Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• A potential participant must have met all the following criteria to be eligible to participate in the study:
• Had newly-diagnosed, previously untreated acute myeloid leukemia (AML) (according to the World Health Organization criteria) with at least 20% blasts in the peripheral blood or bone marrow.
• Was aged ≥18 years.
• Adverse genetic risk (according to European LeukemiaNet [ELN] criteria), defined as nay of the following genetic abnormalities:
• t(6;9)(p23;q34.1); DEK-NUP214
• - t(v;11q23.3); KMT2A rearranged
• - t(9;22)(q34.1;q11.2); BCR-ABL1
• - inv(3)(q21.3q26.2) or t(3;3)(q21.3;q26.2); GATA2, MECOM(EVI1)
• - -5 or del(5q); -7; -17/abn(17p)
• - Complex karyotype, monosomal karyotype
• - Wild-type NPM1 and FLT3-ITDhigh
• - Mutated RUNX1, mutated ASXL1, or mutated TP53 OR
• Intermediate genetic risk (according to ELN criteria), defined as any of the following genetic abnormalities:
• Mutated NPM1 and FLT3-ITDhigh
• - Wild-type NPM1 without FLT3-ITD or with FLT3-ITDlow (without adverse-risk genetic lesions)
• - t(9;11)(p21.3;q23.3); MLLT3-KMT2A
• - Cytogenetic abnormalities not classified as favorable or adverse
• Had an Eastern Cooperative Oncology Group performance status of 0 to 2.
• Provided written informed consent to participate in the study.

You may not qualify if…

• A potential participant who met any of the follow criteria was not eligible to participate in the study:
• Leukemia exclusions:
• Had acute promyelocytic leukemia (t(15;17)), myeloid sarcoma without bone marrow involvement, or blast transformation of chronic myelogenous leukemia.
• Not applicable (criterion removed in Amendment 1 of the Clinical Study Protocol).
• Not applicable (criterion removed in Amendment 1 of the Clinical Study Protocol).
• Had clinical evidence of central nervous system leukemia.
• Prior/Concomitant Therapy:
• Had previously received AML treatment, including Vyxeos (CPX-351, liposomal cytarabine and daunorubicin), gemtuzumab ozogamicin, or any other prohibited concomitant AML therapy previously received or anticipated to start during the study.
• Note: Prior hydroxyurea and emergency leukapheresis to control white blood cell count were allowed. All-trans retinoic acid during workup and a single dose of intrathecal cytarabine and/or methotrexate was permitted for participants who were undergoing lumbar puncture to evaluate central nervous system involvement.
• Were receiving any form of anticoagulant therapy (e.g., unfractionated heparin, low molecular weight heparin, coumadin, factor Xa inhibitors).
• Note: Heparin flush of indwelling catheters was permitted.
• Received treatment with any other investigational agent within 28 days or 5 half-lives, whichever was longer, prior to baseline.
• Underwent any major surgery or radiation therapy within 28 days prior to baseline.
• Medical conditions:
• Had immediately life threatening, severe complications of leukemia such as pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation.
• Had active or uncontrolled bleeding at the time of randomization; a bleeding disorder, either inherited or caused by disease; a history of known arterial-venous malformation, intracranial hemorrhage, or suspected or known cerebral aneurysm; or clinically significant (in the judgement of the Investigator) gastrointestinal bleeding within 3 weeks prior to randomization.
• Had the presence of significant active or uncontrolled infection, including human immunodeficiency virus (HIV) or hepatitis B or C.
• Note: Subjects with an infection who were receiving treatment (antibiotic, antifungal, or antiviral treatment) may have entered into the study but must have been afebrile and hemodynamically stable for ≥72 hours. Patients who had current evidence of invasive fungal infection (positive blood or tissue culture) must have had subsequent negative cultures to be eligible.
• Had active (uncontrolled, metastatic) second malignancy. Note: A second malignancy that was in remission was permitted if there was clinical evidence of disease stability for a period of greater than 6 months off cytotoxic chemotherapy that was documented by imaging, tumor marker studies, etc. Long-term nonchemotherapy treatment (e.g., hormonal therapy) was acceptable.
• Had psychiatric or neurological conditions that could have compromised participant safety or compliance.
• Had a history of severe congestive heart failure or other cardiac disease that contraindicated the use of idarubicin or daunorubicin (e.g., cardiac ejection fraction <45%, as determined by echocardiography or multigated acquisition scan).
• Diagnostic assessments:
• Had a corrected QT interval >480 msec.
• Had severe renal impairment, as determined by calculated creatinine clearance <30 mL/min or estimated glomerular filtration rate <30 mL/min/1.73 m2.
• Had alanine aminotransferase or aspartate aminotransferase >3x the upper limit of normal (ULN) or total bilirubin >2x the ULN.
