Evaluation of the Efficacy of Hypomethylating Agent Versus Standard Intensive Chemotherapy Induction Based on 5hmC - a Novel, Blood Epigenetic Marker for Assessing Measurable Residual Disease in Patients With Acute Myeloid Leukemia
The Methodist Hospital Research Institute
Summary
This is a therapeutic intervention trial evaluating the clinical utility of a novel blood-based epigenetic biomarker-genome-wide 5-hydroxymethylcytosine (5hmC) in cell-free DNA (cfDNA)-for assessing measurable residual disease (MRD) in patients with newly diagnosed acute myeloid leukemia (AML). The study compares the efficacy of hypomethylating agent (HMA)-based therapy versus intensive induction chemotherapy, using the 5hmC biomarker to guide post-induction treatment decisions. Approximately 112 adult patients will be enrolled and assigned to treatment arms based on a stratified sampling scheme. Blood samples will be collected at defined intervals to assess MRD status. Primary endpoints include minimal residual disease (MRD) negativity rate, duration of remission, event-free survival (EFS), and overall survival (OS).
Description
This is a therapeutic intervention trial evaluating the efficacy of a novel, blood epigenetic marker \[genome-wide 5 hydroxymethylcytosine (5hmC) of cell free DNA (cfDNA)\] for assessing measurable residual disease (MRD) in patients with acute myeloid leukemia (AML). Using the highly sensitive cfDNA 5hmC method, the trial will evaluate clinical efficacy of induction therapy and minimal residual disease (MRD) guided therapy in AML patients. Female or male patients aged 18 years, or older, with newly diagnosed de novo AML who will receive induction therapy with either hypomethylating agent (HMA)…
