Brief Summary

Recent studies of conventional chemotherapy for infants with high-risk hematologic malignancies show that the long-term disease-free survival is low. Although blood and marrow stem cell transplantation using an HLA identical sibling has improved the outcome for these children, less than 25% have this donor source available. Another option is haploidentical transplantation using a partially matched family member donor (i.e. parental donor). Although haploidentical transplantation has proven curative for some patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including infection and graft versus host disease (GVHD). Building on prior institutional trials, this study will provide patients a haploidentical graft depleted of T lymphocytes using the investigational device, CliniMACS selection system. One week after the transplant procedure, patients will also receive an infusion of additional donor derived white blood cells called Natural Killer (NK) cells in an effort to decrease risks for rejection of the graft, disease relapse, and regimen related toxicity. The primary objective of the study is to evaluate 1 year survival in infants with high risk hematologic malignancies who receive this study treatment.

Outcome Measures

Primary Outcomes (1)

  • One-year Survival

    The one-year survival of infants with high-risk hematologic malignancies who receive a haploidentical transplant procedure using a total body irradiation (TBI)-excluding conditioning regimen followed by an HLA-nonidentical family donor hematopoietic stem cell (HSC) graft depleted of T cells ex vivo using the CliniMACS CD34+ selection system, with a subsequent infusion of donor NK cells purified ex vivo using the CliniMACS CD3+ depletion and CD56+ enrichment system. The Kaplan-Meier estimate for one-year survival is reported.

    One year after transplant

Secondary Outcomes (15)

  • Number of Transplant-Related Adverse Outcomes: Regimen-Related Mortality

    100 days post-transplantation

  • Number of Transplant-Related Adverse Outcomes: Engraftment Failure

    100 days post-transplantation

  • Number of Transplant-Related Adverse Outcomes: Fatal Acute Graft-Versus Host Disease (GVHD)

    100 days post-transplantation

  • Number of Incidences of Chronic GVHD.

    Up to 5 years after transplant

  • Factors Affecting One-year Survival: Median Age of Donor at HSCT

    Up to one year after transplant

  • +10 more secondary outcomes

Study Arms (1)

Study Participants

EXPERIMENTAL

Participants who meet the eligibility criteria for this study. Donor cells will be obtained using the Miltenyi Biotec CliniMACS device. Interventions: Chemotherapy and antibodies, allogeneic stem cell transplantation.

Drug: Chemotherapy and antibodiesDevice: Miltenyi Biotec CliniMACSProcedure: Allogeneic stem cell transplantation

Interventions

Study participants will receive a non-TBI based preparative regimen consisting of Cyclophosphamide, fludarabine, thiotepa, melphalan, and muromonab-CD3 (OKT3) followed by an infusion of a T-lymphocyte depleted haploidentical hematopoietic stem cell graft. Seven days posttransplant, participants will receive an infusion of additional donor derived cells called NK cells.

Limitations and Caveats

The study was limited due to the unavailability of the study drug OKT3 beginning in June 2011. The study was temporarily closed to accrual. Because OKT3 is still unavailable, the study was formally closed to accrual in March 2015.
