Personalize (Signature Driven) Neoadjuvant Chemotherapy Trial for Patients With Resectable Borderline Pancreatic Ductal Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) exhibits significant heterogeneity, making the optimal choice of chemotherapy challenging. While targeted therapies benefit from companion biomarkers, few tools exist to guide the selection of cytotoxic chemotherapy. Transcriptomic signatures now allow for the prediction of sensitivity to cytotoxic agents. Several molecular classifications (such as basal-like, classical, etc.) have been established and correlated with prognosis, but they are rarely used in clinical practice. The PaCaOmics program has developed robust predictive signatures, grouped under the name Pancreas-View Signature, capable of analyzing FFPE samples using minimal material. Locally advanced or borderline resectable pancreatic cancer (BR-PDAC) accounts for approximately 20% of cases. Neoadjuvant chemotherapy (NAC) has become the standard of care, improving R0 resection rates and overall survival. The two main chemotherapy regimens used are mFOLFIRINOX and GEM/NAB-paclitaxel, which show comparable efficacy and toxicity profiles. However, no clear consensus exists on the superiority of one over the other. Therefore, predictive biomarkers are crucial to help select the most appropriate neoadjuvant regimen, avoid unnecessary toxicities, and maximize the chances of curative surgery. The NEOPREDICT trial aims to evaluate the efficacy of treating patients with borderline resectable PDAC identified with a GEM+ sensitivity transcriptomic signature with GEMCITABINE + NAB-PACLITAXEL regimen compared to standard of care mFOLFIRINOX as NAC.
