Researchers have designed a new study medicine called enlicitide decanoate as a new way to lower the amount of low-density lipoprotein cholesterol (LDL-C) in a person's blood. Enlicitide decanoate will be called "enlicitide" from this point forward, The purpose of this study is to learn what happens to enlicitide in a person's body over time (a pharmacokinetic or PK study). Researchers will compare what happens to enlicitide in the body when it is given to people with hepatic impairment (HI- meaning the liver does not work properly) and people who are in good health. This study will have 2 parts. In Part 1, enlicitide will be given to people with moderate HI and people who are in good health. After Part 1, researchers may decide to include people who have mild HI and compare what happens to enlicitide in the body with people who are in good health.

Area Under the Concentration Versus Time Curve From Time 0 to Infinity (AUC0-inf) of Enlicitide
Blood samples were collected at pre-specified time points to determine the AUC0-inf of enlicitide in plasma. AUC0-inf was defined as AUC0-last + (Cest,last/λz) where Cest, last was the estimated last measurable concentration, and λz was the apparent first-order terminal elimination rate constant.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, 24, 36, 48, 72, 120, and 168 hours postdose
Maximum Concentration (Cmax) of Enlicitide
Blood samples were collected at pre-specified time points to determine the Cmax of enlicitide in participant's plasma. Cmax was defined as the maximum observed concentration of enlicitide in plasma after the administration of a given dose.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, 24, 36, 48, 72, 120, and 168 hours postdose
Area Under the Concentration Versus Time Curve From Time 0 to 24 Hours (AUC0-24) of Enlicitide
Blood samples were collected at pre-specified time points to determine the AUC0-24 of encilitide. AUC0-24 of encilitide was defined as the area under the concentration-time curve from time 0 to the 24 hours after the dosing of encilitide.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, and 24 hours postdose
Area Under the Concentration Versus Time Curve From Time 0 to Last (AUC0-last) of Enlicitide in Plasma
Blood samples were collected at pre-specified time points to determine the AUC0-last of enlicitide in participant's plasma. AUC0 to last of enlicitide was defined as the area under the concentration-time curve from time 0 to the time of the last quantifiable (above lower limit of quantitation) concentration. AUC0-last was calculated using noncompartmental analysis.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, 24, 36, 48, 72, 120, and 168 hours postdose
Time to Maximum (Tmax) Observed Plasma Drug Concentration of Enlicitide
Blood samples were collected at pre-specified time points to determine the tmax of enlicitide in participant's plasma. Tmax was defined as time to the maximum concentration of enlicitide reached.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, 24, 36, 48, 72, 120, and 168 hours postdose
Apparent Terminal Half-life (t1/2) of Enlicitide
Blood samples were collected at pre-specified timepoints to determine the t1/2 of enlicitide. t1/2 was defined as the time required to divide the enlicitide plasma concentration by two after reaching pseudo-equilibrium, following a single dose of enlicitide.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, 24, 36, 48, 72, 120, and 168 hours postdose
Apparent Clearance (CL/F) of Enlicitide
Blood samples were collected at pre-specified timepoints to determine the CL/F of enlicitide. CL/F was the apparent total clearance of enlicitide in plasma over time, assessed as the rate at which enlicitide was removed from the plasma.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, 24, 36, 48, 72, 120, and 168 hours postdose
Apparent Volume of Distribution During Terminal Phase (Vz/F) of Enlicitide
Blood samples were collected at pre-specified timepoints to determine the Vz/F of enlicitide. Vz/F was the apparent volume of distribution of enlicitide between the plasma and the rest of the body, after dose, assessed as the total volume of enlicitide that would need to be uniformly distributed to achieve the desired plasma drug concentration.
Time frame: Predose and 0.5, 1, 1.5, 2, 3, 5, 8, 12, 24, 36, 48, 72, 120, and 168 hours postdose
Number of Participants Who Experienced a Treatment Emergent Adverse Event (TEAE)
An adverse event (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. An AE was considered treatment-emergent if the onset date and time is at the time of or after the first study drug administration. The number of participants who experienced a TEAE were reported.
Time frame: Up to approximately 6 weeks
Number of Participants Who Experienced An Adverse Event (AE)
An AE was 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. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Number of participants who experienced an AE were reported.
Time frame: Up to approximately 6 weeks
Number of Participants Who Discontinued Study Due to an AE
An AE was 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. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Number of participants who discontinued from the study due to an AE were reported..
Time frame: Up to approximately 6 weeks
