NCT ID: NCT04526288

Last Updated: 2024-05-23

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE2
• Total Enrollment: 1 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-08-09

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.

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 will be followed for up to 2 years.

Eligibility Criteria

Inclusion Criteria

• 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
