Brief summary

The goal of this trial is to learn what happens to different formulations (types) of enlicitide in a healthy person's body over time. Researchers will compare the amount of enlicitide in a healthy person's body over time when different formulations are given on an empty stomach and after a high-fat meal.

Design outcomes

Primary

MeasureTime frameDescription
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinity (AUC0-inf) of Enlicitide in PlasmaPre-dose and at designated timepoints (up to 168 hours post dose)Blood samples will be collected to determine the AUC0-inf of enlicitide.
Maximum Observed Plasma Concentration (Cmax) of Enlicitide in PlasmaPre-dose and at designated timepoints (up to 168 hours post dose)Blood samples will be collected to determine the Cmax of enlicitide.

Secondary

MeasureTime frameDescription
AUC0-inf of Enlicitide in Plasma Under Fed vs Fasted ConditionsPre-dose and at designated timepoints (up to 168 hours post dose)Blood samples will be collected to determine the AUC0-inf of enlicitide under fed and fasted conditions.
Cmax of Enlicitide in Plasma Under Fed vs Fasted ConditionsPre-dose and at designated timepoints (up to 168 hours post dose)Blood samples will be collected to determine the Cmax of enlicitide under fed and fasted conditions.
Number of Participants Who Experience an Adverse Event (AE)Up to approximately 98 daysAn AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who experience an AE will be reported.
Number of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 98 daysAn AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who discontinue study treatment due to an AE will be reported.
