Brief summary
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 the effect of this new study medicine enlicitide on digoxin (medicine used in heart disease) over time (a pharmacokinetic or PK study). Researchers will compare what happens to digoxin in the body over time when it is given with this new study medicine enlicitide in healthy adult participants.
Interventions
DRUGEnlicitide
Participants will receive 20 mg enlicitide/180 mg sodium caprate coadministered with 0.25mg Digoxin orally on Day 1, Period 2 in Arm A and on Day 1 Period 1 in Arm B.
DRUGDigoxin
Participants will receive 0.25 mg digoxin orally on Day 1 Period 1 in Arm A and Day 1 Period 2 in Arm B. They also receive Digoxin orally on Day 1, Period 2 in Arm A and on Day 1 Period 1 in Arm B coadministered with oral 20 mg enlicitide/180 mg sodium caprate.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Area Under the Concentration-time Curve From Time Zero to Infinity (AUC0-inf) for Digoxin in Plasma | At designated timepoints (up to 5 days) | AUC0-inf is the area under the plasma concentration versus time curve (AUC) for digoxin, from time zero (pre-dose) to extrapolated infinite time. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Terminal half life (T½) for Digoxin in Plasma | At designated timepoints (up to 5 days) | T1/2 is defined as the time taken for the plasma concentration or the amount of digoxin in the body to be reduced by half. |
| Apparent Clearance (CL/F) for Digoxin in Plasma | At designated timepoints (up to 5 days) | Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. |
| Apparent Volume of Distribution During Terminal Phase (Vz/F) for Digoxin in Plasma | At designated timepoints (up to 5 days) | Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Vz/f after oral dose of digoxin is influenced by the fraction absorbed. |
| Number of Participants With Treatment Emergent Adverse Events (TEAEs): | Up to ~ 28 days. | An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. TEAEs are defined as all AEs that occurred at or after the first dose of the investigational product and through the last follow-up date. |
| Tmax (Time to Maximum Concentration) for Digoxin in Plasma | At designated timepoints (up to 5 days) | The time to reach Cmax (Tmax) is determined. Blood samples will be collected at designated timepoints (up to 5 days) post-dose to determine the maximum concentration (Cmax) of digoxin. |
| Standard and Orthostatic Vital Signs | Up to ~ 28 days | Single measurements of body temperature, respiratory rate, blood pressure, and heart rate, and triplicate measurements of blood pressure and heart rate will be measured. Orthostatic vital signs (i.e., heart rate and blood pressure) will be measured, Measurements will be collected with participants in a semi-recumbent position and then collected when in a standing position. |
| 12-lead Electrocardiogram (ECGs) | Up to ~ 28days | Single and triplicate 12-lead ECGs will be performed. Triplicate 12-lead ECGs will be performed within an approximately 6-minute time window. ECGs will be performed with participants in a supine position for at least 5 minutes. In each period, triplicate ECGs will be measured within 3 hours prior to dosing. When scheduled post dose, single ECGs will be performed within ±20 minutes of the scheduled time point. |
| Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUC0-last) for Digoxin in Plasma | At designated timepoints (up to 5 days) | Area under the plasma concentration versus time curve from time zero to the last sampling time t at which the concentration is at or above the lower limit of quantification (LLQ). |
| Cmax (Maximum Concentration) for Digoxin in Plasma | At designated timepoints (up to 5 days) | Blood samples will be collected at at designated timepoints (up to 5 days) post-dose to determine the Cmax of Digoxin. |
| Number of Participants With Clinical Laboratory Abnormalities | Up to ~ 28 days | Clinical laboratory test include serum chemistry, hematology and urinalysis. Clinical laboratory abnormalities were recorded and reported as TEAE. TEAEs are defined as all AEs that occurred at or after the first dose of the investigational product or device implant surgery (whichever occurred earlier) and through the last follow-up date. |
