Brief summary
This study is a single-center, open-label, single-dose design. It is planning to enroll six Chinese healthy adult male subjects. The metabolism and disposition of Herombopag, will be studied in these subjects after a single oral administration of a solution dose of \[14C\] Herombopag (5 mg, 100 uCi).
Detailed description
The metabolism and disposition of Herombopag, will be studied in six healthy men after a single oral administration of a solution dose of \[14C\]eltrombopag (5 mg,100 uCi). The sutdy will investigate total radioactivity pharmacokinetics in whole blood and plasma 、quantitatively analyze the the total radioactivity in the excreta、evaluate the predominant route of elimination and indentify the Metabolite profiles in plasma 、urine and faces.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total radioactivity pharmacokinetics in whole blood and plasma | From 1 hour before administration to 240 hours after administration | plasma concentration of total radioactivity |
| total radioactivity in the excreta | From 24 hour before administration to 336 hours after administration | Excretion of radioactivity in human urine and feces |
| the concentration of Hetrombopag in plasma | From 1 hour before administration to 240 hours after administration | Area under the plasma concentration versus time curve (AUC) |
| individual metabolite profiles in plasma 、urine and faces | From 24 hour before administration to 336 hours after administration | Using quantitative High Performance Liquid Chromatography-Mass Spectroscopic method to analyse individual percentage of metabolites. |
| mean metabolite profiles in plasma 、urine and faces | From 24 hour before administration to 336 hours after administration | Using quantitative High Performance Liquid Chromatography-Mass Spectroscopic method to analyse mean percentage of metabolites. |
