Study Endpoints
Primary Endpoints
Area Under the Concentration Versus Time Curve from 0 to Infinity (AUC0-inf) After a Single Dose of MK-5684
At protocol specific time points pre-dose and up to 72 hours post-dose

Blood samples will be collected to determine the AUC0-inf of MK-5684 in plasma.

Area Under the Concentration Versus Time Curve From 0 to the Time of the Last Quantifiable Sample (AUC0-last) of MK-5684
At protocol specific time points pre-dose and up to 72 hours post-dose

Blood samples will be collected to determine the AUC0-last of MK-5684 in plasma.

Area Under the Concentration Versus Time Curve From 0 to 24 Hours After Dosing (AUC0-24) of MK-5684
At protocol specific time points pre-dose and up to 24 hours post-dose

Blood samples will be collected to determine the AUC0-24 of MK-5684 in plasma.

Maximum Observed Drug Concentration (Cmax) After the Administration of a Given Dose of MK-5684
At protocol specific time points pre-dose and up to 72 hours post-dose

Blood samples will be collected to determine the Cmax of MK-5684 in plasma.

Time to Maximum Observed Plasma Drug Concentration (Tmax) of MK-5684
At protocol specific time points pre-dose and up to 72 hours post-dose

Blood samples will be collected to determine the Tmax of MK-5684 in plasma.

Apparent Terminal Half-Life (t½) of MK-5684
At protocol specific time points pre-dose and up to 72 hours post-dose

Blood samples will be collected to determine the t1/2 of MK-5684 in plasma.

Apparent Clearance (CL/F) of MK-5684
At protocol specific time points pre-dose and up to 72 hours post-dose

Blood samples will be collected to determine the CL/F of MK-5684 in plasma.

Apparent Volume of Distribution During Terminal Phase (Vz/F) of MK-5684
At protocol specific time points pre-dose and up to 72 hours post-dose

Blood samples will be collected to determine the Vz/F of MK-5684 in plasma.

ArmTypeDescription
Group 1: Severe Renal Impairment (RI)EXPERIMENTALParticipants 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).
Group 2: End-stage renal disease (ESRD)EXPERIMENTALParticipants 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.
Group 3: Healthy ParticipantsEXPERIMENTALParticipants 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).
