Day 9 was a non-hemodialysis day for these participants. On Day 10, hemodialysis for these participants was timed to occur after the median Tmax (\~5 hours postdose).
Participants With Severe Renal Impairment: Day 10
n=8 Participants
Participants with Severe Renal Impairment (SRI, estimated glomerular filtration rate \<30 mL/min/1.73 m\^2) received once daily Grazoprevir 100 mg tablet and Elbasvir 50 mg tablet for 10 days.
Healthy Participants: Day 10
n=8 Participants
Healthy participants (estimated glomerular filtration rate \>=80 mL/min/1.73 m\^2) received once daily Grazoprevir 100 mg tablet and Elbasvir 50 mg tablet for 10 days.

PRIMARY outcome

Timeframe: Up to 24 hours postdose

Population: The Per Protocol population included all participants who complied with the protocol sufficiently to ensure that these data likely to exhibit the effects of treatment, according to the underlying scientific model. End Stage Renal Disease for Non-HD Day 9 was not reported since only 24-hour collections were made on that day.

Blood for determination of Elbasvir concentration was collected predose and 0.5, 1, 2, 3, 4, 5, 5.5, 6, 7, 8, 12, 16, and 24 hours postdose on Day 10
