What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the study drug whether or not it is considered related to the study drug. The number of participants who experience an AE will be reported. | Up to approximately 164 days | 
| Number of Participants Who Discontinue 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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the study drug whether or not it is considered related to the study drug. The number of participants who discontinue study due to an AE will be reported. | Up to approximately 164 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Concentration-Time Curve of MK-2060 From Time 0 to Infinity (AUC 0-inf) | Blood samples will be collected at specified intervals for the determination of AUC0-inf. AUC0-inf is defined as the area under the concentration-time curve of pembrolizumab from time zero to infinity. | Day 1-3: Predose and 1, 12, 24, 48 and 52 hours postdose; once daily on Days 5, 12, 15, 22, 60, 90, 150: postdose; and twice daily on Days 8, 29, 120: pre- and post-dialysis | 
| Area Under the Plasma Concentration-Time Curve of MK-2060 From Time 0 to Last (AUC0-last) | Blood samples will be collected at specified intervals for the determination of AUC0-last. AUC0-last is defined as the area under the plasma concentration-time curve from time zero to time of last measurable concentration of MK-2060. | Day 1-3: Predose and 1, 12, 24, 48 and 52 hours postdose; once daily on Days 5, 12, 15, 22, 60, 90, 150: postdose; and twice daily on Days 8, 29, 120: pre- and post-dialysis |
