Pharmacokinetics of Leritrelvir(RAY1216) in Participants With Hepatic Impairment

A Phase I Single Dose, Non-Randomised, Open-Label, Parallel Group Study to Investigate the Effect of Hepatic Impairment on the Pharmacokinetics, Safety and Tolerability of Leritrelvir(RAY1216)

This study will assess the effect of hepatic impairment on the pharmacokinetics (PK), safety and tolerability of Leritrelvir(RAY1216)

Inclusion Criteria:

1. Participant must be ≥ 18 to ≤ 70 years, at the time of signing the informed consent.

   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:

1. Participants with an allergic disposition (multiple drug and food allergies) or who, as determined by the investigator, are likely to be allergic to the investigational drug product or any component of the investigational drug product.

2. QTcF (male) > 470ms，QTcF (female) > 480ms

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.
