Primary Outcome Measures:
  • 6 dose cohorts for safety monitoring. Each cohort is assessed for DLT for one month after autologous cultured CTL infusion prior to enrolling the next cohort. [ Time Frame: 2.5 years estimated ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • If Phase I has successfully shown the target dose to be below the MTD continue enrolling until 38 patients have received the target dose. Patients will be monitored for safety and efficacy. [ Time Frame: 2.5 years estimated ] [ Designated as safety issue: Yes ]

Enrollment: 6

Detailed Description:

Primary Aim: To conduct a Phase 1/2 clinical trial of autologous CTL-mediated immunotherapy in a homogeneous group of patients with AML who have recently received an autologous hematopoietic stem cell transplant. Specifically:

Phase 1: To determine the MTD of autologous AML-reactive cultured CTL in patients with AML who have recently received an AHSCT.

Phase 2: To determine 1 year progression-free survival of the study group vs institutional historical control group composed of a sequential series of recent patients who have received an AHSCT for AML.
