A Phase II Pilot Study of 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: A Multicenter Pediatric Transplantation and Cellular Therapy Consortium (PTCTC) Study (EXCEL Trial)


  • Condition: Other
  • Phase: II
  • ID: NCT04836390

What is the goal of the study?

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. We will also demonstrate the feasibility of performing this trial in a multi-center study. We 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. Primary Objective is to estimate 1-yr relapse free survival in children and young adults with high risk AML receiving haploNK infusions following a halpoHCT.
