Study Description

Brief Summary:

This is a single arm, total body irradiation (TBI) trial. All patients will be prescribed TBI 300 cGy with the goal of evaluating secondary endpoints.

Condition or disease	Intervention/treatment	Phase
Fanconi Anemia	Drug: Cyclophosphamide; Drug: Fludarabine; Procedure: Total Body Irradiation; Procedure: Bone Marrow Transplantation; Drug: Mycophenolate Mofetil; Drug: Sirolimus	Phase 2; Phase 3

Detailed Description:

Study Treatment: Patients will receive voriconazole (antifungal therapy) by mouth beginning 1 month prior to conditioning therapy, if possible. 1) The subject is to receive total body irradiation (300 cGy) with thymic shielding; it will be given six days before the stem cells are given (day -6). 2) Day -5 through Day -2, subjects will receive a chemotherapy regimen of Fludarabine and Cyclophosphamide via central line (i.e. Hickman or Broviac). Starting Day -3, patients will receive sirolimus therapy with a taper commencing on day +180 and also mycophenolate mofetil (MMF) through day +30 or for 7 days after engraftment, whichever day is later, if no acute graft-versus-host disease (GVHD). 4) If the subject is receiving bone marrow or "peripheral" stem cells (cells collected from the donor's arm via a cell separator), on the day of transplantation, the stem cells taken from the donor will be put into a machine which will separate the lymphocytes (the cells that cause graft-versus-host disease [GVHD]) from the stem cells. If the subject is receiving an umbilical cord blood, the lymphocytes will not be removed because the risk of GVHD is not as high. Otherwise all patients will receive the same treatment. The stem cells are given as an infusion into the subject's existing catheter over 1-2 hours on day 0.5. On the day after transplant (day +1) subjects will be given G-CSF to stimulate the growth of the transplanted cells. 6. While receiving treatment and until the subject's blood counts recover he/she will have daily blood tests, and several bone marrow biopsies and aspirates. After recovery, subjects will be seen once a month for a health assessment and blood tests until at least 3 months after the cells have been infused. Additional blood tests or assessments may be done as medically indicated.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Treatment with TBI; Patients treated with total body irradiation, Fludarabine, Cyclophosphamide, Bone Marrow Transplantation, Mycophenolate Mofetil, and Sirolimus.

Drug: Cyclophosphamide; Day -5 through Day -2, subjects will receive chemotherapy of Cyclophosphamide via central line (i.e. Hickman or Broviac),10 mg/kg intravenously (IV); Other Name: cytoxan; Drug: Fludarabine; 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); Other Name: fludara; Procedure: Total Body Irradiation; 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.; Other Name: Radiation Therapy, Therapeutic radiation; Procedure: Bone Marrow Transplantation; 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.; Other Name: Stem Cell transplantation; Drug: Mycophenolate Mofetil; 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).; Other Name: MMF; Drug: Sirolimus; 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.; Other Name: Rapamycin
