Targeted Radiotherapy + Anti-Cancer Drugs for Acute Myeloid Leukemia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new combination of treatments for acute myeloid leukemia (AML), a type of blood cancer. It examines the safety and effectiveness of using a targeted radiotherapy called lintuzumab-Ac225 with two anti-cancer drugs, venetoclax and ASTX-727 (a combination of decitabine and cedazuridine). The goal is to determine if this combination can safely help more patients achieve and maintain remission. Suitable candidates include those newly diagnosed with AML, who have specific disease characteristics, such as CD33 positive cells, and are not eligible for standard aggressive chemotherapy. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, certain medications like hydroxyurea and ATRA are allowed before starting the study treatment. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that lintuzumab-Ac225, which targets certain cancer cells, was generally safe in earlier studies. Some patients experienced blood-related side effects, common among those with extensive treatment histories. Studies on venetoclax, a cancer drug that stops cancer cells from growing, found it well tolerated, especially in older patients. Previous research on the combination of decitabine and cedazuridine, which helps cancer medicine remain in the body longer, showed a safety profile similar to other treatments in its category. However, some serious side effects, such as infections and bleeding, occurred in a few cases. Overall, while some side effects have been noted with these treatments, past research suggests they are generally well-tolerated by patients.12345
Why are researchers excited about this trial's treatments?
Researchers are excited about combining targeted radiotherapy with anti-cancer drugs like Decitabine, Cedazuridine, Lintuzumab-Ac225, and Venetoclax for treating Acute Myeloid Leukemia (AML) because of its unique approach. Unlike traditional chemotherapy, which broadly attacks rapidly dividing cells, this treatment uses Lintuzumab-Ac225 to deliver radioactive particles directly to leukemia cells, potentially reducing harm to healthy cells. Venetoclax works by targeting a protein that helps cancer cells survive, while ASTX-727 (a combination of Decitabine and Cedazuridine) inhibits DNA methylation, potentially making cancer cells more vulnerable to treatment. This combination could offer a more precise and effective attack on AML cells, making it a promising alternative to current therapies.
What evidence suggests that this trial's treatments could be effective for acute myeloid leukemia?
Research has shown that adding lintuzumab-Ac225 to chemotherapy yields promising results for treating acute myeloid leukemia (AML). This trial evaluates two different schedules of this combination. In both schedules, lintuzumab-Ac225 targets specific cancer cells and uses a radioactive substance to destroy them. Venetoclax, a drug that blocks a protein aiding cancer cell survival, is included in both schedules. Studies have found that venetoclax can halt cancer growth in AML patients, with more than half of the patients achieving remission. ASTX-727, a combination of two drugs, helps create healthy blood cells and eliminate abnormal ones, with many patients reaching complete remission. Together, these treatments may improve remission rates for patients newly diagnosed with AML.16789

Are You a Good Fit for This Trial?
This trial is for adults with newly diagnosed acute myeloid leukemia (AML) who haven't had prior chemotherapy for related conditions. Participants must have AML cells that show CD33, normal bilirubin levels (unless due to Gilbert syndrome), and liver enzymes within acceptable limits. They should have a kidney function with a GFR of at least 60 ml/min/1.73 m^2, can be HIV-positive if on effective therapy, and not fit enough for intensive chemo as per their doctor's opinion.Inclusion Criteria

Trial Overview
The trial tests the combination of lintuzumab-Ac225 (a targeted radioactive antibody), venetoclax (a BCL-2 inhibitor that may stop cancer cell growth), and ASTX-727 (cedazuridine plus decitabine to help bone marrow produce healthy blood cells). It aims to determine safety, side effects, best dose, and effectiveness in treating AML.
How Is the Trial Designed?
INDUCTION: Patients receive lintuzumab-Ac225 V over 30 minutes on day 1, venetoclax PO QD on days 1-28 and ASTX-727 PO QD on days 1-5 of cycle 1. RE-INDUCTION: Patients with CR, PR or NR receive lintuzumab-Ac225 IV over 30 minutes on day 1, venetoclax PO QD on days 1-28 and ASTX-727 PO QD on days 1-5 of cycle 2. MAINTENANCE/CONSOLIDATION: Patients with CRi, CRh, or MLFS after cycle 1 receive venetoclax PO QD on days 1-28 and ASTX-727 PO QD on days 1-5 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo bone marrow aspiration and biopsy and blood sample collection throughout the study.
