Combination Chemotherapy With or Without Rituximab in Treating Patients With Newly Diagnosed Non-Hodgkin's Lymphoma

Lymphoma Clinical Trial

Official title: A Phase III Randomized Trial of CHOP Chemotherapy Plus Rituxan (IDEC-C2B8) Versus CHOP Chemotherapy Alone for Newly Diagnosed, Previously Untreated, Aggressive Non-Hodgkin's Lymphoma

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. It is not yet known whether combination chemotherapy plus rituximab is more effective than combination chemotherapy alone for non-Hodgkin's lymphoma.

PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without rituximab in treating patients who have newly diagnosed non-Hodgkin's lymphoma that has not been treated previously.

Clinical Trial Description

OBJECTIVES: I. Determine whether the addition of rituximab to cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) increases the failure-free survival of patients with newly diagnosed, previously untreated, aggressive B-cell non-Hodgkin's lymphoma. II. Determine whether the addition of rituximab changes the toxicity profile attributed to CHOP chemotherapy in this patient population.

OUTLINE: This is a randomized, multicenter study. Patients are stratified by center, histology (diffuse small cleaved cell, diffuse mixed, and diffuse large cell vs immunoblastic large cell, mantle cell, and marginal zone), and risk group (low vs intermediate vs high). Patients enter one of two treatment arms: Arm I: Patients receive rituximab IV on day 1, followed by cyclophosphamide IV, doxorubicin IV, vincristine IV, and oral prednisone for 5 consecutive days beginning on day 3. Arm II: Patients receive cyclophosphamide IV, doxorubicin IV, vincristine IV, and oral prednisone daily for 5 consecutive days beginning on day 1. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients will be followed for 3 years.

PROJECTED ACCRUAL: A total of 270 patients (135 per treatment arm) will be accrued for this study within 3 years. ;
