Yttrium Y 90 Ibritumomab Tiuxetan in Treating Patients With Waldenstrom's Macroglobulinemia
RATIONALE: Monoclonal antibodies such as yttrium Y 90 ibritumomab tiuxetan and rituximab can locate cancer cells and either kill them or deliver radioactive cancer-killing substances to them without harming normal cells.
PURPOSE: Phase I trial to study the effectiveness of yttrium Y 90 ibritumomab tiuxetan in treating patients who have Waldenstrom's macroglobulinemia.
Radiation: yttrium Y 90 ibritumomab tiuxetan
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase I Study of Zevalin (90Y-Ibritumomab Tiuxetan) in Waldenstrom's Macroglobulinemia (Lymphoplasmacytic Lymphoma)|
|Study Start Date:||April 2003|
|Primary Completion Date:||June 2004 (Final data collection date for primary outcome measure)|
- Determine the maximum tolerated dose of yttrium Y 90 ibritumomab tiuxetan in patients with Waldenstrom's macroglobulinemia.
- Determine, preliminarily, the response of patients treated with this drug.
OUTLINE: This is a multicenter, dose-escalation study of yttrium Y 90 ibritumomab tiuxetan (IDEC-Y2B8).
Patients receive rituximab IV and indium In 111 ibritumomab tiuxetan (IDEC-In2B8) IV over 10 minutes on day 1. Patients then undergo gamma camera scans within 2-24 hours. Approximately 7-14 days after IDEC-In2B8, patients receive rituximab IV and IDEC-Y2B8 IV over 10 minutes. Treatment with IDEC-Y2B8 may repeat every 12 weeks in the absence of unacceptable toxicity or the achievement of a maximum cumulative dose.
Cohorts of 3-6 patients receive escalating doses of IDEC-Y2B8 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.
Patients are followed every 3 months for 4 years.
PROJECTED ACCRUAL: A total of 3-24 patients will be accrued for this study.
