Brief Summary

This is a phase II trial of T cell receptor alpha/beta depletion (α/β TCD) peripheral blood stem cell (PBSC) transplantation in patients with inherited bone marrow failure (BMF) disorders to eliminate the need for routine graft-versus-host disease (GVHD) immune suppression leading to earlier immune recovery and potentially a reduction in the risk of severe infections after transplantation.

    • Severe aplastic anemia (SAA)
    • Myelodysplastic syndrome (MDS)
    • High risk genotype
    • Immunodeficiency associated with history of recurrent infections
  • Karnofsky performance status ≥ 70% if ≥ 16 years of age or Lansky play score ≥ 50% for patients <16 years of age

    • Adequate pulmonary, cardiac and liver function
    • Voluntary written consent (minor assent if appropriate) prior to the performance of any study related procedures not part of standard medical care

For TBD patients:

• Diagnosis of TBD

  • Age <70 years of age

  • Has one of the following risk factors:

  • Severe aplastic anemia (SAA)

  • Myelodysplastic syndrome (MDS)

    ≥ 50% for patients <16 years of age

  • Adequate pulmonary, cardiac and liver function

  • Voluntary written consent (minor assent if appropriate) prior to the performance of any study related procedures not part of standard medical care

Exclusion Criteria
  • Pregnant or breastfeeding as the treatment used in this study are Pregnancy Category D. Females of childbearing potential must have a negative pregnancy test (serum or urine) within 14 days of study registration

  • Malignant solid tumor cancer within previous 2 years

Donor Selection (Inclusion Criteria): meets one of the following match criteria:

  • an HLA-A, B, DRB1 matched sibling donor (matched sibling)

Cruzi) plus HBV, HCV, WNV, HIV by nucleic acid testing (NAT); and screening for evidence of and risks factors for infection with Zika virus, or per current standard institutional donor screen - must be negative for HIV and active hepatitis B

  • Not pregnant - females of childbearing potential must have a negative pregnancy test within 7 days of mobilization start
