This study is a research on the pharmacokinetics and gene polymorphisms of ulimostat hydrochloride capsules in patients with locally advanced/metastatic pancreatic cancer. Aims to collect the "Phase I/II clinical trials of the tolerability, safety and pharmacokinetics of ulimostat capsules (LH011) combined with gemcitabine hydrochloride (GEM) in patients with locally advanced/metastatic pancreatic cancer" patient's peripheral blood sample to determine the structure of the metabolites of ulimostat in the biological samples and trough concentration and genotyping tests were performed on patients to investigate the correlation between gene polymorphisms of metabolic enzymes, transporters, target protein uPA and proteins expressed in upstream and downstream signaling pathways and blood drug concentration, efficacy, safety and tolerance of ulimostat.
