This is a phase I/II study of highly selected donor lymphocyte infusions in patients undergoing HLA-haploidentical hemopoietic stem cell transplantation. Patients will be offered "pre-emptive" NK-DLI early after HSCT.

Three schedules of NK-cell infusion will be studied: Basel patients (adult and pediatric) will receive NK-DLI on days +40 and +100 (pre-emptive-late); Frankfurt patients (pediatric) will receive NK-DLI on days +3, +40, and +100 (pre-emptive early). Patients not receiving pre-emptive NK-DLI with loss in donor chimerism or with evidence of minimal residual disease will be offered "therapeutic" NK-DLI.

Primary Outcome Measures:
  • Feasibility of NK-DLI production [ Time Frame: At day of transplant (day 0) ] [ Designated as safety issue: No ]
    The feasibility of the production of expanded NK-cell DLI will be measured. Primary quality measures of the NK cell product are the number of NK cells that can be produced (CD56+/cluster of differentiation 3(CD3)- NK cell goal dose >= 1 * 10e7/kg body weight of recipient) as well as the degree of CD3 T-cell contamination (goal CD3+ T-cell dose < 1 * 10e5 / kg body weight of recipient).

  • Safety of NK DLI Infusion [ Time Frame: Day +60 after transplant ] [ Designated as safety issue: Yes ]
    The safety evaluation regards transfusion associated adverse events (fever, fall in blood pressure, transfusion site reactions, etc) and is evaluated at the time of NK DLI infusion. The primary long-term safety measure is the absence of acute graft-versus-host disease 30 days after the last NK DLI infusion.

Secondary Outcome Measures:
  • Efficacy of NK DLI Infusions [ Time Frame: 5 years after last NK DLI ] [ Designated as safety issue: No ]
    The efficacy of NK DLI infusions will be assessed by evaluation of the rates of overall and disease free survival and the rate of disease relapse. As this is a single arm study, outcome measures assessed will be compared to those of historical controls treated with haploidentical HSCT without NK DLI infusions.
