Alternate Title

Arsenic Trioxide in Treating Patients With Relapsed or Refractory Lymphoma or Leukemia

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II Treatment Completed 18 and over NCI MTS-99-884-ME NCI-T99-0063, NCT00005786, T99-0063

Objectives

1. Determine the safety and toxicity profile of arsenic trioxide in patients with relapsed or refractory indolent lymphoma or leukemia.
2. Determine the incidence of complete and partial responses in this patient population when treated with this drug.
3. Evaluate basic science correlates of this drug's activity and mechanism of action in these patients.

Entry Criteria

Disease Characteristics:

• Diagnosis of relapsed or refractory indolent lymphoma or leukemia
  • B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma

  • Grade I or II follicular lymphoma
  • Nodal marginal zone B-cell lymphoma
  • Extranodal marginal zone B-cell lymphoma (MALT)
  • Splenic marginal zone lymphoma with or without villous lymphocytes



• Relapsed disease is defined as development of any of the following after a prior response of at least 6 months duration:
  • Lymphadenopathy
  • Splenomegaly
  • Malignant lymphocytosis greater than 5,000/mm³

Expected Enrollment

A total of 16-25 patients will be accrued for this study within 1-1.5 years.

Outline

This is a nonrandomized, open-label study.

Patients receive arsenic trioxide IV over 1-4 hours on days 1-5. Treatment repeats every 21 days for a maximum of 6 courses in the absence of unacceptable toxicity or disease progression. Patients with responding or stable disease may receive 6 additional courses.

Patients are followed every 3 months for up to 2 years.
