RecruitingDiagnostic testDevelopment of a cfDNA 5mC/5hmC-based Biomarker Panel to Predict Targeted Therapy Efficacy in mCRCThe EpiDRIVE study aims to identify cfDNA-based epigenetic determinants of response in metastatic colorectal cancer (mCRC) patients treated with EGFR- or VEGF-targeted therapy. By integrating 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) profiling, this study seeks to develop a predictive biomarker panel capable of differentiating responders from non-responders to targeted therapy.
