Predicting chemotherapy response in pancreatic cancer using a blood microRNA panel

An Exosomal miRNA Based Predictive Model for Personalized Neoadjuvant Chemotherapy Selection in Pancreatic Ductal Adenocarcinoma

Observational City of Hope Medical Center · NCT07226154

This project tests whether a panel of microRNAs in pre-treatment blood can predict response to neoadjuvant chemotherapy (FOLFIRINOX or gemcitabine plus nab‑paclitaxel) in patients with resectable or borderline resectable pancreatic cancer.

What this trial studies

PRECEPT is a retrospective, non-interventional analysis using archived pre-treatment plasma from patients with resectable or borderline resectable pancreatic ductal adenocarcinoma who received neoadjuvant FOLFIRINOX or gemcitabine plus nab‑paclitaxel and subsequently underwent curative-intent surgery. Investigators performed exosomal small RNA sequencing to identify candidate microRNAs and will validate selected candidates by qRT-PCR in an independent cohort. The study will correlate pre-treatment miRNA levels with pathologic response (CAP grade or tumor regression score) and explore associations with overall survival and recurrence-free survival. All analyses are performed on existing biospecimens and clinical records without additional interventions.

Who should consider this trial

Good fit: Ideal candidates are patients with histologically confirmed PDAC who had pre-treatment plasma available, received standard neoadjuvant FOLFIRINOX or gemcitabine plus nab‑paclitaxel, and underwent curative-intent resection.

Not a fit: Patients with metastatic disease, non-adenocarcinoma histology, those who received nonstandard chemotherapy regimens, or who lack good-quality pre-treatment plasma samples are unlikely to benefit from this analysis.

Why it matters

Potential benefit: If successful, the miRNA panel could help doctors choose the chemotherapy most likely to work for an individual patient and spare others from ineffective treatment.

How similar studies have performed: Prior small studies and exploratory reports have suggested circulating or exosomal miRNAs can correlate with chemotherapy response in PDAC, but no widely validated predictive miRNA panel currently exists.
