  Purpose
The purpose of this study is to test the safety of adding donor dendritic cells to donor lymphocyte infusions, and to determine the type and severity of any side effects associated with this addition. Previously patients with hematologic malignancies who relapsed after transplant have been given infusions of donor white blood cells (donor lymphocyte infusion, DLI) as a way to boost their immune function and fight disease. Although DLI has led to cancer regression in some patients, the overall response rate using DLI alone is low, and unfortunately, rarely lasting. Researchers have discovered a new subset of blood cells, called dendritic cells (DC), which are crucial partners to lymphocytes in generating an immune response. We believe that the infusion of DC together with DLI may improve the ability of the donor lymphocytes to recognize and kill cancer cells.

Primary Outcome Measures:
  • To determine the maximum tolerated dose of allogeneic DC in combination with DLI in patents with a relapsed hematologic malignancy following allogeneic hematopoietic stem cell transplantation. [ Time Frame: 4 years ]

Secondary Outcome Measures:
  • To assess clinical response after infusions of donor derived DC and donor lymphocytes
  • To assess the immunologic impact of infusions of donor derived DC and donor lymphocytes.

Enrollment: 25
Study Start Date: July 2003
Study Completion Date: July 2009
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Intervention Details:
    Biological: Infusion of donor dendritic cells
    Given in the outpatient setting
    Biological: Infusion of donor lymphocytes
    Given in outpatient setting
Detailed Description:
  • Since we are looking for the highest dose of donor dendritic cells that can be administered safely with DLI patients after allogeneic stem cell transplant, not everyone who participates in this study will be receiving the same number of dendritic cells.
  • The study procedure can be divided into 3 phases: 1) Pre-infusion evaluation, 2) Cell collections and infusions, 3) Follow-up after infusions.
  • Pre-infusion evaluation: Routine blood tests will be performed on both the participant and donor. The participant will undergo a bone marrow aspirate and biopsy if this has not been recently performed. During this time, additional standard blood tests and/or radiology tests may be done to fully determine the extent of the cancer.
  • Cell Collections: About 2-3 weeks before the infusion date, the donor will undergo one or two white blood cell collection procedures called leukopheresis. The cells collected from the first leukopheresis will be sent to the laboratory where a portion will be used to cultivate dendritic cells, and the remaining lymphocytes will be set aside for the DLI. If the number of cells collected at the first leukopheresis is insufficient, the donor will undergo a second leukopheresis procedure 7-10 days later.
  • Infusions: We plan to administer the dendritic cells and donor lymphocytes separately in the outpatient clinic. The dendritic cells will be given first, followed by the DLI one to two days later.
  • Follow-up after infusions: After completion of both the donor DC and DLI, participants will be followed closely for the development of side effects and response. They will be evaluated at least once a week, and routine blood tests and physical examination to assess for graft vs. host disease (GvHD) or other side effects will be performed. Additional blood tests will be done after 3, 6, and 10 weeks. At 10 weeks after the lymphocyte infusion, bone marrow aspirate and biopsy will be performed to assess the disease as well as the percentage of bone marrow cells that are derived from the donor. Additional restaging studies will also be performed at 10 weeks.
