Azacitidine + Chemotherapy for Acute Lymphoblastic Leukemia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the effectiveness of combining azacitidine, a chemotherapy drug, with various other chemotherapy drugs in infants with acute lymphoblastic leukemia involving a specific genetic change called KMT2A rearrangement. Researchers aim to determine if using multiple drugs together can kill more cancer cells and identify any side effects. Eligible infants have newly diagnosed B lymphoblastic leukemia or a similar condition, have not received other cancer treatments besides steroids or specific chemotherapy, and do not have conditions like Down syndrome. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group, providing an opportunity to contribute to important findings.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, it mentions that prior cytotoxic chemotherapy is not allowed, except for certain steroids and specific chemotherapy drugs given directly into the spinal fluid.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that azacitidine is safe and well-tolerated in infants with acute lymphoblastic leukemia, particularly those with a specific gene change called KMT2A rearrangement. One study found that azacitidine reduced DNA methylation, which affects gene function, in these infants without causing significant harm. Previous patients have demonstrated that azacitidine can be safely combined with chemotherapy for this condition.
The other drugs in the trial, such as methotrexate, daunorubicin, and cytarabine, are standard chemotherapy medications. They have known side effects, which are usually managed during treatment. By using a combination of drugs, doctors aim to kill more cancer cells while carefully monitoring for any side effects.12345Why are researchers excited about this trial's treatments?
Unlike the standard chemotherapy regimens for acute lymphoblastic leukemia (ALL), which typically focus on directly killing cancer cells, the addition of azacitidine offers a new approach by targeting the epigenetic changes in cancer cells. Azacitidine works by modifying the DNA of leukemia cells, potentially reactivating genes that suppress tumor growth. This unique mechanism can make cancer cells more sensitive to traditional chemotherapy, potentially improving outcomes. Researchers are excited because this combination might enhance the effectiveness of existing treatments, offering hope for better remission rates in patients with ALL.
What evidence suggests that this trial's treatments could be effective for acute lymphoblastic leukemia?
Research has shown that azacitidine, which participants in this trial will receive alongside chemotherapy, holds promise for treating acute lymphoblastic leukemia, particularly in infants with a specific genetic change called KMT2A gene rearrangement. Studies have found that azacitidine can be safely and effectively combined with chemotherapy, aiding patients in achieving complete remission, where no signs of cancer are detected. Infants with this genetic condition have experienced positive outcomes. While azacitidine alone has demonstrated a complete response rate of about 15–20% in some studies, it appears to enhance leukemia cells' response to chemotherapy, making the overall treatment more effective. This combination aims to halt the growth, division, or spread of cancer cells, thereby increasing the chances of remission.36789

Are You a Good Fit for This Trial?
This trial is for infants over 36 weeks gestational age with newly diagnosed B lymphoblastic leukemia or acute leukemia of ambiguous lineage, without Down syndrome or prior malignancies treated with cytotoxic chemotherapy. They must not have received previous cancer treatments, except certain steroids and intrathecal drugs.Inclusion Criteria
