A Study to Evaluate the Effect of MK-5684 in Male Participants With Severe Renal Impairment (RI) and With End-stage Renal Disease (ESRD) (MK-5684-010)

Purpose

The goal of the study is to learn what happens to levels of MK-5684 in people with severe renal impairment and end-stage renal disease versus a healthy person's body over time. Researchers will compare what happens to MK-5684 after hemodialysis in people with severe renal impairment and end-stage renal disease versus healthy people.

Experimental
Group 1: Severe Renal Impairment (RI)
Participants will receive a single oral dose of MK-5684 under fasting conditions (on an empty stomach after a 10-hour overnight fast) on Day 1 and a single dose of Hormone replacement therapy (HRT) (prednisone and fludrocortisone) administered approximately 4.5 hours after MK-5684 dosing under fed conditions (eating a normal meal).

Experimental
Group 2: End-stage renal disease (ESRD)
Participants will receive a single oral dose of MK-5684 under fasting conditions (on an empty stomach after a 10-hour overnight fast) in Period 1 and Period 2. In Period 1, participants will receive a single oral dose of MK-5684 approximately 30 minutes prior to their normally scheduled hemodialysis (HD), followed by HRT under fed conditions (eating a normal meal) 4.5 hours after MK-5684 dosing. In Period 2, participants will receive a single oral dose of MK-5684 immediately followed by completion of their normally scheduled HD, and by HRT under fed conditions (eating a normal meal) 4.5 hours after MK-5684 dosing.
