Our study is a prospective, multicenter, randomized controlled clinical study included patients with stage IV pancreatic ductal adenocarcinoma receiving gemcitabine-based first-line combination therapy according to the 2022 NCCN guidelines and with an estimated survival of \> 3 months. According to reports and previous research results, we plan to include 306 subjects, and the subjects will divide into experimental group and the control group by a ratio of 1:1. All patients in the treatment group will receive QingyiHuaji optimized formula and standard treatment, and patients in the control group will receive placebo combined with standard treatment. Overall survival (OS) is defined as the primary endpoint, and progression-free survival (DFS), quality of life of cancer patients, and relief rate of TCM symptoms are considered as the secondary endpoint to observe the clinical efficacy of Qingyihuaji optimized formula combined with standard chemotherapy for stage IV pancreatic ductal adenocarcinoma. It will provide high-level evidence-based medical basis for the clinical effect of Qingyihuayi optimization prescription on pancreatic cancer with damp-heat accumulation syndrome. The hypothesis of this study is that the combination of Qingyihuaji optimized prescription with standard chemotherapy has the advantage of significantly prolonging the overall survival time, and is feasible and safe for the subjects diagnosed with stage IV pancreatic ductal adenocarcinoma by cytology or histology. The study lasted for 32 months, from 2023 April to December 2025.
