Stem Cell Transplantation for Fanconi Anemia
21. august 2019 oppdatert av: Masonic Cancer Center, University of Minnesota
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
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.

Forhold
Detaljert beskrivelse
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.

Beskrivelse
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)
- Refractory anemia with excess blasts, or leukemia
- Active central nervous system (CNS) leukemia at time of hematopoietic cell transplant (HCT)
- History of squamous cell carcinoma of the head/neck/cervix within 2 years of HCT
- Pregnant or lactating female
- Prior radiation therapy preventing use of total body irradiation (TBI) 450 centigray (cGy)

Eksperimentell: HSCT Patients
Patients who received total body irradiation (450 cGy [centigray]) with thymic shielding prior to chemotherapy regimen and Hematopoietic Stem Cell Transplant (HSCT)
|
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.
Andre navn:
protecting the thymus during total body radiation (450 cGy administered)
Andre navn:
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.
Andre navn:
Day -5 through Day -2, subjects will receive a chemotherapy regimen of Fludarabine, Cyclophosphamide via central line

Number of Patients Who Exhibited Secondary Graft Failure
Tidsramme: Day 100 after hematopoietic cell transplant

Calculated from Day 1 of hematopoietic cell transplant to Day 100 after transplant.
A complication after Bone Marrow Transplant in which the transplanted stem cells do not grow in the recipient's bone marrow and thus do not produce new blood cells.
