This phase I trial studies the side effects and best dose of a three drugs combination: CalpegA (calaspargase pegol-mknl), high dose cytarabine, and idarubicin in patients with newly diagnosed acute myeloid leukemia (AML) by measuring side effects and rate of recovery, overall survival, and symptoms experienced. Cytarabine and idarubicin are Food and Drug Administration (FDA) approved drugs. The side effects of cytarabine may include a decrease in red and white blood cells as well as platelets, greatly decreased or no production of blood cells in the bone barrow, and personality changes. The side effects of idarubicin may include infection, decreased red and white blood cells, and decreased neutrophils and platelets. The FDA has allowed us to use CalpegA as an experimental medication in patients with newly diagnosed acute myeloid leukemia. The side effects of CalpegA may include bleeding, blood clots, and inflammation of the pancreas, liver damage, and allergic reaction. Giving CalpegA, cytarabine, and idarubicin patients with newly diagnosed AML may help keep the AML from getting worse.

PRIMARY OBJECTIVES:
I. To characterize the regimen limiting toxicity (RLT) of high-dose cytarabine, idarubicin hydrochloride (idarubicin), and calaspargase pegol-mknl (CalpegA) (HAI-CalpegA) regimen as remission induction chemotherapy in patients with newly diagnosed AML.
II. Identifying the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of HAI-CalpegA.
SECONDARY OBJECTIVES:
I. To evaluate complete remission (CR) to HAI-CalpegA in patients with newly diagnosed AML.
II. To evaluate the composite response rate (CR/complete remission with partial hematologic recovery [CRh]/complete remission with incomplete hematological recovery [CRi]) to HAI-CalpegA in patients with newly diagnosed AML.
III. To assess the event-free survival (EFS), defined as time on study to induction failure, relapse or death of patients with newly diagnosed AML receiving HAI-CalpegA and subsequent consolidations.
IV. To estimate the overall survival (OS) of patients with newly diagnosed AML receiving HAI-CalpegA and subsequent consolidations.
V. To estimate the proportion of patients with newly diagnosed AML who will be eligible for allogeneic hematopoietic stem cell transplantation (allo-HSCT) after receiving HAI-CalpegA.
VI. To measure measurable (minimal) residual disease in patients with AML who receive HAI-CalpegA after the induction therapy.
VII. To describe the frequency and severity of treatment-emergent adverse events (TEAEs) in patients treated on this study with HAI-CalpegA.
VIII. To describe the association between pretreatment disease and patient characteristics with outcomes.
IX. To characterize the pharmacokinetics (PK) (plasma asparaginase activity) of CalpegA in patients with AML who receive HAI-CalpegA therapy.
X. To characterize the pharmacodynamic (PD) (plasma amino acid levels including asparagine and glutamine) of CalpegA in patients with AML who receive HAI-CalpegA therapy.
OUTLINE: This is a dose-escalation study of CalpegA.
INDUCTION: Patients receive high-dose cytarabine (HiDAC) intravenously (IV) every 12 hours on days 1, 3, 5, and 6, and idarubicin IV after the 1st, 3rd, and 5th HiDAC doses. Patients also receive CalpegA IV 6 hours after the 6th dose of HiDAC. Patients achieving CR, CRh, or CRi proceed to Consolidation.
CONSOLIDATION: Patients receive HiDAC IV over 3 hours twice daily (BID) on days 1, 3, and 5. Patients also receive CalpegA IV 6 hours after the 6th dose of HiDAC. Treatment repeats every 4-8 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity.
After completion of the study treatment, patients are followed for 30 days.
