Multi-institutional Prospective Phase I Research of Expanded Multi-antigen Specifically Oriented Lymphocytes for the Treatment of VEry High Risk Hematopoietic Malignancies
Catherine Bollard
Summary
This Phase I dose-escalation trial is designed to evaluate the safety of administering rapidly -generated tumor multi-antigen associated -specific cytotoxic T lymphocytes, to HSCT recipients with high risk AML and MDS.
Description
Patients with evidence of high-risk or relapsed or persistent hematopoietic malignancies (for example but not limited to: acute myeloid leukemia and myelodysplastic syndrome (MDS)) will be eligible for this study. Patients with high risk for relapse will be eligible to receive planned infusion of allogeneic TAA-T after HSCT (with high risk AML and MDS who have undergone allo-HSCT and are in a hematologic remission). We will utilize our established protocol for the manufacture of tumor multi-antigen associated specific cytotoxic T lymphocytes. Peripheral blood mononuclear cells will be expose…

Interventions
- BiologicalTumor associated antigen lymphocytes (TAA-T)
TAA-T may be generated from donors or recipients and will be tested for specificity to 3 tumor antigens commonly found in hematological malignancies (WT1, PRAME, and SURVIVIN,). The goal of this cell infusion will be to initiate an immune response to residual leukemia or lymphoma that includes multiple antigens and may prevent tumor evasion (through decreased expression of a single antigen).
