Brief Summary
IL-2 add-back post allogeneic hematopoietic stem cell transplant (HSCT), combined with Sirolimus (SIR), Tacrolimus (TAC) will optimize Treg reconstitution and prevent graft versus host disease (GVHD).

Outcome Measures
Primary Outcomes (1)
Regulatory T Cells (Tregs)/Total CD4+ Cells at Day 30 Post-HCT
Percentage of Treg among blood CD4+ T cells at day 30 after hematopoietic cell transplantation (HCT), to compare to SIR/TAC alone data from a previous trial (median of 16%). The study was designed to capture an increase in regulatory T cells from a median of 16.0% at day +30.
30 days post HCT
Secondary Outcomes (9)
Overall Survival at Day +365
365 days post HCT
Cumulative Incidence of Relapse
1 year post HCT
Cumulative Incidence of Grade II-IV Acute GVHD by Day +100
100 days post HCT
Cumulative Incidence of Chronic GVHD by Day +365
365 days post HCT
Incidence of Non-relapse Death
365 days post HCT
- +4 more secondary outcomes
Other Outcomes (2)
Function of Blood Treg After Allogeneic HSCT
30 days post HCT
Rate of Natural Killer Cell (NK) Reconstitution

Study Arms (1)
GVHD Regimen
EXPERIMENTALGraft versus host disease (GVHD) prophylaxis regimen IL-2 with Sirolimus and Tacrolimus after allogeneic hematopoietic cell transplant (HCT).
Interventions
A subcutaneous injection will be administered 3 times a week (separated by at least 1 day between injections), from day 0 to +90 (+/- 7 days).
Will be administered at 0.01 mg/kg/day (based on ideal body weight) continuous IV infusion or equivalent oral dosing starting on day -3
Orally on day -1. The dose for loading is 12 mg by mouth (PO)
Eligibility Criteria
You may qualify if:
- Patients must have an available 8/8 human leukocyte antigen (HLA)-A, -B, -C, and -DRB1 matched-related or unrelated donor allogeneic hematopoietic peripheral blood stem cell graft.
- Acute myeloid leukemia, myelodysplasia, acute lymphoblastic leukemia, chronic myeloid leukemia, or myeloproliferative neoplasms requiring a matched allogeneic HSCT.
- Acute Leukemia (AML or ALL) must be in complete remission defined as: \<5% marrow blasts with no morphologic evidence of leukemia, no peripheral blasts, marrow \>20% cellular, and peripheral absolute neutrophil count \>1000/µL (platelet recovery is not required).
- Myelodysplasia (MDS) and chronic myeloid leukemia (CML): Must have \<5% marrow blasts.
- Myeloproliferative neoplasms (MPN): Must have \<5% peripheral / marrow blasts.
- Adequate vital organ function:
- Left ventricular ejection fraction (LVEF) ≥ 45% by multi gated acquisition (MUGA) scan or ECHO
- Forced expiratory volume at one second (FEV1), forced vital capacity (FVC), and adjusted diffusing lung capacity oxygenation (DLCO) ≥ 50% of predicted values on pulmonary function tests
- Transaminases (AST, ALT) \< 2 times upper limit of normal values
- Creatinine clearance ≥ 50 cc/min.
- Performance status: Karnofsky Performance Status Score ≥ 80%
- Donor eligibility: Eligible donors will include healthy sibling, relative or unrelated donors that are matched with the patient at HLA-A, B, C, and DRB1 by high resolution typing.
You may not qualify if:
- Active infection not controlled with appropriate antimicrobial therapy
- History of HIV, hepatitis B, or hepatitis C infection
- Anti-thymocyte globulin, alemtuzumab, bortezomib, or cyclophosphamide administered within 14 days before or planned to receive with HCT conditioning or as part of GVHD prophylaxis in the 14 days after HCT.
- Hypersensitivity to recombinant human IL-2
- Chronic lymphocytic leukemia, Hodgkin lymphoma, and non-hodgkin lymphoma are excluded as these malignancies may express the IL-2 receptor and pose a potential growth signal to any present disease.
- Sorror's co-morbidity factors with total score \>4
