Brief summary

Evaluate the safety of natural killer (NK) cell infusion using CD56 monoclonal antibody selected with Miltenyi Biotec system following nonmyeloablative stem cell transplantation (SCT) from mismatched donors. This pilot study will evaluate toxicity including mortality, occurrence of acute graft versus host disease (aGVHD) and other severe toxicity.

Detailed description

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.

Interventions

DEVICENK-CD56

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.

Inclusion criteria

* Patients with who have undergone a non-myeloablative allogeneic transplant, using a 3-5/6 HLA matched sibling donor. Measureable disease is not needed at study entry. * Performance status must be Karnofsky 50-100%. * Donor cellular engraftment of at least 2.5% from the non-myeloablative procedure. * ≤ Grade 2 acute GVHD at time of infusion of NK cell infusion. Patients with treated acute GVHD must be on a stable dose of therapy (no increase in immunosuppressive therapy for the 2 weeks before planned NKI). The dosage/level of immunosuppressive therapy at the time of NKI should be no greater than 1 mg/kg of prednisone daily or mycophenolate 1000 mg bid daily or cyclosporine with a target level of 200 or equivalent. * Estimated survival at least 8 weeks. * Age \> or equal to 18 years of age.

Exclusion criteria

* Pregnant or lactating women, * Patients with other major medical or psychiatric illnesses, which the treating physician feels, could seriously compromise tolerance to this protocol. * Patients who had biopsy proven overall Grade 4 GVHD lasting longer than 7 days, from the non-myeloablative therapy, are not eligible

Participant flow

Recruitment details

21 Patients were recruited through the Adult Bone Marrow Transplant Program at Duke University Medical Center. Recruitment began in April, 2005 and ended in March, 2011. Patients who met the eligibility criteria were approached about the study and informed consent was conducted for those who agreed.

Pre-assignment details

Prior to donor lymphocyte infusion (DLI), disease state was documented: Complete history Physical exam Performance status Routine lab tests Radiographic tests Subjects didn't continue with treatment with disease progression. 2 subjects withdrew consent; 1 had graft versus host disease; 1 died; 1 subject's donor didn't yield enough cells.
