Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mass balance of total radioactivity from [14C]-Fosgonimeton | Samples collected pre-dose. | Total radioactivity recovery (fet1-t2) |
| Routes/rates of elimination of [14C]-Fosgonimeton | Samples collected pre-dose. | Total radioactivity recovery (fet1-t2) through routes of elimination (urine and feces). |
| Maximum observed plasma concentration (Cmax) of ATH-1017/ATH-1001 | Samples collected pre-dose and at predetermined timepoints within 24 hours post-dose. | Cmax will be determined from plasma samples. |
| Time to maximum observed plasma concentration (Tmax) of ATH-1017/ATH-1001 | Samples collected pre-dose and at predetermined timepoints within 24 hours post-dose. | Tmax will be determined from plasma samples |
| Area under the plasma concentration time curve (AUC) for of ATH-1017/ATH-1001 | Samples collected pre-dose and at predetermined timepoints within 24 hours post-dose. | AUC will be determined from plasma samples. |
| Half-life (t1/2) of ATH-1017/ATH-1001 | Samples collected pre-dose and at predetermined timepoints within 24 hours post-dose. | t1/2 will be determined from plasma samples. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quantitative metabolite profiles in plasma, urine, and feces after [14C]-Fosgonimeton administration | Samples collected pre-dose and at predetermined timepoints up to 9 days post-dose | Quantification of ATH-1017 major metabolites in plasma and excreta. |
| The chemical structure of major metabolites in plasma, urine, and feces after [14C]-Fosgonimeton administration | Samples collected pre-dose and at predetermined timepoints up to 9 days post-dose | Identification of ATH-1017 major metabolites in plasma (\>10% relative total drug-related exposure) and excreta (\>10% of excreted dose) |
| Incidence and severity of adverse events (safety and tolerability) of [14C]-Fosgonimeton when administered to healthy subjects | Samples collected pre-dose and at predetermined timepoints up to 17 days post-dose | Incidence and severity of adverse events |
