Conditions

Acute Myeloid Leukemia (AML), Acute Myeloid Leukemia Arising From Previous Myelodysplastic Syndrome, Acute Myeloid Leukemia With Multilineage Dysplasia, Myeloid Sarcoma, Secondary Acute Myeloid Leukemia, Therapy-Related Acute Myeloid Leukemia, Therapy-Related Myelodysplastic Syndrome

Brief summary

This phase II trial studies how well vosaroxin and cytarabine work in treating patients with untreated acute myeloid leukemia. Drugs used in chemotherapy, such as vosaroxin and 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.

Detailed description

PRIMARY OBJECTIVES: I. To assess the rate of complete remission (CR) after induction therapy with the combination of 7+V (vosaroxin and standard dose infusional cytosine arabinoside \[ara-C\]) for patients with newly diagnosed, previously untreated acute myelogenous leukemia (AML). SECONDARY OBJECTIVES: I. Frequency of grade 3-5 adverse events related to administration of 7+V. II. To evaluate for the presence of minimal residual disease (MRD) remaining after 7+V induction and/or re-induction. III. To determine the CR/CR with incomplete blood count recovery (CRi) rate after one and/or 2 cycles of 7+V induction. IV. To determine the time to neutrophil and platelet recovery following 7+V induction. V. To assess disease-free survival (DFS) at 1 year (yr) of patients achieving CR/CRi after 7+V induction. VI. To assess overall survival (OS) at 1 yr of all patients receiving protocol-defined therapy. VII. To determine the correlation of hematopoietic stem cell transplant (HSCT) comorbidity index and Wheatley Index scores with disease response, DFS and OS. TERTIARY OBJECTIVES: * I. To describe the mutational burden of this cohort of AML patients. * II. To correlate genomic aberration with response rate, DFS, and OS. * III. To determine the number of patients treated with vosaroxin who eventually go to allogeneic HSCT. OUTLINE: Patients receive vosaroxin intravenously (IV) on days 1 and 4 and cytarabine IV continuously on days 1-7 (Induction-I). Patients with residual leukemia and for whom a second course is indicated in the judgment of the investigator may undergo a second course of treatment (Induction-II) 14-57 days after day 1 of Induction-1 After completion of study treatment, patients are followed every 3 months for 1 year.

Minimal Residual Disease

Frequency of minimal residual disease (MRD) remaining after 7+V induction and/or re-induction

Time frame: Up to 3 months

Population: When this study was designed, it was anticipated that the data needed to calculate MRD was going to be available from standard of care. However, this ended up not being the case. MRD requires NGS testing and the study did not have budget to cover this testing. Since the NGS was not part of the standard of care for these patients, these data were not available to collect as part of the study. There is no intention to go back and report data for this Outcome Measure if funding became available.
