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.

Condition Intervention Phase
Biological: rituximab
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

Primary Outcome Measures:
  • Response (delay in disease progression or timing of disease progression) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    Define objective response (delay in disease progression or timing of disease progression), time to treatment failure, and toxicity for single agent Rituxan therapy in Waldenstrom's macroglobulinemia patients

Secondary Outcome Measures:
  • Expression of CD20 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    To correlate expression and changes in expression of CD20 on waldenstrom's macroglobulinemia patient plasma cells and B-cells with clinical responses.

Enrollment: 8
Study Start Date: December 1999
Study Completion Date: July 2005
Primary Completion Date: January 2002 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Rituxan
375 mg/m2 given as an intravenous (IV) infusion once weekly for four doses (days 1, 8, 15, and 22). For purposes of this study 4 weekly courses will constitute one cycle of therapy.
Biological: rituximab
375 mg/m2 given as an intravenous (IV) infusion once weekly for four doses (days 1, 8, 15, and 22). For purposes of this study 4 weekly courses will constitute one cycle of therapy.
Other Name: Rituxan

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.
