Decitabine Alone or in Combination With Venetoclax, Gilteritinib, Enasidenib, or Ivosidenib as Maintenance Therapy for the Treatment of Acute Myeloid Leukemia in Remission

Oral Decitabine-Based Maintenance Therapy in Patients With AML in Remission

This phase Ib trial is to find out the side effects and possible benefits of decitabine alone or given together with venetoclax, gilteritinib, enasidenib, or ivosidenib in treating patients with acute myeloid leukemia that is under control (remission). Chemotherapy drugs, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Venetoclax may stop the growth of cancer cells by blocking a protein called Bcl-2 needed for cell growth. Gilteritinib, enasidenib, and ivosidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving decitabine alone or together with venetoclax, gilteritinib, enasidenib, or ivosidenib may help to control the disease.

II. To assess overall survival (OS) of patients with AML treated with oral decitabine-based combinations as maintenance therapy.

III. To assess event-free survival (EFS) of patients with AML treated with oral decitabine-based combinations as maintenance therapy.

IV. To assess the duration of remission (CRd) of patients with AML treated oral decitabine-based combinations as maintenance therapy.

V. To assess the effects of oral decitabine-based combinations on dynamics of minimal residual disease and their relationship to outcomes.

EXPLORATORY OBJECTIVE:

I. To evaluate RFS in (1) intensive induction cohort and (2) lower intensity induction cohort.

  • Have a negative serum or urine pregnancy test within 10 to 14 days of enrolling
  • Agree to either abstinence or 2 effective contraceptive methods (such as barrier methods or hormonal contraception) throughout the treatment period and up to 30 days after discontinuing treatment
• For male patients with a female partner of childbearing age, they may participate if they agree to either abstinence or 2 effective contraceptive methods throughout the treatment period and up to 30 days after discontinuing treatment
• Ability to understand and sign informed consent

Exclusion Criteria:

• Diagnosis of acute promyelocytic leukemia (APL), AML - M3 by French-American-British (FAB) classification based on morphology, immunophenotype, molecular, or cytogenetics studies
• Diagnosis of AML associated t(15;17) or APL variant. Patients with t(9;22) are also ineligible unless they are unable or unwilling to receive therapy with a tyrosine kinase inhibitor
• Uncontrolled intercurrent illness including, but not limited to active uncontrolled infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Patients with active CNS (central nervous system) disease
• Patients with documented hypersensitivity to any components of the study program
• Females who are pregnant or lactating or intending to become pregnant during the study
• Patients with history of extramedullary AML, except for CNS involvement that is currently controlled, will not be eligible for enrollment
