Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Elimination half-life | Up to 90 hours post dose | Total radioactivity in plasma PK: T1/2 |
| Mass Balance | Screening period (-48 hours) to 240 hours | Mass balance recovery of total radioactivity in urine and fecal samples. |
| [14C] CS0159 metabolite | Screening period (-48 hours) to 240 hours | Identification of the major metabolites of CS0159 in human plasma, urine and faeces, determine the main Determine the main biotransformation pathways and calculate the percentage of the administered dose of the prodrug and each metabolite in urine and faeces, and plasma prodrugs and circulating metabolites as a percentage of total exposure AUC. |
| Radioactivity of CS0159 | Up to 90 hours post dose | Whole blood to plasma total radioactivity ratio |
| Area under the curve | Up to 90 hours post dose | Total radioactivity in plasma PK: AUC |
| Highest radioactivity observed plasma concentration | Up to 90 hours post dose | Total radioactivity in plasma PK: Cmax |
| Time for Cmax | Up to 90 hours post dose | Total radioactivity in plasma PK: Tmax |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cmax of CS0159 | Up to 90 hours post dose | Highest observed plasma concentration of CS0159 |
| Blood plasma PK | Up to 90 hours post dose | other major metabolites in plasma( if any). |
| T1/2 of CS0159 | Up to 90 hours post dose | Elimination half-life of CS0159 |
| Adverse events | Up to 240 hours post dose | All subjects will be assessed for incidence and severity of adverse events (AEs) and serious AEs |
| AUC of CS0159 | Up to 90 hours post dose | Area under the plasma concentration time curve of CS0159 |
| Tmax of CS0159 | Up to 90 hours post dose | Time for Cmax of CS0159 |
