Brief summary
This phase 2, open label, non-randomized study will evaluate the safety of administering high dose cytarabine (HiDAC) consolidation therapy on days 1-3 of each cycle, as compared to standard administration on days 1, 3, and 5 of each cycle, in patients 61 years and older with de novo acute myeloid leukemia (AML).
Interventions
Subjects on this arm will prospectively receive consolidation therapy with cytarabine. Subjects will be treated with 1000 mg/m2 cytarabine intravenously every 12 hours on Days 1-3 of each consolidation cycle. Subjects will receive up to four consolidation cycles.

Eligibility
Inclusion criteria
* Both males and females ≥ 61 years of age * A clinical diagnosis of de novo, non-M3 acute myeloid leukemia (AML) confirmed by greater than 20% blasts in peripheral blood or on diagnostic bone marrow biopsy who have completed intensive induction chemotherapy and are confirmed in complete remission #1 (defined by \< 5% myeloblasts on recovery bone marrow biopsy, Absolute neutrophil count \> 1000/uL and platelets \> 100x103/uL) and able to receive HiDAC consolidation #1 * Patients on the prospective arm must be willing to have labs/clinic visits at UF Health Shands approximately every 48 hours +/- 24 hours after discharge from chemotherapy admission to be included. If prospective subjects cannot be followed at the UF site then telephone visits are allowed to follow for toxicity and transfusions. Records can be requested from subject's local physician office. * Written informed consent obtained from the subject and the subject agrees to comply with all the study-related procedures. For subjects on the historical arm, there will be a waiver of informed consent (as these patients may be deceased or not be available for retrospective consent).
Exclusion criteria
* Age \< 61 years * Patients unable to provide informed consent for prospective arm * Secondary AML (documented history of antecedent hematological disorder, such as myelodysplastic syndrome or therapy-related AML) or chronic myeloid leukemia (CML) in blast crisis * Patients receiving, received, or who will receive a FLT3 inhibitor * Patients receiving, received, or who will receive an IDH1 or IDH2 inhibitor * Serum creatinine greater than 2 mg/dL * History of any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of protocol therapy or that might affect the interpretation of the results of the study or that puts the subject at high risk for treatment complications, in the opinion of the treating physician * Prisoners or subjects who are involuntarily incarcerated, or subjects who are compulsorily detained for treatment of either a psychiatric or physical illness * For historical arm, subjects will be excluded if adequate data is not available in electronic medical record (e.g., if patient was followed by their local oncologist between chemotherapy cycles and labs/transfusions/clinic notes, etc. are not available) * Karnofsky performance status of 40 or less at study entry
