Patients will undergo a preparative regimen with busulfan, melphalan, fludarabine, and anti-thymocyte globulin (ATG), and a T cell depleted stem cell transplant from a histocompatible related or unrelated donor. Hematopoietic stem cell donors for this trial will include individuals who are 10/10 HLA matched or one antigen or allele mismatched at the HLA-A, B, C, DRB1 or DQB1 locus, as defined by high resolution methods .Donors who are 8/10 HLA matched with an antigen or allele mismatched at HLA-DQB1 and at one other locus will also be eligible for the trial. The administration of WT1-specific cytotoxic T cells (WT1 CTLs) post transplantation is integrated to induce complete remissions in patients with residual disease and to decrease the rate of relapse following the allogeneic transplant.
Biological: anti-thymocyte globulin (ATG)
Procedure: a T cell depleted stem cell transplant
- assess the toxicities [ Time Frame: 21 days ]DLT will be defined as a grade III or greater toxicity developing within 3 weeks of the T cell infusion, as graded by the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4 or new development of grade II-IV acute GVHD within 3 weeks of the T cell infusion that requires treatment with systemic glucocorticosteroids. Patients will be evaluated for 21 days for grade III or greater toxicities.
- maximum tolerated dose (MTD) [ Time Frame: 1 year ]Patients will also be monitored for secondary or immune-mediated graft rejection and or onset of grade II-IV acute GVHD following the administration of WT1-specific T-cell infusions. Because patients may still have transplantation associated cytopenia or may have residual disease that may be associated with cytopenias, hematologic toxicity will be excluded in assessing DLT. All patients will be observed for a minimum of 3 weeks after the first WT-1 peptide sensitized T-cell infusion before the dose can be escalated.
- serologic response [ Time Frame: 2 years ]In addition, patients will be monitored for serologic responses of their myelomas. The time at which the response was achieved will be recorded for all patients and summarized by dose level. The data derived from these studies will provide an initial assessment of the effects of the T cell infusions.
- survival [ Time Frame: 2 years ]To quantitate the number of WT1-specific T cells in the blood and marrow at defined intervals post infusion
