About this study
Official title: Development of a cfDNA 5mC/5hmC-based Epigenetic Biomarker Panel to Identify Determinants of Response In VEGF/EGFR-targeted Therapy for Metastatic Colorectal Cancer
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.
Read the detailed description
Metastatic colorectal cancer (mCRC) remains one of the leading causes of cancer-related death. Although targeted agents such as anti-EGFR (cetuximab, panitumumab) and anti-VEGF (bevacizumab) therapies have improved survival, treatment response varies widely even among molecularly defined subgroups.
Traditional biomarkers, including RAS/BRAF mutation and tumor sidedness, fail to accurately predict therapeutic efficacy.
Recent studies highlight the potential of cell-free DNA (cfDNA) methylation (5mC) and hydroxymethylation (5hmC) as sensitive, non-invasive indicators of tumor biology and treatment dynamics.
The EpiDRIVE study integrates cfDNA 5mC/5hmC sequencing and targeted validation to discover and verify epigenetic determinants of therapeutic response.
Discovery phase: Whole-genome 5mC/5hmC profiling to identify differentially modified regions between responders and non-responders.
Training phase: Targeted sequencing to establish a predictive cfDNA epigenetic panel (EpiDRIVE panel).
Validation phase: qPCR-based validation of selected markers in an independent cohort to confirm predictive accuracy.
This study aims to provide a non-invasive biomarker framework to predict and monitor efficacy of EGFR- and VEGF-targeted therapies in mCRC, ultimately guiding personalized treatment selection.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
cfDNA 5mC/5hmC Sequencing (EpiDRIVE Discovery Phase)Diagnostic test
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).
EpiDRIVE Assay (Targeted Sequencing / qPCR Validation)Diagnostic test
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.
| Study group | Role | What they receive |
|---|---|---|
| Discovery Cohort - Long PFS Group (Responder) | Patients with metastatic colorectal cancer (mCRC) who received EGFR- or VEGF-targeted therapy and achieved a progression-free survival (PFS) ≥ 12 months, classified as clinical responders.
Pre-treatment plasma cfDNA samples were analyzed by genome-wide 5mC/5hmC sequencing to identify epigenetic determinants associated with durable treatment response. Receives: Diagnostic Test: cfDNA 5mC/5hmC Sequencing (EpiDRIVE Discovery Phase) | |
| Discovery Cohort - Short PFS Group (Non-Responder) | Patients with mCRC who received EGFR- or VEGF-targeted therapy and showed progression-free survival (PFS) < 12 months, classified as non-responders.
Pre-treatment cfDNA samples were analyzed using genome-wide 5mC/5hmC sequencing and compared with long-PFS responders to identify differential methylation and hydroxymethylation patterns associated with resistance. Receives: Diagnostic Test: cfDNA 5mC/5hmC Sequencing (EpiDRIVE Discovery Phase) | |
| Training Cohort - Long PFS Group (Responder) | Independent mCRC cohort with PFS ≥ 12 months following EGFR- or VEGF-targeted therapy.
Candidate cfDNA 5mC/5hmC markers identified in the discovery phase were validated using targeted sequencing (EpiDRIVE assay) to construct the predictive epigenetic biomarker panel. Receives: Diagnostic Test: EpiDRIVE Assay (Targeted Sequencing / qPCR Validation) | |
| Training Cohort - Short PFS Group (Non-Responder) | Independent mCRC patients with PFS < 12 months after targeted therapy. Targeted sequencing using the EpiDRIVE assay was conducted to refine and optimize the predictive model by comparing short- vs long-PFS cases. Receives: Diagnostic Test: EpiDRIVE Assay (Targeted Sequencing / qPCR Validation) | |
| Validation Cohort - Long PFS Group (Responder) | Separate validation cohort of mCRC patients achieving PFS ≥ 12 months under EGFR- or VEGF-targeted therapy.
qPCR-based EpiDRIVE assay was used to confirm predictive accuracy of the cfDNA 5mC/5hmC biomarker panel in identifying durable responders. Receives: Diagnostic Test: EpiDRIVE Assay (Targeted Sequencing / qPCR Validation) | |
| Validation Cohort - Short PFS Group (Non-Responder) | Independent validation cohort of mCRC patients with PFS < 12 months after targeted therapy.
cfDNA was analyzed using the qPCR-based EpiDRIVE assay to assess model specificity and distinguish non-responders from long-term responders. Receives: Diagnostic Test: EpiDRIVE Assay (Targeted Sequencing / qPCR Validation) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-Free Survival (PFS) according to cfDNA 5mC/5hmC biomarker profile
Progression-free survival (PFS) among patients with metastatic colorectal cancer (mCRC) receiving EGFR- or VEGF-targeted therapy, stratified by cfDNA 5mC/5hmC-based biomarker status.
Measured: Up to 36 months from therapy initiation
Secondary outcomes (1)
Overall Survival (OS)
Time from initiation of EGFR- or VEGF-targeted therapy to death from any cause. Overall survival will be analyzed in relation to cfDNA 5mC/5hmC biomarker-defined groups (high vs low EpiDRIVE score) to assess whether epigenetic cfDNA profiles are associated with differences in survival outcomes.
Measured: Up to 60 months from therapy initiation
