Y 90 Ibritumomab Tiuxetan &Rituximab Relapsed or Refractory Diffuse Large B-Cell Non-Hodgkin's Lymphoma
Description
OBJECTIVES:
Determine the best overall response in patients with relapsed or refractory diffuse large B-cell non-Hodgkin's lymphoma treated with yttrium Y 90 ibritumomab tiuxetan and rituximab.
Determine the event-free survival of patients treated with this regimen.
Determine the toxicity of this regimen in these patients.
OUTLINE: This is an open-label, multicenter study.
Radioimmunotherapy: Patients receive indium In 111 ibritumomab tiuxetan IV over 10 minutes on day 1 (for imaging only); yttrium Y 90 ibritumomab tiuxetan IV over 10 minutes on day 8; and rituximab IV over 3-4 hours on days 1, 8, 15, 22, 29, and 36.
CNS ( central nervous system)prophylaxis: Patients receive CNS prophylaxis comprising intrathecal (IT) methotrexate or IT cytarabine on days 15, 22, 29, and 36 OR IT cytarabine (liposomal) on days 15 and 29.
Maintenance rituximab: Patients are assessed for response at week 14. Beginning at month 6, patients with stable or responding disease receive maintenance therapy comprising rituximab IV over 3-4 hours once weekly for 4 weeks. Maintenance therapy repeats every 6 months for 2 years (total of 4 courses) in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months for 2 years and then every 6 months for 2 years.
PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study within 2 years.
