Brief summary
The purpose of this study is to determine the maximum tolerated dose of alloreactive NK cells that can be transfused following stem cell transplant.
Interventions
Alloreactive NK cells will be purified by a two-step immunomagnetic selection (CD3 depletion followed by CD56 selection) using the CliniMACS device.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Investigate the maximum-tolerated dose (MTD) of highly-purified alloreactive NK cells infused following haplotype-mismatched, KIR ligand-mismatched transplants in patients with refractory hematological malignancies. | through Day 128 |
Secondary
| Measure | Time frame |
|---|---|
| Assess toxicity associated with the infusion of alloreactive NK cells | through Day 128 |
| Assess the risk of acute and chronic GvHD following infusion of alloreactive NK cells. | through Day 128 |
| Assess the feasibility of multiple harvesting and purifying NK cells to the relatively high-doses. | through Day 128 |
| Describe the frequency and type of infections occurring within the first year following transplantation. | through Day 128 |
| Describe immune reconstitution following transplantation. | through Day 128 |
