What You Need to Know Before You Apply

What is the purpose of this trial?

The overall aim of this study is to determine if epigenetic priming with a DNA methyltransferase inhibitor (DMTi) prior to chemotherapy blocks is tolerable and carries evidence of a clinical efficacy signal as determined by minimal residual disease (MRD), event-free survival (EFS), and overall survival (OS). Tolerability for each of the agents, as well as total reduction in DNA methylation and outcome assessments will be done to simultaneously obtain preliminary biological and clinical data for each DMTi in parallel. PRIMARY OBJECTIVES: * Evaluate the tolerability of five days of epigenetic priming with azacitidine and decitabine as a single agent DMTi prior to standard AML chemotherapy blocks. * Evaluate the change in genome-wide methylation burden induced by five days of epigenetic priming and the association of post-priming genome-wide methylation burden with event-free survival among pediatric AML patients. SECONDARY OBJECTIVES * Describe minimal residual disease levels following Induction I chemotherapy in patients that receive DMTi. * Estimate the event-free survival and overall survival of patients receiving a DMTi prior to chemotherapy courses.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications, but it does mention that you cannot use other chemotherapy, radiation, or immunotherapy during the study. It's best to discuss your current medications with the trial team.

Is epigenetic priming with decitabine safe for humans?

Decitabine, used in epigenetic priming for acute myeloid leukemia, has been shown to be generally safe in humans, with side effects similar to standard chemotherapy. Some studies noted more gastrointestinal issues with longer treatment durations, but overall, it was well tolerated. ^{1 2 3 4 5}

What makes the drug Azacitidine and Decitabine unique for treating acute myeloid leukemia?

This drug combination is unique because it uses 'epigenetic priming' to prepare cancer cells for chemotherapy by altering their DNA methylation, which can reactivate genes that suppress tumors. This approach aims to improve the effectiveness of standard chemotherapy in patients with acute myeloid leukemia. ^{3 4 5 6 7}

What data supports the effectiveness of the drug Azacitidine, Vidaza, 5-azacytidine, Decitabine, Decitabine, Dacogen, ASTX727 (when combined with cedazuridine) for treating Acute Myeloid Leukemia?

Research shows that azacitidine and decitabine, which are part of the treatment, have been effective in treating acute myeloid leukemia (AML) by reactivating genes that suppress tumors and stopping cancer cell growth. Clinical trials have demonstrated that these drugs can extend survival and delay relapse in AML patients, especially when used in combination with other agents. ^{4 5 8 9 10}

Published Research Related to This Trial

The optimal biologic dose (OBD) of decitabine for treating acute myeloid leukemia (AML) was determined to be 20 mg/m²/day, which showed limited nonhematologic toxicity and promising clinical activity, with a response rate of 44% among 25 patients.

Combining decitabine with valproic acid (VA) resulted in dose-limiting encephalopathy at lower doses of VA, indicating safety concerns, while the clinical responses were similar whether patients received decitabine alone or in combination with VA.

Decitabine is an effective hypomethylating agent for treating acute myeloid leukemia (AML), significantly improving overall survival and response rates compared to standard care, based on results from the phase 3 DACO-016 trial with adult patients who are not eligible for standard chemotherapy.

The treatment is generally well tolerated and remains effective even in patients with adverse-risk karyotypes or TP53 mutations, making it a valuable option for those unfit for more intensive therapies, with potential for future combination treatments.
