Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Distribution ratio of total radioactivity in whole blood and plasma of [14C] Antaitavir Hasophate | up to 15 days | To investigate the pharmacokinetics of total radioactivity in plasma after oral \[14C\] Antaitavir Hasophate in healthy subjects, and the distribution ratio of total radioactivity in whole blood and plasma |
| Cumulative excretion of [14C] Antaitavir Hasophate -related material (radioactivity in plasma, urine and fecal samples) | up to 15 days | Percent (%) of each radiolabeled drug-related material (parent and each metabolite) will be determined in plasma, urine and feces. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Identification of the Proportion of different metabolites to determine biotransformation pathway of Antaitavir Hasophate | up to 15 days | Proportion of different metabolites(Antaitavir Hasophate and main metabolites) |
| Quantitive analysis of the concentrations of Antaitavir Hasophate and main metabolites in plasma using the validated LC-MS/MS to obtain pharmacokinetic data | up to 15 days | The concentrations of Antaitavir Hasophate and main metabolites in plasma |
| Number of adverse events (AE) experienced by subjects | up to 15 days | To examine the safety and tolerability of \[14C\] Antaitavir Hasophate given orally |
