Acute Myeloid Leukemia, Blasts Under 5 Percent of Bone Marrow Nucleated Cells, EBV-Positive Neoplastic Cells Present, Elevated WT1, HLA-A*0201 Positive Cells Present
Conditions
Brief summary
This phase I/II trial studies the side effects of laboratory-treated (central memory/naive) cluster of differentiation 8+ T cells (autologous Wilms tumor \[WT\]1-T cell receptor \[TCRc\]4 gene-transduced CD8-positive central memory T-cells \[TCM\]/naive T cells \[TN\] lymphocytes) and how well it works in treating patients with acute myeloid leukemia that is newly diagnosed or has come back. Genetically modified therapies, such as autologous WT1-TCRc4 gene-transduced CD8-positive TCM/TN lymphocytes, are taken from a patient's blood, modified in the laboratory so they specifically may kill cancer cells with a protein called WT1, and safely given back to the patient. The genetically modified T-cells have genes added in the laboratory to allow them to recognize leukemia cells that express WT1 and kill them.
Detailed description
PRIMARY OBJECTIVES: I. Determine the safety/potential toxicities associated with treating high-risk acute myeloid leukemia (AML) patients with autologous CD8+ T cells (polyclonal Tn and Tcm cells; Epstein-Barr virus-specific T cells \[Tebv cells\]) that have been genetically-modified to express a high affinity WT1-specific TCR (TCRC4). II. Determine the feasibility of reproducibly treating high-risk AML patients with autologous CD8+ T cells (polyclonal TN and TCM cells; Tebv cells) that have been genetically-modified to express a high affinity WT1-specific TCR (TCRC4). III. Determine and compare the in vivo persistence in blood and at the primary tumor site (e.g. bone marrow, chloroma) of transferred autologous CD8+ T cells (polyclonal TN and TCM cells; TEBV cells) that have been genetically-modified to express a high affinity WT1-specific TCR (TCRC4). EXPLORATORY OBJECTIVES: I. Determine whether adoptively transferred autologous TCRC4-transduced CD8+ cells have anti-tumor activity in patients with acute myeloid leukemia. Ia. In patients with measurable minimal residual disease (MRD) at the time of infusion of TCRC4-transduced CD8+ cells, changes in leukemic tumor burden will be measured by morphology, flow cytometry, cytogenetics/fluorescence in situ hybridization (FISH) and/or molecular testing at baseline and after infusion of T cells. Ib. In all patients (those with or without measurable tumor burden prior to T cell transfer, including patients who convert to MRD-negative status during consolidation), the probability of relapse, disease-free survival and overall survival of patients receiving TCRC4-transduced CD8+ cells will be compared with patients in the observation arm. II. Determine and compare the migration to the primary tumor site of subsets of the adoptively transferred autologous TCRC4-transduced CD8+ T cells (polyclonal TN and TCM cells; TEBV cells). III. Determine and compare the in vivo functional capacity of transferred polyclonal autologous TCRC4-transduced CD8+ TCM, TN cells and TEBV CD8+ cells. OUTLINE: Beginning 4 weeks after completion of last course of consolidation chemotherapy, patients receive autologous WT1-TCRc4 gene-transduced CD8+ TCM/TN lymphocytes intravenously (IV) over 1-4 hours on day 0 and again after a minimum of 3 weeks. Beginning 6 hours after the second infusion of T cells, patients also receive aldesleukin subcutaneously (SC) twice daily (BID) for 14 days in the absence of disease progression or unacceptable toxicity. Patients who have clinically benefitted from T cell therapy may receive additional infusions of T cells and aldesleukin at the discretion of the principal investigator (PI) and the attending physician. After completion of study treatment, patients are followed up weekly for 4 weeks, at 2, 3, 6, and 12 months, and then annually for 14 years thereafter.
