Acute Myeloid Leukemia Clinical Trial
CPX-351 Versus Immediate Stem Cell Transplantation for the Treatment of High-Grade Myeloid Cancers With Measurable Residual Disease
This phase II trial studies the effect of CPX-351 followed by donor stem cell transplantation versus immediate donor stem cell transplantation in treating patients with high-grade myeloid cancers with measurable residual disease. Chemotherapy drugs, such as CPX-351, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before donor stem cell transplantation may help kill cancer cells in the body and make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow.
Patients are randomized to 1 of 2 arms.
ARM A: Patients undergo alloHCT.
ARM B: Patients receive CPX-351 intravenously (IV) over 90 minutes on days 1, 3, and 5. Treatment may repeat for an additional cycle for a total of 2 cycles (on days 1 and 3 only of cycle 2) in the absence of disease progression or unacceptable toxicity. Within 60 days after completion of CPX-351, patients undergo alloHCT.
After completion of study enrollment, patients are followed up for up to 5 years.
Acute myeloid leukemia (AML) other than acute promyelocytic leukemia (APL), myelodysplastic syndrome with excess blasts-2 (MDS-EB2), or another high-risk myeloid neoplasm (>= 10% blasts in the blood or marrow), having completed at least one cycle of chemotherapy intended to induce remission
Subjects must have MRD, defined as the presence of original disease detected by multi-parameter flow cytometry and cytogenetic/molecular assessment within 90 days of chemotherapy intended to induce remission:
Abnormal cells identified by multiparameter flow cytometry, present at a frequency of between 0% and 5% of total nucleated cells, judged in the opinion of the hematopathologist to represent continued presence of malignant cells
Abnormal karyotype; present in any number of metaphase cells
Abnormal fluorescence in-situ hybridization; judged in the opinion of the hematopathologist to represent continued presence of malignant cells
The presence of any leukemia associated mutation as detected by DNA sequencing, except mutations in DNMT3A, TET2, or ASXL1.

For the purposes of this study intensive chemotherapy will include regimens listed below. Additional regimens may be included at the discretion of the study principal investigator (PI)
Any regimen including cytarabine at a dose of 100 mg/m^2/day for at least 7 days and an anthracycline at any dose +/- gemtuzumab ozogamicin (GO)
Any regimen including cytarabine at a dose of at least 100 mg/m^2/day for at least 5 days and a purine analog at any dose (e.g. clofarabine, fludarabine, cladribine) +/- GO

Additionally, subjects should be eligible in the opinion of their treating physician for allogeneic transplantation
Bilirubin =< 2.5 x institutional upper limit of normal, unless elevation is thought to be due to Gilberts syndrome or hemolysis (within 14 days of study start [unless otherwise noted] to be enrolled in the study)
Left ventricular ejection fraction >= 40% assessed by multiple gated acquisition scan (MUGA), echocardiography or other appropriate diagnostic modality within 12 months of enrollment with no clinical evidence of decompensated congestive heart failure
Creatinine clearance of >= 30 mL/min as measured by Cockcroft Gault equation (within 14 days of study start [unless otherwise noted] to be enrolled in the study)
Consent of female patients with a negative serum or urine pregnancy test to use a medically acceptable method of contraception throughout the entire study period and for 6 months following the last dose of CPX-351
Male patients must be willing to refrain from sperm donation for 6 months following the last dose of CPX-351 and must use adequate contraception throughout the entire study period and for 6 months following the last dose of CPX-351
Patients enrolling in this trial should intend to complete the treatments described and should be eligible in the opinion of the treating physician for allogeneic transplantation
Patients must have a caregiver capable of providing post-HCT care, who will be present once conditioning therapy begins
The informed consent document (ICF) must be signed and dated by the subject or by the subject's legally authorized representative if the subject is unable to sign
