This phase I trial tests the safety, side effects and effectiveness of adding ascorbate to standard of care treatment with azacitidine and venetoclax for the treatment of newly diagnosed acute myeloid leukemia. Ascorbate, also known as “vitamin C”, nutrient that the body needs in small amounts to function and stay healthy. Ascorbate helps fight infections, heal wounds, and keep tissues healthy. It is an antioxidant that helps prevent cell damage caused by free radicals (highly reactive chemicals). Ascorbate is being studied in the prevention and treatment of some types of cancer. Azacitidine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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. Giving ascorbate with azacitidine and venetoclax may be safe, tolerable and/or effective in treating patients with newly diagnosed acute myeloid leukemia.

PRIMARY OBJECTIVE:
I. To establish the safety of high dose ascorbic acid (ascorbate) (HDA) in combination with standard of care treatment with azacitidine (aza)/venetoclax (ven). (Phase I)
II. To estimate the composite complete remission rate. (Expansion)
SECONDARY OBJECTIVES:
I. To evaluate the pre- to post-treatment change in the global deoxyribonucleic acid (DNA) methylation status.
II. To estimate the pre- to post-treatment change in the 5 methylcytosine (5mC)/5-hydroxymethlycytosine (5hMC) ratio.
III. To estimate the pre- to post-treatment change in the epigenetic mutation burden.
IV. To estimate the pre- to post-treatment change in the immune profile.
V. To estimate the day 21 marrow aplasia rate.
VI. To estimate the overall response rate (ORR).
VII. To estimate event-free survival (EFS).
OUTLINE: This is a dose-escalation study of ascorbate in combination with azacitidine and venetoclax followed by a dose-expansion study. Patients in phase I are assigned to arm B, patients in the expansion phase are randomized to 1 of 2 arms.
ARM A: Patients receive azacitidine subcutaneously (SC) on days 1-7 of each cycle and venetoclax orally (PO) on days 1-21 of cycle 1 and days 1-7 to 28 per the degree of remission/toxicity from prior cycle. Cycles repeat every 28-42 days, depending upon hematological recovery, for 3 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo chest x-ray and multigated acquisition (MUGA) scan or echocardiography scan during screening and bone marrow biopsy and aspirate, blood and urine sample collection throughout the study.
ARM B: Patients receive azacitidine SC and ascorbate intravenously (IV) on days 1-7 of each cycle and venetoclax PO on days 1-21 of cycle 1 and days 1-7 to 28 per the degree of remission/toxicity from prior cycle. Cycles repeat every 28-42 days, depending upon hematological recovery, for 3 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo chest x-ray and MUGA scan or echocardiography scan during screening and bone marrow biopsy and aspirate, blood and urine sample collection throughout the study.
After completion of study treatment, patients are followed up every 4-6 weeks for 1 year then every 1-2 months for up to 2 years from the start of treatment.
