Comparing Post-Transplant Cyclophosphamide as GVHD Prophylaxis to Standard of Care for Acute Leukemia Patients (PTCy-PMAT)
Acute Lymphoblastic Leukemia (ALL) in Complete Remission, Acute Myeloid Leukemia (AML) in Remission
About this trial
This is an interventional prevention trial for Acute Lymphoblastic Leukemia (ALL) in Complete Remission focused on measuring Sibling Donor Transplant, Allogeneic hematopoietic cell transplantation, GvHD Prophylaxis, Myeloablative regimen
Eligibility Criteria
Inclusion Criteria:
- Patients with Acute Leukemias (AML, ALL) in morphologic complete remission with or without hematologic recovery
- Patients must have a fully matched (8/8) related donor willing to donate peripheral blood stem cells and must meet institutional criteria for donation
- Planned Myeloablative conditioning regimen
- Cardiac function: ejection fraction at rest ≥ 50% by MUGA or TTE
- Estimated creatinine clearance greater than 50 mL/minute
- Pulmonary function: DLCO ≥ 50% (adjusted for hemoglobin), and FVC and FEV1 ≥ 50%
- Liver function: total bilirubin < 2x the upper limit of normal (unless elevated bilirubin is attributed to Gilbert's Syndrome) and ALT/AST < 2.5x the upper normal limit
- Signed informed consent
Exclusion Criteria:
- Karnofsky or Lansky Performance Score < 70%2.
- Active disease
- Patients with uncontrolled bacterial, viral or fungal infections

- History of uncontrolled autoimmune disease or on active treatment
- Patients with prior malignancies,except resected non-melanoma skin cancer or treated cervical carcinoma in situ; cancer treated with curative intent ≥ 5 years previously will be allowed; cancer treated with curative intent < 5 years previously will not be allowed.

Active Comparator
Arm 1: Intervention
Arm 2: Standard of Care
Peripheral blood matched related donor HCT, using myeloablative conditioning regimen (IV Busulfan/IV Fludarabine for AML, IV VP16/TBI for ALL) HCT with cyclophosphamide, and oral tacrolimus (or another calcineurin inhibitor if intolerant for tacrolimus) for GVHD prophylaxis. Cyclophosphamide will be given at a dose of 50 mg/kg/day IV on Day +3 and Day +5 post stem cell infusion (only 2 doses).
