Allogeneic Stem Cell Transplantation Followed By Targeted Immune Therapy In Average Risk Leukemia (AML/MDS/JMML)
Acute Myelogenous Leukemia, Myelodysplastic Syndrome, Juvenile Myelomonocytic Leukemia
About this trial
This is an interventional treatment trial for Acute Myelogenous Leukemia focused on measuring Allogeneic Stem Cell Transplantation, Targeted Immune Therapy, Acute Myelogenous Leukemia, Myelodysplastic Syndrome, Juvenile Myelomonocytic Leukemia, AML, MDS, JMML
Eligibility Criteria
Inclusion Criteria:
Disease Status
- AML 1st complete remission (CR) with a matched family donor (excluding Downs Syndrome, acute promyelocytic leukaemia (APL), poor cytogenetics (12p, 5q, -7 and FMS-like tyrosine kinase 3 (FLT3) mutations or duplication t(9;11) and others)) and patients consented to and registered on an upfront AML COG study with a matched family donor)
- AML 1st CR (excluding Downs Syndrome, APL, and chromosome translocation (8;21) or inversion (16) or poor cytogenetics (12p, 5q, -7, FLT3 mutation or duplication t(9;11) and others)) with unrelated donor
- AML 2nd CR
- Myelodysplastic Syndrome (MDS) and ≤ 5% bone marrow myeloblasts at diagnosis (de novo patients only)
- Juvenile Myelomonocytic Leukemia (JMML) and ≤ 5% bone marrow myeloblasts at diagnosis
In regards to disease immunophenotype, disease must express a minimum of ≥10% Cell Differential 33 (CD33) positivity for patients with AML
Organ Function:
Patients must have adequate organ function as defined below:
Adequate renal function defined as:
- Serum creatinine < 1.5 x normal, or
- Creatinine clearance or radioisotope glomerular filtration rate (GFR) 40 ml/min/m2 or > 60 ml/min/1.73 m2 or an equivalent GFR as determined by the institutional normal range
Adequate liver function defined as total bilirubin 2.0 x upper limit of normal (ULN), or serum glutamic-oxaloacetic transaminase (SGOT)(aspartate aminotransferase (AST)) or serum glutamic-pyruvic transaminase (SGPT)(alanine aminotransferase (ALT)) < 5.0 x ULN
Adequate cardiac function defined as:
- Shortening fraction of ≥ 25% by echocardiogram, or
- Ejection fraction of ≥ 45% by radionuclide angiogram or echocardiogram
Adequate pulmonary function defined as:
- Diffusion capacity of the lung for carbon monoxide (DLCO) ≥ 40% by pulmonary function tests (PFT) (Uncorrected)
- For children who are uncooperative, no evidence of dyspnea at rest, no exercise intolerance, and a pulse oximetry > 94% on room air
Exclusion Criteria:
- Patients with active central nervous system (CNS) AML/JMML disease at time of preparative regimen
- Secondary MDS
- Poor cytogenetics (12p, 5q, -7, FLT3 mutation or duplication)
- Female patients who are pregnant (positive human chorionic gonadotropin(hCG))
- Karnofsky <70% or Lansky <50% if 10 years or less
- Age >30 years
- Seropositive for Human Immunodeficiency Virus (HIV)
- Patients consented to and registered on an upfront Children's Oncology Group (COG) AML study with a matched family donor

Experimental
Experimental
Matched Family Donor
Unrelated Donor
Patients will receive a reduced intensity fludarabine (6 days)/busulfan (2 days) conditioning regimen followed by a stem cell transplant from a related family donor using bone marrow or cord blood stem cells. Then followed by Gemtuzumab Ozogamicin, once at about 2-6 months post alloSCT and once at least 2 months after the first dose. Patients with JMML will also receive cis-retinoic acid (Isotretinoin). During and following transplantation patients will receive methylprednisolone for immune suppression. Graft-versus-host-disease (GVHD) prophylaxis will consist of tacrolimus, mycophenolate mofetil and additionally methotrexate in recipients of unrelated adult transplants.
