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.
Based on the tolerability, safety and pharmacokinetics phase I/II clinical trials of ulimostat hydrochloride capsules (LH011) combined with gemcitabine hydrochloride (GEM) in locally advanced/metastatic pancreatic cancer patients, to determine pharmacokinetics, the biotransformation pathway and metabolite profile of ulimostat in patients with locally advanced/metastatic pancreatic cancer.
