A Study of HRS9531 in Participants With Impaired Kidney Function and Healthy Subjects

The purpose of this study is to assess how fast HRS9531 gets into the blood stream and how long it takes the body to remove it in participants with impaired kidney function compared to healthy participants.

14. The need to follow a special diet and unable to follow the diet requirement of protocol;
15. The investigator considers that the subject has any other factors that would make it inappropriate to participate in this study

    3. Use of medications determined to be unsuitable by the investigator (including over-the-counter medication, prescription medication and herbal preparations) within the 14 days prior to screening;
    4. Have clinical laboratory test results outside normal reference range for the population or investigator site and judged to be clinically significant by the investigator;
