Study of Rituximab Plus High-Dose Chemotherapy Non-Hodgkin's Lymphoma

University of Michigan Rogel Cancer Center35 enrolled

Overview

This study is being conducted to determine the safety, side effects, and response to a combination of an established high-dose chemotherapy regimen, plus the addition of Rituximab (which is a form of immunotherapy).

Combination chemotherapy is the standard treatment as initial therapy for advanced stage aggressive Non-Hodgkin's lymphoma (NHL). Standard chemotherapy cures less than 40% of patients. When patients relapse, they may be eligible to receive high-dose chemotherapy with autologous stem cell support. Multiple studies have shown the value of high-dose chemotherapy, with increased disease-free survival and overall survival, when compared with second-line conventional chemotherapy. Unfortunately high-dose chemotherapy is curative in less than half the patients who receive it, and other treatment strategies are needed to improve the cure rate. Another treatment option called immunotherapy is being tested in lymphoma patients. Immunotherapy involves attempts to use the immune system or products of the immune system to fight lymphoma. For example, NHL cells have a protein called CD20 on their surface. Rituximab is an antibody directed against the CD20 protein, which may result in the death of the lymphoma cell. Patients in this study will receive Rituximab to see if it is a safe treatment option for NHL patients.
