Biological Therapy in Treating Patients With Advanced Myelodysplastic Syndrome, Acute or Chronic Myeloid Leukemia, or Acute Lymphoblastic Leukemia Who Are Undergoing Stem Cell Transplantation
Study Details
Study Description
Brief Summary
This phase I/II trial is studying the side effects of biological therapy and to see how well it works in treating patients with advanced myelodysplastic syndrome, chronic myeloid leukemia, acute myeloid leukemia, or acute lymphoblastic leukemia. Biological therapies, including immunotherapy, can potentially be used to stimulate the immune system and stop cancer cells from growing. Immunotherapy given to patients who have undergone donor stem cell transplantation may be a way to eradicate remaining cancer cells
Detailed Description
PRIMARY OBJECTIVES:
- To determine the safety and potential toxicities associated with infusing donor CD8+ cytotoxic T lymphocyte (CTL) clones specific for Wilms' tumor (WT1) in patients who have relapsed or at a high risk of relapse post transplant for myelodysplastic syndromes (MDS), chronic myelogenous leukemia (CML), acute myeloid leukemia (AML), or acute lymphoblastic leukemia (ALL).
SECONDARY OBJECTIVES:
-
To determine the in vivo persistence of transferred T cells and assess migration to the bone marrow, a predominant site of leukemic relapse.
-
To determine if adoptively transferred WT1-specific T cells mediate antileukemic activity.
OUTLINE: Donors undergo leukapheresis for stem cell harvest to generate CD8-positive WT1 gene-specific CTL clones at the time of allogeneic stem cell transplantation.
After post-transplantation hematopoietic recovery, patients receive treatment for either highest-risk disease (prophylactically) or relapsed disease.
Highest-risk disease group: Patients receive CD8-positive WT1 gene-specific CTL clones intravenously (IV) over 1-2 hours on days 0, 14, and 28. Beginning 2-4 hours after CTL infusion, patients receive interleukin-2 subcutaneously (SC) twice daily on days 28-42 in the absence of unacceptable toxicity.
Relapsed-disease group: Some patients with evidence of leukemic relapse may receive standard salvage chemotherapy prior to donor CTL infusions and then receive CD8-positive WT1 gene-specific CTL clones and interleukin-2 as in the highest-risk group.
Patients in both groups who have progressive disease after complete or partial response to therapy may be eligible for retreatment with CD8-positive WT1 gene-specific CTL clones.
After completion of study treatment, patients are followed every 3 months for 2 years.

Outcome Measures
Primary Outcome Measures
- Toxicity rate associated with infusing donor CD8+ CTL clones specific for WT1 in patients at high risk for post transplant relapse of CML, AML, or ALL [Up to 4 weeks after the final dose of CTL]
Assessed by Common Terminology Criteria (CTC) version 3.0.
Secondary Outcome Measures
- Relapse of disease [Up to 2 years]
Patients achieving complete remission with chemotherapy and T cell infusions will be followed to determine the duration of response. The proportion of responders will be estimated with associated confidence intervals. Duration of remission will be summarized using time-to-event methods, which will allow estimates to be made while some patients remain in remission.
Eligibility Criteria
Criteria
Inclusion Criteria:

- Pre-transplant: Patients undergoing allogeneic hematopoietic stem cell transplantation for refractory anemia with excess blasts (RAEB), refractory anemia with excess blasts in transformation (RAEB-t), CML beyond chronic phase, AML beyond first remission, Philadelphia chromosome (BCR-ABL)-positive ALL at any stage, any ALL beyond first remission, primary refractory AML or ALL, therapy-related AML at any stage, or acute leukemia at any stage arising in a patient with an antecedent diagnosis of a myelodysplastic or myeloproliferative syndrome (including chronic myelomonocytic leukemia, CML, polycythemia vera, essential thrombocytosis, and agnogenic myeloid metaplasia with myelofibrosis);
-
- Post-transplant: Patients who have relapsed after transplant (morphologic, flow cytometric, cytogenetic and molecular relapse) can be offered enrollment on the protocol and may undergo therapy if it is considered possible to control their disease while waiting for the generation of study therapy
-
- Patients and donors must both express an human leukocyte antigen (HLA)-allele for which it is possible to generate WT1-specific clones for
-
- Patients must be able to provide blood and bone marrow samples required for this protocol
-
Eligibility for Prophylactic Treatment with CD8+ CTL After Transplant (Highest Risk Subgroup): At time of planned treatment, CD8+ CTL specific for WT1 must have been generated and have completed Quality Control (QC) testing
-
- Patients must have had > 5% morphologic blasts detectable in bone marrow or peripheral blood just prior to or at the time of transplant
-
- Patients must have evidence of post transplant recovery of normal hematopoiesis (absolute neutrophil count [ANC] > 500/mm^3) for at least 7 days prior to the initiation of CTL infusions
-
- Patients on immunosuppressive therapy for graft-versus-host disease (GVHD) are eligible for treatment if not receiving corticosteroids or if the dose of corticosteroids can be tapered to =< the equivalent of 0.5 mg/kg/day of prednisone; the patient's symptoms have to remain stable and unlikely to increase to stage III or IV acute GVHD or chronic GVHD is unlikely to progress following the change in immunosuppressive therapy, after an appropriate monitoring period, as deemed by the patients treating physician and the principal investigator
-
Eligibility for Treatment with CD8+ CTL at the Time of Relapse after Transplant (All Others): At time of planned treatment, CD8+ CTL specific for WT1 must have been generated and have completed Quality Control (QC) testing
-
- Patients must have evidence of recurrent disease post transplant; this includes patients with the following:
-
- Morphologic relapse defined as one or more of the following: Abnormal peripheral blasts in absence of growth factor therapy; abnormal bone marrow blasts > 5% of nucleated cells; extramedullary chloroma or granulocytic sarcoma
-
- Flow cytometric relapse defined as: the appearance in the peripheral blood or bone marrow of cells with an abnormal; immunophenotype detected by flow cytometry that is consistent with leukemia recurrence
-

-
DONOR: Both the patient and donor must have an HLA-allele which it is possible to generate WT1-specific clones for
-
DONOR: If a separate leukapheresis via peripheral intravenous access can be arranged, the stem cell donor will undergo leukapheresis to provide the required PBMC no sooner than 2 weeks before or after the stem cell mobilization and harvest
-
DONOR: If a separate leukapheresis is not possible, a portion of the PBMC from the donor's peripheral blood stem cell harvest may potentially be used to generate WT1-specific CTL clones; the feasibility of this option will depend upon the minimal cell dose required for transplantation and the presence of an excess harvest yield and the possibility of generating CTL from this product
-
DONOR: Some donors will be asked to provide both a separate leukapheresis and a portion of the peripheral blood mononuclear cells (PBMC) from the donor's peripheral blood stem cell harvest
-
DONOR: Leukapheresis donors must be age 18 or older
Exclusion Criteria:
-
Patients for whom CD8+ CTL clones specific for WT1 have not been generated in time for planned infusion (these patients can potentially be treated later if CTL become available); Also we will exclude patients whose malignant cells do not over express WT-1, based on direct analysis of a bone marrow sample with > 50% blasts or of leukemia cells isolated for expression analysis; in either case patients will be informed about the availability of other treatment protocols for which they might be eligible
-
Patients with Karnofsky performance status or Lansky play score =< 30%
-
Patients with current stage III or IV GVHD unresponsive to therapy or requiring therapy with anti-CD3 mAb, prednisone > 0.5 mg/kg/day (or corticosteroid equivalent), or other treatments resulting in the ablation or inactivation of T cells (such as other anti-T cell monoclonal antibodies); although the concurrent use of cyclosporine, FK506, or MMF is not strictly an exclusion criteria, attempts should be made to discontinue it if possible
