A Clinical Study to Assess the Effect of Enlicitide on How the Body Processes Digoxin in Healthy Adult Participants (MK-0616-031)

Phase 1
Completed
Conditions
Healthy
Interventions
Registration Number
NCT06597760
Lead Sponsor
Merck Sharp & Dohme LLC
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.

Sequence 1: 0.25mg Digoxin-->0.25mg Digoxin plus 20mg enlicitide/180mg Sodium CaprateEnlicitideParticipants will receive 1 tablet of 0.25mg Digoxin on Day 1 of period 1 and 1 tablet of 0.25mg Digoxin coadministered with 1 tablet of 20 mg enlicitide/180 mg sodium caprate on Day 1 of Period 2.

Primary Outcome Measures
NameTimeMethod
Area Under the Concentration-time Curve From Time Zero to Infinity (AUC0-inf) for Digoxin in PlasmaAt 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 Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUC0-last) for Digoxin in PlasmaAt 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 PlasmaAt 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.

Tmax (Time to Maximum Concentration) for Digoxin in PlasmaAt 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.

Terminal half life (T½) for Digoxin in PlasmaAt 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 PlasmaAt 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 PlasmaAt 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.

Number of Participants With Clinical Laboratory AbnormalitiesUp 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.

Standard and Orthostatic Vital SignsUp 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.
