NK DLI in Patients After Human Leukocyte Antigen (HLA)-Haploidentical Hematopoietic Stem Cell Transplantation (HSCT)

March 18, 2024 updated by: University Hospital, Basel, Switzerland

Natural Killer Cell Selected T-cell Depleted Donor Lymphocyte Infusions (NK-DLI) in Patients After HLA-haploidentical Allogeneic Stem Cell Transplantation

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: NK cell DLI
Biological: CD3-depleted/CD56+ selected natural killer cells collected from apheresis products
NK DLI products containing >1 10e7 NK cells/kg bodyweight (BW) and < 1 x 10e5 T-cells/kg BW are administered at days +4 (Frankfurt only), and on days +40 and +100 (both centers)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Feasibility of NK-DLI production
Time Frame: At day of transplant (day 0)
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).
At day of transplant (day 0)
Safety of NK DLI Infusion
Time Frame: Day +60 after transplant
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.
Day +60 after transplant

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Efficacy of NK DLI Infusions
Time Frame: 5 years after last NK DLI
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.
