Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Myelodysplastic Syndrome With Excess Blasts-2 Myeloid Neoplasm Procedure: Allogeneic Hematopoietic Stem Cell Transplantation Drug: Liposome-encapsulated Daunorubicin-Cytarabine Phase 2

Detailed Description:

OUTLINE:

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.

Primary Outcome Measures :
  1. Overall survival [ Time Frame: Up to 5 years post-randomization ]
    The survival (in days) of subjects in the two arms will be compared using the log-rank test.


Secondary Outcome Measures :
  1. Relapse-free survival [ Time Frame: From the time of randomization and (among patients transplanted) from the time of transplantation up to 5 years post-randomization ]
    The following comparisons will be made: (1) number of days elapsing between the date of MRD identification and the date of death or relapse, (2) among transplanted patients, the number of days elapsing between the date of transplantation and the date of death or relapse.

  2. Rate of transplantation [ Time Frame: Up to 5 years post-randomization ]
    The proportion of patients having begun transplantation conditioning 60 days and 180 days following enrollment will be compared using the chi-squared test. The time to transplantation among the two arms will be compared by comparing the number of days elapsed between enrollment and the initiation of transplantation conditions by the log-rank test.

  3. Frequencies of the types of transplantation received [ Time Frame: Up to 5 years post-randomization ]
    Among the patients receiving transplantation, the proportion of patients in each arm receiving myeloablative transplantation conditioning will be compared using the chi-squared or Fisher's exact test. Among patients receiving transplantation, the proportion of patients in each arm receiving donor stem cells from a haploidentical donor, an unrelated donor, or from cord blood unit will each be compared using the chi-squared or Fisher's exact test.
