Abstract

Vaccination with dendritic cells (DCs) as professional antigen presenting cells generated from autologous leukemic blasts might elicit anti-leukemic T cell responses in patients with acute myeloid leukemia (AML). To test this hypothesis, autologous AML-DC were generated under good manu-facturing practice (GMP) conditions and injected s.c. into five AML patients up to four times at a biweekly interval. No severe adverse side effects were observed. Three patients remained in a stable condition for 5.5-13 months and two patients died from rapidly progressive AML. Compared to the initial T cell frequency, enzyme linked immunosorbent spot (ELISPOT) assays revealed a significant increase of granzyme B releasing CD8+ T cells specifically recognizing the PRAME derived peptide (ALYVDSLFFL), a leukemia associated antigen expressed by AML blasts. The cytokine levels in the serum of vaccination AML patients as assessed by cytokine bead assay changed over the period of vaccination to an elevated type 1 T helper cell pattern. Interferon γ production by CD4+ T helper cells increased during vaccination. In summary, we demonstrated that autologous AML-DC vaccination is well tolerated and can result in an enhanced and specific response of cytotoxic T cells in AML patients.
