Eligibility Criteria

Inclusion Criteria

  • Diagnosis of
  • acute leukemia in complete remission, or
  • myelodysplasia with 4 or unable to receive myeloablative TBI
  • Use of planned post-transplant maintenance therapy to begin prior to day +75. Patients may receive standard of care maintenance therapies starting at day

+75 or later

  • Patients with a history of hypersensitivity to any of the investigational products
  • Pregnant or breastfeeding as agents used in this study are Pregnancy Category

o C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations, and Pregnancy category D: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks. Females of childbearing potential must have a negative pregnancy test (serum or urine) within 28 days of study registration.

  • Women or men of childbearing potential unwilling to take adequate precautions to avoid unintended pregnancy from the start of protocol treatment through 60 days after the last treatment of VIC-1911 or sirolimus
