Donor-Derived Ex-Vivo Expanded Natural Killer Cell Infusions in Children and Young Adults With High Risk Acute Myeloid Leukemia Receiving Myeloablative HLA-Haploidentical Hematopoietic Cell Transplant
Sponsor: Michael Pulsipher
Summary
This is a Phase II pilot study to determine the efficacy of three fixed dose (1 x 108/kg) infusions of ex-vivo expanded human leukocyte antigen (HLA)-haploidentical donor natural killer (NK) cells (haploNK) in children and young adults with high risk acute myeloid leukemia (AML) undergoing HLA-haploidentical hematopoietic cell transplant (haploHCT) with a busulfan and cyclophosphamide-based myeloablative conditioning regimen and post-transplant cyclophosphamide (PTCy) for graft versus host disease (GVHD) prophylaxis. The investigators will also demonstrate the feasibility of performing this trial in a multi-center study. The investigators hypothesize that the infusion of haploNK in this setting will facilitate immune reconstitution and decrease relapse rates and infectious complications without increasing GVHD, resulting in improved survival as compared to recent historical cohorts of haploHCT without NK cell infusion.

Donor-Derived Ex-Vivo Expanded Natural Killer Cell Infusions
Peripheral blood (PB) ≤ 450 mL and based on donor weight (minimum 10 ml/kg) will be drawn from the HLA-haploidentical donor at least 16 days before the scheduled day of transplant (Day 0). HaploNK cells will be manufactured from the PB of the donor after co-culture with irradiated feeder cells (IFC) as described in Section 2.4. The recipients will receive three NK cell infusions on Day-1, Day+7 (± 1 day) and Day+42 (up to Day+90) from day of transplant (Day 0).
