A Prospective, Single-arm, Exploratory Clinical Study of Sintilimab Injection in Combination With Paclitaxel (Albumin-bound) and Gemcitabine in Translational Therapy in Patients With Unresectable Locally Advanced Pancreatic Cancer.

This is a prospective, single-arm, single-center clinical study to investigate the efficacy and safety of sintilimab in combination with gemcitabine and albumin-paclitaxel conversion therapy with unresectable locally advanced pancreatic cancer. The primary endpoint is R0-surgery resection rate. Objective response rate, overall survival , progression-free survival, event free survival, adverse events will be recorded and analyzed, to assess the efficacy and safety of the combination treatment with sintilimab and paclitaxel (albumin-bound) and gemcitabine with metastatic pancreatic cancer. The study will also explore biomarkers that can predict efficacy, and blood and tumor samples will be collected/collected at baseline and during the trial for patients who sign informed consent, including possible tumor biopsies at baseline.
