Eligibility Criteria
DISEASE CHARACTERISTICS:
Diagnosis of 1 of the following:
- Acute lymphocytic leukemia (ALL) or acute myeloid leukemia (AML) in first or subsequent remission
- ALL or AML in relapse or primary refractory ALL or AML with a circulating blast count ≤ 10,000/mm^3
- Refractory anemia with excess blasts (RAEB) (RAEB-1 or RAEB-2) if the patient has received induction chemotherapy within the past 60 days
- Appropriate candidate for allogeneic hematopoietic stem cell transplantation (HSCT)
- No CNS involvement refractory to intrathecal chemotherapy and/or standard cranial-spinal radiotherapy
PATIENT CHARACTERISTICS:
- Age 14-55
- Creatinine < 1.5 mg/dL
- Cardiac ejection fraction > 45%
- DLCO corrected > 60% of predicted
- Total bilirubin < 2 times upper limit of normal (ULN) (unless attributed to Gilbert syndrome)
- AST and ALT < 2 times ULN
- Not pregnant or nursing
- Fertile patients must use effective contraception during and for 12 months after transplantation
- HIV negative
- No co-existing disease (other than leukemia or RAEB) that would limit life expectancy to < 3 months
- No uncontrolled infection that, in the opinion of the consulting infectious disease physician, would contraindicate myeloablative HSCT
- No other medical condition that would contraindicate HSCT
- No known hypersensitivity to tacrolimus
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- No prior HSCT
- No concurrent participation in other experimental studies for the prevention of graft-vs-host disease
DONOR CHARACTERISTICS:
- Genotypic or phenotypic HLA-identical related donor
- Able to donate peripheral blood stem cells
- Age > 14 years
- Applicable to male patients only: No female donors who have previously given birth to a male child or have had a pregnancy beyond the first trimester miscarriage or termination of pregnancy or nursing
- No donors who have received blood transfusions
- No CD45 Mutation with aberrant CD45RA isoform expression
Sites / Locations

CONDITIONING: Patients undergo total-body irradiation twice daily on days -10 to -7. Patients also receive thiotepa IV over 4 hours on days -6 and -5 and fludarabine IV over 30 minutes on days -6 to -2. TRANSPLANTATION: Patients undergo infusion of CD34+ enriched allogeneic peripheral blood stem cells (PBSC) followed by CD45RA+ T-cell-depleted allogeneic PBSC on day 0. GRAFT-VS-HOST DISEASE PROPHYLAXIS: Cohort A: Patients receive tacrolimus IV continuously or orally twice daily beginning on day -1 and continuing until day 50 followed by standard taper in the absence of grade II-IV acute GVHD. Cohort B: Patients receive tacrolimus IV continuously or orally twice daily beginning on day -1 and continuing until day 30 followed by rapid taper in the absence of grade II-IV acute GVHD.
