- Patients must have a calculated creatinine clearance (Cockcroft-Gault equation) > 50 mL/min.
- Patients must have a related or unrelated donor. Sibling donor must be a 6/6 match for human leukocyte antigen A (HLA-A) and HLA-B at intermediate or higher resolution, and DRB1 at high resolution using DNA-based typing; must be willing to donate peripheral blood stem cells; and meet institutional criteria for donation. Unrelated donor must be a 7/8 or 8/8 match at HLA-A, -B, -C, and -DRB1 at high resolution using DNA-based typing; must be willing to donate peripheral blood mononuclear cells (PBSCs); and be medically eligible to donate stem cells according to National Marrow Donor Program (NMDP) criteria.

- Patients must have a Karnofsky performance score (KPS) ≥70 and/or ECOG score of ≤2.
- Patients must have recovered from the toxicities of the most recent induction/consolidation chemotherapy. Recovery is defined by the absence of persistent treatment-related AE of grade 2 or above.

Experimental: Oral azacitidine (CC-486)
Patients on study will receive 300 mg CC-486 for 14 out of 28 days per cycle with dose modification according to the Onureg United States Prescribing Information (USPI). Up to 3 cycles of CC-486 will be allowed, and a minimum of 1 cycle is to be given prior to transplant. Multiple cycles will be allowed only if donor-specific or logistical issues prevent transplantation after the first cycle. CC-486 will be dispensed on day 1 of each treatment cycle and only 1 cycle equivalent is to be dispensed at the beginning of each cycle. Post-transplant maintenance with CC-486 can be started 60 days (range 60-120 days) after hematopoietic progenitor cell infusion which should allow time for count and graft recovery after post-transplant cyclophosphamide (PTCY). The CC-486 maximum preferred pre-emptive dose post-ASCT is 200 mg daily, which will be administered for 14 of 28 days per cycle (max 12 cycles). |
Oral azacitidine is indicated for continued treatment of adult patients with acute myeloid leukemia who achieved first complete remission (CR) or complete remission with incomplete blood count recovery (CRi) following intensive induction chemotherapy and are not able to complete intensive curative therapy.
