   Participants with hepatic impairment only:

4. Supporting documents confirming that the participant has liver cirrhosis with hepatic impairment must be available.
5. Unless otherwise stated, participants must have been on stable doses and regimens of the concomitant medication for at least 4 weeks before screening, or treatment-naïve participants

Exclusion Criteria:

6. Smoking averaged more than 10 cigarettes per day in the 3 months prior to screening

   Participants with Normal Hepatic Function Only:

7. Any history of hepatic impairment, or potential presence of liver function impairment by physical examination and laboratory examination at screening.

   Participants with Hepatic Impairment Only:

8. Any history of clinically serious illness or disease or condition except for primary liver disease that the investigator believes may affect the results of the trial, including but not limited to a history of circulatory, endocrine, nervous, digestive, urinary, respiratory or hematological, immune, psychiatric, and metabolic disorders.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum observed plasma concentration (Cmax)	The Cmax of a single dose of Leritrelvir in participants with impaired hepatic function and controls with normal hepatic function will be evaluated and compared.	Day 1 to Day 4
Area under the concentration-time curve from time zero to infinity (AUCinf)	The AUCinf of a single dose of Leritrelvir in participants with impaired hepatic function and controls with normal hepatic function will be evaluated and compared.	Day 1 to Day 4
Area under the concentration-time curve from time zero to last time of quantifiable concentration (AUClast)	The AUClast of a single dose of Leritrelvir in participants with impaired hepatic function and controls with normal hepatic function will be evaluated and compared.	Day 1 to Day 4

Secondary Outcome Measures

Outcome Measure	Time Frame
Number of participants with drug-related adverse events as assessed by CTCAE v5.0	Day 1 to Day 7
