研究概览
简要总结
This is a single-center, non-randomized, open-label, single-cohort, single-dose phase I clinical study in healthy Chinese adult male subjects.
详细描述
The main objectives of this study were as follows:
- To quantitatively analyze the total radioactivity in excreta of healthy subjects after a single oral administration of [14C]SIM0270, and to obtain the data of human radioactive excretion rate and main excretion routes.
- After a single oral administration of [14C]SIM0270 in healthy subjects, radioactive metabolite profiles in plasma, urine and feces were investigated to identify metabolites, and the metabolic pathway, main metabolites and elimination pathway of SIM0270 in human body were determined.
- The total radioactivity in whole blood and plasma of healthy subjects after a single oral administration of [14C]SIM0270 was quantitatively analyzed, the pharmacokinetic characteristics of total radioactivity in plasma were evaluated, and the distribution of total radioactivity in whole blood and plasma was investigated.
