Testing the Use of Combination Therapy in Patients With Persistent Low Level Acute Myeloid Leukemia Following Initial Treatment, The ERASE Study (A MyeloMATCH Treatment Trial)

Eradicating Measurable Residual Disease in Patients With Acute Myeloid Leukemia (AML) Prior to StEm Cell Transplantation (ERASE): A MyeloMATCH Treatment Trial

This phase II MyeloMATCH treatment trial compares cytarabine versus (vs.) cytarabine and venetoclax vs. liposome-encapsulated daunorubicin-cytarabine and venetoclax vs. azacitidine and venetoclax for treating patients who have residual disease after treatment for acute myeloid leukemia (AML). Cytarabine is in a class of medications called antimetabolites. It works by slowing or stopping the growth of cancer cells in the body. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Liposome-encapsulated daunorubicin-cytarabine is a drug formulation that delivers daunorubicin and cytarabine in small spheres called liposomes, which may make the drugs safer or more effective. Azacitidine is a drug that interacts with DNA and leads to the activation of tumor suppressor genes, which are genes that help control cell growth. This study may help the study doctors find out if the different drug combinations are equally effective to the usual approach of cytarabine alone while requiring a shorter duration of treatment. To decide if they are better, the study doctors will be looking to see if the study drugs lead to a higher percentage of patients achieving a deeper remission compared to cytarabine alone.

PRIMARY OBJECTIVES:

I. To improve the rate of measurable residual disease (MRD) negative complete remission (CR) in patients with acute myeloid leukemia (AML) who have achieved a MRD positive CR after induction chemotherapy received in a myeloMATCH young adult basket tier-1 protocol.

II. To determine the rate of achieving MRD negative CR after 2 cycles of post-remission therapy with cytarabine vs. cytarabine + venetoclax or liposome-encapsulated daunorubicin-cytarabine (daunorubicin and cytarabine liposome) + venetoclax azacitidine + venetoclax in AML or myelodysplastic syndrome (MDS) who were MRD positive post induction therapy.

SECONDARY OBJECTIVES:

I. To determine the disease-free survival, overall survival in this group of patients.

II. Assess the percentage of patients who receive allogeneic hematopoietic stem cell transplantation (HCT).

III. Compare toxicities of each experimental arm with the control arm.

EXPLORATORY OBJECTIVES:

I. Evaluate MRD kinetics by following patients with detectable MRD through tier 2 and beyond.

II. Evaluate longer term outcomes by treatment arm, genomics, MRD outcome, and other features as patients receive additional myeloMATCH therapies to generate testable hypotheses for more precise patient selection for these therapies aimed at improving outcomes.

OUTLINE: Patients are randomized to 1 of 4 arms.

ARM A: Patients receive cytarabine intravenously (IV) on study. Patients undergo bone marrow aspiration and biopsy on study. Patients may also undergo echocardiogram (ECHO) and/or multigated acquisition scan (MUGA) as clinically indicated.

ARM B: Patients receive cytarabine IV and venetoclax orally (PO) on study. Patients undergo bone marrow aspiration and biopsy on study. Patients may also undergo ECHO and/or MUGA as clinically indicated.

ARM C: Patients receive liposome-encapsulated daunorubicin-cytarabine IV and venetoclax PO on study. Patients undergo bone marrow aspiration and biopsy on study. Patients may also undergo ECHO and/or MUGA as clinically indicated.

ARM D: Patients receive azacitidine IV or subcutaneously (SC) and venetoclax PO on study. Patients undergo bone marrow aspiration and biopsy on study. Patients may also undergo ECHO and/or MUGA as clinically indicated.

MRD is defined as > 0.1% flow cytometry on bone marrow (BM) biopsy as assessed by MDNet. The definition of CR or CRh may be made +/- 2 weeks from BM biopsy

Exclusion Criteria:

• Patient must not be pregnant or breast-feeding due to the potential harm to an unborn fetus and possible risk for adverse events in nursing infants with the treatment regimens being used.
