Chronic Lymphoid Leukemia (CLL)

Bexxar Consolidation CLL or SLL (PSOC 2301)
A Study of 131-Tositumomab (Bexxar) Consolidation In Patients With B-Cell Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma In First Remission
Status Conditions Phase Study ID
Closed Chronic Lymphocytic Leukemia
Small Lymphocytic Lymphoma
Phase II PSOC 2301
NCT00476047
Summary

This study is evaluating the use of radioimmunotherapy (Bexxar®) in patients who have achieved a first remission following chemotherapy (ex. Fludarabine and Rituximab, Fludarabine,Cyclophosphamide,Rituximab, etc...) to try and eliminate any remaining disease and to lower the chance of the CLL from returning. Radioimmunotherapy uses an antibody that is designed to target specific cancer cells such as the CLL cells, and deliver a small targeted dose of radiation to them. In this study we will gather more information about the safety and effectiveness of using a radiolabeled antibody therapy, 131 I-tositumomab, also called Bexxar® after standard therapy.
