Efficacy of First-Line Gemcitabine Chemotherapy in GemCore+ Metastatic Pancreatic Adenocarcinoma Patients (GemSign-01)

June 10, 2025 updated by: Institut Paoli-Calmettes

Phase IV Study Assessing Efficacy of First-Line Chemotherapy With Gemcitabine in GemCore+ Metastatic Pancreatic Adenocarcinoma Patients Ineligible to FOLFIRINOX Treatment

The goal of this interventional study is to learn about the efficacy of first-line chemotherapy with Gemcitabine in metastatic pancreatic adenocarcinoma patients expressing the GemCore signature in their tumor. The main question it aims to answer is to assess efficacy of Gemcitabine (tumor response, survival rate) in the population of patient bearing the GemCore signature.

Participants will start the chemotherapy with Gemcitabine as usually performed in standard care of their center. They will consent to a genomic analyze of their tumor to know if it bears the GemCore signature. The center will manage the participant's follow up as usually realized in standard care.
