Summary
The 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.
Eligibility
Inclusion Criteria5
- Histologically confirmed metastatic colorectal adenocarcinoma (mCRC).
- Received EGFR-targeted therapy (cetuximab/panitumumab) or VEGF-targeted therapy (bevacizumab).
- Availability of pre-treatment plasma sample for cfDNA analysis.
- Documented radiologic response evaluation (RECIST 1.1).
- RAS/BRAF mutation status known.
Exclusion Criteria4
- Inadequate cfDNA quality or low cfDNA yield.
- Non-adenocarcinoma histology.
- Concurrent or prior other active malignancy.
- Active inflammatory or autoimmune disease affecting cfDNA methylation profiles.
Interventions
High-throughput genome-wide sequencing of cfDNA methylation (5mC) and hydroxymethylation (5hmC) profiles from pre-treatment plasma samples in the discovery cohort to identify epigenetic determinants of targeted-therapy response (PFS ≥ 12 months vs \< 12 months).
Targeted sequencing or qPCR-based validation of cfDNA 5mC/5hmC markers identified from the discovery phase to develop and validate a predictive biomarker model discriminating patients with long vs short progression-free survival after EGFR-/VEGF-targeted therapy.
