Pilot Study of Haploidentical Natural Killer Cell Infusions for Poor Prognosis Non-AML Hematologic Malignancies

All participants will receive a 4 day regimen of chemotherapy (clofarabine, cyclophosphamide, and etoposide) followed by an infusion of HLA partially matched family member donor NK cells processed through the use of the investigational CliniMACS device. Interleukin-2 (IL-2) will be given three times per week post-infusion for a minimum of 2 weeks. IL-2 administration will continue until donor NK cells are no longer detectable in the recipient, and, at that time, will be discontinued
