Study summary

This goal of this trial is to learn about two medicines, enlicitide and rosuvastatin, in healthy people. Researchers will compare the amounts of enlicitide and rosuvastatin in a person's body over time, when they are given as separate medicines and when they are combined into one tablet.

What researchers measure

Primary outcomes

  1. Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-Inf) of Enlicitide

    Blood samples will be collected to determine the AUC0-inf of enlicitide in plasma

    Time frame: Pre dose and at designated time points up to 168 hours post dose

  2. AUC0-Inf of Rosuvastatin

    Blood samples will be collected to determine the AUC0-inf of rosuvastatin in plasma

    Time frame: Pre dose and at designated time points up to 168 hours post dose

  3. Area Under the Concentration-Time Curve from Time 0 to Last (AUC0-Last) of Enlicitde

    Blood samples will be collected to determine the AUC0-last of enlicitide in plasma

    Time frame: Pre dose and at designated time points up to 168 hours post dose

  4. AUC0-Last of Rosuvastatin

    Blood samples will be collected to determine the AUC0-last of rosuvastatin in plasma

    Time frame: Pre dose and at designated time points up to 168 hours post dose

  5. Maximum Plasma Concentration (Cmax) of Enlicitide

    Blood samples will be collected to determine the cmax of enlicitide in plasma

    Time frame: Pre dose and at designated time points up to 168 hours post dose

  6. Cmax of Rosuvastatin

    Blood samples will be collected to determine the cmax of rosuvastatin in plasma

    Time frame: Pre dose and at designated time points up to 168 hours post dose

Secondary outcomes

  1. Number of Participants who Experience an Adverse Event (AE)

    An 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.

    Time frame: Up to approximately 9 weeks

  2. Number of Participants Who Discontinue Study Treatment Due to an AE

    An 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.

    Time frame: Up to approximately 8 days after first dose
