Key inclusion & exclusion criteria

Inclusion Criteria:

- Confirmed diagnosis of inherited or acquired severe aplastic anemia (SAA)

- One of the following available donors:

1. HLA-haploidentical relative

2. If recipient is >= 40 years old, may use HLA-matched related donor

3. For recipients with inherited bone marrow failure syndromes (IBMFS) with clear
evidence of same disorder in potential related donors, may use 10/10 matched
unrelated donor

- Recipient and/or legal guardian must sign protocol informed consent

- Donor must be willing to donate bone marrow

- Left ventricular ejection fraction (LVEF) >= 40%. For recipients < 13 years old,
shortening fraction >= 26% may be used instead.

- Bilirubin < 3 x upper limit of normal (ULN) for age, unless patient has Gilbert's

- aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 5 x ULN for age

- For patients >= 13 years old: estimated creatinine clearance > 50 mL/min using
Cockcroft-Gault formula and actual body weight

- For patients >= 1 but < 13 years old: glomerular filtration rate (GFR) estimated by
updated Schwartz formula >= 90 mL/min/1.73 m^2. If estimated GFR is < 90 mL/min/1.73
m^2, 24-hour measured creatinine clearance must be > 50 mL/min/1.73 m^2.

- For patients >= 8 years old, diffusing capacity of the lung for carbon monoxide (DLCO)
(corrected for hemoglobin) > 40%; forced expiratory volume at one second (FEV1) > 50%;
forced vital capacity (FVC) > 50%

- For patients < 8 years old or unable to undergo pulmonary function testing: no
evidence of dyspnea at rest; no need for supplemental oxygen; oxygen saturation > 92%
on room air

- Karnofsky/Lansky status (depending on age) >= 70%

- Females and males of childbearing potential must agree to practice 2 effective methods
of contraception at the same time. If unwilling, they must agree to complete

Exclusion Criteria:

- Previous administration of immunosuppressive therapy for SAA.

- Fanconi anemia. At minimum, this diagnosis must be excluded by diepoxybutane (DEB) or
equivalent testing on peripheral blood or marrow in patients < 30 years old.

- Clonal cytogenetic abnormalities consistent with pre-myelodysplastic syndrome
(pre-MDS) or MDS on bone marrow examination

- Presence of anti-donor antibodies

- Prior allogeneic stem cell transplant

- Prior solid organ transplant

- Uncontrolled bacterial, viral, or fungal infection

- HIV seropositivity

- Active hepatitis B or C infection determined by serology and/or nucleic acid testing

- Pregnancy or active breastfeeding

- Prior malignancies except: resected basal carcinoma or treated cervical carcinoma in
situ; cancer treated with curative intent > 5 years previously. Other prior cancers
will not be allowed unless approved by the PI.
