Dose Escalation Trial of WT1-Sensitized T Cells for Residual or Relapsed Leukemia After Allogeneic Hematopoietic Progenitor Cell Transplantation

Eligible patients who consent to enter this trial and for whom WT1 sensitized T cells have been generated in vitro, will receive a single dose of allogeneic WT1-sensitized T cells by bolus intravenous infusion. In this phase I trial, 6 dose levels of T cells will be evaluated, in sequential groups of 3 patients. Dose Escalation will be based on the incidence and severity of toxicities.
