About

The purpose of this study is to determine the safety and effectiveness of a treatment regimen using Zevalin® plus Rituxan® for patients who have low grade Non-Hodgkin's Lymphoma (NHL) or relapsed Non-Hodgkin's lymphoma and have been previously treated. This study will use an experimental scheduling regimen. No chemotherapy will be used in this study.

Full description

The objective of this study is to determine overall response rate, event-free survival, time-to-progression, time-to-next-therapy, and freedom-from-relapse in patients with low-grade lymphoma in first or second relapse treated with Zevalin followed by 2 years of Rituxan maintenance therapy in a multicenter, community-based setting, as well as evaluate relative response rates in populations with and without prior rituximab therapy, in first versus second relapse, and with and without bulky (> 5 cm in greatest diameter) disease.

To meet the initial trial enrollment goal of 300 patients over two years, 42 total sites were activated. The study has subsequently closed to accrual. Currently 8 sites remain active to follow the 12 subjects enrolled in the past year.
