Summary

This study is being done to learn whether a new method to prevent rejection between the donor immune system and the patient's body is effective.

Conditions

Interventions

TypeNameDescription
RADIATIONHyperfractionated total body irradiationHyperfractionated 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).
DRUGThiotepaThiotepa 5 mg/kg IV
DRUGCyclophosphamideCyclophosphamide 60 mg/kg IV
DRUGBusulfanBusulfan (adult/ped dose)
DRUGFludarabineFludarabine 25 mg/m2 IV
DRUGMelphalanMelphalan 70 mg/m2 IV
DRUGClofarabineClofarabine 20-30 mg/m2 IV
PROCEDUREHPC(A) stem cell allograftAll 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.
DRUGRituximabRituximab 200 mg IV flat dose
DEVICERabbit antithymocyte globulinRabbit 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.
