Testing the Addition of Venetoclax or Gemtuzumab Ozogamicin (GO) to Usual Treatment Regimen (Cytarabine and Daunorubicin, "7+3") for Core Binding Factor Acute Myeloid Leukemia (CBF-AML) to Improve Response (A MyeloMATCH Treatment Trial)

About
This phase II MyeloMATCH treatment trial compares the effect of venetoclax to gemtuzumab ozogamicin, when given with cytarabine and daunorubicin ("7+3" regimen), for the treatment of patients with core binding factor acute myeloid leukemia (CBF-AML). 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. Gemtuzumab ozogamicin is a monoclonal antibody, called gemtuzumab, linked to an antitumor antibiotic drug, called ozogamicin. Gemtuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD33 receptors, and delivers ozogamicin to kill them. Chemotherapy drugs, such as cytarabine and daunorubicin work in different ways to stop the growth of cancer cells either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax with cytarabine and daunorubicin may have fewer side effects and be as effective or better than the combination with gemtuzumab ozogamicin in treating patients with core binding factor AML.
Full description
PRIMARY OBJECTIVE:
I. Compare the rates of complete remission (CR) without measurable residual disease (CRMRD-) by multiparameter flow cytometry following induction therapy between the two treatment arms in each cohort separately.
SECONDARY OBJECTIVES:
I. To compare the rates of CR and composite complete remission (CRc) (CR+complete remission with incomplete hematologic recovery [CRi]+complete remission with partial hematologic recovery [CRh]) between the treatment arms.
II. To compare the overall survival (OS) between the treatment arms. III. To compare the event-free survival (EFS). IV. To compare cumulative incidence of relapse (CIR). V. To compare cumulative incidence of death (CID) between the treatment arms. VI. To compare the rate of early death at 30 days and 60 days between the treatment arms.
VII. To assess the rate and frequency of adverse events between treatment arms. VIII. To evaluate mutant RAS and mutant KIT as predictive biomarkers for CRMRD- rate in CBF AML.
EXPLORATORY OBJECTIVE:
I. To compare MRD (and its clinical implication, e.g., relapse rates) between flow cytometry (FC) and next generation sequencing (NGS)-based (RUNX1::RUNX1T1 or CBFB::MYH11).
CORRELATIVE OBJECTIVES:
I. To evaluate the frequency and clinical impact of variant allele frequency (VAF) of KIT mutation, KIT mutations in different exons (e.g., exon 8 or 17), CD33 expression, additional (secondary) mutations and cytogenetic abnormalities.
II. To evaluate the differences in clinical and molecular outcomes in patients with RUNX1::RUNX1T1 mutated versus CBFB::MYH11 mutated CBF AML.
OUTLINE: Patients are randomized to 1 of 2 regimens.
REGIMEN 1: Patients receive gemtuzumab ozogamicin intravenously (IV) on days 1 and 4, cytarabine IV, continuously, on days 1-7 and daunorubicin IV on days 1-3 in the absence of disease progression or unacceptable toxicity. Patients then undergo standard of care consolidation/post-remission treatment at the discretion of the treating physician. Patients undergo echocardiography or multigated acquisition (MUGA) scan during screening and bone marrow aspiration and biopsy and blood sample collection throughout the study. Patients may also undergo optional buccal swab collection throughout the study.
REGIMEN 2: Patients receive venetoclax orally (PO) once daily (QD) on days 1-11, cytarabine IV, continuously, on days 2-8 and daunorubicin IV on days 2-4 in the absence of disease progression or unacceptable toxicity. Patients then undergo standard of care consolidation/post-remission treatment at the discretion of the treating physician. Patients undergo echocardiography or MUGA scan during screening and bone marrow aspiration and biopsy and blood sample collection throughout the study. Patients may also undergo optional buccal swab collection throughout the study.
After completion of study treatment, patients are followed up at relapse and every 3 months for 2 years, then every 6 months until 5 years.

Inclusion and exclusion criteria
Inclusion Criteria:
-
GENERAL MYELOMATCH CRITERIA: Patients must be registered to the Master Screening and Reassessment Protocol and assigned to this protocol by the MATCHBox Treatment Verification Team
-
GENERAL MYELOMATCH CRITERIA: Participants must not have received prior anti-cancer therapy for AML or myelodysplastic syndrome (MDS)
- Note: Hydroxyurea to control the white blood cell count (WBC) and cytarabine up to 1 g/m^2 for urgent cytoreduction is allowed.
- Note: Prior erythroid stimulating agent (ESA) is not considered prior therapy for the purposes of eligibility
-
GENERAL MYELOMATCH CRITERIA: Participants must not receive any cytarabine-containing therapy other than up to 1 g/m^2 of cytarabine, which is allowed for urgent cytoreduction. The use of prior hydroxyurea, all-trans retinoic acid (ATRA), BCR-ABL directed tyrosine kinase inhibitor, erythropoiesis-stimulating agent, thrombopoietin receptor agonist and lenalidomide is allowed
-
Diagnosis of AML with t(8;21)(q22;q22.1)/RUNX1::RUNX1T1 or AML with inv(16)(p13.1q22) or t(16;16)(p13.1;q22)/CBFB::MYH11. No FLT3 mutation (these patients should be considered for a FLT3-focused Myelomatch study)
-
No prior AML or MDS-directed therapy except for urgent treatment of leukocytosis with leukapheresis, cytarabine, and hydroxyurea, Prior intrathecal chemotherapy for central nervous system (CNS) involvement of AML is permitted
-
Age 18-59 years
-
Eastern Cooperative Oncology Group (ECOG) performance status ≤ 3
-
Total bilirubin ≤ 1.5 x upper limit of normal (ULN) (unless patient has a history of Gilbert syndrome and direct bilirubin is ≤ 1.5 x ULN)
-
Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase [SGOT])/ alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) ≤ 3 x upper limit of normal (ULN)
-
Glomerular filtration rate (GFR) ≥ 30 mL/min/1.73m^2
-
Not pregnant and not nursing, because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown. Therefore, for women of childbearing potential only, a negative urine or serum pregnancy test done ≤ 7 days prior to registration is required
-
Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
-
Participants with CNS disease are eligible for this trial and will be treated according to institutional guidelines with intrathecal chemotherapy for this aspect of their disease
-

-
For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
-
Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
-
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.
