- Brief Summary
RATIONALE: Giving chemotherapy followed by treated T cells before a stem cell transplant stops the growth of cancer cells by stopping them from dividing or by killing them. After treatment, stem cells are collected from the patient's blood and stored. High-dose chemotherapy is given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.
PURPOSE: This phase I trial is studying the side effects and best way to give treated T cells followed by stem cell transplant in treating patients with multiple myeloma.
- Detailed Description
OBJECTIVES:
Primary
* To test the feasibility and safety of infusing anti-CD3 x anti-CD20 bispecific antibody-armed activated T cells (CD20Bi-AATC) before stem cell mobilization and collection for autologous peripheral blood stem cell transplantation (PBSCT) in patients with multiple myeloma.
Secondary
* To explore functional changes in immune cell populations as a consequence of immunotherapy to test the hypothesis that CD20Bi-AATC can induce anti-clonogenic myeloma precursor cell (CMPC) effect as measured by cytotoxicity; serum cytokine levels; and serum antibody titers to myeloma cells pre-immunotherapy, after immunotherapy, and after high-dose chemotherapy and autologous PBSCT.
* To explore whether the infusion of CD20Bi-AATC reduces the proportion of plasma cells with the CD20+ CMPC phenotype in patients' bone marrow as assessed by multi-color flow cytometry before and after immunotherapy.
* To assess the proportion of bone marrow colony-forming assays before induction or salvage chemotherapy, pre-immunotherapy, and post-immunotherapy to determine whether the infusion grossly affects the bone marrow progenitor populations.
* To explore whether infusions of CD20Bi-AATC induce a B-cell defect causing an immunoglobulin deficiency after autologous PBSCT.
* To measure immunoglobulin deficiency after autologous PBSCT (e.g., quantitative IgG, IgM, and IgA levels and number of circulating T- and B-cell subsets).
OUTLINE: After completion of induction or salvage chemotherapy, patients receive immunotherapy comprising anti-CD3 x anti-CD20-armed ATC IV weekly for 2 weeks. At least 1-3 weeks after the second infusion, patients receive high-dose chemotherapy and then undergo autologous peripheral blood stem cell transplantation. Patients then undergo leukapheresis for G-CSF-mobilized autologous T-cells.
Blood samples are collected periodically to evaluate antibody titers to recall antigens; serum IgG, IgM, and IgA levels; the proportion of circulating B-cells by phenotyping for CD19, CD20, CD22, CD23, CD4, CD8, and CD38; the ability of peripheral blood mononuclear cells to kill multiple myeloma cell lines or the patient's own cryopreserved myeloma cells via cytotoxicity assays and ELISPOT assays; and human anti-mouse antibody responses to murine IgG2a (OKT3). Bone marrow biopsies are also collected to analyze the phenotype of cells (CD20+, CD138-, CD27+, CD22, etc.) via flow cytometry and the proportion of plasma cells via flow cytometry and hematoxylin-and-eosin staining.
After completion of study treatment, patients are followed up for up to 1 year.
