The purpose of this study is to determine whether thymic shielding during total body irradiation can be given and whether it will reduce the risk of infections in Fanconi Anemia patients undergoing alternate donor (not a matched sibling) stem cell transplants.

Procedure: Hematopoietic Stem Cell Transplant
Procedure: Thymic Shielding During Radiation
Procedure: Total Body Irradiation
Drug: Cyclophosphamide, Fludarabine
Phase 1
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Study of Thymic Shielding in Recipients of Total Body Irradiation, Cyclophosphamide, and Fludarabine Followed by Alternate Donor Hematopoietic Stem Cell Transplantation in Patients With Fanconi Anemia

Arms Assigned Interventions
Experimental: HSCT Patients
Patients who received total body irradiation (450 cGy [centigray]) with thymic shielding prior to chemotherapy regimen and Hematopoietic Stem Cell Transplant (HSCT)
Procedure: Hematopoietic Stem Cell Transplant
Bone marrow failure may be treated by giving patients stem cells that come from someone else. This is called a stem-cell transplant. As part of the transplant process, patients receive high doses of chemotherapy and/or radiation to treat their underlying disease. As one of its effects, this treatment also kills the healthy stem cells that are already in the marrow. The transplant provides new stem cells for the patient from a healthy donor; that replace the bone marrow and allow the blood counts to recover.
Other Name: Bone Marrow Transplant
Procedure: Thymic Shielding During Radiation
protecting the thymus during total body radiation (450 cGy administered)
Other Name: TBI
Procedure: Total Body Irradiation
Six days before the stem cells are given (day -6), subjects will receive total body irradiation with thymic shielding. Thymic shielding is done by placing a piece of lead on the chest during the irradiation treatment so that the irradiation beams do not go to the thymus.
Other Name: Radiation Therapy, Therapuetic Radiation
Drug: Cyclophosphamide, Fludarabine
Day -5 through Day -2, subjects will receive a chemotherapy regimen of Fludarabine, Cyclophosphamide via central line
Other Name: Cytoxan, Fludara

Detailed Description:
All subjects will be given the same treatment regimen of total body irradiation (TBI), Fludarabine, Cyclophosphamide, and anti-thymocyte globulin (ATG), followed by an alternate donor stem cell transplant. Since this treatment regimen has been given before, without thymic shielding, we will compare the outcomes of these patients with the historical data from subjects who did not receive thymic shielding.

Ages Eligible for Study:   up to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must be less than (<) 18 years of age with a diagnosis of Fanconi anemia.
  • Patients must have an HLA-A, B, DRB1 identical unrelated donor or less than or equal to (≤)1 antigen mismatched related (non-HLA-matched sibling) or <1 antigen mismatched unrelated UCB donor. Patients and donors will be typed for HLA-A and B using serological or molecular techniques and for DRB1 using high resolution molecular typing.
  • Patients with FA must have aplastic anemia (AA), myelodysplastic syndrome without excess blasts, or high risk genotype as defined below.

    • Aplastic anemia is defined as having at least one of the following when not receiving growth factors or transfusions
    • Platelet count <20 x 10^9/L
    • ANC <5 x 10^8/L
    • Hgb <8 g/dL
    • Myelodysplastic syndrome with multilineage dysplasia with or without chromosomal anomalies
    • High risk genotype (e.g. IVS-4 or exon 14 FANCC mutations, or BRCA1 or 2 mutations)
  • Adequate major organ function including

    • Cardiac: ejection fraction greater than (>)45%
    • Hepatic: bilirubin, AST/ALT, ALP <2 x normal
    • Karnofsky performance status >70% or Lansky performance status >50%
  • Women of child-bearing age must be using adequate birth control and have a negative pregnancy test

Exclusion Criteria:

  • Available HLA-genotypically identical related donor
  • History of gram negative sepsis or systemic fungal infection (proven or suspected based on radiographic studies)

  • Pregnant or lactating female
  • Prior radiation therapy preventing use of total body irradiation (TBI) 450 centigray (cGy)
