A Study of Diltiazem With a Single Dose of MK-6552 in Healthy Adult Participants (MK-6552-007)

Phase 1
Completed
Conditions
Healthy
Interventions
Registration Number
NCT06662396
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The main goal of this study is to learn what happens to MK-6552 in a person's body over time (a pharmacokinetic or PK study). Researchers want to know what happens to MK-6552 in healthy adults when a single dose of MK-6552 is given with multiple doses of diltiazem. The researchers believe that multiple doses of diltiazem will not affect the highest amount of MK-6552 in the blood.

Primary Outcome Measures
NameTimeMethod
Maximum Plasma Concentration (Cmax) of MK-6552Pre-dose and at designated time points up to 24 hours post dose

Blood samples will be collected to determine the Cmax of MK-6552 in plasma.

Secondary Outcome Measures
NameTimeMethod
Time to Maximum Plasma Concentration (Tmax) of MK-6552Pre-dose and at designated time points up to 96 hours post dose

Blood samples will be collected to determine the Tmax of MK-6552 in plasma.

Concentration of MK-6552 at 6 Hours Postdose (C6h)Pre-dose and at designated time points up to 6 hours post dose

Blood samples will be collected to determine the C6h of MK-6552 in plasma.

Concentration of MK-6552 at 8 Hours Postdose (C8h)Pre-dose and at designated time points up to 8 hours post dose

Blood samples will be collected to determine the C8h of MK-6552 in plasma.

Apparent Clearance (CL/F) of MK-6552Pre-dose and at designated time points up to 96 hours post dose

Blood samples will be collected to determine the CL/F of MK-6552 in plasma.

Apparent Volume of Distribution During Terminal Phase (Vz/F) of MK-6552Pre-dose and at designated time points up to 96 hours post dose

Blood samples will be collected to determine the Vz/F of MK-6552 in plasma.

Apparent Terminal Half-Life (t1/2) of MK-6552Pre-dose and at designated time points up to 96 hours post dose

Blood samples will be collected to determine the t1/2 of MK-6552 in plasma.

Number of Participants Who Experience and Adverse Event (AEs)Up to approximately 20 days

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.

Number of Participants Who Discontinue Study Due to an AEUp to approximately 20 days

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.

Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-inf) of MK-6552Pre-dose and at designated time points up to 96 hours post dose

Blood samples will be collected to determine the AUC0-inf of MK-6552 in plasma.

Area Under the Concentration-Time Curve from Time 0 to 24 hours (AUC0-24) of MK-6552Pre-dose and at designated time points up to 24 hours post dose

Blood samples will be collected to determine the AUC0-24 of MK-6552 in plasma.
