Brief summary

The goal of this study is to learn what happens to enlicitide in a person's body over time when enlicitide is taken at the same time as coffee or tea. Researchers will measure the amount of enlicitide in the blood when taken with coffee or tea compared with enlicitide taken with water.

Interventions

Single dose of enlicitide is administered orally on day 1 of each testing period

MeasureTime frameDescription
Part 2 -Tea: Cmax of EnlicitidePredose and at designated time points up to 168 hoursBlood samples will be collected to determine the maximum observed drug concentration of enlicitide when administered with tea
Part 1-Coffee: Area Under the Concentration-Time Curve from Time 0 to Last (AUC0-last) of EnlicitidePredose and at designated time points up to 168 hoursBlood samples will be collected to determine the AUC from time 0 to the time of last quantifiable sample of enlicitide when administered with coffee
Part 1 -Coffee : Maximum Plasma Concentration (Cmax) of EnlicitidePredose and at designated time points up to 168 hoursBlood samples will be collected to determine the maximum observed drug concentration of enlicitide when administered with coffee
Part 2 -Tea: AUC0-last of EnlicitidePredose and at designated time points up to 168 hoursBlood samples will be collected to determine the AUC from time 0 to the time of last quantifiable sample of enlicitide when administered with tea
Part 2 - Tea: AUC0-Inf of EnlicitidePredose and at designated time points up to 168 hoursBlood samples will be collected to determine the AUC0-inf of enlicitide when administered with tea.
Part 1-Coffee: Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-Inf) of EnlicitidePredose and at designated time points up to 168 hoursBlood samples will be collected to determine the AUC0-inf of enlicitide when administered with coffee

MeasureTime frameDescription
Part 2 - Tea: Number of Participants Who Experience an Adverse Event (AE)Up to approximately 7 weeksAn AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be reported.
Part 1 - Coffee: Number of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 7 weeksAn 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.
Part 2 - Tea: Number of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 7 weeksAn 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.
