  Purpose

RATIONALE: Biological therapies, such as denileukin diftitox, may be able to carry cancer-killing substances directly to non-Hodgkin's lymphoma cells.

PURPOSE: This phase II trial is studying how well denileukin diftitox works in treating patients with relapsed or refractory B-cell non-Hodgkin's lymphoma.


Condition Intervention Phase
Lymphoma Biological: denileukin diftitox Phase 2

Study Type: Interventional
Study Design: Masking: None (Open Label)

Primary Outcome Measures:
  • Objective clinical response (complete or partial response)

Secondary Outcome Measures:
  • Time to progression
  • Overall survival at 1 year
  • Safety

Estimated Enrollment: 50
Study Start Date: December 2004
Study Completion Date: November 2008
Primary Completion Date: February 2006 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

Primary

  • Determine the efficacy of denileukin diftitox, in terms of objective response and time to progression, in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma.

Secondary

  • Determine the safety of this drug in these patients.
  • Determine the 1-year overall survival of patients treated with this drug.

OUTLINE: This is an open-label, multicenter study.

Patients receive denileukin diftitox IV over 20-80 minutes on days 1-3, 8, 15, 22, 29, 36, 43, 50, 57, 64, 71, 78, 85, 92, and 99 (weeks 1-16) in the absence of disease progression or unacceptable toxicity. Patients achieving a partial response at week 16 may continue treatment once monthly for up to 8 additional doses or until a complete response (CR) is achieved. Patients achieving a CR (at any time) receive 2 additional monthly doses of denileukin diftitox beyond CR.

After completion of study treatment, patients are followed at 4 weeks and then every 3 months thereafter.

PROJECTED ACCRUAL: A total of 25-50 patients will be accrued for this study within 1 year.

Criteria

DISEASE CHARACTERISTICS:

  • Histologically confirmed B-cell non-Hodgkin's lymphoma (NHL) of 1 of the following subtypes:

    • Diffuse large B-cell lymphoma
    • Follicular lymphoma (grades 1-3)
    • Small lymphocytic lymphoma
    • Transformed B-cell lymphoma
  • Relapsed or refractory disease

    • Disease failed to respond to or progressed after ≥ 2 prior treatment regimens (e.g., high-dose therapy [HDT] with stem cell transplantation [SCT]*) NOTE: *Patients who have received HDT with SCT are considered to have diminished bone marrow reserve

    • WBC ≥ 2,000/mm^3 but < 4,000/mm^3 (growth factor independent)
    • Platelet count ≥ 40,000/mm^3 (25,000/mm^3 if thrombocytopenia is secondary to marrow involvement by lymphoma) but < 150,000/mm^3 (platelet transfusion independent)
