Brief summary

The purpose of this study is to learn what happens to enlicitide chloride labeled with \[¹⁴C\] in a person's body over time. A label can be added to a study medicine to trace it in a person's body.

MeasureTime frameDescription
Enlicitide Chloride to Total Radioactivity Ratio of Area Under the Concentration-Time Curve from Time 0 to the Last Detectable Sample (enlicitide chloride AUC0-x/total radioactivity AUC0-x)At designated timepoints (up to 15 days)Plasma samples will be collected to determine the enlicitide chloride AUC0-x/total radioactivity AUC0-x.
Plasma Total Reactivity: t1/2At designated timepoints (up to 15 days)Plasma samples will be collected to determine the t1/2 of total reactivity.
Plasma Total Reactivity: TmaxAt designated timepoints (up to 15 days)Plasma samples will be collected to determine the Tmax of total reactivity.
Cumulative Amount of Radioactivity Excreted in Urine (Aeu)At designated timepoints (up to 15 days)Urine samples will be collected to determine the Aeu of \[¹⁴C\]enlicitide chloride.
Cumulative Amount of Radioactivity Excreted in Feces (Aef)At designated timepoints (up to 15 days)Fecal samples will be collected to determine the Aef of \[¹⁴C\]enlicitide chloride.
Cumulative Percentage of Radioactivity Excreted in Urine (feu)At designated timepoints (up to 15 days)Urine samples will be collected to determine the feu of \[¹⁴C\]enlicitide chloride.
Cumulative Percentage of Radioactivity Excreted in Feces (fef)At designated timepoints (up to 15 days)Fecal samples will be collected to determine the fef of \[¹⁴C\]enlicitide chloride.
Plasma Enlicitide Chloride: Area Under the Concentration-Time Curve from Time 0 to the Last Measurable Concentration (AUC0-t)At designated timepoints (up to 15 days)Plasma samples will be collected to determine the AUC0-t of enlicitide chloride.
Plasma Enlicitide Chloride: Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-inf)At designated timepoints (up to 15 days)Plasma samples will be collected to determine the AUC0-inf of enlicitide chloride.
Plasma Enlicitide Chloride: Maximum Plasma Concentration (Cmax)At designated timepoints (up to 15 days)Plasma samples will be collected to determine the Cmax of enlicitide chloride.
Plasma Enlicitide Chloride: Apparent Terminal Half-life (t1/2)At designated timepoints (up to 15 days)Plasma samples will be collected to determine the t1/2 of enlicitide chloride.
Plasma Enlicitide Chloride: Time to Maximum Plasma Concentration (Tmax)At designated timepoints (up to 15 days)Plasma samples will be collected to determine the Tmax of enlicitide chloride.
Plasma Total Reactivity: AUC0-tAt designated timepoints (up to 15 days)Plasma samples will be collected to determine the AUC0-t of total reactivity.
Plasma Total Reactivity: AUC0-infAt designated timepoints (up to 15 days)Plasma samples will be collected to determine the AUC0-inf of total reactivity.
Plasma Total Reactivity: CmaxAt designated timepoints (up to 15 days)Plasma samples will be collected to determine the Cmax of total reactivity.
