Brief Summary

This phase Ib/II trial studies the effects of ASTX727 (decitabine and cedazuridine) in combination with venetoclax in treating patients with higher-risk acute myeloid leukemia patients who do not have a change in the gene called fms-like tyrosine kinase 3 (FLT3). Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Cedazuridine is an enzyme inhibitor. It helps to increase the amount of decitabine in the body so that the medication will have a greater effect. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. Venetoclax may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Venetoclax and decitabine are commonly given together for older patients with AML ASTX727 (a pill form of decitabine + cedazuridine) has been found to be equal to decitabine (given intravenously), and this part of the study is to confirm that venetoclax and ASTX727 is as safe as venetoclax and decitabine given intravenously. This study allows for lowering doses of study drugs to assure the dose chosen for the randomized study (second portion of this trial) is safe and tolerable for people. Giving ASTX727 in combination with venetoclax may help in the treatment of patients with higher-risk acute myeloid leukemia.

You may not qualify if:

  • Favorable or intermediate risk AML as defined by 2017 ELN criteria
  • Presence of FLT3 TKD or FLT-ITD mutations
  • Inability to tolerate oral medication or keep a pill diary
  • Active documented central nervous system (CNS) leukemia

  • Patients with uncontrolled intercurrent illness
  • Patients with psychiatric illness/social situations (including substance abuse) that would limit compliance with study requirements
  • Pregnant women are excluded from this study because venetoclax and ASTX727 have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with venetoclax, breastfeeding should be discontinued if the mother is treated with venetoclax. These potential risks may also apply to other agents used in this study
  • Previous exposure to either venetoclax or \> 1 cycle of DNMTi (e.g. azacitidine, decitabine, ASTX727, CC486)
  • Active, uncontrolled infection as determined by the investigator. Patients with infection under active treatment and controlled with antibiotics are eligible
  • Any condition deemed by the investigator to make the patient a poor candidate for clinical trial and/or treatment with investigational agents
