Brief Summary: The goal of our study will be to determine the clinical and biological safety of infusing immuno-selected NK Natural Killer CD3-CD56 cells early after allogeneic transplantation with colony stimulating factor G-CSF mobilized peripheral blood stem cells and Reduced Intensity Conditioning RIC as a potential substitute to usual Donor Lymphocyte Infusion DLI that contain the whole range of immune effectors The trial will include several progressive steps dose escalation up to a level compatible with the cost-effectiveness potential of the device and clinical situation and recombinant interleukin-2 r-IL2 activation of selected NK cells in vitro prior to re-infusion
Detailed Description: In the mid 90s it has been shown that donor lymphocyte infusions DLI when given for Chronic Myelocytic Leukemia CML that has relapsed after conventional allogeneic stem cell transplantation SCT result in a high incidence of durable cytogenetic and molecular remissions However regular documented effects are the occurrence of secondary aplasia andor graft-versus-host disease GVHD including the post RIC situation These effects are related to the high content of cytotoxic T cells in the DLI Attempts to deplete CD8 T-cells from DLI have been conducted with promising results but are not totally satisfactory

More recently the infusion of r-IL2 ex-vivo activated autologous or allogeneic NK-selected cells have been studied and the safety established in patients presenting various malignancies

Indeed NK are thoroughly characterized in terms of genotype phenotype and function Although a handful of clinical-grade reagents and devices exist that give access to the human NK cell compartment an immuno-selection device exists that allows for the selection of NK cells from various types of hematopoietic cell collections in view of clinical applications the process produces CD3-CD56 cells in two steps and have been used in the previous experiences
