Brief summary

The goal of the study is to learn what happens to levels of nemtabrutinib (MK-1026) in a healthy person's body over time. Researchers will compare what happens to nemtabrutinib in the body when it is given with or without another medicine called diltiazem.

Design outcomes

Primary

MeasureTime frameDescription
Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-Inf) of NemtabrutinibUp to approximately 4 weeksBlood samples will be collected to determine the AUC0-inf of nemtabrutinib.
Maximum Plasma Concentration (Cmax) of NemtabrutinibUp to approximately 4 weeksBlood samples will be collected to determine the Cmax of nemtabrutinib.
Area Under the Concentration-Time Curve from Time 0 to Last (AUC0-Last) of NemtabrutinibUp to approximately 4 weeksBlood samples will be collected to determine the AUC0-last of nemtabrutinib.
Time to Maximum Plasma Concentration (Tmax) of NemtabrutinibUp to approximately 4 weeksBlood samples will be collected to determine the Tmax of nemtabrutinib.
Apparent Terminal Half-life (t1/2) of NemtabrutinibUp to approximately 4 weeksBlood samples will be collected to determine the t1/2 of nemtabrutinib.
Apparent Clearance (CL/F) of NemtabrutinibUp to approximately 4 weeksBlood samples will be collected to determine the CL/F of nemtabrutinib.
Volume of Distribution During Terminal Phase (Vz/F) of NemtabrutinibUp to approximately 4 weeksBlood samples will be collected to determine the Vz/F of nemtabrutinib.

Secondary

MeasureTime frameDescription
Number of Participants Who Experience an Adverse Event (AE)Up to approximately 5 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.
Number of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 3 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.
