Rituximab in Treating Patients With Refractory or Relapsed Primary CNS Lymphoma
A Phase II Study Of Anti-CD20 Monoclonal Antibody (Rituximab) Therapy For Patients With Refractory Or Relapsed Primary CNS Lymphoma (PCNSL)
RATIONALE: Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells.
PURPOSE: Phase II trial to study the effectiveness of rituximab in treating patients who have refractory or relapsed primary CNS lymphoma.
연구 개요
상세 설명
OBJECTIVES:
Primary
- Determine the radiographic response proportion in patients with refractory or recurrent primary CNS lymphoma treated with rituximab.
Secondary
- Determine the progression-free and overall survival of patients treated with this drug.
- Determine the toxicity profile of this drug in these patients.
OUTLINE: This is a multicenter study.
Patients receive rituximab IV on days 1, 8, 15, and 22. Treatment repeats every 28 days for 2 courses in the absence of disease progression or unacceptable toxicity. Patients may receive additional courses of rituximab off study at the discretion of the treating physician.
Patients are followed every 2 months.
PROJECTED ACCRUAL: A total of 15-25 patients will be accrued for this study within 5-9 months.
