Venetoclax, Cladribine, Low Dose Cytarabine, and Azacitidine in Treating Patients With Previously Untreated Acute Myeloid Leukemia

This phase II trial studies how well venetoclax, cladribine, low dose cytarabine, and azacitidine work in treating patients with acute myeloid leukemia that has previously not been treated. Drugs used in chemotherapy, such as venetoclax, cladribine, and low dose cytarabine, 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. Azacitidine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving venetoclax, cladribine, low dose cytarabine induction followed by cladribine, low dose cytarabine, and azacitidine consolidation may work better in treating patients with acute myeloid leukemia.

Inclusion Criteria: 1. Participants with previously untreated acute myeloid leukemia (AML). Prior therapy with hydroxyurea, hematopoietic growth factors, HMA, ATRA, or a total dose of cytarabine up to 2g (for emergency use for stabilization) is allowed. 2. Age \>/= 50 years. Participants aged \< 50 years who are unsuitable for standard induction therapy may be eligible after discussion with primary investigator 3. Adequate organ function as defined below: * liver function (bilirubin \< 2mg/dL, AST and/or ALT \
