Comparing Different Treatment Lengths for Venetoclax in Older People with Newly Diagnosed Acute Myeloid Leukemia (A MyeloMATCH Treatment Trial)
This phase II MyeloMATCH treatment trial compares ASTX727 with standard duration versus shorter duration of venetoclax for the treatment of newly diagnosed acute myeloid leukemia (AML). ASTX727 is a combination of decitabine and cedazuridine. 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 in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Shorter duration venetoclax may be as effective as standard duration venetoclax when given with ASTX727 for the treatment of newly diagnosed AML.

This specimen must have been drawn and processed within 28 days prior to registration. For creatinine clearance formula see the tools on the CRA Workbench https://txwb.crab.org/TXWB/Tools.aspx
- Participants must have adequate cardiac function. Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, must have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, participants must be class 3 or better
- Participants with a known history of human immunodeficiency virus (HIV)-infection must be on effective anti-retroviral therapy at registration and have undetectable viral load test on the most recent test results obtained within 6 months prior to registration, if indicated
- Participants with a known history of chronic hepatitis B virus (HBV) infection must have undetectable HBV viral load while on suppressive therapy on the most recent test results obtained within 6 months prior to registration, if indicated
- Participants with a known history of hepatitis C virus (HCV) infection must have been treated and cured. Participants currently being treated for HCV infection must have undetectable HCV viral load test on the most recent test results obtained within 6 months prior to registration, if indicated
- Participants must not have a prior or concurrent malignancy whose natural history or treatment (in the opinion of the treating physician) has the potential to interfere with the safety or efficacy assessment of the investigational regimen
- Participants must not be pregnant or nursing (nursing includes breast milk fed to an infant by any means, including from the breast, milk expressed by hand, or pumped). Individuals who are of reproductive potential must have agreed to use an effective contraceptive method with details provided as a part of the consent process. A person who has had menses at any time in the preceding 12 consecutive months or who has semen likely to contain sperm is considered to be of "reproductive potential." In addition to routine contraceptive methods, "effective contraception" also includes refraining from sexual activity that might result in pregnancy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) including hysterectomy, bilateral oophorectomy, bilateral tubal ligation/occlusion, and vasectomy with testing showing no sperm in the semen
- Participants must be able to swallow and retain oral medications and have no known gastrointestinal disorders likely to interfere with absorption of oral medications
- Participants must have agreed to have specimens submitted for translational medicine for MRD under MYELOMATCH. * Enrollment to this treatment study requires prior enrollment into the myeloMATCH Master Protocol (MYELOMATCH). Participants enrolled in MYELOMATCH will submit bone marrow samples, peripheral blood samples, and buccal swabs to the Molecular Diagnostics Network (MDNet), the Clinical Laboratory Improvement Act (CLIA) laboratory network for myeloMATCH. Refer to MYELOMATCH for submission requirements and directions. * In addition to the MYELOMATCH specimens, there will be specimens obtained on treatment for this substudy. These specimens will be derived from procedures performed as part of standard assessments in the clinical care and management of AML with material being sent to the MDNet laboratories as specified. After performing the required tests on the specimens, the MDNet laboratories will send the residual material for biobanking and future research. Therefore, participants must be asked for their consent for the biobanking of specimens for future unspecified research. Participants may refuse this, but it is mandatory for sites to ask participants
- Participants must be offered the opportunity to participate in specimen banking
- NOTE: As a part of the OPEN registration process the treating institution's identity is provided in order to ensure that the current (within 365 days) date of institutional review board approval for this study has been entered in the system. * Participants must be informed of the investigational nature of this study and must sign and give informed consent in accordance with institutional and federal guidelines. * For participants with impaired decision-making capabilities, legally authorized representatives may sign and give informed consent on behalf of study participants in accordance with applicable federal, local, and Central Institutional Review Board (CIRB) regulations

PRIMARY OBJECTIVES:
I. To compare whether the proportion of participants with a measurable residual disease (MRD) negative complete remission (CR) at 180 days (6 months) is not more than 12% worse between participants randomized to venetoclax for 14 days versus 28 days per cycle (non-inferiority assessment).
II. If 14 days of venetoclax is found to be non-inferior to 28 days, to test whether the proportion of participants with an MRD-negative CR at 180 days (6 months) after randomization is significantly higher in the 14 days per cycle compared to the 28-days per cycle (superiority assessment).
SECONDARY OBJECTIVES:
I. In each arm, to estimate the frequency and severity of toxicities.
II. In each arm, to estimate CR rates, CR with incomplete count recovery (CRi) (CRi, with and without MRD) rates, event-free survival (EFS), relapse-free survival (RFS), and overall survival (OS) for each of the regimens.
III. In each arm, to use the disease characteristics from MATCHBox to describe mechanisms of resistance (and disease sensitivity) across the treatment arms.
IV. In each arm, to tabulate the number of cycles competed, percent of cycles with at least one dose reduction, and percent of cycles with at least one treatment delay at 180 days (6 months) after randomization.
BANKING OBJECTIVE:
I. To bank specimens for future correlative studies.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM 1: Patients receive decitabine and cedazuridine (ASTX727) orally (PO) once daily (QD) on days 1-5 and venetoclax PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and blood sample collection throughout the study.
ARM 2: Patients receive ASTX727 PO QD on days 1-5 and venetoclax PO QD on days 1-14 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and blood sample collection throughout the study.
After completion of study treatment, patients are followed up periodically for up to 5 years.
