Eligibility Criteria

Inclusion Criteria

• Body mass index (BMI) in the range of 18.0 to 40.0 kilograms (kg)/meter squared, inclusive, with a minimum body weight of 50 kg at screening.
• Stable creatinine clearance.

Participants with RI must have met the following additional criteria to be enrolled in this study

• A stable medication regimen was required. Concomitant medications must have been approved by the Sponsor and Investigator (or designee) or pre-specified in the protocol.
• Abnormal laboratory values must not have been clinically relevant at screening or check-in.
• Participants were in good general health at screening and check-in, allowing for the concurrent illnesses associated with chronic kidney disease.
• Stable severe RI.

Healthy matched control participants with normal renal function must have met the following additional criteria to be enrolled in this study

• In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead electrocardiogram, and vital sign measurements at screening or check-in, as determined by the Investigator (or designee).
• Participants had normal renal function.
• Participants must have been demographically matched to a renally impaired participant by age (± 10 years), sex, and BMI (± 20%) at screening.

Exclusion Criteria

• History of any medical or psychiatric condition or disease (aside from RI for RI participants) that might have limited the participant's ability to complete or participate in this clinical study, confound the results of the study, or pose an additional risk to the participant by their participation in the study.
• History of procedures that could alter absorption or excretion of orally administered drugs.
• Body temperature ≥ 38°Celsius on Day - 1 or Day 1 predose; history of febrile illness, or other evidence of infection, within 14 days prior to study drug administration.
• History or presence of drug or alcohol abuse within previous year; current tobacco/nicotine user; positive for alcohol and/or drug screen at screening.
• Participation in any other investigational study drug trial in which receipt of an investigational study drug occurred within 5 half-lives (if known) or 30 days prior to check-in, whichever was longer.
• For matched control participants, use of any prescription medications/products within 14 days prior to check-in and use of any over-the-counter, nonprescription preparations within 7 days prior to check-in, unless deemed acceptable by the Investigator (or designee).
• Donation of whole blood from 3 months prior to study drug administration, or of plasma from 30 days prior to study drug administration; receipt of blood products within 6 months prior to check-in.
• Participant required dialysis within the last 3 months prior to check-in.
• Participant did not produce sufficient urine output to permit urine sampling at screening and/or check-in; history of urinary incontinence prior to check-in.
• History of kidney transplant or actively on a transplant waiting list prior to check-in.
• Any acute or chronic non-renal condition prior to check-in that would have limited the participant's ability to complete or participate in this clinical study.
• Any major surgery within 4 weeks of study drug administration.

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 75 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: Yes
