Name: Total Body Irradiation Type: Radiation
Overall Status
The study proposes the use of Fludarabine, Busulfan, Anti Thymocyte Globulin Rabbit (ATG) and Total Body Irradiation as a preparative regimen before hematopoietic stem cell transplant from unrelated donor peripheral blood stem cells (PBSC). The hypothesis states that the 100 day mortality after this type of transplant will be significantly below the accepted standards, which is about 30% for unrelated donors.
Detailed Description
The primary objective of this study is to evaluate the toxicity (as measured as 100 day survival) after hematopoietic stem cell transplant from an unrelated donor with a novel preparative regimen of Fludarabine, Busulfan, Anti-Thymocyte Globulin, and Total Body Irradiation for pediatric patients with leukemia. The secondary objectives are to evaluate the relapse-free and overall survival after hematopoietic stem cell transplant as well as to evaluate the incidence of acute and chronic graft-versus-host disease after this preparative regimen.
Criteria for eligibility
Healthy Volunteers: No

Criteria: Inclusion Criteria:

- Ages 0-21

- AML in one of the following stages:

- Having preceding myelodysplasia (MDS)

- High Risk cytogenetics

- Requiring > 2 cycles chemotherapy to obtain complete remission

- High allelic ratio FLT3/ITD+,

- Standard risk cytogenetics with positive MRD at end of Induction

- Second or greater CR

- First relapse with < 25% blasts in bone marrow

- With therapy-related AML whose prior malignancy has been in remission for at least 12 months

- ALL in one of the following stages:

- High risk first remission, defined as:

- Ph+ ALL; or,

- MLL rearrangement with slow early response [defined as having M2 (5-25% blasts) or M3 (>25% blasts on bone marrow examination on Day 14 of induction therapy)]; or,

- Hypodiploidy (< 44 chromosomes or DNA index < 0.81); or,

- End of induction M3 bone marrow; or,

- End of induction M2 marrow or MRD>1% with M2-3 marrow or MRD>1% at Day 42.

- High-risk infant ALL defined as age <6 months at diagnosis with MLL (11q23) translocation.

- High risk second remission, defined as:

- Bone marrow relapse < 36 months from induction; or >36 mths if a matched sibling donor is available

- T-lineage relapse at any time; or,

- Very early isolated CNS relapse (<18 months from diagnosis); or,

- Slow reinduction (M2-3 at Day 28) after relapse at any time. − Any third or subsequent CR.

- Biphenotypic or undifferentiated leukemia in any CR or if in first relapse must have < 25% blasts in bone marrow

- MDS at any stage; prior therapies allowed

- CML in chronic or accelerated phase; prior therapies allowed

- Patient also must have the following organ requirements:

- Adequate renal function defined as serum creatinine <2x normal, or creatinine clearance > 40 ml/min/m^2 or 70 ml/min.

- Adequate liver function as defined by total bilirubin less than or equal to 2 times normal and AST and ALT less than or equal to 4 times normal.

- Adequate cardiac function as defined by: shortening fraction > 24% by echocardiogram, or ejection fraction > 30% by radionuclide angiogram.

- Adequate pulmonary function as defined by DLCO, FEV1/FVC > 60% by pulmonary function tests. For children who are uncooperative for PFTs and have no evidence of dyspnea at rest or exercise intolerance, pulse oximetry > 94% on room air is considered acceptable, with a normal chest xray.

- Adequate venous access; a double lumen central vascular access device or its equivalent and an additional PICC line will be required for all patients.

- Women of childbearing potential and sexually active males should use effective contraception while on study.

Exclusion Criteria:

- Inability to give informed consent or assent

- Inability to obtain a suitable donor

- Patient who is HIV-positive

- Patient who has active Hepatitis B

- Patient who is pregnant

- Patient who is otherwise considered unsuitable for transplant at the discretion of the principal investigator.
