Brief Summary:

RATIONALE: Cellular adoptive immunotherapy uses a person's white blood cells that are treated in the laboratory to stimulate the immune system in different ways and stop cancer cells from growing. Rituximab and fludarabine may also prevent the body from making an immune response against the laboratory-treated white blood cells that are put back into the body. Interleukin-2 may help the laboratory-treated white blood cells stay in the body longer. Giving cellular adoptive immunotherapy together with rituximab, fludarabine, and interleukin-2 may kill more cancer cells.

PURPOSE: This phase I trial is studying the side effects of cellular adoptive immunotherapy in treating patients with relapsed or refractory follicular non-Hodgkin's lymphoma.

Condition or disease Intervention/treatment Phase
Lymphoma Biological: aldesleukin Biological: rituximab Biological: therapeutic autologous lymphocytes Drug: fludarabine phosphate Phase 1

Detailed Description:



  • Determine the safety and feasibility of cellular adoptive immunotherapy using autologous cytotoxic T lymphocytes genetically modified to express a CD19-specific chimeric immunoreceptor gene and HyTK selection/suicide gene in patients with relapsed or refractory follicular non-Hodgkin's lymphoma.


  • Determine the in vivo persistence of adoptively transferred cytolytic T cells in patients treated with lymphodepleting therapy comprising rituximab and fludarabine.
  • Assess the development of host immune responses against the CD19-specific chimeric immunoreceptor gene and/or HyTK selection/suicide gene.
  • Determine the safety of low-dose interleukin-2 in supporting in vivo persistence of adoptively transferred cytotoxic T cells.
  • Determine the anti-tumor activity of this regimen in these patients.

OUTLINE: This is a nonrandomized, open-label, pilot study.

  • Leukapheresis: Patients undergo leukapheresis for collection of peripheral blood mononuclear cells (PBMCs). CD3-positive cytotoxic T lymphocytes (CTLs) are isolated and genetically modified to express a CD19-specific chimeric immunoreceptor and the HyTK fusion protein, and are then expanded in vitro.
  • Lymphodepleting therapy: Patients receive rituximab and fludarabine prior to T-cell infusions.
  • Cellular adoptive immunotherapy and interleukin-2 (IL-2): Patients receive a total of 5 infusions of genetically modified autologous T cells. Patients may receive low-dose IL-2 subcutaneously after infusions 3, 4, and 5.
  • Additional IL-2 therapy: After the completion of the last T-cell infusion, patients with evidence of adoptively transferred T cells may receive additional IL-2.

After completion of study treatment, patients are followed periodically for approximately 65 days and then annually for at least 15 years.

PROJECTED ACCRUAL: At least 5 patients will be accrued for this study within 3 years.

Ages Eligible for Study:   16 Years to 70 Years   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  • Histologically confirmed follicular non-Hodgkin's lymphoma (NHL)

    • High-risk disease, as defined by any of the following:

      • Relapsed within 6 months after the last treatment
      • Failed to achieve a complete response during the last treatment
      • Relapsed after prior autologous hematopoietic stem cell transplantation (HSCT)
  • No current transformation of lymphoma (e.g., elements of intermediate- or high-grade lymphoma by biopsy)
  • No active CNS disease by lumbar puncture or radiology scan NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
