Rituximab in Treating Patients With Waldenstrom's Macroglobulinemia

Phase 2
Completed
Conditions
Lymphoma
Interventions
Biological: rituximab
Registration Number
NCT00004889
Lead Sponsor
Jonsson Comprehensive Cancer Center
Brief Summary

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.

PURPOSE: Phase II trial to study the effectiveness of rituximab in treating patients who have Waldenstrom's macroglobulinemia.

Detailed Description

OBJECTIVES: I. Determine the objective response, time to treatment failure, and toxicity in patients with Waldenstrom's macroglobulinemia treated with rituximab. II. Correlate expression and changes in expression of CD20 on patient plasma cells and B-cells with clinical responses.

OUTLINE: This is a multicenter study. Patients receive rituximab IV weekly for 4 weeks. Treatment may be repeated 2 months later in patients with stable disease, partial response, or complete response. Patients are followed every 6 months for 2 years.

PROJECTED ACCRUAL: A total of 12-25 patients will be accrued for this study.
