Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Radiation, Thiotepa & Cyclophosphamide
Hyperfractionated TBI is administered by a linear accelerator at a dose rate of <20 cGy/minute. Doses of 125 cGy/fraction are administered at a minimum interval of 4 hours between fractions, three times/day for a total of 11 or 12 doses (1,375 or 1,500 cGy) over 4 days (days -9 through -6).
Thiotepa 5 mg/kg IV
Cyclophosphamide 60 mg/kg IV
All patients will receive anti-thymocyte globulin based conditioning followed by a G-CSF mobilized, peripheral blood hematopoietic progenitor cell HPC(A) product depleted of TCR-α/β+ Tlymphocytes using the CliniMACS system.
Rituximab 200 mg IV flat dose
Rabbit antithymocyte globulin dosing per nomogram. This dynamic nomogram is based on absolute lymphocyte count at the start of conditioning and can result in either 2 or 3 day ATG administration. If a patient requires 2 day administration the subjequent chemotherapies may be moved forward by one day at the treating physician's discretion.
Experimental: Busulfan, Fludarabine & Melphalan
All patients will receive anti-thymocyte globulin based conditioning followed by a G-CSF mobilized, peripheral blood hematopoietic progenitor cell HPC(A) product depleted of TCR-α/β+ Tlymphocytes using the CliniMACS system.
Rituximab 200 mg IV flat dose
Rabbit antithymocyte globulin dosing per nomogram. This dynamic nomogram is based on absolute lymphocyte count at the start of conditioning and can result in either 2 or 3 day ATG administration. If a patient requires 2 day administration the subjequent chemotherapies may be moved forward by one day at the treating physician's discretion.

Fludarabine 25 mg/m2 IV
Melphalan 70 mg/m2 IV
Experimental: Clofarabine, Thiotepa & Melphalan
Thiotepa 5 mg/kg IV
All patients will receive anti-thymocyte globulin based conditioning followed by a G-CSF mobilized, peripheral blood hematopoietic progenitor cell HPC(A) product depleted of TCR-α/β+ Tlymphocytes using the CliniMACS system.
Rituximab 200 mg IV flat dose
Rabbit antithymocyte globulin dosing per nomogram. This dynamic nomogram is based on absolute lymphocyte count at the start of conditioning and can result in either 2 or 3 day ATG administration. If a patient requires 2 day administration the subjequent chemotherapies may be moved forward by one day at the treating physician's discretion.
