  Purpose

Experimental and clinical data suggest that alloreactive NK cells can reduce the risk of graft-rejection, GvHD and leukemic relapse after HLA-mismatched transplantation. The effectiveness of allogeneic NK cells is a function of HLA-differences between donor and recipient that give rise to NK cell clones which do not express inhibitory receptors matching for the HLA molecules of the recipient. Aim of the study is to evaluate cellular therapy with alloreactive, IL-2 activated NK cells after transplantation of T-cell depleted stem cell grafts from one haplotype mismatched family donors in patients with hematological malignancies.

Primary Outcome Measures:
  • To evaluate feasibility and safety of alloreactive CD56+/CD3- donor NK cells after one haplotype mismatched transplantation [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    To evaluate feasibility and safety of cellular immunotherapy with purified alloreactive CD56+/CD3- donor NK cells after one haplotype mismatched hematopoietic stem cell transplantation in patients with high risk hematological malignancies who lack an HLA-identical donor.


Secondary Outcome Measures:
  • transplant related mortality [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    The investigation of transplant related mortality (incidence of veno occlusive disease; incidence and type of infectious complications).

  • effectiveness [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    To evaluate the effectiveness of the therapy (relapse rate; disease free survival; MRD monitoring).

  • technical aspects of the cell separation procedure [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    To investigate technical aspects of the cell separation procedure (problems of stem cell mobilization; yield, viability, sterility and purity of the CD34+ and CD56+CD3- cell fraction; log CD3 depletion; in vitro anti-leukemic activity of the CD56+CD3- cell fraction).

  • stable engraftment of haploidentical stem cell grafts can be achieved after conditioning with total body irradiation, thiotepa, fludarabine and OKT3 and subsequent transfer of megadoses of positively selected CD34+ stem cells and CD56+CD3- NK-cells. [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Graft rejection is defined as neutrophils < 0.5 x 10e9/l on day+28 post transplantation.

Arms Assigned Interventions
Experimental: HaploTransplant with NK cells
Haploidentical transplantation of mega-dose CD34+ hematopoetic stem cells with transfer of CD56+CD3-NK cells at day +2
Biological: Haploidentical transplantation with donor NK cells
Pat received a myeloablative conditioning regimen with 12 Gy total-body irradiation in six single doses from day -11 to day -9, thiotepa (5mg/kg/d) on days -8 and -7, fludarabine (40mg/m2/d) from day -6 to day -3, and OKT-3 (5mg/d) from day -5 to day +3. The stem cell graft was aimed to contain > 8 x 10e6 CD34+ cells/kg and < 5 x 10e4 CD3+ cells/kg. A minimum of 1 x 10e7 CD56+CD3- NK cells/kg will be transferred on days +2.
