Comparing Cytarabine + Daunorubicin Therapy Versus Cytarabine + Daunorubicin + Venetoclax Versus Venetoclax + Azacitidine in Younger Patients With Intermediate Risk AML (A MyeloMATCH Treatment Trial)

Официальное название

A Measurable Residual Disease (MRD) Focused, Phase II Study of Venetoclax Plus Chemotherapy for Newly Diagnosed Younger Patients With Intermediate Risk Acute Myeloid Leukemia: A Tier 1 MYELOMATCH SubStudy

Обзор

This phase II MyeloMATCH treatment trial compares cytarabine with daunorubicin versus cytarabine with daunorubicin and venetoclax versus venetoclax with azacitidine for the treatment of younger patients with intermediate risk acute myeloid leukemia (AML). Cytarabine is a drug that inhibits some of the enzymes needed for deoxyribonucleic acid (DNA) replication and repair and can slow or stop the growth of cancer cells. Daunorubicin is a drug that blocks a certain enzyme needed for cell division and DNA repair, and it may kill cancer cells. 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. Azacitidine is a drug that interacts with DNA to activate tumor-suppressing genes, resulting in an anti-tumor effect. Adding venetoclax to cytarabine and daunorubicin, and adding venetoclax to azacitidine, may work better than the usual treatment of cytarabine with daunorubicin alone. To decide if they are better, the study doctors are looking to see if venetoclax increases the rate of elimination of AML in participants by 20% or more compared to the usual approach.

Подробное описание

PRIMARY OBJECTIVE:

I. To compare the rates of undetectable measurable residual disease (MRD) in patients who achieve a complete remission (CR) after induction therapy with 7 +3 (cytarabine + daunorubicin hydrochloride \[daunorubicin\]) versus (vs.) azacitidine + venetoclax vs. 7+3 + venetoclax.

SECONDARY OBJECTIVES:

I. To estimate the frequency and severity of toxicities with each of the regimens.

II. To estimate complete remission (CR) rates (with and without MRD), complete remission with incomplete count recovery (CRi) (with and without MRD) rates, event-free survival (EFS), relapse-free survival (RFS), and overall survival (OS) with each of the regimens.

TERTIARY OBJECTIVES:

I. To evaluate response to therapy received according to genomic findings. II. To evaluate MRD kinetics by following patients with detectable MRD through Tier 2 and beyond.

III. To 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.

OUTLINE: Patients are randomized to 1 of 3 arms.

ARM I: Patients receive daunorubicin intravenously (IV) on days 2-4, cytarabine IV continuously on days 2-8, and venetoclax orally (PO) once daily (QD) on days 1-11. Cycle is 28 days and treatment is given in the absence of disease progression or unacceptable toxicity. Based on a bone marrow aspiration assessment (completed at the discretion of the treating investigator), patients may receive reinduction consisting of daunorubicin IV on days 2-3, cytarabine IV continuously on days 2-6, and venetoclax PO QD on days 1-8. Cycle is 28 days and treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspiration and collection of blood samples on study and as clinically indicated. Additionally, patients undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening.

ARM II: Patients receive azacitidine IV or subcutaneously (SC) on days 1-7 or days 1-5 and 8-9 and venetoclax PO QD on days 1-28 of each cycle. Cycles repeat every 28 days for a total of 2 cycles, in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspiration and collection of blood samples on study and as clinically indicated. Additionally, patients undergo ECHO or MUGA during screening.

ARM III: Patients receive daunorubicin IV on days 1-3 and cytarabine IV, continuously, on days 1-7. Cycle is 28 days and treatment is given in the absence of disease progression or unacceptable toxicity. Based on a bone marrow aspiration assessment (completed at the discretion of the treating investigator), patients may receive reinduction consisting of cytarabine IV, continuously, on days 1-5 and daunorubicin IV on days 1-2. Cycle is 28 days and treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspiration and collection of blood samples on study and as clinically indicated. Additionally, patients undergo ECHO or MUGA during screening.

After completion of study treatment, patients are followed up at 4 weeks, every 3 months for 1 year every 6 months for the second year and yearly thereafter.
