Summary:

      In an attempt to reduce relapse risk and improve outcomes following haploidentical
      transplantation for patients with high risk hematologic malignancies, the investigators will
      implement several strategies to augment the well documented effect of NK cell alloreactivity
      seen in HLA-mismatched transplantation. These strategies include (1) choosing potential
      haploidentical donors for optimal NK-alloreactivity, (2) utilizing proteasome inhibition
      post-transplant with MLN9708 to both sensitize tumor cells to NK cytotoxicity and protect
      against graft-versus-host disease (GVHD), and (3) eliminating mycophenolate mofetil from the
      post-transplant immunosuppression regimen to improve NK cell reconstitution following
      haploidentical peripheral blood stem cell transplantation.
