Treatment with TBI
EXPERIMENTALPatients treated with total body irradiation, Fludarabine, Cyclophosphamide, Bone Marrow Transplantation, Mycophenolate Mofetil, and Sirolimus.
Interventions
Day -5 through Day -2, subjects will receive chemotherapy of Cyclophosphamide via central line (i.e. Hickman or Broviac),10 mg/kg intravenously (IV)
Day -5 through Day -2 prior to transplant; subjects will receive chemotherapy of Fludarabine via central line (i.e. Hickman or Broviac),35 mg/m\^2 intravenous (IV)
total body irradiation (300 cGy) with thymic shielding will be given six days before the stem cells are given (day -6). 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.
A target of 5 \* 10\^6/kg and a minimum of 4 \* 10\^6 CD34+ cell/kg recipient weight will be collected by apheresis and used for transplant. In most cases this dose will be recovered in a single apheresis; however, a second or rarely third apheresis performed on the following days may be required to achieve the minimum dose.
Patients will receive MMF therapy beginning on day -3 through day +30 or for 7 days after engraftment, whichever day is later, if no acute graft-versus-host disease (GVHD). Engraftment is defined as 1st day of 3 consecutive days of absolute neutrophil count \[ANC\] \> 0.5 \* 10\^9/L. MMF will be given at a dose of 15 mg/kg/dose every 8 hours by mouth(to a maximum dose of 1 gram).
Sirolimus will be administered starting at day -3 with 8mg-12mg mg oral loading dose followed by single dose 4 mg/day with a target serum concentration of 3 to 12 mg/mL by high-performance liquid chromatography (HPLC). Levels are to be monitored 3 times/week in the first 2 weeks, weekly until day +60, and as clinically indicated until day +100 post-transplantation. In the absence of acute GVHD sirolimus may be tapered starting at day +100 and eliminated by day +180 post-transplantation.
Eligibility Criteria
You may qualify if:
- Meeting the definition of standard risk or high risk Fanconi anemia as defined in the next two sections:
- Standard risk patients must be \<18 years of age with a diagnosis of Fanconi anemia with 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 \* 10\^9/L
- ANC \<5 \* 10\^8/L
- Hemoglobin \<8 g/dL
- Myelodysplastic syndrome (MDS) 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)
- High risk patients must have one or more of the following high risk features:
- Advanced MDS (≥ 5% blast) or acute leukemia
- Require additional HSCT for graft failure
- History at any time of systemic fungal or gram negative infection
- Severe renal disease with a creatinine clearance \<40 mL/min
- Age \> 18 years
- Very high risk patients must have Advanced MDS (≥ 5% blast) or acute leukemia after initial hematopoietic stem cell transplant (HSCT)
- +7 more criteria
You may not qualify if:
- Available HLA-genotypically identical related donor in standard risk patients.
- Active central nervous system (CNS) leukemia at time of study enrollment.
- History of squamous cell carcinoma of the head/neck/cervix within previous 2 years.
- Prior radiation therapy that prevents further total body irradiation (TBI).
