NK Cell infusion using CD56 monoclonal antibody following nonmyeloablative SCT from mismatched donors
NK Cell infusion using CD56 monoclonal antibody following nonmyeloablative SCT from mismatched donors: The cells from leukapheresis will be NK selected using a CD56 antibody and a cell column system provided by Miltenyi Biotec. The target cell dose for each NK cell infusion will be up to 1 X 10(7) CD56+ cells/kg patient weight with less than 0.5 X 10(6) CD3+ cells/kg patient weight. The first NK cell infusion will be administered 6 weeks post transplant in patients who have ≤ grade II aGVHD at the time of infusion. Patients will be evaluated for toxicity and response until 20 weeks after the last NK Infusion.
The use of non-selected donor lymphocyte infusions (DLIs) (to help early immune recovery and induce antitumor response) following nonmyeloablative allogeneic stem cell transplantation (ASCT) is also complicated by the risk of acute graft versus host disease (aGVHD) with 30-40% of patients experiencing grade III-IV aGVHD. Data suggests that the use of natural killer (NK) cells (instead of nonselected DLIs) in this setting may mediate a graft versus tumor (GVT) effect independently of aGVHD.
This pilot study is designed to evaluate the efficacy and toxicity of donor natural killer (NK) cell selection and infusion following nonmyeloablative allogeneic stem cell transplantation from mismatched donors.
