A Study of the Effect of Nemtabrutinib (MK-1026) on the Plasma Levels of Digoxin in Healthy Participants (MK-1026-012)

Phase 1
Completed
Conditions
Healthy
Interventions
Registration Number
NCT06625827
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The goal of the study is to learn what happens to levels of digoxin in a healthy person's body over time. Researchers will compare what happens to digoxin in the body when it is given with and without another medicine called nemtabrutinib. Researchers are testing if digoxin levels in the body are different when digoxin is given with or without nemtabrutinib.

Primary Outcome Measures
NameTimeMethod
Area under the Concentration-Time Curve from Time 0 to Infinity (AUC0-Inf) of DigoxinAt designated timepoints (up to approximately 7 days)

Blood samples will be collected to determine the AUC0-Inf of digoxin.

Secondary Outcome Measures
NameTimeMethod
Area Under the Concentration-Time Curve from Time 0 to Last (AUC0-Last) of DigoxinAt designated timepoints (up to approximately 7 days)

Blood samples will be collected to determine the AUC0-Last of digoxin.

Maximum Plasma Concentration (Cmax) of DigoxinAt designated timepoints (up to approximately 7 days)

Blood samples will be collected to determine the Cmax of digoxin.

Plasma Concentration 24 Hours Postdose (C24) of DigoxinAt designated timepoints (up to approximately 24 hours)

Blood samples will be collected to determine the C24 of digoxin.

Time to Maximum Plasma Concentration (Tmax) of DigoxinPredose and at designated timepoints (up to approximately 7 days)

Blood samples will be collected to determine the Tmax of digoxin.

Apparent Volume of Distribution (Vz/F) of DigoxinAt designated timepoints (up to approximately 7 days)

Blood samples will be collected to determine the Vz/F of digoxin.

Number of Participants Who Experience an Adverse Event (AE)Up to approximately 8 weeks

An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be reported.

Number of Participants Who Discontinue Study Due to an AEUp to approximately 8 weeks

An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who discontinue study due to an AE will be reported.

Apparent Terminal Half-life (t1/2) of DigoxinAt designated timepoints (up to approximately 7 days)

Blood samples will be collected to determine t1/2 of digoxin.

Apparent Clearance (CL/F) of DigoxinAt designated timepoints (up to approximately 7 days)

Blood samples will be collected to determine the CL/F of digoxin.
