Dose Escalation Trial of WT1-specific Donor-derived T Cells Following T-Cell Depleted Allogeneic Hematopoietic Stem Cell Transplantation for Patients With Relapsed/Refractory Multiple Myeloma
Multiple Myeloma
About this trial
This is an interventional treatment trial for Multiple Myeloma focused on measuring BUSULFAN, FLUDARABINE, G-CSF, MELPHALAN, RABBIT ATG WT1, PEPTIDE SPECIFIC T CELLS, 12-175
Eligibility Criteria
Inclusion Criteria:
Diagnosis:
- Patient must have multiple myeloma that has either relapsed or remains refractory following autologous stem cell transplantation and patients who have plasma cell leukemia at diagnosis.
- Patients with relapsed multiple myeloma following autologous stem cell transplantation who achieved < partial response following additional chemotherapy or who achieved < PR at 3 months following autologous stem cell transplantation and patients with plasma cell leukemia at diagnosis.
DONOR: Patients must have a healthy HLA matched or mismatched related or unrelated donor who is willing to receive G-CSF injections and undergo apheresis for PBSC collection, or undergo a marrow harvesting procedure.
- HLA-matched related and unrelated donors Patients who have an HLA-matched related or unrelated donor are eligible for entry on this protocol. This will include a healthy donor who is genotypically matched at all A, B, C, DRB1 and DQB1 loci, as tested by DNA analysis.
- HLA- mismatched related and unrelated donors
- Patients who do not have an HLA-matched donor but have a related or unrelated donor who have one antigen or one allele mismatch at the HLA A, B, C, DRB1 or DQB1 loci or who have two mismatches, at HLA-DQB1 and at one other locus, will be eligible for entry on this protocol.
The following inclusion criteria are also required:
- Patients should be ≥ 21, < 73 years old.
- Patients may be of either gender or any ethnic background.
- Patients must have a Karnofsky (adult) or Performance Status > 70%
Patients must have adequate organ function measured by:
- Cardiac: asymptomatic or if symptomatic then LVEF at rest must be > 50% and must improve with exercise.
- Hepatic: < 3x ULN ALT and < 1.5 total serum bilirubin, unless there is congenital benign hyperbilirubinemia.
- Renal: serum creatinine <1.2 mg/dl or if serum creatinine is outside the normal range, then CrCl > 40 ml/min (measured or calculated/estimated) with dose adjustment of Fludarabine for <70ml/min.
- Pulmonary: asymptomatic or if symptomatic, DLCO > 50% of predicted (corrected for hemoglobin)
- Each patient must be willing to participate as a research subject and must sign an informed consent form.
Exclusion Criteria:
- Female patients who are pregnant or breast-feeding
- Active viral, bacterial or fungal infection
- Patient seropositive for HIV-I/II; HTLV -I/II
- Patients who have had a previous malignancy that is not in remission.
- Patients with known hypersensitivity to mouse proteins (murine antibodies in ISOLEX) if receiving SBA-E- bone marrow, or chicken egg products.

Arms of the Study
Arm 1
Experimental
Pts with Mutiple myeloma
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.
