Phase I/II trial to study the effectiveness of combining yttrium Y 90 ibritumomab tiuxetan with rituximab in treating patients who have localized or recurrent lymphoproliferative disorder after an organ transplant. Monoclonal antibodies such as yttrium Y 90 ibritumomab tiuxetan and rituximab can locate cancer cells and either kill them or deliver radioactive cancer-killing substances to them without harming normal cells

Study summary:

OBJECTIVES: I. Determine the safety and tolerability of yttrium Y 90 ibritumomab tiuxetan (IDEC-Y2B8) in patients with post-transplant lymphoproliferative disorder. II. Determine the safety and toxicity profile of IDEC-Y2B8 and rituximab in these patients. III. Correlate the Epstein-Barr virus viral load with response and relapse in patients treated with this regimen. OUTLINE: This is a multicenter, dose-escalation study of yttrium Y 90 ibritumomab tiuxetan (IDEC-Y2B8). Phase I: Patients receive rituximab IV and indium In 111 ibritumomab tiuxetan IV over 10 minutes on day 1. Patients undergo 2 (or 3 if needed) imaging scans between days 1-6. In the absence of altered biodistribution, patients receive rituximab IV followed within 4 hours by IDEC-Y2B8 IV over 10 minutes on day 8.Cohorts of 6 patients receive escalating doses of IDEC-Y2B8 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 6 patients experience dose-limiting toxicity. Phase II: Patients receive treatment as in phase I at the MTD of IDEC-Y2B8. Patients are followed monthly for 3 months, every 3 months for 2 years, and then every 6 months for 2 years.
