简要总结
This phase I trial tests the safety, side effects, and best dose of lintuzumab-Ac225 in combination with venetoclax and ASTX-727, and how well they work in treating patients with newly diagnosed acute myeloid leukemia (AML). Lintuzumab-Ac225 is a monoclonal antibody, called lintuzumab, linked to a radioactive agent called actinium Ac 225. Lintuzumab attaches to CD33 positive cancer cells in a targeted way and delivers actinium Ac 225 to kill them. 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. ASTX-727 is a combination of two drugs, cedazuridine and decitabine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Giving lintuzumab-Ac225 in combination with venetoclax and ASTX-727 may be safe and tolerable in treating patients with newly diagnosed AML and may improve the chance of going into remission and staying in remission for a longer period of time.
详细描述
PRIMARY OBJECTIVE:
I. To determine recommended phase 2 dose (RP2D) of actinium Ac 225 lintuzumab (lintuzumab-Ac225) when used in combination with venetoclax and decitabine and cedazuridine (ASTX-727).
SECONDARY OBJECTIVES:
I. To determine the maximum tolerated dose of lintuzumab-Ac225 when used in combination with venetoclax and ASTX-727.
II. To describe the frequency and severity of adverse events of patients treated on study, including cytopenia and organ toxicity after second dose of lintuzumab-Ac225.

- •Patients must be considered ineligible for induction therapy defined by the following
- •≥ 75 years of age; OR
- •<75 years of age with at least one of the following co-morbidities or high-risk genetic features. Geriatric assessment and other tools to assess frailty have not been validated in patients with AML, and therefore will not be used to assess eligibility
- •Eastern Cooperative Oncology Group (ECOG) Performance Status of 2 or 3;
- •Cardiac history of congestive heart failure (CHF) requiring treatment or Ejection Fraction ≤ 50% or chronic stable angina;
- •Diffusion capacity of lung for carbon monoxide (DLCO) ≤ 65% or forced expiratory volume in 1 second (FEV1) ≤ 65%;

- •Complex karyotype or monosomal karyotype as defined by ELN 2022
- •Mutated TP53
- •Age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of linituzumab-Ac-225 in combination with venetoclax and ASTX-727 in patients < 18 years of age, children are excluded from this study
- •ECOG performance status 0-3 (Karnofsky ≥ 60%). For patients with ECOG performance status of 3, the decline in status should be due to AML per investigator's determination
- •Total bilirubin ≤ 3.0x institutional ULN unless considered due to Gilbert syndrome
- •Aspartate aminotransferase (AST)(serum gluatmic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT)(serum glutamic pyruvic transaminase [SGPT]) ≤ 3 x institutional ULN
- •Creatinine clearance ≥ 60 ml/min

- •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 (NYHA) Functional Classification. Patients with heart failure must have NYHA functional class congestive heart failure (CHF) II or below to be eligible
- •Hydroxyurea, cytarabine or leukopheresis are allowed for management of hyperleukocytosis, before initiation of study therapy. All-trans retinoic acid (ATRA) given emergently for suspected acute promyelocytic leukemia (APL) is also allowed. White blood cell (WBC) count must be < 25 x 10^9/L to start on study therapy per venetoclax label. Hydroxyurea and ATRA may be administered up to one day prior to start of study treatment
- •Ability to understand and the willingness to sign a written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants
排除标准
- •Acute promyelocytic leukemia (APL)
- •Patients with favorable risk AML per the European LeukemiaNet (ELN) 2022 criteria
- •Active central nervous system (CNS) involvement of AML requiring therapy
- •Prior therapy with radiopharmaceuticals or external beam radiation therapy (EBRT)
- •Previous therapy with venetoclax or other BCL-2 directed therapy
