Study summary

The goal of this study is to learn what happens to levels of nemtabrutinib in a 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 itraconazole.

What researchers measure

Primary outcomes

  1. Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-Inf) of Nemtabrutinib

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

    Time frame: At designated time points (up to approximately 10 days postdose)

  2. Area Under the Concentration-Time Curve from Time 0 to Last (AUC0-last) of Nemtabrutinib

    Blood samples will be collected to determine the AUC0-last of nemtabrutinib in plasma.

    Time frame: At designated time points (up to approximately 10 days postdose)

  3. Maximum Plasma Concentration (Cmax) of Nemtabrutinib

    Blood samples will be collected to determine the Cmax of nemtabrutinib in plasma.

    Time frame: At designated time points (up to approximately 10 days postdose)

  4. Time of Maximum Plasma Concentration (Tmax) of Nemtabrutinib

    Blood samples will be collected to determine the Tmax of nemtabrutinib in plasma.

    Time frame: At designated time points (up to approximately 10 days postdose)

  5. Apparent Terminal Half-life (t1/2) of Nemtabrutinib

    Blood samples will be collected to determine the t1/2 of nemtabrutinib in plasma.

    Time frame: At designated time points (up to approximately 10 days postdose)

  6. Apparent Clearance (CL/F) of Nemtabrutinib

    Blood samples will be collected to determine the CL/F of nemtabrutinib in plasma.

    Time frame: At designated time points (up to approximately 10 days postdose)

  7. Apparent Volume of Distribution (Vz/F) of Nemtabrutinib

    Blood samples will be collected to determine the Vz/F of nemtabrutinib in plasma.

    Time frame: At designated time points (up to approximately 10 days postdose)

Secondary outcomes

  1. Number of Participants Who Experience an Adverse Event (AE)

    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.

    Time frame: Up to approximately 6 weeks

  2. Number of Participants Who Discontinue from Study Due to an AE

    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.

    Time frame: Up to approximately 6 weeks
