Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase Ib/II trials studies the side effects of decitabine/cedazuridine (ASTX727) and venetoclax in combination with ivosidenib or enasidenib, and how well they work in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory). ASTX727 is the combination of a fixed dose of 2 drugs, cedazuridine and decitabine. Cedazuridine may slow down how fast decitabine is broken down by the body, and decitabine may block abnormal cells or cancer cells from growing. Venetoclax may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Enasidenib and ivosidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving decitabine/cedazuridine and venetoclax in combination with ivosidenib or enasidenib may help control acute myeloid leukemia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVE:

I. To determine the safety and tolerability and recommended phase 2 dose (RP2D) of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib (Arm B) for patients with acute myeloid leukemia. (Phase Ib) II. To determine the overall response rate (complete response \[CR\], complete remission with incomplete hematologic recovery \[CRh\], morphologic leukemia-free state \[MLFS\] and partial response \[PR)\] of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib (Arm B) for patients with acute myeloid leukemia. (Phase 2)

SECONDARY OBJECTIVES:

I. To determine duration of response (DOR), event-free survival (EFS), and overall survival (OS).

II.To evaluate occurrence of minimal residual disease (MRD) negative status by multiparameter flow cytometry and molecular evaluation.

III. To determine the overall response rate (CR, CRh, Cri, MLFS and PR)

IV. Characterize the pharmacokinetic (PK) profiles of venetoclax in plasma samples (Phase 1b only)

EXPLORATORY OBJECTIVE:

I. To investigate global gene expression profiles, deoxyribonucleic acid (DNA) methylation profiles, BH3 profiling and other potential prognostic markers to explore predictors of antitumor activity and/or resistance to treatment.

OUTLINE: Patients are assigned to 1 of 2 arms.

ARM A: Patients receive decitabine/cedazuridine orally (PO) daily on days 1-5, venetoclax PO daily on days 1-14, and ivosidenib PO daily on days 1-28. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive decitabine/cedazuridine PO daily on days 1-5, venetoclax PO daily on days 1-14, and enasidenib PO daily on days 1-28. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients with a diagnosis of relapsed or refractory acute myeloid leukemia (AML) (including biphenotypic or bilineage leukemia including a myeloid component or isolated extramedullary AML); OR
* Patients (\> 60 year old) with newly diagnosed AML not eligible for intensive chemotherapy are also eligible
* To be considered not eligible for intensive chemotherapy, participants must be defined by the following: Age 75 years or older, or Age 18 to 74 years with at least one of the following comorbidities:
