NCT ID: NCT00138164

Last Updated: 2013-05-30

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 50 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2004-12-31
• Study Completion Date: 2008-11-30

Brief Summary

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.

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.

Eligibility Criteria

Inclusion Criteria

DISEASE CHARACTERISTICS:
