NCT06662396

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.

Outcome Measures

Primary Outcomes (1)

  • Maximum Plasma Concentration (Cmax) of MK-6552

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

    Pre-dose and at designated time points up to 24 hours post dose

Secondary Outcomes (10)

  • Number of Participants Who Experience and Adverse Event (AEs)

    Up to approximately 20 days

  • Number of Participants Who Discontinue Study Due to an AE

    Up to approximately 20 days

  • Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-inf) of MK-6552

    Pre-dose and at designated time points up to 96 hours post dose

  • Area Under the Concentration-Time Curve from Time 0 to 24 hours (AUC0-24) of MK-6552

    Pre-dose and at designated time points up to 24 hours post dose

  • Time to Maximum Plasma Concentration (Tmax) of MK-6552

    Pre-dose and at designated time points up to 96 hours post dose

  • +5 more secondary outcomes

Study Arms (1)

MK-6552 + Diltiazem

EXPERIMENTAL

Participants receive a single dose of MK-6552 on Period 1 Day 1. Participants receive a Diltiazem every day (QD) for 6 days (Period 2 Days 1-6). On Period 2 Day 2 participants receive a single dose of MK-6552.
