A Clinical Study of MK-6552 and Modafinil in Healthy Men (MK-6552-005)

Phase 1
Completed
Conditions
Healthy
Narcolepsy
Interventions
Registration Number
NCT06665230
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The goal of this study is to learn what happens to MK-6552 in a person's body over time. Researchers will compare what happens to levels of MK-6552 in people's blood when it is taken with and without modafinil. Researchers also want to learn about the safety of MK-6552 taken with and without modafinil and if people tolerate it.

Primary Outcome Measures
NameTimeMethod
Number of Participants Who Experience an Adverse Event (AE)Up to approximately 1 month

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 Treatment Due to an AEUp to approximately 19 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.

High Dose Modafinil Effect: Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-inf) of MK-6552At designated timepoints (up to approximately 36 hours postdose)

Blood samples will be collected to determine the AUC0-inf of MK-6552 in the presence of high dose modafinil.
