Brief summary

The goal of the study is to learn what happens to levels of MK-6916 in a healthy person's body over time. Researchers will compare what happens to MK-6916 in the body when it is given with or without another medicine called diltiazem.

Primary

MeasureTime frameDescription
Apparent Terminal Half-life (t1/2) of MK-6916Predose and at designated time points (up to 8 weeks)Blood samples will be collected to determine the t1/2 of MK-6916.
Apparent Clearance (CL/F) of MK-6916Predose and at designated time points (up to 8 weeks)Blood samples will be collected to determine the CL/F of MK-6916.
Apparent Volume of Distribution (Vz/F) of MK-6916Predose and at designated time points (up to 8 weeks)Blood samples will be collected to determine the Vz/F of MK-6916.
Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-Inf) of MK-6916Predose and at designated time points (up to 8 weeks)Blood samples will be collected to determine the AUC0-inf of MK-6916.
Area Under the Concentration-Time Curve from Time 0 to 24 hours (AUC0-24hrs) of MK-6916Predose and at designated time points (up to 24 hours)Blood samples will be collected to determine the AUC0-24 of MK-6916.
Plasma Concentration at 24 Hours (C24) of MK-6916Predose and at designated time points (up to 24 hours)Blood samples will be collected to determine the C24 of MK-6916.
Plasma Concentration at 12 Hours (C12) of MK-6916Predose and at designated time points (up to 12 hours)Blood samples will be collected to determine the C12 of MK-6916.
Maximum Plasma Concentration (Cmax) of MK-6916Predose and at designated time points (up to 8 weeks)Blood samples will be collected to determine the Cmax of MK-6916.
Time to Maximum Plasma Concentration (Tmax) of MK-6916Predose and at designated time points (up to 8 weeks)Blood samples will be collected to determine the Tmax of MK-6916.

Secondary

MeasureTime frameDescription
Number of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 8 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.
Number of Participants Who Experience an Adverse Event (AE)Up to approximately 8 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 experience an AE will be reported.
