Pharmacokinetics (PK) and Safety of a Single Intravenous (IV) Dose of MK-3866 in Participants With Impaired Renal Function and in Healthy Controls (MK-3866-005)

Inclusion Criteria

• Females of non-childbearing potential. Male participants with female partner(s) of child-bearing potential agree to use a medically acceptable method of contraception during the study and for 90 days after dosing. If partner is pregnant, males agree to use a condom; if partner is of child-bearing potential, partner must use additional birth control
• Male participants agree not to donate sperm from the first dose until 90 days after dosing
• Adequate venous access

Renal Impaired Participants

• Liver function tests (serum alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) and serum bilirubin (total and direct) within upper limit of normal
• Panels A, B, and C: no clinically significant change in renal status at least 1 month prior to dosing and not currently or previously been on hemodialysis
• Panel E only: ESRD maintained on stable regimen of at least 3 times per week HD for at least 3 months prior to first dosing

Healthy Participants

• Age within ± 15 years of the mean age of participants with impaired renal function to which the healthy participant is matched
• Medically healthy as per medical history, physical examination, vital signs, 12-lead electrocardiograms (ECGs), and clinical laboratory safety tests
• Blood urea nitrogen, liver function tests (ALT, AST, alkaline phosphatase [ALP]), and serum bilirubin (total and direct) within upper limit of normal.

Exclusion Criteria

• Mentally/legally incapacitated, or significant emotional problems or significant psychiatric disorder
• History of clinically significant endocrine, gastrointestinal, cardiovascular, hematological, hepatic, immunological, respiratory, genitourinary or major neurological abnormalities or diseases
• History of any illness that might confound the results of the study or poses an additional risk to the participant by their participation in the study
• Clinically significant history of cancer
• Smoker and/or has used nicotine or nicotine-containing products within 3 months prior to screening
• Female participants of childbearing potential, pregnant, or lactating
• Positive results for urine or saliva drug screen and/or urine or breath alcohol screen at screening or check-in

• Consumes excessive amounts of coffee, tea, cola, energy-drinks, or other caffeinated beverages per day
• Major surgery, donated or lost 1 unit of blood within 4 weeks prior to screening, or donated plasma within 7 days prior to dosing in Part 1 or first dose in Part 2

Renal Impaired Participants

• Panels A, B, and C: Failed renal transplant or has had nephrectomy
• Panels A, B, and C: Rapidly fluctuating renal function, as determined by historical measurements; or demonstrated/suspected renal artery stenosis
• Panel E only: Has required frequent emergent HD (≥3) within a year prior to first dosing

Healthy Participants

• Renal transplant or nephrectomy
