Outcome Measures

Primary Outcomes (2)

  • Number of Participants Who Experience One or More Adverse Events (AEs)

    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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experienced an AE is presented.

    Up to approximately 169 days

  • Number of Participants Who Discontinue Study Intervention Due to an AE

    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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who discontinued study intervention due to an AE is presented.

    Up to approximately 85 days

Secondary Outcomes (8)

  • Area Under the Curve (AUC) From Days 1-15 (AUC1-15) of MK-6194

    Day 1 (Predose and 12 hours postdose), Day 8, and Day 15

  • AUC From Days 29-43 (AUC29-43) of MK-6194

    Day 29 (Predose and 12 hours postdose), Day 36, and Day 43

  • Peak Serum Concentration (Cmax) of MK-6194 (Day 1 to 29)

    Day 1 (Predose and 12 hours postdose), Day 8, Day 15, and Day 29 (Predose and 12 hours postdose)

  • Minimum Serum Concentration (Ctrough) of MK-6194 (Day 1 to 29)

    Predose on Days 15 and 29

  • Time to Peak Serum Concentration (Tmax) of MK-6194 (Day 1 to 29)

    Day 1 (Predose and 12 hours postdose), Day 8, Day 15, and Day 29 (Predose and 12 hours postdose)

  • +3 more secondary outcomes
