Acute Myeloid Leukemia in Remission, de Novo Myelodysplastic Syndrome, Fanconi Anemia
About this trial
This is an interventional treatment trial for Acute Myeloid Leukemia in Remission
Eligibility Criteria
Inclusion Criteria:
- Any patient with FA and bone marrow (BM) failure involving 2 of the following 3 lineages: granulocyte count < 0.5 x 10^9/L, platelet count < 20 x 10^9/L, or hemoglobin < 8 g/dL
- Any patient with FA who requires red blood cell or platelet transfusions because of marrow failure
- Any patient with FA who has a life-threatening BM failure involving a single hematopoietic lineage
- Any patient with FA and pre-existing cytogenetic abnormality including hematopoietic malignancy (acute myeloid leukemia [AML] or myelodysplastic syndrome [MDS]) in morphological remission (defined as absence of circulating blasts and bone marrow blasts < 5% as assessed by morphology); Note that hematopoietic recovery is not required for remission status
- Patients must have a negative cytotoxic cross match with donor
- DONOR: Related, human leukocyte antigen (HLA)-haploidentical donors must be identical for one HLA haplotype and mismatched for any number of HLA-A, -B, -C, DRB1 or DQB1 loci of the unshared haplotype
- DONOR: Unrelated, HLA-matched donors must be matched at HLA-A, B, C, DRB1 and DQB1 by deoxyribonucleic acid (DNA) typing at the highest resolution routinely available at the time of donor selection; a single allele mismatch at HLA-A, B, or C is allowed OR a single DQB1 mismatch is allowed
- DONOR: Bone marrow will be the only allowed hematopoietic stem cell source
- DONOR: Haploidentical donor selection will be based on standard institutional criteria, otherwise no specific prioritization will be made amongst the suitable available donors
Exclusion Criteria:
- Patients having available HLA-matched related donors
- Significant organ dysfunction that would prevent compliance with conditioning, graft-versus-host disease (GVHD) prophylaxis, or would severely limit the probability of survival, such as liver disease/failure (active hepatitis, moderate to severe portal fibrosis/cirrhosis confirmed by biopsy or uncorrectable hepatic synthetic dysfunction), lung disease, or cardiac disease (ejection fraction < 35%, or if unable to obtain ejection fraction, shortening fraction of < 26%; if shortening is < 26% a cardiology consult is required with principal investigator [PI] having final approval of eligibility)
- Human immunodeficiency virus (HIV) seropositive patients
- Fertile females who are unwilling to use contraceptive techniques during and for the twelve months following treatment, as well as females who are pregnant or actively breast feeding
- Fertile males who are unwilling to use contraceptive techniques during and for the twelve months following treatment
- AML/MDS in morphological relapse, defined as having circulating blasts or bone marrow blasts >= 5% as assessed by morphology
- Active infectious disease concerns
- Karnofsky performance score < 50 or Lansky performance score < 40
- DONOR: Donors found to have Fanconi anemia based on chromosomal breakage analysis
- DONOR: Donors who are not expected to meet the minimum target dose of marrow cells (1 x 10^8 nucleated cells/kg recipient ideal body weight [IBW]) or who are unwilling to be bone marrow donors
- DONOR: HIV-positive donors
- DONOR: Donors who are cross-match positive with recipient
- DONOR: Recipient homozygous at mismatched locus; if the recipient is homozygous at HLA-A, B, or C and the donor is mismatched at that locus, the donor should be avoided; exceptions must be discussed with the PI

Patients with a history of hematologic malignancy and HLA-haploidentical donor receive fludarabine phosphate (FLU) intravenously (IV) over 1 hour on days -6 to -2, and undergo TBI on day -1 and allogeneic bone marrow transplant on day 0. Patients then receive CY IV over 1 hour on days 3 and 4, MMF orally (PO) thrice daily (TID) on days 5-35, and CSP IV or PO on days 5-84, with taper until day 180, in the absence of GVHD.
Patients with no history of hematological malignancy and HLA-haploidentical donors receive FLU IV over 1 hour on days -6 to -2, and undergo TBI on day -1 and allogeneic bone marrow transplant on day 0. Patients then receive CY IV over 1 hour on days 3 and 4, MMF PO TID on days 5-35, and CSP IV or PO on days 5-84, with taper until day 180, in the absence of GVHD.
Patients with history of hematologic malignancy and HLA-matched unrelated donors receive FLU IV over 1 hour on days -6 to -2, and undergo TBI on day -1 and allogeneic bone marrow transplant on day 0. Patients then receive CY IV over 1 hour on days 3 and 4, MMF PO TID on days 5-35, and CSP IV or PO on days 5-84, with taper until day 180, in the absence of GVHD.
