Rituximab and Yttrium Y 90 Ibritumomab Tiuxetan in Treating Patients With Non-Hodgkin's Lymphoma
Description
OBJECTIVES:
Primary
Determine 12-week overall and complete response rate in patients with indolent non-Hodgkin's lymphoma treated with rituximab and yttrium Y 90 ibritumomab tiuxetan as first-line treatment.
Secondary
Determine 1-year event-free survival of patients treated with this regimen.
Determine time to progression and time to next antilymphoma therapy in patients treated with this regimen.
Determine the molecular response rate in patients treated with this regimen.
Determine the hematological and non-hematological toxicity of this regimen in these patients.
Assess the quality of life of patients treated with this regimen.
OUTLINE: This is an open-label, multicenter study.
Patients receive rituximab IV followed, no more than 4 hours later, by indium In 111 ibritumomab tiuxetan (for imaging) IV over 10 minutes on day 1. If biodistribution is acceptable, patients receive rituximab IV followed, no more than 4 hours later, by a single dose of yttrium Y 90 ibritumomab tiuxetan IV over 10 minutes on day 7, 8, or 9 in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline, weeks 6, 10, and 14, every 3 months for 2 years, and then every 6 months for 2 years.
After completion of study treatment, patients are followed weekly for 3 months, every 3 months for 2 years, and then every 6 months for 2 years.
PROJECTED ACCRUAL: A total of 18-28 patients will be accrued for this study within 2 years.
