Design outcomes

Primary

MeasureTime frameDescription
Mass balance of total radioactivity from [14C]-FosgonimetonSamples collected pre-dose.Total radioactivity recovery (fet1-t2)
Routes/rates of elimination of [14C]-FosgonimetonSamples collected pre-dose.Total radioactivity recovery (fet1-t2) through routes of elimination (urine and feces).
Maximum observed plasma concentration (Cmax) of ATH-1017/ATH-1001Samples 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-1001Samples 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-1001Samples 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-1001Samples collected pre-dose and at predetermined timepoints within 24 hours post-dose.t1/2 will be determined from plasma samples.

Secondary

MeasureTime frameDescription
Quantitative metabolite profiles in plasma, urine, and feces after [14C]-Fosgonimeton administrationSamples collected pre-dose and at predetermined timepoints up to 9 days post-doseQuantification of ATH-1017 major metabolites in plasma and excreta.
The chemical structure of major metabolites in plasma, urine, and feces after [14C]-Fosgonimeton administrationSamples collected pre-dose and at predetermined timepoints up to 9 days post-doseIdentification 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 subjectsSamples collected pre-dose and at predetermined timepoints up to 17 days post-doseIncidence and severity of adverse events
