Brief Summary: In this study the investigators will use busulfan and cyclophosphamide BuCy backbone with the addition of fludarabine as the preparative Stem Cell Transplant SCT regimen As an attempt to improve engraftment rate and reduce infections the investigators are going to incorporate fludarabine in the conditioning regimen The use of a BuCy backbone has been widely used and comparable to total body irradiation and cyclophosphamide CyTBI regimen

Encouraging data on adding fludarabine to the SCT regimen have been reported A fludarabine-based conditioning regimen with adequate immunosuppressive activity could conceivably allow engraftment of stem cells from alternative donors in hematologic malignancies patients with acceptable engraftment rates and low transplant-related mortality Regimen-related toxicity is believed to be a major contributing factor to GVHD Therefore this approach may also lead to reduced GVHD as some investigators have suggested

In an attempt to decrease the rate of viral infection and reactivation the investigators will avoid ATG Thymoglobulin Campath anti-CD52 and instead administer Mycophenolate Mofetil MMF The addition of fludarabine should compensate any increase risk of graft failure with the removal of the ATGCampath The investigators anticipate that the removal of ATGCampath will facilitate immune reconstitution more efficiently after receiving a UCBT
Detailed Description: The following will be given as the conditioning regimen for the transplant

BUSULFAN Busulfan intravenous BUSULFEX dosing will be as follows patients 12 kg 11 mgkgdose IV every 6 hours for 16 doses total patients 12 kg 08 mgkgdose IV every 6 hours for 16 doses Administration and pharmacokinetic monitoring will be performed as per standard practice Anticonvulsants will be given in accordance with standard Blood and Marrow Transplant Program recommendations

CYCLOPHOSPHAMIDE Cyclophosphamide 50 mgkgdose will be given IV on Days -5 - 4 -3 and -2 over 1 hour The total dose to be given over 4 days is 200 mgkg Mesna will be given in accordance with standard Blood and Marrow Transplant

FLUDARABINE Fludarabine will be given IV daily over 1 hour for 3 days Dosing will be as follows for patients 10 kg 13 mgkg for patients 10 kg 40 mgm2 Preparation administration and monitoring will be according to standard practice procedure

POST-TRANSPLANT IMMUNOSUPPRESSION

CSA will begin on Day -3 For children 40 kg the initial dose will be 25 mgkg IV over 2 hours every 12 hours Dose adjustments will be made to maintain levels above 200 ngmL Levels will be done on Day 0 and then as clinical indicated CSA will be tapered per institutional SOP Once the patient can tolerate oral medications and has a normal gastrointestinal transit time CSA will be converted to an oral form
MMF will begin on Day 0 at a dose of 15 mgKg IV or orally TID and will be discontinued on Day 45 unless GVHD is present

CNS Disease Patients with CNS relapse or primary CNS disease that is symptomatic or associated to radiological changes will receive additional irradiation to the craniospinal axis

SUPPORTIVE CARE

Supportive care will be provided as per standard practice of the Blood and Marrow Stem Cell Transplant program at the Texas Childrens Hospital including all prophylactic and therapeutic clinical care issues These practices may be modified if necessary for any individual patient in order to provide optimum care for that particular patient
IVIG Intravenous immunoglobulin 500 mgkg per dose will be given monthly until discontinuation of GVHD therapy and documentation of antibody production
CB-CTLs Patients enrolled in this protocol may also be eligible for infusion of CB-derived multivirus-specific CTL to provide virus-specific immune reconstitution and treatment of viral infections after CBT
