Title: FL-2000 Study for Newly Diagnosed Follicular Lymphoma Patients With a High Tumor Burden
Brief Summary: The purpose of this study is to assess in a prospective multicentric study (Phase III) the introduction of a monoclonal antibody directed against B-cells associated with a standard therapy including chemotherapy and alpha-interferon in first line treatment of patients with a large tumor burden follicular lymphoma.
