment
RATIONALE: Drugs used in chemotherapy, such as clofarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
PURPOSE: This phase I/II trial is studying the side effects and best dose of clofarabine and to see how well it works in treating patients with T-cell or natural killer-cell lymphoma that has relapsed or not responded to previous treatment.

|Official Title:||A Phase I/II Study of Clofarabine in Patients With Relapsed T-Cell and NK-Cell Lymphomas|
- Maximum tolerated dose (Phase I) [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- Response rate as defined by complete remission, complete remission unconfirmed, partial remission, positron emission tomography (PET)-negative partial remission, stable disease, and progressive disease (Phase II) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- Toxicity as defined by NCI Common Terminology Criteria for Adverse Events v 3.0 [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
|Study Start Date:||June 2006|
|Estimated Study Completion Date:||July 2014|
|Estimated Primary Completion Date:||July 2014 (Final data collection date for primary outcome measure)|
Patients will receive intravenous clofarabine once daily for three consecutive days. Doses of clofarabine will start at 4 mg/m2/day and will be escalated to higher dose levels.
- Determine the maximum tolerated dose of clofarabine in patients with relapsed or refractory T-cell or natural killer-cell lymphoma.
- Determine the toxicity of this drug in these patients.
- Determine, preliminarily, the efficacy of this drug, in terms of response rate, in these patients.
OUTLINE: This is a phase I, non-randomized, dose-escalation study followed by an open-label, phase II study.
- Phase I: Patients receive clofarabine IV over 1 hour once daily on days 1-3. Treatment repeats every 21 days for up to 2 courses in the absence of disease progression or unacceptable toxicity. Patients achieving stable disease or partial response (PR) or complete response (CR) may receive 2 additional courses of treatment. Patients with PR or CR after completing 4 courses of therapy may receive 2 additional courses.
Cohorts of 1-6 patients receive escalating doses of clofarabine 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.
- Phase II: Patients receive clofarabine as in phase I at the MTD determined in phase I.
After completion of study treatment, patients are followed every 3 months for 2 years.
