Adverse events — posted to ClinicalTrials.gov
Time frame: 14 days after last dose (up to Day 24).
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
This study will compare the pharmacokinetics (PK) of grazoprevir (MK-5172) when administered to participants with mild, moderate or severe hepatic insufficiency (assessed by the criteria of the Child-Pugh's scale) with the PK of grazoprevir when administered to healthy participants.
