Allogeneic hematopoietic stem cell transplantation (HSCT) is an established form of treatment for hematological abnormalities.Poor graft function, occurs when there poor donor engraftment. A second infusion of unselected donor hematopoietic stem cells (HSC) can result in improvement, but can potentially increase the incidence of graft versus host disease.CD34+ selected stem cells depleted of T-cells is an attractive alternative for treatment of poor graft function as it may be associated with less Graft versus Host Disease (GVHD) and enhanced count recovery. The investigators are using the Miltenyi CliniMACS device and CD34 cell selection reagents for the preparation of allogeneic hematopoietic progenitor cell (HPC) transplants for patients who have had prior stem cell transplants and require a stem cell "boost" from the original donor.

Intervention Details:
    Biological: G-CSF mobilized CD34+ selected cells for transplantation

    Mobilization of Donor: Following screening and enrollment after informed consent, the donor will receive mobilization therapy with G-CSF (10 ug/Kg S/C daily x5-6 days) using the standard National Marrow Donor Program (NMDP) guidelines.

    CD34+ selection with CliniMACS device: CD34+ cell selection will be performed according to procedures given in the CliniMACS Users Operating Manual and institutional Standard Operating Procedures (SOPs). If the donor's plasma is not available, CliniMACS buffer will be used.

    The Day of CD34+ cell infusion: Immediately after the release tests have been performed and the product passes the release criteria, the patient will receive the final product. No conditioning regimen will be administered prior to cell infusion.

Detailed Description:

This is a single-arm, open label, single institution, compassionate study which will enroll patients who are marginally engrafted and transfusion and/or growth factors dependent after allogeneic hematopoietic stem cell transplant (HSCT) regardless of the underlying disease for which the transplant was performed. Study subjects will receive a "booster" infusion of CD34+ cell selected and T-cell depleted G-CSF mobilized apheresis product from the original stem cell donor in order to improve engraftment. The "booster" infusion will be administered without prior conditioning.


Ages Eligible for Study:   17 Years to 75 Years
Genders Eligible for Study:   Both

Donor Inclusion Criteria:

  • Donors must be eligible and approved for a hematopoietic stem cell graft according to institutional criteria (related donor) or NMDP criteria (volunteer unrelated donor)
  • Donors must be ≥ 17 years old and ≤ 75 years old
  • Donors must be agreeable to receive G-CSF for CD34 cell mobilization and undergo apheresis for the second donation of peripheral blood mononuclear cells (PBMC)
  • Donor must have adequate peripheral venous catheter access for apheresis or must agree to placement of a central catheter
  • The following laboratory tests/evaluations will be performed for all donors registered in the study. Additional evaluations/studies may also be performed by the site as dictated by the donor's clinical situation or standard practice for monitoring normal donors

      • These tests will be obtained, and reported to Emory, within 30 days prior to collection of the CD34+ cell product.

Recipient Inclusion Criteria:

  • Only patients who are experiencing life-threatening hematological insufficiency, following an allogeneic hematopoietic stem cell transplant will be enrolled into this study
  • Patient must be age > 17
  • Must have ≥ 90 % donor cells in the unfractionated peripheral blood based on either XY FISH or standard short tandem repeats (STR)
  • More than 60 days post allogeneic stem cell transplantation and no reversible etiology found after an allogeneic stem cell transplantation
  • Must meet one of the following criteria:

    • platelets < 20,000/ul, absolute neutrophil count (ANC) < 500/ul or
    • transfusion dependent for at least one cell line and/or
    • on growth factor support (G-CSF) without adequate response for 30 days
  • The original HSCT donor must be available, willing, and medically able to undergo G-CSF mobilization and the apheresis procedures
  • Patients must have non-immune mediated graft dysfunction
