NCT02143830

Brief Summary

The purpose of this study is to determine whether the use of lower doses of busulfan and the elimination of cyclosporine will further reduce transplant-related side effects for patients with Fanconi Anemia (FA). Patients will undergo a transplant utilizing mis-matched related or matched unrelated donors following a preparative regimen of busulfan, fludarabine, anti-thymocyte globulin and cyclophosphamide.

Outcome Measures

Primary Outcomes (1)

  • Graft Failure or Rejection

    Primary non-engraftment is diagnosed when the patient fails to achieve an ANC \>=500/mm3 at any time in the first 28 days post-transplant. If (1) after achievement of an absolute neutrophil count (ANC) \>=500/mm3, the ANC declines to \<500/mm3 for more than 3 consecutive days in the absence of relapse, or, (2) there is absence of donor cells in the marrow and/or blood as demonstrated by chimerism assay in the absence of relapse, a diagnosis of secondary graft failure is made. The patient is not evaluable for graft failure or rejection if recurrence of host MDS is detected concurrently.

    5 years

Secondary Outcomes (1)

  • Post-transplant severe morbidity and mortality

    2 years post-transplant

Other Outcomes (3)

  • Graft Versus Host Disease

    One year

  • Leukemic Relapse

    5 years

  • Secondary malignancies

    5 years

Study Arms (3)

Arm A: Good Risk Patients

EXPERIMENTAL

Patients 18 years old or younger with marrow aplasia or single lineage cytopenias will be receive intravenous busulfan (4 doses x 2 days), cyclophosphamide (4 doses x 4 days) and fludarabine (4 doses x 4 days), as used in our most current study that led to \> 90% survival rates . Busulfan pharmacokinetics will not be used. All patients will receive rabbit ATG (4 doses x 4 days) prior to and granulocyte-colony stimulating factor (G-CSF) after transplant to promote engraftment. Cyclosporine will not be used for GVHD prophylaxis. The source of the stem cells for all patients will be peripheral blood stem cells mobilized by treatment of the donor with G-CSF. T-cell depletion will be performed by positive CD34 selection with the use of the Miltenyi system (CliniMACS device). Enrollment on this arm will include up to 50 patients.

Arm B: Intermediate Risk Patients

EXPERIMENTAL

Patients 18 years old or younger with MDS or AML will receive intravenous busulfan (4 doses x 2 days), cyclophosphamide (4 doses x 4 days) and fludarabine (4 doses x 4 days). Busulfan pharmacokinetics will be used in this arm, as the dose of busulfan is higher. All patients will receive rabbit ATG (thymoglobulin) (4 doses x 4 days) prior to and G-CSF post transplant to promote engraftment. Cyclosporine will not be used for prophylaxis against GVHD. The source of the stem cells for all patients will be peripheral blood stem cells induced and mobilized by treatment of the donor. T-cell will be performed by positive CD34 selection with the use of the Miltenyi system (CliniMACS device). The maximum number of patients enrolled in this arm will be 10.

Arm C: High Risk Patients

EXPERIMENTAL

Patients 19 years old or older with marrow aplasia or MDS or AML will receive intravenous busulfan (4 doses x 2 days), cyclophosphamide (4 doses x 4 days) and fludarabine (4 doses x 4 days). In this study, we will test whether outcomes can be improved, yet engraftment maintained, with a slightly reduced dose of busulfan. Patients will receive rabbit ATG (4 doses x 4 days) prior to and G-CSF post transplant to promote engraftment. Cyclosporine will not be used for GVHD prophylaxis. The source of the stem cells will be peripheral blood stem cells collected from donors treated with G-CSF. T-cell depletion will be performed by positive CD34 selection with the use of the Miltenyi system (CliniMACS device). The maximum number of patients enrolled will be 10.

Interventions

A standard dose of busulfan, associated with excellent outcomes in our previous trial will be used for young patients with marrow aplasia (arm A). A higher dose of busulfan will be used in younger patients with MDS and AML (arm B) to maximize disease control. A lower dose of busulfan will be used in older patients (arm C) to minimize toxicity.

Arm A: Good Risk PatientsArm B: Intermediate Risk PatientsArm C: High Risk Patients

Arms A, B and C - Cytoxan will be given as a 1-2 hour infusion for 4 days. The dose will be adjusted according to patients ideal body weight for obese patients.

All patients will also receive G-CSF post-transplant to foster engraftment.

The source of stem cells for all patients will be peripheral blood stem cells (PBSC) induced and mobilized by treatment of the donor with G-CSF for 4-6 days. T-cell depletion will be uniformly performed by positive CD34 selection with the use of the Miltenyi system (CliniMACS device).
