  • Creatinine clearance 30-45 mL/min based on Cockcroft-Gault or Modified of Diet in Renal Disease (MDRD) formular
  • Hepatic disorder with total bilirubin between 1.5 and 3 times the ULN 5. Patient must have a projected life expectancy of ≥12 weeks

Exclusion Criteria13

  • Patient has received treatment with the following:
  • A hypomethylating agent, venetoclax, and/or chemotherapeutic agent for AML, myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia (CMML), or myelodysplastic/myeloproliferative neoplasms (MPS/MPN)

  • Patient is receiving concurrent corticosteroid therapy as an anticancer drug (any dose).
  • Patient has known active CNS involvement with AML. Patients who received intrathecal chemotherapy for prophylaxis of AML in the CNS prior to enrollment may enroll in this study.
  • Creatinine clearance \<30ml/min based on Cockcroft-Gault or MDRD formular.
  • Bilirubin of \>3xULN in the absence of Gilbert's Syndrome.
  • AST and/or ALT \>3 times the ULN.
