About

RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others, such as yttrium Y 90 ibritumomab tiuxetan, find cancer cells and help kill them or carry cancer-killing substances to them without harming normal cells. Giving rituximab together with yttrium Y 90 ibritumomab tiuxetan may kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving rituximab together with yttrium Y 90 ibritumomab tiuxetan works in treating patients with indolent non-Hodgkin's lymphoma.

Full 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.

Enrollment: 12 patients

Sex: All

Ages: 18 to 120 years old

Volunteers: No Healthy Volunteers
