Trial Information

A Phase I/II Study of Clofarabine in Patients With Relapsed T-Cell and NK-Cell Lymphomas


OBJECTIVES:

Primary

- 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.
