ClinConnect Summary

This clinical trial is looking at the best level of chemotherapy treatment for adults who have a type of blood cancer called acute myeloid leukemia (AML) or related conditions, but who may not be strong enough to handle the usual intensive treatments. Traditionally, doctors have given either strong, aggressive chemotherapy to healthier patients or gentler, less intense treatment to those considered less fit, often because of age or other health issues. This study will see if patients are willing to be randomly assigned—like letting a computer pick—to receive either higher- or lower-intensity chemotherapy. The goal is to find out which approach works best and is safest for patients who might be at higher risk of side effects.

Adults 18 years and older with a diagnosis of AML or similar blood cancers, who have certain health conditions or limitations making them less fit for very intensive therapy, might be eligible. For example, patients with heart or lung problems, moderate kidney or liver issues, or those who have some difficulty with daily activities could take part. Participants will be carefully evaluated to ensure their heart and overall health are stable enough for treatment. If they join the trial, they will receive either a stronger or gentler chemotherapy plan, chosen at random, and their doctors will closely monitor their response and side effects. This study is important because it could help doctors better tailor treatment to each patient’s health, potentially improving outcomes and quality of life.

Eligibility criteria

• Inclusion Criteria:
• • Age ≥ 18 years
• • Diagnosis of high grade myeloid neoplasm (\> 10% blasts in blood or marrow), other than acute promyelocytic leukemia (APL) according to the 2022 International Consensus Classification (ICC) classification. Patients with acute leukemias of ambiguous lineage are eligible
• • The use of cytoreductive therapy before treatment is permitted. Patients with symptoms/signs of leukostasis, white blood cell (WBC) \> 100,000/μL, or acute symptoms that in the opinion of the treating physician are likely related to their high-grade myeloid neoplasm may receive up to 2 doses of cytarabine (up to 500 mg/m\^2 each) prior to study day 1
• • Patients may have received treatment for antecedent low-grade myeloid neoplasm (\< 10% myeloid blasts on blood or bone marrow)
• • Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 3 (for patients aged \< 75 years) or ECOG performance status of 0 - 2 (for patients aged ≥ 75 years)
• * The presence of one or more of the following criteria for 'unfitness'. (Patients without respiratory symptoms at rest are eligible and should only complete spirometry/diffusion capacity of the lung for carbon monoxide \[DLCO\] measurements as clinically indicated):
• • ECOG Performance Status of 2 or 3
• • Cardiac history of congestive heart failure (CHF) requiring treatment or ejection fraction ≤ 50% or chronic stable angina
• • Documented DLCO ≤ 65% or forced expiratory volume in 1 second (FEV1) ≤ 65%; or dyspnea at rest, or requiring supplemental oxygen
• • Creatinine clearance ≥ 30 mL/min to \< 45 ml/min
• • Moderate hepatic impairment with total bilirubin \> 1.5 to ≤ 3.0 × upper limit of normal (ULN)
• • Any other comorbidity that the physician judges to be incompatible with intensive chemotherapy
• * Adequate cardiac function:
• * Patients aged ≤ 60 years without a history of cardiac disease or evidence of heart failure are eligible if they also exhibit the following:
• • Chest x-ray (CXR) without evidence of moderate or severe pulmonary edema or pleural effusion, and a normal cardio-mediastinal silhouette
• • Electrocardiogram (ECG) without evidence of atrial or ventricular chamber enlargement
• • Note that patients with either abnormal CXR or ECG should have a structural heart assessment (echocardiogram, multigated acquisition scan \[MUGA\] or similar) and are eligible if left ventricular ejection fraction (LVEF) \> 40% and the abnormalities in the CXR/ECG do not preclude safe administration of intensive chemotherapy
• • Patients with a documented left ventricular ejection fraction (LVEF) ≥ 40%, assessed within 3 months prior to registration, e.g. by MUGA scan or echocardiography, or another appropriate diagnostic modality are eligible
• • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3x ULN, unless judged due to leukemic organ involvement
• • Total bilirubin ≤ 3 x ULN unless judged due to leukemic organ involvement, Gilbert's syndrome, or hemolysis
• • Women of childbearing potential and men must agree to use adequate contraception beginning at the signing of the consent until at least 4 weeks after the last dose of study drug
• • HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
• • Ability to understand and the willingness to sign a written informed consent document
• Exclusion Criteria:
• • Known hypersensitivity to cytarabine, anthracycline, hypomethylating agents, or venetoclax
• • Cardiovascular disability status of New York Heart Association class ≥ 2. Class 2 is defined as cardiac disease in which patients are comfortable at rest but ordinary physical activity results in fatigue, palpitations, dyspnea, or anginal pain
• • Subject exhibits evidence of other clinically significant uncontrolled systemic infection requiring therapy (viral, bacterial or fungal)
• • Concomitant illness associated with a likely survival of \< 1 year
• • Active pregnancy or breast feeding
