About

RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some find cancer cells and kill them or carry cancer-killing substances to them. Others interfere with the ability of cancer cells to grow and spread. Vaccines made from a person's cancer cells may help the body build an effective immune response to kill cancer cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving rituximab together with vaccine therapy and GM-CSF may kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving rituximab together with vaccine therapy and GM-CSF works in treating patients with indolent B-cell non-Hodgkin's lymphoma.

Full description

OBJECTIVES:

• Determine the efficacy of immunotherapy comprising rituximab, autologous immunoglobulin idiotype-KLH conjugate vaccine (FavId™), and sargramostim (GM-CSF), in terms of response rate (partial and complete) and event-free survival, in patients with indolent B-cell non-Hodgkin's lymphoma.
• Determine the safety of this regimen in these patients.
• Evaluate development of an immune response in patients treated with this regimen.

OUTLINE: This is an open-label, multicenter study.

• Induction therapy: Patients receive rituximab IV over 2-4 hours once weekly for 4 weeks. Patients are evaluated for response at month 3. Patients with responding or stable disease proceed to maintenance therapy. Patients with progressive disease are removed from study.
• Maintenance therapy: Patients receive rituximab as in induction therapy in months 7, 13, and 19. Patients also receive autologous immunoglobulin idiotype-KLH conjugate vaccine (FavId™) subcutaneously (SC) once on day 1 and sargramostim (GM-CSF) SC once daily on days 1-4 in months 4-6, 8-11, 14, 16, 18, 20, 22, and 24. Patients with continued response after completing 2 years of therapy may continue to receive FavId™ and GM-CSF once every 3 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 56 patients will be accrued for this study.
