Официальное название

A Randomized Phase II Study of Venetoclax and HMA-Based Therapies for the Treatment of Older and Unfit Adults With Newly Diagnosed FLT3-Mutated Acute Myeloid Leukemia (AML): A MyeloMATCH Substudy

Обзор

This phase II MyeloMATCH treatment trial compares the usual treatment of azacitidine and venetoclax to the combination treatment of azacitidine, venetoclax and gilteritinib in treating older and unfit patients with acute myeloid leukemia and FLT3 mutations. Azacitidine is a drug that is absorbed into DNA and leads to the activation of cancer suppressor genes, which are genes that help control cell growth. 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. Gilteritinib is in a class of medications called kinase inhibitors. It works by blocking the action of a certain naturally occurring substance that may be needed to help cancer cells multiply. This study may help doctors find out if these different approaches are better than the usual approaches. To decide if they are better, the study doctors are looking to see if the study drugs lead to a higher percentage of patients achieving a deeper remission compared to the usual approach.

Подробное описание

PRIMARY OBJECTIVE:

I. To compare the achievement rate of measured residual disease negative (MRDneg) complete remission (CR) of either triplet regimen to azacitidine and venetoclax alone within 4 cycles of therapy.

SECONDARY OBJECTIVES:

I. To compare the achievement rate of MRDneg CR/complete remission with incomplete count recovery (CRi)/complete remission with partial hematologic recovery (CRh) of either triplet regimen to azacitidine and venetoclax alone within 4 cycles of therapy.

II. To determine the safety and tolerability of the combination of gilteritinib, azacitidine, and venetoclax, if both of the triplet regimens show superiority to the azacitidine plus venetoclax regimen.

III. To determine the optimal sequence and duration of gilteritinib, when added to azacitidine and venetoclax if both of the triplet regimens show superiority to the azacitidine plus venetoclax regimen.

IV. To estimate the rates of complete remission (CR), complete remission with incomplete count recovery (CRi), and complete remission with partial hematologic recovery (CRh), morphologic leukemia-free state (MLFS), event-free survival (EFS), and overall survival (OS) of the combination of gilteritinib, azacitidine, and venetoclax versus azacitidine and venetoclax alone.

EXPLORATORY OBJECTIVES:

I. To establish the degree of reduction in FLT3- internal tandem duplication (ITD) mutation burden after 2 and 4 cycles of therapy using a highly sensitive next-generation sequencing (NGS) MRD assay and compare the median reduction in the investigational regimens among patients with CR/CRi/CRh to that of control regimen.

II. To determine if the degree of FLT3 ITD reduction is associated with the duration of remission.

III. To monitor which leukemia-associated mutations are present at the time of relapse.

IV. To monitor which co-mutations at presentation are associated with lack of response to these regimens.

V. To determine if the FLT3 variant allele frequency (VAF) at study enrollment is associated with response to the regimens.

OUTLINE: Patients are randomized to 1 of 3 regimens.

REGIMEN 1:

INDUCTION: Patients receive azacitidine intravenously (IV) or subcutaneously (SC) on days 1-7 of each cycle and venetoclax orally (PO) on days 1-28 of each cycle. Treatment repeats every 28 days for up to 2 cycles or until bone marrow assessment shows at least an MLFS response or better ("better" defined as CR, CRi, CRh), in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION: Patients receive azacitidine IV or SC on days 1-7 and venetoclax PO on days 1-28 of each cycle. Cycles repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

REGIMEN 2:

INDUCTION: Patients receive azacitidine IV or SC on days 1-7 and venetoclax and gilteritinib PO on days 1-28 of each cycle. Treatment repeats every 28 days for up to 2 cycles or until bone marrow assessment shows at least an MLFS response or better ("better" defined as CR, CRi, CRh), in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION: Patients receive azacitidine IV or SC on days 1-5, venetoclax PO on days 1-7 and gilteritinib PO on days 1-28 of each cycle. Cycles repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

REGIMEN 3:

INDUCTION: Patients receive azacitidine IV or SC on days 1-7 and venetoclax PO on days 1-28, and gilteritinib PO on days 8-21 of each cycle. Treatment repeats every 28 days for up to 2 cycles or until bone marrow assessment shows at least an MLFS response or better ("better" defined as CR, CRi, CRh), in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION: Patients receive azacitidine IV or SC on days 1-5, venetoclax PO on days 1-14 and gilteritinib PO on days 8-21 of each cycle. Cycles repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

All patients undergo bone marrow biopsy and aspiration as well as blood sample collection on the trial.

After completion of study treatment, patients are followed up every 3 months if patient is \< 2 years from randomization, every 6 months if patient is 2-5 years from randomization, and every year if patient is 5-10 years from randomization. All patients, including those who discontinue protocol therapy early, are followed for response until progression, even if non-protocol therapy is initiated, and for survival for 10 years from the date of randomization.

Критерии участия

Критерии включения

Patient must be ≥ 60 years of age or adults ˂ 60 who in the opinion of the treating physician are better served by azanucleoside-based therapy rather than intensive, cytarabine-based induction based on clinical status (i.e., performance status), organ dysfunction, or disease biology

Either measured or estimated by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) Creatinine Equation (2021)
Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months of randomization are eligible for this trial
Patients who meet the criteria below must have had an electrocardiogram (ECG) performed with a corrected QT interval using Fridericia's correction (QTcF) interval within normal limits:

Patient < 75 years old with a history of cardiac arrythmia, atrial fibrillation, or irregular QTcF interval OR

Any patient ≥ 75 years old OR
Any patient at risk for electrolyte abnormalities, including tumor lysis syndrome

Normal limits are QTcF ≤ 450 ms for males and QTcF ≤ 460 ms for females. Corrected QT interval method (QTcF) may follow institutional standards
NOTE: Since older patients and patients with cardiac disease are at risk for prolonged QTcF and many will require supportive care with agents that affect the QTcF, an ECG is recommended if clinically indicated as noted above. If the QTcF is prolonged (> 450 ms for males and > 460 ms for females), they should be treated on the Tier Advancement Pathway (TAP) instead of MM1OA-EA02. In patients where ECG is not clinically indicated, QTcF does not need to be documented

Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2 or better
